The occurrence of grasshopper outbreaks in the Central and Western
States is probably the most serious insect problem that developed during the
month. Grasshoppers were reported in destructive numbers from Michigan and
northwestern Indiana, westward through the northern two-thirds of Illinois
to the Great Plains States, including eastern Colorado, and southward to Ark-
ansas and Oklahoma. The most seriously infested States are Iowa, Nebraska,
Kansas, Oklahoma, and Colorado. The general and widespread occurrence of these
outbreaks prompted Congress to appropriate $250,000 to enable the Bureau to
cooperate with States in a campaign for control. Serious grasshopper trouble
was reported also from Utah and north-central California.

Cutworms were especially abundant throughout the greater part of the
country during the early part of Juno. Many species were involved.

Scattered reports of serious wireworm injury were reported along the
South Atlantic States and into the Gulf Region, with similar reports coming
from the Mississippi Valley and the Groat Basin.

Throughout the New England States and westward to Michigan, rose
chafers did considerable damage to flower gardens and fruit, with occasional
reports of young poultry being killed from eating the beetles.

Rather heavy infestations of wheat by hessian fly were reported from
New York westward to Iowa; however, little commercial damage was reported
over most of the region.

Although the chinch bug was reported as somewhat abundant from Virginia
westward to Nebraska and Oklahoma, little damage was reported in the eastern
part of this region. Some damage was reported from eastern Iowa, Nebraska,Kansas,
and Oklahoma. A small localized outbreak of this insect also occurred in
Northampton County, Va.

The stalk borer was unusually abundant from Indiana westward to Minne-
sota and Kansas, the larvae damaging principally corn and tomatoes.

In the southern Mississippi Valley from Tennessee to the northern half
of Mississippi damage by the sugarcane beetle to corn was reported.

From the Hudson River Valley of.New York southward to Virginia and
West Virginia the rose leaf beetle was probably the most serious pest to flower
gardens and berry crops.


Codling moth entering fruit was reported quite generally over the
Middle Atlantic and East Central States during the latter half of the month
and, although generally reported as having suffered high mortality during
the winter, populations wore increasing rapidly.

Eastern tent caterpillar was reported as quite numerous throughout
the New England and Middle Atlantic States. The peak was apparently reached
last year and this year the outbreak seems to be on the wane.

Apple curculio occurred in outbreak numbers in parts of Ohio, Indiana,
and Missouri.

Plum curculio caused more damage than usual throughout the New England
States, New York, and westward to Indiana. Severe drought in the Fort Valley
section of Georgia delayed emergence of the adults, so that no trouble is
anticipated to peach varieties that ripen before the Elbertas.

Damage by oriental fruit moth is reported from the New England States
southward to Virginia along the Atlantic Seaboard and westward to Illinois
and thence down the Mississippi Valley to the Gulf States. In the East
Central and Gulf States infestations were heavier than usual.

From Massachusetts to Ohio, particularly in the Lake Region, the grape
plume moth did considerable damage.

An outbreak of the false chinch bug occurred from Michigan westward
to Nebraska, the principal damage being done to strawberries, although a number
of other crops were attacked. In California this insect damaged grapes.

Several species of flea beetles were very numerous on truck crops from
New York westward to Nebraska on the north and Missouri on the south, with
similar trouble reported from Utah and Washington.

The Mexican bean beetle was reported as less abundant than usual in
the Ohio Valley and Northeastern States. Late in the month, however, the
insect began to appear in destructive numbers over much of this territory.

Heavy infestations of pea aphid were reported from New York to Wisconsin,
with damage also reported from Kansas, Mississippi, and Utah.

Heavy infestations of cabbage by the imported cabbage worm were reported
from Pennsylvania and Virginia, westward to Missouri. Much early cabbage
was also damaged in this region by the cabbage aphid.

The first record of serious damage to celery by the parsley stalk
weevil in New Jersey was reported this month.

From Wisconsin and Tennessee westward to Nebraska and Kansas strawberry
leaf roller was a major pest of strawberries.

Cankerworms occurred in unusual numbers throughout New England, the
Middle Atlantic, and East Central States, westward to Iowa and Nebraska. Severe


infestations by forest tent caterpillars were occurring over this same terri-
tory, but extending westward only to Minnesota.

The elm leaf beetle was quite prevalent in the New England and Middle
Atlantic States, with unusual damage in the East Central States and localized
outbreaks in Idaho and California.

European elm scale was generally prevalent from New York to Iowa.


The grasshopper outbreak in the Prairie Provinces, which has been wide-
spread, serious, and menacing since 1930, was greatly reduced during 1935 by
weather conditions, natural enemies, and the effects of organized intensive
control campaigns. Indications this spring point to still further reduction.
Hatching in Manitoba was slow and irrogular and no damage has been observed,
so far, except in the southwest, where dry conditions caused some trouble
from grasshoppers. In Saskatchewan hatching began the middle of May, but up
to the middle of June, the infestation in southern areas was very light and
no severe damage had been done. The insects were generally abundant west of
Saskatoon, but damage has been minimized by cool weather, heavy rains, and the
distribution of poisoned bait. In Alberta slight losses to crops were occurring
in drier areas late in June, but theeo were being held in check by the poisoning
campaign. A .moderately widespread outbreak of grasshoppers has developed in
sandy regions of Renfrew and Hastings Counties in eastern Ontario,

Cutworms of several species were reported to be unusually abundant and
causing damage to garden, truck, and field crops in parts of every province
in the Dominion. A resurgence of these insects occurred in many parts of
Canada in 1935. The pale western cutworm is in serious outbreak form in
southern Alberta, causing severe losses to grain crops in some areas. Quite
severe damage was reported also in sections of Saskatchewan. A considerable
outbreak of the red-backed cutworm was reported through much of the northern
and east-central part of the Park Belt in Saskatchowan, with resultant damage
to field and garden crops. It caused local damage in gardens in southern

Wireworns are proving to be the most serious pest of the year in
medium- and light-soil areas of prairie and open-park sections of Saskatchewan.
Losses to wheat seeded in sunmerfallow quite generally ranged from 10 to 50
percent. Infest.tirns have increased markedly in recent years, particularly
in idle fields and in districts affected by drought and soil drifting. In-
fostations are general in nany areas of southern Alborta, with damage slight
to severe. 7ireworns were reported as destructive to grain and other crops
locally in southwestern Ontario.

A major flight of Juno beetles occurred in southern Quebec and much

foliage injury was done to a variety of deciduous trees and shrubs. In sandy
and sandy-loan sections of eastern Ontario white grubs are abundant and
causing damage to timothy sod.

Heavy infestations of the red turnip beetle have occurred on cruciferous
garden plants and weeds in Saskatchewan, west and northwest of Saskatoon, to
the Alberta boundary.

For the first time since 1923, material damage to wheat by the western
chinch bug was reported in the locality of Madison, in western Saskatchewan.
The infestation may be more widespread than indicated by this report.

Crop damage by flea beetles of various species is reported to be
widespread in the Dominion.

Large flights of the beet webworm occurred in the three Prairie Provinces,
and damage to sugar beets by the larvae is threatened in beet-growing areas.

Injury by the cabbage maggot was reported severe in southwestern
Ontario and in the Okanagan Valley, British Columbia.

Orchard insects are generally well under control in the Annapolis
Valley, Nova Scotia, but the rosy apple aphid has appeared in injurious.numbers
in many districts. The green apple bug is also more prevalent than for several
years past.

The strawberry weevil was abundant and injurious to strawberries in
parts of the Annapolis Valley, Nova Scotia, and on Prince Edward Island.

In the Niagara district, Ontario, weather conditions so far have been
unfavorable to the development of the codling moth and oriental fruit moth.
Grape leafhoppers are again present in injurious numbers in this district.

