::l- I;COC II PO." : ?.-'TCO~rS ?OR APRIL, 1932

Cll.?.tic conditions duarin- the month of April were favorable for
grasshoppers over the greater part of the heavily infested territory,.
Reports of the activity' of those unimportant species which overwinter
as nmmphs were cuite generally received from the entire Mississiopi
Valley. Up to the last wee: in the month no hatc.in., of Melanoplus or
Camnula was reported.

Cu-tworms. of several species were all',rinz in limited areas over
practically. the entire coutntr-. In the vcerlades district of Florida 100
acres of su arcane were strip ed and tobacco was also being cd_. n;ed in
.that State and in :Torth Carolina. Alfalfa wasbein seriously dared
over a large area in Est-Central -Tebraska by Exnoa messoria Harr. Here
the cutwormn was assimninT somewhat armuvworm-like habits owing; to its
enorrious numberss.

By the third weekI in April practically all Hessian flies in the 11st
Central States hiad pupated; and during, the latter half of the month there
wn.s soc er.ergence in parts of this area. The extremely cold weather dur-
in'- the middle of 7,'rch was evidently very disastrous to the .:p. in the
eastern p.rt of this area, Ohio reportin ti'at the insect wa.s very diffi-
cult t+ find in most parts of thec State visited. In Illinois, Missouri,
and I'e='r?.c-', however, the insect -.-s still present in threatenin- n:.r bcrs.
In Illinois a:. r:i'?.tel, 90 por cent of the larvae and pupae have survived.
Z a: layini was well unacr wa-, in that section throughout the month, y7ung
larva;: havin; boon observed in 1'issouri by the 15th.

Scattcrc. ':-r' rat-er light flic-:ts of chinch bz-.s occurred during
the firste"- wo )f te :.-:-'th in illinois; anc -)resent indications are that
these insects will -be tr-ublesone in central Illinois and0 Missouri.

P.potion of the codlmin- mth started in the iliddle Atlantic, ast
Ce-ntral, i:nd Test Central States during the third week of April, at which
time pupation was about one-third completed in t'he Pacific :T:hrthiwcst.

Dulri:,F the third week of the month eo.er.e..ce bean in Georgia W&d south-
ern Missouri. In the Southwest emer7e-.ce was observed during: the first
week in the month, and moths were abu:".d.3nt in bait pans in :Te-, Mexico by
the 10th. In southern California e-Ts were observed during the third
week in the mrn):th.

r.uit aphids were reported as generally scarce throughout the New
.=larid States. A moderate abundance of these insects w.s reported from
the middle e Atlantic States, and but sliqzht abundance in the South Atlantic
States. In The East Central States those insects were moderately abundant,
and appeared to be decreasing in Illinois and Missouri.

Fggs of the oriental fruit moth were observed, in northelstcrn Georia
onr April 18, by which time over 70 per cent of the overwinterin. larvae
ihad pupated and about a third had emer:oc' as adults. The first emiergence
in Virginia was observed on April 14 and the first c.-rs were found in
that State on the 22d. By the third week: in April ip:ption was practi-
cally completed in Delaware. No pup':tion hd taker, place by this time,
however, in western Nev.; York.

The plum curculio was first collected in the field in Tennessee on
April 4, In Georgia on April 5, in Virginia on April 6, and in Delaware
on April 20. This is the latest appearance of adults in the past 12 years
in Georgia.

The vegetable weevil is spreading gradually in the Gulf section.
During late March and early April it wss found in 2 counties in the south-
eastern corner of Arkansas, in 18 additional parishes in Louisian:a, a..nd
in 1 additional county in Texas.

The Colorado potato beetle was reported i.n u-:prsce.-2ented numbers
from the Gulf coast of Alabama and Mississippi.

Ove-rinterig.- adults of the .exican be"?. beetle seem to have passed
the winter exceptionally well as far north as Con._eccticut, and adults
were cMcrrin- from hibernation quarters during the third week in April
in outdoor cges in Delaware.

