THE MORE IMPORTANT RECORDS FOR JUNE
The grasshopper situation has developed to serious proportions in Colorado,
Montana, Nebraska, Kansas, Iowa, Wyoming, the Dakotas, Missouri, Oklahoma, Texas,
Arkansas, Illinois, with less general outbreaks in New Mexico, Arizona, Calif-
ornia, Minnesota, Wisconsin, Utah, and Michigan.
Along the Atlantic seaboard, from Maine to Georgia, localized wireworm in-
jury to potatoes, tobacco, and garden vegetables has been reported. On some
farms in the shade-grown tobacco section of Connecticut, loss of newly set plants
ran as high as 50 percent. Unusually severe damage to tobacco was also reported
from North Carolina. Limited serious infestations by wireworms were reported
from the East Central States and from Kansas, Idaho, and Oregon.
White grubs wore very numerous and destructive in the East Central States,
from Ohio and Michigan to Kansas.
Rose chafer damaged a wide variety of crops, occurring in outbreak propor-
tions in New England and the Middle Atlantic States, westward to Michigan.
In North Dakota the pale western cutworm has developed to such proportions
in the western part of the State that as high as 75 percent of the seeded crops
have been destroyed.
Localized outbreaks of the beet webworm are reported from North Dakota and
Utah, with an outbreak of the garden webworm in the easternhalf of Kansas.
The chinch bug, in general, is not seriously abundant.
Localized and serious outbreaks of armyworms occurred in Delaware, Mary-
land, and Virginia, during the early part cqf the month.
Two counties in NQrth Carolina--Edgecombe and Halifax--have been added to
the territory known to be infested by the vetch bruchid.
Peak flights of the codling moth occurred' during the last week in May and
the first week in June in the Hudson River Valley, N. Y., the infestation in
this area being much heavier than last year. Moths of the first generation be-
gan emerging in Georgia during the second week in June. The spring-brood flight
in Yakima Valley, Wash., reached its peak during the last week in May, which is
about 10 days later than in 1936,
The eastern tent caterpillar continued to be a serious pest in the New
England and Middle Atlant.ic States.
Emergence of first-brood plum curculio from the ground was late this year.
Practically all of the earliest varieties of peaches have been harvested in.the
peach-growing sections of Georgia and were remarkably free from damage. This in-
sect is reported as being more abundant than usual in Mississippi and Texas.
Blister beetle injury was reported from the South Atlantic States and west-
ward around the Gulf to Oklahoma and Kansas, ....
Flea beetle damage to potatoes and garden vegetables was somewhat severe
over the New, England States, and New York and westward to North Dakota,
The aeed-corn- maggot has seriously damaged shade-grown tobacco kn nthe
Connecticut River' Valley, and a. variety of field and garden crops from New York,
through Michigan and Indiana, to North Dakota. Damage was also reported from
,An outbreak of the green stinkbug occurred about the middle of the m6oth
in. Alabama and Mississippi, the insects seriously damaging cotton, peas, beans,
and miscellaneous -truck crops. In Mississippi, the outbreak is said to be the
most severe ever recorded.
t 'Injury by the vegetable weevil necessitated 90-percent replanting in to-
mato fields in San Bernardino County, Calif.
The Mexican beap beetle is more ,abundant than it has been during the last
2 years in -the New England States. The insect is generally prevalent throughout
the Middle Atlantic States and the lower Mississippi Valley.
Heavy infestations of the pea aphid were reported from western New York and
Long Island. This pest is also sufficiently numerous in northern Utah to require
SSquash bugs appear to be somewhat more troublesome-than usual in New Eng-
land, Middle Atlantic, and South Atlantic States. Damage was also reported from
Mississippi and Kansas.
-Very heavy outbreaks of the asparagus beetle were reported from Massachusetts
and New York.
A heavy outbreak of tobacco flea beetles occurred in the Piedmont sections
of Virginia and North Carolina, southward to Florida, and westward to Tenr.essee.
The cotton flea hopper is generally reported from the Cotton Belt. In
parts of Texas this insect, is attracting more attention than the boll weevil.
The cotton leaf worm appeared about'. 2 weeks later than last year in south-
ern Texas. The first worms were found in Nueces County on May 27, in Calhoun
County on June 9, and in Jim Wells County on June 19.
,Thrips: injury to, cotton has been reported generally from South Carolina to
The forest tent caterpillar caused considerable complete defoliation of
forest trees in the New England and Middle Atlantic States, and westward to
Eggs of the gypsy moth started hatching in Maine and New Hampshire early in
May. This insect is causing extensive and serious defoliation in many parts of
The larch case bearer %as severely injuring larch in New England and
eastern New York.
The anobiid beetle Platybregmus canadensis Fisher was reported to be dam-
aging flooring for the first time in the United States. It was originally des-
cribed from Ontario, Canada, in 1934.
THE MORE IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA
Hatching of the lesser migratory grasshopper was first noted in Manitoba
on May 10, Hatching of the eggs of this species and of the two-striped grass-
hopper was generally slow and irregular. Heavy rains early in June retarded
grasshopper development. No crop damage and no need for control measures had
developed by mid-June, but toward the end of the month the insects were causing
some alarm in southwestern Manitoba, and damage is expected if dry weather sets
in. In Saskatchewan the lesser migratory grasshopper began hatching in the
Estevan district on May 8. Egg mortality of this species was generally low.
The first nymphs of the clear-winged grasshopper were observed on May 10, near
Unity, Saskatchewan, and hatching was in full swing &n northwestern districts
by the end of May and was proceeding in stubble generally, although mole ir-
regularly. Fully half the eggs in all infested areas had hatched by June 1.
In western Saskatchewan an egg mortality of 60 percent of this species was ob-
served. Possibly a fungous organism was involved. By the third week of June
grasshopper hatching throughout the Province was practically complete. Devel-
opment was very irregular but more advanced in northern sections where adults
were beginning to appear. Up to mid-June, cool weather had restricted losses,
and control efforts were considered adequate where ckop prospects were good.