Overwintering tarnished plant bugs have caused serious damage in many
apple orchards of the Vernon district, British Columbia, by destroying the

Trees and shrubs in many parts of the Dominion again suffered foliage
injury from the attacks of tent caterpillars. The eastern tent caterpillar
caused defoliation of neglected orchards in sections of eastern Canada. A
major outbreak of the forest tont caterpillar developed in Ontario over a wide
region north of the Georgian Bay and Loke Superior. Deciduous trees and shrubs
were defoliated, houses and gardens were invaded, and trains wore delayed during
the course of the outbreak, which occasioned much newspaper publicity and con-
siderable public concern. Tont caterpillars were also reported to be unusually
numerous in British Colu-bia.

An extensive outbreak of the jackpine sawfly, apparently Diprion swainei
Middloton, is in progress in the Abitibi Lake region of Ontario. A European
species, D. frutotorum Fab., found attacking pine in the Niagara district in
1934, shows no further spread and is being brought under control in some areas
by imported parasites.



North Carolina. C. H. Brannon (June 25): Grasshoppers are seriously damaging
tobacco in many parts of the State.

Indiana. J. J. Davis (June 22): Grasshoppers (specimens examined are Melan-
oplus mexicanus Sauss.) have been more abundant throughout the State
than for many years. Damage was reported June 14 in St. Joseph and
Elkhart Counties. Since that time reports have been received from
several other northern counties and in Tippecanoe and Vermillion Counties.
In most cases they are breeding in alfalfa fields, completely stripping
the alfalfa and migrating to wheat, soybeans, cowpeas, and corn. At
present most of them are mature.

Illinois. W. P. Flint (June 22): Heavy infestations of grasshoppers are
developing locally throughout the northern three-fourths of the State.
The infested areas are not large, running from 10 to several hundred
acres; in a few cases to a thousand acres or more. The poison bait has
been used very successfully.

Michigan. R. Hutson (June 25): Reports of damage have been received from
Vandalia, Cass County, and Hanover, Jackson County. These points are
below the generally infested area revealed in the survey last fall.

Wisconsin. E. L. Chambers (June 24): For the first time on record, extremely
heavy infestations of grasshoppers are occurring in southern Wisconsin,
but are mostly limited to areas of one or two townships. M. mexicanus
is nearly mature and is cleaning up crops over large areas. Camnula
pellucida Scudd. hoppers have recently hatched. Active control work is
being carried on in Douglas, St. Croix, Dunn, Chippewa, Shawano, Langlade,
Columbia, Rock, Dane, Green, Jefferson, and Portage Counties.

Minnesota. A. G. Ruggles (June 20): Grasshoppers scarce except in two town-
ships in Todd County, in central Minnesota, where they are abundant.

Iowa. C. J. Drake (June 24): The grasshopper situation is very serious in
western and southwestern Iowa. In about 10 counties it now appears that
they will destroy at least half of the grain and most of the alfalfa.
Over 70 carloads of poison bait have been used, and an effort is being
made to obtain 250 more cars. In some of the most heavily infested small
grain and alfalfa fields the population ranges from 50 to 200 grasshoppers
per square yard. The infestation in the southern half of the State is
very spotted. The lesser migratory locust (M. moxicanus) and the two-
lined grasshopper (M. bivittatus Say) are the most abundant species,
many of which are in the adult state. The differential grasshopper
(M. differentialis Thos.) is also very abundant in many localities but
did not hatch as early as the other two species.


Missouri. L. Haseman (June 24): The red-legged grasshopper (M. femur-rubrum
DoG.) is rapidly maturing, while the differential species is still
largely in the nymph stage. In central Missouri there are unbelievable
numbers of the Carolina locust (Dissosteira carolina L.) mingled with
the two harmful species. Practically every section of Missouri is in-
fested with hoppers and, with the shortage of rainfall, they -are already
doing serious damage to cultivated crops in some areas.
Correction.-- The note on Schistocerca americana Drury in Missouri in the
Bulletin, June 1, 1936, page 98, should read D. carolina.

Arkansas. D. Isely (June 24): Grasshoppers are unusually abundant in north-
eastern Arkansas, where a considerable acreage of alfalfa is grown. The
hoppers are now reported as leaving alfalfa and migrating to corn and

North Dakota. F. Gray Butcher (Juno): Grasshoppers have boon reported as
very abundant in 11.counties and moderately abundant in 13 counties.
Some crop injury has occurred in isolated spots, and in such communities
considerable quantities of bait have boon spread. Howover, generally
over the areas of heavy infestation severe drought has so reduced crop
prospects that the farmers are not distributing bait in sufficient
quantities to obtain control.

South Dakota. H. C. Severin (June 20): Grasshoppers are more numerous on
range and pasture land than they have been during the past 25 years.
The ranges and pastures are drying up and the hoppers are moving into
what is left of the cultivated crops. The extreme eastern and the
extreme southern edge still have a chance for a crop, but even in some
of this territory the hoppers are abundant. Some species are already
migrating. Many Pardalophora haldemanii Scudd. are attracted to
electric lights.

Nebraska. M. H. Swenk (June 20): A survey of the adult population and egg
infestation mado in 74 counties in September and October 1935 showed
that many eggs had been laid in practically all of the counties border-
ing on the Missouri River, the southern border of the State, and in
the western part of the State. The eggs overwintered with low mortality
and about May 6 (nearly a fortnight later than normal) they began to
hatch all over eastern Nebrnska. They continudd to hatch out over the
State in large numbers during the greater part of May and before the
end of that month it was very evident that an extensive and serious
outbreak was at hand, rivalling in a number of localities the outbreak
of 1934, if not exceeding it. Up to June 20, serious damage has been
reported in 46 counties. Between these counties the intensity of the
infestation varies greatly, but everywhere serious crop damage is taking
place, not only in gardens but in fields of corn and small grains, and
especially in fields of young alfalfa. The outlook is very threatening
and heavy losses in many counties are probable.


Kansas. H. R. Bryson (Juno 26): Grasshoppers are very abundant generally,
but are causing more damage in the eastern half of the State. In many
alfalfa fields the new shoots for the second crop of hay have been
seriously damaged. The harvest of the small grains has forced the
hoppers to adjoining greener vegetation, usually corn, soybeans, and
alfalfa. Early in June adults of M. moxicanus were found and on June 12,
adults of M. bivittatus were found in the field at Manhattan. These
dates are much earlier than usual for the appearance of the adults of
these species. The grasshoppers in many of the fields near Manhattan
are heavily parasitized by Sarcophaga kellyi Ald.

Oklahoma. F. A. Fent-n (June 23): A very serious outbreak of grasshoppers
has developed in Osage, Pawneo, Noble, Payno, Nowata, Lincoln, and
Pottawatomie Counties. The infestation is spotted but increasing in
19 other counties in western and northwestern Oklahoma. It is quite
likely that the infestations exist in all of the counties of the State,
but the outbreak seems to be more serious in the northeastern part.
A number of species are involved but M. moxicanus is most provolent, with
M. femur-rubrun next. On the night of June 9 a third species was attrac-
ted to lights in a number of cities in the central and northeastern
parts of the State, appearing in Bartlosville at about 9 o'clock in the
evening and at Stillwatcr at.about 11. Literally thousands of then
were blown in by a cold north wind. This species has been tentatively
identified as P. halaemanii. At present the outbreak is steadily
increasing, following the harvest of small grains and cotton, alfalfa,
and Irish potatoes--in fact,all growing crops are being seriously
damaged or destroyed.

Mississippi. C. Lyle (June 25): M. differentialis was attacking 400 acres
of cotton at Sardis on May 28. A prompt application of poisoned bran
quickly controlled the infestation.

Utah. G. F. Knowlton (June 11): Seagulls in great numbers were observed
following the mowing machine at Bcnsrn, oating all of the larger grass-
hoppers as soon as the alfalfa was cut. In Utah County hoppers are very
abundant in the foothills surrounding the farm area at Genola. Adults
of Elliott's locust (Aulocara olliotti Scudd.) and Trimerotropus vincu-
lata Scudd. are nost abundant at this time. Considerable injury to farm
crops is anticipated.