C. L. Fluke (April 25): E-s of Camnula nellucida Scudd.,
are very numerous.

H. C. Severin (April 20): Egs are very abundant in gen-
eral over South Dakota; not hatched as yet.

M. H. Swenk (March 20 to April 20): Additional reports of
an abundance of grasshopper nymphs in the fields continued
to come from northern Nebraska during late March and early
April. The green-striped grassho-o-ner (Chorto-haga virdifas-
ciata DeG.) continued to be the principal s-oecies involved.,
Melanoplus e :s gathered from the fields of Knox and Boyd
Counties on April 7 and 8 and placed under constant warm
temperatures started to hatch on April 18.

C. Benton (March): Grassho-onpers, mostly nymphs in various
instars, were observed daily in wheat fields near Fayette-
ville even during; a cold spell. Adults of the bird grass-
hopper (Schistocerca americana Drury) were observed in con-
siderable numbers in a wheat field near Howell, Lincoln Coun-
ty,on 'larch 29. :

L. Haseman (Anril 25): Eggs of the differential grassho-D-er,
M. differentialis Thos., two-striped grasshopper, M. bivitta-
tus Say, and red-lee !ed grasshopper, V. fcmur-rubrum-n DeG.
wintered well in western Missoiuri, but not so well in the
central -oart of the, State. Adult of C_, virdifasciata was
taken on April 23 at Columbia. Adults of S. anmcricni were
very common at Columbia April 22, probably mi-r.-nts.

J. M. Robinson (April 20): Grasshoppers are very abundant
at Brewton and Georgiana, they are eatinge: seeds off straw-
berri.es and causing the berries to shrivel, causing $500
da-nrge per day.

C. Lyle and assistants (April): With the exception of some
injury to strawberry plants by C. virdifasciata, grasshoppers
have been attracting but little attention throughout the
State during the month. (Abstract, J.A.H.)

R. R. Rerrert (April 4): Conditions in parts of Texas
have been f7av*.rable to successful overwinter/oT'grsshoppers.
Damage may be ex ected, -ossibly somew!.at heavier than last
season. Observations by this institution and by E. V. Walter
of the U. S. D. A. indicate that foci are in Presidio, El
Paso, Pecos, Uvalde, Medina, Tarrant, end X:iufman Counties.

A. G. Sterhens (April 18): Grasshoprors are moderately
abujndant over the northeastern section of the State.

G. M. List (April 20): Grasshoppers are very abunzdant in
parts of eastern Colorado.

G. F. Knowlton and M. J. Janes (April 19): F3gs have not
commenced hatching in northern Ut-'h. An examination of the
egg-laying grounds in the foothills west of Trenton showed
mortalities varying from 30 to 100 per cent, with a survival
of 70 per cent in the most favorable area. Beetle larvae
were feeding upon most of the egt" masses that vrero in good
condition.

J. R. icr (April 20): Nymphs and eggs of M. differentialis
are very abundant.


MORF'ON CRICKET (Anabrus simplex Hald.)

Z. P. Metcalf (April 22): Cutworms are more abundant in
tobacco in the eastern half of the State than they have been
for severr-l years.

W. H. Clarke (April 20): Cutworms are moderately abundant
in Thomnaston.

J. R. Watson (April 23): According to Prof. R. N. Lobdell
of the Evergltdes Exoeriment Station, cutworms entirely
stri-o-nei 100 acres of suarcane in the Everglades and did
much damage to other fields.

F. S. Chamberlin (April 12): Cutworms are quite abundant
in newly set tobacco in Gadsdon Count:.

D. Isely (April 23): Cutworms are scarce in Washington
County; lowest injury for several years.

H. C. Severin (April 20): Little damage has been reported
as yet, but cutworms are fairly abuzid-nt.

M. H. Swen'- (March 20 to April 20): From April 9 to 20
many farmers in a large area in east-central Nebraska reported
that serious danace was beinr done to alfalfa by the dark-
sided cutworm (E'xon mcssnria Harr.) working on the crowns
of the plants, cutting off the young green shoots as fast as
they started. The older alfalfa fields were first affected,
the cutworms later moving into newer fields. Alfalfa was the
chief crop attacked, but the cutworms were also working free-
ly on sweet clover, :.nd in Platte County were injuring wheat

