THE :.;CE I:.2RT,'!;T RECOO.S FOR JUIE 1934

The dry weather that prevailed during late May aind well through June ajgra-
vated the grasshopper situation. In general the sections of heavy emergency coin-
cided with those in:licated by surveys conducted last fall in certain States. ITo
surveys were made in Wisconsin and Mlichirar. an', there the situation is much worse
than was anticipated. Over 76,000 tons of poisoned bait purl'l'..-d under a special
appropriation has been alloted to the States, most of it going to generally in-
fested territory.
During June the intensity of chinch bug dCamage increased gre aly., the bugs
leaving the small grains an: in certain sections lamaging corn before barrier
materials became available. The unu-sual weather conditions caused the bug;s to
mature to the adult sta.e earlier than usual. In the cooperative campaign for
chinch bug control carried on under special appropriation more than 1,250,000
gallons of creosote was allottedl to Illinois, over 2,000,000 gallons to Iowa, all
almost 2,000,000 gallons to Missouri. Lesser ar.ounts were allotted to other States
in the infested area. In sore States the allotments from the special appropria-
tion were augmented by purchases made with funds supplied by FZ'A..

Outbreaks of the mor:.'n cricket in Montana and Idaho were larger and did more
danag-e than was anticipated.

The rose chafer is reported as more seriously abundant than it has been for
marny years in the MITw England and Middle Atlantic States, the infestations exten1-
ing westward into Michigan and Indiana.

Flea beetles, attacking corn principally, have be n very destructive this year
in. Indiana, Illinois, Michigpan, and Wisconsin.

The plum curculio emerged so late that little dm:.age is anticipated from the
second brood, with the possible exception of injury to Elberta peacies in the Fort
Valley district of Georgia.

Heavy damage by the beet leafhopper is reported from the Twin Falls district
in Idaho and the Sevier Valley in Utah.

The fall can ker worm is reported as .mu-*,.ally abuant in the eastern part of
1kw En:.land and in New York.

The spring canker worm is reported as abundant from Tew York westward throw-h
Ohio and .i.chig;an to I: 'braska.

The elm leaf beetle is now well distributed over the Boise an0 Payette Valleys
of Idaho, and is seriously defoliating, shade trees.

Losses of cattle from attack by the screw worm are being reported from Florida
and Georgia, indicating the possibility of a repetition of last yeart- 0.iys out-
break of this pest. LlN.AkYf

half of J-unec caused further Cerminction of seed-, better crop growth, and lessened
activity of the insects, an control corm-ipain efforts were much more effective under
these co:-..itions. In Saskatchewan it is Cenerally accepted that in much of the
area of very severe infestation, where the soils are light or medi.u:., there would
have oen little or no crop survival after the broughtt had it not been for the con-

In Eastern CanaoCa local cutworm da-o .a'e, unusually severe in o:r.': sections, was re-

Some losses from wireworms have occurred. in certain localities in southern Al-
berta. In Saskatchewan wireworms have '.one considerable ce:,rcal damae to :r'ps

The winter mortality of the codling mr:th in several localities in southern
Ontario varied %ap*roximatdly from 9 to 52 perce-nt. A ult moths bcan to emerc-e
at the usual period in rdlti-rn to the blooming of the trees. Trouble from this
species is expected in applc-j'o'in: districts of British Columbia.

Aphids are remarkably scarce in Nova Scotian orch.rdls, as a result of urnmsual
autumn weather followed by a severe winter.

In southern counties of Ontario, wher-j San Jose scale occurs, the winter mor-
tality was found to ranre approximately from 55 to $9 percent. The minimum
wi-nter temperatures recorded in the localities stuCdid. ranC;e. from l14 to 25 de-
trees below zero.

Bait-pail records show that adults of the oriental fruit moth survive! the
cold winter throughout .the "Ti-ars 'district, Ontario. The cold, backvard spring,
however, retarded the development of the species.

An outbreak of Crape leaf hoppers is afain present in the -iacera district.

The eye-spotted burcioth and. Brucet s measurinc w orr are more obunddant th n
for several years in the O.1kana 'an Valley, British Col-umbia.

Tear Fredericton, e,,w BrunswicL, infestations of the balsam vwoolly aphid
have been satisfactorily checked by the winterkillin;gl arvae above the snow lin.
Survival was good, however, under the sr.ot,

A careful study of the Erronpoan pine shoot moth in southern Ontario revealed
a mortality of 95 percent or mor. Jurin{n the past unusually sever, winter.

Definite increase of tent caterpillars is reported in parts of 1Tow Brunswidi
NTova Scotia, southern Quebec, and Ontario, the tents of these insects being co44
spic-ouis in r:: .r localities. Tent caterpillars also show an increase in sections
of British Columbia where they have be--;n rather scarce for several eai s. Loc
damage by tent caterpillars is reporte. from the Prairie Provinces.

Scouting for the brown-tail moth in the Maritime Provinces revealed only
four webs near St. Stephen, ": -i Brunswick, and in the se the larvae were lea'.
No traces of the insect were found in Hova Scot:ir.

