INTRODUCTORY STATEMENT

In this the first number of the third volume of the Insect Pest Survey bulletin, ,e are inauurating a new feature. Through the generous cooperation of the entomological forces of the Dominion of Canada we are able to include a monthly review of the outstanding entomological features of the ireat territory lying north of the United States which has so many enrtoological problems in comcn with the northern States of this Union.

An Insect Pest Survey of the Dorinion of Canada, w-orkin7 along similar lines and with the same general purpose as this Survey, has recently been institute: i ":i is xnsr the supervision of Mr- R. C. Treherne, Chief of the Piviision of Field Crop and Garden Insects of the Canadian Dep_ rtrent of r-iculture.

The appearance of he Ar-ual Su7-ary of insect condition,
throughout the United S ,,t' f: the season of 1922 will be delayed somewhat, as the Survey is at-eptin to review a ::_uch more comprehensive broup of inects than -as reviewed in the first Annual Summary. In addition to the 1-arger scope of the summary the mass of data being received from the States is constantly increasing.

During the past winter the distribution records of the Survey
have been very materially au- ent. by the extreme generosity of our collaborators in three State-, who have very kinily loaned us their entire file of correspondence record cards, in one case extending back to 1888. These cards indicate the name of the insect, the date and the place, and in some cases the crop attacked as referred to in each letter received at the Station. These records very clearly iri4cate the parts of the State where certain insect pests are most frequently attracting the attention of the agricultural population, and when similar data are lrou ht to-cother over a reasonably large area Sthe region of optimr conditions for the successful life of a givenppest can soon be ascertained.

OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES

FOR THE PERIOD FROM NOVFM!FR 1, 1922, to APRIL 1, 1923


The temperature throughout the United States during the period covered by this report was generally above normal except during the first, second, and third weeks in February when below-normal departures were experienced over the greater part of the country. During the second and third weeks in Dececber there were also minus departures throughout the greater part of the T'ississippi Valley, New England, and the I'iddle Atlantic States. The New England States, as a whole, experienced a somewhat below-normal winter, minus departures bein, almost continuous from the beginning of January to the end cf February. The Pacific Coast States had cold weather during Ncverber and the first half of December and again the temperatures were below norr-al during the last week in January and the first two weeks in February. Abnormally cold weather prevailed in the Great Basin during November and February. Tercpratures were above normal in the Southrest from early in Novrmbr until the end of January. Th' Rocky Iountain region had minus departures during November, tho second and third weeks in December, and the first three weeks in February. Temperatures in the' North-Central States were above normal w1ith the exception of the second and third weeks in December and the ronth of February, similar conditions rrevailing ovur the est-Contral and East-Central States. The temperature in the Lower hississippi Valley was gen rally above normal as was also the case in the Middle Atlantic States except in the month of February when minus departures were recorded. The South Atlantic States had very similar departures to those of the Middle Atlantic.

The drought that prevailed between the .ississippi Valley and the Rocky Mountains during the latter part of the summer was relieved early in Nov mber; droughty conditions, however, continued in most of the Middle Atlantic and South Atlantic States during this month. In December the drought was relieved in the
Lower MIiddle Atlantic and South Atlantic States, while this month showed a deficiency of rainfall in the Hississippi Valley. The January rainfall was below normal in the South Atlantic and Gulf States and above normal in the Middle Atlantic and New England, while in most of the Upper Tississippi Valley, except Wisconsin and Minnesota, it was belo' normal. The Rocky Mountain States also showed a deficiency of rainfall in January. In February from the Great Plains to New England the rainfall was below normal, while in the Rocky ountain focthills and the Gulf region it was above normal. The South Atlantic States during this month, as well as the Great Basin, the Pacific Coast, and the Rocky Mountain States, were all experiencing dry w:at'er.

