at this point 26.5 per cent of the crop ;was infested. Under date of June 15 Mr. W. H. Larrimer reports from Salem that 3 per cent of the
crop is infested this year as compared vith 23 per cent infestation last year, and under date of June 25 he reports from Logansport that 14 per cent of the crop is infested as compared with 53 per cent last
Illinois W. P. Cartwright (June 13, Grand Chain). "Fifty-five per cent of culms
infested as compared with 53.5 per cent infested last year. At Sparta
23 per cent of the culms were infested as compared with 24 per cent
infestation last year. (June 17); at Centralia, 0.3 per cent infestation as compared with no infestation last year."
7. P. Flint (August 18). "Several local areas of heavy infestation in
the south and south-central parts of the State. The insect seems to
be about 50 per cent parasitized."
New York C. It Crosby (survey f cr 1921). "Joint7crm survey was carried on in
15 counties in New York State. 13 in the western part of the State, and 2 in the southeastern part of the State. The average infestation for the 15 counties was 2.89 per cent. The percentage infestation in the
several counties was as follows:

New York C. R. Crosby (survey for 1921). "In connection with the Hessian fly
and jointworm survey this insect vwas found in 5 counties. The
average infestation of these counties was 0.79 per cent. The percentage infestation in the several counties was as follows:

EUR0I7IN C(RN B(RER (Pvrausta nubile lis Hbn.)
New York L. 0. Gratz (July 30). 'Tasily found in any field at Eden in Erie
County. Many ears have been discarded from the marketable lot. Last
year a few larvae were reported, but this year apparently marks the
beginning of a serious infestation."
P. Z. Hartzell (Augist 13, Chautauqua County). "Present in the
northern part which is under quarantine; numbers not great, however."
--190Pennsylvania W. R. Walton (..ugust 26). "During August the following tow;ins in the
extreme northwestern part of Pennsylvania bordering Lake Erie froM the New York State line to the Ohio State line have been found infested: Harbor Creek, Greene, Mill Creek, Summit, McKean, Fairview,
and Springfield. The township of Girard had been found infested
two years ago and is still included in the infested area*"
Ohio W. R. Walton (August 30). "Infestations of the corn borer were
discovered during the month of August in the following localities
in Ohio: North Bass Island, Middle Bass Island, South Bass Island,
Kellys Island, Catawba Islands and the toms of Danbury, Portage,
Huron and Avon Lake. These islands extend at least half way
across the lake toward the internal tional border at the viestern
end of Lake Erie just north of Sandusky, Infestations have also
been discovered in the northeastern corner of Ohio, bordering
Lake Erie in the townships of Ashtabula and Saybrook and continuously along the lake as far west as Willoughby."
CCEN EARVK (Chloridea obsoleta Fab.)
New York F. Z. Hartzell (August 13). "Some injury at present in Chautauqua
C. R. Crosby and assistants report finding this insect in sane f
fields in Erie County on July 22, a second infestation being
noted in the same county on August 20 in late sweet corn. In
the middle of July it was doing considerable damage to early sweet
corn in Nassau County, being only occasionally found on the
later corn in the middle of August. Early in July it also did a
slight amount of damage in Columbia County."
Illinois W. P. Flint (August 18). "M1uch more abundant in both field and
sweet corn than during an arerge yw;.r. Seventy-five per cent
of the sweet corn ears being infested. Moths of the third
brood are just starting to amear."
Missouri L. Haseman (August 29). "The corn earworm is increasing in numbers
and has been reported from various sections of the State."

Illinois 7. P. Flint (r!-ugust 18). "Moths h.ve been taken comonly in bait
traps for the past three weeks in Central Illinois."
Florida J. R. Watson (August 16). "Quite numerous throughout the State but
confining their '-crk mostly to the grass crops.,
XIissouxi L. Haseman (August 29). "Just recently the fall army worm has begun to attract attention, and in central Missouri the larvae of the present brood are now half grovm. They are damaging sweet corn and other garden crops, but as yet have not been reported
on alfalfa or other legumes."