Californiat S. Lockwood (June 12): C. pellucida, devastator Scudd., and
Oedaleonotis enigma Scudd. are very abundant in Tehana, Yuba, Yolo, Sacra-
mento, San Joaquin, Mariposa, Tuolumnc, and Calaveras Counties. Control
campaigns are under way and the damage has been confined largelT to native

EASTERN LUBBER GPASSHOPPER (Romalea micrnptera Bdv.)

Florida. J. R. Watson (June 22): In Clay County there was a heavy infestation
of the lubberly locust. The damage was mostly to summer cover crops, such
as cowpoas, but watormelons, cantaloupes, corn, beans, and okra were con-
siderably damaged.


MORMON CRICKET (Anabrus simplex Hald.)

South Dakota. H. C. Severin (June): Mormon crickets have been sent in from
6 localities in western and central South Dakota. In no instance,
however, have the crickets occurred in sufficient numbers to warrant
control measures.

Utah. C. J. Sorenson (June 19): Mormon crickets have been reported from
Uintah County and 5 miles west of Paradise in Cache County.

CUTWORMS (Noctuida.)

Massachusetts. A. I. Bourne (June 25): On May 18 our attention was called
to very severe damage by cutworms attacking fields of set onions in
Hampshire County. One farm had at least 2 acres so badly damaged that
it was a question of whether the crop would be worth carrying through.

Connecticut. W. E. Britton (June): Cutworms are present in vegetable crops
in the usual numbers and have caused the usual amount of damage through-
out the State.

Indiana. J. J. Dnvis (June 22): The overflow worn (Agrotis ypsilon Rott.)
was abundant in bottom land along the 7abash River, from Clinton south,
and along the Ohio River near Evansville.

Wisconsin. C. L. Fluke (June 20): Lined cornstalk borer (Oligia fractilinea
Grote) has been found infesting young corn in Brown County.

E. L. Chambers (June 24): Severe cutworm outbreaks have been
observed on light, sandy soil throughout the State. Many fields of corn
had to be replanted where control measures were not practical. Severe
damage was reported to tobacco, garden crops, small grain, and corn
during the first 2 weeks of June. About a dozen counties in the central
part of the State wore supplied with poison for control campaigns.

Minnesota. A. G. Ruggles (June 20): Cutworms are moderately abundant.

North Dakota. F. Gray Butcher (June): Pale western cutworns (Porosagrotis
orthogonia Morr.) have been causing considerable damage to cereal crops
in the western portion of the State, especially in Burleigh, Morton,
Stark, and Burke Counties. There have been several reports of almost
complete destruction of large acreages of wheat and other crops. Recent
observations indicate that the larvae are practically full grown and
further extensive injury is not anticipated.

South Dakota. H. C. Severin (June 20): Cutworm damage was more severe this
year than normally. The damage is about over at the present time.

Nebraska. M. H. Swenk (June 20): On May 21 and June 7, respectively, from
Hooker and Morrill Counties came reports of the presence of enormous
numbers of millers of Chorizagrotis auxiliaris Grote. The variegated


cutworm (Lycophotia nargaritosa saucia Ibn.) was defoliating tomato
plants in Lancaster County on June 2, stripping gardens in Webster
County on June 9, and cutting off pea vines in Loup County on June 11.
Cutworm damage was reported from Thurston, Madison, Lancaster, and
Cheyenne Counties from May 21 to June 20. In Thurston and Lancaster
Counties the worms (A. ypsilon) were cutting the corn below the surface
of the ground. The dark-sided cutworm (Euxoa nessoria Harr.) was found
injuring tomato plants in Lancaster County and potatoes in Knox County.

Mississippi. C. Lyle (June 25): Prodonia ornithogalli Guen. was reported
in Learned in cotton and on gladiolus at Ridgcland on May 22.

Utah. G. F. Knowlton (June 6): Cutworms seriously dama-ed bean patches at
Granite and Butlerville in Salt Lnke County.

ARMYWORMP1 (Cirphis unipuncta Haw. et al.)

Iowa. C. J. Drake (June 24): Armyworms are doing a considerable amount of
damage in Fremont County. One 40-acre field of wheat was totally

Nebraska. M. H. Swenk (June): In Lancaster County, during the third week in
June the true arnyworn was danaging wheat heads in a few instances.

Oklahona. C. F. Stiles (June 22): Arnyworns of undetermined species are
reported damag:ing cotton in Canadian County.

A CABBAGE BUTTERFLY (Pontia nonuste L.)

Florida. H. T. Fernald (June S1): The flight this spring appears to have
begun abnut May 10. The butterflies were extremely abundant near New
Smyrna on the 10th and by the 14th had appeared at Daytona Beach (west
side of Halifax River), but had disappeared on the 16th. On the 19th
they appeared on the outer beach on the half-mile-wide key between the
river and the ocean, and wore continuing on the 24th. All were going
north. On June 4 they were very abundant from Indian River City south
to Cocoa, flying in a southerly direction.

A TIGER MOTH (Apantesis sp.)

Mississippi. C. Lyle (June 25): An unusual outbreak of Apantosis sp. has
occurred in Oktibbeha and Clay Counties. The last previous record
was in 1925. The worms were moving out of pastures and destroying
adjacent cotton.

WIREWORMS (Elateridae)

North Carolina. C. H. Brannon (June 10): Wireworns are seriously damaging
corn in Carteret County and peanuts in Chowan County.

South Carolina. W. J. Reid and C. 0. Bare (June 1-8): In the spring of 1936
wireworns (Heteroderes laurentii Guer., and other species) were again


injurious to the early potato crop of the coastal area. An examination
at harvest rf 3,023 tubors taken from four fields in the vicinity of
Charleston vhowed that 41 percent of them had been injured by wireworms.

F. F. Bondy and C. F. Rainwater (June): Wireworms (Melanotus
sp. and Aeolus sp.) are noro abundant than usual on cotton at Florence,
and have reduced the stand in some places, especially where corn was

Georgia. 0. I. Snapp (June 19): J. R. Thomson reports that adults of Mono-
crcpidius vespertinus Fab. appear to be more abundant than usual in peach
orchards at Fort Valley.

Indiana. P. Luginbill (June 10): Several fields of corn near Delphi injured
by wireworns, probably Drasterius sp.

Kentucky. W. A. Price (Juno 25): Wireworns have been destructive to corn and
tobacco plants at La Grange, Greenville, and Springfield.

Wisconsin. E. L. Chambers (Juno 24): Considerable danago to tobacco, corn,
ncd gardon crops is being reported from various points in the State.

Missouri. L. Hasenan (Juno 24): 77e have not had the usual June complaints
against wiroworms, but a grcat many farners are having difficulty with
then in patches, particularly in lowlands.

Mississippi. C. Lyle (June 25): Several fields of cotton and corn were being
damn cI c at MIrgantown on June 15 by larvae of the sand wireworm (Horis-
tonotus uhlerii Horn). The danare was principally in spots scattered
erer the fields.

Idaho. R. W. Haoeele (June 15): W'ireworms arc snoewhat nore d-a.aging than
usual, feedin- heavily during May on early planted crops such as wheat,
corn, and onions. Later plantings, especially of corn were also injured,
as the wireworn feeding extended well into June.

Utah. G. F. Knowlton (June 6): Wireworns are damaging young sugar beets
and tomatoes in a few fields at Lewiston.

WHITE GRUBS (Phyllopha a spp.)

Pennsylvania. K. Hower (May 29): A beetle has boon appeavrin around Midville
in great swarms. (Identified by E. A. Chapin as P. tristis Fab.)

