Washington, D. C., September 16, 1935.
Secretary of Agriculture.
DEAR MR. SECRETARY: I submit herewith a report of the work of
the Bureau of Entomology and Plant Quarantine for the fiscal year
ended June 30, 1935.
Sincerely yours,


In accord with the reorganization directed by the Secretary and approved by
Congress, the investigational work on insects previously carried on in the Bureau of Entomology and the activities concerned with control and eradication of plant pests and the enforcement of plant quarantines previously carried on in the Bureau of Plant Quarantine, together with the functions concerned with the control and eradication of plant diseases directed by the Bureau of Plant Industry, were consolidated at the beginning of the fiscal year into the newly created Bureau of Entomology and Plant Quarantine.
Effective September 1, the chemical work on insecticides and fungicides previously carried on in the Bureau of Chemistry and Soils was transferred, by order of the Secretary, to the Bureau of Entomology and Plant Quarantine.
These investigations on the chemistry of insecticides continued under the direction of R. C. Roark as leader of the Division of Insecticide Investigations.
The unfortunate and untimely death of Karl F. Kellerman, who had charge of the Division of Plant Disease Control of the Bureau of Entomology, was followed by the reassignment of certain activities previously carried on in that unit. Stanley B. Fracker, who had been in charge of the Division of Domestic Plant Quarantines of the Bureau of Plant Quarantine, was designated as leader of the Division of Plant Disease Control and the scope of the Division restricted to work concerned with the control and prevention of spread of white pine blister rust and black stem rust of small grains. B. M. Gaddis was placed in charge of the Division of Domestic Plapnt Quarantines and the scope of the Division enlarged to include activities on the control and prevention of spread of the phony peach disease and citrus canker. The field direction of the work on the eradication of the Dutch eln disease was assi.-Ded to L. H. Worthley, who continued as field leader in charge of work on control and prevention of spread of the Japanese beetle and certitieition of products to meet the requirements of Federal and State quarantliles oi this pest, the -vl)sy, brown-tail, and satin moths, and the European c,,rn borer. Investigations on the physiology and toxicology of insects, handled as a unit in the Bureau of Entomology, were consolidated with th ,we co ncerned with the commercial application of control measures in the I bureau of Plant Quarantine, under the direction of L. A. Hawkins. The service and investi(ational work on insects attacking shade trees was assigned to the Divisioni of Forest Insect
-A3 During the fiscal year the regular and1secial" activities concerned with the

berry as an aid in combatinig black sten rust, and the control and prevention of spJread of white pine blister rust, were financed uebr allotments of emergency funds rather than being provided for in the regular appropriations made for the work of the Bureau. Special allotments of emergency funds were also made available to aid in the eradication of the Dutch elm disease and measures to suppress an infestation of the Japanese beetle discovered at St. IAluis, 'MO.


During the year the Survey added to the permanent files of information on the distribution and abundance of insects over 12,000 notes on American insect pests in( over 7,000 on insect pests of other countries, bringing the total number now available for consultation to over 226,000. A new feature of the mineographied Insect Pest Survey Bulletin was started by issuing supplemental numbers as an avenue for the publication of more extensive and detailed survey reports on special subjects, such as The Species and Distribution of Grasshoppers Responsible for the 1934 Outbreak, and Insect Notes from Costa Rica in 1934.
During the year, 116 articles covering various phases of the activities of the Bureau were released to the press. A complete program for radio releases was prepared for the year and 39 talks were put on the air. The use of film strips as a means of visual education has been very greatly stimulated during the year. The construction of a comprehensive exhibit on the activities of the Bureau, to be shown at the San Diego Exposition, was planned and supervised. During the year over 100,000 publications were distributed, exclusive of those sent out on regular mailing lists and miscellaneous mimeographed material prepared from time to time.


The major portion of the funds available for the work on apple insects. including a special allotment made by the Pub ic Works Administration, was used for investigations on the codling moth in an effort to develop a satisfactory and practical means of controlling the insect that does not result in objectionable residues at harvest time.
The large-scale tests of various insecticides carried on during the calendar year 1934 at numerous points indicated that lead arsenate is still the most generally satisfactory material available, although not fully effective in the control of severe infestations. Closely approaching lead arsenate in effectivehess was the nicotine-oil treatment. which, however, involves certain difficulties in proctical use. The fixed nicotine materials, nicotine bentonite and nicotine tannate, gave indications uficiently favorable to warrant the hope that a practical insecticide nay exist somewhere in this group of materials. Mixtures of' ground derris, cube, and pyrethruin with kaolin. applied as sprays, were incffvct ive for codling moth control. Laboratory studies to develop new and less object liable insecticidal compounds, preliminary to more extensive field experiment ation with the more promising materials, were continued. During Ie 193a masonI extensive tests are being malde with plienothitzine, a material which is mi;ale by fusing sulphur with diplhenylumine. This compound was first prepared by the Insecticide Division, and in laboratory experiments in 198 it was fIun I to be very toxic to codling tIot iI larvae. Preliminary results of otil field and laboratory experiments in the season of 193 are very encouraging, aItollugh, when combined with mineral oil ald with soybeun Oil, the material has caused serious injury. Mllch further field work Is of courile eded& 441 before the exact possibilities and limitations of this material can he detlrmlilled.

In cooperation with the Yakima, Wash., Fruit Growers Association, experiments have been carried on with the sterilization of orchard boxes and other. containers. By passing them through live steam in an insulated wooden tunnel, it was found entirely feasible to kill practically all codling moth larvae at a cost of $0.75 to $2 per thousand for packing boxes, and at a cost of $1 to $2.67 per thousand for cannery lug boxes.
The large-scale bait-trap experiment conducted at Orleans, Ind., in 1934 indicated that the traps and materials now available will reduce the infestation by about 25 percent. Further studies of the use of baits and bait traps, in the hope of developing sufficiently effective materials and traps for use in direct control, are under way at Vincennes, Ind., and Yakima, Wash. Fundamental studies of the reaction of moths to lights are under way at Geneva, N. Y., in cooperation with the New York Agricultural Experiment Station, and large-scale tests of light traps are being carried on at Orleans, Ind., in cooperation with the Indiana Agricultural Experiment Station.
Further experiments with the control of the codling moth by the use of parasites are under way. The mass liberations of the egg parasite Trichogramma minutum Riley, made in 1934 at Yakima, Wash., and Cornelia, Ga., did not result in any appreciable reduction in the codling moth population. The egg-larval parasite Ascogaster carpocapsae Vier. has been introduced into a number of western and southwestern localities where it did not previously occur.
At Wooster, Ohio, tests are being conducted to determine the effect of oils, and of insecticidal materials that may be added to them, on hibernating larvae of the codling moth. Certain grades of pine-tar oil used at a strength of 50 percent appear to be effective and are more toxic than are other oils tested.

The station at Fort Valley, Ga., has continued its efforts to develop a satisfactory substitute for lead arsenate for the control of the plum curculio on peaches. Fluorine compounds tested during the early summer of 1935 caused serious injury to the fruit. This injury, which appeared to an equal extent on trees sprayed with bariu fluosilicate, with synthetic cryolite, and with natural cryolite, was sufficiently severe to rule out these materials for use on peach trees.
Further studies of the effect of lime-sulphur, applied during the dormant period for the control of the San Jose scale, have revealed the fact that mortality counts made within a month or two after the spraying are very misleading and that, for full information on the effect of lime-sulphur, it is necessary to delay the examination for 4 or 5 months.
The rearing and liberation of imported parasites of the oriental fruit moth have been continued. Some 216 colonies, chiefly of foreign parasites, containing 45,000 parasites, have been released by the workers of the Moorestown, N. J., laboratory in various peach-producing sections in 13 Eastern and Middle Western States. Recovery collections have indicated that the general level of parasitization is increasing, although there has not yet been time for the general establishment of many of the foreign parasites that have been liberated.
The investigations of baits and bait traps for the control of the oriental fruit moth have been transferred from Cornelia, Ga., to Moorestown. N. J., where much better facilities are available for the work.

Numerous possible substitutes for lead arsenate have been tested against the grape berry moth at Sandusky, Ohio. This insect appears to be more, readily controlled than the codling moth, and satisfactory control was obtained with nicotine bentonite, nicotine tannate, nicotine sulphate with mineral oil. and mixtures of ground pyrethrum with kaolin. For the most part these. mixtures cannot be used in a practical way, however, as they apI!arently affected the fruit unfavorably. The mixtures which included kaolin and bentonite left very unsightly deposits on the grapes, which, although nonpoisonous, made the fruit practically unsalable. There is a possibility, however, that the use of certain of these clays may prove unobjectionable, or even advantageous, on grapes produced for juice. Mixtures containing oil r(m ved the bloom from the berries, giving them a very unattractive appearane.

taining 8 pounds of tartar emtic and 5 gallons of molasses in 100 gallo, of spray have caused sever njury. Mist sprays of the same mixtures, o, the other hand, have not c, used appreciable injury. No effect on fruit (Imposition has been observed thus far. Similar experiments have been conducted in the Rio Grande Valley with the cooperation of the Division as Mexican Fruit Fly Control, with similar results.
Further extensive work is being carried on by the Whittier. Calif., station with the control of the citrus thrips (Scirtoth rips citri Moulton). A number of materials other than sulphur are being tested this season, including dusts containing rotenone, zinc sulphate, pyrethrum, and zinc oxide. Tests are also under way with bentonite and blood albumen as stickers for sulphur dusts.
The Whittier station has continued to obtain data on the biology of the California red scale as a basis for a study of the resistance of this insect te umigation with hydrocyanic acid gas.

Investigations on various fruit flies that are potential pests to fruit culture in the continental United States have been continued at laboratories in Honolulu, Hawaii; Mexico City, Mexico; Mayaguez, Puerto Rico; and Balb(a. Canal Zone.
In Honolulu studies to determine the effects of high and low temperatures on the immature stages of the Mediterranean fruit fly in various host fruits have received special attention. Hundreds of thousands of larvae and thousands of infested fruits have been used in these tests. These have centered around the time interval required at 310 to 32o and 108' to 112' F. Laboratory and field studies have also been made to determine the effect a wide variety of poisons may have on adults when used in sweetened sprays. Among the materials tested were various nicotine compounds, copper arsenite, copper tartrate, copper sucrate, and certain salts of cadmium. Some of these are more effective than lead arsenate but none were as toX as tartar emetic. Experiments to develop and determine the usefulness f diff tT~e f traps and
baits in controlling and detecting the presence of adults have been continu 4. special attention being directed to those containing or releasing ammona.
At Mexico City, attention has been directed principally to baits and poisons, for the Mexican fruit fly (Anastrepha ludens Loew) and related forms Anastrepha. The studies on baits indicate that a product of the metabflisnm of yeast or other organisms presents one of the attractive principles. Coppei compounds, particularly copper sucrate, have shown a high degree of toxicity. and a special study has been made of them. Attention has also been given to determine the host preference of various fruit flies occurring in Mexico and to experiments to determine the effect of climatic factors, especially low temperatures, on survival. Adults of both A. lude-ns and A. Serpentina Wied. survived in outdoor air temperatures as low as 220 F., but both are killed when exposed to temperatures reaching a minimum of 140 for a period of -Th hours. A. ludens appears to be more resistant to low temperatures than (()es, A. serpentina.
At Mayaguez, Puerto Rico, the studies have been concerned with Anastrcpha acidusa Walker and A. suspense Loew and have consisted principally o(f te under Puerto Rico conditions.
STwenty-two species of fruit flies are known to occur in the Canal Zone, ai n work at the Balboa laboratory has been concerned principally with tIh d(etermination of facts on the habits and host preferences of the various pjeaio


The phony peach disease, a virus disease intercommunicable among pea(!. plum, apricot, almond, and several other species, is known to have xexiste I in peach philntings in Georgia for more than 50 years. It was not, however, until about 1920 that serious economic damage occurred. The disease is nIow recognized as a potential menace to the commercial growing of p)eamihes in tlhiz country. The limited amount of scouting from 1920 to 1934 showed(l that the disease had spread to other States, and it is now known to be widle-spreati throughout Georgia, Alabama, Mississippi, Louisiana, eastern Texas, and northern Florida, and scattered in South ('arolina.

strictly limited to the development of practicable methods and the dissemination of such information. Diseased trees found in the course of inspection are removed by State inspectors and owners. Orchardists also willingly furnished labor for the destruction of infected trees. In the summer of 1934, after the beginning of the fiscal year, 137 nurseries in 10 infected States were inspected, and more than 300 phony trees in the 1-mile zone were found and removed. In the summer of 1935, 30 nurseries had been inspected up to July 1 and 124 infected trees found in the environs and destroyed.
Many peach growers in Georgia recently expressed confidence that the eradication of escaped peach trees conducted by the Civil Works Administration in the winter of 1983-34, in clearing out wild and abandoned peach trees, had done much toward solving the problem of phony peach disease control. Other growers have commented on the noticeable decrease in the number of curculios infesting trees in orchards so protected, as compared with those not protected. A similar project has been approved for the fiscal year 1906, to be carried on emergency relief funds, for the purpose of destroying wild host plants, chiefly escaped peaches and abandoned orchards, thus removing these reservoirs of regional infection that hamper the regular orchard eradication activities.