Louisiana T. H. Jones (August 9). "An outbreak noted on the grounds of
the Experiment Station attacking grass and lov .groujing crops in
grassy fields at Baton Rouge."
SUGa-ChNE BORER (biatraea sccharalis Fab.)
Louisiana T. H. Jones (August 16). ",Ir. W. R. Dodson estimates that in
about 200 acres of late corn planted during the last week in April and thD first week in 'Iay the loss will be about 5,000
bushels of corn because of the severe infestation of this
insect. The stalks and ears are very badly attacked and in
the case of the ears secondary causes, such as other insects, fungi, and bacteria, will make them Largely unfit for feeding
CHINCh BUG (Blissus leucopterus Say)
Indiana J. J. Davis (August 16). "Immature chinch bugs have been present
in abundance in corn, although heavy r%ins for the past vwoeek mtay
have reduced their numbers somewhat."
Illinois W. P. Flint (August 18). "Heavy general rains have greatly reduced the number of bugs in most of the counties infested early
in the year. In only a few counties %ill corn be seriously daeagedo
The ] parasite Eumicrosoma benificia has destroyed from 30 to 40
per cent of these insects."
Miichigan R. G. Carr (august 10) "a slightly larger infestation than usual
occurred this year at adrian, whore about 10 per cent of the crop
was damaged. The use of furrows and barriers was quite successful, many bushels of the insects being thus killed."
Nebraska Id. H. Swenk (August 15). "Shortly after the middle of July an
outbreak of the chinch bug developed in Xnox County in northeastern Nebraska, after injury in the infested area alcng tha southern border of the State ihad ceased. The bugs were first noted
in the barley fields and when these .Fere harvested they migrated
to the corn and did a considerable mount of damage in scme fields."
Florida Jeff Chaffin (August 21). "eports from all over the State indicate
that this insect is doing considerable damage to lawns, especially
St. Augustine grass, which they seem to prefer."
Missouri L. Haueman (August 29). "Some corpliints continue to come in
regarding the damage from summer broods of chinch bugs, but the
abundant rainfall of the past few weeks seems to help materially."
WHITE GRUBS (Phylluphpa spp.)
Illinois W. P. Flint (August 16). "Severe damage to corn rep rted frozi
10 r 15 counties in the northern half of the State, mainly corn on sod or small grain stubble. Blue grass pastures also severely
Wisconsin S. B. Fracker (August 25). "Damage is not as severe as in other
white grub years. Crows are reported as attacking the grubs
in large numbers at Platteville."
AiFAIFA AND CLOVER
BLISTIZR 3LLE (Epicouta lamniscate Feb.)
Nebraska Ayron H. Swenk (August 15). "The striped blister beetle continued
injury during latter July on alfalfa nd potatoes, especially in
Thayer and Adams Counties."
CLOVER -APHIS (Anuraphis bakeri Gowen)
Idaho R. H. Smith (Aiugust 15). "This insect is less abundant than usual
this year. Unusual reinf.ll during ilay and June probably prevented
this post from becoming seriously destructive."
CLOVER ROOT-BORER (Hylastinus obscurus !Jarsh.)
Oregon 7. P. Rockwood (August 13). "Damage by this pest is more severe
than for the post two years in many first-crop clover fields. Dry
weather has retarded gro-th of clover roots and high temperatures haee accelerated thu development of root borers. Fields on pooror soils most seriously damaged."
CLOVER SEED CHALCIS (Bruchr_.ba us funebris How.)
New York L. P. Wehrle (Aiugust 16). "Adults now present and fairly common
iLFLFA CAT=EPPI JR (Eurymus eurytheme Bdv.)
California H. G. Smith (August 20). "r. Fred C. Blossius reports having
the worst infestation of this post that they have had in the prst five years, the insects destroying about 25 per cent of
the third and fourth cuttings,"
CLOVER SEED CATERPILLAR (Enarmonia interstinctana Clem.)
New York L. P. Wehrle (August 16). "Second-brood moths have been on the
wing for about 2 weeks and eggs are now being deposited. The
insect is fairly abundant about ithaca."
COVICI-SEED AIDGE (Dasyneura legumnicola Lint.)