In Ontario a.n. Quebec, and' probably elsewhere in eastern Car-aa, mosquitoes
are more troublesome than for several years, owing to the heavy winter sn-.-ifall.
Blackflies also are exceptionally n .merous in various localities.

The rhododendron white fly (Dialeurodes chittendeni Lainc. ) was fou.nd- for
;first time in Canada this spring, infesting nurseries in the vicinity of Vancouver
and Victoria, British Columbia. Efforts are being mae to eradicate this pest.

GENERAL FEEDERS

GRASSHOPPERS (Acrididae)

Michigan. R. Hutson (June 12): Grasshoppers are hatching in large numbers.-
in 29 counties of the infested area, which comprises the upper peninsula
and the upper third of the lower peninsula. Some of them have reached
the second instar and poisoning is in progress.

Wisconsin. E. L. Chambers (June 25): Probably the most serious epidemic of
grasshoppers ever experienced in Wisconsin apTeared this season, certain-
ly the worst in the memory of the oldest residents. Thirty-five counties
in the northern half o-' the Stote received both State an6 Federal aid in
addition to large sums spent by the counties themselves so long as their
credit lasted. Arsenic sufficient to make up 9,500 tons of the poison, in-
cluding 2,000 tons of ready-mixed bran furnished by the Government, was
distributed.

Minnesota. A. G. Ruggles (June 26): Grasshoppers are very abundant in 40
counties. Farmers are frantically callir.-: for poison bait. The infesta-
tion is much worse than was expected.

North Dakota. J. A. Lunro (June 14): Hatching of the various economis species
has continued up to the present. According to F. D. Putcher, C2irnula
Zellucide Scud. is very abundant in the northern rart of the State, while
Melanoplus mexicanus Sauss. and :_. bivittatus Say are :-nerally distributed.
2he recent railfall over the hopper-infested area has been followed by
heavy hatching,.

Iowa. C. J. Drake (June 25): The rasshopper infestation in western Iowa
extends alon-L the Missouri River r,.r, Sioux, PIcu', a'd Cr3:-.rd
Counties to Taylor, irenmont, and Page Courties, a t'l o(f 1G counties.
Over 250 tons of poisoned bait have been used in tlc se counties.

I:braska* 1.:. H. Swank (June 20): The grasshopper situation developed with
unexpected severity during the second half of Hay an the early part of
June. The heaviest early infestations were in the northeastern corner
of the tr.te. As the month advanced serious uijtbreaks develop-.... across
the central part of the State to the southwestsri corner and northv.ard
into the namnhraule. A total of 1,880 tons of bait Iurnished by the
Federal Coe--rra.:n.nt has been distributed.

Kansas. H. R. Br:,iton (June 26): Grasshoppeir. are very nbund-:t. in some sec-
tions of the State, but about as abundant as usual at 7'aid],attan. Re-
ports of infestations have been receive-d fro.. FI-ru.

Texas. E. WV. Laake (June 23): Grasshoppers are very aburndciiit in E3llas
County.







129


Montana. A. L# Strand (May 29): The grasshopper campaign is well under way,
Hatching of the eggs began at lest a month earlier than in 1933. The
infestation is developing very much in accordance with the survey, M.
bivittatus has hatched almost completely and some are nearly full grown.
The lesser migratory grasshopper (M. mexicanus) has been slower in hatch-
ing but probably 80 percent of the eggs are now hatched.

Idaho. C. Wakeland (June 19): Grasshopper control has been progressing
very satisfactorily and to date the State has shipped in 670 tons of
Federal poisoned bait. Nearly all damage has been prevented, but hop-
pers have reached the migrating stage in some areas and co-nsiderable
difficulty is being experienced in protecting cultivated lands along the
margins of desert areas.

Arizona. C. D. Lebert (June 25): Winged adults of our early hatched grass-
hoppers are practically exterminated in all fields where the poison was
used. Late hatching of M. mexicanus has been noticed in two fields to
date. It is too early to determine to whet extent this late hatch may
develop.

Oregon. D. C. Mote (May 28): .A Federal grasshopper control campaign is be-
ing undertaken in Klamath, Lake, Harney, Creek, Deschutes, and Grant
Counties. C. pellucida is the most abundant species involved.

California, E. 0. Essig (June 24): Grasshoppers are abundant in a few scat-
tered localities.

MORMON CRICIET (Anabrus simplex Hald.)

Montana. A. Lo Strand (May 29): The outbreak in southern Montana is far
more serious than was expected, but in general conforms to the egg survey
made last summer* Crickets are also appearing in several northern
counties. In some of these there are, probably not enough crickets to
do much damage this year.

Idaho, C. Wakeland (June 19): Mormon crickets are a month earlier than
usual, most of the eggs having already been deposited. A few instances
of severe injury were encountered this year in the upper Snake River
Valley, the first r-R1,dG;a~ge we have observed in the 3-year fight we
have had with them.

VARIEGATED CUTWORMI (Lycophotia margaritosa saucia Hbn,)

Oregon, D. C.G Mote (-May 28): Cttworms were found injuring hops on 11ay 21
near .Independence and Dayton. In certain areas every hill contained
from 1 to 20 worms and had two thirds of the shoots cut off.

