PEST SURVEY


Vol. 16 October 1, 1936 No. 9



THE MOIKE IMPORTANT RECOT DS FOR SEPTEoEER 1935

Grasshoppers were dying off rapidly during the last week of September.
A heavy oviposition was observed over most of the territory infested.

The fall arnyworm occurred in outbreak nurbers from Virginia and Tennes-
see southward to the Gulf.

The wheat midge in the Pvuyallup Valley of W.-shington has been found as far
south as Puyallup, nearly 50 miles south of any previously known infested
territory. In the older infested territory as high as 50 percent of the wheat
kernels were destroyed.

'i7heat stem sawflies have been al'undant this season in the Middle Atlantic
and East Central States, the infestation in Ohio being especially heavy.

Corn ear worm, which has been unusually scarce thrnughnut the season,
developed rapidly during September from Iew England and Iowa to Norrth Carolina
and Tennessee. Late corn and tomatoes were seriously damaged in many sections.
This insect was also reported as doing commercial dar-e to tomatoes in Cali-
fornia and Mississippi, and to lima beans in North Carolina.

European corn borer has been found for the first time in Norfolk and
Princess Anne Counties, on the mainland of Virginia.

Chinch bug was moving into winter quarters during the last 2 weeks of
September.

Alfalfa caterpillar was reported seriously damaging sweetpotatoes in
Tennessee and doing heavy damage to alfalfa in Colorado and California.

The cotton leaf worm moths were reported as seriously damn.ing late peaches
in Missouri and flights of this insect were reported from Connecticut.

Heavy late boll weevil infestati-ns were reported along the Atlantic sea-
board and considerable danage was being done in late fields.

Defoliation of cotton by leaf worm was quite general throughout the Cotton
Belt. Late cotton also suffered from bollw7orn depredations.

A serious outbreak of the eastern spruce beetle was reported from the
Green Mountain National Forest in Vermont. Over 90 percent of the merchantable
spruce in limited areas has been killed.

GENERAL F E E D E R S

GRASSHOPPERS (Acrididae)

Indiana. C. M. Packard and associates (September 18): Adultsof Melanplus
mexicanus Sauss., M. differentialis Thos., and M. femur-rubrrum re,. are
from common to abundant everywhere around Lafayette. While working in
experimental plots and wheat stubble fields noted some eggs in soil.
E -s have been unusually noticeable on automobiles, where hoppers have
smashed against them.

Illinois. W. P. Flint (September 24): Ez: laying has been general for about
3 weeks and is still going on. 'Weather conditions have been very favor-
able for the hoppers during the egg-laying period. Hcpers are now
dying very rapidly, especially the differential grasshopper.

Missouri. L. Haseman (September 25): Grasshoppers have been ovipositing
now for some time in central Missouri but the peak of e6g laying has not
been reached. Adults are much less abundant over most of the State than
during the summer, but indications are that a good supply of eggs is
being deposited. Hoppers are damaging the margins of alfalfa and fall-
seeded small grains. About half of the grasshoppers at this season
are M. differontialis, the other half being about equal numbers of M.
femur-rubrum and M. mexicanus.

Tennmessoe. G. M. Bentley (September 2): J. C. Moser reports large numbers
of ,.; femur-rubrum in pastures in western Tennessee.

Alab,-Ima. J. M. Robinson (September 25): Adult grasshoppers are attracting
attention at 3essemer.

Mississippi. C. Lyle (September 24): Grasshoppers eore strippi.nz about 200
acres of soybeans at Cruger on September 14. Apparently most of the
!>'mar was being done by M. mexicanus. Dissosteira carolina L., M.
differentialis, and M. femur-rubrum were also collected.

Nebraska. M. H. Swenk (September 23): A delayed late-Augiust and September
hatch of grasshoppers, principally of the two-striped grasc-h !er (M.
bivittatus Say), has caused some apprehension among farmers in CasF,
Saunders, Gage, York, ":.cknlls, and adjacent counties.

Okn.oma. C. F. Stiles (September 25): M. differentialis still quite numorcus
along creeks and fence rows and in some parts of the State is da, goingg
alfalfa. I.i st of the other species numerous earlier in the season have
died.

Color i.-. S. C. ":cCampbell (September 21): J. R. Parker and R. L. Shotwell
were '.ith me last week investigating a heavy infestation of r'isteirn
':.ij : _. Those. (comonly mnown as the long-wingLd locust of th,:
plins), involving 100 square miles of southeastern Colorado. Part of
this area is heavily infest.,d with --, as many as ,':00 .-r square
foo(t havir:- been estimated in some parts of the fields.

:,ORMO 1CRICKEIT (Anabrus simplex Hald.)

