INSECT PEST SURVEY BULLETIN


Vol. 17 September 1, 1937 No. 7



THE MORE IMPORTANT RECORDS FOR AUGUST

Grassho-opers continued to be the major entomological feature in the
Plains and Rocky Mountain States. Second-brood Melanoplus mexicanus Sauss.
are appearing generally in Missouri, N:ebraska, and the adjoining States.

Eg Great Basin.

The Gulf wireworm was found 112 miles north of the Gulf coast in Miss-
issippi during the month while the su.ar beet wireworm was more a-".,:ndant in
Ventura County, Calif., than ever before recorded.

A survey indicates that the white-fringed beetle is lightly infesting
about a thousand acres in Jones County, Miss. Th; -infested area in Walton
County, Fla., hos been found to be somewhat wider than heretofore known.

The vwriegnted cutworm did considerable da-mage to tomatoes, celery, -.nd
other truck crops in Indiana and Michigan.

An outbreak of the .garden webworm occurred e-rly in the month in eastern
Nebraska, principle damage being done to alfalfa. A very heavy fligit of the
moths was observed 1-lte in the 'month in Okl-ho',i.

The hessia n fly survey carried on in the West Central States indicates
that the fly is at the lowest population level ever recorded.

Heavy losses of late sweet corn anr.d tomatoes by the corn ear worm were
rep-oorted in the Middle Atlantic and E-st Central States.

The European corn borer was r- orted in destructive numbers in Connecticut,
Vermont, and New Jersey and on the East.,rn Shore of Virginia.

A very heavy population of thie potato leafhoy-ner ws reported from the
East Centr'l St-.tes, damaging )ifalfa and o-otatoes. Infcst.-.tion on potato
was so heavy in Wisconsin that practically all fields were brown before the
third week of the month.

Peak flihts of adult codling; moths vcre reported in the ur'n-or Hudson
River V-,lley on August 3; in DThla,.are on August 11; in Kko-( Cnunty, Ind., on


-335-

August 21; in Michigan on August 16; and in Wisconsin on August 15.

First-adult of the second brood of plum curculio appeared inMaine on
August 20. In Georgia 69 percent of the females started to deposit eggs by
August 20. ..

Herovy infestations of the -grape leafhopper were reported from northern
Ini-dirona .nid Ohio.

The walnut caterpillar ,was .very prevalent in southern hNew England, Middle
Atlantic, and-East Central State.s, and southwestward to Oklahoma.

False chinch bug is generally prevalent from Kansas to New Mexico and
Nevada.
Very heavy populations of squa-sh bugs were reported to be seriously
dnm.ging many cucurbltaceous plants in New York, Virginia, Iowa, Missouri,
Nebraska, and Utah. .

A rapid increase of boll weevil was reported in the South Atlantic States
and in southeastern Texas; however, the season is well advanced afd much cotton
already made.'

The. cotton leaf worm has been reported more abundant in Florida than at
any time since 1912. The insect was generally reported in small numbers over
the greater part of the Cotton Belt.

Cr'tton flea hopper injury was. in general, very low throughout the Cotton
Belt.

Heavy losses of cotton in the Imperial Valley, caused by the outbreak of
the cotton leaf perforator, occurred during the first 3 weeks in August. The
insect was also reported from Arizona.

Fall webworm outbreaks, in some cases of considerable intensity were re-
ported from the North Central, Middle Atlantic, South Atlantic, East Central
and Gulf States.

Elms in the New England States were seriously browned by the elm lacebug.
This insect was also reported as damaging elms in Florida.

Thousands of acres of forest in Maine have been defoliated by the European
spruce sawfly.

A detailed report on screwworm infestation will be fouhd in this number of
the Survey Bulletin.

An unusually severe infestation of stableflies is reported from the North
Central States.

Brain fever of horses, transmitted by mosquitoes, has become so serious in
the North Central States as to glut the market with dead animals at rendering
plants.

