CUTSTAIDING EN1TOMOLOGICAL FEATURES OF MAY 1921


The chinch bug situation in the Mi ssissipli Valley corn belt is still the most serious entomlogical feature reported to the Survey. The outbreak, from present information, covers the north central part of Texas; all of Okla'hoFa
( except the three northwestern counties and the southeastern prrt of the State east of a line extending from Bryant to Adair Counties); the six northwestern counties of Arkansas;
the eastern third of Kansas; southern two-thirds of :.iiisouri ( being worst in Jasper, Newton, and Scott Counties); touching south central Nebraska from Frankrlin to Thayer Counties; and southeastern Uowa from Ringgold to Louisa Counties; thence crossing southern half of illinois; narrowing to a belt across indiana, extending from Vigo to Posey Counties on the west and Allen and Wayne Counties on the East; and ending in a slight infestation in the northwestern counties of Ohio, and the southeastern border of Michigan.

The hessian flyfhas appeared in noticeable numbers in
Guilford County, North Carolina, and Barnwell County, South Carolina, In Ohio the worst fields will probably be about one-half infested, and the average infestation will probably be much lower. In Indiana the situation is more serious, the insect being abundant over the southern part of the State as high as 99 per cent of the stalks being attacked, and as far north as Lafayette infestation ranges from 50 to 90 per cent, Illinois reports the outbreak as about normal.
Missouri reports the worst outbreak since 1916 in some cases as high as 78 per cent of the stalks being attacked. In Oregon there is a normal infestation, being about a quarter less severe than last year, with from 26 to 30 per cent of the stalks attacked.

The pale western cutworm is again present in destructive numbers in Montana and Colorado. In Montana it is estimated that from 10 to 75 per cent of the small grain will be destroyed in the counties infested, and in Colorado thousands of acres are being plowed out and reseeded to a catch crop.

The western wheat-stem maggot is seriously infesting
wheat in central Montana. The last serious outbreak of this pest occurred in 1918.







The pea apis outbrea-k In the 1Aississi',1-1 Valley reported in the last Px1latin seers to I-av died out' but re-orts oj, a ver,-1y ceri-ous outbr'-tk of this insect --n Testern Oregon on vetch ( the -prfincipal hay riroD of the region ) havoc been received. The ExIpcriiueint statio.I is testinG out an a-,hidresistant variety that -:ivcs excellent promise of success.

The two clover-leaf wieevils are very much Llore nruymerous than usual in Ohio, Indiana, Illinois, New Jersey, Oregoni,
Michi!-an, loin., and Missouri.

Flea beetles attacking tobacco seed beds have appeared in serious numbers in Maryland, Vir~inia, and Kentucky.

A newly introduced scale insect is reported as attacking su~ar-cano in Louisiana.

The unusual. outbreak of the seed-omr iagj ot attacking seed potatoes, reported in the last number of the Survey Bullvt]in'P as continued', with the advance of the season, to e::te.-d0 ;icr Dwr alorg the Atlantic seaboard through New Jersey -7-o 3c Wht5and outbreaks have developed Ai~nand as far as Tir fa-irt ine, Yllinois. The most significant featuro of the oulbr ak is t*.-o coincidence of serious damage with the use 0o;.-eanio fertilizers.

A very serious outbreak of cankerworms ( both Bprin# and fall species ) has developed in southeastern W~iscons'in,, entirely -lefoiating the trees in several counties. Less serious outLlren2s are reported from Illinois-, New York,* Connecjticut, and Ohi.o.

Tent caterpillars are more numerous than usual in the New England and Middle Atlantic States.

Reports have been received of a repetition of the
serious outbreak of the achonron sphinx which occurred last year In the vineyards of Iferced County; Ca:Ufornia.

The arborvitae leftf:-m5ner is very seriously nesting the hedges qnd ornaxentA7_#pecinmens of this plant in Connecticut and on Long Island'#-New York.

Serious bagworm outbreaks are under wvay in Arkanas and Missouri.

Unusual rnubers of stable flies in Ok2.ahorrm Kansas, Vebraska, and parts of the Dakotas are reported, and a
repetition of' the serious outbreak of last year in which live stock suffered and far~i operations were suspendiet. in~ tlis rdgion is threatened.

C REAL A D FOR G E CR 0 1 iiS C T S

WHEAT

CHINCH BUG (Blissus leucopterus Say.)