The citrus canker eradication campaign is unique in character in that it is the first instance of the use of Federal funds appropriated specifically for the eradication of a plant disease. Despite the skepticism of many specialists who, at the time the work was inaugurated 20 years ago, regarded the effort as foredoomed to failure, the citrus industry has been protected froin the ravages of this destructive disease. The effectiveness of this campaign is definitely proved by the fact that although canker was found on 515 properties in Florida, scattered through 26 counties, and approximately 3,000,000 citrus trees were destroyed because of the disease, no citrus canker has been reported since 1927 in this extremely important citrus-producing State.
During the years from 1915 to June 30, 1933, citrus canker eradication activities were maintained cooperatively with the States of Florida, Alabama, Louisiana, Mississippi, and Texas, and Federal supervision was delegated to the Bureau of Plant Industry until December 1, 1933, when it was transferred to the Bureau of Entomology. During 1934 cooperative inspection work was limited to Louisiana and Texas in areas where incipient infections were known to persist.
In the fiscal year 1935 the project was reorganized and a Bureau representative assignedl to direct activities in the field in cooperation with the State officers. Such field contact gave impetus to the work from the start. A methodical drive was centered in the Galveston area of Texas to search for infection in wild or abandoned trees in wooded bayous, along roadsides, or in nurseries or home plantings. Due to infections developing in relatively young plantings in this area from time to time it was obvious that somewhere in the vicinity lingered undiscovered infected trees and the task was to find and destroy them. From the beginning of the drive in January 1935 to the close of the fiscal year from 2 to 4 inspectors working this area found citrus canker on 31 properties. All infected trees, totaling COO. and exposed trees, totaling 5,728, were destroyed under State authority. All citrus trees located in the day's work were plotted on a map for use in the event of the approval of more extensive eradication under an emergency relief project. Limited scouting during the year failed to disclose any infection in the commercial area of the lhwer Rio Grande Valley or the citrus-growing areas of Mississippi and Alalima. In Louisiana citrus canker was found in three parishes during the summer of 1934. The 14 infected trees and 32 other exposed trees were destroyed and, although grove and fruit inspection has been continued in the iintervoiiing months, no further infection has been discovered in that State. There were 218.904 trees inspected in Louisiana from July to Dceniber 19'4. In Texas the inspection of S29.775 trees in 106 counties during the first half of the fiscal year disclosed 20 infected trees( on 2 proIperties in the Galveston area. These were destroyed.
An extremely important and enouraging factor in the campaign is the recent approval of an emergency relief project to destroy abandoned and escaped citrus trees throughout the citrus-produing areas o' Louisia na and Texas.
There is every reason to believe that c' mt inued system natic scouting in the itrus-producing areas, (f Texas and other States vill ultimately result in coniplete erad talion of citrus ("8iker frt ni the l1n0ted States.

Infested fruit was found in six districts from Weslaco westward to Mission. The first larvae were discovered in February and the last were found during tile clean-up in April. There were 30 premises involved in larval findings. This number includes 1 premise at Premont, Jim Wells County, and 2 premises near Falfurrias, Brooks County. The detailed larval findings are listed in table 4.

SInfested fruit found in packing house at Falfurrias traced to 1 premise. This included in 3 infestations in Falfurrias and Preinont district.

By the use of traps the occurrence of nine other trypetids aside from Anastrepha ludens has been disclosed. Of these A. pallens occurs in largest number and is known to confine its attack to fruits of certain noneconomic native shrubs. A few specimens of the papaya fruit fly Toxotrypana curvicauda Gerst. have been captured, but the species has no economic significance under valley conditions. The other 7 species have not been found infesting fruit and comparatively little is known of their habits; 4 of them represent undescribed species. Of the better known species, A. serpentina was taken 96 times in traps rather generally over the entire area; 179 specimens of A. fralctrculus were taken, also generally distributed; and 4 adults of A. striata were taken from Edinburg, Mission, and McAllen districts.


During the year 30,790 specimens were submitted to the Ilarlingeni, Tex., laboratory for identification. This total includes all the specimens sent in by inspectors, both in Texas and Mexico, but does not include many larvae collected in Matmoros and turned over to t.e Mexican inspector for roaring purposes and transmittal to MIexico) City.


Part of the general dlut ics of the inspection force is gre insl)pec(tion for infested fruit and unsaniitary conditions in thle groves; tree-to-tree inspection on final clean-up); trap operations, and remiioval of alternate host-fruit trees and fruit. This work is carried onil t1r(mulout the year. 1)uring the past year 37,907 grove inspections were made. Traps were examined 331,635 times on 3.474 premises, and 104 alternate host-fruit tre,,- were (lestr)royed on 35 properties with the consent of the owners.

The shipping season of 1934-35 opened on Sep ember 2G and the harvestliig season closed April 2. The last fruit to leave the valley was permitted out ii May. This was from cold-storage plants. Railroad reports for the se;ason!
show 4,572 solid carloads of fruit and 38 carloads of mixed fruit and vgvt;oble leaving the valley. These rail shipments show on our records as 4,671, eqluivalent car lots. The base used in computin- equivalent car lots was 372 boxes, 575 bushels, or 30,600 pounds in sacks. The increase in equivalent car lots over actual carloads was due in large part to the fact that fruit shplnents in sacks averaged considerably higher than 30,600 pounds to the carload. A total of
17,699 permits for shipment of fruit by truck were issued during thle season, or 2,801 equivalent car lots. Shipments by express are estimated at 100 (Uuivalent car lots. This makes a grand total for the season of 7,571 equivalent car lots.
During the shipping season of 1934-35 the new 100-pound box was introduced to the trade, 5 carloads of fruit being packed in such containers. A, new bushel box was also used to a small extent. The 10-pound sack was popular during the holiday period, 15,644 of such containers being used. The use of sacks for containers increased greatly during the season, 15 percent of the crop being moved in such containers, as compared to 0.5 percent the previous season. Of the total fruit shipped, oranges constituted 17 percent.

In order to enforce quarantine regulations, it is essential that motor vehicles be inspected when leaving the area. A road station is located on the main highway at the Brooks County line and this station passed 11,631 trucks from November to March, inclusive. These trucks carried 2,283.6 equivalent car lots of fruit. The average trucker is well aware of the regulations and, as. a result, only 9 trucks were turned back on account of not having correct. permits. Details of road-traffic inspection will be found in table 7; however, as the road station was open only from November through March, not all details of fruit movement by motor vehicles for the entire season are showi in this table.

sections were scouted for unlisted palms and 307 properties cheekvd f( volunteers. This conclud(les the eradication work in the Phoeinix istrict.
except for the final inspection of a few plantings of offshoots from previous, infested properties in the Coachella Valley and the Imperial Valley.
In the Yuma district 530 palms were inspected from ground and ladders and 16,173 from the ground only, and 139 offshoots were certified for movement. Leaf bases were removed from 97 previously infested plnms. 643 palns in th(e infested area were d(lug out and destroyed, 239 palms were pruned and offshoots destroyed, and 14 were pruned. No scale was found. This concludes the eradication work in the Yuma district, except for ladder inspection on 3 properties.

The area continuously infested by the Japanese beetle in 1934 was estimate, at 9,700 square miles, in the States of New Jersey. New York, Pennsylvania. Delaware, and Maryland. This is an increase of 900 square miles over 193:L No appreciable increase in the beetle population was found in the oldei infested area of New Jersey. The infestation has definitely increased in tlhe more recently infested counties in southern New Jersey and in nearly all of the infested sections of Pennsylvania. Delaware, and Maryland. A source o01 public complaint has been the number of beetles, dead and alive, washed ui on the shores of bathing beaches. A combination of favorablle winds and high temperatures at the time of maximum beetle flights resulted in e(i1ormi(ous
swarms of beetles being carried over the Delaware River and the Atlantic Ocean. This situation has been particularly annoying along the New Jers-ey
and Long Island coast beaches.
It has been found that larval populations develop faster in sod fiehls lun in cultivated fields. The average density of the larval populatioi in the heavily infested districts ranged from 13.7 in pastures to 2.3 per square loot in pumpkin fields. It is evident that the population is higher in fields pl iled! to crops, such as corn and asparagus, on which beetles feed readily, th: ii fields of tomatoes, potatoes, and pumpkins, which are only (occasi)in;lly attacked.
During the past two winters unusually lo,\v temjPeratures and heavy snailo occurred in the area of general infestation. ()\vin, to the p)resence of a heavy covering of Snow, the soil temperature was only slightly iiiluenced Ioy the cold. and there is no evidence that there was any imairke general reduction of the larval population.
Bacterial diseases, particularly the miilky disease which appears to develop at a temperature above 600 F., caused a noticeable reduction in the larval population during the spring of 1935; in limited areas in sonie localities al(ut one-fifth of the larvae were affected. The occurrenice of disease is, however. localized and subject to considerable fluctuation due i, variadle soil c(onlilions.


(C'nimirative t eI Nwere conducted under coitrollt The adult beetle causes considerable damage to roses in commercial greenhouses by emerging during the winter mouths and feeding on blooms. Tests during the season indicate that this damage an he prevented without injury to the plants by treating the beds with lead arsenate. Preliminary data indicate that ortiho-cliloro-phenol, cresol. limpid oil, and carbasota may be of considerable value as repellents for the Japanese beetle and thus afford protection to flowering shrubs in home gardens against injury by the hbetle.
In further study of the geraniol bait as an attractant for the Japanese beetle, it was found that none of the constituents of geraniol is more than 60 percent as attractive as the recommended combination of geraniol and eugenol. Phenyl ethyl alcohol added to the standard bait increased the attraction, but the Inerease in the cost of the bait for a comparatively small gain in the number of beetles caught does not appear to be warranted under general conditions. These studies have made it possible to prepare and recommend specifications for a cheaperr grade of geraniol for use in attracting the Japanese beetle. It has been definitely established that traps painted green and white are superior to traps painted with other colors. Public-service patents covering two types of Japanese beetle traps have been granted to F. W. Metzger.
I erris is a weak stomach poison but has a definite repellency for the adult Juilpanesc beetle, the repellent action appearing to be due to the rotenone and deguelin content. Exposure to light decreased the effectiveness of derris and the material was readily washed from foliage by rain. Several materials have been tested as stickers and as means to prevent the decomposition of derris in the field. Oils, while very effective stickers, have been found to accelerate the decomposition of derris when spread in a thin layer on the surface of the leaf. The emulsified residue from rosin stills has been found to be the cheapest and most effective sticker that does not accelerate the decomposition. The addition of magnesium silicate to the spray increased the period that the material is effective as a repellent. Derris without a sticker appeared to be of little value in the protection of early ripening apples from attack by the beetle. Derris with the sticker has given promising results. The derris spray has a disadvantage in that it is necessary to repeat the application every week to maintain goo(d control.
It has been known for several years that the application of hydrated lime afforded considerable protection to foliage from injury by the beetle, but the material was limited in Its usefulness on account of its poor adhesiveness. The addition of aluminum sulphate to the lime spray produced a residue on the foliage which Iasted through the summer. The use of this cheap, nontoxic repel lent spray offers considerable promise in commerci tal orchards and on 'rnaiimen tal trees and shrubs.

Considerable progress his been made in the coloilization of imported parasites of the Japanese beetle at a number of I)ints in the generally infested area. Tiphia vernali& Rohl. is now well established and increasing rapidly. In the spring of 1935, 141 colonies were placed in heavily infested areas in New Jersey, Pennsylvania, an(l Delaware, making a total of 493 colonies of this species in the field. T. popilliavora Roh. was defitely established in 1926 and has been extensively colonized; 185 colonies were placed in the field during this summer, bringing the total number of colonies to 379. This species shows more fluctuation in population from year to year than T. ernalis. Two colonies of the Korean strain of T. popitlavora, which appears in the field later than the Japanese type and is more nearly synchronized with the appearance of the third-instar larvae, were placed in the field, and sufficient material is available to place approximately 20 colonies of this parasite in the field during the coming year.

The Asiatic garden beetle (Autoserica castanea Arrow) has continued to spread westward on Long Island and in Westchester County, N. Y., in suburban areas immediately adjacent to Philadelphia, Pa., and throughout New Jersey. The injury caused by the grubs to vegetable seedlings was marked late in the spring and early in the summer. A large number of complaints were received from restaurants, drug stores, and baseball parks and other places of amusement which operate at night and use large flood lights, because the beetles were attracted to the lights in such enormous numbers that they became a nuisance and curtailed business activities.
It has been found that rose geranium oil, eugenol, and tansy oil are defnitely attractive to this beetle, indicating the possibilities of using these materials to increase the capture of the beetles in the light traps. Two types of traps and lights were tested, and on favorable nights as many as 2,000 beetles per trap were captured in a single hour. Tests during the summer indicate that this beetle can be controlled in vegetable gardens by the use of ai poisoned bait containing bran, lead arsenate, molasses, and water.
Tiphia asericae A. and J., a Chosenese parasite of the Asiatic garden beetle, which was liberated in previous years in the vicinity of Philadelphia, in northern New Jersey, and on Long Island, has been recovered in these localities.
The status of the oriental beetle (Anomala orientalis Waterh.) is about the same as in 1934, the spread of this species being relatively slight. Some injury has been observed in lawns and gardens but much less than is caused by the Asiatic garden beetle.