GENERAL FEEDERS

Grasshoppers (Acrididae)

Indiana. J. J. Davis (August 23): During the past month re-oorts of damage,
mostly to garden crops, were received from many different localities.
In many sections grasshoppers have been and continue to be very abun-
dant in grassy and weed.y areas with much less attack and injury to crops
than their numbers would lead one to anticipate.- Apparently this con-
dition is duo to the continued succulent vegetation in the breeding
places, preventing the need of migrating to cultivated crops. The
hoppers were most abundant in northwestern and northern Indiana; also
in the central-western region east to beyond Lafayette, and in Wells
County in northeastern Indiana where the hoppers were damaging young
grass as well as garden crops.

C. Benton and W. B. Noble (August 13-24): Adults abundant in
many localities of Benton, Tippecanoe, Clinton, and Tipton Counties,
Some damngL to corn leaves and ears in occasional fields in outside
portions next to fence rows, especially in Benton County.

Kentucky. M. L. Didlake (August 2)): Grasshopp-rs of several species,
among them lMelanoplus diffefrentialis Thos. and Dissostoira carolina L.,
attacked corn at Eddyville; tobacco, sweztpotatoes, peas, and beans at
Bowling Green; and Les)ed-za sericoa at Water Valley.

Minnesota. A. G. Ruggles (Aui-st): Grasshoppers are very abundant in the
southern third of the State.

Iowa. H. E. Jaques (August): Grasshoppers are from moderately to very
abunaCant throughout the State.

Missouri. L. Haseman (August 21): Hoppers continue to be abundant espe-
cially over most of the western and northern parts of the State. The
S two-lined oppcT'ers (,_. bVittatus Say) are practically gone. H. differ-
entiA:lsis m:,ting and femcles are c.-rrying mature eg. s. Th red-lgged
hopper (M. fe1sr-ru'Tur De.) in central. Missouri, is very scarce,
while M. mexicnus Sr.usP. is ap-oparently largely, if not entirely, in
the second brood and in places very abundant. Most of them are i. the
second to fourth insbtnr with a fc7 adults. Carolina locust (D. carolina)
was never so oundant as at the present time. The adults -rt prest-nt
in swarrms on all bare spots or cultivated pitches.

Nebraska. M. H, Swenk (August 20): Grass-hoppers continue to be the major
crop pest. Over 15,000 tons of bait m.rterials h,-ve b -r.n used. Whcre
the bait has been freely and properly aoplied the grasshoppers have
been brought under control and much of th. corn crone has been protected
from serious damai-c. Th- damage that has taken race is sTntted and
irregular in distribution, and mostly in areas where the pop'il-tion
was exceedingly heavy or control measure, s inadequate, or beth. In
the fall of 1935 there was a small and much localized hatching of









M. mexicanus in southeastern Nebraska; late in July 1936 there was a
much larger and more widely distributed hatch of this species; and be-
ginning the last week in July of this year, and continuing through
August to date, there has been'a large and important hatching of this
species involving the entire State, but much heavier in the eastern
part than in the west. This second hatching of this species is playing
a very important role in the late season control program., No ,second
hatching of M. bivittatus or M. differentialis has been observed. An
interesting phase of the situation, though not of great economic im-
portance, -is the unusual abundance of the lubber grasshopper (Brachy-
stola G ir.).

Kansasz H. R. Bryson (August 24): Grasshopoers arc not causing as much
injury as 'they were last year at this time. A trip from !Manhattan to
Jewell County through Riley, Clay, Cloud, Mitchell, Jewell, -and. Wash-
ington Counties revealed the fact t-hat the greater part of this year's
injury could not be attributed wholly to the large population of hoppers
but rather to the small amount 6-f green vegetation on whiqh to feed.
The greater part of the acreage in these counties had been prepared for
wheat, forcing the grasshoppers to seek food elsewhere. Pastures like-
wise offer very little vegetation for the hoppers. The greatest injury
.observed was in alfalfa fields. Injury to corn silks has been more
prevalent than ever reported before.

Okl2homa. F.'E. Thitehead (August' 20): Grasshoppers in the fields are def-
initely on the decline. Presurmably owing to extremely hot, dry weather,
the grasshoppers largely left the alfalfa and cotton fields and are
present in weeds, underbrish, along fence rows, and in dIraws. M. differ-
entialis remains the predominating species.

C. F. Stiles (August 24): Grasshoppers continue to do some damage
throughout the central and western part of the State. Prevailing species
are M. mexic-nus, MI. differentialis, anC. M. bivittatus.