The mild weather has favored the successful overwintering of the chinch bug and it is now found to be present in winter quarters in threatening numbers over the greater part of southern and central Illinois, southern Nebraska, and eastern Kansas.
The green bug appeared in numbers sufficient to produce an epidemic early in the season in northern Texas, Oklahoma, and southern Kansas. Though still widespread, it is not at present considered to be a serious menace. During the spring it was also reported from Louisiana and New 7exico.




4 --












The annual examination of hibernating quarters of the cotton boll weevil made by the Bureau of Entomology's Delta Laboratory indicates that
this insect has not passed the winter well in northern Louisiana and we may expect a much decreased spring emergence in the general region than was the c~'se last year. In Alabamal however, reports have been received that a very high percentage of the weevils has passed the winter successfully.

The clover-leaf weevils are still, apparently, on the increase in Illinois and heavy damage is anticipated this season.

The spring cankerworm was observed in flight on M arch 9 in M'issouri and on March 13 in West Virginia.

The fall cankerworm was emerging and ovipositing in serious numbers in
Morris County, N. J., the last week in March.

The San Jose scale is attracting increasing attention in Rhode Island, Ohio, Georgia, Indiana, Illinois, Idaho, Texas, arnd New Fexico. The limesulphur spray, possibly owing to faulty application, is not proving as satisfactory as formerly and some States are recorrrending lubricating-oil sprays.

The first adult of the plum curculie was observed on March 5 in Georgia,
indicating that the beetles will probably appear in numbers from hibernation by the tire the peach trees are in full bloom.

The large numbers of hibernacula. of the pecan case-bearer that are
present in the semiarid pecan-growing sections of Texas seriously threaten the
otherwise promising crop for 1923.

The orange basketworm is reported as causing serious darrage to the fruit and young growth of several large plantataions in Florida, the dara -e in sore
cases running as high as 20 per cent of the fruit.

The European red mite is now quite prevalent in the fruit sections of
New York, Connecticut, and Ohio and scattering infestations have been found in 1:aryland .

Indications of a serious outbreak of the pea aphid in the San Francisco Bay region of California have been reported.

The onion thrips is causing serious trouble in the important canteloupe growing section of the Imperial Valley in California. The thrips are now attacking the early vines under their frost protectors.

The common field cricket is reported as seriously infesting 2C0 acres of lettuce in San Benito County, in some places necessitating planting the crop three times.

Reports have been received froir California that the cattle tick and cattle scabies are no longer present in that State.






OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA

FOR THE PERIOD NOVEMBER 1, 1922, to APRIL 1, 1923


The winter in Canada has been more severe in the eastern sections than in
the 17est. The depth of snow in the I-aritime Provinces has been exceptional. In V7estern Ontario, except for a few mild days in the latter part of February, the winter has been cold and steady, with a much greater fall of snow than is usual. The same applies, to some extent, to Yanitoba; but in Alberta the winter season has been mild, with a light snowfall. In British Columbia the winter season has been open and the spring is earlier than usual.

The European corn borer has inciaased its area of infestation in Ontario
during 1922 by 45 townships, and now involves an area of 12,616 square miles, with
162 townships under quarantine, There was, however, but slight increase in the area of heaviest infestation and a light general decrease in intensity in the area where cooperative control measures have been carried on. Overwvintering larvae in
the crop refuse under observation, to date (February 25), have suffered slight mortality, protection being afforded by the sncw blanket over the whole infested area.

The roadside grasshopper (Camnula pellucida Scudd.) occurred in extreme outbreak form on the cattle ranges of thb Nicola Valley in British Columbia during 1922. The general situation and the winter conditions would indicate a continuance of the outbreak during 1923. In the Prairie Provinces the situation is much relieved, though an ascendency in the numbers of the lesser migratory graesopper has been observed in many sections.

The pale western cutworm remains the most important grain-insect Trobler in southern Alberta. It would appear that the same acreage is infested year after year with the centres of infestation constantly shifting. From the precipitation records of 1922, the greatest degree of prevalence will probably occur in southeastern Alberta and western Saskatchewan, with the infestation somewhat diminished in western Alberta.