New York L. P. Wehrle (iAucust 16). "Second-brood larvae are now beginning
to appear. Adults in flight and ovipositing. Judging from the abundance this season this insect will probably do considerable
damage. It is the most important clover seed pest in the vicinity of Ithaca."
LESSER CIOVER-L~A EEVLL (Phlytonomus nigrirostris Fab.)
New York J. D. Detwiler (July 25). "This insect is very scarce about
Ithaca this year, due probably to heavy parasitism early in the
C 0IPFA S
C 7PEA CUROULIO (Cha lcodermus aeneus Boh.)
Mississippi R. W. Harned (August 29). "Coupen-pod weevil seems to be more
abundant than usual, Reports of serious damage to cowpeas have
beeii received from Adams, Itawamba, Lafayette, lauderdale,
Pontotoc. and Vayne Counties."
Louisiana T. L Jones (July 11). "Mr. T. H. Casonova, county agent of
Vermillion Parish, reports thIt this insect is doing some
daPage in his parish."
BEAN LEAP-BEETIE (Cerotcmna trifircnata Foerst.)
Louisiana T. LH. Jones (July 12). "Serious damage to the foliage of cowpeas growing in corn fields noted in Lofourche Parish."
T. H. Jones. "M1r. C. B. Gouaux, engaged in extension work in agriculture for Louisiana State University, reports that while on a recent trip he found this insect causing severe damage to
cowpeas in cornfields in the Paincourtville, Napoleonville,
and Franklin sections."
SOUTHERN GEEN PLANT-BUG (Nezare viridula L.)
Louisiana T. H. Jones. 1r. C. B. Gouaux reports that he found all stages
of this insect very numerous on ca peas in the cornfields in the
Paincourtville, Napoleonville, and Franklin districts."
VELVET BEAN CfTRPILI.R (Anticarsia gemmatilis IHabn.)
Florida (Special Report No. 16). "Reports have just been received from
Mr. J. R. 'atson and Mr. Jeff Chaffin that the velvet bean caterpillar has just appeared in central and northern Florida. Adults were first observed at Cocoa in Brevard County on August 15 and at
Gainesville in Alachua County on August 16. From previous observations this insect should be expected to reach southern
Georgia by Septenber 1 and southern South Carolina by September 10.
This insect is a serious pest to the velvet bean throughout
Florida and southern Georgia and, though the moths in their annual flight have been recorded as extending as far north as southern New York, it is not recorded as a serious pest of any other
MISCELLANEOUS CEREAL AND P FORAGE INSECTS
GRASSHOPPETS (Acrid i idae)
New York G. E. Smith (July 23). "As early as July 16, grasshoppers .ere becoming very abundant in most sections of Orleans CotUnty and doing

CODLING ILT: (Carpoca psa pomonella L.)
ew York G. R. Crosby and assistants report about 5 per cent of side worm injury
observed in Eay-ac Icrunty on July 15. On same date a larva was observed
which was apparently ready to pu ~ae; the majority of the larvae, however, were not more than about two-thirds grown. In Orleans County
side worms were rather abundant in most orchards by July 23, especially
those which received no June spray; five orchards inspected during the
third week in July which received a thorough spray between June 15 and
25 showed but very small percentage of damage; larvae in most cases were then about half gronm; by July 30 most of the larvae were full
gram in this county and many had begun to pupate, and by August 6 a majority of the larvae had pupated. On August 8 moths of the second

Alabama E. Hinds (August 26). "Boll weevil dAmage in the central and
southern part of the State is less than had been anticipated at the
beginning of the seasqn, because of the control of the first generation of weevils by the hot, dry weather occurring during the month of June and most of July in most of that region. Fields,
however, that received more rainfall are suffering heavier damages.
In northern Alabama the injury from the weevil is heavier than it
has been in any previous year. As a general rule comparatively little dusting control has been practiced this season,"
Mississippi R. W. Earned (August 29). "The boll weevil is very abundant in all
parts of the State, The entire State is now probably more seriously infested than ever before at this season of the year,"
Texas M. C. Tanquary (August 22). "Infestation continues to increase in
the vicinity of College Station in spite of the dry, hot weather.*
COTTON APHIS (Aphis gossypii Glov.)