In Alberta hatching of the lesser migratory grasshopper began late in April in
light sandy soil areas in the Red Deer V-alley. Owing to uneven egg development,
the hatching period extended over several weeks. Itwas about 40 percent com-
plete. in east-central Alberta by May 31. Some crop losses had occurred early
in June, but those were checked by control measures,,and to some extent by
rains. Late in June grasshoppers were becoming more active, with hot weather,
but d-MnagC was still light. In southern British Columbia, in the Midway dis-
trict, the clear-winged grasshopper was hatching the last week of May and a
very heavy infestation has developed. The grasshopper situation is expected to
be acute in the Province this season, although the insects were late in hatch-
Reports of serious cutworm damage have been largely confined to the Pro-
vinces of Alberta and Saskatchewan. The pale western cutworm was causing injury
to fall wheat and rye at Lethbridge, Alberta early in April, the earliest re-
corded from that section. Towards the end-of June, damage was over for the sea-
son, with the most extensive crop losses in the Province in a decade. Heavy
damage was also done locally in Saskatchewan,. Another species, the army cutworm,
was more abundant in southern Alberta than at any time since 1928 on vegetation
of all kinds, but losses were generally light. Many of the larvae were destroyed
by disease. Hatching of eggs of the redbacked cutworm, at. Saskatoon, Saskat-
chewan, was complete by April 19, or about 12 days earlier than 1936. Cutworms
caused material loss in various localities in this Province.
Wireworms have been generally destructive in western Saskatchewan, es-
pecially in areas where crop growth was retarded by drought, soil drifting, and
frost. In Alberta, approximately 1 percent of the wheat acreage is reported to
have been destroyed. A recent survey in Manitoba indicated very little damage
by these insects. Throughout southwestern Ontario wireworms were reported to be
more numerous than usual.
Major flights of June beetles occurred in southern Quebec late in May and
locally in southern Ontario.. Third-year white grubs of this species are common
in many parts of. Ontario, where severe damage was done In 1936.
Asparagus beetles were unusually abundant in southern Ontario. In Niagara
district the greatest injury to the asparagus crop occurred late in May.
Maueh damage to young vegetable garden plants was done by the hop flea
beetle in southern Alberta.
o/ An extensive acreage of planted seed beans was destroyed by the seed corn
S maggot- in 'southern Ontario. '
Winter mortality of codling moth larvae appears to have been light in
southern Ontario and the Okanagan Valley, British Columbia.
Aphids are scarce in apple orchards of the Annapolis Valley, Nova Scotia.
The apple aphid, green peach aphid, and black cherry aphid are present in in-
juri.ous numbers in the Okanagan Valley, British Columbia.
The pear thrips has been found causing damage in orchards at Courtenay,
Vancouver Island, and at Kelowna, British Columbia, both new areas for this
The fruit tree leaf roller is increasing in many sections of the Okanagan
Valley, British Columbia, necessitating the application of oil sprays early in
Spruce mites have developed in outbreak proportions throughout the Prairie
Outbreaks of tent caterpillars occurred in'many' parts of Eastern Canada,
and were particularly severe in sections' of. Ontario and Quiebec,
Infestations of the fall canker wo'm were reported in New Brunswick,
southern Ontario, and the Prairie Provinces. It is reported that the shelter
belts on at least 10,000 square miles of land in central Saskatchewan are -very
severely infested by this species.
Ohio. T. H. Parks (June 24); Grasshoppers are present in no more than nor-
mal numbers. We anticipate no injury.
Ihdiana. J. J. Davis (June 25)?. Grasshoppers are showing up in unusual abun-
dance. Present indications are that they will be more abundant than
for many years in the counties adjoining Illinois and in the,northern part
of the State. The young hoppers were hatching aarly-in June.
Illinois. W. P. Flint (June 23): Grasshoppers are still hatching in the heavy
sod in the central area. The organized fight has been very effective,
and this, aided by heavy rains, has greatly lessened the threat of seri-
Michigan, Ray Hutson (June 19): Grasshoppers have practically all hatched.
Iowa. C. J. Drake (June 23): Grassho-pper infestation coincides very closely
with the egg survey, Baiting is being carried on extensively in the
western counties along the Missouri River. In the eastern half of the
infested area the young hoppers are hatching in large numbers. G. C.-
Decker reported this morning that he had never seen such heavy.infes-
tations of young hoppers as.he was now finding in Plymouth and Sioux
Counties. Melanoplus mexicanus Sauss., M. differentialis Thos.,
M. femur-rubrum Dog., and M. bivittatus Say are the predominating
Missouri. L. Haseman (June 25); Throughout southwestern Missouri the exces-
sive rainfall of the last 3 weeks has had a decidedly deleterious
effect on grasshoppers. Throughout central and northern Missouri and
in scattered areas throughout southern Missouri grasshoppers continue to
be threatening. In central Missouri the lesser migratory locust and a
closely related species or variety are already maturing and mating, and
the females at this time contain fully developed e;j-s.
Arkansas. Dwight Isley (June 21): There has been an outbreak in northern
Arkansas. The damage was caused largely by nymphs of M. mexicanus.
North Dnkota. F. G. Butcher (June 22): Grasshoppers are abundant, many
places having populations as high as 50 to 75 per square yard; gener-
ally in the third instar. M, mexicanus is decidedly predominating.
Crop injury being reported, particularly, to cereals and alfalfa.
Kansas. H. B. Hungerford (June 5): Young grasshoppers are more abundant in
places than we expected.
H. R. Bryson (June 23): Grasshoppers are causing injury over most
of the Sta7te. The population indicates that control measures must be
rigidly a-oplied to avoid serious damage. There is some evidence of
parasites and disease. The first adult migratory grasshopper was taken
on May 31, and the first adult of the two-lined grasshopper (M. bivit-
tatus) on June 16 in Riley County.