West VJ E. Rumsey (May 23). "We have received no reports of chinch bug
Virginia. in West Virginia this year."

South Jo M. Eleager, county agent of Saluda County (April 1). "A very
Carolina. light infestation distributed widely over the county"

Ohio. Ho A. Gussard (Aipril 28). "We noticed chinch bu s flying freely at
Wooster today." (May 21). "There are more chinch bugs than usual scattered all over the northern half of the State ,but they are not present in sufficient numbers to be considered a menace. So far as
knovmn to me there are only two or three counties along the western border of the State that have chinch bugs in considerable numbers;
perhaps Defiance County and "!illiam County have more than other counties. I think. there are no unusual numbers at all in Erie,
Ottawa, or Lucas Counties."

Indiana. J. J. Davis (May 17). "A-parently most of the bugs have left thei:
winter quarters and are to be found in fields of small grain, especially wheat and barley. Chinch bugs are as abundant as anticipated and plans are being made for a State-wide campaign. It is
hoped to have one or more companies handling creosote to establish
supply stations in the State."

Illinois. W. P. Flint (iay 17). "The cool spring delayed the flight of chinch
bugs to the vheat. The general flight did not occur until the fist
week of May. Eggs are just being deposited, none have hatched to
date. The most serious outbreaL covers the love half of the Stte ,
the southern line extending across the center of Jackson Cou:nt to
the northeastern corner of Wabash County, anC the northern lie extending across the miCddle of Calhoun County, runnin; acios tle
southern border of Christian County, a'nd incluCing -cticall II of Crawford County. The counties in which examintions l ve been made indicate that the bugs will be fully as bad as &iticio:t & rhaps a little more abundant than ve at first thouEg-t'

Iowva. F. A. Fenton (April 2)). "I saw vteat fields i- eI tal bou. tv
which had been badly taken by clfinch bugs IEst flJ. .t the tim1e of my visit this spring (Apzil 23) the bugs vele ooi-:ig i -Lect but a
lot of then were found in the crass Jlon th a of t,> filcs.
This is the first record of chinch bus in ioL: I eout 25 :as;
at least, as far as our records 22e concerned.

Arkansas. WV. J. Baerg (May 9). "Chinch bugs in this State will probably be
confined to the northwestern corner of the State, extending south
as far as Crawford County and east as far as Carrol County. The
outbreak will probably be very slight."

Miisscuri. A. J. Burrill (March 17). "Chinch bugs unusually numerous in
Scott, Newton, and Jasper Counties. No flight seen or indicated.
In Scott County the chinch bugs were moving out of fence rowvs on
larch 15 and 16 into the corn stubble."


HJSSIAN FLY (Phytophaga destructor Say.)

.iorth Carolina- Franklin Sherman (May 2). "Damage by this insect has been reported by a correspondent from Guilford County. Crop reports to
statisticians also mention the Hessian fly, but it is evidently not
vwase than such outbreaks usually are."

South G. D. Robertson, County Agent of Barnwell County. "In February
Carolina. wheat was a failure, from the effects of Hessian fly over the entire county."

ii nnesota. C 2. Ainslie (Iday 20). "Quite a number of winter wheat fields
were looked at carefully, but I could find no trace of Hessian fly in any of them. Some dipterous (?) larvae had killed some of the
tillers but the pest, whatever it was, had left."

Ohio. Ho :. Gossard (Way 17). "Preliminary investigations regarding
Hessian fly lead us to forecast an infestation of not more than 50 per cent at Larvest time in the worst infested fields and the
average will be nuch lover than this. Some of the progeny of the
spring brood have already reached the *flaxseed" stage. Eggs were
still being laid at Sandusky, hay 17."

indiana. J. Jo Davis (May 17). Hessian fly abundant wherever observations
have been .made in the southern end of the State. The infestation
ranges up to 99 per cent of the stalks infested, and there the
majority are now in the "flaxseed" stage. At Lafayette the fly is also abundant and there are two distinct sizes of larvae, one nearly mature. These are more often to be found in the small dead tillers
Others very snall, probably not many days old, often occur in the larger stalks which have not yet been sufficiently injured to be
evident. The infestation at Lafayette ranges from 50 per cent to 90 per cent. No observations have yet been made in the northern
end of Indiana. There is every evidence that the fly will be very
abundant this coming fall."