and rye, while in Hamilton County they moved into barley
fields after strip-oping the alfalfa plants.' Lettuce and other
garden truck were also destroyed in some -olaces. The area in-
fested, as so far reported, extends across the State from
Knox, Antelope, and Pierce Counties on the north to Webster
and Thayer Counties in the South. Those cutworms that hatched
last fall or very early this spring have already made consid-
erable growth. The recently hatched ones are still very small.
These cutworms are active in the day time in some localities
where they are especially abundant, and have been reported
repeatedly as migrating in large numbers from field to field,
sometimes across roads, but not in the large solid masses of
worms, as in the true armyworm. According to our previous
notes on this species, these cutworms will not stop feeding
and enter the soil for pupating until well into May, and it
will probably be the end of June or in July before all have
done this. This means a long period for the cutworms to
work on the corn; and if -arasites do not destroy this abund-
ance of cutworms within the next few weeks, there will be
considerable danger to the corn from this outbreak.

L. Haseman (April 25): April 24 moths of greasy cutvorms,
Aarotis ypsilon Rott., on wing. Cutworms abundant at Columbia.

H. R. Bryson (April 22): Cutworms are moderately abundant
on alfalfa, garden crops, and strawberries. Reports of dam-
age have been received from scattered localities in central
Kansas.

C. Lyle and assistants (April): The usual reports of cut-
worm damage, particularly to garden truck, were received dur-
ing the month. (Abstract, J.A.H.)

C. F. Stiles (April 21): Cutworms are being reported in
fairly large numbers from practically all parts of the State.
Some alfalfa fields are infested with the variegated cutworm
(Lycophotia margaritosa saucia Hbn.) and the pale western
cutworm (Porosagrotis orthogonia Morr.) in Texas County.

J. H. Pepper (April 21): The army cutworm (Chorizagrotis
auxiliaris Grote) has been recorded in outbreak numbers. The
damage is not general, but has been recorded in scattered
fields throughout Missoula,Fergus, Yellowstone, and Powder
River Counties.

G. F. Knowlton (April 24): Cutworms are reported seriously
retarding the growth of alfalfa in parts of Millard County.

G. G. Schweis (April 20): Cutworms are very abundant and
doing considerable damage to alfalfa at Fallon and Reno.

J. R. Eyer (April 20): L. margaritosa saucia is very abund-
ant all over the State.

ARMrOR0 (Cirphis uni-runcta Haw.)


New Mexico


Florida


J. R. Eyer (April 20): This insect is very abundant all
over the State.

SALT-MARSH CATERPILLAR (Estignene acraea Drury)

J. R. Watson (April 22): This insect has been very ab-nd-
ant on a large variety of weeds; and F. W. Walker reports
that it has destroyed, or badly dam-naged, a great many fields
of watermelons and corn in northern Florida, all the way from
Gainesville to Monticello and as far west as Crawfordville in
!VU;axlla igunty. I never saw this est so abundant before.
Hasun ubtedly done dam-nage to the extent of many thousands
of dollars.


WHITE GRUBS (Phylloohaga spp.)


Georgia


Mi ssi ssippi



Wisconsin


Alabama












Mississippi






Utah


J. B. Gill (April 25): Reports of damage by May beetles to
pecan buds and foliare are being received from scattered lo-
calities throughout the State.

C. Lyle and assistants (April): May beetles started to ap-
pear by the middle of the month and were reported from several
sections damagin- the foliage of pecans. (Abstract, J.A.H.)

C. L. Fluke (April 25): Beetles of brood A of white grubs
are moderately abundant in central and northern Wisconsin.

WIRI0ORMS (Elateridae)

K. L. Coci-erha-. (April 6): On April 5, adult click beetles
(Heteroderes la".'rntii Guer.) were taken from field hibernat-
ing cares at Foley and it was found that about one-third have
successfully inassed the winter as adults. This is the high-
est percentage to come through the winter in hibernation
c. ,s that we have .yet found during several years' investiga-
tion. A very interesting thing with this species was that
on April 5 and 6, when larvae were removed from hibernating
ca,-es, 13 per cent were found to have already pupated. At
the sam-e time, di,-.ings and soil siftints showed the presence
of pupae in the fields. This is about three weeks to one
month earlier than the first pupation of previous springs.