Oklahoma. F. A. Fenton (June 21): Grasshoppers have not been so destructive
as they were in 1936 and, the infestation is decidedly pore-spotted. M.-
mexicanus is now in the adult stage, and there are a few adults of M. bi-
vittatus and M. differentialis. TTe.most Severe infestation will pro-
bably be in the. panhandle section andi caused by Dissosteira longipennis.-
Thos.,' great number s'of Which are reported from Cimarron County.
C. F. Stiles (June 23); During the past 10 days the weather has
turned dry and the damage from hoppers "is increasing. The most heavily
infested counties-are in the southwestern part of the:.State. The pre-
dominating species are M. bivittatus, M. differential'is, and M. mexican-
us. The species most prevalent in the panhandle is D, longipennis.
H. T. Rainwater reports them there in enormous numbers. In one instance,
he reported secing.a line about 20 or 30 feet across and 3 miles long
that was practically solid with hoppers.
Texas. F. L. Thomas (June 5): Grasshoppers are causing considerable concern
in a number of counties.
. Montana. H. B. Mills-(June 24)t In many areas grasshoppers are extremely
abundant but rather .spotted.
Colorado. S. C. McCampbell (June 28): The infestation of grasshoppers, in-
cluding D. longipennis, is the heaviest in the history pf the State. We
are carrying on an intense control campaign: against D. longipennis.
Utah. G. F. Knowlton (June 17): Grasshoppers are seriously destructive in
s6me. parts of Utah. The cold, unsettled spring appears to be retarding
development although the nymphs and some adults are abundant in many
Nevada. G. G. Schweiss (June 18): Grasshoppers, have been reported as being
extremely numerous in/Lyon; Pershing, Washoe, and Elko Counties. Control
measures have been instituted in these counties. The outbreaks are ra-
ther limited in scope. Camnula pellucida Scudd. and M. mexicanus are
the species involved.
Arizona. C. D. Lebert (June 10): There was an extremely heavy infestation in
alfalfa and melon fields northwest of Phoenix.- M. differentialis was on
the margins of the fields and fence-rows and ditch banks. M. mexicanus
wa s destructive to alfalfa; estimated population of from 30O to 400
hoppers per square yard. Nearly total defoliation of alfalfa, and three
rows of melons gone. Some Trimerotropis spp. were present.
California. .S.Iiockwood (June 19): C. pellucida was found/damaging numbers
for the first time in the recollection of the writer in the Upper 'Sono-
ran zone in Merced County.
Tennessce. G. M. Bentley (June 1937): M. differentialis and M. femur-rubrum
are occurring in large numbers in several counties. This is the worst
outbreak in Tennessee for the past thirty odd[ years. Due to the dry
weather of last year large acreages of land, which could not be turned
in the fall, afforded ideal egg-laying areas.
L. B. Scott (June 21): The infestation continues to increase in
western Tennessee. All crops have. been damaged but tobacco and corn
have been most severely injured. Many fields, particularly of tobacco,
have been completely destroyed. M. femur-rubrur predominates.
Alabama. J. M. Robinson (June 19): On Juno l14 grasshoppers wore reported .to
be in large enough numbers to be considered -n outbreak in Limestone.-
County, in the central part of the State on the northern border.
We found that there were several species occurring in large numbers in
that area. Furthermore, grasshoppers are in abundance in central and
northern Alabama generally. The nymphs of;the lubber grasshopper, Ro-
malea mnicroptcra .Beauv., were reported as present in Birmingham on June
7 and in Talladega on June l4.
Mississippi. C. Lyle (June 24): Grasshoppers have been destructive to cotton
and soybeans in some areas of the-State, especially in the'Delta. M. fe-
mur-rubrum and M, mexicanus are the principal species involved,
MORMON CRICKET (Anabrus simplex Hald.)
Montana. H. B. Mills (June 24): Mornon crickets appeared as adults in the
Yellowstone Valley about June 5- Numerous adults were seen in Chauteau*
County June 22. They are extremely abundant and widespread throughout
Utah. C. J. Sorenson (June l1): Mormon crickets are very abundant in Juab,
Millard and Tooele Counties.
Washington. The Fresno Bee, Associated Press, (June 21)Mormon crickets are be-
ing fought with spray guns along a 35-mile trench line near Pasco,
Franklin County, in southeastern Washington. Sea gulls from the Paci-
fic coast have flown into the region and are devouring the crickets.
Maine. J. H. Hawkins (May 11): Agriotes mancus Say :
is present at the rate of 10 to 40 per square yard in fields at Knox,
Waldo County,..where potatoes were seriously injured during the past sea-
son. Both larvae and adults are present.
Connecticut. A. W. Morrill, Jr. (June 1): Limonius ectypus Say: In Hartford
County one oat field, formerly tobacco, was a 50 per cent loss. Many
tobacco fields needed resetting of small areas. One 5-acre shade tent
needed entire resetting.
"North Carolfina.- W. A. Shands (June 25): Reports have been received indica-
ting that wireworm,?injury on newly set tobacco has been. unusually se-
vere in the vicinity of Rocky Mount and over most of the eastern part
of North Carolina.- While not common, this injury has also been found
over the central part of the State. .
Georgia. 0. I. Snapp (June 17): Wireworms are more abundant than usual at
Fort Valley, central Georgia, and, have caused considerable damage to
vegetables. In .o-ne case they completely destroyed seven rows of onions.

Last.year corn yielded around 45 bushels per acre.
Kansas. H. R. Bryson (June 22): Injury by Melanotus spp. was more pronounced
this spring owing to the unfavorable sokl condition whi6h retarded ger-
mination of early planted seed. Reports of injury to corn and. wheat
have been received from the eastern .border of the".State,
Idaho and'Oregon. F. Shirck (June 15): xWireworrms have caused extensive in-
jury to sugar beets, having destroyed 30 to 60 percent of the plants in
many fields in southwestern Idaho and eastern Oregon. The unseasonably
coql weather has been favorable to continued feeding.