Utah. C. J. Sorenson (August 22): M. bivittatus, M. packardii Scudd., M.
femur-rubrum-, and M. mexicanus are very abundant in southwest and north-
west Cache County.

G. F. Knowlton (August 24): Grassho-opers are damaging ripening
tomato fruits in many localities of Davis, Box Elder, and Weber Counties.
Large numbers are winged in all areas at this time.

Nevada. G. G. Schwcis (August 25): Grrasshoppers have moved in from waste
lands to cultivated crops in Douglas County, necessitating control. The
species involved are Camnulo. pellucida Scudd., M. meiicanus, and Oeda-
leonotus enigma Scudd.

010i.I01T CRICKET (Anabrus simplex Hald.)

Nebraska. M. H. Swenk (August 20): A specimen of Mormon cricket was sent
in from Grant County, in west-central Nebraska, on August 9, with the
statement that the insect is quite numerous in that locality.








Wyomir.n:. Salt Lake Tribune (August 22): There are billions of crickets in
those portions of the 'Yellronstone National Park w-.here tourists seldomn
visit.

-O,'Ga. G-. G. Schweis (AuLgust 25): The egg survey for Mrnorn crickets in
Elko, Humiboldt, Eureka, ahnd Lander Counties ha-s been completed for the
yeo'.r and the number of eggs indic-.tes that there will be a hewv-y in-
festation over a wide arca next year.

IPrE7OP2,1S (Elatoridae)

Mississippi. K. L. Cockerhanrz (August 9): One adult, He'tertdcres laurentii
Guer. ; was found. August 9 by J. P. Kislanko at Laurel, Jones County.
This is a new locality r-cord. and cztends the spread '112 niles north
from the Gulf coast.

California. R. E. Campbell (July 23):' Quoting U. D. Miller, assistant
agricultural agent, Ventura Cou.nty: "Wireworm moe in Ventura County
has been nmore wvid.espra. and saewre than any of the oldest inhabitants
can recollect. Farms which have never been previously infested show
a surprisingly heavy d.an:age this yea.r."

A WMITE GRUB (Phylloohaga ephilida Say)

Maryland. E. N. Cory (August 6): May beetles are severely injurious in
Queen Annes, Talbot, and Saint Marys Counties.

GREEII JUNE BEETLE (Cotinis nitida L.)

Georgia. 0. I. Snapn (Augist 1): The green June beetle is unusually abun-
dant at Fort Valley, central Georgia, fe-ding on ripe peaches. ,Many
fruits were ruined..

T. L. Bissell (Auuist 9): Green June beetles h.ve been swarming
in abundance for the last 2 days at Griffin. They evidently emerged
after showers on Auust 7, which h ad followed a .dr period. Beetles
fly over grass and up into trees as long, as the sun shines. I have
never before seen such a flight of this species. Individual beetles
have been oit some wee.ks.

Kentucky. M. L. Didlake (Aujist 24): Green June beetles destructive to
peaches in Lexington.

JAPATESE BEETLE (Poillia japonica in. )

New England and New York. E. P. Felt (August l4): The Japanese beetle has
increased greatly in southwestern I'-w E, land and southeastern New York
and has been found in some numbers in several Icc'-lities in tne southern
Berkshires of Massachusetts.

Connecticut. W. E. Britton (Au: st 21): The Jaoanese beetle is racdually
becoming- more prevalent. It is present in all the cities a.n larger





-34o-


villages of the State, but is not yet found throughout the open country
districts. Heavy infestations occur in Branford, Bridgeport, Darien,
Greenr.7ich, Hartford, Now Canaazn, New Haven, New London, Putnam, Ridge-
field, and Stamford.

New York. N. Y. State Coll. A:?r. News Letter (August 16): Japanes'e beetle
has been troublesome in sections of Westchester County where it has
never bcoUn before.

Delaware. L. A. Stearns (Aulgust 24): Infestation for the present yearx about
ended; but few beetles now in evidence except on especially susceptible
hosts.