K. L. Cock'crham (April 12): On April 12 the first newly
emerged adult of H. laurentii was found in the field at
Biloxi and on this date the first adult emerged in the lab-
oratory. This emergence is three weeks to a month earlier
than us:ial. On the same date larvae were found attacking
young corn very freely.

G. F. Knowltnn (April 18): Wireworms are reported in
northern Ut:dh.

F. H. 7?y7nore (March 29):,' Wireworms are moderately abundant
*at Chico and are seriously damagin- potatoes.

A. E. Michelbacher (April 19): Wireworms (Anchastus cinerei-
pennis Esch.) are doing some da-nge near Rio Vista. In some
sugar-beet fields they have reduced the crop about 5 per cent.
The larvae are quite numerous, but are not. doing so much dam-
age this year as last. In a portion of one field 300 larvae
were gathered in 57 minutes on the 25th of March. The larvae
were easily spotted by examining the soil around the wilted
young seedling beets.

RED SPIDER (Tetranychus telarius L.)

'7. A. Thomas (April 11): Red* spiders are doing considerable
damage to strawberries in the Chadbourn area. They are caus-
ing some of the bearing plants to die and seriously we-J:enini
others.

C. Lyle and assistants (April): Rather heavy infestations
of red spiders on evergreens and other ornamentals have been
reported from a number of places in the State. These infesta-
tions seem to be associated with continued dry weather. (Ab-
stract, J.A.H.)

E. J. Newcomer (March 30): Hibernating mites are numerous
in orchards at Yakima that were badly infested last year. Of
1,140 mites found under bark just below the ground, 475, or
42 per cent, were dead. Only about 2 per cent of the mites
hibernating in codling moth bands above the snow line sur-
vived.




CEREAL AND FORAGE-CROP INSECTS

WHEAT

HESSIAN FLY (Phytophaga destructor Say)

T. H. Parks (April 27): An examination of puparia taken
April 11 from an early-sowv wheat field in Pickaway County
showed heavy parasitism. A very few eggs were present then.
An examination of wheat -olsnts taken April 23 from the same
field showed very few eg.s present and no flaxseeds were lo-
cated. An examination of a Franklin County field on April
25 showed no eggs present. This field was sown early last
fall and 42 per cent of the plants were infested in November.
Hessian fly is apparently not making any headway in central
Ohio and egrs are difficult to find.

C. M. Packard (March): Considerable pupatlon took place in
early and late March at Lafayette. High mortality of the early
March pup ae occurred owing to cold weather March 7-24. No
emergence of adults.

J. H. Bigger (April): Examinations on April 19 indicated 90
per cent survival in Tvest-central Illinois. Approximately
75-80 per cent pupation has occurred at this time. Some emcr-x
ence has taken place. Eggs are moderately abundant.

C. Benton (March): Pupation increased gradually at Payette-
ville until by March 26 about half the nuparia contained pu-
pae. There was slight emergence of adults and oviposition
on March 1-5 and 24-30. First small larvae were found March
20. A few half-grovn larvae were present March 25-30.

L. Haseman (April 25): The Hessian fly situation is serious.
Adults were observed ovipositing in Sedalia April 16. Some
young larvae observed in leaf sheaths at Columnbia. Practical-
ly all flaxseeds contained pupae April 1.

M. H. Swenk (March 20 to April 20): During the period here
covered additional instances of heavy infestation of winter
wheat fields came to our attention, all of them, however,
within the area of infestation outlined in my report for the las
issue of the Insect Pest Survey Bulletin.

CHIN;CH BUG (Blissus leucopterus Say)

W. P. Flint (April): There have been scattered and rather
light flights of chinch bugs on several of the warm days this
spring, although there are still mnny bugs in hibernation. A
light Ilight occurred on April 2, which was probably the
first one this year.

J. H. Bigcr (March 26): All central counties expect severe
damage from chinch bugs in 1932. Some damage is likely to
occur in all counties from a line extending from Rock Island
to Kank-akee on the north to Murnhysboro and Carbondale on the
south. (April): The chinch bug is very abundant. A flight
occurred April 4.

C. H. Alden (April 18): The codling moth was reported
at Cornelia. 125 moths were caught in 15 bait traps on
April 19. No egg deposition has been observed to/date.