Georgia. 0. I. Snapp (June 16): Not so abundant as usual at this time of the
year at Fort Valley. A number have been taken from soil under the
spread of peach trees, the foliage of which they attacked during the

J. M. Robinson (June 2): The brown June bug (P. nicans Knoch) has
been attacking pecan and white oak trees in groves that have not been


cultivated, and in groves on the uplands near West Point. The beetles
were very aetive the last week of April and the first week of May.

Indiana. J. J. Davis (June 22): 'hite grubs were reported to bo heavily
infeoting lawns at Culver on Juno 17.

Wisconsin. E. L. Charbers (Juno 24): Unusually heavy flights of P. tristis
were observed throughout the southern part of the State during the
latter part of May and the first week of June. Many rcports are being
received fron the counties of the central part of the State, stating
that serious daname is beingc done to strawberry, potatoes, and gardons.

Iowa. C. J. Drake (June 21): Danage by white grubs, brood A, is beginning
to show up in cornfields. The infestation is very widespread and ex-
tends beyond the eastern half of the State.

JAPANE'SE BEETLE (Popillia japonica Newn.)

Delaware. L. A. Stearns (June 15): First adults of the Japanese beetle were
observed at Newark today.

Pennsylvania. H. E. Hod:kiss (June 23): Adults were boeinnin7 to appear
during the week of June 15 in the Philadelphia area,

7ashinjton, D. C., and Maryland. 3. A. Porter (Juno 30): Adults of the
Japanese beetle are being reported from the District of Columbia and
nearby Maryland.

A SCARABAEID (Ochrosidia innaculata Oliv.)

Kentucky. W. A. Price (June 25): Pupation began the last week in May and
continued through the second we3ck in June. The first adult was taken on
June 7 at a light. A heavy flight of this insect is expected soon in
the vicinity of Lexington.

ROSE CHAFER (Macrodactylus subspinosus Fab.)

Maine. H. B. Poirson (June 21): Heavy outbreaks of rose chafors reported
from Augusta, Portland, and Wayne, where the beetles wore attacking
fruit and foliage of apple.

Vernont. H. L. Bailey (June 18): Rose chafers very abundant generally on
June 15. Serious problen at Milton, where many young pheasants were
killed by eatirn the beetles.

Masachusetts. A. I. Bourne (June 25): Rose chafer appeared during the week
of Juno 5 to 7, and fron all indications it is about as abundant as

Connecticut. E. P, Felt (Juno 24): The rose chafer has been sonowhat
abundant in the Stamford area.


Now York. .R. E. Horsey (June 10): A few rose chafers on peony and roso flowers
at Rochester. Nn noticeable ramage.

jurious to c-ak trees at ExpTriment. The nites are working on the upper
surfaces of the loaves.,

Ohio. E. e. iendonhall (June 10): The rod sp.ider is very abundant. on arbor-
vitae st-ck in the nursery at Xenia, causing some damrue.

Kentuccky . A. Price (June 25): Red spiders are cmmnnn and destructive over
the State generally.

Tennessoe. G. I.. 3Bntley (June 20): Red- spider is present generally over the
State, attacking: a larIe variety of ornamentals. 'Jc have had several
conplaints of its attacking boxwood.

Missouri and Kansa,-. H. Baker (June 24): The cor-unn red spider, which has
boon a serious epst in aplple orchards in this section the last 2 years,
i:. difficult to find in orchards.

Mississippi. C. Lylo (June 25): On account of the severe drmou7ht throughout
the northern and central parts of Mississippi this nonth, rod spider
injury has been sov-re. The southern part of the State, with more rain-
fall, has apparently suifffred less.

Utah. G. F. Knowlton (June 6): Rod spiders ard damacing raspberries, straw-
berries, and dowberries at Pleasant Grove and Linden.



HESSIAL~ FLY (Phytophaa destructor Say)

Now York. N. Y. State Coll. A-r. News Letter (June 15): Hessian fly has done
considerable damnag to the wheat in some sections of Genesee County.
Three fields that have been observed are infested practically 100 percent.

Ohio. T. H. Parks (June 25): The wheat-insoct survey has started in the
southern and central counties, where six counties have been visited. The
avorae percontawe of stems infested in four southwestern counties is
20.5 percent and for the two central counties is 12.4 porcent. No
loding of straws has occurred and practically no co:.iercial dapmafc.

Indiana. C. M. Packard (June 16): Severe spring infestation and injury to
many wheat fields seen in Posey and Gibson Counties. Much broken-ovcr
straw. Fly now mostly in flaxsced stage.

Iowa. C. J. Drake (June 24): Very liiht infestations throughout southern
Iowa but no con-ercial dana.,e.

Missouri. L. Hasenan (June 24): Owin.- to the unusual weather, the spring
brood did comparatively little damag:e in the State, and many farmers
have harvested fair yields in fields that locked like a cor-ilete loss
last fall. The spring brood has been about as abuncdant in the northern
third of the State as in the southern two-thirds, where it was so
throatoning last fall. There is sufficie:nt fly in wheat stubble over
nost of the State to scriously threaten early seedod wheat this fall.
Fortunately, parasitization of flaxsoeds in so:e areas is quite high.

WHEAT STEM MAGGOT (Meron-yza aenricana Fitch)

Iowa. H. E. Jaques (June 22): The wheat sto: na:got is to be found in many
rye and wheat fields.

Kansas. H. R. Bryson (June 23): Wheat stem ua~got is more abundant than
usual this year.

A BILLBUG (Calendra sp.)

Kansas. H. R. Bryson (June 26): The wheat billbug caused a considerable
amount of wheat to go down in some fields west of McPherson. This is
of considerable interest because the insect is also found in some of the
adjoining grasses, especially Agropyron smithii.


CHINCH BUG (Blissus leucopterus Say)

Virginia. H. 7V. 'Jalker (June 24): Chinch bugs were reported by the county


.-cnt as seriously injuring corn in Torthar.Tton County.

North Carolina. C. H. Brannon (June 27): Infe'station of chinch bugs is
generally heavy over the eastern and Piedmont sections of the State,
for the first time in over a decade.

Ohio. T. H. Parks (June 11): Very few chinch bugs are present in the wheat
fields and we anticipate no damage to corn. Young bugs hatched on June

Indiana. D. W. La Hue (June 18): A survey of Tippecanoe County shows chinch
bugs scarce in most wheat fields. Old bugs are disappearing. All
stages of first brood, from eggs to fourth-instar nymphs, are now

Illinois. W. P. Flint' (June 22): The weather during June has been almost
ideal for chinch bug development. There will be no general outbreak
in the State, but many scat-tred infestations occur throughout the
central and, particularly, the west- and southwest-ccntral parts of
Illinois. Fields that wero evon lightly infested early in the season
are producing many more bugs than in an avora-e year.

Wisconsin. E. L. Chambers (Juno 24): As indicated by the survey made late
last fall, there will apparently be little damage this summcr, although
the dry scanon is very favorable for chinch bugs. Limited serious
outbreaks have boon observed near Plum City, in Piorce County.

Iowa. C. J. Drake (June 24): Chinch bug damage is beginning to show up in
about 10 southern counties. In most cases the bugs will not leave the
small-grain fields until after the grain is cut. The infestation is
very spotted, but a light populntion may be found in many southern and
southeastern countics.

Missouri. L. Hasoman (Juno 24): From central Missouri south the annual
migration of chinch bugs from small grain to corn is now pretty well
over, but in the northern counties migration is still in full swing.
The heavy movement of bugs during the month has boon particularly
noticeable from Kansas City south to Joplin and in a northeasterly
direction across to St. Louis and Hannibal, with some heavy epidemics
in north-contral Missouri. On some farms the bugs have been fully as
abundant as in 1934, but heavy infestations have boon more scattering.