Illinois. W. P. Flint (May 17). "Normal outbreaks occur over the entire State.
The weather for the past month has been very favorable to Hessian 1 development. The insects are now about half in the larval stage ana
half in the flaxseed stage."

Missouri. A. F. Satterthwait (Miarch 28). "Hessian fly eggs had become very
numerous on the laboratory wheat between larch 22 and March 26."
(March 28). "At Webster Groves brown puparia are now frequently
found."

H. C. Hensley (April 30). "The Hessian fly is much moro abundant than usual. Present indications are that 15 per cent of the crop
has been damaged in New Madrid County."

Leonard Haseman (May 15). "We will probably have the worst outbreak we have had since 1916. The fly is now mostly in the flaxseed stage. One 4mp1h sent to the Station showed 98 per cent infestat ion with an average of 9 larvae or flaxseeds to the infested
tiller."

Dr. Haseman included with his report a map showing the general infestation of this insect as covering most of the State, with the exception of an area in the south-central part extending from Taney
County on the southwest, Butler County on the southeast, 1ashington
County on the northeast, and Camden County on the northwest.

Oregon. M. M. Reeher and L. P. Rockwood. Tulletin and iillamette Valley.
"The outbreak is about average for the first spring brood, being about 25 per cent less than last year. The first spring flight
was completed by May 1 at ForestoGrove. About 36 per cent of the
plants and 26 per cent of the tillers were infested, while at Micinville 48 per cent of the plants and 30 per cent of the tillers were
infested. The area at Mcinville was mostly winter heat follovdng
spring and showed a high percentage of infestation for late so~n
winter wheat. Two fields at Forest Gove seeded in September during
the fall flight of the Hessian fly had 73 per cent of the plants and
59.5 per cent of the plants, respectively, infested by the first
spring brood. These fields were tinned to from 50 to 70 per cent
of a stand last fall by the fall brood of the flies."

STRAW-WOBM (Harmolita grande Riley.)

Missouri. A. F. Satterthvait (April 28). "The straw-worm is now in the pupal
stage, at least in pert, according to observations of April 25."

JOINTWOMI (Harmolita tritici Fitch.)

Illinois. W. P. Flint (May 17). "This insect is more abundant than usual in
the central part of the State; oviposit ion has taken place in the
central and southern parts of the State during the past week."











Missouri. A. F. Satterthwait (April 28), "Ovipositing in wheat on April 25
at 71ebster Groves."

PAILE IESTIEN CUTWOIEM (Porosagrotis orthogonia Morr.)

Montana. R. A. Cooley. "The pale western cutiorm is again present over the
general territory infested last year, and, if past experience can
be counted on, the losses from this insect in 1921 will be enormous.
However, in one locality in the heart of the infested legion, where since 1918 from 25 per cent to 50 per cent of the acreage seeded has
been a total loss, no damage has as yet shown up."

A. L. Strand (May 10). "About 75 per cent of the winter wheat will be totally destroyed at ?over, Teton County. Calosoea calidum has
been observed preying upon these insects. 10 per cent of the rye at Sweet Grass, Toole County, has already been destroyed, and irany wheat
fields over Hill Cunty are heavily infested and will be a total
loss."

J. WV1 Ma:nning (May 2). "Morze abundant than usual in lEns and
Clark County. Heavy losses of the crop expected."

D WV. Jones (March 4). "Damage to wheat by this insect just beginning to show up. ruch damage expected in Chouteau County."
(May 12 ). "Heavy damage to fall arf springwheat beginning to show
u in Stillwater County."

Colorado. C. P. Gillette (May 24). "This cutwcrm, wThich has attracted so much
attention in Montana, is evidently a native of Colorado and has been
somewhat more active than usual in the winter wheat belt east of the
mountains the present s-ring. Thousands of acres have been sufficiently injured t a make it necessary to plow and put in another
cr opO

WESTERN &WHET-STEA hhGGOT (Hyleavia cerealis Gillette.)

Montana. R. A. Cooley. "Severe losses to fall and spring wheat through
central Lontana have been due t o a recurrence of this insect. It
was first reported here in 1918. As the maggots axe about full
grown, destroyed fields are now being reseeded."

A. L. Strand reports this insect as almost as abundant in Cascade
County as it was in 1918, vhen many thousand acres were necessarily
reseeded. He further states that 15 per cent of the acreage in Hill
County has been destroyed by Ihis insect.

We H Jones reports fran Stillwater County that in many fields the
heat is a total loss.