ASIATIC GARDEN BEETLE (Autoserica castane.. Arrow)

Connecticut. 7T. E, Britton (August 21): This beetle is rapidly becoming
more prevalent in Connecticut. Di4ring the past month adults have been
received from Darien, Greenwich, Hraiden, and Norton, ,and three lots from
New Haven.

WHITE-FRINGED 7WESVIL (Naupactus leucoloma Boh.)

Florida. J. R. Watson (August 23): Extensive scoutin-'-in Walton County has
resulted in somewhat widening the known infested area.

I1ississippi. C. Lyle (August 24): The first s-ocimens of the white-fringed
beetle in Mississip-piA were sent to this office from Laurel on Aui-st 6.
Inspectors have found that -about 1,000 cres inr; Jones County are lightly
infested. The infestation is largely confined to the city limits of
Laurel, an. 'so far it has not been fou(id in the farming district.

CUT7OR.IS (Noctuidae .

In&di.ana. J. J. Davis (August 23):. During the month considerable damage in
central Indiana was observed by the yellow-striped ar myworn (Prodenia
ornithogalli Guen.) and the variegated cutwIorm (Lycophotia margaritosa
saucia Hbn.) eating into the green fruits of tomato. In all cases coming
under our observation the infestations occurred along borders of fields
or in fields which were grassy and weedy.. TWhat was apparently the varie-
gated cutworm wias reported eating into the heads of cabbage August 10 at
Borne. .

Michigan. R. Hutson (AuTist 17): The varicated cutworm attacked celery in
the vicinity of Inlay City dcurinf the first weck of. August, The infesta-
tion embraced practically the entire celery-growing district in that
vicinity, but the cutwvorm did not occur, in. other celery-growing districts.

Nebraska,. N.' H. Swenk (Aug-ast 20):. A Gage County, correspondent reported the
yellow-striped armywormr to be present on, his flowers on July 26.

Arizona. C. D. Lobert (August 13): During the. last of J.ly, and the first of
August in the East Verde area, northeast of P.ayson, there was a rather




-341-


heavy infestation of the arinywor.m (Cirphis unipuncte Haw.) nid the
variegated cutworm. They were working together on alfalfa,, .-'aden
crops, and young fruit trees. Rath,-r severe d.a-na;e was observed.

California. A. E. Michelbach-r (Au4ust 13): In certain scatt(.red locoali-
ti.s through central California the yellow-striped armyworm (ProdJ1ni0
praefica Grote) hs caused somc d inaje to the developing fruit.

FALL ARI"YWORM (Laphyrna frugiperda S. & A.)

Goorgia. T. L. Bissoll (August 17): 7orns ncre found shredding the leaves of
young corn at Griffin, central Georgi. This is the first injury noticed
this year.

VELVETDEAl CATERPILLAR (Anticarsia genmamtilis Hbn.)

Florida. J. R. 7atzon (August 23): Pe-anuts in Alachua County have in many
cnc s bcen severely attacked by the Vwvttbean caterpillar.

Louisi-an-,. B. A. Ostcrberger (A.u'-st 25): We have records of activity
from :-poleonviLlo to Fr -.nklin, Crovley, Baton Rouge, and Hanmond. The
present generation is developing rapidly and moths for the next genera-
tion' arc beginning to emerge and lay e-s.

GARDEI 7EBWORM (Loxostege similalis Guen.)

Nebrask?.. :. H. Swenk (Aupust 20): The largc flights of moths occurring
at Lincoln in mid-July resulted i- an outbreak of wcbv,'orms during ; the
week of July 28 to August 3. 'This outbreak was most severe in Richard-
son County, where damage was done in the alfalfa fields and arni s of
the webworms crawled into occupied houses. Daage was rep rted north
as far as Butler, .Madison, and Antelope Counties, chiefly i:n the alfalfa
fields, but also in cornfields and pa-stures.

Oklahoma. C. F. Stiles (August 24): Su;:-.,y night I sa,,w one of the heviest
flights of the r.moths that I h:vc ever seen. Thousands werc flying;
P.round the lights.

MHITB-LI!ED SPiI:X (Sphinx linoata .)

XR-YiWORM (Cirphis unipuncta- Haw.)