Nebraska. M. H. Swonk (June 20): Chinch bugs appearod in injurious numbers
in the small-grain fields of Richardson County in extreme southeastern
Nebraska early in June, and 2,000 gallons of creosote were used in three
townships in that county between June 4 and June 18. No serious infes-
tations have been reported outside of Richardson County.

Kansas. H. R. 3ryson (June 23): The chinch bug infestation in the.vicinity'
of Manhattan is much lighter than it has boon since 1934. In south-
eastern Kansas the bugs did considerable injury to the small grain on


the uplands earlier in the season. Enough bugs are present to warrant
the construction of barriers.

Arkansas. D. Isely (June 24): Scattered local outbreaks of chinch bugs have
been reported from the northern part of the State.

Oklahoma. F. A. Fenton (Juno 23): Chinch bugs have appeared in several of
the counties in the State and are now migrating from small grains to
corn. Although not widespread, the infestAtion is more serious than
it has been since 1934.

C. F. Stiles (June 20): There is a section consisting of about
five counties in oast-contral Oklahoma that is very heavily infested.
Rainfall there has been only about half the normal amount. Large popula-
tions have been built up and the bugs are moving from small-grain to row
crops. About a half carload of oil, that we have had in reserve, is
being used to construct barriers; however, this will only partly meet
the demand.

HAIRY CHINCH 3UG (Blissus hirtus M1ontd.)

Massachusetts. E. P. Felt (June 24): The hairy chinch bug was recorded as
occurring in large numbers in a lawn at Lenox.

STALK BORER (Papaipema nebris nitela Guen.)

Indiana. J. J. Davis (June 22): The stalk borer was reported to be attacking
corn at La Fayette and tomato at La Porte on June 16. In both places
the borers were quite small, i.e., not over inch long.

Minnesota. A. G. Ruggles (June 20): The stalk borer is moderately abundant
in Minnesota.

Iowa. H. E. Jaques (June 22): The common stalk borer seems to be more than
usually abundant throughout the State.

Missouri. L. Hasoman (June 24): During the month we have had numerous
complaints of stalk borers from almost every section of the State. At
this time they nre about half grown.

N ebraska. M. H. Swenk (June 17): A Thurston County corrospondent reported the
common stalk borer working on tomato stems.

Kansas. H. R. Bryson (Juno 11): The common stalk borer is reported injuring
tomatoes at Brookville and White City, corn at Leavenworth and Clyde, and
potatoes at Mulberry.

CORN EAR WORM (Heliothis obsoleta Fab.)

New Jersey. T. J. Headlee (June 24): Small numbers of larvae are now present
in the field in the southern counties of the State. The infestations are


not so severe as at this time last year. ,Observations were made in
several sweet-corn fields in Monmouth and Middlesex Counties on June 22,
but no larvae vere seen.

Alabama. J. M. Robinson (June 24): Corn ear worms are abundant in corn and
are also attacking tomatoes in central and southern Alabama.

Mississippi. C. Lyle (June 25): Nearly all Plant Board inspectors have re-
ported considerable damage to tomatoes.

Kansas. H. R. Bryson (June 23): Corn ear worm is causing considerable injury
to the curl of field corn and the young ears of early sweet corn.

California. A, E. Michelbacher (June 20): Eggs were found in central Calif-
ornia about June 1 on tomato plants. Eggs can now be found in most tomato
fields and in places a careful examination will reveal a few small larvae.
An examination of the tomato fields about Visalia showed that the amount
of fruit infested ranged from less than 1 to 7 percent. On June 4 near
Brentwood one corn field was examined and about 10 percent of the ears
were found to be infested. In other fields in the same area not more
than 1 percent of the ears were infested. Some of the larvae were nearly

WEBWORMS (Crambus sp.)

Indiana. J. J. Davis (June 22): Webworms were reported to be damaging corn
the first half of June in several localities in the northwestern quarter
of the State.

Missouri. L. Haseman (June 24): Sod webworms were very troublesome last
month, but they apparently ran their cycle by the early part of June.

SUGARCANE BEETLE (Euetheola rugiceps Lec.)

North Carolina. C. H. Brannon (June 25): The rough-headed corn stalk beetle
is damaging corn over a wide area in the State.

Tennessee. G. M. Bentley (June 20): Specimens of the rough-headed cornstalk
beetle were sent in from many parts of the State together with specimens
of injured corn plants. In some years this insect proves to be a very
serious pest, and reports received indicate that the injury this year
will be serious.

Kentucky. W. A. Price (June 25): Rough-headed cornstalk beetles ruined a
10-acre field of corn at Mayfield.

Alabama. J. M. Robinson (June 24): At Malone the rough-headed cornstalk
borer is seriously attacking several acres of corn. This insect is also
active in Cullman County, particularly at Hanceville.

Mississippi. C. Lyle (June 25): The rough-headed cornstalk beetle has
caused unusually heavy damage this spring in the northern half of Missi-


SOUTHERN CORN LEAF BEETLE (Myochrous denticollis Say)

Nebraska. M. H. Swenk (May 26): Specimens of the southern corn leaf beetle
were sent in on May 26 from Washington County, where they were reocrted
to be doing considerable damage to young corn plants just coming through
the ground. This is the first record for Nebraska of this past's
doazaging corn.

IMBRICATED SNOUT BEETLE (Epicaerus imbricatus .Say)

Wisconsin. C. L. Fluke (June 20): Found largo numbers of imbricated snout
beetles injuring corn at Monroe on May 23.

FIELD CRICKET (Gryllus assinilis Fab.)

South Dakota. H. C. Severin (June 21): The block field cricket has done
considerable damage to gmrninating corn in central and western South
Dakota. Replanting of some entire fields was n-cessary.



Oklahoma. C. F. Stiles (June 22): I find that one of the false wireworms
has been doing enormous damao to the rowed sorghums in Boavor County.
It seems that the adults at this time are causing most of the dacmage.


ALALFA ZEEVIL (Hypera postica Gyll.)

Nebraska. M. H. Swenk (June 1S): Specimens collected in western Nebraska
have been identified by A. G. Boving and L. L. Buchanan.

Idaho. R. W. Haegelo (June 15): The alfalfa weevil is present in southwestern
Idaho. Damago to first crop is moderate and scattered. The parasite
Bathyplectes curculionis Thos. is very abundant. At Parma on June 11,
just before cutting of the first crop, 100 sweeps of a 12-inch net
yielded 297 weovil larvae and 521 adults of the parasite.

F. H. Shirck (June 1): Alfalfa weevil is more abundant in the Parma
district than in any previous season since 1930. No severe injury appears
to have been caused to the first cutting of alfalfa.

Utah. C. J. Sorenson (June 10): Some damage apparent by alfalfa weevil, which
is moderately abundant in Millard County.

California. A.E. Michelbacher (June 20): The larval population of the alfalfa
weevil has slightly increased during the ionth. In sovoral fields as ma=y
as 200 can be collected to 100 sweeps of an insect net. The increase is
probably due to the fact that some of the early brood have matured. Para-
sitization by Bathyplectesis falling off rather rapidly. The decrease is
most marked in the San Joaquin Valley.



ROSE LEAF BEETLE (Nodonota puncticollis Say)

New York. N. Y. State Coll. Agr. News Letter (June): Rose leaf beetles are
damaging fruit in the Hudson River Valley.

Maryland and Virginia. W. H. White (June 3): During the latter part of May
and the early part of June many reports have been received regarding the
abundance of the rose leaf beetle to rose, peonies, azalea, raspberry,
and strawberry in parts of Maryland and Virginia adjacent to the District
of Columbia.

West Virginia. L. M. Peairs (June 18): This chrysonelid has done a lot of
damage to apples and other fruits. We have it from the Eastern Panhandle,
where it is generally distributed, and from as far west as Lewis County.
(Det. by H. S. Barber as Nodonota, probably puncticollis.)
A CHRYSOMELID (Gastroidea aenca Molsh.)