T. H. Parks (April 27): Codling moth is moderately
abundant in most orchards with a few orchards having very
heavy infestations. Collections of overwintering larvae
showed that less than 2 per cent of the worms had pupated
April 15. Packing houses contain fewer larvae than last
spring.

J. J. Davis (April 26): The codling moth has wintered
over in rather large numbers; and we can anticipate an
abundance of apple worms this season. At Bedford 3 per
cent had pupated April 23 while 9 per cent had pupated at
Lafayette.

L. Haseman (April 25): The first codling moths were seen
in southeastern Missouri April 19. About 20 per cent of
the larvae pupated at Columbia April 19; about 10 per cent
pupated at Aurora in southwest Missouri April 20. The
situation is threatening.

D. B. Thelan (March 20 to April 20): Overwintered larvae
first pupated on April 18.

5. F. Kr.nowlton (April 18): Codling moth survival is
rather low in the Lo.an area, as indicated by counts made

E. J. Ne.vcomcr (March 30): Examination of 5,692 larvae
collected during March from burlap bands that -ere above the
snow line during; the winter showed only 39 dead, or 0.7 per

and there were practically no large fluctuations in tempera-
turc. Puuation was just beginning March 25. Since infesta-
tion -.7as greater last fall thsn it has ever been, there will
be a big infestation this year unless unfavorable weather
during Mny and June prevents normal oviposition. (April 22):
Of 500 larvae examined, 23 per cent had pupated.

A. I. Bourne (April 25): Apple plant lice were hatching on
Apri17? Pji. out in numbers by the 20th. *At that time most
of the fruit buds were in the silver stage, only the most
advanced showing any evidence of color.

M. P. Zappe (April 22): Aphi pomi DeG. has hatched but
is very scarce and hard to find.

C. R. Crosby (April 25): Fruit aphids are just beginning
to hatch.

IT. Y. State Coll. A-r., Weekly ITews Letter (April): By
the middle of the month apple aphids were becoming numerous
in the eastern part of the Stqte. Though less abur.dapnt than
the apple grain anhid (Rh oalosi1Thum nrunifoliae Fitch) the
rosy apple aphid (An'-raghis roseus Baker) was being reported
during the first half of the month in the eastern half of the
State and was increasing rapidly by the middle of the month
in both the eastern and western fruit areas. The apple grain
aphid was observed in the lower Hudson River Valley during
the first week in Arril. By the second week in the month
hatching was quite -eneral throu-.hout the entire Hudson River
Valley and by the third week in the month, it was being quite
encrally reported throughout the western part of the Strte.
(Abstract, J.A.H.)

J. R. Stear (April 21): Apple aphids have been hatching
since April 5. !:_ny were killed by the cold weather during
April.

T. L. Guyton (April 21): The grain and the rosy aphids
are moderately abuMnd_3nt.

L. A. Sterr.s (April 21): Fruit -,ohids are moderately
abundant throughout the State.

W. J. Schocne (April 23): Rosy aphid e-->s were observed
hatcliin. in Auusctn County on April 4. They seem to be
present in very small numbers. They were reported present
in the northern part of the State around April 15, but are
not sufficiently numerous to be injurious. The present indi-

SAN JOSE SCALE (.,spidiotus perniciosus Comst.)


Massachusetts






New York


Pennsylvania


A. I. Bourne (April 25): We have had some reports of the
appearance of the San Jose scale in occasional orchards over
the State. The scale has apparently built up gradually in
those orchards which have been favored by freedom from Euro-
pean red mite infestation, and consequently the growers in
those orchards neglected to make any dormant applications.

N. Y. State Coll. of Agr., TTee The San Jose scale is. so plentiful in Ulster County that
most growers are applying special treatments for its control.
It was also reported as very abundant in Orange, Erie,
Ontario, and Yates Counties. (Abstract, J...H.)

C. R. Crosby (Aoril 25): Th'e San Jose scale is much more
abundant than in several years.

P. J. Parrott Aprill) : The San Jose scale is very abun-
dant in western New York.

T. L. Guyvton (April 21): The San Jose scale is very abun-
dant. About 10 per cent living scale on- trees in Franl-din
County in unspr'y-.ed orchards.