ARLJiYORI.1 (Cirphis unipuncta Haw.)

Indiana. J, J. Davis (June 22): Moths have been abundant and there is every
likelihood of outbreaks in the near future,

Illinois. W. P. Flint (June 23): There have been several slight-to-moderate
outbreaks,











Visconsin. E. L. Chambers (June 25): Armyworms are originating usually in
s-aFn lands in marsh hay fand are moving out and destroying thousands of
acres of valuable crops before bein- brought under control in one of the
worst epidemics this State has ever experienced. State aid in supply-
ing poison and assistance ih directing the control measures has .already
been given to more than dozen counties.

C. L. Fluke (June 21): Armyvorms are very numerous on 1,000 acres of
marsh grass in Manitowoc County; and on corn in Washburn and Dodge
Counties.

P'innosota, A. G. Ruggles (June 26): Cirphis unipuncta Haw. is very bad in
Houston, Freeborn, *..'aseca, Otter Tail, and Mille Lacs Counties.

Iowa. C. J. Drake (June 25): Army.06rms'have done considerable daTare local-
ly to rye and wheat in Hamilton, Webster, Story, and two or three other
counties. Most of the worms are apparently free from parasites.

H. E. Jaques (June): The armyworm has been reported from Osceola,
Pocahontas, Tima, and Poweshiek Counties.

.WHITE GRUBS (Phyllopihaga spp.)

New Hampshire. L. C. Glover (June 25): There is severe damage to white pine
seedlings in ::errimrnack County.

I.aryland. T. A. Hyslop ('Jay 23): A heavy flight of June beetles (P.kr.ochi
Gyll.) was observed on May 23 at Avanel, .(Det. by E. A. Chain)

i.ichigan. E. I. McDaniel (June 14): June bug.D are abundant throughout cen-
tral and southern Michigan and the foliage hss been practically removed
from walnut, oak, and hickory. P. hirticula Knoch is the rredomir.ating
species.

Minnesota., A. G.Rufrles (June 26): Jhite grubs are very abundant in a
number of counties.

Iowa. C. J. Drake (June 25): Some injury is showing up in a lnrre number of
counties in western Io02a. A considerable T-_rcontaae of the over-vinter-
inr grubs are still-in their hibernating cells many inches beneath the
surface of the soil.

Nebraska. 1I. H. Swenk (June 20): Vihite grubs are r Eorted as extensively
destroying the roots of Black Hill spruce trees in York County on June 8.

A ,'I'.'CRM (Heterode-res laurentii Guer.)

Alabama. K6 L. Cockerham (M!ay l6): Baldwin County has started movinr: its
9,000-acre potato crop. Wireworm injury is more serious than for the
past several y:-.ars. It is estim t-d that 50 9r-rcent of the cars are
graded under No, 1 because of da:.age. On some farrs frcm 20 to 30 per-
cent of the potatoes are injured.






131


PLAINS FALSE WIREWORM-(Eleodes opaca Say)-

Nebraska. M. H. Swenrik (June 20): Adults were reported as very abundant in
Chase ahd Box Butte Cotnties on June 8 and 12, respectively. The Box
Butte County correspondent- stated that they were so abundant at night on
the road about 4 miles west of Alliance that a truckload of them could
have been shoveled up in a mile.

SASIATIC GARDENBEETLE (Autoserica castanea Arrow)

New York. H. C. Hallock (,June 23): Larvae have been found in grrdenis that
were cultivated last year. They are destroying beets, carrots, corn,
squash, lettuce, and asters. It was necessary to replant at Larchmont,
Oyster Bay, Locust Valley, Port '.ashington, and Great Neck.

JAPAITESE BEETLE (Popillia japonica Newm.)

New Jersey. C. H. Hadley (June 12): The Japanese beetle season has started.
General field emergence of the adults from the ground started at Moores-
town on June 11. On that day a number of beetles were found in the field.

ROSE CHAFER (Macrodactylus subspinosus Fab.)

Maine. H. B. Peirson (June 20): The rose chafer is abundant at Augusta and
is feeding on elms at Saco.

Connecticut, M. P. Zappe (June 14): Adults are unusually numerous and de-
structive to plum, grape, and ap-ile foliage and fruit in the eastern
part of the State and to corn at New London.

New York. N. Y. State Coll. Agr. News Letter (June): The rose chafer ap-
peared the first week in the month in the Hudson River Valley and did con-
siderable damage during the second week of the month in this region and
in Niagara County.
New York. P. J. Parrot (June 25): M. subspinosus is very abundant in some
places in the v:estern part of the State.

Iewv Jersey. -I. M. Hawley (June 11): The rose chafer is numerous, beetles
are entirely destroying roses in ornamental gardens.
Maryland. E. N. Cory (June 21): There is a heavy infestation at Cambridge.

Indiana. J. J. Davis (June 22): The rose chafer was reported on June 2 as
damaging peaches at Goshen.
Michigan. E. I. McDaniel (June 14): The first rose chafers in the vicinity
of lansing appeared about June 12. They were feeding on apples in a
large orchard. In other years they have been very destructive to
peonies and roses.