For the first year since the original quarantine on account of the Japanese beetle was issued in 1919 it was not considered necessary to extend the territory under regulation. Only three first-record finds of major importance-at St. Louis, Mo., Chicago, Ill., and Indianapolis, Ind.-were recorded during the 1934 trapping season. The most outstanding find at a point remote from the central infested area was that disclosed at St. Louis, where beetles were collected in such numbers as to indicate an established infestation. At Indianapolis 17 beetles were caught in a residential section at some distance from a railroad line. This infestation probably resulted from illegal transportation of infested plant material. The locations at which were trapped 6 beetles in Chicago and 1 beetle in East St. Louis, Ill., point to the probability that these adults had been transported by rail from the heavily infested sections of New Jersey or Pennsylvania.
With limited funds available for determining the spread of the insect, trapping was confined to those States immediately adjacent to known infested territory. Supplementing trap surveys in nonregulated territory in Maine, New York, Pennsylvania, Ohio, West Virginia, Virginia, and Maryland, traps were operated to check previously determined infestations in Det roit, Mich., St. Louis, Mo., and Greenville, S. C., and to determine presence of the insect in Chicago and East St. Louis, Ill., and a few selected cities in Indiana. The season's trapping program began in Virginia on June 18. Trap distribution progressed northward following the dates of probable beetle emergence. The latest traps set were those placed in Maine. Except in cities where continued

of $268,663 on 77,611 acres, or an average per acre damage of $3.46. There are in Cumberland County 330,080 acres, 51,087 of which are in iiiarshli land. As the county is priniarily agricultural, there are in it approximately 278,993 tillable acres. Figured at the average damage per acre, county-wide damage f $965,316 is estimated. Irrespective of possible factors that might reduce this estimate, it is apparent that Japanese beetle damage is an important factor in the cost of producing farm commodities in this southern New Jersey county. From an analysis of the collected data, it is the conclusion of the Cumberlaind County planning engineer that concentration of the infestation in the vicinity of Shiloh is due chiefly to the inability of the beetles to cross Delaware Bay, thus resulting in a piling up of the insect in that section. A similar survey was made as an Emergency Relief Administration project in the adjoining county of Gloucester, but data collected were not made available to the Bureau.
In heavily infested agricultural sections in southern New Jersey, sections that for years have been subject to intensive beetle damage are still holding their maximum populations. For 3 consecutive years early maturing apples in certain orchards have been rendered unsalable by beetle feeding. In the Philadelphia water-front district the heavy flight of the adult expected in 1933 did not occur. In the summer of 1934 the insect resumed its heavy flight in the wharf and market districts, contradicting previous indications that the population might have decreased permanently. The adult flight in Philadelphia lasted for nearly 5 weeks, from July 11 to August 13.
Beetle feeding in one block of 1,200 Yellow Transparent apples located in southern New Jersey was responsible for almost complete destruction of the crop. In 1933, 3,600 bushels were harvested from the orchard. Only 36 bushels could be picked in 1934. Other severe commercial damage was evident throughout the densely infested sections.
Flotations of adult beetles in Delaware Bay, Raritan Bay, and the Atlantic Ocean were again observed, but not to the same extent as in 1933. The flotation from New Jersey to the Delaware shore on Delaware Bay was most pronounced in mid-July. Beetles were washed up on the beaches of Long Island on August 10.
Although Waterville, Maine, was included within the regulated zone as an extension of territory resulting from the spread determined in 1933, trapping was repeated there again in 1934 to learn whether the record-breaking subzero weather between the two seasons had killed off the overwintering grub population. Instead of 204 traps being operated for 30 days, as in 1933. this year 300 traps were set for 40 d(lays; and, whereas last year 139 beetles were trapped, this year's capture increased to 299. Apparently the soil temperature at a depth of 6 inches or more did not decline sufficiently to affect larval survival.

Another progressive reduction in the number of beetles captured in Erie, Pa., was recorded as a result of trapping in that city. A total of 1,427 traps wvas il operation from July 6 to September 8. This was the largest concentration of traps ever set in the city. Successive years' captures in Erie have been: 1931, 171; 1932, 282; 1933, 167; and 1934, 114. Of the 1934 total, 43 specimens were survivors of infestations discovered in 1930 and first treated in the fall of t year. Most of the remainder represents spread not previously determined. The significant feature of the control work in Erie is that intensive trapping in the older infested section of over 44 acres, where the soil has been poisoned for a period of 2 or more years, disclosed only 3 beetles Approximately 2,600 traps were set from June 19 to August 25, 1934, in the sections of St. Louis, 1Mo., believed most likely to be infected. witl the resultingi capture of 1,351 beetles. Funds were made available by Exectitive order t i.ot enabled the Bureau to apply lead arsenate to all sections of tlhe city where bee iles had been caught.

Salem, Ohio. Examination of soil accompanying a single flowering plant being moved from Ihliladelphia, Pa., to Inkster, Mich., resulted in collection of 12 larvae. From numerous larvae taken from soil about the roots of 2 zinnias, 9 pansy plants, and 1 ivy plant being transported from Westtown, Pa., to Chautauqua. N. Y., there were identified 9 Japanese beetle grubs. Nine larvae were taken from SQil about the roots of two evergreens found ill the possession of a motorist traveling from Woodstown, N. J., o Carmel, ind. One of the summer interceptions consisted of nine adults taken from the cab of a truck en route from Lime Rock, Pa., to Woodstock, Va. All suspected larvae intercepted by road patrolmen are forwarded to field headquarters for identification.
Among nursery stock surrendered at the road stations were 130 lots of five-leafed pines seized while being transported in violation of Quarantine No. 63.
Inspection of small lots of plants and farn products by road inspectors was continued. The practice of removing uncertified soil and replacing it with fumigated soil on hand at the posts has met with very favorable public response and has materially reduced the frequent complaints that formerly were received from drivers who were obliged to surrender their products or return to a designated center for inspection and certification.
Motor vehicles stopped for inspection at the road stations during the year numbered 2,455,072. Of the cars and trucks examined, 16,695 were found to be transporting uninspected quarantined products.


Nursery and greenhouse scouting in the summer of 1934 resulted in the ending of adult beetles on a larger number of theretofore uninfested premises than were determined as infested in 1933. Infestations were found for the first time on 64 classified establishments, as compared with first-record finds on 33 such premises the preceding summer. Beetles have been found on the premises of 80 percent of the 363 classified establishments in New Jersey. This condition is largely a result of natural spread of the insect. Amon2,241 nurseries and gTeenhouses fulfilling the quarantine requirements for classification, 555 are infested and the owners are obliged to grow their stock in screened greenhouses, free it from soil, or chemically treat it before shipping to noninfested territory. This is a net decrease of 135 in the number of establishments on the classified list. There was a large reduction in infested classified establishments, many of which relinquished their classified status rather than conform to the conditions necessary for keeping their stock free from beetle infestation.
Spring demands for inspection and certification of nursery stock were consistently heavy in all States under regulation. A numb er of shippers that had been inactive for the past 3 years suddenly began shipping, with a consequent need for detailed examination of plant material from an unexpected source. This required that additional inspectors be hired to supplement the regular inspection force.
Soil samples collected from nursery plots treated with lead arsenfite were submitted to the Japanese beetle research laboratory for analyses. For the purpose of determining the present toxicity of poisoned nursery plots. 873 samples were collected during April and the early part of May. Results of the analyses were available in time to permit nurseries to restore their treated sections to the required dosage of 1,504) pounds of the soil insecticide per acre by the dates prescribed in the treating instructions. A total of 76.7 acres, containing 362,048 items of growing nursery stock, is involved in the poisoned areas treated during the year. This acreage includes plots newly treated, those re-treated and brought back to their orig-inal dosage, and plots found upon analyses to have carried over a sufficient concentration of the lead arsenate. Seventeen tons of powdered lead arsenate were distributed on nursery plots by the owners in completing initial treatments and re-treatments. Some 1,200 pounds of this amount was applied to 94,4("3 square feet of heeling-in areas and coldframes.
Cooperative experiments with the Japanese beetle research laboratory resuilted in the adoption of a treatment whereby certain species of azalea may be rid of Japanese beetle infestation by means of paradichlorobenzene fumi-ation. Interested nurseries furnished plants used in the tests, and were very anxious to have such a method approve. This new method permits certification of types of plants that are not tolerant to the commonly employed chemical

emergence of the insect, densely infested with the beetle. As a condition of certification of fruits and vegetables, other than onions and potatoes moving via refrigerator car from the zone of flight, there are required inspection and loading in a manner to prevent infestation, in a refrigerator car with closed or adequately screened doors and hatches, which car prior to loading has been dktermined by an inspector as thoroughly swept and cleaned by the common carrier in a manner to rid it of infestation. During the interval between cleaning and loading the car must be kept tightly closed and sealed. Fumigation, when deemed necessary by the conditions of beetle flight, is required in the case of onions and potatoes moving via refrigerator car from the same sections. No change in regulated area was involved in this revision of the regulations.
Tests were necessary to devise a method of fumigating refrigerator (ars containing potatoes and onions shipped from heavily infested sections while the insect is in active flight. As finally devised, the equipment to be used consists of a pressure cylinder of liquid hydrocyanic acid with an applicator. By testing tips with various-sized holes, it was finally determined that one with a hole 0.002 inch in diameter would deliver 6 ounces of hydrocyanic acid in 1 minute under a pressure of 30 pounds. In practice the loaded refrigerator cars will be tightly closed, except for a narrow opening in one door through which a nozzle 3 feet long may be inserted. After discharge of the gas for 1 minute, the door is closed and the car sealed for a 2-hour fumigation period. Since adult beetles did not emerge during June in numbers sufficient to constitute a flight, this fumigation procedure was not employed during the present fiscal year.
Activities incident to the seasonal quarantine on fruits, vegetables, and cut flowers were fully organized on July 1, 1934. Inspectors were stationed at 37 inspection centers located at important shipping points throughout the regulated area. South-bound and west-bound trucks transporting fruits and vegetables from the heavily infested sections were required to report for inspection at platforms in Fredericksburg, Va., and Pittsburgh, Pa., respectively. This designation of inspection centers was occasioned by the fact that motor vehicles transporting certified products become infested with the flying beetles as the trucks proceed through the flight zone. With the scene of inspection transferred to a nonflight section, there were no such opportunities for reinfestation.
In the course of the fiscal year a total of 484,427 certificates of all kinds were issued to cover products affected exclusively by the Japanese beetle quarantine.
Table 9 shows the quarantined articles intended for shipment from the regulated area and for use in certified greenhouses, or surface soil in nursery plots, heeling-in, or plunging areas, which were fumigated or sterilized during the 12-month period.

These included interceptions by transit inspectors of the bureau stationed at Ipostal and comnimon-carrier terminals an;d by highway inspectors extidnitig roa( vehicles. In tie course of the year prosecutions were successfully terminated in the United Stales district courts against 2 individual and 3 corporate violators.
Following transfer on September 10, 1934, of supervision of Dutch elm disease eradication work to L. H. Worthley, field headquarters of the Bureau directing Japanese beetle quarantine enforcement was removed in November from Harrisburg, Pa., to White Plains, N. Y. The new field headquarters is strategically situated in the areas jointly affected by the Japanese beetle, Dutch elm disease, and European corn borer, and is conveniently located near the gypsy moth infested zone.
Four Canadian officials attended a tour of the heavily infested southern New Jersey territory on July 16, 1934, and the Syracuse, N. Y., district supervisor made field observations on the Niagara peninsular district with the Canadian officials preliminary to their 1934 trapping program. Cooperation was again accorded the Canadian Department of Agriculture in purchasing 500 Japanese beetle traps from a Philadelphia manufacturer.
Limited numbers of traps were operated for control purposes under State or municipal auspices in Delaware, Connecticut, Maryland, New Jersey, Rhode Island, and Massachusetts.
State appropriations were available for Japanese beetle quarantine or control operations in Connecticut, Delaware, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Rhode Island, and Virginia. Trapping operations in Maine, Indiana, Michigan, and Missouri were financed from funds allotted by the respective States or cities in which the work was performed.

As in the past, one of the most important activities of the Division of Forest Insect Investigations has continued to be the cooperative service rendered to tle several Federal agencies administering timberlands, such as the Forest Service, National Park Service, and Bureau of Indian Affairs. as well as to such emergency agencies as the Civilian Conservation Corps, the conservation program of the National Recovery Administration, and the shlelterbelt program. IPrivate owners have also been aided, but to a lesser degree. This cooperative service, for the most part, consists in surveys of bark beetle infestation, estimates of loss, recommendations as to methods of control, estimates of the cost of such operations, and technical direction of control projects. It might he added that such dutiess have more than doubled within the last few years, owing to the increased activity in forest-insect control in connection with emergency activities.
In California the epidemic of the mountain pine beetle which started in the Yosemite National Park and Uladjacent forests in 1931 and took a heavy toll of the fine sugar pine has been brought under control. (Other projects against the same beetle in lodgepole pine stands in Crater Lake and Mount Rainier National Parks have been entirely successful. In the Itcky Mountain region the mountain pine beetle still continues its alarming destruction in some areas, while in others it is on the wne. n the 'ocur dAlene and Kootenni National Forests the control efforts begun in 1930 have resulted in the preservation of the valuable cnImlnercial white pine stands.



Encouraged by the results secured in recent years from well-planned extensive control operations the Forest Service, Park Service, Bureau of Indian Affairs, and private timber owners have been especially active during the last year in the control of the western pine beetle. In Oregon and Washington over 250,00YJ acres of pine timberland were covered with control work. A similar enthusiasm among bothi public and private protective agencies is also evident in California. In northern California the McCloud River Lumber Co. has committed itself to, the policy of cutting and milling infested trees and destroying the infested bark. Although the timber thus salvaged contains considerable blue stain, there is a market for it, and from the standpoint of cost this method is much more advantageous than the wasteful one of burning the infested bark and leaving tie logs to rot in the forests.

