H MOR IMPORTANT RECORDS FOR JUNE, 1923
The grasshopper situation in the Dakotas, Minnesota, and eastern LMonTana is as serious as was anticipated from the surveys carried on last year. Extensive campaigns are beina carried on throughout the infested districts. Scattered outbreaks were also reported from Iowa and Nebraska, and southward through Kansas and Oklahoma to Mississippi and Texas. Outbreaks are also reported from localities in Wyoming, Utah, and Nevada. In the upper Mississippi Delta airplanes were used in attempting to control the outbreak of hon ers.
The black cutworm, or so-called overflow worm, developed in outbreak
numbers in the lowlands of southwestern Indiana, Illinois, and Ohio. The claybacked cutworm occasioned serious injury in central and northern Illinois, the pale western cutworm was troublesome in northeastern Colorado and north-central North Dakota, and the variegated cutworm has been reported from Virrinia, Tennessee, and Missouri.
Toward the end of June considerable outbreaks of armyworms were reported from Pennsylvania, Virginia, West Virginia, Indiana, and Tennessee.
The garden webworm was reported as destroying alfalfa in parts of Indiana, and a general and rather severe infestation of webworms on both sugar beets and alfalfa was reported from Minnesota, Montana, Wyoming, and Utah.
An unusual and severe infestation of crotalaria by the bella moth was reported from Georgia through Alabama to Louisiana.
Rose chafers have been unusually and distructively abundant in the New England States and westward through New York to Indiana and Michigan.
-Despite the setback the chinch bug received during iay by heavy rains,
this insect was reorted as still appearing in serious numbers in Ohio, through Indiana to central Illinois, and in -narts of Iowa, Missouri, and Nebraska, southward through Kansas to Oklahoma and Texas.
The lesser corn stalk borer was reported during the month as dma~ring both sugarcane and corn in the Gulf States from Louisiana to Georgia and Florida.
The codling moth is very ab 'ndant throu-hout the Eastern States. The
infestation in Illinois is reported as the most serious in the past 20 ycars.
The rosy apple aphid built up destructive populations during :aly June in the 1 idle Atlantic States.
Blister beetles, which in the gr-o stage are predacious on ?rass.o er egos, were reported as unusually destructive to truck corns in the Sou:h Atlantic States, from Virginia westward to Kentucky. In the region heavily infeste. by grasshoppers last year these insects became decided nests to both field and garden crops, reports having been received from the two akotas, Nebraska, Kansas, and Wyoming.
The false chinch bug was very abundant during the middle of the month in the "est Central States, reports having been received from Iowa, lebraska, and Kansas. It was also reported from Colorado, Utah, and California. In California the outbreak is the worst ever recorded.
The Mexican bean beetle continues to be seriously abundant throu hout its entire range.
Brood XIX of the periodical cicada, the largest of the 13-year broods,
appeared during late May and early June over the greater part of the territory known to be infested. This brood covers the territory from central Illinois anod northeastern Missouri southward over Arkansas and eastern Oklaho.ma to the northern border of Louisiana and extends eastward across Tennessee and Alaba.a into Georeia and the Carolinas.
Fall and spring canker worms were generally prevalent from the New England States and New York westward to the Dakotas and Nebraska.
The forest tent caterpillar is abundant throughout the mountainous regions from Maine southward to ce:.tral Virginia. An outbreak of this insect is also reported from northeastern Colorado.
THE MOST IMPORTANT ENTOMOLOGICAL FEATURS IN C0AADA FOR JUE 1933.
Over a large part of the Dominion the spring season was cool and late, and work on the land and seeding operations were reported more backward that in any year since 1928. A report at the e::d of May stated that throughout the West 'eneral soil-moisture conditions were better than for several years. However, in June there were complaints of shortage of moisture in certain areas of the Prairie Provinces and more precipitation would be welcomed, particularly in west-central Saskatchewan and in southwestern anad ceral Alberta.