Nevada. D. F. Barnes (July 2g): While driving west through Nevada cn July
18, I crossed a heavy infestation of Mormon crickets extending from
about 10 miles east to about 10 miles west of Elko. On the west side
of Elko control work was being carried on. At one point where the
barriers had been removed there was a strip of dead crickets from 14
to 16 inches wide and several miles lon--. The infestation at Emigrant
Pass between Carlin and Dunphy was lighter than in the latter part of
May, but individuals were still crossing thc road. The infestations
constituted a motor hazard.

G. G. 8chweis (September l14): Specimens of a wasp found attacking
Mormon crickets in eastern Nevada were identified by G. A. Sandhouse
as Chlorion laevivontris Cress.

FIELD CRICKET (Gryllus assimilis F.)

Iowa. H. E. Jaques (September 23): Carroll County reports moderately heavy
losses from black crickets.

Texas. 0. G. Babcock (September 20): Black crickets following heavy rains
were very numerous at Austin about the business buildings at night,
wherever the store lights were on. They were so numerous they could be
swept up into piles and scooped up. The sidewalks wore covered at night.
A few were a'out at Sonora.

EURTPFEAIT EARWIG (Forficula auricularia L.)

New York. E. P. Felt (September 25): The European earwig was found to be
well established at Roslyn, L. I., on September 9.

CUTWOR!iS (Noctuidae)

Tennessee. E. W. Howe (September): Th'-ere has been a serious outbreak of
several species of cutworms at Clarksville during August. Tobacco and
corn on low ground, which had remained comparatively damp during the
drought, were seriously infested.. Apparently the moths flew to the
greenest herbage available and laid their 3-s. One tobacco field
suffered a 50-percent loss in stand. Two areas in large cornfields
suffered a loss of about 65 percent, but over the entire acreage involved,
the loss was not over 6 percent. Most damage occurred prior to September
15, but some corn was damaged at the end of the month. In attacking
corn the larvae first defoliated crabgrass and other low vegetation,
then climb-d the cornstalks, fed on the leaves (frequently leaving only
the midribs), and ate the silk prior to fertilization.

FALL ARMYWORM (Laphygma frugiperda S. & A.)

Virginia. H. G. Walker (September 25): A very heavy outbreak of the fall
armyworm occurred between July 20 and August 1, when it completely
destroyed nearly all of the millet and Sudan-grass fields and injured









some cornfields in the Norfolk district. From August 15 to 31 they have
beoon present and have done considerable damage in late-planted corn.

i'orth Carolina. C. H. Brannon (September 10): D-umage to corn reported :v:r
a wide area.

Georgia. T. L. Bissell (August 28): The fall arm..,":'.'rm is very abundant on
grass at Experiment. (September 2): ThD fall armi,':orm is ruining a large
field of corn at the Experiment station. (September 10): Holes are
being eaten in pimiento pepper fruit at Vn.-hn. (Sept-..-nber l14): A
st .'r was made of injury by fall ar-:mvorm and corn ear worm (Heli, this
obsoleta F.) in late field corn at Experiment. Of 435 ears, 421 were
infested. In these ears were found 337 fall ar-y-'orms and 157 corn -ar
worms. It w"as estimated that 39.2 percent of the grain had been ruined,
though the injury to the crop was greater because many ears failed to
develop.

G. F. i, oznette (September 15): Thc fall armyworm has been quite
prevalent in southern Georgia in fields of cotton, kudzu, and Johnson
grass, and has caused considerable damage.

Florida. J. R. Watson (September 24): A few complaints have been -receivc!
of the depredations of the fall arm-.',rm, although it is not as numerous
as it has been in other years.

Tennessee. G. M. Bentley (September 3): The grassworm has been dnnmaing corn
in Cheatham and Cannon Counties. (September 14): Lima beans at Tellico
Plains, i4onroc County, were also damaged. Estimated loss to the bean
crop vas $5,000.

Alabama. J. M. Robinson (September 25): During tho firet week in Septc-ibcr
the fall ar'i,-rorn was reported as active on 150 acres of soybeans to be
used for seed in Wilcox County.

M, ississippi. C. Lyle (September 24): Fall armyworm was causing serious injury
to a lawn at Meridian on August 28.

VELT'E EAIT CAT IILLAR (Anticarsia gemmatilis H-bn.)

South Carolina. F. F. Bondy (September 5): Grass worms and the soybean
worm, probably A. gemmatilis, are doing damage in parts of Darlington
County. (September 26): The southern grass worm and the soybean worm
are doing serious damage to soybeans, and farmers are inquiring about
control measures.

".:-I2B GRUBS (?hllT'ha. spp.)

Kentucky. W. A. Price (September 25): Digging records show that white ..rults
have been much reducci in numbers in the vicinity of Tcxinrton durin-
the past 2 months.