Control operations against the Black Hills beetle in several forests in Colorado, against the Douglas fir beetle in Wyoming, and minor operations against threatening infestations of several species of Ip8 in a number of localities have also been carried through.

Research work directed toward the development of more efficient and economical control methods against bark beetles has been continued, and in some cases slight modifications of previously used methods have led to excellent results. One such modification is based on the principle of preserving a larger percentage of the natural enemies of the mountain pine beetle, to bring about not only a numerical reduction of the pest but also a more favorable relation between parasite and host, thus assuring more lasting benefit from the control operation. Encouraging results have continued from experiments in killing bark beetles by means of penetrating oils applied to the bark and by the introduction of lethal materials in the sap stream of infested trees, but the methods are not yet sufficiently perfected to warrant their use in large-scale control projects.
The continued demand for nursery stock due to the remarkable activity of the reforestation program in connection with the Forest Service and with the various emergency activities, such as the erosion control work, the shelterbelt program, the Civilian Conservation Corps work, etc., has made the control of insects affecting forest nursery stock and newly established plantations of vital importance. Of the numerous insects important in these connections, the white grubs are by all odds the most destructive. A thorough investigation of these insects is under way, involving not only a study of their biologies, but also the development of control mnethiods which will kill the grubs but will not injure the young trees. The nursery work is largely centered in the Southeastern States, while the work in plantations is centered in the Lake States.
The investigations on the locust borer in the Central States were continued along the line of preserving stands by means of stimulating new growth of trees from sprout growth following cutting of the badly infested trees and by mulching. The projects on the southern pine beetle, the white pine weevil, the beech coccus, the larch case bearer, the leaf-mining sawfly, the elm leaf beetle, and other native and introduced insect pests of trees in the East have also been considerably advanced. An extensive survey of the New England States to determine the occurrence of the balsam bark louse was made, and experiments in control, applicable to infested balsam trees used as ornamentals, were successfully conducted.
The work upon the insects associatedl with the Dutch elm disease has been greatly enlarged by the transfer of seven men to the Morristown, N. J., laboratory from the old Melrose Highlands, Mass.z., laboratory, and the employment of additional men on emergency funds. During the year a great amount of biological work has been done upon various insects found in elm, and much experimental work performed to determine insect vectors, with special reference to those which injure the bark either in feeding, ovipositing, or in the construction of brood burrows. During the year, as a result of field, laboratory, and greenhouse experiments, 50 cases of successful transmission of Cera to8to'mclla ulmi by the smaller European elm hark beetle (S3colytns inultisria-

Island. All of these shipments were free from infestation, except aL single lot of cordwood on which one egg cluster was, found. A limited amount of checking work was performed in a number of areas that had been scouted by the State force but no additional infestation was discovered.

In the area between the barrier zone and the Connecticut River, work has been carried on throughout the year by men allotted from 18 Civilian Conservation Corps camps. In most cases 20 men have been detailed from each Camp for this work, which is carried on under the supervision of the gypsy moth office of the Bureau of Entomology and Plant Quarantine. One forest camp is located in Vermont, 5 in Massachusetts, and 7 in Connecticut, and, in addition to these, 5 camps under the control of the Department of the Interior are located in the Massachusetts area. This work is a continuation of that taken up during the previous fiscal year.
The average number of Civilian Conservation Corps men on the gypsy moth work on days when work was performed was 428. Owing to arrangements allowing for the making up of 1oA time on Saturdays, only 1.1 percent of available time was lost. This is a mal-rked improvement over the record oif the previous year, when 15 pereent of available time was lost. During the year 103,445 0-hour man-days were used on the project, being some 26,000 more man-days than during the previous year. This increase in man-days made possible a large increase in the volume of work accomplished, especially hand control practices in severe infestations. The tree growth on a total of 407,053 acres of woodland and open country and along 1,441 miles of road was examined for gypsy moth infestation. This is slightly less than was accomplished the previous year, owing to the more intensive work done in infestations. Tabulations of the year's work show a large increase in accomplishments, with nearly a million individual trees examined and 4,685 destroyed. Fallen trees and branches and undesirable tree growth, also species particularly favored by the gypsy moth, were removed from 984 acres, leaving these stands less favorable for gypsy moth increase, and in better condition for future gypsy moth work. A total of 612,069 new egg clusters were found and treated. During May and June 1935, 396,933 trees were banded with burlap, and by the end of June 1,388,430 gypsy m-oth caterpillars were destroyed by men patrolling them. This type of work is seasonal and many more caterpillars will be crushed in July before the season is over.
The work has demonstrated the practicability of using Civilian Conservation Corps men for gypsy moth work in the area under consideration and has resulted in preventing large increases in the gypsy moth infestations in the area worked between the Connecticut River and the barrier zone and has materially decreased the danger of spread from this area into the zone.
During the year a large extension of the Civilian Conservation Corps gypsy moth work east of the barrier zone was proposed and, if put into operation, it will probably result in greatly extending this work for the coming year, although not to the extent requested.


On the northern rim of the area that was previously infested. in New Jersey. several male moths were taken in the summer of 1934, in tile townships of Mendham, Morris, and Randolph, and a single moth was captured in Pahaquarry Township near the Pennsylvania line. The State gypsy moth force carried on scouting work in the fall and winter in the first three towniships and Federal agents were detailed to work in Pahaquarry Township and toscu certain sections in the townships previously mentionedI near someC of the ca ,,s, where male moths hadl been captured the prev-ious summer. Iii all. 3,0312 Icres of woodland were scouted and, in adIdition to thiis., 532 acres in the region of the Palisades near the George WahntnBi-id.- Fort Lee, N. J., were scouted by tile State force. No infest ation was- found in Pahaquarry Towvnship, but two locations, totaling 31. egg clusters. Nvere discovered, in Morris Township, and one consisting of 14 egg clusters was foud onl the Mteuidl.1aRandolph Township line. These areas were sprayed inl JIune and aI beltsu' rounding them, aggregating 1178 acres, was also treated. The State and Federal forces cooperated in calinyiuig through this work.



With the Federail and State finds available in the Pennsylvania area and tie assistaillPe from Llzet-lie a1nd Lak aal l 'lnlies previously referred to, it wais found possible to scout intensively flood arels with in the infested terrt ory lonig the Susquehi1 lanna Rvrd LackaVa II t :I usssemnbl ing-cage sites
weril m ll I moths were ap ured last Slmr111If, I S of previously loc fed infestations in outside territ ory, and to d( considerable scouting and (rejsoting in tihe generally inifested area. Woodland areas were thinned and the slash was burnled in sectiolls W1e0re effeclive scouting could not otherwise be done, proll Were relloved froll stulDps in territory preViously clt over, and the 11t dangerous areas were sprayed during May id June. Burlap hands were also applied in woodland and residential sections vhere considerable infsit tion exists. These burlaps were patrolled and all caterpil ar< found were destroyed.
In a total of 70 infestations found during the fiscal year 1934 in 15 lightly infested townships, only 10 were reinfested in 1935, and 5 of these were in localities where only single egg clusters were found during 1934 awl where no spraying was done. In the other 5 the trees along the property lines were not sprayed because wind drift would have caused the spray to lodge in adjoining property not covered by permits.
During the year 8,698 shipments of quarantined forest products, nursery stock, and other materials were inspected and a total of 70 gypsy moth egg clusters were found and treated. There were a few quarantine volat ions, and in anch of the cases prosecuted by the State the defendants were found guilty.

Fronm the latter part of January to the last of April, special survey work was carried on with negative results west of the Hudson River in the extreme 'soutlieastern part of New York, in northeastern Pennsylvania adjacent to the New York and New Jersey State lines and the area where regular scouting work has been performed, in sections of northeastern and southern New Jersey where no scouting or cage work had previously been done, in New Castle County, Del., and in three townships in Cecil County, 'Md. The State authorities in these States and in Ohio were urged to do as much special survey work as time and funds would permit in territory where Federal work was not planned. Fifteen Federal experts were detailed to this work. They paid particular attention to trees and nursery plantings on large estates, around hotels, gasoline stations, cemeteries, and dumps; also in localities where large movable equipient used in construction work might have been used or stored. Although an average of not more than 4 days was spent in each town, the work was sufficiently well done so that it is believed any sizable infestation would have been noticed. The State of New Jersey furnished an inspector who worked with the Federal employee assigned to duty in that State. Pennsylvania and Ohio also dil considerable work of this type. No infestation was found in any of the outlying territory.

DIuring the spraying season more than 7.701) acres of woodland and 6.30I resident iail properties were treated in the Pennsylvania territory, and the other a -rs are Indicated under the States concerned. This involved the use of G1
high-power spraying machines in the following States: Mussachuwtts. 11 : Contelicut, 12: Pennsylvania, 27: -New Jersey, 2. In :addition to these, 9 sprayers were loaed to the conservation department of the State of New York for ir ating infestations on Long Island, in the Bronx. and in Austerlitz and Milan In the barrier zone.
The weather during the spraying season was not so favorable as usual and UoJll erTHileI fillne wals lost oil ce1 ti111 of raill a[11ll wet folialgo.
Assembly ing-cage work was conluceted in ermuout, Massachusetts, Connect i\i\0 ,ilnd Pelinsylvania.

In the summer of 1934 defuldution mused by the eypsy moth was considerably il exlc5s of that recolded for 193. For the entire infested area total of 19.3(11 ne of woodlnTil with fron slight to complete defoliation were found, Is cmarel with :197) :arrow rtcom al fr 19. Illgnl there was less


defoliation in the eastern part of the infested area than had been recorded in the several years immediately preceding. This was particularly true as to Barnstable and Plymouth Counties in Massachusetts. Bleyt nd these sections the amount of defoliation increased considerably, particularly in New Hampshire, westward to the Connecticut River, and in Massachusetts from the central part of Worcester County to and beyond the above-named river. The records for the summer of 1934 showed that there was considerable increase in defoliation for Maine and New Hampshire. Massachusetts showed some decrease, owing principally to a decided decreasee in the southeastern part of the State, which was not offset by a large increase farther west. There was a decided increase in the amount of defoliation in Rhode Island.


Beginning about the middle of January 1935 an extended series of observations on the extent of gypsy moth infestation and damage caused to woodland was begun in several towns in the eastern part of Franklin County and the northwestern part of W'orcester County, Mass. The purpose was to obtain accurate records of the degree of infestation, the types of growth, the natural conditions of the infested areas. and the amount of injury caused by defoliation. Areas were selected for which records of degree of defoliation in 1934 were available. One area was selected in Athol, 3 in Orange. 4 in Erving, and 8 in New Salem. Mass. This work has been under way for such a short time that it is hardly possible to draw very definite conclusions with respect to the effect of defoliation on all species of trees. It has been definitely established, however, that one complete defoliation is sufficient to kill hemlock. for in the Athol point 38 out of a total of 42 large trees of this species, ranging up to 55 feet in height, were killed by being completely defoliated in the summer of 1934. The other 4 trees in this group were not completely defoliated and still show signs of life. With respect to white pine, a section of the same point in Athol has quite a stand of small pines averaging about 5 or 6 feet in height. A count showed that one-sixteenth acre of this area contained 94 small pines. All of these were heavily defoliated in 1934. and at present 25 percent are dead and the remainder are in very poor condition. In all of the areas where white pines were selected within sections that were defoliated, these trees suffered injury. depending on the degree to which they were eaten. If they were completely defoliated they were killed. At a hillside location in Athol 42 pines ranging in height from 30 to 35 feet have died as the result of complete defoliation in 1934. Most of these pines attempted to refoliate after being stripped of their needles. Last winter they were more or less covered with the short. undeveloped new needles, but since then they have turned brown and are dead. For all of the 16 acres in which records are being taken the proportion of growth favored by the gypsy moth is rather high. In general, the growth most desirable for gypsy moth foo( consists in the main of white, red. black. and chestnut oaks, poplar, and gray birth. By actual and careful checks of the areas, which range in size from 2 or 3 up to 50 acres, these favored food plants comprise from 30 to 95 percent of the entire growth, the general average being between 60 and 70 percent. White pine and hemlock, which have been eaten so heavily, comprise from 5 to 60 percent of the woodland growth, the average probably being about 20 percent. The remaining growth, which might be considered only partially or not at all favored, consists of paler birch and red maple, with a scattering of other species. It can be seen, therefore, that for most of the area where the records are heinz taken the crowlth is. in the main. exremely desir:ble to this insect, and this fact is attested by the extent of defoliation that I:is taken place in those areas.