In .encral, reports from various parts of eastern Canada and British Columbia indicate that insect damage to field and fruit crops, so far, is comparatively licht. In the Prairie Provinces the hatching of erasshop ers was e..eral by the first week in Jurne over considerable areas and, as expected, an outbreak of serious proportions was developin-. Strenuous efforts to cope with this outbreak by m-us of poisoned baits are beinr made.
C utworns ap -ared to be less t',reatenin, in :he Prairie Provinces man d:rin: the oast few: years. Local losses due to the pale v:estern cutvorm occurr: in Alberta and at various points in central :-.1 east-central S:osh t ewan, but in both PrFvincs the outbreak of this species was generally 1. a severe tan in 1932. Exc~ptionally few com-laints of cutIL orm uuje nave bec: .:e in the Okanav-a Valley, British Columbia, but considerable trouble
from these insects was reported from the Kamloops district. Some truck and garden crops in southern Quebec were seriously attacked by cutworms, and local damage by several species occurred in some sections of Ontario.
Extensive damage to grain by wireworms was reported in Alberta and in the Assiniboia-Swift Current area of Saskatchewan. Local damage by wireworms was noted in eastern Ontario.
Injury by ihite grubs is already heavy in eastern Ontario where beetle
flights occurred in 1932. The damage will reach its maximum this year in the autumn. White-grub infestations were reported from southern Quebec and southern New Brunswick.
Flea beetles have again proved troublesome on truck crops in parts of British Columbia, and on garden truck and sugar beets locally in southern Alberta and Saskatchewan. Local damage by flea beetles was also noted from Ontario and southern Quebec.
The cabbage maggot has caused some damage in the Okanagan valley, British Columbia, and root maggots are generally abundant on irrigated truck farms in the Letlbridge area, Alberta.
Insect pests of the apple are generally less in evidence than usual in the Annapolis valley, Nova Scotia.
An unusually severe outbreak of grape leafhoppers is expected in the
Niagara district, Ontario, unless control measures are adopted. In this section, too, there is an outbreak of the black cherry aphid which is proving unusually
troublesome on sweet cherry.
Observations at certain points in the Niagara district, Ontario, indicate
that the population of overwintering adults of the oriental fruit moth was small compared with 1932. The spring brood was considerably smaller than that of last year and twig injury was reduced. It is too early to estimate accurately the final size of the generation.
Outbreaks of leaf-eating cater-rillars in certain parts of Ontario and in
the eastern townships of Quebec, were given much newspaper publicity in early June. Tent caterpillars and canker worms apparently were the chief species concerned. A heavy infestation of cankerworms also extended alon5- the Red River valley, Manitoba. A decided increase of tent caterpillars was evident throughout eastern Canada this season.
A general infestation of the willow leaf beetle developed in Saskatchewan and Manitoba, on poplars and willows, and n heavy larval infestation is likely to follow. Larch foliage was again severely attacked in Eastern Canada by the
larch case bearer.
In many parts of the Dominion mosquitoes and blackflies are proving :, more numerous and troublesome than during recent years. Severe infestations of mosquitoes have been reported in Quebec, Ontario, Manitoba, and British Collumbia; an unusual abun,.ance of blackflies have been noted in parts of Ontario, particularly in forested sections.
Recent reports indicate that among stored-product pests, spider beetles, Ptinus spp., are prevalent in many parts of the Dominion.

Cour.ty. If dry weather continues, we pect considearte damage to th c otton
fields located near -pasture land. So far 1. differentialis, which does .he
most damage in Oklahoma, itas not mradc ices ap-pearance in largo numbers.
Mississippi. C. Lyle (June 22): On June 15, -rasshoppers, chiefly M. cifferentialit
oe~e causing great dcmage to thousands of acres of corn, soybeans, and cotton at Parchman. In several field the cotton had been destroyed completely. The
hoppers seemed to prefer soybeans and had completely stripped hundreds of acres
of this crop. Most of the hoppers were about half grown or younger. All the
land had been broken during the winter, ditch banks closely plowed, and all
field margins cleanly cultivated, but there were myriads of the hoppers p resent
in spite of these preventive measures. Because of the necessity for quick action, three airplanes were being used to dust with calcium arsenate while
poisoned bait was being distriuted in iarge quantities. Lack of rain for two
or three months past increased the severity' of the outbreak.