Ray Hutson (June 22): The rose chafer is causing some damage to corn
at Okemos, and is attacking fruit trees at Williamsburg.
Wisconsin. E. L. Chambers (June 25): Rose chafers are appearing in destruc-
tive numbers in Monroe, Jackson, and Waushara Counties, where they are
injuring flowers, garden crops, and field corn over large areas of light
sandy soil.





132


CDLI0N RED SPIDER (Tetranychus telarius L.)

South Carolina. J. A. Berley and W. C. Nettles (June 23): Damnaging flowers
and ornatentois, often starting from sweet peas.

Indiana. J. J. Davis (June 22): Reported damaging evergreens at Plymouth June
13, and beans and sweetpotatoos at Richmond June 19. Destructive in dahlia

Mississippi. J. M. Langston (June 22): Reports of infestations on arborvitae
and other ornamentals received from various sections during the last month.

Nebraska. M. H. Swenk (June 20): Red spiders r-ported working heavily on jack
pines in Phelps County May 20 -nd on cedar trees in Chayennr County May 29.

Idaho. C. Wakeland (June 19): Following the unprecedented outbreak of red spi-
ders last year arnd the mild winter succeeding, we ho-ve been expecting a very
serious infestation this season. Normal date past when red spiders begin
to severely injure trees. Many sections free of red spiders and only very
mild infestation on the lower leaves of Delicious apple trees.

Utah. G. F. KIno-.lton (June 12): Damaging raspberries at Butlerville, Salt Lake
County.

California. Kern County, Mo. News Bull. (June 1): Proving a serious and per-
sistent pest. Many sycamore trees have turned completely brown from the
attacks. Trl-s sprayed before injury are still in good condition. The
earliest injury to sycamore and other deciduous trees in the history of this
office. Preparations are being made to spray some trees the second time to
prevent injury,

CEREAL AND'FORAGE-CROP INSECTS

WHEAT AND OTHER SMALL GRAIiL

VWHEAT HEAD AR.7YWVORM (Neleucania albilinea Hbn.)
Maryland. E. N. Cory (June 21): This armyworm is doing considerable d&.mnge to
wheat along the edges of fields near Adnmstown, Frederick County.

W"-[AT STEII lAGGOT (M'eromyza anericana Fitch)
Kansas. H. R. Bryson (June 26): The wheat stem megot reported to be injuring
wheat at Topeka,

ENGLISH GRAIN APHiID (Macrosiphum grsn.-rium Kby.)
Indiana. J. J. Davis (June 22): The rrf.in aphid was reported as very abundant
on whE.at in a number of localities in southeastern Indir.nr during the first 2
weeks in June; however, ladybird beetles hnve cleanedd up the infestations.

iAPHID (Pemphlgus brevic-rnis H-r.rt)
:.braska. M. H. Swenk (June 20): Specimens of this aphid were sent in on June 8
from Butler County, where they were causing sever- damage to the roots of
wheat plants, A similar report came .from Snaline County on June 19, where
this or another sr,-cies was infestir.n the roots of barley plants.

RIcE S'IN1:?UG (Solubea pugnox Fab.)
Ok1- h Co. C. F. Stiles (June): The rice stinkbug has b.:.n rep.'rtud fromin McClaln
County as i-em-irn, oats by sucking the milk out of the developi6g:;FXnn.






133


CORN

CHINCH BUG (Blissus leucopteruis Say)

New Hampshire. L. C. Glover (June 25): The chinch bug has been reported as
doing serious injury to golf greens in West Hopkinton.

New York. E. P. Felt (June 22): Chinch bugs are present in considerable
numbers in a lawn at Scarborough. This insect has caused serious damage
on golf greens and lawns in this.general area during the last few years.

Indiana. J. 5. Davis (June 22): In seven northwestern counties, the chinch
bug killed wheat and rye and began migrating into corn much earlier than
usual. The losses will be very severe. In the .southwestern part of
the State from Vincennes north and in the eastern and northeastern sec-
tions the bugs are very abundant, but conditions are much more favorable
for control by use of barriers. In these sections, although seriously
affected by drought, the bugs are remaining in the wheat and rye until
about harvest time. The government aid in furnishing creosote is much
appreciated by the farmers. The chinch bug is about a week or 10 days
ahead of normal. On May 16 we found the first hatchiri eggs. On June
20, we found the first winged adults of the first generation at Lafayette.
Forty-two counties are known to be infested to the extent that control
measures are necessary and I feel certain that the final check-up will
find all counties north of a diagonal line from Know County on the west
to Randolph County on the east, to be infested to a noticeable degree.

Illinois. W6 P. Flint (June 23): Chinch bugs have been extremely destruc-
tive during the past month in nearly all parts of the State, owing to
the drought. They left the small grain before it was cut. It is es-
timated that more than 200,000 miles of barrier have been constructed
within the State.

Michigan. R. Hutson (June 22): Chinch bugs are very abundant in Berrien
County, at Galien and at ITew Buffalo.

Minnesota. A. G. Ruggles (June 26): Chinch bugs are very abundant in a few
counties.