Oregon. H. P. Lanchester (June 21): A 30-acre field of peas 3 miles west of
SWeston was plowed under owing to injury by Limonius spp. .
;WHITE GRUBS (Phyllophaga spp.)

several infested farms have been abandoned.
Alabama. J. M. Robinson (June 19): In late May and early June the larva of
a curculionid was feeding on the underground stems of cotton and corn
plants, and the tubers of Irish potatoes in Covington County. It is
likely N. leucoloina. From the note on page 157 of the Insect Pest Sur-
vey Bulletin for June, we note that J. R. Watson reports the insect from

Missouri. L. Haseman (June 23); The variegated cutworm, combined with a
smaller number of the greasy cutworm (A. ypsilon)and more recently seem-
ingly the fall armyworm (Laphygma fruginerda S. & A.), developed along
with the recent armyworm epidemic. Relatively little cutting off of the
plants occurred but the cutworms feed rather like armyworms. The cool,
rainy weather prolonged the fccdinC.
North Dakota. F. G. Butcher (June 22): Cutworms are abundant in the eastern
counties and much damage to corn, other cereals, and gardens is being
F. G. Butcher (June 22): The pale western cutworm (Pores 'g-
rotis orthogonia Morr.) is exceedingly abundant and causing excessive
crop destruction west of Burleigh and Pierce Counties. Estimates of crop
:. .. 218-
destruction range from 10 percent i. Logan County-to i75percent in Stark

HESSIAN FLY (Pytop ag ostrUict6r Say)
Missouri and Kansas. E. T. Jones (May 1937): Limited surveys of fall-brood
hessian flies in southwestern Missouri and central, eastern, and south-
ern Kansas indicated only light, widely scattered infestations. Obser-
vations indicate very light infestations of first spring-brood flies over
ARMYWORM (Cirphis unipuncta-Haw.)
Delaware, L. A. Stearns -Jun 8)-: Serious infestation 'on, crops was noted on
whcat'land.cbrh at Taylors Bridge, New Castle County."'
Maryland' E. N. Cory (June ,4): -Two small outbreaks in Worcester County.
Virginia. D. W7. Jones (June 3): The highest infestation is in Northampton
County between Eastville and Cheriton. Pupation is well under way and
most of the remaining larvae are at least 1j inches long. The cement
road near the worst infested field is almost greasy from the caterpil-
lars that have been crushed by automobiles. One field showed an average
of nearly 200 worms per square foot. A pea field across the road, and
separated from it by two deep ditches showed an average of 10 worms per
running foot of row for 30 feet and was practically clean in the re-
mainder of the field (there was chickwood in the row with the pea vines).
An infestation nearly as bad was about 3 miles west in about 100 acres
of wheat and vetch. Stacks of cut straw about 6 feet in diameter showed
many worms in both Eastville and Cheriton. Some were up in the straw
but most of them were on the ground and in moist trash, especially about
a foot from the outer edge of the stack. In shaking the straw and mak-
ing square-foot counts in 20 places, the average was 182 per square foot
and seemed to run quite uniformly. Some pupae were noted in this situ-
ation and some cocoohs of a'braconid parasite. The farmcroads and
ditches showed frass and dead worms 1 inch deep in many places.
Virginia, A. M. Woodside (June 23): A heavy infestation was reported near
Timberville, in Rockingham County, on June 4. Barley was d.imaged pavily lr
the larvae which cut off many of the heads. Wheat was also damaged to
Ohio. T. H. Parks (June 24):, 'We are now in the midst of an- armyworm outbreak.
Injury first occurred in Butler County, southwestern Ohio, the second
week in June. It has continued uninterrupted but is now on the wane.
Some fields of fall barley have been almost entirely destroyed. A few
fields of rye have been seriously damaged and the new seeding of timothy
in wheat fields has been destroyed over a wide area. Wheat was not seri-
ously damaged. Corn was damaged very little. The larvae are now enter-
ing the ground and pupating. No moth emergence has occurred here. Heavy
moth flights from the South have been in progress the last two nights.
Last night I was called to-see"a cherry- tree where the ripening fruits had
been punctured by the moths which fed upon the fruits and destroyed them
in two nights* The moths were observed carrying out their destruction of
cherries. 7 .
Indiana. J. J. Davis (June 25): The armyworm has been the outstanding problem
of the month. The abundance of moths, followed by weather favoring the
rank growth of grasses and cool weather checking the activity of parasites,
was abundant evidence for anticipating the outbreak. First reports came
from Boonville, in the extreme southern end of the State, on May 29. There-
after reports were received of outbreaks and damage to timothy, barley, rye,
wheat, and corn from almost every county in the southern half of the State
and Ls far north as Rennselaer and Delphi. In the extreme northern end
of the State, in St. Joseph County, came reports of outbreaks on June 21.
Throughout the southern half of the State parasites are now abundant and
we expect will check any succeeding broods, although at Lafaybtte the
moths have been exceedingly abundant the past three nights.
Indiana. C. M. Packard (June 22): Moths were abundant last evening around
spirea bushes and ripening cherries at West Lafayette. One moth was
noted feeding on coreopsis blossom.
Illinois. W. P. Flint (June 23): A general outbreak occurred over the southern
three-fourths of the State, some damage occurring in every county. The
infestation was quite spotted, most of the damage being done to timothy,
bluegrass pastures, and corn. In only a few cases was the destruction
-complete. Warning of the outbreak was given a month ahead of the appeat-
Sance of the worms, so that counties were prepared to poison by the time
Kentucky. W. A. Price (June. 25): Armyworms appeared rather generally over the
central and western parts of the.State during the latter part of May and
the early part of June. Their attacks were centered largely on barley.
Iowa. C. J. Drake (June 23): The true armyworm is extremely abundant in the
State. Infestations have been reported in about 40 to 50 counties, where
small grain and corn have been destroyed.