Maine. J. H, Ha.wkins (Au.'n.st 7): Fields orf oats and .r:.ss were seriously
injured in central and ncrth-central Maine. Oats were cs-)ecial1y
dca71r '-d, in some cases holec fields being destrnoycd or injured t, such







an- extent tihjt they were not harvested..

MiDnne sota. K. A. Kircptrick (Auru't 24):.' Armyworms have been quite abun-
d:,nt in several places iI Hennopin Co.nty', one 'farmx'r reporting 30 per-
ce-nt' loss on his' grain. .. ...... ..

rather heavy infestation ..... ..

California. A. H. Clark (July): Specimens were sent from Los Angeles with
the statement that moths occurred in..thousands in a.:-small home- garden.
(Dot. by C. Heinr.ich.. ) :

*HESSIAN LY (?hytoph'a'a destqru.ctor' 'Say)

General. J. R. Horton (June): A hessian fly survey conducted shortly before
harvest last JuI.e indicates that the6flypopultion has no%: reached its
lowest oeneral level' in all 'the yearr of systematic record for the region
comprising the States of Kansas, Missouri, Nebra..k?, and Oklahoma. At
the present time infestation is, 6n the average, below the 10 percent
level in all portions of these States.- :;-. samples r-.njed from 40 p'rccnt -dow7ard to 24 percent and occurred in
the southern and east-central portions,,of Missouri, particularly in
Greene, Dallas, Scott, and. Perry Count'ies'. and, il esscr decree, in
Craford.., Osoa maxima ,'-orthy of ,special mention occurred the hi;hest.individOul-sample
infestations beii;n,, 1g 1 ac 22 percent, in northeastern -Kansas and south-
eastern Nebraska, respectively. ..

UTROPEAi =HEAT STEIMI SATItY (Cephus ,py; rcus L.)

Ohio. E. J. Udine (July): Heavy infestations, of the, wheat sawfly in eastern
Ohio. Actual d-;nrLg by it was less than usual owin,to a delayed develop-
mernt of the larvae which enabled harvesting to occur before the culms
were severed. .

CORN. .

CHINCH BUJG (Blissus leucopterus Say) .

India _a. C. Benton and W. B. Noble (August 13-24): A. survey in west-central
Indiana covering 20 cornfields per county and 24 stalks per field showed
the following average infestations of combined ad ,ults and nymphs:

The proportion of ny.r..ph. to -adults increased from ,bout 4 to 7 at the
beginning of the survey to about 5 to 3 at th end. The- majority ,of
the -n- hs belonged to the first three instars. Foxt-til ;rass is .bun-
dant in some fields and moderately infested with nymphs.

Kansas. H. R. Bryson (August 24): Chinch bugs arc scarce in Kansas.

Oklahoma. C. F. Stiles(Augist 24): Chinch bugs have also been reported in
dama':ing numbers throughout the central part of the State. The infesta-
tion is very light on the western side of the State.

CORN EAR 7ORM (Heliothis obsoleta F.)

New York. N. Y. State Coll. Agr. News Letter (August 16): Many sweet corn
growers are experiencing heavy losses in Westchester County.

New Jersey. E. Kostal (Au.ust 25): This species is very seriously damaging
late sweet corn in Morganville, 1,onimouth C-unty.

Maryland. L. P. Ditman (August 23): Corn car worm developed earlier this
year than usual. Injury .was especially heavy on tomatoes. Infestation
fell off during the latter part of July and first of .August, but it be-
com:. severe during the past 10 da-ys.

Ohio. T. H. Parks (August 26): 7hile injury was very severe to early rmaturing
sw.ieet corn and to early tomatoes, its presence in mid-season corn is not
much above average. We look for a heavy infestation in late sweet corn.

Indiana. J. J. Davis (Aug-ast 23): The second br;od has been very abundantt,
attacking corn, but the infestation in tomatoes by this brood has beer
negligible except where they adjoin cornfields. The third brood.is just
appearing- and is showing up slightly nore on tomatoes than the second
brood.

E. V. Walter and C. Benton (August 13-2)4): Infestations in sweet
corn at Lafayette have been from 20 to 50 percent, with the r.airity of
worms nearly full gro-wn. Infestations in field corn averaged 10 to 20
percent.

Illinois. W17. P. Flint (August 23): To date the corn ear- worm has been only
moderately abundant, though a heavy late brood is developing.