Wisconsin. E. L. Chambers (June 25): Chinch bugs are beginning to appear
in a few of our southern and western counties, but are not yet doing
serious damage.

Iowa. C. J. Drake (June 25): The infestatin is probably the worst in the
history of Iowa. The bugs are doing damage in 0bO counties. In 40
southern counties the bugs have destroyed from 75 to 90 percent of the
small grain--barlay, oats, and wheat. In a few counties the county
agents estimate that less than 2 percent of the_.rrmall grain will be
harvested or cut for forage. In mafy counties the farmers will do very
well to save one half of the corn crop. The northmost records of migra-
tion from anall grain to corn being from Story, Benton, Jones, and Jack-
son Counties. Light infestations have been reported in a few counties
in the northern part of the State. Over 2,000,000 gallons of creosote
coal tar have been used this summer. The County Agent of Monroe County









stated that the farmers were very much concerned about pasturing cattle
in small grain fields heavily infested. In one instance a farr.-r re-
ported the death of a cow from feeding upon small grain plants covered
with the bugs. A post-mortem exainetion of the cow showed thousands
of chinch bugs in the intestinal tract. The veterinarian diagnosed the
cause of the death as the result of toxines from the bugs.

Missouri. L. Baseman (June 25): ;io are rapidly drawing to a close the
greatest active cR::peign of control against this pest that Tissouri has
ever been called on to wage. The Federal cooperation came just in time
to largely save the day. About 1,250,000 gallons of barrier oil have
been furnished by the Federal department, saving a good many millions
of bushels of corn. Bugs will continue to migrate until the first of
July in some counties, but the available supply of oil will about take
care of our needs. About 70 counties have bean heavily infested and
20 or 30 of these most seriously*

rebraska. IJ. H. Swenk (June 20): Late in May and early in June a very
severe infestation of the chinch bug developed in southeastern Nebraska,
extending north into Em't-ler, Saunders, and Sarpy Counties. Less severe
infestations involving serious crop destruction occurred in the four
counties imeedirtely west of this area. A separate infestation of less
severity developed in south central Nebraska. The ni-ration started
fully 10 days earlier than the earliest beginning of a chinch bug migra-
tion previously recorded (June 12, 1933), and nearly 3 weeks ahead of
the average beginning of migration (June 21).

Kansas. H. R. Bryson (June 26): Chinch tugs began migrating at Manhattan
on June 1 and reached the peak of migration on June 14. They are very
abundant in the eastern two fifths of the State. Extensive use was
made of dust and creosote barriers, The adults were flying to other
fields on June 19 and 20.

CORN ROOT APHID (Anuraphis ijaidi-radicis Forbes)

Iowa. C. J. Drake (June 25): The corn root aphid has been reported from a
l&rge number of counties in Iowa this spring. In several instances the
fields are so heavily infested and badly injured that the farmers have
given up trying to grow corn and are replanting the fields to soybeans*
In Story County the aphid was found in l-r.e numbers feeding on the roots
of melon plants, an unusual record for this insect.

COFi- EAR ",OR. (Heliothis obsoleta Fab.)

North Carolina. R. W. Leiby (June 14): Tho corn ear worm is either r-ore de-
structive than usual on commercially gro'.rn corn in the eastern part of the
.tate or there is more than the usual interest in preventing damage.

South Carolina. W. C. Nettles (June 23): The corn ear worm is damaging
'o'ung tomatoes at Clrmson College. In the eastern section it has damaged
seed heads of flax in experimental plantir.nt.z.

lo:a, C. J. Drake (June 25): iany farmers, especially grov:ers of sweet corn,


134






135


are asking about the corn ear worm. Apparently the insect is widely
distributed in the State and may do a considerable amount of damage.

Kansas. H. R. Bryson (June 26): The corn ear worm is very abundant. A
considerable amount of damage has been done to the curl of the corn
plants. The insect also has been reported injuring tomato fruit at
Canton and Wichita.

tremely destructive outbreak of the rough-necked cornstalk beetle in
the southern third of the State.

C. L. Metcalf (June 20): The sugarcane beetle has been reported as
very destructive to corn in Hamilton County. The injured field of corn
and soybeans adjoins 160 acres of bottom land, most of which is in cul-
tivation this year for the first time in 4 years.

Mississippi. J. M. Langston (June 22): On June 9 a grower at Dorsey,
Itawamba County, sent adults to this office, with a report that they
had severely injured young corn. Complaints of injury were also re-
ceived from Rockport, Coriah (obinty, during- the latter part of May.

FLEA BEETLES (Halticinae)

Indiana. J. J. Davis (June 22): Flea beetles are the second most important
pest of field crops in Indiana. The pale-striped flea beetle (Systena
taeniata blanda Melsh.) is the predominating species attacking corn and
by far more abundant than I have ever known it to be. Specific records
include: At Connersville, in one field, 216 tomato plants destroyed in
one night; at Goshen, 30 to 40 percent of corn taken in some fields,
also attacking soybeans, Canada thistle, morning glory, and milkweed; at
Fort Wayne, destroying corn and truck crops; at Hamilton, a 16.-acre field
of corn was destroyed and other cornfields were seriously dnlaged; a
serious pest in corn fields at South Bend, Rochester, Albian, and Topeko.
All of these infestations are in the northern half of the State.
Striped flea beetles (species unknown) were reported damaging corn, beans,
beets, and potatoes at Aurora, Avilla, and Danville on June 1 to b, and
the black potato flea beetle was reported from Aurora, Avilla, and North
Judson on June 1, 6, and 15, respectively.