Minnesota. A. G. R.i-:-lcs and assistants (September): White .jrubs are very






-359-


abundant in Winona, Freeborn, and Mower Counties in southern Minnesota,
and in Crow Wing and Carlton Counties in east-central part of the
State.

GREET JUNE BEETLE (Cotinis nitida L.)

Virginia. H. G. Walker (September 25): Nearly full-gr. 'n grubs are moderately
abundant in some spinach fields at Norfolk, where they have caused a small
amount of damage by burrowing under and killin!- the young spinach.

ASIATIC GARDEN BEETLE (Autoserica castanea Arrow)

Connecticut. E. P. Felt (September 23): Grubs caused appreciable injury to
snapdragon plants in a Stanford greenhouse, the soil in which the plants
were growing having been brought in recently.

A WEEVIL (Laupatuctus leucoloma Boh.)

Florida and Alabama. J. R. Watson (September 24): A weevil new to North
America, identified by L. L. Buchanan as N. leucolona, appeared this
sunnmmer in the northern part of Walton County, Fla., and adjacent areas
of Alabama. According to the county a:rt, it did much damage to
peanuts and some to cotton and other plants.


CEREAL AND FORAGE-CROP INSECTS

1t7EAT

]ESSIAN FLY (Phytophaga destructor Say)

Ohio. T. H. Parks (September 26): An examination of volunteer and early
sown wheat on September 21 showed few eggs present. As very few of the
aestivating insects remain alive, we do not expect any serious injury
this fall, even to the early sown wheat.

Indiana. C. M. Packard and associates (September 18): Dissections of wes-
tern-Indiana material indicate summer survival of puparia in stubble
to be from 1 to 20 percent, depending upon local conditions. Consider-
able pupation now in prn.-resos. The mid-August rains sprouted much
volunteer wheat in the vicinity of Lafayette and caused some fly emergence.
A few egns noted September 8 on volunteer, some already hatched. In
two fields seen yesterday near Delphi, much of the volunteer was already
showing infestation, mainly from small to mature larvae, with a few new
puparia.

Illinois. W. P. Flint (September 24): Early fall rains have caused emergence
of adults and a growth of volunteer wheat. This will, on the whole,
be favorable to the sowing of a commercial wheat crop, as most of the
flies will be out before the normal date of seeding.

Missouri. L. Haseman (September 25): We will have considerable early seeded
wheat and in most sections of the State we are finding sufficient live








-3 o-
flaxsocds to cause serious c ncern. A crnsiderable number of the
flaxseeds in central Missouri are showing parasitization and a great
L'nr.r oth. rs w!ore probably destroyed. by the heat.

NWbraska. M. H. Swenk (September 23): The hessian fly is at such a low
ebb of population that no observations are being made of the safe-
sowing date.

BLACK GRAIN SKE;.. SAWFLY (Trachelus tabidus F.)
EUROPEAN WHEAT STE7: SA',AFLY (C-_hu pyg -naeus L.)

General. J. S. Houser, E. J. Udino, and J. S. Pinckney (August): Surveys
made this suimor for wheat stem sawflies sho-wed T. tabidus more or less
abundant in wheat fields over a wide territory, including most of Penn-
sylvania, Maryland, Delaware, Virginia, and part of eastern Ohio. The
infestation was by far the heaviest in eastern Ohio, where it was
alarminglj abundant in several counties. In that State infestations have
advanced considerably farther westward since last year. Surveys in parts
of Virginia and North Carolina showed none south of Campbell County.
C. pygmaeus was present, as usual, in western n Neow : York and was increasi.c-
in eastern Pennsylvania.

c:- Fi.U

CORN EAR --RF-.! (Heliothis obsoleta F.)

M1assachusetts. A. I. Bourne (September 24): The corn ear worm has been much
less abundant than usual, and no complaints of severe damage have b received. A -'cry slight amount of it was noted in early maturing corn
in the vicinity of Springfield.

Connecticut. N. Turner (September 21): The second brood infested about 17
percent of the sweet corn at Mt. Carmel farm, about 6 percent loss than
in 1935. Small larvaeo are still present.

Indiana. E. V. Walter (September 1S): A heavy deposition of e,-:-s began at
Lafayette about August 26 and has continued to date. Nearly ev ry corn
ear is infested with from one to six larvae. y.L-se are in all st,-,es of
mat ur it y.

Illinois. W. P. Flint (September 24): Little infestation up to the first of
September. Since that time a rather heavy flight of moths has occurred
and in fields of late corn nearly 100 percent of the ears are infested.