In general, there was a light-to-medium infestation of this species throuchout practically all of the infested territory, but no instances of appreciable defoliation were reported during the summer of 198,4. during the winter of 1934-35 numbers of winter webs were cut by the States in Maine, New Ilampshire, and Vermont. For Maine only partial records are available, and this work was performed by men from three Civilian Conservation Corps camps. A total of 72.819 vwebs were cut and destroyed in 23 towniis located mostly in the southern part of the State. In New IHampshire webs were cut in towns throughout the greater part of the infested area. A total of 1.548.27 welbs

The scouted lots, totaling approximately 10,000 acres, were located in tie
lightly infested gypsy moth area of western Massachusetts and southern
Vermont. All inspections gave negative results. A total of 30,700 bales of
boughs was certified for movement from these lots.
The quantities of articles of the respective quarantined products certified during the fiscal year are summarized in tables 10 to 13. The number of gypsy moth egg clusters removed from inspected products showed a 350-percent

survey, infestations had been found in seven towns in which the moth was not previously known to exist. One of the new infestations is in southeastern Connecticut, 2 are in New Hampshire, and 4 are in Maine.
Within the infested section, satin moths were noticed depositing egg masses at Concord, N. H., as early as June 6. In northeastern Maine moths were found ovipositing as late as August 2. District inspectors in New Hampshire and Maine observed very little satin moth feeding, as compared with the 1933 defoliation. In some localities where large numbers of hibernating larvae were noted in the fall of 1933 there were no signs of feeding in the summer of 1934. Satin moth egg clusters were not as numerous in the quarantined zone as they were in the summer of 1933.
By arrangement with the Division of Foreign Plant Quarantines, an inspector from the port inspection office at Seattle, Wash., was detailed from July 22 to August 12 to scout a tier of counties in central Washington east of the area in the State designated as satin moth regulated area. Observations were confined to black cottonwoods and willows, the host trees of the insect in the Pacific Northwest. Three weeks' scouting in Klickitat, Yakima, Kittitas, Chelan, and Okanogan Counties gave negative results.

At the outset of the fiscal year elm trees confirmed as infected with the Dutch elm disease (Ceratostomnella ulni (Schwartz) Buisman) numbered 2,012 in New Jersey, 8 in Connecticut, and 1,235 in New York. This total of 3,255 diseased trees had been discovered as a result of scouting operations carried on in a tri-State area of 1,400 square miles since the disease was first detected at Maplewood, N. J., in June 1933.
Systematic scouting, already under way for several weeks on July 1, 1934, continued until the end of August, when reduced funds necessitated dismissal of Federal scouts. Scouting was continued in New York with men employed on State funds until brisk autumn winds in October defoliated the elms and forced abandonment of foliage scouting for the season. Before discontinuance of summer scouting, all of the originally known infected area in New Jersey and Connecticut had been surveyed twice, and the New York State scouts had finished a partial third survey. Discovery of infection at points near the margiiA of the infected zone required several extensions of the 10-mile protective zone included as an additional work area circumscribing the known infections. It was principally in these extensions that scouting was hurried and incomplete.
Definite and severe wilting of elm foliage, later confirmed as Dutch elm disease infection, was first oh'served during th summer of 1935 in the Bronx. New York, N. Y., on May 16. Systematic scouting from that date to the end of June resulted in the finding of 904 additional cases of infection, 559 located in New Jersey, 341 in New York, and 4 in Connecticut.
Discoveries of infected elms at points beyond the previously known diseased area were made during July, August, and September 1934 at 6 points in New York, 4 locations in New Jersey, and 3 towns in Connecticut. New Jersey finds were made 3 miles north of Hopewell in Montgomery Township, Soimerset County; at Petersburg, in Morris County; at Echo Lake, in Passaic County: and at Princeton, in Mercer County. The most remote infections found in New York during 1934 were at Katonah, Cross River, and Crugers, in WVstchester County; Stony Point and Sloatsburg, in Rockland County: and just west of the Suffolk-Nassau County line near the village of Central Park on Long Island. Contiguous to the 193: known infected zone in Connecti'iit, new infections were found in Norwalk and about 4 miles north of the village of Fairfield, both points in Fairfield County.
New finds at points isolated from the tri-State zone of infection comprised 1 infected tree in Old Lyme, New London County, Conn., 4 in Indianapolis, Ind., and 1 in Norfolk, Va. As a result of 1934 scouting in Cleveland, Ohio, where the disease was found in 1930. 1931, and 1933, two additional infected trees were removed.
Included in the tri-State infected zone at the end of the fiscal year was a total of 2,478 square miles. of which 1,402 square miles were in New Jersey,

Eradication crews organ-ill izedl under the allotment of P. W. A. funds available late in Decembher soon reduced the number of infected trees as the sanitation work progressed through(lut the affected territory. By February 2 the few remaining infected trees in C'onnecticut had been felled and burned. New York was entirely free froml standing infected elmis by March 30. In Newv Jersey, all1 clii trees- that could be confirmed by laboratory diagnosis were eradicated lby April 15.

in Connecticut and New Jersey felling and burning of diseased trees was taken over as a Federal activity with the inauguration of the Bureau's sanitation program in January.
Finances to carry on scouting and eradication were obtained from a variety of sources. Available at the beginning of the fiscal year was a regular Bureau appropriation of $150,000 and an allotment of $6,000 from the National Recovery Administration. On December 21, 1934, a tund of $667,000 was allotted to this work by the Public Works Administration. As the regular appropriation bill contained a clause providing that the Dutch elm disease appropriation could not be augmented by emergency funds of Federal origin without reimbursing the Treasury for the amount so added to the regular appropriation, up to the total of that appropriation, the emergency funds actually expended amounted to $527,000. These emergency funds were exhausted in May 1935. On May 28, an allotment of $250,000 was approved from work-relief funds. Reorganization of the project on a work-relief basis was in progress at the end of the fiscal year.
State appropriations of $30,000 each were available at the beginning of the fiscal year in New Jersey and New York. In August 1934 an additional New York appropriation of $142,500 for Dutch elm disease control work became available. New Jersey funds were largely exhausted by the middle of August 1934, and not until the following June were further New Jersey funds allotted to Dutch elm disease eradication. On June S a State emergency appropriation of $25,000 became available in New Jersey for scouting and eradication activities. Several Connecticut garden clubs cooperated in employing scouts to survey their respective towns.
When emergency funds allw:ted by the Public Works Administration became available on December 28, 1934, it was possible to build up an organization capable of quickly eradicating all standing, infected trees, aInd in addition make heavy inroads on dead and dying elms existing in the major diseased section. Decision to remove the latter type of trees was justified by the fact that they constitute potential sources of infection or are possible breeding places for the known vectors of the disease. Under conditions prescribed for employment on public-works funds, suitable men were selected from among those registered at the offices of the National Reemployment Service in the counties where the work was performed. As many experienced tree surgeons and tree climbers were unemployed during the winter, an efficient corps of workers was assembled. By the end of Janu:ary 791 temporary men h'ad been employed. Workers paid from emergency funds reached a maximuum of 1,174 just prior to dismissal of the sani: ation force on May 10 because of lack of funds. With disbandment of the crews, most of the Federal sanitation work was discontinued until reorgnization of the work on a relief basis was begun in June 1935. The State of New York assisted in this work by taking over 144 eradication-crew members for 10 days, s parting May 25. In furtherance of this work luring Federal inactivity, an emergency New Jersey appropriation was available on June 8 for the employment for a period of 3 weeks of twenty-five 6-man eradication crews and fifty 2-man scout crews.
By the end of the fiscal year, sco uts had tagged some 690,00,0 (lefd or (lying trees, with the additional marking for (les: ruction of 335.000 misuel!:'nlous elm units, comprising stumps, slash, logs, and fuel woo'd. Vhn,. eradiation crews were operating at capacity in Mirch and April their weekly production frequently exceeded 20,001) trees and 14,000 miscellaneous units. In the coi:rse of the 4,, months' intonsive sanitation prograin eradication cr(ws removed )r destroyed approxiiia.tely 460,000 dea(l and (ying trees and 160,000 stumps or other miscellaneous units. This left at the end (if the fi (al year a residue still marked for destruction of 230,000 Irees and 175,000 other elm units.
Men assigned by the Civilian Conservaton Corps to IDuch elm disease eradication under the supervision of Bureau employees wore a major factor in much of the elm-sanitation work pert')rmedl in woodland areas. At the end of the year approval had beenIi granted for the construction of 3 Civilian Conservation Corps camps in New Jersey, 2 in New York, and I in C('nnecticut. When fully organized, these camps will be devoted exclusively to Dutch elm disease control activities.
Coordination and active direction of the work were supplied by a skeleton force of federally appointed men. This reached a maximum of 179 at the

InI 01he West a new pine infection c-nter was iccatedl oii Steamlboat Creek, Doug"las County, Oreg-.. about 1,00 miles from Calif orniia, but scout ita., ill the sugar pine forests of northern California failed to reveal thepeec of the(rust. In the western white pil( re gion of northeastern Washington, nlorthiernt Idaho and northwestern Montana. 89 new centers of pine infection wveroe rePorted, making, a total of 129 for tlte region. All of these, have developed within the last 12 years and there are undoubtedly many others still undiscovered. Of the 39 newv centers, 8 were inl northern Idaho and northeastern Wa1shington onl the Kanlksu National Forest, 1 on the Lilo National Forest. and 4 on the Cabinet -National Forest in Montana. This is the first record' of pine infection in Montana and in these national-fo-rcst units.
Careful inspection and study of white pine areaS shiow that very LU tle new infection is occurring onl white pines in the areas thatt hiave been broughIt under control by the eradlication of Ribcs, but in similar unpilrotected areas, the rust is increasing rapidly and causing, serious losses in whlite pine Stand:.Z. particularly among the younger age classes. This steady spread and iiuten'4-illcaiion 01 the rust in"unprotected areas is indicative of the need for vigorous and coiitinuous application of control measures to protect the valuable white pine forests of this country.
Since the European or cultivated black currant (ffib(s S ujyrum) is. iore sus'ceptible to blister rust than any other species of RibeN, andl is, one of the, dueti agents in its long-distance spread and local establishment, the eradicatti o this plant inl white pine reg.ons is a general control n1~siethat will ]!e of, material aid in checking the spread Of tile disease. D uring the past sao 70,927 of these plants, were eradic ated inl six _North~ealstern and Lake 'States. This work has been completed in Rhode Island and in large, parts ofsera other States. In the Appalachian region black currants are very selreaid in the West they have beon eradlicate I in the wNesterni white pilne and sugar pine regions.

control campaign. The heaviest infestations were centered in Michigan, Wisconsin, Minnesota, North DI)akota, and Montana, but graisshop)liqers occurred in sufficient abundance to require control in the States of South I)akota Iowa, Colorado, Wyoming, Kansas, Arizona, Idaho, California, Nevada, and New Mexico. A considerable portion of this reduction in populations, compared with 1934, may be attributed to the success of the control campaign. The infestation in the northern part of North )Dakota and Minnesnta wns undoubtedly increased by migrations of grasshoppers from Canada. The requirements of the various infested States for control in the spring of 1935 were successfully met with the funds and materials available.

After the completion of the control campaign late in the summer of 1934. a survey of chinch bug abundance was conducted, c operatively with .arious States in the Corn Belt, to determine their probable abundane in the spring of 1935. This survey revealed the presence of the highest overwintering pol)llations of chinch bugs on record in Ohio, Indiana, Illinois, Missouri. and, Iowa, and populations of menacing proportions in the States of Oklahoma, Kansas, and Nebraska, and in southern Minnesota, Wisconsin, and Michigan. A considerable increase in the area covered by the infestation was also observed. Recognizing the emergency nature of this situation, should spring weather conditions be favorable for chinch bug development, Congress appropriated $2,500,000 for the control of these insects. The very cold, wet spring delayed migration until after June 30, the indications bein" tlat, although severe local outbreaks could be expected in some of the States involved, the extremely wet weather over most of the area had reduced the outbreak to a level at which it was not so serious as that occurring in 1934. In Oklahoma. Kansas, and Nebraska the infestation was practically eliminated. Detaled studies on improving barrier methods and materials, and in determining methods of preventing severe infestation by reducing or eliminating certain of the small grains are being made, and more accurate methods of evnalu:ting chnch bug abundance have been developed.

In the summer of 1934, in addition to the usual abundance surveys made in selected areas known to be infested, a survey was conducted to -dineove any, extension of European corn borer invasion around the margins of te known infested area. This survey revealed only minor spread of the ,' bovr ( rin the past 2 years. Damage surveys indicated extensive loss to sweet-corn growers along the eastern seaboard, particularly in MIassachusetts an(l Connecticut. and on Long Island. An increase in infestation was noliced in Neo', Jersey and in two counties on the Eastern Shore of Virginia. However. i1, infestations in the one-zenerat'on area in western New York, Ohio, and Indiv)' has maintained approximately the same degree of severity for the past 1 yoerDuring this period climatic conditions have been definitely unfavorable t, corn borer increase.
Varieties of field corn resistant to corn borer attack have beoon fuirthotested and have maintained their resistance to the borer. In co0oe tie ,vi the Bureau of Plant Industry, further crosses have been made of th(se rsoi:,: varieties, and on effort is bing made to) discover new resistant charaet < new strains resistant to the borer. This work has now been eotend'e1 tstudies of resistqane in sweet corn for utilization in the sw'veet-corn .a:]ni,* areas and market producing centers.
Resistance of alfalfa to the attack of the alfalfa aphid, appIroaching ahs lte immunity, has been definitely proved in a number of trIins selected frm varieties of alfalfa widely grown in Kans, s and Clifo ,nia. The st ,in's have been carried t hrolig a nu1n6er of "O!,*ra i-a! 1(1 suljected to everQ test. Results indicate that resistance is inhlerited. EItoented attempt ts )o i-nkol:tne strains of aphids that are able to survive on the resistant plants have resulted in failure. An effort is being made. in cooperation with thle IUreau of I'lan t Industry, to develop strains of alfalfa having desirable agronoiic characters combined with resistance to aphid attack.

These cultures were made from individuals collected in the field in Virginia, in April before corn was planted, and the insects apparently had carried the infection over winter.