Virginia. W. J. Schoono (Juno 25): This loaf beetle was very abundant
during the last week of May and the first week of Juno. It ate holes in
the sides of many apples and was very abundant in roses and other flowers.
It has accounted for about as much injury to fruit as the worst of our
early season posts.

FLAT-HEADED APPLE TREE BORER (Chrysobothris femorata Oliv.)

Georgia. T. L. Bissell (June 25): Borers have done very little injury to
pecan trees at Milner and Macon the past year, in comparison to injury
in the same orchards in previous years.

Missouri. L. Hasoman (Juno 24): The adult was on wing throughout June but
no activity of the larvae has been noted on trees visited by the beetle.

Nebraska. M. H. Swonk (May-Juno): Reports of injury to fruit and shade trees
were received during the last 2 weeooks of May, and the first 2 weeks of
June from DouLglas, Washington, Dodge, Seward, Buffalo, and Hayes Counties.

A FLOWER THRIPS (Frankliniella occidentalis Perg.)

California. S. Lockwood (June 12): The blossom thrips has been responsible
for considerable scarring to stone fruit in Contra Costa, Solano, Placer,
and Tulare Counties.

PLANT BUGS (Lygus spp.)

Michigan. R. Hutson (June 25): The tarnished plant bug (L. pratensis L.)
has been reported as very abundant on poaches from Albion, Howell, Grand
Rapids, Fonnville, Sodus, and Hartford.

Connecticut. P. Garman (June 19): L. caryae Knight and other species are
present in some orchards but not so abundant as they were last year.



CODLING MOTH (Carpacapsa pomonella L.)

Now York. D. W. Hamilton (June 22): At Poughkeepsie peak moth captures in
light and bait traps occurred on the nights of June 1 and 2. Since then
activity seems to have gradually tapered off. First-brood larvae began
entering the: fruit on June 6. Peak entrances occurred from June 10 to
14. At present the infestation appears to be about normal. Low ten-
peratures and rains have prevented extensive adult activity on many

New Jersey. T. J. Headlee (June 24): Emergence this year began 10 days
earlier than last year. The prospects now are for a full second brood
and a partial third in southern New Jersey.

Delaware. L. A. Stearns (June 23): First-brood injury at this date is lighter
than at any time since 1929. First-hatched larvae are already nature.

Pennsylvania. H. E. Hodgkiss (June 23): First-brood larvae were first seen
going into apples in Cumberland and Franklin Counties on June 18 and 19.
The entries had been made since June 11.

Maryland. E. N. Cory (June 25): Emergence in Washington County was consider-
ably delayed on account of cool weather.

Ohio. T. H. Parks (June): Moths have been caught in the bait pans at
Columbus almost daily from May 16 to June 21. Heaviest flight occurred
between May 30 and'June 54 First entrances were noticed on June 9, the
same date on which entrances were noticed in Ottawa County.

Indiana. J. J. Davis (June 22): Codling noth is noticeably increasing in the
southern half of the State, Unfavorable conditions during the season of
1935 and the past two winters reduced the insect to almost negligible
numbers. However, conditions for the first 1936 brood have been favorable
and the population has built up to threatening numbers. For record we
are summarizing life-history records, those at Bicknoll, ElberfOld and
Vincennes, by L. F. Steiner, and those at Orleans by G. E. Marshall.
First pupae were found at Elberfeld on April 10; at Bicknell on April 13.
First noth at Elberfeld on April 30; in traps at 'Bicknell on May 4;
at Orleans in out-of-door emergence cage on May 4, in packing shed on
May 5, and in bait trap on May 7 (last year, first noth bait trap on
May 8). First eggs laid in insectary at Vinconnes, under normal out-
of-door conditions on May 7, began hatching on May 14. At Orleans the
first eggs hatched on May 21. First larval entries at Vincennes were
observed on May 19. First larvae loft apple to pupato at Orleans on June
8 and at Bicknell on June 10.

L. F. Steiner (June 11); Practically no moth activity either at
Vincennes or Bicknell for the past 10 days. Mature larvae began leaving
apples at Bicknoll on June.10.- In most orchards where the codling moth

-176- :

produced the least injury in many years last season it is now back to
its normal abundance. The light-to-moderate crop at Elberfeld is
nearly 40 percent damaged. '(June 22)'r"bDamage by first-brood larvae
is as severe at Vincennes as has been. observed for several years, des-
pite a subnormal carryover from 1935".

Illinois. W. P. Flint (June 22): In, southern Illinois the codling moth has
developed so rapidly that it is now nearly as abundant as it was in the
spring of 1934, although the last-winter carry-over was the lowest in
6 years.

Kentucky. W. A. Price (June 25): In-,some orchards, particularly in the
Henderson district, there is a heavy infestation. A normal carry-over
with a reduced crop this yeqr has resulted in a'larger number of worms
entering individual fruits. Some apples have as many as five worm

L. F. Stoiner (June 11): Mature larvae began leaving apples at
Henderson about June 2. Now they are:leaving in large numbers. The
injury is almost 40 percent, and in some..orchards it appears even worse.

Michigan. R. Hutson (June 20): A full flight of moths occurred on June 5
at Hartford, Milburg, and Saint Joseph. (June 25): Larvae are fairly
abundant and are from I to 3/8,inch.long at Mason, Albion, Vandalia,
and Buchanan.

Tennessee. G. M. Bentley (June 20): Where timely sprays have not been made,
the codling moth is doing damage generally over the State, the injury
being in small home orchards.

Georgia. C. H. Alden (June 22): At Cornelia first-brood moths have been emerging
in large numbers, starting June 19.

Missouri. L. Haseman (June 24): Moths of the second brood began emerging in
extreme southeastern Missouri on June 14 and 15, and' in central and
southwestern Missouri by June 19 and. 20.. In the northern part of the
State they have been a few days later than in central Missouri.

H. Baker (June 24): First-brood .damage was generally light at
Saint Joseph, except in some poorly sprayod orchards. First-brood moths
were taken in bait traps beginning June 18, or about a week earlier
than expected.

Nebraska. M. H. Swenk (June): Larval mortality at Lincoln was about 91
percent last winter. Spring-brood moths began emerging about May 11 and
first-brood eggs were being deposited by May 30. All first-brood larvae
had pupated by June 13. The first complaint of damage was received
from Buffalo County during the first week in June.

Kansas. H. R. Bryson (June 24): Second-brood adults are beginning to emerge.
Population is building up from a low carry-over of last winter. A third


brood will be present this year, whereas only two broods were present
last year.

Utah. C. J. Sorenson (June 19): The codling moth is very abundant in Cache
and Utah Counties .

EASTERN TENT CATERPILLAR (Malacosoma americana Fab.)

Maine. H. B. Peirson (June): Throughout Maine the insect is much less abun-
dant than in 1935.

Massachusetts. A. I. Bourne (June 25)i Tent caterpillars began to hatch about
the 9th or 10th of April and have been unusually abundant, fully as
abundant as they wore last year, particularly in the eastern part of the

Connecticut. W. E. Britton (June 22): The eastern tent caterpillar was just
about as prevalent as last year in certain localities in southern Connec-
ticut, but much less so in northern Connecticut. Many caterpillars died
from "wilt" and many were parasitized.

New York. R. D. Glasgow (June.17): The eastern tent caterpillar, which has
apparently reached its maximum abundance this year in many parts of
eastern New York, has been a wilt discase in parts of Albany
County and elsewhere.

R. E. Horsey (Juno): Eastern tent caterpillar was abundant in a
territory extending to 10 miles south of Rochester on May 31,

Pennsylvania. R. M. Baker (June 9): First adults appeared in Clark's Valley
on June 6. The infestation was spotted this year, indicating a decline
in population in some sections of the State.

FRUIT TREE LEAF ROLLER (Cacoecia argyrospila Walk.)

Ohio. T. H. Parks (June): Apple leaf roller is more abundant than usual in
all parts of Ohio. In some orchards it has disfigured a high percentage
of the fruits.