Missouri. L. Haseman (June 23): As a result of the flight of moths from the
south early in May, we had, throughout the latter part of May and up to
June 20, probably the heaviest infestation of larvae that ever occurred
in this State. The infestation covered practically all of the State
east of a line extending from southwestern Missouri in a northeasterly di-
rection to near the middle of the St'-,to on the Iowa border. Some fields
of barley have been completely destroyed and damage was serious to fields
of wheat, timothy, and alfalfa, also to meadows and pastures. The larvae
began maturing about June 10 a.nd from Juno 15 to 22 the air was filled
with moths on cloudy days and toward sundown, as well as during the night.
As in the past, most of the moths have moved out presumably northward and
are likely to cause an outbreak in Northern States in July. The moths were
still abundant on the night of June 22 at Columbia.
KansasL. H. B. Hungerford (June 5): Army7orms have been very injurious
H. R. Bryson (June 26): Armyworms were abundant in the eastern
third of the State Juno 2.
Oklahoma.' F. A. Fenton (June 21): As expected, the armyworm outbreak subsided
and an interesting aftermath has benr- the enormous numbers of Calosoma
spp., which are very prevalent,
CHINCH BUG (Blissus leuco-pterus Say)
South Carolina. F. Sherman. and W. C. ':ettles (June 21): The chinch bug has
been abundant in York, Chester, and Lancaster Counties in the north-cen-
tral section of the State, having migrated from small grains nearby.
Alabara. J. M. Robinson (June 22): Specimens taken from corn following oats
at Livingston, on the western border of the State near the center.
Mississippi. C. Lyle (June 24): J. P. Kislbnko reported chinch bugs injuring
corn at Laurel on June 11. A complaint of damage was received from Soso
on June 21. A light infestation was r ported on corn -t Dirant by
D. W. Grimes.
Ohio. T. H. Parks (June 24): Heavy r-ins throughout June ha-ve greatly lessened
the chances of chinch bug injury. We have a report from only one county
where the bugs are said to be rather abundant. Before the rains they
were rather common in some fields of h:,-.t and spring barley. The new
brood began hatching during the second weck of June.
Indiana. J. J. Davis (June 25): Chinch bugs arc showing up in conspicuous
numbers from :.r.ny places in the western two tiers of counties from Greene
Iowa. H. E. Jaques (June): Chinch bugs are moderately abundant in southern
Kansas. H. R. Bryson (June 26): Scarcer this summer than 'for a number of years.
Only one report of injury has b en received. Barriers will not be re-
quired to protect corn.
Oklahoma. F. A. Fenton (June 21): In the northeastern part of the State the
chinch bug is apparently more abundant than at any 'time since 193'.
CORN EAR WORM (Heliothis obsoleta F.)
Virginia. A. M. Woodside (June 23): Moths were numerous in codling moth bait
pails for a week during the 'latter part of May at Staunton.
South Carolina. F. Sherman and.W. C. Nettles (June 21): The corn ear worm is
serious on vetch in tl'e Piedmont. It is also reported on cotton, corn, sor-
ghum, and fruit of tomato.
Georgia. 0. I. Snapp (June 17): The tomato fruit worm is very abundant this
year and has seriously damaged tomatoes at Fort Valley, central Georgia.
Besides damaging the fruits, they are even attacking.the vines'.
T. L. Bissell (June 8.): Serious injury t.o green tomatoes is reported
at Cuthbert and Pelham, in southwestern Georgia. One field was'a'total]
loss and had to be plowed up. At Griffin, in central Georgia, a severe in-
jury to 1 acre of tomatoes was reported. "Half-grown larvae are in the
fruit and blossoms and are occasionally boring into the stems. At Or-
chard Hill, in central Georgia, worms are two-thirds grown and are leav-
ing vetch to feed on small cotton leaves. (June 17): Larvae are eating
into seed heads of flax at Hawkinsville, in central Georgia. It is re-
ported that the loss of,-heads ranges from 3 to 5 percent. (June 22): In-
vestigated tomato infestation at Cuthbert, where the insect 'wvas causing
severe loss, bn June 7. Today larvae are very hard to find-saw two this
afternoon. The disappearance does not appear to be due to use of insec-
ticides, although much arsenical insecticide and some rotenone was used.
Indiana. J. J. Davis (June 23): The tomato fruit worm is very abundant, en-
tering green tomatoes in Gibson County in the southern end of the State.
This is perhaps earlier than usual and heavy infestations in tomatoes
and corn may be anticipated before the season is over.
Kansas. H. R. Bryson (June 22): Causing considerable injury to The curl'of'
corn. The larvae have been taken in tomato fruits.
Alabama. J. M. Robinson (June 19): The corn ear worm is active on corn, at-
tacking the ears of the older and the buds of the younger corn.
Mississippi. C. Lyle (June 24): The corn ear worm has been reported as caus-
ing heavy damage to tomatoes over the entire State. J. Milton writes that
one grower in Hinds County reported ar 25 % loss of his tomato crop.
Louisiana. C. 0. Eddy (June 25): Larvae have been very abundant the last month.
Birds have torn open ears of corn -nd fed on the larvae.
Texas. F. L. Thomas (June 22): Seems to be more abundant than usual in Cen-
tral Texas, probably because of the unusually dry weather and poor con-
dition of corn. Also reported on tomato, corn, and sweet peas in Gal-
veston County in May.
SOUTHERN CORNSTALK BORER (Diatraea crambidoides Grote)
South Carolina. F. Sherman and W. C. Nettles (June 21): The southern cornstalk
borer is prevalent, chiefly in the Piedmont section.
Florida. A. H. Madden (June 12): One field of corn in the eastern part of Gads-
den County had from 20 to 30 % of the stalks damaged. Other fields were
Georgia. T. L. Bissell (June 16): At Clarkston, in north-central Georgia;
three larvae were found in the leaves of one plant. (June 21): At
Milner, in central Georgia, a field of corn is beginning to tassel and
about one-fourth of the stalks are infested-none broken, but leaves ragged.
(June 23): At Cordele, in south-central Georgia, a field is beginning
to silk and about 10 percent of it is infested. Found one pupa in a stalk.