Texas. F. L. Thomas (June 21): Grasshoppers are very abun-dant at Calvert and
Barstow, where they practically destroyed the cotton in a 10-acre field.
Montana. A. L. Strand (June 20): The northeastern counties in MIontana are suffering from a severe outbreak of the lesser migratory grasshopper, 1. mexicanus.
This outbreak centers in Valley and western Daniels and Roosevelt Counties.
Wyoming. C. L. Corkins (June 20): Grasshoppers are very abundant. The Bighorn
Basin has the worst grasshopper outbrea: in its history. Five cars of poison
are now out and the jo'b is about half completed.
Utah. G. F. Knowlton (June 15): Gr asshoppers are causing more or less damage in
various localities throughout the State. But in general the populations are
lower than at this time during the nst two seasons. arly nymphs of a few
species had become adults by June 9, in tre Grantsville Flux areas. Adults of M. mexicanus, X_. bivittatus, Trimerotro-pis vin-culata Scudd., and two other
species were taken.
Nevada. G. G. Schweis (May): G-rasshoppers of several species are reported as very
numerous in various parts of western Nevada. It is anticipated that control
measures will be necessary.
CUTOEMS (Toc tui dae)
Virginia. W. J. Schoene (June 23): Cutworms have been reported as injuring field
crops in sevral sections. Barley and rye were the main crops injured,
altho gh corn suffered to some extent. In some fields near Tirbervillc the darma'e to barley reached 90 per cent. Reports of injury were also received
from the bottomland on the James River east of Richmond.
Ohio. T. E. Parks (June 14): The black cutworm i.as destroyed 50 acres of corn
in Franklin County river bottom .land which overflowed in Iarch. It is not
present in upland corn. Larvae are nearly full grown now. Received specimens
also from Clinton and Fayette Counties with the statement that they had
destroyed 1/3 of the plants in a few fields. Also attacking corn at Columbus.

observed. Re-ports from, the vicinity of Fowler indicate th-at thnjuoands of acres
of corn nave been taken.
Illinois. 7. P. Fli-nt (June 19): Several species of cutworms have been causing
serious injury in- central and northern Il.1inois. In the lovi or overflo-w, areas
along- the rivers the darr,.&s-e has been caused mainly by th.-e black cutwona, A.
y~pslon. In the north-central part of the7 Stato many spring-plo ;ed ffields7
have beenr seriously doa~ged by the clay-backed cutworm, Feltia gladiaria 1Morr.
The se two species are by far the most destructive and abundant this year.
Tennessec. G. M. Bentley (June): A. ymnsilon and Lyco-hotia riargaritosa sauacia HIbn.
are very abundant in eastern aind ,iddle Tennessee.
North Dakota. J.A. 14uni'o (Jane 15): A report from B3antry (Mc~enry 0Volunty), June 5,
states that cutworms (Porosao-,rotis orthogonia 14orr.) are widespread anid. have

Nebraska. M. H-. Swenk (M1ay 2o June 20): Cutworms hnve been reported as numerous
in G-arden County the last week in May and a lso in Dawcos County the midd le of
June. A cor.plai-nt concerning damage in alfalfa by'the 'dark-sided cutwormn
(Daxoa 'Hcola:.arr.) was received on June 3 from Perkins County. Num-,_-erous

Texas. F. L. Thomas (June 21): Cutivorr~s arc very ab uij,.it. and damagiing alfta1lfa.
ARMYWOPM (Cirthis unipuncta Haw.)
Pennsylvania. C. A. Thomas (Junc 21): A considerable outbreiak of armyworTs is now
occurring in southern Chester County, especially in the area between Wvest Grove and Oxford, along Route l. Six farms in this area were found to be more or less infested, one farm showing an 80 per cent reduction in barley because the worms cut off the heads. An unidentified tachinid fly laid eg;s upon approximately 25 per cent of the larvae in one field, but the parasitization in other fields
was very low. Starlings and crackles ate many of the larvae. Corn and alfalfa
.were also severely injured in some fields.