Missouri. L. Haseman (August 21): Thile most fields of corn show heavy in-
festation, sweet corn at Columbia is imch less severely infested than
one might have expected from the severe infestation in the tassels of
corn earlier anl in early tomatoes. At present very few worms are show-
ing up in tomatoes in central Missouri.

Utah. G. F. Knowlton (August 24): Moths are found in s-.-ill numbers at trap
lights in northern Utah. Damage to sweet corn is rather heavy in northern
Utah.

Nevada. G. G. Schweis (August 25): Damage to sweet corn sees to be decidedly
less than a year ago.










EUROPEAN CORN BORER (Pyrausta nubilalis Hbn.)

Vermont. H. L. Bailey (August 20): For the first tiime in Vermont borers
have been found in considerable numbers in potato stalks in Rutland.
and Chittenden Counties. Many larvae apparently full grown. at Ira,
Rutland County, southwestern Vermont.

Connecticut. WT7. E.Britton (August- 23): Larvae of the second generation
are nowv very prevalent iz the New4 Haven region and' cause much damage
to the cars of sweet corn and the shoots and buds of dahli:.

Now Jersey. R. Kostal (August 25): This species is very seriously dnamging
late sweet corn at Mor'ganville, Monmouth Cou'nty. n" .

Virginia,. H. G. Talker and L. D. Anderson (August 29): This has been a very
favor-.blo yerr for the development 'bf the Europon' corn borer on the
Eastern Shore of 'Virginia. The second, generation of borers has done
considerable damage in some fields of early corn. One stalk was dis-
sected which contained 30 full-grown larvae 'or pupae. Moths -of the
third generation are now in flight and over 350 eggs havebeen counted
on some plants. A great many plants ini a field of corn near Onloy
have over 100 oggs now and eggs are still being deposited.

Italy. H. D. Smith (July 30): Our Itali.n field assistant reports vory
hervy infestation of corn borer in the Province of Mantova, heaviest
in years. About every plant infested. Corn exceptionally early this year.

SOUTHZRN CORN ROOTWORM (Diabrotica duodecimpunctata .F.)

Indiana. J. J. Davis (August 23): Since our report a, month ago, accordss of
injury to corn reported from the' .nrthwestern quarter of the State. No
reports received since Augu.st 1. "

C. Benton and 7. B. Noble (August 13-24): Adults of.D. duodecim-
punctata are unusually abundant eveoryh-,re on corn in Benton, Tippe-
canoe, Clinton, and Tipton Counties, mostly behind the leaf sheaths
and in. the silk. In Benton County D. longicornis Say was abundant and
largely replaceC. D. .2-punctat ...

Kentucky; M. L. Didl` in control Kentucky.

Missouri. L. Hascman (August 21): During August they have been very abundant
in central Missouri. These are the adults from the rootworms which were
so destructive during July, especially in the central part of-the State.

CORN LANTERN FLY (Percgrinus maidis Ashm,)

Florida. J. R. Wa.tson (August 23): The corn lantern fly about ruined late-
-olanted corn in Alachu. and other counties.

Inciana. J. J. Davis (Auust 23): The past 2 months have witnessed: one of
the most destrnictive attacks on alfalfa that v:e have observed since our
earliest records (over 20 years i ... Th, i:festation was ,en.ral through-
out the State. The obscrvrtions reported la.t mcnth indicated much
greater injury, in the southern half of the State.

Kentuclky. M. L. Dirlakce (Aur-ust 214):- Destructive to olfalfa in central and
western Kentucky.

ALFALFA CATE-_PILLAR (Eurymus .ur.'theme 3dv.)

Arizona. C. D. Lebert (Au;ust 13): In thie Salt River Valley near Phoenix,
Mesa, ni-. Gilb-rtthere has bern severe injury to alfalfa by the alfalfa
caterpillar. Some fields in the M1esa-Gilbertarea are almost compl-tely
cffo i-:tcd. Thousands of th9 butterflies have been seen in the valley.
Every tourist coming through the valley is carrying a display on the

After water hae' been drained .from fields the: beetles gn in and gnaw
the stalks at or just b,-neath the surface of -the !soil. Farmers have
been forced to cut rice before it was mature. In some fields 22 per-
cent of the st..alks are being gnawved..: This hs not only reduced the
yields but has prevented maturity of some of the rice that will be
threshed. and lowered the F;rade on account of chalkiness.

second-brood entrances are beginning to show up but are, still hard to
find. An occasional late sting is showing up in some orchards in Orange
County, but the injury is not -great e-nough to necessitate special aopli-
cations by growers.