The summer of 1934 was marked by one of the most severe and general outbreaks of the corn earworm ever recorded. From Ohio on the east to Iowa and Nebraska on the west and from Minnesota southward to Arkansas the insect wreaked havoc with the corn crop. In Iowa alone the loss to corn was estimated to have been at least 10 percent of the crop. Other crops, such as tomatoes, were severely injured throughout this region.
For several years limited investigations have been conducted in an effort to obtain practical control of this pest in corn. These studies have been intensified and expanded and a full program has been set up with a view to determining fundamental facts regarding the insect, including the geographic limitation of hibernation. Some 13 observation stations, lo;ated from Kansas and Nebraska eastward to the Atlantic coast and as far north as Connecticut, have been established for this purpose. At four of these stations, located in Virginia, Missouri, Indiana, and Kansas, respectively, intensive observations on all phases of the behavior of the insect are being carried on. Included in this program are investigations of resistant strains of corn, control through insecticides, and the utilization of variation in farinm practice or cultural control.

During the year it was demonstrated that, contrary to common belief, the eggs and young larvae of the flour beetles pass unharmed through the milling process. This indicates that infested grain and infested clear and low-grade flours fed into the product for blending constitute the most important sources of infestation for flour in the mills.
The relative efficiency of the several standard fumigants used to protect stored grain has been determined. The perfection of a method of applying one of these, viz. hydrocyanic acid gas, to milling equipment has resulted in lower costs for fumigants, increased efficiency, reduced labor charges, reduction in loss of running time, and elimination of loss because of stock ordinarily removed from milling machinery and sold as stock feed.


Issuance during the fiscal year of 16,184 certificates for commodities requiring Federal certification to meet the requirements of State quarantines or orders on account of the European corn borer (Pyrauista nubilali.s IIm.) was an increase of 55 percent in the number of certificates required in the same territory during the previous fiscal year. Articles covered by these certificates had an estimated value of $186,.391. This sum is 83 percent greater than last year's estimated valuation of certified commodities. With the exception of November 1934, when the number of certificates issued approximated that of the previous year, the monthly certificate requirements uniformly exceeded those of any previous month since reorganization of the Federal corn borer inspection service in Jamnuary 1933. Stimulated sales of roots and plants of dahlia largely occasioned the demands for this type of iispection an(d certification.
State European corn borer quarantines or orders necessitating maintenance of a Federal inspection service remai (led unchanged (luring the year. IEntry of likely carriers of the corn borer from infested States into Arizona, California, (Colorad(lo, Georgia, Louisiana. Nevada, Oreg(n, Texos. and Utah was still conditioned on Federal inspection and certification.
Few of the State quarantine orders were revised or r ,isud during the year. In a revisionll effective January 15, 1934, the Nebrash; Slate (quarantine was changed to eliminate celery, ot an(1 rye straw. cosmn os, zinniia, and hollyhock from the articles under regulation. Restrictions fornmorly imposed by the Nebraska quarantine on the movement of vegetal)le and floral plants from Indiana, Michigan, and Ohio were also eliminated. A supplement to Colorado European corn borer quarantine no. 4, effective May 1, 1935. permitted entry into Colorado until July 1, 1935, of cornstalks and fodder when sweetened and processedl in hammer mills approved by inspectors of this Bureau. The State of Illinois on May 8, 193t3. modified its corn-hborer quarantine to permit admission into that State of g-reen sweet corn and corn

certificates to uninfested establishments during the fall of 1934 and until April 15 of the spring of 1935. For the purpose of obtaining infestation data in areas of the State from which oat and rye straw is certified, additional counts and inspections were made in the northern and western sections of the State for possible infestation spread and population increases.
Stubble counts for corn borer infestation were made in the less populous sections of Long Island by the inspector stationed in that district. In thoroughly canvassing the island late in the fall, there were examined 5 fields in each section and 125 stubbles in each field. Observations in connection with the survey showed that many of the farmers in 1934 cut their corn stubble at the ground level in accordance with good corn borer control practice. This was particularly apparent where sandy soil had been well cultivated during the growing season. Not much corn is grown on the eastern end of Long Island, so it was with difficulty that the inspector located cornfields there for counts of infested stubble. Nevertheless borers were quite evident in many fields. The survey extended to 26 localities and included counts in 51 fields, with a total acreage of 307 acres. Infestations found in Nassau County ranged from 2.4 to 52 percent, most of the stubble showing approximately 30-percent infestation. The highest infestation was found in a 4-acre field of sweet corn at Jericho. In Suffolk County negative counts were made at West Islip and Lake Grove, with other points showing infestations ranging from 0.8 to 43.2 percent. Infestation in this county is apparently heavier in the northern section than in the southern townships. At Southampton, the easternmost point to which the survey extended, 2 fields examined showed respective infestations of 15.2 and 21.6 percent. Fields of dahlias examined as a part of the corn borer inspection of dahlia roots disclosed further heavy infestations of the borer. One field in particular at Quoque, on the eastern end of the island, showed an especially heavy stalk infestation. As many as 11 bor;'ers were taken from a medium-sized plant.
Degrees of corn borer infestation in heavily infested sections of Connecticut were determined by four scouts employed by the State Agricultural Experiment Station. It was found that the infestation in the State equaled or exceeded that of 1933. Some fields evidenced 100-percent infestation. In the New Haven area inspection of one shipment of beets to comply with the Maine corn borer quarantine disclosed heavy infestation in the tops, resulting in refusal of certification. This condition was reported as rather general in that section of the State. Corn borer destruction of sweet corn wnas somewhat general throulout the State. causing the growers considerable loss. Prices of roasting ears harvested from infested fields were so low that some farmers plowed under their crop rather than harvest it at a loss. Local sweet corn shipped into the Boston market was more heavily infested with the corn borer than for several years past. A prominent Vermont canning factory appealed to its corn growers to practice corn borer control to insure the quality of their crop. Stalk infestation as high as 50 percent was observed by State nursery inspectors scouting on the Eastern Shiore of Virginia. The borer was found generally established in Acconac and Northampton Counties, from the Maryland line south to Cheriton. Completion of a preliminary survey of infested territory in Pennsylvania by entomologists of the State showed that there were fewer borers in the northwestern sections than in 1933. An increased I 'in estation was observed in most of the recently infested counties in the central and east-central sections. Investigations in the oldest and imost hevilyv infested areas, in Erie and Crawford Counties, showed a continued decrease in borer population.


The quarantine on account of the black stem rut of grains (Piccinia praminis) regulates the interstate movement of barberry :1 Mahonia IiPlants, except lerberis th unbergii, the Japanese arherry, and its rut-iminmune varieties. These regulations provide that nurseryinen who grow only rust-resistant species, as determined by inspection, may be granted permits for shipping to the grain-growing States of Colorado, Illinois, Indiana, Iowa, Michigan, Minnesota, Montana, Nebraska, North Dakota, Ohio, South Dakota, Wisconsin, and Wyoming. Such action is in support of the campaign waged for several years by the Department and the above States in destroying those barherries that spread the rust. Applications of 23 growers and 1 dealer were approved during the year, authorizing shipments under these regulations. Thirty ship-

140 additional men were given 2,486 man-hours of employment in connection with the barberry-eradication program by the Virginia Emergency Relief Administration.

Common salt was most generally used for eradication during the year. Less than 1 percent of the barberry bushes were found to survive )rcpier treatment with salt. From 10 to 15 pounds is the recommended application for a bush from 4 to 6 feet high. Bushes are dug only where the salt treatment would endanger nearby trees and shrubbery.
Sodium chlorate alone or mixed with sodium chloride proved ailn effective
killing agent when applied as a spray and drench, particularly ill vinnection with eradication of native barberries (Dcrberbi can ) iii southwestern Virginia. A gallon of the solution (containing 2 pounds of chaeinical) wIs
found sufficient to cover 40 square feet of ground surfce. Other cleimicals used experimentally have not proved as effective, economi1al. readily available, and safe to hale as common salt.
The various informational activities constituted anl important peit of fi the preeradication work during the year and included deimonstratioii.: at local. county, and State fairs, news articles in local papers, illustrated talks I ofori rural and urban school groups, and the distribution of illustrated pariaplllet lesson plans, and circular letters.
During the year school children reported a total of 6S9 properties on whi barberries were growing, resulting in the eradication of more than n.i
bushes. The interests of school children and adults have been eIlcoura;* through a carefully organized educational program in each of the States. a regular part of the field program during the year, brief illustrated tal:
were given before 5,933 schools in 70 counties. Results of this work by State are shown in table 16.

that losses from this pest can be reduced by proper fertilization, crop rotation, and early planting. Where an abundance of land is available the noncultivation of land for one season will also aid materially in reducing wirewormin populations.
The Gulf wirewormn (Heteroderes laurentii Guer.) is becoming of greater importance each year in the Gulf region and on the Coast:al Plain. This wireworm is likely to be more al)undant in land that has been tilled year after year than in untilled land.

The Mexican bean beetle continues to be the most important pest of beans in the United States, and while the winter survival for 19.34-35 was lower in Ohio than it had been for several years, with favorable spring conditions the beetle populations built up to the point where the insect caused considerable damage. Both field and laboratory tests of many types of insecticides have been conducted in Ohio and Virginia. The work with insecticides showed qu'te conclusively that derris powder mixed with water and applied as a spray gave exceptionally good control of the bean beetle, both in Ohio and Virgin'ia. Cryolite also was effective. For sonre unexplained reason, the dosage of magnesium arsenate, that is, 1 pound to 50 gallons of water, which heretofore had been effective in the control of the bean beetle has not yielded the same results during the past few seasons, and it is now necessary to use 2 pounds of magnesium arsenate to 50 gallons of water in order to bring about the same results. This high dosage may result in some injury to the bean foliage.
With the establishment of pea-canning factories in the Northwest, tihe control of the pea weevil has increased in importance. The utilization of a border trap crop and the plowing under of these border plantings prior to the time that the main plantings blossom have given encouraging results. During the latter purt of the year this work was expanded to include studies of the weevil in the Dayton, Wash., area.
The pea aphid again caused heavy losses to the pea growers in Wisconsin, New York, and Ohio. The investigations this season consisted primarily of field-plot tests with several insecticides, and while the results to (late are only of a preliminary nature and cannot be used as a basis for reconiumendations on pea aphid control, the indications are that a derris powder spray may be useful against the pea aphid.
In the beet-growing area of southern Idaho the early-season indications were that heavy leaf hopper populations could be expected. The early-season prospects were borne out by large numbers of leaf hoppers appearing in the beet fields late in the spring. In California, studies on the migration of the leaf hopper and its desert host plants have been continued. Observations have also been continued on the effect of spraying desert hosts and the elimination of Russian-this le on leaf hopper populations. The actual operation of these two latter activities was conducted by the sugar companies and the State workers.
An added feature of the leaf hopper work N\as the outlining of thle critical breeding areas of the leaf hopper in southern Idaho. This work had foi its objective the possibility of controlling weeds in the abandoned land and desert areas through proper land handling as a means of reducing leaf hopler I)populations. Evidence accumulated indicates that native grasses which are not hosts of the leaf hopper will replace the introduced weed hosts in the large breeding areas if given an opportunity. Similar studies have 1)bee ca rried on in Utah and Colorado; however, the areas involved here are much larger than in sou'hern Idaho, and consequently the information regIarding the critical breeding are:s of the leaf hopper in these two States has not been as complete as for sout hern Idaho.
Derris powder has shown excellent promise as a control for the tobacco h11, beetle, especially in the seed beds. Similar control has been secured in tihe field, but the cost of such treatments has not been determined. Iarium fluosilicate, heretofore reported as useful in the control of flea beetles in the shadegrown tobacco areas of Quincy, Fla., has not proved satisfactory during the past season, as it may cause considerable injury to the tol) (: i.plant.

In the investigation on mushroom pests special emphasis has been placed on possible use of napthalene and paradichlorobenzene. Chemists of the Division of Insecticide Investigations have been associated with these studies.


The narcissus-bulb quarantine was revoked, effective April 1, 1935. This action was taken because attempts at general eradication of the eelworm and the greater bulb fly had not been successful, the pests occurring year after year in most areas where such attempts had been made. Furthermore, both these pests have become established in commercial bulb plantings in many States in addition to those in which they were known to occur in 1926, when the quarantine was established.
The removal of the Federal quarantine left the interested States free to act in placing such restrictions as they deemed advisable. The State of Oregon thereupon issued a quarantine on the entry of narcissus bulbs, with inspection and fumigation requirements similar to those formerly in effect under the Federal quarantine. State officers of Florida, Virginia, Pennsylvania, Michigan, and Texas announced that inspections of narcissus would be made the same as when the Federal requirements were in effect, and Maryland officers announced their intention of continuing inspection of these bulbs as part of the general nursery-inspection program.
For the season of 1934 the State nursery inspectors in 27 States reported to the Bureau the inspection of 235,486,085 narcissus bulbs. Detailed information on the number of plantings and bulbs and the extent of treatment in the individual States is given in Circular B. E. P. Q.-373, issued on April 23, 1935.
From July 1, 1934, to April 1, 1935, 154 violations of the quarantine were intercepted at transit-inspection points.

The issuance of information on the distribution and abundance of insects attackIng cotton, together with timely advice on methods for their control, was resumed during the year. Reports about cotton insects were included in the Insect Pest Survey Bulletin and in press releases and radio broadcasts along the same general lines followed with insect pests of other crops.