West Virginia. L. M. Peairs (May 26): Armyworms are numerous but scattered; they
are full grown.
Maryland. E. N. Cory (June 22): Arm worms are doing serious injury to barley,
wheat, and pastures in Kent,. Somerset, St.: Marys, Baltimore, Harford, Frederick,
and Washington Counties.
Washington, D. C. W. R. Wsalton (June 22): A heavy flight of armyworm moths occurred
last night, and many moths are flying about in buildings today.
Tennessee. C. Benton (May 26): Twenty acres of mixed barley and clover were
seriously injured near Petersburg, Lincoln Count'. Barley was practically all
cut off about an inch below the hcads. Crimson clover leaves are largely eaten
but the heads are undisturbed. Worms will be about full grown by Mlay 31.
SOD WEBWORMS (Crambinae)
Kentucky. W. A. Price (June 24): Sod webworms have been especially troublesome in
corn and tobacco fields. Many fields have one third of the crop ruined by these
Tennessee. C. Benton (M1,ay 31): Some damage by sod webworms to newly set tobacco
plants near Fayetteville, Lincoln County, is reported.
WRIS (Loxostege spp.)
Indiana. J. J. Davis (June 20): The alfalfa webworm (L. similalis Guen.) was
reported as destructive to alfalfa at Elkhart, May 31. There is indirect
information that this pest may have been destructive elsewhere.
Minnesota. A. G. Rug Tles (June 26): The sugar beet webworm is reported as bad in
Freeborn County on onions and in Redwood County on corn.
Montana. A. L. Strand (June 20): The beet webworm moths have been flying since the
last few days in May. Many eggs and young larvae are now present. An outbr..k,
somewhat less intense than that of 1932, is expected.
Wyoming. C. L. Corkins (June 20): Alfalfa webzorms are now hatching. There :ill
be spotted infestations of both the alfalfa and sugar beet webworms, but not
the general infestation of last year and not nearly so much damage.
Colorado. G. M. List (June 26): The alfalfa webworm L. cornixtalis 7alk. wintered
in exceedingly large numbers, but raiy
cae numbers, but rainy and cold weather which occurred just
a-fter er,-ier-ence started, so divided the brood and interfered witn eg-S layin.

ROSE CHAFER (Macrodactylus subspinosus Fab.)
Maine. H. B. Peirson (June): The rose c.,id'er was stripping cornfields at Augusta
June 17, and stripping roses June 20. It was stripping foliage of ash-leaf
maple, blackberry, gray birch, white birch, and willow on June 18 at Auiusta,
Portland, and Waterville.
New Hampshire. J. C-. Conklin (June 23): The rose chafer is fully as bundant as
last year. Several orchardists report injury to young apple trees. Severe
injury to each trees was also recorded.
Vermont. H. L. Bailey (June 26):- Rose chafers are very abundant. Reports have
come from Franklin and Washington Counties of particularly heavy outbreaks.
Massachusetts. A. I. Bourne (June 24): Probably the outstanding pest of the month
of June was the rose chafer. The first appearance in large numbers coincided with the hot, dry weather. The beetles were extremely active and caused considerable damage before garden,,rs realized that the pest was present. It has
attacked garden crops, small fruits, orchards (both leaves and the forming
fruit), and many ornamentals, as well as grape and rose. At the present time
the attack is lessening somewhat and the beetles are beginning to disappear, but it has proved to be one of the most severe attacks which we have had for several
years. Even in well-sprayed orchards it hes not been uncommon to find them
seriously gouging out forming fruits of apple and peach. Very often as many as
20 to 25 of the beetles have been collected on one peach. Numerous complaints
of the beetles attacking strawberry plantings, riddling the leaves and even
devouring the berries, have been received. Raspberries and blackberries have
been attacked very severely and the pest has even been found to riddle the
foliage of poison ivy. It might be of interest to note that in one field in Agawam, in central Hampden County, the rose chafer was observed early in June
to be on the whole more destructive to the beans than was the Mexican bean
Connecticut. W. E. Britton (June 23): M. subspinosus is more abundant than usual
on apple, peony, and rose at New Haven and Watertown.