PEA PHS ( !- 39-ap~

Illinois. Wj. P. Flint (May 17). "More aburdan then usual in the south'-ern
Part Of' the E'tate but the outbreak is much less SOC;{h-ilst
month, the weather having been favorable for the develommw)1 t of'
parasites, Which have destroyed from 35 to 50 per cent of the a:hids."

Oregon. A. L. Lovett (A nil 12). "The pea aphis has ap-.ea red in serious

incubation of eggs earliest laid was 16 days; the length of incubation o:
eggs at present is about 8 days; preoviposition period for moths is
averaging 3 days; the development of the codling moth is about normal fc, this section of the state; the development of the trees is far in advanc

Ohio. H. A. Gossard. "As expected some orchards near Vooster were only saved
from defoliation by spraying soon after the worms hatched. Reports of
damage by canker-worms are not coming in, hence I conclude the hatching must have been somewhat late or possibly the late frosts caught many of
the young caterpillars just after hatching, thus disposing of many of them.

PEACH TREE BOBER =eria exitiosa Say) Tew York. C-R. Crosby & Assistants report this insect as increasing in abundance in
Orleans, Wayne and Columbia Counties; about as abundant as usual in Conr(e
and Albany Counties, and less abundant in Ulster County.

Ini..1a. J. J. Davis (May 17). "This every day pest is very abundant over the State.
7e are advised that it is more abundant than usual, but this may be due tc
the fact that worming operations were somewhat suspended during the War
on account of the scarcity of labor."

LESSER PEACH TREE BORER (Aegeria pictipes G. & R.) e, York. C. R. Crosby & Assistants report this insect as very abundant in orchards
in Orleans County where brown rot is prevalent, borers infest the caxnkers.
The species was also fairly common in ::onrce County and a few were
observed in Albany and 'ayne Counties.

ZRRAPINT SCALE (Lecanium nigrofasciatum Perg.)

Ohio. H. A. Gossard. "Several reports of terrapin scale on both maple and peach
may presage more than averago abundance of this insect this season."

New York. R. P. Felt (May 13). "Is locally abundant and very injurious >to raspberry
plantings in the vicinity of ilt6n aid Marlboro, Ulster County, and this
season has already caused serious losses to the prospective berry crop.
This insect is credited with being an important factor in bringing about
the reduction in area devoted to this fruit. A very considerable percentage of the blossoms had been destroyed by May 13 and the beetles were
still active and were controlled to only a relatively slight degree by
repeated poison applications or spraying with a tobacco preparation."

P. J. Parrott (May 16). "Observed in small numbers in Ont~ario County."

Bembecia marginata Harris

0eg~n. A. L. Lovett (May 16). "Reports from Washington and Lane Counties of
serious injury to l6ganberry and raspberry plantings by the crown borer
are at hand. Probably the climatic conditions have served to seriously devitalize the plants to such an extent as to accentuate the injury-by the
borers.,,
BLACKBERRY

ROSE CUROULIO (Rhynchites bicolor Fab.) go. A. L. Lovett (May 12). "The rose curculio is appearing on the buds of
small fruits, principally blackberries in the vicinity of Portland. The
beetles injure the blossom buds by feeding and oviposition punctures. The buds wilt and never open. The same injury occurred in 1912 and 1913 but
has been almost negligible since that time.

PINK BOLLWORM (Pectinerhora usvaTiella Saund,)