LEAF CRUMPLER (Mineola indigenella Zell.)

Alabama. J. M. Robinson (June 2): The larva of the leaf crumplcr was re-
ported attacking apple trees at Uriah on May 9. Adults emerged on May
20. They were reported as being serious pests to apple in that area.

EYE-SPOTTED BUDMOTH (Spilonota ocellana Schiff,)

Massachusetts. A. I. Bourne (June 25): We found budmoth to be rather more
abundant than usual on the fruit crops.

New York, N. Y. State Coll. Agr. News Letter (June): Quite an infestation
of budmoth developed in a few localities in western New York.



Massachusetts. A. I. Bourne (June 25): We noted that apple aphids in
orchards at Amherst were hatching as early as March 28, owing to warm

Connecticut. P. Garman (June 19): Rosy apple aphid (Anuraphis roseus Bak.)
is very abundant in some orchards. The outbreak, however, is by no
means general. A decided increase took place from June 1-15, but migration
is now well under way.

New York. N. Y. State College Agr. News Letter (June 29): The rosy aphid
has built up to serious proportions .in many orchards in Niagara County
and is also causing concern to orchardists in Monroe and Wayne Counties.

New Jersey. T. J. Headlee (June 24): Infestation of the green apple aphids
(Aphis pomi DeG.) began showing up in some orchards by June 10. The in-
festation in some orchards, where growth of foliage was active, has
reached a point where sprays are advisable.

Pennsylvania. H. E. Hodgkiss (June 23): The rosy apple aphid has caused
fruit injury in many orchards throughout the State, but no commercial
damage has been done. The green apple aphid is reported to have started
on water sprouts during the week of June 15.

APPLE MAGGOT (Rhagoletis pomonella Walsh)

New York. N. Y. State Coll. Agr. News Letter (June 22): Flies began
emerging from trap areas in the vicinity of Poughkeepsie on June 17.
The first emergence for the Hudson Valley is at least 4 days earlier
this year than it was in 1935.

APPLE CURCULIO (Tachypterellus quadrigibbus Say)

Vermont. H. L. Bailey (June 18): Adults of apple curculio were found on
apple at Montpelier on June 8.

Ohio. T. H. Parks (June): Specimens of apple curculio with injured fruit
were received from Hamilton County with the statement that the insect
is injurious in several orchards.

Indiana. J. J. Davis (June 22): Apple curculio has been noticeably more
abundant throughout the State than for many years.

Missouri. L. Haseman (June 24): During the first week in June a very severe
epidemic of apple curculios showed up in northeastern Missouri, extending
from Elsberry north through Clarksville and Louisiana to Hannibal. Less
noticeable outbreaks were also observed at Macon and Chillicothe. There
was practically no evidence of the insect at Columbia and in the other im-
portant orchard centers of the State. Near timber, fruits on many trees
were damaged practically 100 percent, with from 1 to 100 punctures to the
apple. The attack largely subsided by the 15th of the month.


A SCARABAEID (Pachystethus marginata Fab.)

North Carolina. C. H. Brannon (June 25): Seriously damaging apple leaves
and fruit in an orchard in western North Carolina,

EUROPEAN RED MITE (Paratetranychus pilosus C. & F.)

Massachusetts. A. I. Bourne (June 25): European red mite has been very abun-
dant in many orchards and seems to be giving more trouble this year than

Connecticut. P. Garman (June 19): European red mite is present in some loca-
tions and is abundant in a few orchards.


PLUM CURCULIO (Conotrachelus nenuphar Hbst.)

Vermont. H. L. Bailey (June 18): Adults of the plum curculio were found on
apples at Montpelier on June 8.

Connecticut. P. Garman (June 19): Plum curculio is from moderately abundant
to severe in some orchards in New Haven County.

Rhode Island. A. E. Stone (June 22): Plum curculio apparently more abundant
than during the past two seasons.

New York. N. Y. State Coll. Agr. News Letter (June): The plum curculio is
causing more damage than usual in some orchards in western New York.

Georgia. 0. I. Snapp (May 28): The first new beetles of the season emerged
today from soil in the laboratory at Fort Valley. May 28 was also the
emergence date of the first new beetle in the laboratory last year.
(June 12): New beetles are now emerging in numbers from the soil in
commercial peach orchards at Fort Valley. Recent thundershowers have
facilited their escape from the soil after a long drought. We took 96
new beetles from 24 trees in a commercial orchard today where there
were practically no beetles last week. (June 18): The first eggs of
the second generation were recorded yesterday. Eggs were obtained from
2 of 156 individual pairs examined. These pairs emerged on June 2 in the
laboratory, somewhat earlier than in the field. (June 19): The infestation
at Fort Valley continues to be less than that of an average year. No
trouble from a second brood is anticipated in varieties ripening before
the Elberta,

C. H. Alden (June 22): The peak of first-brood emergence occurred
in the Thomaston section on June 9, The first curculio was caught on
June 16 at Cornelia; peak emergence has not occurred there yet.

Tennessee. G. M. Bentley (June 20): The two-month drought and the plum cur-
culio attack on unsprayed orchards have caused a heavy drop of plums and
peaches. This, however, is true only of the uncared-for trees.

-180- *

Indiana. J. J. Davis (June 22): Plum curculio is more abundant than usual
throughout the State. Injury was observed only a few days after petal
fall in southern Indiana, during the week of May 3.

Minnesota. A. G. Rugglos (June 20): Plum curculio has been moderately


California. H. C. Donohoe (June 1): A grower in the vicinity of Fresno reports
that the western twelve-spotted cucumber beetle is seriously damaging ripe
early peaches. It attacked home vegetables and ornamental garden plants
more severely than in a normal year.

SHOT-HOLE BORER (Scolytus rugalosus Ratz.)

Georgia. T. L. Bissell (June 9): Infestation of peach trees by bark beetles
at Griffin is very noticeable in some orchards. The beetles bore into
the base of leaf clusters and of fruit pedicels, killing the leaves.
Injury is traceable to the improper disposal of peach prunings. A report
of plum, similarly infested comes from Columbus.

Alabama. J. M. Robinson (Juno 2): In Double Springs peach trees were dying
from winter injury and shot-hole borers were attacking the dying trees.

A CURCULIONID (Sitona prominens Csy.)

Georgia. 0. I. Snapp (June 19): These beetles are more abundant at Fort Valley
than usual. They havo the habit of congregating on peaches in the de-
pression around the stem.

ORIENTAL FRUIT MOTH (Grapholitha molosta Busck)

Connecticut. P. Garman (June 19): The first generation of the oriental fruit
moth is extremely scarce.

New York. N. Y. State Coll. Agr. News Letter (June): Twig injury has been
observed in orchards in Monroo and Orleans Counties.

Delaware. L. A. Stearns (June 23): Parasitization of first-brood larvae is
below normal. The first second-brood eggs were deposited on June 17, and
the first second-brood larvae hatched on Juno 21.

Now Jersey. G. J. Haeussler (May 18): First-brood larvae began entering peach
twigs in the vicinity of Moorestown about May 14, approximately 2 weeks
earlier than last season. In several orchards in Burlington County infested
twigs are already fairly abundant and the first-brood infestation is con-
siderably more severe than that of 1935. (May 26): The first-brood
infestation is very light at Glassboro and Richwood, in Gloucester Coim4y,
and at Lawrenceville and Glennore, in Mercer County.

Maryland. H. W. Allen (May 16): Infestation of peach twigs by first-brood
larvae was observed to be from light to moderate in the vicinity of

Virginia. H. W. Allen (May 12-14): Infestation of peach twigs by first-
brood larvae was observed to be heavy in the vicinity of Lovingston;
moderate at Bonsac, Cloverdale, Winchester, and Washington; and light
at Crozet, Waynesboro, Staunton, and Timberville.