D. -. Hamilton (AuGust 2,4): At Poughkeepsie peak. activity of first-
brood moths, as indicated by bait traps, occurred on the night of AuOgust
3. Moths continued to appear in bait traps until August 21. Since then
the tamperaturelhas been too low for moth activity. Bands examined on

Indiana. L. F. Steiner (August 25): As indicated by bait-trap caotures,
second-brood. adult activity reached its peak in three orchards in Knox
County (southwestern Indianar) on Aug-ust 21, 2 days later than in 1936.

in July, this ye-ar they continued to emerge until-,about the middle of
Au,-;ust, thus overlapping with early 'third-bro6d moths. Second-brood
larvae have been especially noticeable in central Missouri 'since about

H C,: SES

S*STABLEFLY (Stomoxys calcitrans L.)

General. F. C. Bishop (September- 2): A rather severe outbreJak of stableflies
beginning -bout the middle of July has continued to cause considerable
losses to farmers and stockrais, rs in the North Central. St-.tes. In the
grazing area of southern Kansas cattle were reported to have suffered an
avoraL:e loss in weight of 50 pound peor head on. account of the pest. Recent
reports from Iowa indicate that the outbra-k is beginning tc subside in
that State.

Iowa. S. 7. Simmons (June 23 to July 13): In a survey of 37 farms in the
vicinity of Ames the stablefly was the w.orst of all insect pests of horses.
Of the 101 animals examined 19 woere mules. It was the opinion of their
ovmers, in all instances except one, that stableflies wVere worse on mules
than on horses. One farmer owning both. miles and horses, said that he had
not been able tr, use his mules on several. occa.sions due to the abundance
of stableflies. Examinotion revealed the preference of stableflies for
mules. It is estimated th.-.t -.bout 80 percent 7,f the farmers regularly
use nets on their ,-ork animals as protection a m.inst the stablefly. In
quite a few instances farmers sira,-ed their animals throe or four tines
daily. Some farmers carried sprays with then.

Missouri. L. Haseman (Au.-st 21): Stableflies have been less abun' rt and
vicious than during; July.

United States. F. C. Bishop (Augutst): Brain fever, or encephal.oivelitis, of
horses has appeared in serious epizootic proportions in the North Central
States, especially in Minnesota, South Dakota, Nebraska, and Icwa. Heavy
death losses are reported. RenderinC plants are unable to handle the
dead animals and the' farmers are seriously handicapped. The disease is
also present in Colorado, Wyoming, Utah, Texas, Virginia, and Maryland,
and probablyother States are involved. It is important that all informa-
tion possible 6n the relative abundance :and distribution of various mos-
quitoe and.'biting'flies be g.,thcred throughout the affected areas.
Georgia., J. B. Hull(Juiy):- Increased rainfall during July has apparently in-
creased the abundance and annoyance of the salt marsh mosquitoes Aedea
sollicitans Walk. and A. 'taeniorhynchus Wied. with the former the most

area, in which an outbreak of equine encephalor:.yelitis is now occurring.

Oregon. H. H. Stag.,e (July 16): A severe epidemic of the mosquito Culex
tarsalis Coq. whs -roported from Lebanon. This species is seldom numerous
enough to constitute a pest. A. vexans Meig. and A. aldrichi Dyar and Knab
are not abundant in the Portland area. In fact, samples t.aken- at various
points in .hMltnomah County give but 10 to 30 percent of the numbers taken
ini 1936. A. vexans, which has been severe heretofore in and 'about Hood
River, has booeen of no consequence this season. The so-calleId snow or
Mountain species, A. comnunis 'Peg., A. hexodontus Dyar, and A. aboriginis
Dyar, have been reported as extremely annoying in several. isolated dis-
tricts throughout the Cascade Mountains.