At the conference relating to the pink bollworm situation, held
at Washington, May 16, 1921, .ttended by representatives of the States of Virginia, North Carolina, South Carclina, Georgia, Florida, Alabama, ississip-i, Louisiana, Texas, Arkansas, Oklahom;, New Mexico, Arizona, and California, the following rep rt as unantizously adopted as embodying the opinions of the conference:
(1) We indorse and coz.end the Policies of the Federal Horticultural Board in. dealing with the pink bcllworm situation in the United States. We wish, furthermore, to express cur approval particularly of the work of Dr. W. D. Hunter, who has been in direct charge of the field work of the infested States; his energy, persistence, and tact in
dealing with an unusually difficult situation a.re especially to be commended. To his efforts and to those of the proper State authorities who have worked in4cooperation with him, especially in Texas and Louisiana, the other cotton-growing States feel deeply indebted that this cotton pest has not spread more widely since 1917.
(2) It is clear to the conference that the only practicable method of eradicating the pink brll;orm is by continued prohibition of the growth of cotton in irfes ted districts for a period of years. The feasibility of extermination work where conducted according to the methods and maintained for the period of time reco::ended by the entomologists of the Cotton States and approved by the Federal Horticultural Board is completely demonstrated -n the Hearne district, where a nonctton zone has been -aintained since the fall of 1917 and intensive scouting each year thereafter has failed to show any recurrence of the infestation. FutLhhermore, it is apparent in the Trinity Bay district that the maintenance of a noncotton zone for one year only is not long enough to accoaplish extermination.
(3) The conference believes that there is now a possibility of
exterminating the pink bollworm but that this opportunity is one that must be taken proLpt advantage of. On the other hand, we feel that the continuance of the infestation in any areas under a regulated system is fraught with grave danger to the entire cotton industry. Therefore, we believe that the present establishment of regulated are-s in west Texas and New Mexico should be considered only as a temporary -rrangement, to be conditdbdd onyso long as may be necessary for appropriations to be made to maintain this district as a noncotton zone. In the meantime, also, we would recoi.end that efforts be made to secure the cooperation of the Mexican authorities in maintaining a noncotton zone on the Mexican side of the border. In order to provide further safeguard against the introduction of infestation, we believe that the Imagration Service along the Mexican border should be so strengthened as to secure the movement of all laborers coming from Mexicc into the United States through the proper points of enory where addquat6 inspections may be maintained.






-62



(4) In dealing with the pink billworta situation, adequate provision should be made in State laws for a technical commission, which should be vested with 'lull authority in establishing the fact of infestation, as well as in exercising wide discretion in relation to the fixing of the limits of any areas which m~ay be placed in noncotton zones or regulated zones, such zones to be continued in force automzatically until changed by the act of the commission.
(5) With reference to States bordering on Mexico, the conference believes that action should be based upon ifefstation conditions prevailing on the Mexican as well as on the Amnerican side, in such action both Federal and State authorities should cooperate,
(6) We beldpve that inasmuch as the work of eradication is un~Xdertaken for the benefit of the country at large, as well as for the direct benefit of the States wherein infestation may be found, that tha'%funds utilized in maintaining noncotton zones should be supplied jointly by the State and Federal Governments, in.accordance with precedents already established in the case of the work against tuberculosis and the foot and mouth disease of cattle.
(?* Wfe. hereby express our appreciation of the present attitude of
the citizens of Louisiana and Texas in favor of extermination work, as reported by their representatives in this conference. We are gratiafied with the assurance we have here received that it is proposed, through a special session of the Texas Legislatures to be held in July, 1921, to strengthen and make fully effective the eradication work now under Way, or to be hereafter instituted in that State.

P. J. Parrott (April 25). "Flies observed in considerable numbers in cabbage seed teds !Jay 16. Egg laying not extensive; the larvae are
now hatching."

New Jersey T. J. Headlee (April 27). "Some damage by the cabbage maggot attack
ing early cabbage."

Indiana J. J. Davis (May 5). On May 2 1 was at Hammond and there found cabbage maggot eggs on every plant examined, and in many cases 15 or more eggs to aplant. In this connection it is interesting to know
that last year there was practically no damage by the cabbage maggot
in that section.of the State."

(May 17). "For the past 15 years the cabbage maggot has been a regular pest in northwestern Indiana; last year, however, it
was conspicuous by its absence. A second visit to Hammond, May 14, showed a heavy infestation of small maggots in cabbage, cauliflower,
and radish, and dozens of eggs about every cabbage or cauliflower
plant in the favored areas."

ASPARAGUS

ASPARAGUS BEETLE (Crioceris asparagi L.)

New York J. D. Detwiler (May 20). "Beetles fairly numerous, have been laying
eggs for the past two weeks at Ithaca."

TDelaware C. 0. Houghton (May 9). "M1ore numerous than usual at Newark. With
this species has appeared Crioceris 12-punctata L., but much less
numerous than the asparagus beetle."

Ohio H. A. Gossard (May 12). "Beetles were observed at arietta on May 1:."

Michigan R. H. Pettit (May 17). "More abundant than usual, damage being quite
serious. Have observed hymenopterous egg parasites attacking the eggs
of this beetle."

BEAN

BROWN COLASPIS (Colaspis brunnea Fab.,)

Florid E. Frierson (May 12). "Noticed for the first time today at Elfers;
about 10 percent of the beans were damaged by actual count. The variety flavida is the one present."