Kentucky. W. A. Price (Septomb. r 25): Corn ear worms are unusually abundant
in late corn and tomatoes in the vicinities of l'._lbyville, Lexington,
and Elizabethtown. In several patches of latu corn the leaves, tassels,
and stalks are bein- riddled.

Iowa. H. E. Jaques (September 23): The corn ear worm is strongly contesting
with thu :,s "-.:p ... :rs for first place. The drought has made their daMnagc
a nri rous >iatt cr.









Missouri. L. Haseman (September 25): With practically all of the corn crop
being destroyed by the drought and very little forming even nubbins,
the corn car worm is less abundant than for many years. Some late green
tomatoes are being injured.

Tennessee. G. M. Bentley (September 3): Corn ear worm is attacking millet
and the pods of soybeans and cowpeas in Cannon County. Heavy injury to
corn in bottom lands in western Tennessee. Also reported da&mnaging sweet
corn in Sevier County at least 75 percent. In some cases practically
none of the corn can be used for canning.

EUROPEAN CORN BORER (Pyrausta nubilalis Hbn.)

Massachusetts. A. I. Bourne (September 24): The European corn borer has
caused rather less damage than usual, particularly in the eastern part
of the State where the infestation is of longer standing. This is
based on the number of damaged ears, rather than on stalk infestation.
There were instances of heavy infestation in market-garden areas in the
Connecticut Valley.

Connecticut. N. Turner (September 21): Second-generation infestation on
sweet corn at Mt. Carmel farm was about 20 percent less than last year.
About 30 percent of the ears are infested. Infestation in dahlias was
at least as heavy as in 1935. Untreated plants are entirely ruined.

Virginia. H. G. 'ahlker and L. D. Anderson (September 26): The European corn
borer has been found for the first time in several cornfields near the
Chesapeake Bay in Norfolk and Princess Anne Counties, but none was found
more than 5 miles inland.

CHINCH BUG (Blissus leucopterus Say)

Ohio. T. H. Parks (September 26): Some farmers in northern Ohio are report-
ing chinch bugs present in plentiful nra:cbrs on the -7mons as they fill
their silos. No serious damage was done to the corn.

Indiana. C. Benton (September 1): ;Mid-August surveys in standing corn
showed the following avera-e numbers of chinch bugs per stalk, by
counties: Benton, 27; Tippecanoe, 46; Clinton, 8; and Tipton, 3. In
Tippecanoe County second-brood bugs wore still abundant in corn on
September 17, being mainly from third instar to adult. They were also
abundant on young timothy in a wheat-stubblo field. Examinations of
bunch -rasses on September 17 showed some accumulation of adults in
hibernation quarters since September 1, when practically none were
present in bunch grasses.

Illinois. W. P. Flint (September 24): Chinch bug development was retarded
somewhat by the extremely hot weather early in August. Development was
normal during the latter part of August and first part of September.
There is a heavy infestation over all the west-central part of Illinois,
extending south below the latitude of St. Louis, Mo. The infestation
is lighter in the eastern part of the State. Large numbers of bugs have










been flying to winter quart-rs, since about September 10.

Missouri. L. Hase.man (Septezber 25): The carry-over of chinch bugs seems to
be light, except in a few isolated localities, where farmers are rer.ort-
ing that they are abundant on late corn and sorghum.

Nebras:a. 74. H. Swenk (September 23): Chinch bugs *.,-re reported as present
in -ronter than normal numbers in the cornfields in Richardson and Nema-
ha Counties from August 20 to September 20.

DESERT CCT "I FLEA BEETLE (Chaetocncrn. ectypa Horn)

California. H. J. Ryan (September 10): Three acres of popcorn out of a
5-acre field were destroyed in Los An'elos County.

ALFALFA

ALFALFA CA.TERPILLR (Eur.'--uis eur.-thec7e Bdv.)

Tennessee. E. W. Howe (September): Alfalfa caterpillars seriously damar.ei
sweetpotato folia:-e at Clarksville during the latter part of the month.

Colorado. S. C. McCampbell (September 21): We have had an abundance of the
alfalfa caterpillar. In the lower Arkansas Valley during the past 30
days considerable injury has resulted to alfalfa.

Califor-ia. H. C. Donohoc and C. K. Fisher (August 27): Alfalfa fields in
Fresno County have been heavily infested with adults for several days.
Several fields have been noted within the last 2 days containing the
greatest adult infestations the writers have ever noted.

C. C. ".7ilson (September 4): The alfalfa caterpillar, -'hich
usually builds up to severe damaging proportions on the fourth and fifth
cuttings of alfalfa, has again destroyed 1,r -e acreages of hay in Sacra-
mento County. D-amage was severe on approximately l,0O0 acres, causing
a reduction of 1 ton per acre. The monetary loss over an area of 100
square miles was estimated to be approximately $15,000, while hay buyers
estimated 10 percent loss for the county. Bacterial wilt attacked the
larvae, but conditions favoring this disease came too late to avert the
the da'ma .e.