Texas M. C. Tanquary (August 22). "During the latter part of July and
the first week in August there was a heavy infestation in some cotton fields at College Station. The infestations have been
greatly reduced by parasites and climatic conditions."
BOLLWORM (Chloridea obsoleta Fab.)
Texas M. C. Tanquary (August 22). "Since July 22 many complaints have
been received concerning damage to cotton by bhe bollworm. The
infestation seems to be quite general,"
COTTON WORM (Alabama argillacea Hubn.)
Alabama W.E.Hinds (August 26) "The cotton leafworm has just been reported
from Benton, Lowndes County, occurring upon some very late planted thrifty young cotton in which boll weevil damage is also very heaV$
The initial occurrence of this species is so late that heavy ddfoliation is not anticipated for this season-"
Mississippi R. W. Earned (August 29). "Reports of the appearance of the cotton
worm have been received from various parts of the State,"
GRAY HAIR STREAK (Urenotes melinus Hubn.)
Louisiana T. H. Jones (August l)."County Agent W. H. Humble sent in infested
squares and larvae collected at Alexandria."
SUGAR-CANE MEALYBUG (Pseudococcus calceolariae Mask.)
Louisiana T.H.Jones. '"Mr. Gouaux reports on returning from a field trip
that the mealybug is common on sugar cane in fields about the mills and refineries in the Franklinj Gramercy, Reserve, and
Paincourtville sections. Their abundance in such fields as compared with other fields of the plantations is apparently
due to the fact that the Argentine ant which attends the
mealybug is more numerous in the fields about the mills and
FALL ARMY WORM (Laphlyma frugiperda S.& A.) Louisiana T. H. Jones. "Mr. W. A. O'Neill reported an outbreak of these
insects on his plantation at Baldwin early in July."
NORTHERN TOBACCO HORNWORM (Phlegethontius quinquemaculata Haw.) New York C. R. Crosby (July 20). "Doing considerable damage about Cato."

COLUMBINE BORER (Papaipema purpurifascia G.& R.)
New York M. D. Leonard (July 30). "Plants in the College gardens at
Ithaca badly affected. Larvae about full grown on July 18."
SUGAR-BEET THRIPS (Heliothrips femoralis Heeger)
Indiana H. F. Dietz. "Was observed to be injuring cyclamen and chrysanthemumn in an Indianapolis greenhouse July 15. On cyclamen many of the laaves were badly curled and crippled due to the attacks
of these insects. The injury closely resembles that caused
by the cyclamen mite."
GOLDEN GLOW APHIS (Macrosiphum rudbeckiae Fitch)
New York E. P. Felt (August 1st). "OccasioneA considerable damage to
golden glow at Big Moose."
FLOWER THRIPS (Euthrips tritici Fitch) Indiana H. F. Dietz. "Gladioli growers, especially those who have no system for irrigating or artificial watering, have experienced
trouble with the wheat thrips."

INSECTS ATTACKING MAN AND DOMESTIC ANIMALS
COMMON CAT AND DOG FLEA (Ctenocer halus canis Curtis)
Massachusetts H. T. Fernald (August 20). "Recently fleas have been very abundant in many parts of the State following the warm and
rather damp weather of late July and have been so troublesome
as to attract considerable attention in many places."
Indiana H. F. Dietz (August 16). "Fleas in houses have been frequently
reported to date. Every report has been checked back to the
presence of either dogs or cats in the places."
Central States F. C. Bishopp (August 22). "There seems to have been a marked
diminution in the outbreak of fleas which occurred during
spring and early tttier in the central States. All the specimens
examined were Pulex irritans, but the trouble has extended
eastward into the north Atlantic and New England States.
During August house infestations were reported in a number of
localities in that section. In the lots received Pulex.irritans
Ctenocephalus canis and C. felis were found to have occurred, $sually the cat and dog fleas occurring together and the human
fleas alone. It appears however that cat and dog flea predominates
in these districts."
DEER FLIES *E g E.