The grape leafhopper was extremely prevalent in the grape sections of Ontario in 1922. Leaves, weeds, grass, and rubbish, in neglected fence rows, are providing satisfactory hibernation quarters for the adults which have not been reduced apparently to any extent by winter. A noticeable migration is expected to vineyards in the middle of Iay with favorable spring and early surnver weather conditions. The species concerned in last year's outbreak were Erythroneura cores Say, E. tricincta Fitch, E. vulnerata Fitch, and the varieties of cores, viz: Vit Harr. and ziczac 7alsh.

The rose-chafer occurred in severe outbreak form in several sections of
Ontario during 1922, the greatest numbers being present in the sandy 7rape-growing areas of the Niagara Peninsula. It is not possible to state to what extent this
insect will be present in 1923 but winter conditions have not been unfavorable to its successful hibernation.

The forest tent caterpillar will doubtless again occur in outbreak form in
New Brunswick, particularly over the southeastern portions of the Province, judging 'rol the number of egg masses now present. Spring frosts in the past have had a
-y marked influence in controlling this insect and it is possible that this save influence will reoccur this year. The outbreak of the orchard tent caterpillar which assumed important proportions in 1922 in New Brunswick may also continue dui ing this coming season, particularly in the St, John River Valley.

INSECT PEST SURVEY BULLETIN



Vol. 3 April 1, 1923 No. 1


CEREAL AND FORAGE-CROP INSECTS

Z T

CHINCH BUG (Blissus leucopterus Say)

Illinois 71. P. Flint and assistants (March 20): From 97 to 9S per cent of
the bugs in winter quarters throughout southern and central Illinois
are still alive. The winter has been milder than the average and only from 2 to 3 per cent of the bugs died during the winter. 77e
expect from moderate to heavy infestations in about 65 counties this
spring.

Nebraska M. H. Swenk (Harch 10): The chinch bug seems at this time quite
threatening in the southern part of the tier counties along the
southern border of Nebraska, from Jefferson County 7'est at least to Furnas County, and in the northeastern corner of the State in Boyd
County, the latter being a southward extension of a serious infestation in southeastern South Dakota.

Kansas E. G. Kelly (January 29): Chinch bugs seem to be more abundant than
during average years. The temperatures have been above normal and
very dry. Burning of hibernating quarters is being practised throughout the State.

HESSIAN FLY (Phytophaga destructor Say)

Nebraska M. H. Swenk (March 10): In spite of the dry summer and fall in 1922
the Hessian fly seems to be still quite numerous in early-sown winter
wheat in some parts of eastern Nebraska. A field in Dodge County
examined in the middle of January contained on the average five
puparia of this insect to each wheat plant.

California C. M. Packard (March 7): The Hessian fly is present in considerable
numbers bordering San Francisco Bay, and in a region in the northern
part of Monterey and San Benito Counties and the southern part of
Santa Cruz County.

GREEN BUG (Toxoptera graminum Rond.)

Kansas S. J. Hunter (January 15): Mr. Beamer has completed a survey of the
southeastern tier of counties of Kansas and finds no evidence whatever of the green bugs; this region, owing to the unusual drought
last August, had no volunteer grain.

G. A. Dean and J. 71. McColloch: Mild winter and a backward spring
followed by excellent growing conditions have materially reduced the
amount of green bug in the western part of the State.

-7-











E. G. Kelly (January 20): A few adults were observed in Pontgoerory
and Labette Counties. They have already started to multiply.