FRU I T INSECTS


SA1T JOSE SCALE (Aspidiotus perniciosus Comst.)

Georgia. 0. I. Snapp (September 14): Crawlers are now beginning to set up
on peach twins in numbers at Fort Valley. There were very few crawlers
on peach trees until Septcrber. The infestation usually builds up
rapidly on peach trees in Georgia durin- this month.

C. H. Alden (September 24): A 1liht, general infestation noted
throughout the peach- and apple-growing sections around Cornelia, but
few heavy infestations found.

APPLE

CODLIIT, '1OTH (Carpocapsa pomonella L.)

Virginia. W. J. Schoene (September 24): The third-brood codlin, moth has
Ien unusually large this year and has caused considerable injury in
orchards where an abbreviated schedule has been followed.

Georgia. C. H. Alden (September 24): Moth emergence about over; practically
none caught in the bait pots during the past 2 weeks. Larvae in apples
are about full fed and those leaving are spinning up winter cases. The
insect has been no more abundant this season than usual but appears to
be worse, because the State has less than one-third of a normal crop
of apples.

Ohio. T. H. Parks (September 26): Sixty-three commercial apple orchards,
located in all parts of the State, checked for insect and disease
blemishes during the latter half of Suptember, showed an average of 6
percent of the fruits carrying stings or entrances of larvae. The
orchards ranged from 69 percent worm injury to 0.01 percent. Only a few
orchards have a serious problem. The percentag-e of insect- and disease-
free fruit in these orchards averaged g9.l. :ost of the orchards in
the east side of the State received no spray for the second generation
of worms. .lany in Ottawa and Lawrence Counties received five cover
sprays.

Illinois. W. P. Flint (September 24)-: Codling moths are still hatching and
entering apples in small numbers. The infestation in southern Illinois
is one of the heaviest that ever occurred in that region. Many orchards
in western Illinois are also heavily infested. Apple picking is more
than half over in all the important orchard sections of the State. The
situation at present points to a very heavy carry-over of worms next year.

Minnesota. A. G. Rugles'and assistants (Augzust 29): Codling moth very
abundant in Free born County.

Missouri. L. Haseman (September 25): In southern Missouri late worms continued
to enter up to the middle of the nnmonth. In central Missruri the last
moths were taken in the bait traps on September 15. The carry-over of










"eors in Missouri will be lighter than for '.-'.' years past.


Washington. E. J. ':,'-rconer (September 22): Cool weather early in Soptearcer
prevented a heavy late emergence of ioths 'in the Yakima Valley; the
hi.-h point from August 12 to 18 was the peak. There are as a conscqu:nce
fewer late worms in the fruit.

BED-WT:YED CATR'RPILLAR (Schizura concinna S. & A.)

Iississippi. C. Lyle (September 24): A colr"-- of worms on apple foliage was
sent in fron Maglnolia on September 15.

APPLE LEAIH'FLRS (Cicadellidae)

Massachusetts. A. I. Bnurne (September 24): The late brood of the white
apple leafhopper, Ip.l1ocyba pornria McAtee, is not more than norrnally
a' Ul.-int; in comparatively fe!.w orchards has there been any serious
spottingj of the leaves or fruit.

Connecticut. P. Garman (September 22): Infestotion of -w:hite apple leaf--.'pper
is front moderate to heavy in New Haven County.

Vir-cinia. 77. J. Schoene (September 24): The white apple leafhopper is
ogenerally present in apple orchards and is causing nr-n-y'.nce to pic'Crs
and some loss due to the specking of the fruit.

Illinois. T7. P. Flint (September 24): Apple loafhoppers have been extremely
*'**n-nt in nearly all commercial orchards in westernr n and southern
Illinois.
Kentucky. W71. A. Price (September 25): Adult apple leafhoppers, principr.lly
Erythroneura cores naculata Gill., are present in rc-it numbers in
apple orchards in central Kentucky nn-r have caused considerable defolia-
tion.

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

Massachusetts. A. I. Bourne (September 24): T:-.. re is a very extensive
bronzin:- of folio, e in m'.'y of the larger apple orchards of the State
resultin: from late-season abundance of l'ir.-peoan red mite. During;: the
latter part of the sux-mer nore red mites were present -cnerally through-
out the orchards than for v-n: years.

F 1:A "1

CC:T:: L "I*R" (Alabama ,arill:c,:c Hbn.)