J. R. Stear (April 21): The San Jose scale has had a
heavy mortality in at least one apple orchard in Ligonier.
Counts of 3,863 sc4les made February 11 showed 42 per cent
dead. Of 531 scales examined Aipril 8, 88 per cent were dead.
This is probably due to sub-zero weather for a few days in
Ma.rch.

E. J. Newcomer' ((March 30): Of 700 bugs hibernating under
leaves in an outdoor cage, only 26, or 3.7 per cent, survived.
These were covered with snow most of the winter and the tem-

PLUT CURCULIO (Conotrachelus nenuo-.-r Hbst.)


Delaware

Georgia


L. A. Stearns (Aoril 21): The first curculio emerged from
hibernation on April 20.

7. J. Schoene (April 23): Tvo adults were tz2ken on April
6 near Grecn.Tood, but subseauent jarring in that section and
in .Augusta Count- failed to sho" the -nresence of the plum
curculio during the next ten da-rs. Adults were taken in the
Roanoke district on April 21; and were found in Blncksburg on
April 23.

0. I. Snarop (April 5): The first adult of the season vas
captured tod-y after jarring many -oeach trees adjo ining Yood-
lands at Fort Valley. Less than 5 oper cent of the buds have
opened on the first-blooming variety of peach. The other
varieties are still dormant. The curculios begin to aOpear
from hibernation ;,hen the first buds ocn. They are very
late leaving: hibernation this year. Likewise the peach trees
are blooming much l.-ter than usual. This is the latest ap-
pearance of adults front hibernation in 12 years of records,
and ordinarily '.e gould predict only one generation ; hoe;.ever,
since the each trcs "re correspondingly late bloor'iing this
Yrcar, we have no certain basis for a prediction as to the
number of broods of larvae to expect. (April 7): Adults are
beginning to leave hibernation in numbers. As m-nany as 10
were captured from a single tree in the first row of a peach
orchard adjoining: woodland. They have not yet passed the
second rov of those orchards which are -oartly in bloom. Some
orchards are still dor-iant and in these the adults have not
yet ap-ocneared. (Anril 20): The aorc-arance of adults from hi-
bernation has been light to date, and indications -ooint to a
light source of infestation for the 1932 season. Although
some varieties of peaches are in full bloom and the weather
sufficiently warm to cause c-icrgcnce from hibernation, very







-9C-

few adults have been captured in most of the orchards. A light
source of infestation has been anticipated on account of the
li*ht infestation in 1931 and the probability of -.ortality
from weather conditions during : the hibernation season. (April
25): A larva about three days old was found in a small green
peach toda.. A number of eggs were also found in little
peaches. Evidently so-e ovieosition has tak-en nlace during
the last 10 days or 2 weeks.

C. H. Alden (April 18): The plum curculio is scarce at Cor-
nelia. First adults were caught on jarring frames Arril 9.

7. H. Clarke (April 18): The first curculios of the season
were cau-ht by jarring this morning April 4; two speci-nons
were submitted by a Thomnaston grower "'ho estimated that 200
trees were jarred. Exoeri-nental jarring this morning, April 5,
showed only 6 curculios caught in three hours of jarring.
The first spring em-iergence of overwintering curculios is 19
days later t'.-n in 1930 and 11 days later than in 1931.
Jarring records shov a steady increase in numbers of beetles
emerging. Fcedin' injury has been found in the orchards,
but no eggs have been found. Matinr, has been observed in in-
sectary cages every day since April 8.

W. J. Reid, jr. (April 25): The diamond-back moth has
continued to be a very serious pest of cabbage in the
Charlest-on area. Breeding of the insect contin'L.el unchecked
during the entire winter. The pest attacked the spring cabbage
crop as soon as it was set in the field. At first the in-
festations of the spring crop were located near winter
cruciferous plantirr.s. At the present, approximately one-half
of the spring cabb%;e crop has been harvested. The worms are
now present in enormous numbers on the cabbage; all stFeos of
the insect are present in the field. The worms have tunneled
throu'th as rnany as six leaves of the cabbage heads; 90 per cent
of the cabbage plantings visited by the writer show an infes-
tation. The damage is severe in 75 per cent of the plantings.