Oklahoma J. R. Horton (January 23): Mr. H. H. "alkden has found three fields
infested with the green bug in small colonies in Noble County. The
largest of the injured spots measured 20 feet in diameter. No
evidence of parasites was found, but adults of Hicrrodaria conversens
were moderately numerous. (January 291: Thirty-six wheat and
volunteer oat fields were examined in Oklahoma, Logan, and Carter Counties. In Carter County no aphib of any kind were observed; in Oklahoma aphids were found but none of then were Tcxottera; in
Logan County one wheat field was infested with the green bug. This
field was very thoroughly infested and covered 20 acres.

Louisiana T. H. Jones (February 1): A few small areas in oat fields at the
Louisiana Experiment station showed damaged by the green bug on this
date, the oats being stunted in growth h and of a brownish color.
material determined by Dr. A. C. Baker.

Texas E. E. Russell (January 5): Found two heavily infested spots in heat
fields near Celina, Collin County. The first of these spots was
noted by the farmer on December 21; by January 5 this sot was entirely bare. Parasitized species wre quite plentiful. Syrphidae and Coccinellidae were also present. This field was lightly infested last year. Examinations of fields in northern Dallas, Collin, and Grayson Counties failed to show further infestations.h (January 2 the
T-o additional fields have been found to be infested withireen bur
in Grayson an.d nothern Collin Counties.

C. H. Gable (February 21): The winter has been exceptionally mild followed by a cold snap, t February 3 the temperature reaching 2 degrees at San Antonio. The past sunmrer w-as unusually hot and dry :,ith practically no volunteer growth of grain until late in the
fall. Toxoptera are in such numbers that it does not seem possible that they passed the surrer on native grass. The general 7reen busituation does not appear to be alarming, although there is sufficient infestation to cause serious injury should there be unusually
favorable weather conditions for the develop rent of the a-hids.

New Pexico R. L. 7iddleorcok (:arch 11): This insect has damaged about 10 nar
cent of the wheat in Dona Anna County. Parasites have not as yet
appeared.

GRF!T PLAINS FILSE mlR"oR" (Elecdes oaca Say)

Nebraska M. H. Swenk (March 10): In Nance County early in November the areat
Plains false wireworm as injurious in the wheat fields, one farmer
suffering a loss of dn entire field that -as sown the last of August.








CORN

CORN EAROIREI (Heliothis obsoleta Fab.) Nebraska M. H. Swenk (March 10): In November our attention was drawn to a
cornfield in Scottsbluff County that had been extensively damaged
by a combination of the corn leaf aphid and the corn earorm during
the siurer.

ALFALFA PND CLOVER

CLOVER-LEAF "TFYIL (Hypera punctata Fab.) Illinois 7. P. Flint (:arch 20): The larvae of this species are more than
usually abundant in southern Illinois. Very little feeding has
been done as yet as the eaterhr has been cold.

LESSER CLOVEIR-LEAF "TEVIL (Phytonomus nizrirostris Fab .)

Illinois YJ. P. Flint (March 20): Adults of this species are tore abundant
than has ever been the c~se before throu-hout southern and northern
Illinois. IYe anticipate rather heavy damage from this insect during
the coming season.

LEAFFOPPER (Stictocenhala festina Say) New Mexico R. L. Middleorook (March 11): This insect is more plentiful than
usual in the Pecos and Rio Grande Valleys where it is attacking
alfalfa.



FRUIT INSECTS

APPLE

APHIDID PE

Illinois S. C. Chandler (!'arch 17): Aphid e.-s are fairly abundant in southern
Illinois in a few: localities. As a -hole, they are not generally
numerous.

ROSY APPLE APHID (Anurarhis roseus Baker) Connecticut Philip Garman (March): Many omws noted in New Haven County.

CODLINTG MOTH (Carpocapsa pcmonella L.) New Mexico R. L. Middlebrook (March 11): This insect was observed as some-.T;hat
abundant in Dona Anna County.

FRUIT-TREE LEAF-ROLLER (Cacoecia aravrospila Walk.)

Idaho D. B. 7helan (March 1): The following counties are known to be infested on this date: Bonner, Kootenai, Nez Perce, Adams, Gem, Canyon,
Twin Falls, and Madison.