Miss uri. ',. F. Turner (Septembr- 25): One peach grower .n Scott County
has a considerable planting of Henrietta peaches, which are just -otting
ripe. Adults of the cotton catcri illar have r-,i.cd most of the fruit
by feodin, rn it. This grower states that he has the same ceq:'-rience
Cvrr 3 or 4 years and that he is pulling up the entire block this -r:r.







-365-


Hereafter, ho will grow nothing that ripens after Elbertas.

PEACH BORER (Conopia exitiosa Say)

Georgia. 0. I. Snapp (September 19): The peak of moth cor:-en.'-e occurred at
Fort Valley during the first week of September, which is earlier than
usual. This was expected on account of the unusually early pupation
season this year. Observations during the last month indicate that
infestntion was heavier than that of 1935.
C. H. Alden (September 24): Peach tree borer infestation is not
as heavy as in 1935 at Thomaston and Cornelia.

PEACH TWIG BORER (Anarsia lineatella Zell.)

California. D. F. Barnes (August 3): General reports indicate a rather heavy
infestation in peaches in Fresno County.

C'RIEI17CL FRUIT .IOTH (Grapholitha molesta Busck)

Connecticut. P. Garnan (September 22): Infestation of oriental fruit moth
is heavy in some orchards in New Haven County. Infestations in Elbortas
are estimated at from 30 to 50 percent. In other localities the infes-
tation has been light, not over 10 percent.

Ohio. T. H. Parks (September 23): This insect was much more injurious to
peaches along Lake Erie than for several years. The Elberta crop was
badly infested in some orchards.

Tennessee. G. M. Bentley (September 3): Fruit moth injury loss on peaches
than usual in western Tennessee as reported by J. C. Moser.

PLTIJT CURCULIO (Conotrachelus nenuphar Hbst.)

Georgia. 0. I. Snapp (September 10): Second-generation adults are now
onemerging in numbers in Elberta peach orchards at Fort Valley. There
are no adults on the trees of varieties that matured fruit before the
deposition of second-generation eggs. First-generation adults have not
been found on peach trees during the last month.

Tennessee. G. M. Bentley (September 3): Curculio injury less on peaches
this year than usual in western Tennessee (J. C. Moser).

GRAPE

GRAPE BERRY MOTH (Polychrosis viteana Clem.)

Ohio. T. H. Parks (September 23): The grape berry moth is quite serious in
commercial vineyards of Columbiana County. Some growers will have
from 25 to 30 percent loss of their Concord grapes.

PZCA.IT

4ILmUT CA.-R7ILLAR (Datana inte~errina G. & R.)

Geor:ia. G. F. Moznetto (Septeober 15): "Jalnut caterpillar has bocn unusually
abudant in pecan orchards at Albany during Au ust and Septcnber and
hrs caused considerable dana, e. In snoe instances the folia strirppe.d from pecan treocs, but noro -cnerally individual lar-ce branches
have beon stripped.

Mississipci. L. J. Goadrsae (Septenbcr 24): A fe ',.U'L pecan trees in
Pontotoc C-unty mere bein,-: defoliated on September 19.

PIC.I LEAF CA'SZL'iLR (Acrobasis j umqlandis LoB.)

Geonra. G. F. Mnznt-te (Septenber 15): The sumner cases of pecan leaf caso-
bearer vwere n-t as abundant at A-i"J.. as f-r the sameI period last season,
which wnuld aqpn.rently indicate that in this vicinity this insect will
not cause a <-'reat deal of dar.a-. next sprinr-.

PZ7.'7i ITU C..SEL:~.R (Acrobasis ctvryac Grote)

Geor'ia. G. F. Mznetto (Septenber 15): The third-generation larvae are now
feeding on the shucks of pecans at Al -Iar:, and are more readily found

CITRUS WHITEFLIES (Dialeurodes spp.)

Florida. J. R. Watson (September 24): Thc: infestation of whiteflies in most
of the citrus is the heaviest in many years. i.Ianny roves are pretty
thoroughly blackened. The cloudy-winr-ed whitefly (D. citrifolii Morg.)

of the Citrus Belt it has now become the dominant species where D.
citri Ashm. was formerly the chief form.

Mississippi. C. Lyle and assistants (September 24): Heavy infestations of
whiteflies have been observed alon:-; the coast on satsuna orang-es and

never developed squash because the beetles were so n-nierus.

SPOTTED CUCU.EER BETLE (Diabrotica duodccin-unctata F.)

Missrouri. L. Ease-ian (September 25): Fr-.m September 1 to about the 20th
late squashes and cucumbers were nore heavily infested with b-th

Mississippi. C. Lyle (September 24): Serious injury to fall tomatoes was
reported at Poplarville by J. E. Lee and at Jackson by Jack Milton.