A WEBWORM (Crambus sp.)
Virginia. C. R. Willey (June 14): A species of webworm was noted on May 28
doing considerable damage on a 100-acre tract of land planted in corn on
the James.River, west of Richmond.
Kentucky. W. A. Price (June 25): Adults of sod webworms continue to be abun-
dant and the larvae have caused much damage to such cultivated crops as
corn and tobacco.
LESSER CORNSTALK BORER (Elasmopalpus lignosellus Zell.)
Georgia. Oliver I. Snappy (May 27): The lesser cornstalk borer is damaging young
corn at Fort Valley, central Georgia.
EUROPEAN CORN BORER (Pyrausta nubilalis Hbn.)
Connecticut. N. Turner (June 22): Eggs now hatching. Infestation in Housatonic
Valley very heavy. Preliminary observations in Connecticut Valley indi-
cate less egg laying than last year.
New Jersey. E. Kostal (June 26): Heavy infestation in rhubarb and sweet corn
at Morganville, in Monmouth County. Moderate infestation in potato stems.
SUGARCANE BEETLE (Euetheola rugiceps Lec.)
Virginia. C. R. Willey (June 14): Specimens were sent by a correspondent at
Laban, Mathews County, who said they are very numerous in cornfields in
his section and are doing lots of damage; also that there have been severe
infestations since the flood in this area in August 1933.
Mississippi. C. Lyle (June 24): The rough-headed cornstalk beetle has caused
considerable damqgo this spring. During the first half of June it was
reported injuring sugarcane, corn, and cotton.
CORN FLEA BEETLE (Chaetocnema pulicaria Melsh.)
New York. N. Y. State Soll. Agr. News Letter (June): The corn flea beetle has
heavily infested corn in Nassau County,- LQn .Island. vary plant shows
feeding marks and early wilt-resistant sweet corn has about 2 % wilt.
CORN ROOT APHID (Anuraphis maidi-radicis Forbes)
Kansas. H. R. Bryson (June 26): The corn root aphid has been reported as se-
verely damaging corn in D6niphan County.
'ALFALFA AND CLOVER
ALFALFA WEEVIL (Hypera postica Gyll.)
Nebraska. L. M. Gates (June 23): A survey being conducted in northwestern
Nebraska indicates a reduction in the numbers of alfalfa weevil in the
area. No new infestations have been found and some of the fields found
infested in 1936 were not infested this year, The development of the
species seems to have been delayed from a week to 10 days. Eggs, first-to
fourth-stage larvae, and last years adults are present in the infested
fields in northern Sioux County near the South Dakota and Wyoming State
Idaho. R. W. Haegele (June 16): The alfalfa weevil is ,about the same as in
1936 in southwestern Idaho. Infestations are spotted, with damage ran-
ging from negligible to about 20 % of the first crop. Larvae are ma-
ture and pupating, and the first crop of alfalfa is being cut.
Nevada. G. G. Schweis (June 18): The alfalfa weevil has caused some damage
in western Nevada. The counties affected most are Churchill, Lyon,
Washoe, and Douglas.
Utah. G. F. Knowlton.(June 10): In many northern localities damage is be-
coming more conspicuous.
California. A. E. Michelbacher (June'21): The alfalfa weevil population is at
a very low ebb. The average number of larvae collected to 100 sweeps of
an insect net in the infested area on June 14 ranged from less than 1 to
15, while the adult count ranged from 0 to 28. The population is the
lowest encountered for this time of the year since the investigation was
started in 1952. Parasitization by Bathyplectes curculionis Thos. on
May 28 ranged well above 90 % and in a number of cases was over 95 %.
CLOVER LEAF WEEVIL (Hypera punctata F.)
Indiana. J. J. Davis (June 25): The clover leaf weevil was destructive to
clover and alfalfa in DeKalb County the last of May and the first of
H. R. Painter (May 26): A heavy infestation by the two weevils H. punc-
tata and H. nigrirostris F. was seen in a clover field in Lake County.
Clover had been seriously damaged by H. punctata but at the time of ob-
servation this specie was almost totally destroyed by disease.
Illinois. W. P. Flint (June 23): Adults are now so abundant that they are in-
juring. the new growth of alfalfa where the crop has been cut.
Missouri. L. Haseman (June 23): During the middle of the month numerous com-
plaints came into the office that clover leaf weevils were destroying the
second crop of alfalfa. The complaints were usually accompanied by speci-
mens. The wet, cool weather evidently favored the maturing of the larvae,
resulting in an unusually heavy brood of adults. However, much of the
damage to alfalfa attributed to the weevil was done by cutworms and army-
Kansas. H. R. Bryson (June 22): Adults appeared in sufficiently large numbers
in certain alfalfa fields in the eastern third of Kansas to prevent new
growth following the first cutting.
Arkansas. Dwight Isely (June 21): There has been a serious local injury to
alfalfa in northwestern Arkansas, particularly in Boone and Carrel Counties.
GRASS THRIPS (Frankliniella spp.)
California. L. G. Jones (June 5): Alfalfa in the Antelope Valley was severely
damaged by the grass thrips F. occidentalis Perg. and F. moultoni Hood.
Seasonal conditions early in the spring were favorable for thrips to mul-
tiply in the grasslands throughout the valley and, as the vegetation
dried, the thrips migrated to the alfalfa fields. The migration started
about May 1 and by May 2S three-fourths of the leaves on the alfalfa
plants were badly deformed and somewhat skeletonized.
FIELD CRICKET (Gryllus assimilis F.)
Arizona. L. R. Stitt (June 22): Appear to be more numerous than last year in
the Yuma Valley, but there is no noticeable damage. The alfalfa seed crop
is developing and damage to the crop is likely to occur soon. Damage was
heavy in 1936 and was 80.5 % in 1934.
COWPEA CURCULIO (Chalcodermus aeneus Boh.)