New York. P. J. Parrott (June 20): The rose chafer is very abundant fro: Albany
C. H. Hadley (June 23): The rose chafer is abundant at Westbury,Long Island,
especially on roses and viburnum, and conspicuous defoliation has been observed.
In some cases 25 per cent of the foliage of viburnum has been destroyed.
Indiana. J. J. Davis (June 20): The rose chafer was dmTaging apple fruits at
Evansville, May 29.
Michigan. R. Hutson (June 17): The rose chafer is moderately abundant.
Pennsylvania. C. A. Thomas (May 29): The wet weather during May has been very
favorable for wireworms. Thousands of Pheletes agonus Say larvae w ;re found to
be damaging cabbage:, corn, seed potatoes, rutab7-as, etc., in Bucks nnd oter southeastern counties, while in the western part of the State the chief injury was done by larvae of Agriotes:mancus Say and Melanotus sp. (June ) Wir

o a field of si ri.-,j7 bar ey
to a cornfield joining. About 1/3 of the corn was already plastered with bugls.
This locality has suffered from droughY.t. Today we learned of a similar outbreak
in Delaware County.
Indiana. J. J. Davis (June 20): Chinch bugs are moderately abundant in isolated
localities. They were reported as heavily infesting a barley field at Earl
Park, June 13.
Illinois. W. P. Flint (June 19): In spite of the heavy rains during all the
early part of May, sufficient numbers of chinch bugs survived to threaten injury
over about two-thirds of Illinois. The extreme northern and southern parts of
the State will escape injury. Many cases have been reported of fields that
became grassy and were later plowed and planted to corn, where the bugs are now
killing the corn.
Iowa. C. J. Drake (June 19): The chinch-bug situation is.becoming quite serious in
southern Iowa. The infestation includes the two southern tiers of counties from
Page to the Mississippi River. Several fields of small grain and a few fields
of corn have already been plowed up and planted to soybeans. In a number of
instances the first-generation bugs are feeding in the cornfields. The present infestation is more serious and widespread than the outbreaks in 1924. Weather conditions this spring and summer have been very favorable for the chinch bugs.
Missouri. L. Haseman (June 24): Chinch bugs are doing considerable damage to wheat,
oats, and barley, moving to corn last. The infestation is worst in the northcentral part of the State.
Nebraska. M. H. Swenk (June 20): The center of greatest abundance seems to be
Lancaster and Saline Counties, but the bugs are more than ordinarily plentiful
over much of southeastern and southern Nebraska. A report from as far to the
northwest as Boone County indicates that they were locally abundant there.
Owing to the early drying-up of the barley and oats, the migration started
shortly after the middle of June, w which is earlier than usual in this locality, and was at its height on June 20. Considerable damage to corn will undoubtedly
result from the chinch bug depredations.
Kansas. H. R. Bryson (June 22): Chinch bugs are more injurious at Manhattan and
surrounding territory than they have been since 1927. A considerable infestation
occurs in corn and sorghum fields as a result of old buns laying es;s at the
bases of the corn plants. Migrations from the small-grain fields to the corn
and sorghuns began about ten days earlier than normal. This condition was
occasioned by the hot, dry weather, which hastened the maturity of wheat, oats,
and barley. Counties in the eastern part of the State, which have received
heavy rains during May and the first part of June, have less injury. Reports
of injury have come from Canton, Meriden, Howard, Willard, Elk Falls, and
various points in the vicinity of Manhattan.
Oklahoma. C. F. Stiles (June 13): Chinch bugs are still very numerous in the eastcentral part of the State, with the center of infestation at the present time around Sapulpa, in Creek County. Some of the sweet corn in the city gardens
located near wheat fields are being destroyed by chinch bujs mi ratic from ther fields. Corn and other row crops are being heavily infested by mi.:rating chinc
bugs, in 10 counties at the present time.

N. Y. State Coll. of Agr. News Letter (June): Hot weather durin- the second
week in June accelerated egg hatching in both the Hudson River Valley and
western New York. Otherwise conditions seem acout normal. (Abstract, J.A.H.)