";'ashin-rton. R. S. Lehman (September 28): The corn ear worn, which did ex-
tensive d.-w',-e to sweet corn at Walla Walla earlier in the season, has
been very destructive to tomatoes. Fields of tomatoes nearest to sweet
corn have shown greater dar-a.e than others. One field was noted that
had no marketable tomatoes.

California. A. E. Michelbacher (September 24): An examination of the tomato
fields in Sacrw--ento and Yolo Counties on Aucust 30 and 31 showed only a
little fruit infested. With a single exception, the infestation was
less than 4 percent. In one field at Sacramento 6 percent of the ripe
fruit was infested, while about 20 percent of the small green fruit c-n-
tained worms. In the tomato-growing district about Brentwnod the in-
festation on tomnatoes has remained liLht. There is some indication
that the infestation is going. t- build up. In several fields examined
from 4 to 6 percent of the small greon fruit was infested. The only
area where the corn ear worm has been very destructive is in the San
Francisco Bay district. Some fields have had as much as 20 percent of
the fruit dan-ingod, but the general avera,,e is much below this, usually
being less than 10 percent.

v!ere found on rape and turnips.

CABBAGE LOOPER (Autographa brassicae Riley)

Connecticut. N. Turner (September 21): Cabbage looper sli }htly less abundant
than usual this year in southern Connecticut.

Virginia. H. G. Walker (September 25): The cabo P:e looper was beccm..ing
rather abundant in many cab>7ge and collard fields in the Norfolk area;
however, since the hurricane and the 4-inch rain accompanying it on
September 1i, many of the loopers died from a bacterial disease.

BEE:T LEAFHOPPZR (Eutettix tonelius Dak.)

Colorado. 0. A. Hills (September 22): The sugar beet crop in the beet-gro-ving
sections of the western slope of Colorado is considerably above average
this year. Large, vigorous beets are found generally in the Grand Valley,
Delta-Montrose, and Rifle districts. This favorable condition of sugar
beets is partly duc to the low populations of beet leafhopper, which dis-
persed into these districts in April and May.

Utah. G. F. Know-lton (September 2): Moderate damage to beets has occurred
in places near the local breeding areas.

YELLOW WOOLLY BEAR (Piacrisia virginica F.)

a groat deal of da -nc in a co:Tiercial -iushroonm house mnar Tou-hkenamon,
Ch.ster County. The mites ar3 so numerous that t}l.:-. look like brown
powder on the caps of the -ushrooms., They che'w the feeder ro-ts, causi:-..-
the nmushrorrms to die, and also eat holes in the cnrs. A house near
Oxford, Chester County, has been reported to be similarly infested.


COTTON I N S E C TS

BOLL VVLEVIL (Anthonomus grandis Boh.)

North Carolina. C. H. Bran-on (September 25): L.:o;: sections of the State show
heavy weevil infestation; other sections are lightly infested.

Sruth Carolina. F. F. Bondy (September 5): :.; late cott-n at Florence that
has not been poisoned is now overrun with weevils. The poisoned cotton
is still in full bloom. (Septemb-r 2): Cotton is taking a second
.ro-'th and weevils are increasing, but the nunbor in the fields is still
bel'.7 normal.

G-eor:-io. T. L. Bissell (Septeobpt r 9): The boll weevil is numerous on cotton
ot Lxpriment.

P. MI. Gilm r (Soptember 5): At Tifton the infestation has contilnu-'d
t, increase slowly in Upland cotton. In Sea Island cotton practically
1'r p:.rcent of the squares are now attacked in the ur ison h. fields.
".er squri',-- is still in progress a majorityy of the squares are no'w
attacked and injury in unlp-isoned fields is boc...inn- rather serious.
It is doubtful otherhr tany of the un-p.-n bolls rill mature. (Scpte-bjr

h rd f or se.n ary bE,, 1 oevil in Tennos ee this yeor.








-377-


Alabama. J. M. Robinson (September 25): The boll weevil infestation at
Auburn did not become sufficiently high to require dusting the cotton.
In southern Alabama, particularly in the southwestern part, some dusting
was necessary.

Mississippi. C. Lyle (September 24): The boll weevil infestation in the
State is very light. In some sections in the central part of the State
the weevils were numerous enough to puncture practically all of the
late squares, but this condition was not general and practically no
damage has been done.

E. W. Dunnam (September 5): In Washington County a few weevils
can be found in green spots where there is some fruit available, but the
population is almost negligible away from the wooded areas. :4igrati-n
has been very light.

Louisiana. R. C. Gaines (September 26): During the past 4 weeks there has
been a scarcity of squares and bolls at Tallulah for the late breeding
of the boll weevil, -wing to the stripping caused by the leaf worm
(Alabama argillacea Hbn.); however, some cotton that was stripped s'me
time ago is now taking on second growth, which may afford a considcra'ole
number of squares for late breeding.