South Carolina. F. Sherman and W. C. Nettles (June 21): Specimens of the cow-
pea pod weevil were sent in from various sections as injuring beans and
young cotton plants.
Georgia. T. L. Bissell (June 22): At Springvale adults appeared on string
beans and pods were punctured but no eggs were found. (June 23): At
Cordele, in southcentral Georgia, adults were thick on cow.pea plants.
Some were leaf feeding. One pod found with an egg and a small grub. None
on cotton at F6rt Valley, central Georgia, which was infested.May 27. The
stand was cut less than 5 %, not 20 %,-as I. reported'-in :the Insect Pest
Survey Bulletin, June 1937 (vol. 17, no. 4, p. J9l). At Experiment, cen-
tral Georgia, adults have been slow appearing on cowpeas but are now
moderately abundant. As yet there are no pods for them to infest.
THIEF ANT (Solenopsis molesta Say)
Kansas. H. R. Bryson (June 26): On May 27 the Kafir-ant (S. molesta Say) was
reported as destroying planted kafir seed in Douglas and Wabunsee Counties,
in east-central Kansas.
California. C. C. Wilson (June 9): In.May an unusual infestation occurred
near Wheatland, in Yuba County in, the Sacramento Valley, where this ant
Was noted as a pest of milo maize. Twot consecutive planting. of. seed
on 110i acres have been destroyed. Soil examinations were made and the
number of ants ranged from 10 to 4g per 2- feet of drill row.
VETCH BRUCHID (Bruchus brachialis Fahraeus)
North Carolina. L. J. Bottimer (June 26): On May 2 the writer collected
several adults on flowers of Vicia villosa at Princeville in Edgecombe
County, a'nd one 'on the same host pl-ant at Scotland Neck in Halifax
County. These collections add two new counties to the infested area
of the State.
SUGARCANE BORER (Diatraea saccharalis F.)
Louisiana. B. A. Osterberger (June 25): The sugarcane borer infestation in
the'Lafourche section of southern Louisiana in the corn, ranges from 45
percent to nothing, with an average of 10 percent; 34.3 percent of the
eggo collected parasitized by Trichogramrma sp.
L. 0. Ellisor (June 25): Examination of sugarcane in West Baton
Rouge Parish during the last 2 weeks showed that in some fields as high
as 5 percent of the plants were damaged by the first generation. This
represents'an average of about 1,700 borers per acre. On June 25, ll6
masses of eggs were collected in a field of corn. Of these 61 percent
were either wholly or partly parasitized by T. minutum Riley. No para-
sites have':been released in this field,
Texas. F. L. Thomas (June 22): D, saccharalis found in cornstalks throughout
May in Galveston County.
FRUI T INSE C T S
ROSE LEAF BEETLE (Nodonota puncticollis Say)
New York. N. Y. State Coll. Agr. News Letter (June): Rose leaf beetles began
emerging in the Hudson River Valley on June 1, a week later than the date
of first emergence last year. The third week in the month the beetles
were generally present and injurious in the orchards.
A LEAF MIIIER (Ornix geminatella Pack.)
Michigan. R. Hutson (June 22): The unspotted tentiform leaf miner is abundant
in two orchards in the vicinity of lonia, south of the center of the State.
This insect has been increasing in these orchards for the last 6 years.
CODLING MOTH (Carpocapsa pomonella L.)
New York. D. W. Hamilton (June 24): Moths began appearing in bait traps at
Poughkeepsie on the night of May 23. Heavy peak flights occurred from
May 30 to June 3 and daily captures have gradually decreased since. Ten
bait traps located in the same positions have captured 1,566 moths, as
compared- to 1,443 during the entire season of 1936. Entrances and stings
are much easier to find than they were at this time last year.
IT. Y. State ColL Agr. (June): In western New York the moths have
been active since May 30. Eggs were observed in Yates County oh June 11
and entrance first observed on June 18. Reports from other counties in
that part of the State indicate that the hatch has been delayed and en-
trances to the fruit are few.
Delaware. L. A. Stearns (June 23): The last emergence of spring-brood moths
took place on June 14. The earliest first-brood injury was observed in
an orchard on June 1 and injury was general by June 23.
Virginia. A. M. Woodside (June 23): The first larvae left the fruit in the in-
sectary at Staunton on June 17, and on June 18 the first i7cre'captured in
bands. Emergence of the spring brood of moths is complete in the insec-
tary, but moths continue to be captured in the bait pails.
South Carolina. F. Sherman and W. C0 Nettles (June 21): There is less dnmae
than usual, presumably because of the light crop of apples last year.
Georgia. C. H. Alden (June 23): First-generation moths have been emerging at
Cornelia, in northeastern Georgia, for about 10 days. Eggs are being laid.
Ohio. T. H. Parks (June 214): The first entrances were noticed in southern Ohio
on May 28, at Columbus on June 7, at Toledo June 8, and at Wooster June 10.
The insect seems to be well under control, as there are not very many
larval entrances in orchards that have received two cover sprays. Moths
are still caught in bait pails at Columbus and Toledo.
Indiana. J. J. Davis (Ju-h 25): The peak of hatching has been passed inall
parts of the State. Weather conditions during June have been less favor-
able for development than normal. ,
Michigan. R. Hutson (June iS): A general flight took place at Shelby on June 11.
Moth emergence has been rather scattered in other sections of the State.
Missouri. L. Haseman (June 23): There have been only a few days difference in
the dates of moth emergence in the south, central, and northern parts of
the State. A few scattered moths of the first brood are still being taken
in the bait pans throughout the southern and central.parts of the State and
larger numbers, particularly from. the northwestern part. We foundtho'
first evidence of first-brood larvae leaving fruit and spinning up under
the bands in southern Missouri last week. "
H. Baker (June 29): Thei6 first moths were caught in bait traps at
Saint Joseph on May 16, and peak catches were taken during the period
May 21 to 29, and catches have been light since June 8. The first attemp-
ted entrances were observed on May 29 and the first exit of a mature larva
from fruit was observed on June 17.. Catches of spring-brood moths were
heavier by far than at any time since 1934 but cool, rainy weather during
the period of peak moth activity held egg laying and larval activity to a
minimum.and feow first-brood larvae can be found in orchards.