Delaware. L. A. Stearns (June 23): Sprin -rood emergence is about ended; firstbrood injury is generally much lower than that of 1932, 1931, and 1930.
Pennsylvania. H. N. Worthley (June 8): At Biglerville, Adams County, larvae were
first seen enterin,7 the fruit on May 28, and fresh entry was noticeable during the first week in June. High temperature is causing rapid emergence of moths.
The 50 percent point of overwintered brood emergence was passed during the first
week in June.
Ohio. C. R. Cutright (May 29): Emergence in orchards at Wooster started about
normal while cage emergence did not start till a week later. Owing to warm
weather the emergence has been rapid, with moths quite active.
Indiana. J. J. Davis (June 19): The codling moth is very abundant in southern
Illinois. W7. P. Flint (June 19): The codling moth is more abundant in most
orchards than at any time during the past 20 years. The weather on the whole
has been favorable for first-brood development. Larvae are now going under
bands throughout the southern two-thirds of the State. Second-brood hatching
is expected in the Johnson, Union, Jackson County areas July 4-5, with considerable numbers of worms hatching by July 7-8. In the south-central part of
the State the first hatch will occur in the Flora, Olney, Salem, southern
Calhoun County sections July 6-7, with hatch in numbers by July 10-12. In
central Illinois in the Adams, Logan, DeWitt, Vermillion County areas the first
hatch will be about July 10-11, with a considerable hatch by July 13-14. The
first-brood infestation is very heavy in many orchards, aud, because of the light crop and scabby condition of the fruit, it will bce necessary to spray
very thoroughly in order to control second-brood worms.
Wisconsin. C. L. Fluke (June 19): Codling moths are moderately abundant. The
first heavy flight of adults occurred June 9 and 10. Not so abundant as last
Missouri. L. Haseman (June 24): Indications are that we will have heavy broods
of late worms. Moths of the second brood are beginning to emerge in the southern part of the State. Pupating June 24 at Columbia and in northern :issouri.

which no spray or dust had been applied or other curculio control measures
enforced before the drops were picked u. Furthermore, the infested pea hes that fell during harvest last year were not removed from this orch-ard. (Jun.e

INSECT CONDITIONS IN PULRTO RICO
DURING SPRING OF 1933
Insular Experiment Station
San Juan Plant Quarantine Office
The citrus mealybug, Pseudococcus citri Risso, was exceptionally abundant
during the first half of June in citrus groves in the Bayamon district despite reasonably rainy weather. (G. N. Wolcott.)
Some months ago Pseudococcus nipae Mask. was noted so abundant on one avocado tree in-Rio Piedras, covering all the twigs and much of the larger branches, as to cause its complete defoliation; but the insects shortly afterward disappeared and the tree now appears normal. At about the same time the mealybug was very abundant on guava bushes and still continues to be rather common. I am of the opinion that this may be one of the delayed results of the hurricane,destroying the introduced ladybeetle Cryptolaemus montrouzieri Muls., none of which has been seen since. (G.N.W.)
The cottony cushion scale, IceryaDurchasi Mask,, has spread a few miles
farther to the southwest, being repoorted in the Bayamon district on the Comerio Road, and in the Espinosa district, between Dorado and Vega Alta. The ladybeetles have practically cleaned up most large infestations in San Juan, Santurce the Bayamon district, and Dorado, and have been found in the new infestations of the scale, having reached these by their own efforts. About 2,500 beetles were distributed this spring and have done good work except in small infestations and in exceptionally wind-swept locations. (G.N.W.)
The woolly white fly of citrus, Aleurothrixus howardi Quaint., is ordinarily
so scarce in Puerto Rico that infested leaves are curiosities, and never have I found more than one at a time. In a citrus .rove between Bayamon and Toa Baja, observed rather carefully recently, a dozen or more infested leaves per tree were noted on several trees. The owner reports having had his majordomos from this and other nearby groves bring him other similar leaves, indicating a rather unusual abundance of this insect. As it is usually kept so completely in control by parasites, its unusual abundance at present may be a belated effect of the
hurricanetal San Ciprian only now becoming aparent. (G.N.W.)