Georgia. 0. I. Snapp (June 19): The infestation is lighter than usual. It
is confined to home orchards in and near Fort Valley.

T. L. Bissell (June 24): A small number of peach shoots were found
infested with larvae today at Rover, in Spalding County.

Ohio. T. H. Parks (June): Peach trees were very slow to recover from the
severe winter injury and have shown more than the usual degree of in-
festation. There are no peaches, except a light crop in the lake-shore

Indiana. J. J. Davis (June 22): Injury is rather conspicuous throughout the

and Spanish Fork.

Wyoming. M. Greenwald (June 22): Millers were very numerous at Powell up to
June 15, after which date they dropped off gradually in numbers. Worms
are now numerous enough in some sugar beet fields to warrant spraying.


BEAN APHID (Aphis rumicis L.)

California. S. Lockwood (June 12): The bean aphid is more prevalent than
usual in the Sacranento River Delta. They were numerous enough -to shorten
the crop of horse beans, and they migrated into sugar beets after the
horse beans became dry. It is doubtful whether 800 acres of sugar'beets
in this region will withstand the attack made by these aphids.

in the southeastern part of the State, being observed in McCurtain and
Choctaw Counties, The infestation is spotted and light and no damage is
being done.

Texas. F. L. Thomas (June 12): First-generation weevils now may be found in
southern and central Texas and are already causing considerable injury.
In one field of Victoria County, 75 percent of the squares were punctured,
and in Matagorda County, 20 percent. Although little cotton is grown in
the vicinity of Dinnit County, in one field examined 81 percent of the
squares were found to be infested. (June 19): Boll weevils have been


found in Kaufman and Smith Counties in northern and northeastern Texas.
They occurred at the rate of 50 per acre in Kaufman County. In 5
counties of southeastern Texas the infestation was 16 percent, with a
maximum of 38 percent in Matagorda County. In 8 counties of southern
Texas the average infestation on 11 farms was 15 percent, with a maxi-
mum of 40 percent in Jackson County. (June 26): The average infes-
tation was 24 percent on 10 farms in the southern part and 27 percent
on 7 farms in southeastern part of the State. This is an increase of
9 and 11 percent, respectively, over the infestation reported the
previous week.

June 17.

APHIDS (Aphiidae)

North Carolina. C. H. Brannon (June 26): Cotton is heavily infested with
aphids over a wide area of the State.

Mississippi. C. Lyle (June 25): During the latter part of May and the early
wooks of June, many fields of cotton in the southern part of the State
were rather heavily infested with the cotton aphid (Aphis &ossypii
Glov.). With warm weather and an abundance of predators, the aphids
have practically disappeared.

F. A. Fenton (June 23): Unusually prevalent on cotton at
chopping time throughout most of the State and in some cases killed the
plants, necessitating replanting. Most of the plants, however, had fully
recovered by the end of the month.

COTTON FLEA HOPPER (Psallus seriatus Rout.

Mississippi. C. Lyle (June 25): Infestation in the vicinity of State College
is very light. The insect is present on stveral farms in the Delta and
central part of the State.

Oklahoma. F. A. Fenton (June 23): Reports have been received of the presence
of the cotton flea hopper. Injury at present seems to be centered in
the southeastern part of the State in the counties along the Red River,
especially in Bryan County.

Texas. F. L. Thomas (Juno 5): The average number of flea hoppers hatching
from 100 croton woods in May was more than double the number hatching
during any previous May for the past 10 years. (June 12): Flea



hoppers are increasing in southern and east-central Texas, but have not
boon found on cotton in northern Texas. (Juno 19): Reports have been
received from 69 farms in 25 counties where control demonstrations are
being conducted. These counties extend from Jim Wells, in the south,
to Grayson,in northern Texas. Flea hoppers are present on 51 of the
farms and are causing injury on 33. (June 26): Fleahoppers are more
widely distributed than during last week, but are in smaller numbers on
cotton in the State as a whole. However, their numbers increased and
more than doubled on the farms examined in Ellis, Grayson, and Kaufman
Counties, in northern Texas, but only in Grayson and Kaufman were they
sufficiently numerous to be injurious. Increased numbers were also found
on farms in Brazoria, DeWitt, Matagorda, Refugio, and Victoria Counties,
but in 8 other counties along the coast and in 3 counties examined in
central Texas there was a reduction in the number of flea hoppers.

A TENEBRIONID (Blapstinus sonorac Csy.)

usual generally over the State and their work was quite conspicuous at
many points. A serious outbreak was found in southern Berkshire County,
where the insects caused almost complete defoliation of many of the
large elms, particularly south of Great Barrington and along the Connec-
ticut Border.

Connecticut. W. E. Britton (June 22): Miany elm and oak trees have been de-
foliated by the spring cankerworm (Paleacrita vernata Peck.), particularly
in the northern and western parts of the State. Such a severe outbreak
has not occurred in these sections in recent years, and property owners
were unprepared for it. Specimens have been received from Bridgeport,
Danbury, Litchfield, and Waterbury. Fall cankerworms have, as usual,
been prevalent in the southern part of the State and some orchard, shade,
and woodland trees have been defoliated.

New York. R. D. Glasgow (June 17): Cankerworms (both species) have defoliated
shade trees in parts of Albany County. The fall cankerworn has been much
less abundant in Westchester County this year than during the last 4 or
5 years.

M. Kisliuk (June 12): On May 30 severe damage to the foliage of
various forest trees, particularly oak and naple, by the spring canker-
worm was noted at the various New York State parks on Long Island. Many

in northeastern Ohio.

J. N. Knull (May 29): There is a severe infestation of cankerworns
in the vicinity of Clifton, in Greene County. Many elm and apple trees
are entirely defoliated. Honoylocust, wild cherry, and white oak also
show severe defoliation. Calosona willcoxi Leec. was present in large
numbers feeding on the larvae.


Indiana. J. J. Davis (Juno 22): Spring cankerworms were more abundant and
destructive in northern Indiana than for many years. Unsprayed apille
orchards wore coL-nonly defoliated; among the' shade trees, eln was most
often defoliated.

Illinois. C. L. Metcalf (June 24): A threatening.outbreak of fall cankerworm
was reported fron Cook and Lake Counties the last of May and the first

tation was noticed in a forest of mixed hardwoods.

Vermont. H. L. Bailey (June 18): Forest tent caterpillars completely defoli-
ating many maple sugar orchards and street tree maples and some elms
in the southern half of the State. Many dead larvae were seen on tree
trunks in Addison County, apparently the result of wilt disease. Cocoons
were found in considerable numbers on June 11. Pupation occurred from
1 to 2 weeks earlier than last year.

Massachusetts. A. I. Bourne (June 25): Tent caterpillars began to hatch
about the 9th or 10th of April and have been unusually abundant, fully
as abundant in the eastern part of the State as they were last year.
Loaf injury has been considerable.

Connecticut. 7. E. Britton (June 22): In Windsor, on June 4, moderate numbers
of caterpillars were observed resting on the trunks of oak trees but leaf

exception of Red River Valley, is overrun with M. disstria. In the Arrow-
head section around Ely and Tower they are very abundant, but the eastern
end of Cook County has the worst devast:ation ever seen there. Everything
is alive with caterpillars. Poplar is the choice frod in this county,
while basswood is the choice in Ottortail County.

remarkable recovery this spring in the lower Hudson Valley. While enor-
mously abundant and destructive a few years ago in parts of Westchester
County, of the lower Hudson Valley, and of Long Island, this insect was
greatly reduced in numbers by the unusually cold winter of 1934. Larvae
and pupae were still relatively rare on untreated trees in the spring of
1935 and later in the saea year eggs were difficult to find where hundreds
were found 2 years ago. On June 10, however, a count on 10 young untreated
trees in Wostchestor County revealed an averago of between 86 and 87 living
larvae and pupae per tree.