Michigan. R. Hutson (June 12): We are having trouble with the pale-striped
flea: beetle on field corn in the southern tier of counties. (June 13):
The pale-striped flea beetle was reported today from several points in
the northern half of the lower peninsula.

Wisconsin. E. L. Chambers (June 18): The pale-striped flea beetle has been
unusually abundant this month throughout the south central portion of the
State, destroying large acreages of corn and potatoes.









COR:i BILLBUGS (Calendra spp.)

Ihdiana. J. J. Davis (June 22): Billbugs (species undetermined) were very
destructive to several fields of corn, according to information received
on June 180

Minnesota. A. G. Ruggles (June 26): C, aequalis Gyll. reported front Redwing
and St. Paul on corn; C. pertinax Oliv. iMarshall reported on corn.

Iowa. C. J. Drake (June 25): Many fields of corn here and there have been
badly injured or entirely destroyed by billbugs (several.species) this
spring.

:orth Dakota. J. A. Munro (June 14): The clay-colored billbug (C. aequalis)
is reported as very abundant in a farm yard at Eldridge, Stutsman County.

Nebraska. M. H. Swenk (June 20): Timothy billbugs (C. parvulus Gyll.) were
reported to be destroying corn on May 2.6 in Richardson County. The
clay-colored billbu.::, was reported as destroying corn in Madison County
on June 7. On June 20 a Lancaster County farmer brought in some corn
destroyed by the latter species.

Alabama. J. M. Robinson (June 23): Corn billbugs are moderately abundant at
Spring Hill.

ALFALFA

ALFALFA MWE/IL (Hypera postica Gyll.)

Idahoo C. Wakeland (June 19): No injury is reported in southern or south-
western Idaho but the weevil is seriously injuring alfalfa in the upper
Snake River Valley where spraying is being done for control.

California. A. E. Michelbacher (June 23): Over its entire range in central
California the alfalfa weevilA has shown an increase in numbers during
the past month. One June 15 as high as 122 larvae to 100 sweeps were
collected in the Tracy area. About Pleasanton on June 18, counts as
high as 225 larvae were taken, while in the Niles district collections of
over 1,000 larvae were made, ITot of the larvae collected were small,
many being very small. Many of these larvae are evidently the beginning
of a second brood.

SUGAR CA.IE

SGiRCAICE PLZTLE (Euetheola rugic-.F Lec.)

Louisiana. J. W. Ingram, W. A. Douglas, and E. K. Pynum (June): Beetle in-
jury in the sugarcane section a.:rs 1rctically over the last of June. The
heaviest injury occurred during May. Loss from injury to sug-rcone was
40 to 50 percent less than in the 5 years. This decrease was du. partly
to the growing of varieties gi.' ir" a larger rnuibzEr of plants per acre and
hav'nr greater recovery ability on lana that is subject to heavy beetle in-
jury, and in part to increase-d rainfall at the time of injury, which stimu-
lated growth and increased recovery.

F.RUI T INSECTS

APPLE

CODLING .'OTH (Carpocapsa pomonella L.)

Delaware. L. A. Stearns (June 23): Energence of spring-brood moths ended
by June 14; peak of first-brood larval entry, June 7 to 14.

South Carolina. F. Sherman (June 23): The codling moth is apparently less
abundant than normal at C.lemson College.

Georgia. C. H. Alden (June 23): Codling moth moderately abundant at Cornelia,
first brood moths appearing it numbers on June 17.

Indiana. J. J,. Davis (June 22): Codling moth is as abundant or riore so
than in 1926 or 1930, and the second-brood worms will be appreciably
earlier than usual. In many regions more than the usual number of
sprays will need to be applied.

Michigan. Ray Hutson (June 12): Adults became active in Berrien County
on May 18, more than a week earlier than any marked flight was noticed
a year ago. Exceedingly hot weather has brought the peak of emergence
at least 2 weeks before the usual date.
a
Wisconsin. C. L. Fluke (June 23): The codling moth is more abundant than
last year. The peak of emergence was reached on May 31.

Missouri. L. Haseman (June 25): The situation is again serious. Most of
the first-brood larvae were out of the fruit by June 20, indicating that
the July brood of moths will be heavy and bunched.

Minnesota. A. G. Ruggles (June 26): The codling moth appears to be rela-
tively scarce. It will have only a few apples to feed on, as the drought
has caused a tremendous drop.

Kansas. H. R. Bryson (June 26): The codling moth is about as injurious
as usual in Doniphan County. Hail in the vicinity of Atchison damaged
apples so that increased injury by the second brood of codling moth can
be expected.

Oregon. B. G. Thompson (May 28): Codling moth depositing considerable
number of eggs the last few days. First moth found on May 21.