Oklahoma. C. F. Stiles (September 25): Boll weevils have done loss damage
to cotton this year than at any time since they became generally estab-
lished in Oklahoma. One has to search carefully in the fields in the
east side of the State, where they are usually quite numerous, tr, find
adult weevils.

Texas. R. 7. Moreland (September 12): The weevil infestation record in late
cotton for the second brood at College Station is as follows: 3,00
squares examined in three experiments; the check plots ranged from 13.3
to 18.3 percent, with an average of in.7 percent; the treated plots
ranged from 0.3 to 13.3 percent, with an average of 4.2 percent; the
treated plot, with 13.3 percent infestation, had received only two appli-
cations of poison.

K. P. Ewing (September 5): At Port Lavaca weevils continue to daa.e
many fields. (September 12): There was a wide-spread migration of boll
weevils during this week. Observation of cotton fields in Calhoun and
Jackson Counties indicates that practically 100 percent of all squares
and bolls are being damaged, and even large bolls are being punctured.
The small late crop that was anticipated a few weeks ago is being reduced.

Mexico. C. S. Rude (September 5): At Tlahualilo the boll weevil infestation
in new squares is very heavy and the top crop is being damaged consider-
ably. (September 22): The crop from the Don Martin project is ginning
out about 50 percent as much as it has for the past 2 yearsr, notwithstand-
ing the increased acreage this year. The reduction is accounted for by
failure to control the boll weevil.

northh Carolina. C. H. Brannon (September 15): Heavy infestations in Nash,
Iredell, and Mecklenburg Counties reported. The list is -r:'.in;c ev.:ry
day. 1Iost of it is on very late cotton, makin01 the infestation very
serious. (September 18): Leaf worms are now reported from almost all
cotton sections of the State. 7c have a greot deal of late cotton,
which will no doubt be seriously danam-,'ed. (September 25): Late c-tton
in all parts rf the State is being attacked.

South Carolina. F. F. Bed-: (Seitember 5): At Florence cotton leaf worms
are increasing and are beinning to defoliate fields of youn.' cotton.
(September 19): Increasinr, very slowly. Parasites apparently have them
in check and no fields have been defoliated.

Geo r-ia. T. L. Bissell (Au-ust 31): Catr3rpillars o un:i-nt "n cotton at
Z_:-erinont Station. It was reported to mie today that worms 'ere seen
feeding< at Cedartowvin on "Auuvt 14. (September 9): The cotton leaf
'.orm is doinr considerable dama. e because, on account of dr- ht in the
early sumner, cotton is late.

Alabama. J. M. RIbinson (September 25): The cotton leaf worm appeared
generally over the State throughout the latter half of Au-ust and Septen-
ber. Th3 cotton was sufficiently advanced in southern and central Ala-

however, where the cotton vrwas late, considerable damag-e was -done and
a lot of dusting was necessary to hold this pest in check.

Mississippi. C. Lyle (September 24): The cotton leaf worm is generally dis-
tributed over Mississippi, but the amount of damage has been very light
on account of the early maturity of the cotton.

CATTLE

SCRC0.' Cj.I (Cochlionmyia americana C. & P.)

United States. '7. E. Dove (September 26): At present the low incidence of
screwworm cases in the Southeastern States permits curtailment of
control work of the Bureau in some areas and more intensive work in
southern Georgia and Florida. From June 5 to SepDtember 18 there were
16,187 reported cases of myiasis in Alabama, Florida, Georgia, Louisiana,
Missisgipp-i, and South Carolina, 'nd of these 15,617 were reported from
southern Georgia and Florida. During the 3-week period endin" Setor.mbc-r
s18, there were reported 3,175 cases from Florida; 125 from Georgia; 22
from Alabama; 49 from Louisiana; 2 from Mississiippi; and S froMn South
Carolina. All of those reports include infestations of blowfly ma7 ots
as well a s screwworm-s. During this period collections of larvoae were
obtained from wounds where possible, but only ones collected in the
stockyards at New Orleans, in southern Geor-'ia, and in Flirida were identi-
fied as C. americana. In the S-uthwestern States 93,952 cases of myiasis
were re orted from June 5 to Septerber 18 as follows: Arizona, 601;
California, 152; New .ic':ico, 15,137; Oklahomia, 666; and Texas (apro i-
mately 75 counties) 77,396. In these States control work is well
received by stockmen and the application of recommendations is reducing
cases by preventing infestations. From Septemb'r 1 to IS there were
16,445 cases as follows: "To -Mexico, 5,225; California, 88; Arizona,
317; Oklahoma, 266; and Tcxos,10,549. Of these cases, 2,l143 occurred