New York R. C. Shannon (August 7). "1Chrysops vittatus was present and
causing some annoyance at Conquest. Collected Chrysops obsoletus
Texas 0. G. Babcock (July 29). "Considerable increase over last year.
Sticks, horse d-ung, etc. are well cceredi wh the cemented
dirt covering by these ants in the pastures."
New York R. C. Shannon (August 7). *Collected a specimen of PsoroPhorr
ciliata in the act of biting near Conquests Anophels w": rii
was abundant and very annoying during the whole nipht at
Conquest and was also collected at Fairhaven,"
Indiana J. J. Davis (August). "We have had numerous inquiries relative to
ridding houses of ants. Where specimens have been submitted we have found the most serious offender to be the cornfield ant."
Alabama W. E. Hinds (August 26). "The Argentine ant is causing serious
complaint and is found scattered through the principal towns and
cities throughout the State. Campaigrns for ant control have been
started in 10 commnities including the City of Mobile ard Selma
which are the largest infested areas known at this time."
Mississippi R. W. Harned (August 29). "TM Argentine ant, Iridomyvrexy humilis
has caused more complaint this s=mer than ever before. The Plant Board is planning to put on control campaigns in several towns in
cooperation with the local authorities."
HORN FLY (Lvoerosia irritans L.)
Texas 0. G. Babcock (July 29). "Horn fly has been at its height the
latter part of June at Sonora when they were numerous co gh to
gather about the base of the horns at times. Now al~eost gone,
average not over 25 per animal."
F. C. Bishopp. "The horn fly became abundant in Dallas and adjacent counties in May, but decreased rapidly durin- June and
is not causing serious annoyance to live stock in J:2y. In
south Texas the abundance was rather above normal d' injg June."
HORSE-FLY (Tabanus rubescens Bellardi)
Texas F. C. Bishopp augustt 20). "In southwestern Texas where this
species occurred in injurious numbers earlier in the year it has
decreased very markedly and is now causing no annoyance to live
stock. Reports have been received, however, from the vicinity of
Jacksboro of the unusual abundance of this species daring July,
but there also the number is rapidly decreasing."
STABLE FLY (Stomoxys calcitrans L.)
0xas O. G. Babcock (July 29). "The stable fly was practically -nknown
until the last two weeks w en they have increased just enough
to be noticed and to bother the legs of milk cows."
F. C. Bishopp "Throughout the spring this insect was present in more than usual naurs in ,o: ch centr: -. Texas. It has subsided
remarkably during June in the ratnrilo hot, dry weather,"
SCREW-WORM FLY (Chs ay macellaria Fab.)
Texas D. C. Parman (July 29). "This species has occurred in great
abundance in Ualde and adjacent counties, The maximum abundance of cases among live stock cccurreddr4rg the latter part of June and early July, subsiding rapidly after the first week in July."
0, G. Babcock (July 29). "Very abundant throughout the month of
June. At its height the last week in June at Sonora. On the
decline since that date, and have almost disappeared at the
present time. Tr&pping and carcass burning have proved of value
at the Ex.periment Stati.on at Sonora. Only twelve cases to date
this year at the Station, and six cases by one ranuhman."
F. C. Bishopp (August 20). "The hot, dry weather during July reduced this pest to a point where it is causing practically
little damage to live stock. It is expected that a slight increase
will be experienced in the latter part of PAugust and early
September owing to more or less general August showers."
SHEP AND GOATS
NOSE FLY (Oestrus ovis L.)
New York R. C. Shannon. "Fctjd infesting sheep in Herkimer County."
Texas 0. G. Babcock (July 29). "Nose fly of sheep is still active.
Adults still appearing."
SUCKING GOAT LOUSE (Linognathus senopsis Burm.)
Texas 0. G. Babcock (July 29). "Blue or sucking goat louse very bad in
some flocks; stunted the growth of the kid crop considerably."
HAIRY RED GOAT LOUSE (Tricboectes hermsi Kellogg & Nakayama)
Texas O. G. Babcock. "Is not so numerous as last year. Was greatly
reduced in numbers since the spring shearing."