California. E. 0. Essig (June24): The codling moth is moderately abundant.

Wallingford, where it appears to be increasing. Larvae observed in
many orchards surrounding those heavily infested.

Indiana. J. J. Davis (June 22): The fruit tree leaf roller was reported as
very destructive at Saint Joe on :'ay 24, the first report of abundance
of this insect received during the past 10 years.

abundant*

PEAR BORER (Synanthedon pyri Harr.)

Virginia. W. S. Hough (June 4): The pear borer is very common on apple
trees in commercial orchards at Winchester. The borer seems to be es-
pecially active on trees thet were weakened by the 1930 drought. The
moths are emerging in large numbers at this writing*

RASPEFRRY CiLIL BORER (Oberea bimaculata Oliv,)

Indiana. J. J. Davis (June 22): The raspberry cane borer was reported as
destructive in commercial dahlia ir-.ens at Dublin.

A FLEA I.&LE (Haltica foliacea Lec.)

Kansas. H. R. Bryson (June 26): A gre r flea beetle, H. foliacea, :.as re-
ported injuring, seedling apples at Saint George, Wathena, and Topeka, as
well as at several places along the Kansas River Valley. Also reported
attacking poppies at M:anhattan.

APPLE LZAF-GURLI:C, PIDGE (Dasyneurs mali Kieff.)

'a.,j achusetts. A. I. Bourne (June 25): Professor Whitcomb reports that the
appla leaf-curlir.r midge is very abundant elon he ,north shore.

APHIDS (Aphididae)

Conneaoicut, P, Garman (June 23)r Green aphids (Aphis p2oi DeGj present
throughout the season- inNew Haven, Hartford, and Middlesex Counties, but
kept in check by enemies. Thie rosy aphid (Anuraphis roseus Bak.) is
scarce.

New York. N. Y. State Coil. Agr. News Letter (June): The apple aphid
during the last week in the ronth became- noticeably abundant in the
Hudson River Valley and in the western fruit-growing section. During
this period the rosy aphid began to appear in numbers in western New

14o


Kansas. H. R. Br:.'son (June 26): aposca sp. reported to be causing
considerable injury to apple leaves in orchards in Doniphan County.
There is a possibility of serious injury resulting within the next 2
months if steps are not taken to control them.

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

Massachusetts. A. I. Bourne (June 25): As yet very little evidence of
San Jose sale is apparent, indications being that there is a consider-
able winter mortality.

Maryland. E. N. Cory (June 21): The San Jose scale is very abundant in
Anne Arundel County.

Georgia. 0. I. Snapp (June 15): Predators and parasites are abundant in
peach orchards that have been heavily infested with the San Jose scale
in Fort Valley, and during the last 2 months they have materially re-
duced that orchard pest.

PEACH

ORIENTAL FRUIT MOTH (Grapholitha molesta Busck)

Massachusetts. A.I.Bourne (June 25): The infestation is very general over
the entire peach-growing sections of the State but it is quite variable
in each section. In some commercial orchards where for the previous
years the insect has been very abundant, it is now difficult to find.
We note the greatest reduction in abundance in those sections where
parasites have been liberated in greatest numbers.

Connecticut. P. Garman (June 23): First brood abundant in some orchards
in New Haven and Hartford Counties. Larval parasites of the first
brood scarce; egg parasites present in some places. Winter conditions
may be responsible for low parasitism.

New Jersey. H. W. Allen (June 8): The catch of moths in bait pans from
the overwinterin,- brood has been slightly higher this spring than last
and much higher than in 1931 and 1932, averaging at the peak more than
10 moths per day, per pan. Twig infestation has also been moderately
heavy.

Pennsylvania. H. W. Allen (June 2): On May 25 and 26 a moderate infesta-
tion of peach twigs was found in orchards in Franklin County, but a
much heavier infestation was found on the other side of the mountain in
Adams County.

Delaware. L. A. Stearns (June 23): Twig injury by oriental fruit moth just
appearing June 20.

Maryland. E. N. Cory (June 21): The oriental fruit moth is very abundant.

H. W. Allen (June 8): On May 21 very little infestation of the twigs
of peach by first-brood larvae could be found in Dorchester, Wicomico,








141


or Worcester Counties. On May 24 a heavy infestation of peach twigs was
noted in many orchards about Smithsburg, Washington County.

Virginia. H. W, Allen (June 8):' On May 16 and 17 first-brood infestation
of peach twigs was moderately heavy in many of the orchards in Albemarle
County and heavy in Augusta County.

Georgia. 0. I. Snapp (June 19): Some damage to terminals of twigs of non-
bearing peach trees in and near Fort Valley, but of no importance in
bearing orchards of this district.

C. H. Alden (June 23): A light twig infestation by the oriental fruit
moth was noticeable on June 19 at Cornelia.

Mississippi. J. M. Langston (June 22): Peach twigs injured by larvae have
recently been received from Greenwood, Leflore County.

PEACH BORER (Aegeria exitiosa Say)

New Jersey. R. C. Burdette, B. F. Driggers, and C. C. Hamilton (June 27):
The peach borer is moderately abundant.