SPRING CANKEROR,, (Paleacrita vernata Peck)

Eissouri A. F. Satterthwait (Harch 9): Moths were flying at extension lights
at Webster Groves until about 8 or 8:15 p. m. None seen after 8:15.
Elms are common here, but I do not know of cultivated apples close by. .est
Virginia L. 1A. Peairs (March 13): Adults, male and female, observed on and near
apple trees in considerable numbers.

APPLE MAGGOT (Rhagoletis pomonella "alsh)

Maine E. !. Patch (Iarch 15): One correspondent from Brunswick reports that
his apples were completely destroyed by this insect last year.

SAN JOSE SCALE (Asoidiotus oerniciosus Const.) Rhode
Island A.E. Stene (Yarch 15): This insect, though not found in large numbers,
is apparently on the increase in the northern section of Rhode Island.

Ohio T. H. Parks (Iarch 23): Several growers in Laurence County complained
that the San Jose scale is increasing in spite of careful spraying
with lime-sulphur solution. 7'e note that this scale is worst in an
orchard that did not receive the dormant spray in 1922. In this
orchard much fruit was ruined by the insect. Well sprayed orchards
also have some. Approximately 40 per cent of the over-intering scales
are now dead from natural causes other than parasites. Some parasitism
exists among the scales.

Illinois W. P. Flint (1:arch 20): Large percentage of unsprayed scale found
alive, 60 to 80 per cent. Many orchardists are changing from limesulphur to lubricating-oil emulsion sprays, as there is general dissatisfaction in the southern half of the State.

Idaho Chaude Wakeland (March 16): Very heavy infestations of the scale on
willow along the shores of the Snake River and on islands in the River.
Fruit orchards adjoining are repeatedly reinfested from this source.
Scale generally scattered in apple orchards at Emmett and Parma with here and there heavily encrusted trees in many of the best cared for
orchards. In Boise this pest occurs on currants, pear, cherry, aPTple,
and rose.

Texas 1. C. Tanquary (March 17): Serious infestations of the San Jose scale
have been reported from :ilam, Sabine County.

New Mexico R. L. Yiddlebrook (March 6): Infestation by the San Jose scale seers
to be particularly heavy in the Pecos Valley and a sample wvith the twigs badly encrusted was received from San Juan County, where our
records indicate that heretofore it has been unknown. This county,
in the northwestern corner of the State, is very much isolated.

OYSTER-SHELL SCALE (Leridosaphes ulmni L.) Rhode
Island A. E. Stene (March): Reports accompanied by material have been received to the effect that entire trees are dying from the attack of
this insect.









Nebraska M. H. Swenk (Varch 10): During the winter infestations of apple
orchards by the oyster-shell scale were reported.

ROUNDHEADED APPLE-TREE BORER (Saperda candida Fab.)

New Mexico R. L. Middlpbrook (March 11): The roundheaded apple-tree borer is
more numerous than usual in Dona Anna County. Another species lacking the stripes of candida is also occurring in great numbers in this
County.

EUROPEAN RED VITE (Paratetranvychus oilosus Can. & Fanz.)

Connecticut Philip Garman (March): A great many eggs may be found in orchards in
New Haven County, where no injury was noticed last summer.

Maryland E. N. Cory (Yarch 27): Scattering infestations are to be found at
this time in the egg stage.

Ohio H. A. Gossard (March 22): The European red rite has been found distributed over rost of northern Ohio. Eggs of this species are very
abundant in apple orchards in Mahoning County west to Lucas County
and southward as far as Delaware County. It is probably distributed
all over the State.

CLOVER VITE (Bryobia praetiosa Koch)

Idaho Claude Wakeland (March 16): Very heavy infestations at Parma and
Roswell of eggs, indicating that injury may be expected this season.