The initial bolhveevil infestation in the crop season of 1934 at Tallulah, La., was comparatively high, but the hot, dry weather from June 18 to the end of August held the weevils in check. Experimental plots dusted with calcium arsenate following standard recommendations gave an average increase of only 236 pounds of seed cotton per acre, or 19.5 percent, as compared to 419 pounds, or 45.4 percent, during the previous year.
A large series of field and cage tests were conducted to determine the efficacy of a number of insecticides, mixtures of insecticides, and insecticides diluted with carriers. The tests at Tallulah showed the value of several other nmaterials for bollweevil control, but none was found to be superior to calcium arsenate dust. Mixtures of calcium arsenate and hydrated lime, mixtures of paris green and lime, and a mixture of calcium arsenate and copper arsenite gave good results. These preliminary results suggest that these materials may be useful for regions where it may be desirable to reduce the amount of arsenic used or when other insects, such as the cotton flea hopper and cotton leaf worm, must be controlled along with the bollweevil. Tests with thiodiphenylamine (phenothiazine) and sulphur, and with derris root in inert carriers, indicate that these may have a place among effective nonarsenical poisons. Tests conducted to compare the results from dusting with calcium arsenate early in the morning. at midday, and late in the evening were favorable to the early morning applications; and tests to compare the results of dusting at 4-, G-, and 8-day intervals were favorable to the 4-day program.
For the third year in succession, in tests at Florence, S. C., a mixture of equal parts of hydrated lime and calcium arsenate was as satisfactory for the control of the bollweevil as calcium arsenate alone when each was used at the rate of about 7 pounds per acre per application. Other mixtures of lime with calcium arsenate and with parts green gave good results.

The outstanding developments of the year in the pink bollworm situation were the finding of infestation in several additional counties in northern Florida and western Texas, no recurrence of the insect in the original infested areas of Florida and Georgia, and c()ontiinued progress in the eliadication of wild cotton in southern Florida and in the special control I)rogram in the Big Bend of Texas.
The new findings involved 7 counties in Florida and 3 in western Texas. The fact that only 20 specinmens were found in these 10 counties indicates that the infestations are extremely light. As mentioned( in a previous report, the discovery of such light infestations is due to improved methods o()f inspection, particularly to the use of the gin-trash machine.

On September 3, 1934, one larva of the pink b'ollworm was found in gin trash at Bascom in Jackson County. Jackson is the largest cotton-producing county in Florida. Additional gin-trash machines were sent to the area, and practically all trash in the county was inspected during the remainder of the season. As a result, seven additional specimens were taken at Bascom, and on September 26 a specimen was found in trash at Cottondale, also in Jackson County. Nearly 2.000 bushels of trash was inspected in this county; consequently, the finding of only nine specimens indicates that the infestation was very light. The other findings in Florida were in Suwaniiee, Levy, and Hamilton Counties, near the regulated area, and involved 3 additional counties, Dixie, Lafayette, and Taylor, which had no ginning facilities. Only seven speimens were found, indicating that the infestation is also very light in these counties.
The Federal quarantine was immediately extended to take in the infested areas but, as the season was well advanced, it was impossihl( to obtain and install the necessary equipment for carrying out all of the regulations. The measures taken to prevent the spread oil the insect consisted in sending the seed to designated mills, the compression of lint, the disposal of gin trash, and the clean-up (f gins after the close of the season's operations. At the close of the fiscal year the winners were making plans to install sterilizing equipment so as to carry out the regulations in full during the coming season.

The eradication of wild cotton in southern Florida was begun in 1932 to eliminate a severe pink bollworm infestation and has been continued each successive year. Because of climatic conditions, this work can be carried on only during the fall, winter, and early spring.
Eradication activities were resumed about the first of November, and, owing to a very dry season, especially good progress was made. All of the areas cleaned during previous seasons were again recleaned. During this recleaniag intensive scouting was carried on to locate any cotton that had been overlooked, and a number of scattered plants and small colonies were found( and removed. At Cape Sable, where most of the wild cotton is now located, a considerable area was cleaned for the first time, and in addition all of the area previously cleaned was covered. Many of the islands and keys in IFlorida Bay were also cleaned. ID)uring the season a first clean-uIp was lad covering 908/ acres, from which 76,920 mature and 58,404 seedling plants were removed. From the area recleaned 6,413 mature, 1,00;(.G21 seedling, and 1 77,477 sprout plants were removed. This mighPt at first appear to he an unusually large number of mature plants to have been found on areas r viously cleaned. As the inspectors had had 2 years' experience with wild cutn, they h:1 naturally become more famnilitar with the v i ius coalitions ui er which it grows, andl during the past year they were able to locate many plants that had been overlooked, as shown by the large number removed. Most of these curred in the Cape Sable area. Because of the importance of maintaining as great a distance as possible between the (ciultivated and the wild cotton, the seven most northerly counties along the west coast where wild cotton oceurs were gone over after the regular clean-up work was discontinued. This was done to remove the seedlings that had come up and thus prevent their fruiting before work can be resumed next fall. It is very encouraging to note that during

Trap plots were used again in the spring of 1935. The cotton was planted in the field, instead of being grown in hotbeds, and later transplanted, as was the case during the two previous seasons. The plots ranged in size from on( fourth to one-half acre. Owing to unfavorable weather, the cotton did not begin growing as fast as was expected, but weather conditions also delayed the field cotton, and the trap cotton began blooming at least a month in advance of the field cotton. Bloom collections were begun on May 20, and within a few days infestation was found in several of the plots. At the end of the fiscal year infestation had been found in all 13 plots, anrd a much larger number of worms is being found this year than last. This may te owing to a deren('e in the emergence of moths each year. On the other hand, it may be because the field clean-up was a little later this year. on account of tl top, crop mentioned above. If so, it indicates very clearly that the earlier the fields can be cleaned each fall the fewer moths there will be the following spring, as worms will have less time to enter the soil for hibernation. The delayed planting date of April 15 was satisfactorily observed. Field cotton in Brewster County has just begun blooming, and a few worms have lh-en found, but the cotton in Presidio County is considerably later, and no blooms have yet been produced.

The new infestation in Texas involved Andrews and Ector Counties and all but a small part of Midland County. The last is not a new infestation, as this area was previously under regulation, having been release February 28, 1933. The last findings had consisted of 2 sl)eclinens it the 190"1 crop. On October 18, 1934. a specimen of the pink bollworm was found in trash at Midland. This was followed by additional findings on October 23 and 24. Owing to the lack of ginning facilities, cotton produced in Andrews and Ector Counties is ginned at Midland, hence they were involved in the infestation. On October 24, 1 )ecimen was found in gin trash at Stanton, in Martin County. An examination of the gin records showed that most of the cotton from which the trash came had been produced in Midland County, with only a few fields from Martin County represented. Intensive inspections were miade in these Martin County fields and the gin trash from the remaining cotton was caught separately and inspected without any indication of infestation being found. It seems almost certain, therefore, that the above specimen or-inated in Midland County, and this information did not seem to warrant including Martlin County in the regulated area. Inspections were continued during the remainder of the ginning season without finding any additional specimens. It will thus be seen that, as was the case in other new areas, the infestation in this area is very light.
The three counties mentioned above were again placed nn(ler regulation, and the movement of products therefrom was handled accordingly. Inasmuch as the ginners had had previous experience with te regulations., they cooperatel whole-heartedly.

Heretofore gin-trash inspection has been nmade in each comity un(ler re aulation to determine whether or not infestation was present a1d if So to wia degree. IT the fall of 1933 green bolls had been collected from a numl)er of lightly infested counties and were later inspected as a check on tile laboratory method. It was demonstrated that a rather light infestation could be discoveredd by this method. Therefore, as an economy measure, a plzIn was worked( out whereby a number of gin-trash crews could be eliminated anl at tie same time a check on the infestation condition could still be taken, aithlouh somewhat delayed. This plan is to collect green bolls in the fall in counties where infestation has existed for some lime. The bolls ore preserved and inspected later in the season, as regulatory activities decrease. In um se no inlestaiP is found in the bolls, gin-trash inspection is to 1)e Substituted the following season.

Intensive gin-trash inspections were carried on in the older regulated areas of northern Florida and Georgia. In Madison County, Fla., 1 Specimen of the pink bollworm was found, but in the other counties of Florida and in the three counties in Georgia the results were all negative. Intensive inspections

All results negative, except that 105 pink bollworms were found in the Juarez Valley of Mexico.
During the fiscal year 1935 two changes were made in the pink bollworm quarantine regulations, both of which were for the purpose of inluli(tg the newly infested sections.
Amendment no. 1, effective September 19, 1934, was made for the purpose of adding Jackson and Suwannee Counties, Fla., to the regulated area.
Amendment no. 2, effective October 31, 1934, was made for the purpose of dtding Dixle, Hamilton, Lafayette, Levy, and Taylor Counties, Fla., and Andrews and Ector Counties, and part of Midland County, Tex., to the
regular ed area.
The above areas were designated as lightly infested. At present the regulated "rea(s include 3 counties in southern Arizona, 14 in north-central Florida, parts of 3 In southern Georgia, 9 in southern New Mexico, and 17 entire coulties and parts of 4 additional ones in western Texas. Of this area five counties and part of another in Texas are designated as heavily infested and all of the remaining area as lightly infested.
No changes were made this past season in the measures enforced to control aid prevent the spIread of the pink bollworm from infested areas. These
consisted of (1) disposal of gin trash, (2) sterilization of seed, (3) supervision of oil mills, (4) fuigiation, compression, steaming, and roller treating of Iit, (51 road stations, and (6) cooperation with Mexico.
Most gins are equipped with cleaning machinery through which the cotton passes before entering the gin stands. A considerable amount of trash is taken from the cotton by this machinery and many pink bollworns are discharged with the trash, the number depending, of course, on the degree of infestation. The regulations require the daily disposal of this trash by burning, sterilization, or grinding. Several years ago the Texas and New Mexico regulations were amended to require the daily disposal of trash to December 1 of each year, the average killing frost date being prior to this. The ginners have

in the southern end, but the bulk of the crop began about 18 miles al)orve Tucson, extending northward about 12 miles. About 2,000 acres of Pirna or long-staple cotton and 5,000 acres of short-staple cotton were grown, and a gin for long-staple and a gin for short-staple cottons were operated. Practically all trash produced was inspected with a gin-trash machine, with negative results. Toward the close of the ginning season field inspections were made of the top crop of bolls, and a light infestation of Thurberia, weevil was found about 3 miles north of Tubac, in Santa Cruz County, and another at Sahuarita, 18 miles south of Tucson, in Pila County. A supply of hollies was collected, and at the end of the year examination of this material had not quite been completed. A few specimens have been foulnd in material from three additional fields, all located near Tucson. None of the material from the Rillito-Marana district, where the bu!k of the crop is grown, has been infested. Only 30 specimens have been found, which, together with the negative gin-trash inspections, indicates that there is a very light infestation in the top crop of bolls.
The measures used in controlling and )reventing the spread of the Thurberia weevil are the same as for the pink bolhworm. These consist of disposal of gin trash, sterilization of seed, compression, fumigation, and roller treatment of lint, and the clean-up of gins, oil mills, etc., at the end of the season. The results of each of these activities are included in the figures given for the pink bollworm.

Pollination studies on the Pacific coast show that bees shift their activities to fruit varieties in accordance with the sugar concentration of the nectar. Fruit-tree varieties within the same species were found to show wide variation in nectar concentration, resulting in wide variability in the pollenizing effectiveness of bees.
Cooperative studies with the University of California on the cost of honey production indicate that the average cost is 6.9 cents per pound, while the average price received by producers during the year was 4.5 cents per pound. Of 225 California apiaries studied in 1933, S percent made a profit, 8 percent broke even, and 84 percent operated at a loss. Similar conditions prevailed in 1934.
Uncontaminated beeswax is known to be white, but white wax required for the manufacture of candles, cold creams, etc., has been difficult to prepare from the crude brown and yellow western beeswaxes. Studies in cooperation with the University of California have shown that brown stains we-e caused by iron rendering utensils. Wax rendered in glass, aluminum, and stainless steel was white or yellow. The source of yellow pigment was found to be pollen, although some pollens do not impart color to beeswax.
Loco weed (Astragalus trichopodus) was found to cause a widle-spread death of adult bees in southern California. It was likewise found that Matilija poppy (Ramneya coulteri) also affects adult bees. Four other plants, three of which occur in California, are now definitely known to be poisonous to bees.
The difficulty of combating American foulbrood, a contagious disease of bees is further emphasized by the fact that the disease has recurred in the experimental apiary at Somerset, Md., in combs that had been treated with formaldehyde and in which healthy brood had been reared for a period of 5 years. Studies conducted in cooperation with the University of Wyoining in an apiary of 1,700 colonies indicated that honey produced above (lut'en excluders in diseased colonies in practically all cases contains enu~lwJi stores of American foulbrood to constitute an infectious (lose. This fact is contrary to the general belief. On the other hand, out of 58 samples of honey, representing a crop of 220,000 pounds from a, commercial -ipiary in Wyomiiwn havig a more or less constant infection of American foulbrood, all showed a spore content less than the minimum infectious (lose.
Work is under way to test the resistance of Caucasian, ('arnia ln, and common black bees to European foull)rood, another contagious 1isse o be(s, and although it is generally concede(d t iat this disease can he readily conitrolled, an unusually virulent type of this disease has heeii found in New England. The in(lcaltions so far are that this particular strain is not a menable to the usual methods of treatment.

habits of this fly along the coast of Florida disclosed that prolific breeding takes place in decomposing piles of Sargassumn sp., a brown marine alga. Destruction of such breeding places would decrease the abundance of the fly.