Kansas. R, L. Parker (June 26): Moderately abundant in northeastern Kansas.
Washington. o E. J. Newcomer (Juno 19): The spring-brood flight in the Yakima
Valley reached its peak from May 30 to June 1, about 10 days later than
the peak in 1936. Owing to the cool, rainy weather, there has been very
little activity since that time.,
EASTERN TENT CATERPILLAR (Malacosoma americana F.)
Maine. H. B. Peirson (June): Hatching in southwestern Maiie was observed on'.
April 27 and tents were noticeable on May 5.
H. N. Bartlby (June 14): Serious injury is occurring in southwestern
New Hampnshire. J. G. Conklin (June 24): Cocoons of the eastern tent caterpil-
1ar were first observed on May 31 in southern New Hampshire.
Vermont. 7. E. Roberts (June 4): Nea.rly all the wild cherry that has not been
sprayed in Rutland and Addison Counties is completely defoliated.
Massachusetts. A. I. Bourne (Juno 23): The eastern tent caterpillar is again
very abundant with no evidence of any reduction in numbers.
Rhode Island. A. E. Stene (May 27): J-This insect is again showing up in un-
I/ -Tis note was incorrectly published on pag L-7. of tne Insect-Pest survy
Bulletin dated June 1, 1937, under J. J. Davis of Indiana.
usual numbers in some arts of the State, in fact, they are so abundant on
some trees that food is scarce and disease is making an inroad.
Delaware. L. A. Stearns (June 18): The first appearance of adults in New Castle
County, in northern Delaware was noted on :June 4. Disease is very preva-
New York. R. E. Horsey (June): These insects have completed their feeding and
are crawling around or forming cocoons at Rochester. The first cocoons
were noted on June 10.
Pennsylvania. R. M. Baker (June): A scourge of tent caterpillars occurs in a/
large area in the west-central part of the State, the infestation diminish-
ing around the area. In some sections; the larvae were so numerous on the
highways that they created traffic hazards.
APPLE APHIDS (Aphiidae)
Maine. F. H. Lathrop (Juno 22): In Kennebec County the first adults of the
second generation of Aphis pomi Dog. aopeared about June 1. This species
is more abundant than usual. Severe infestations developed in some young
orchards early in June. Anuraphis roseus Baker is a little more common
than usual. This species is not normally important in Maine.
New York. N. Y. State Coll. Agr. :Tcjws Letter (June): The rosy apple aphid is
causing some injury in the Hudson Valley and also in western New York.
Kentucky. W. A. Price (June 25): The rosy aphid is abundant in an orchard at
Nanty, Pulaska County, in south-central Kentucky.
Mississippi. C. Lyle (June 24): A correspondent in the northeastern corner of
the State reported A. pomi on apple on June 17.
Missouri. L. Haseman (June 23): Some evidence of the rosy apple aphid in or-
chards in central and southwestern Missouri, although less than usual.
Some increase of A. pomi but no particular damrage.
Idaho. R. W. Haegle (June 16): Early infestations of the grcen apople arohid and
the rosy aphid in southwestern Idaho have continued. Fruit has be..:.n
marked and new growth on young trees has been injured.
Washington. E. J. Newcomer (June 19): The rosy aphid is much more numerous in
the Yakima Valley than it has been for several years.
APPLE LEAFHOFERS (Cicadellidac)
Maine. F. H. Lathrop (June 22): A small proportion of the white apple leaf-
hoTroer (Typhlocyba Tonr-ria McAteo) was mature at Monmouth, in Keinebec CounA,
ty, on June 11. No heavy infestations found this spring.
Massachusetts. A. I. Bourne (June 23): Leafhop-oers arc aveoaring in about nor-
mal abundp-nce, but are later than usual and the infestation is lasting
longer. In most instances the lower half or two-thirds of the trees carry
the infestation and very few hoppers are to be found in the upper branches.
This year it was necessary to give the trees very thorough coverage to the
tops in order to hold the, first brood in'. check.
Connecticut. P. Garman (June 22): The white apple leafhopper is occurring in
New Haven County in about average numbers.
New York. N. Y. State' Coll. Agr. News Letter (June): The black apple leaf-
hopper (Idiocerus provancheri Van D.) is common in Greene County, in the
Hudson River Valley, and in Wayne County, on Lake Erie. The peak of
hatching of the white apple leafhopper occurred between May 25 and 27 in
the Hudson Valley. The first adults were observed on June 2..
Virginia, A. M. Woodside (June 23): Adults of the white apple leafhopper are
moderately abundant in a few orchards in Augusta County.
Indiana. J.,J. Davis (June 25): Apple leafhoppers are showing up in threaten@
ing numbers throughout the State.
Missouri. L. Haseman (June 23): There has been some increase in abundance of
apple leafhoppers; however, there has be.n practically no spotting of apple
APPLE MAGGOT (Rhagoletis pomonella Walsh)
Connecticut. P. Garman (June 22): Emergence of the flies in New Haven County
is much earlier than usual.
New York. N. Y. State Coll.. Agr. News Letter (June): Flies began to emerge at
Poughkeepsie on June 16 and continued to the end of the month.
ORIENTAL FRUIT MOTH (Grapnholitha molesta Busck)
New York. N. Y. State Coll. Agr. News Letter (June): Injury was becoming very
evident in western New York by the end -of 'the month.
Delaware. L. A. Stearns (June 23): First-brood twig injury is light throughout
the State. Parasitization is low in southern Delaware and high in the
northern part of the State. Peach drops show moderate infestation.
Georgia. 0. I. Snap-o (June 14): According to a report, considerable damage to
twigs and fruit of peach is occurring at Griffin, in north-central Georgia.
T. L. Bissell.(June 21): A 3-year-old peach orchard at Experiment is