PEACH

PEACH BORER (Aeeria exitiosa Say)

New York G. 1. Codding (March 20): Practically all peach trees in Westchester
County are infested. Have taken from 8 to 10 borers from one tree.
Have never seen as many before.

SHOT-HOLE BORER (Scolytus rugulosus Ratz.)

New Mexico R. L. Middlebrook (March ll): This insect is present, but notserious,
in Dona Anna County.

PLt CURCULTO (Conotrachelus nenuphar Hbst.)

Georgia 0. I. Snapp (March 5): The first adult curculio was taken from a
peach tree early this morning while jarring. A few peach blossoms
just beginning to appear. Beetles will be appearing in numbers from
hibernation by the tire the trees are in full bloom.

Louisiana T. H. Jones (March 17): Observations made today on a few peach trees
on which abundant fruit has set; some fruit having reached a diameter
of 3/4 inch failed to show any evidence of the curculio.








PEACH-TTIG MOTH (Anarsia lineatella Zell.)

New Mexico R. L. IHiddlebhook (March 11): This insect has been observed in
Dona Anna County.

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

Georgia 0. I. Snapp (March 10): Homemade engine-oil emulsion has given
excellent control of this insect, and to date no injury to peach twigs has been discerned from the use of the 2 per cent emulsion.
Liquid line-sulphur has given only fair control, and the dry materials in many cases poor results. Cra 'lers have been found each
month during the winter, proving that full-grown females are living through the winter in the 5outh. These mature scales are difficult
to kill with the lime-sulphur. Had low temperatures occurred in
middle Georgia during the past several winters the full grown females,
in all probability, .:ould have been killed and scale breeding during
the winter prevented.

PEC PN

PECAN CASE BEARER (Acrobasis hebescella Hulst)

Texas A. I. Fabis (!.arch 14): Seasonal conditions are very favorable to the
production of a large pecan crop in the semiarid section of Texas.
Acrobasis hebescella hibernaculas are, however, unusually abundant
this winter, and unless parasites check the ravages of this pest the
pecan crop will be very short.

GRAPE

GRAPE CANE-BORER (Imohicerus bicaudatus Say)

SWEET POTATO WEEVIL (Cylas formicarius L.)

Louisiana T* H. Jones (January ll). "Mr- W. E. Anderson, entomologht
of the State board of agriculture, reports weevils as being very abundant in a storage warehouse at Stevensiale- later
investigations by Mr% C. E. Smith, U. S- Bureau of Entomology,
showed potatoes in this house to be of the 1921 crops The
weevils had, apparently, been introduced at Stevensdale
through infested material brought here from elsewhere and
had, apparently, been spread to various farms in that section
through this materialCABBAGE AYD KOHLRABI

WESTERN PINE BEETLE (Denlroctonus brevicomis Lec.)

California A. J. Ja-enicke (Decencer, 1922): This beetle killed 33,000,000
board feet of timber in 1921 over an area of 430,000 acres in the Modoc National Forest. Plans are now bein- considered to
combat the pest on this area. The xz-ige amounts to over
$1o.0o00.

J. IMiller (Dec-ber,1922): This beetle killed 100,000,000
board feet of timber over an area of about 300,000 actes
in the California National Forest lurinz 1921. The loss amounted
to at least $300,000 and vwas very conspicuous, whole hillsides
appearing red as though swept by fire.

Oregon A- J* Jaenicke (Decedater 1922): This insect killed 40,060,000
board feet of yellow pine value at $120,180 during 1921 on the
area surrouning the control project in southern Oregon (Klarath
and Lake Counties), coverin- 3,370, acres. This loss is not
much above ithe normal and approachts one-fourth of one rer cent
of the stand each year.

F. K. Keane (March 12): On the control project
this insect killed 91,961,000 board feet of limber in 1921,at
an estimated value of $275,883- This was determined by a
5 per cent cruise of the territory, -which included 1,250,000
acres of forested land. A cooperative control project is now
under way to curb this loss.