Experiments carried out cooperatively with the Bureau of Animal Industry and the Florida Livestock Sani ation Commission on the Australian cattle tick (Margaropus annulatus austrulis Fuller) confirm the field observations that deer serve as an effective host of this tick. Apparently, however, there is greater individual and seasonal variation as to the number of ticks reared than in the case of the more normal bovine host.


An outbreak of black flies (Siniuliumn sp.) during the spring of 1935 in Arkansas and Louisiana, especially in the 3.ississippi Delta area, caused considerable injuPy and some deathss in livestock. An interesting discovery, and one which may have a definite bearing on finding some method of controlling these injurious insects which have heretofore been more or less immune to control procedure, was made during the winter of 1934. It was found that under laboratory conditions eggs undergo a period of aestivation for as long as 8 months. Under field conditions the eggs are washed into river cut-offs and bayous, where the stagnant water is unfavorable for development. The advent of subsequent floods and the consequent agitation of the water where the eggs have remained dormant produce ideal conditions for the emergence of enormous numbers of the adult gnats.

Observations on the biology and abundance of eye gtnats in the Winter Garden section of southwestern Texas were carried on throughout the year. In June of the current year a representative of the Bureau was sent to assist in the reorganization of the gnat abatement district of Coachella, Calif., where the residents were anxious to continue the control measures recommended by the Bureau.
Much assistance has been rendered by the Bureau to various loc,'l, State, and Federal agencies in making mosquito surveys, and waging cmnrol campaigns in the States of South Carolina, Georgia, Florida, Alabama, Oregon, and Washington.
In the Southeast, mosquito surveys, with recommendations as to suitae'o control methods, were made at Parris Island. S. C., in cooperation with the United States Marine and the Naval Medical (_'orpe: at Savannah, (;a.. anl Yirktown, Va., in cooperation with the National Park Service; an( at Island and adjacent territory on the North Carolina Uanks. Studies of th, salt marshes and salt-marsh mosquitoes of Florida have been carried out during the year, and assistance has been given to county organizations, the Ste board of health, and the Emergency Relief Administration in mosquito-onvl problems.

Investigations have been carried on, in cooperation with the Pathlo&i a] Division of the Bureau of Animal Indlustry, on the transmission iof the fatal malady of horses known as equine encepihalonyit is by mosquitos. It has been shown in numerous tests that the yellow fever mosquito, Aedes aegypti, is an efficient carrier of the western strain of the disease, but a very poor carrier of the eastern strain. The only instance in which the eastern strain was transmitted from an infected to a healthy guinea pig was in the

During the year special effort has been made to eliminate living host material from the shipments of natural enemies forwarded to the United States. This was largely accomplished in dealing with the parasites of the oriental fruit moth, the Japanese and Asiatic beetles, the pink hollworm, and the hessian fly. In these cases the results were highly satisfactory, and it is planned to extend this method to other activities.
The principal hosts of the parasites imported and the countries inll which the material was obtained were:

Hessian fly ------------------------------------ France.

A total of approximately 25,000 cocoons and 5,000 adults were forwarded during the year. Twelve species of parasites were secured from this material for liberation; the most abundant of these were Dioctes nmolestae Uch., Phaeogenes nigridens Wesm., and Macrocentrus thoracicus (Nees). The success attending shipments of adults is illustrated in the case of a consignment of 4,096 Phaeogenes nigridens females forwarded in cool storage via Panama. This shipment reached the laboratory at Moorestown, N. J., 5 weeks later with less than 1 percent mortality.


The importation of parasites of these beetles from Japan and Chosen has continued on a small scale. Shipments were made of Tiphia popilliarora Roh., a larval parasite of the Japanese beetle, Tiphia sp. no. 29, parasitic upon the Asiatic garden beetle, and Tiphia sp. no. 6-b, parasitic upon the latter host and the imported serica. All of these were shipped in the adult stage.


What is expected to be the last bulk shipment of corn borer larvae from Europe was collected in northern Italy in November and December 1984 and forwarded to the United States in January 1935. This comprised a total of 1,113,000 field-collected larvae and was estimated to contain 17,000 Inarcolata punctoria Ronman, 167,000 Lydella grisesceas II. D., and 4,730 Eulhnmneria alkae E. and S. All of these are larval parasites already established in the United States and are to be used in extending the area of colonization.


Investigations of the parasites of this pest of cotton were started in Egypt in October 1934. Colonies of adult parasites of several species for rearing purposes were secured through the courtesy of the Egyptian Ministry of Agriculture. Shipments were made of Microbracon kirkpatricki Walk.. a promising parasite originating in east Africa, Exerites roborator (Fab.), and Llaxmus sp. All of these arrived in excellent condition and are now heine' reared in quantity at the laboratory of the Division of Cotton Insect Investientions at Presido. Tex.

The testing of various household insecticides against house flies by the method of Peet and Grady and by a turntable method, which was devised in the Division of Control Investigations, was carried on in cooperation with various insecticide manufacturers. The object of these studies is to improve the methods of testing so that satisfactory specifications for fly sprays can be written. One of the requirements is the adoption of a standard insecticide with which unknown samples may be compared. Phenothioxin was found to have some promise as a standard.

In cooperation with the Division of Drug and Related Plants of the Bureau of Plant Industry, the insecticidal action of extracts of some 3C0 samples of roots of Cracca, chiefly C. virginiana, collected in 18 different States, was tested against house flies. The most effective roots were found in eastern Texas, southwestern Georgia, and Florida. The plants found north of Georgia possessed very little toxicity. The sample most toxic to house flies was collected in Harrison County, Tex., and contained 1.8 percent of rotenone. The demonstration of correlation between the Durham qualitative color test for rotenone and the effectiveness of the extracts of Cracca has facilitated the search for plants of high toxicity and the selection of plants for cultural experiments.

In cooperation with the Food and Drug Admninistrtion, tests, of the insecticidal action of samples of extracts of pyrethrum were made to find which of the three methods of chemical analysis for pyrethrins was best correlated with the insecticidal properties. Tests were also made on the insecticidal effect of mixtures of alcoholic solutions of pyrethrins and rotenone.

Some 200 synthetic organic compounds, made or obtained by the Division of Insecticide Investigations, were tested during the fiscal year against mosquito larvae. In addition to phenothiazine, which was more toxic than rotenone to culicine mosquito larvae, 14 other compounds were found that compared favorably with rotenone in toxicity. Organic compounds of iodine were found to be more toxic than organic fluorine compounds.

A method applicable to testing the effect of light on the toxicity of various types of insecticides by imbedding them in a thin film of gelatine was worked out during the past year. When cabbage worms were fed gelatine film containing derris, in cabbage-leaf sandwiches, they were killed. Pyrethrum powder fed in the same way did not kill them. On the other hand, the cabbage worms

Derris and cube continue to hold front rank as organic insecticidal materials, and the study of them wvas continued. Considerable progress was made in the attempt to, correlate the toxicity of particular samples with various chemical determinations- which it is lhoped, will lead to the possibility of evaluating such materials in the chemical laboratoi'y without recourse to laborious biological testing. A critical study of the methods of determining rotenone was also carried out. which unearthed c ertain errors in the previously used procedure and led to the development of a more, satisfactory method. Craeca viryiniana, or devil's shoestring, continued to be the only American plant in which rotenone has been found. During the year an exhaus-tive study was made of several hundred samples. Of these. samples. 3.30 were collected by the Bureau of Plant Indiustry in its survey of the uccurr( nce of this plant over the United States, and the results show that the best samples collC from Georgia, Florida, and Texas. Two samples were found that contained 1.8 percent of rotenone; many contained only traces or none at all.
Considerable attention was devoted to nicotine, including a search f'or in-soluble nicotine compounds. One promising new inaterial oif this class-- wai develop-ed. This product, called nicotine-peat, is the result of the comlbination of icotine with powdered pe,;at-. Some peats when usdin their natural state hold as mch as 9.9 percent of nicotine in relatively i'olub1le form,. and after siinp1l( acid treatment some others, can holdl as much as 13.7 percent. A sc ond lnmateria a solid soluble by-product of the other, known~ as nicotine humate. was developedt at the same time, and may find a place as a substiltte for the more volatile niicotine su11phate. It contains about 83 percent of iticotine.

The study of the relative toxicity of insecticidal materials to goldliah. which has as its object the discovery of possible relationships between twx'icity and chemical constitution upon which future synthetic work cain he based(, ws continued throughout the year. The principal experimental study invoived the determination of the relationship between the optically active and optically inactive isomers of dihydrodeguelin. It was found that the opl ically active compound is approximately twice as toxic a s the inactive compound. This fact has an important bearing on the question of the toxicity of derris.-, cube, and other rotenone-bearing roots, for it is now believed that the deguelin they contain is optically active, and hence it may be appreciably more toxic than the inactive variety on which all toxicological resuits have been based so far.
A rather extensive investigation of calcium arsenate was undertaken. The dependence of the insecticidal and phytocidal properties of calcium arsenate on its mode of preparation and finished chemical constitution is not well understood. The work during the year confirmed the existence of a previously suggested definite basic arsenate which can be called tetracalcium arsenate. A phase-rule study of the whole system (lime, arsenic acid, and water) was also started in the hope that the higher temperature adopted, 62' C. (143.50 F.), will result in attainment of equilibrium, a goal that was not reached in a similar study conducted several years ago at 350 C. (95 F.).
A few examples of the miscellaneous analytical and investigational work done to aid in various activities of the Bureau indicate the scope or volume of these activities. One hundred and ten samples of miscellaneous insecticidal materials, such as calcium arsenate. spray oils, and fluorine compounds, were analyzed to check on their suitability for experimental use: 70 samples of derris, cube, and other rotenone-containing powders were examined: numerous chemical reagents were tested for arsenic for the Bureau of Chemistry and Soils, etc. Analyses were made of 380 samples of pine wood to which insecticidal materials had been applied. Of these samples, 19' were from trees injected with sodium arsenite, 30 from trees receiving copper sul hate, 96 from trees to which mercuric chloride had been applied, and 49 from trees that received sodium fluoride. These determinations required the development of special methods of analysis, since the resins in the wood interfered with the application of the methods ordinarily used for insecticidal elements in organic materials.
A search was made through the 737.500 United States patents issued during the 17-year period from 1917 to 1933,. inclusive, and 47 mimeographed lists containing the numbers and brief abstracts of those relating to insect-destroying devices, insecticide sprayers and dusters, fruit washers, and washing procedures, etc., were issued.

Transit inspection was inaugurated at a few strategic railway terminals in 1920 for the specific purpose of enforcing the white pine blister rust quarantine in effect at that time. The value of checking mail, express. and freight shipments of restricted plants in interstate movement, and turning back those moving to uninfected regions. was immediately recognized, and the work has been expanded from year to year to cover other railway centers and to include enforcement of all Federal domestic plant quarantines. The effectiveness of such inspection is shown by the gradual reduction in the percentage of violations found. There were 11.9 violations per 1.000 shipments inspected in 1920 in the enforcement of 1 quarantine, and only 0.6 violation per 1,000 shipments inspected in 1934 in the enforcement of 11 quarantines
Of special interest in the work of the fiscal year 19835 was the findin of 50 live Japanese beetles at Chicago on July 11 and 12 in a refrigerator car of beans arriving from New Jersey. The ear had been partially unliaded. nwl careful inspection was immediately made of all hampers available at eomnmission-merchant houses. Intensive inspection of produce arriving from ithe infested areas was continued lthrouzhout the summnier by ins)ectors of the .Japanese b-etle and transit inspection projects. find S liv, bo,,tles anl 157 dead ones were taken from 97 of the .14 cars inspected during the ,oson. han cars contained the largest number of beetles.

Under the provisions of Quarantine No. 7. on account of tihe Dutch elm disease, 50 elm logs from Europe were imported subject to hot-water treatment as follows: Through the port of Baltimore, 20 logs; through New York. 8 logs; and through Norfolk, 22 logs. Hot-water treatment was applied at the following places: Baltimore, 20 logs; Indianapolis, 8 logs; New Albany, nd., 14 logs; and New York, 8 logs.
Quarantine No. 70, effective October 21, 1933. providing for the entry of elm logs from Europe if free from bark, subject to hot-water treatment as a condition of entry, was amended. effective .Jnnuary 1, 1935\, to prohibit the importation of elm logs from Europe. This action was taken for the reason that logs were arriving with the bark incompletely removed. In some cases the adhering remnants of bark were found infested with living adults and larvae of scolytid beetles, which are known to have a part in the spreading of the fungus causing the Dutch elm disease.

1 Cottonseed hulls are permitted entry only from the Imperial Valley, Baja California, Mexico.
2 Includes 7,400,000 pounds of fertilizer composed principally of cottonseed meal.

In addition, the Bureau supervised the entry of 18,8-3 samples of cotton, cotton linters, cotton waste, and bagging imported by freight, express, and
parcel post, and as passenger baggage.
This year's importations of cotton waste are the largest since 1923. Of
outstanding interest, however, are the importations of cottonseed cake. meal, and oil, which represent for each commodity the largest yearly importations since cottonseed products were placed under restriction in July 1917.

Table 37 indicates by ports the number and disposition of foreign mail packages inspected during the fiscal yet-r.
Table 37 includes shamrocks, which are permitted entry through tlhe Inails provided they are free from soil.