MEXICAN BEAN BEETLE (Epilachna corrupta Muls.)

Alabama W. E. Hinds (May !0). "Continued to emerge in large numbers from
hibernation, and even the earliest planted table beans are now
threatened with extremely serious injury. Cold weather has delayed
the crop and favored the increased dwn;ge flem this species."











F. H. Chittenden, Bureau of Entomology. "Investigations of the distribution of the Mexican bean beetle show that it is continuing to
spread. It has been reported under dates of May 30 and June I as follows:

Tennessee 11 miles north of Chattanooga, and from McDonald in Bradley County, to
Tucker Springs in the same county.

Georgia Dade County (Rising Fawn, Trenton, Sulphur Springs), Chattooga county
(Lyerly and Holland), Floyd county (Gammon), and Walker County (Flintstone, Highpoint, Cooper Heights, Cassandra, Shaw, and Lafayette).

Alabama Cherokee County (Pleasant Springs), Calhoun County (Piedmont, Anniston),
Clebourne County (M1uscadine, about 2 miles from the Georgia line, showing a spread of about 60 miles due east).

It is evident from the information already obtained that the bean
beetle will spread much more rapidly than was at first believed/ There is indeed reason to believe that the extensive spread could only be accomplished by strong migration immediately before hibernation last fall.
This habit is characteristic of other Coccinellidae and may be reasonably expected with the Mexican bean beetle and other Epilachna."

CUCUMBERS AND MELONS

STRIPED CUCUMBER BEETLE (Diabrotica vittata Fab.)

Alabama 3. :. Davis (May 10). "Made their conspicuous appearance at Lafayette

Florida :eff Chaff in and assistants report that this insect was first noticed
on May 1 in Orange County; by May 4, it was doing considerable damage
over the entire county; and by May 9, at least 15 per cent of the watermelons that had not been sprayed were seriously damaged. At
Arcadia this insect was reported ac being more abundant and doing many times as much damage as usual in watermelon fields located near citrus
groves by April 18; and was much more abundant than usual in Pasco
County by April 19.

New York E. P. Felt. "Strawberry weevil adults were observed in small numbers in Saratoga County on May 18."

C. R. Crosby and assistants report that they were quite numerous and
doing considerable damage in Ulster County by April 27. In one
planting about 10 per cent of the blossoms had been already cut off.
By May 7 it was noticeable that serious injury was confined to the
variety William Belts; varieties Sample, Schofield, and Bubach are only slightly injured. Slight damage was also reported from Orleans
County, while a more serious outbreak developed in Columbia County;
here one dusting was applied on April 22 and another on April 30.
The two treatments held the pest in check ffom the report received
on May 7; here again, the William Belts variety seems to be the
worst infested.

in Indiana and is a very serious pest."

H. F. Dietz ( May 17) Chrysanthemum midge is getting widely
scattered -though it does not seem to be a s destructive as in the past, probably our mild winter was favorable to its
rapid multiplication. There is at present a decided shortage of chrysantheciun stock in Indianapolis, which means that lots
of florists will have to buy plants and if they are not careful
will get midges with them.

THRIPS ( H1eliothrips femoralis Reut.?) Indiana. H.S,, Dietz ( May 17) Thrips have been very abundant on

Stable fly ( Stomoxys calcitrans L.)

Office of Southern Field Crop Insect Invostigation: Attention must
be given to the stacking of straw during threshing if the terrible
outbreak of stable flies of last year is not to be repeated this season.
Last year's losses are well remembered by the farmers and stochmen of Oklahoma, Kansas- Nebraska, and parts of the Daotas. Hcvy r.ins at
threshing time combined with loose piling of the straw was res :oniblc.
Plowing wqs practically abandoned in some sections, and tractors were
resorted to in many instance. as the horses could not withstand the
overwhelming hordes of flies. Cattle suffered heavily, flesh being
greatly reduced and milk flow cut tv:entywfive to fifty per cent, in
some c!oes. Death loss was also heavy- animals weakened through blood
loss and worry fell ready prey to certain diseases and others were
said to be actually made sick by the flies themselves. The field men of the Bureau of Entomology state that these blood-sucking flies were present in unusual numbers in June. Uith many old straw stacks
still in the fields .nd the usual careless piling of straw at
threshing time and some heavy suner rains these flies will develop
into veritable hordes late in the summer.