Georgia. 0. I. Snapp (May 31): The first cocoon (pupa) of the season was
collected from a peach tree in Fort Valley today. An empty cocoon
with cast pupal skin, indicating that adults had already emerged, was
also found today in the same tree. These are the earliest records for
this latitude. The tree was infested with insectary-hatched larvae
on July 20, 1933. (June 18): The first moth (female) of the season
emerged today in Fort Valley. This is the earliest moth emergence date
on record for this latitude under peach orchard conditions.

PLUM CURCULIO (Conotrachelus nenuphar Hbst.)

Massachusetts. A. I. Bourne (June 25): The plum curculio is present in
normal numbers.

Delaware. L. A. Stearns (June 23): First-brood grubs are in the soil. The
infestation of the short peach crop is moderate-to-severe.

New Jersey. R. C. Burdette, B. F. Driggers, and C. Co Hamilton (June 27):
The plum curculio is moderately abundant.

Maryland. E. N. Cory (June 21): The plum curculio is very abundant. Typi-
cal killing of twigs on peach is noted.

Georgia. 0. I. Snapp (May 28): The first pupation of the season took place
today at Fort Valley. The cold rainy weather in May retarded the develop-
ment of the curculio in the soil, and as a result it is doubtful whether
there will be a second brood. Usually only one generation occurs in
this latitude when pupation is as late as the last of May. Cool weather
continues and will undoubtedly prolong the pupation period. (June 6):
The first transfonnation to adult beetles in soil cells was recorded
today. (June 13,): The first new beetles of the season emerged from
the soil today. This is 17 days later than the first emergence last year&







1'42


On account of the late Energence of first-generation an attack by the
second brood is not anticipated, except perhaps in the Elberta, which
is the last variety to move. (June 19); There has been no egg deposi-
tion by the second generation to date.; (June 22); Fdirst-generation
adults are now emerging in large numbers. Jarring during the past
week show an increase of over 300 percent in the number of adults.

-Tinnesota. A. G. Ruggles (June 26): The plum curculio is very abundant.

:-'ichifan. R. Hutson (June 12): Both the dark-banded and the li:ht-bar.ded
cherry fruit flies have emuo.rged earlier tlnn usual. The dark-banded
(R. fausta. 0.S.) was first obt.iri.'d on Friday, June 1, at Gobles, and
the white-banded (R. cingulata) was first taken this -'cor at Saint
Joseph. The emergence of both species was exceedingly rapid and







143


progressed from the Indiana line to the Grand Traverse district, prac-
tically 300 miles north, within a period of 1 week. The dates for
emergence of the dark-bodied flies were June 4 at Grand Rapids and June
6 at Shelby, while the white-banded fly was taken at Beulah on June 7.
(June 22): R. fausta emerged on June 14: at Northport and R. cingulata
emerged on June 13 at Traverse City.

year in the Flathead Lake region. The stem mothers appeared on the
buds as early as Mlarch 15 and spraying began on the 20th.

CHERRY LEAF BEETLE (Galerucella eavicollis Lec.)

Virginia. W. J. Schoene (June 6): A small red beetle has been reported as
doing considerable damage to young foliar-e on cherry and peach in Rocking-
ham and Augusta Counties. The same insect was reported at this season
of the year in 1933. (Det. by H. S. Bakber)

PLUM

THISTLE APHID (Anuraphis cardui L.)

FALL CAIKER WORM (Alsophila pometaria Harr.)

Massachusetts, Connecticut: Rhode Island, and !Tew York. J. V. Schaffner, Jr.,
(June): Several reports have been received on the c.bundance of this pest
in eastern Massachusetts. The earliest spraying operations carried on by
cities and towns against the gipsy moth and elm leaf beetle undoubtedly have
prevented much defoliation by A. pometaria. In the Blue Hill section of
Milton, Mass., from 50 to 100 acres of woodland and many shade trees of elm,
oak, and ash were reported to be from 50 to 100 percent defoliated on June 6.

the vicinity of T.-'w Maven and IT)rth 3ranford, Conn., are quite badly infested.
On May 31 many shade trees and cn-r woodlarn! areas in the vicinity of Crans-
ton, R. I., were from 25 to 100 percent defoliated. On June 4 to 6 severe
infestations were noted on 1:h.d.'; trees, particularly elm, in apple orchards,
oak woodlan-s, and in wastelands *rowing up with wild cherry and other de-
cid.ous growths. Woodland stripping is quite prominent in many localities
as far north as 3 fordd Township. Many large elm shade trees are completely
defoliated. In the northern part of this area some of the stripping in the
oak woodland is due in part to the abundance of Phigalia titea Cram.,
Erannis tiliaria Harr., and other native species.

festations in Washington County, Maine, with defoliation estimated in some
places up to 25 percent,have been reported. This species was abundant on
sugar maple ha..e trees in Walpole, IT. H., on May 27. C. W7. Collins noted on
June 21 that larvae were generally common in woodland wherever stops were
made between Durham, N. and all towns surrounding Lake Winnepesaukee.
At Farmingtor, U.1 H., some 30 ash and maple shade trees were from 50 to 100
percent defoliated.
