OUTSTANDING TCO:OL.?ICAL FEATU-TJ S IN THI .'TTD STm.TES C.R MAY, 924

Th3 weather over the Eastcrn and "t-ntral States has been verv unusual,
the spring; being very back-:ard and precipitation bein2 much in excess of
normAl.
Chinch bu development has been materially reduced over the greater
part of the bolt, but present indications are that serious infestations will
cover southwestern, w"est-central, and central :,lissouri, eastern Kansas,
southern 1ebraska, southeastern Iowa, and northeastern, central, and south-
centrzl Cklahomna, with possible tad outbreaks in southern Illinois and Indi:.na.

A serious grasshopper outbreak covers entire east-central Texas and
sout'."er -i OCi oma.

The Hessian fly infestation is reported as v7ery light in Ohio and Iowa,
with conditions about the same as last month in Missouri and Nebraska. In
Kansas the conditions resulting in severe d.nse last fall have bcun apparently
relieved by the dry b-c:k!-ard spring which prevailed in this region. In
Oklahoma a few counties report serious infestation.

The arm, c,:t'srr. is occurring in a severe cutbrenc in the Judith River
Bsin in Montana, and gencr:l cut'-orr damage is reported from the lo'er Mississipp.
Valley region and Texas.

Unusual abundance of white grubs and heavy fli.-.ts of beetles are re-
ported from Iowa, Missci"i, and CKansas.

The anomala Anomala orientals "7'torh., which w.7as introduced into
Connecticut several years ;.-o and reported in Volumes 1 and 2 of this Palletin,
is apparently increasing. On several lawns at '.;st-ille larvae average 60 per
square foot. It will be recalled that this pst oc ;as:-n ..d much concern among
the sugar planters in Hawaii several ye_rs a;o amd ':as finally controlled by
an intn aucod scoliid wasp.

The corn uarw-orra has destroyed as high as 75 por cent of the early
beans in parts of Mississippi.

The Colorado potato beetle is more troublesome than usual over the
extreme southern States, reports of serious damage comirg from Georgia, Florida,
Mississippi, and Texas.

A very remarkca'ble flight of the painted lI-d- butterfly is recorded
from California, estimates running into the billions of individuals. This
has been followed by a serious outbreak of caterpillars r'hich are attacking
garden plants of all kinds.
A very remarkable flight of the painted lady butterfly is recorded from
California,estimates running into the billions of individuals. This has been
followed by a serious outbreak of caterpillars rhich are attacking garden plants
of all kinds. -5








The apple aphid.n in general seems to be very -,uch belo7 normal in abundance
in the Eastern States, whereas the apple tent caterpillar is unusually abundant
over the ITc,17 England, Middile Atlantic, and East-Central StLies.

Pear thrips abund ::nze is much bclo"' normal but the pear psylla is seriously
abundant in the fruit belt of New York and is also abundant in e1167 England.

i serious outbreak of a heretofore unimportant case-bearer, Coloophor7a
scram,-nta Heinrich,has developed on cherry in one locality in California; and
a native wemvil, _nmomhua sordidus Horn, has become a serious currant pest
in this Sta.to.

A\n aphid, as yet not definitely determined, is attracting considerable
attention in Florida as a citrus pest.

An interesting note comes from P-orto Rico, Trhere it is found that one
of the cotton stc-iners is attracted in large numbers to pieces of the silk of
Ceiba, suggesting a possible remedial r'esour'e for the control of this pest.

The practice of using the same land for seed bkds of tobacco year after
year has resulted in ra-ther serious dirmze in parts of Tennessee by the larvae
of the ereen Ji-e beetle, vhich scorn to be attracted by the litter used to
protect these seed beds.

Both the gipsy :noth and brown-tail moth seem to be somewhat less numerous
over the old infested territory than they were last year.

Two cases of Rocky l*ovfntain spotted fever have occurred in northern
Ccloradc this spring.

OUTSTJ7I:.TG 0T, GLOC-ICL ? :.--.-!J75S 'R CAcTDi. FORC !.'AY,1924

Stem-::others of the back chor-- aphid occurred in large numbers in
April on the opening buds of sweet cherries in the niagora Peninsula, Ontario,
and judging from their n-r-.bers in the orchards at present some trouble may be
expected.
The Zu-or.c' red mite is widely distributed in Nova Scotia. It has
beer, note from time to tim in the past in various xarts of the ,jnapolis
Valley, I. S.

The raspberry cane mg:ot ,Phorbia rub jv.ra Coq, continues to be a nest
of considerable :lrurtance to logan berries .an raspberries at Victoria, B. C.
Adults commenced to emerge on March 22 this year, the earliest date on record.

The rose scale, Aac'sis rose 3ouche,wvhich has occurred in the lower
Fraser Valley of British Columbia in raspberry pl:ntatians for meny years, is
now reported as causing considerable alarm amon l sm-ll fruit growers in that
locality.

The green apple 4,\hid is more ab-undant on apple trees this season in
southwestern On'Gc-r.o than it has been for several ye'Trs.

The leaf miner Gracilria elotella Busck has been very conspicuous on
the -un ood of cpcio trees along the shores of L-,ke Ontario from Toronto to
the Tiogara River. The health of thD trees, however, apparently has not been
affected.

E. E. Fchioll (May 17): We have just had a request from Carter
County for irmediate assistance in putting on a grasshopper cam-
paign. The report stated that grasshoppers are present by the
raillions ard arc just large enough now to travel and become very
destructive. Control work will be started early next week.
0
F. L. T-hors (:'ay 21): The most imoortant feature of insect
actrvi'y is the grasshopcr outbreak which is now in the fourth
weeh of its occurrence and covers nearly the entire east-central
portion of thle State. A great deal of poisoned bait is being
distributed in the various counties.

F. C. Bishop (!'ay 24): Grasshoppers were reported as appe-ring
in considerable numbers in the bottom lands in Dallas County on
Iay 20 The young hoppers were doing some d-irage- to young cotton,
which is riarkedly later than normal this year.

E. J. Newcomer (Hay 20): An outbreak of grasshoppers has been
reported in Okanogan County. This is similar to previous out-
breaks in that section but may be more serious, owing to increased
plantings of fruit trees.


CUTWOKS (No ctuidae)


Mississippi


Texas


SMont ana


H. W. Allen (.'ay 23): Nearly full-grown caterpillars are generally
distributed on covers, cabbage, bean, potato, etc., without caus-
ing much apparent derag. They are most abundant under heavy
growth of clover in darp soil, where 30 or more to a square yard
can be readily found.

L. H'.seran (l"ay 22): Sever.l species are very abundant, though no
comenlaints of serious damage have cone in as yet.

F. C. Bishop (April 15): Cutwonrs are causing considerable loss
to gardens in Dallas and vicinity, being :sp-:cially injurious to
tomatoes and other plants recently set out.

W. C. Cooke (May 12): We have reports of a rather severe outbreak
of the ar"ry cutwvorm, Chprisagrotis auxiliaris, in the Judith Basin
district in central Montana. Several hundred acres have been
affected to date and it has been impossible for us to check up on
the abundance of the larvae. T'.e species scenm to be about two
weeks later this season than usual, which is rather exceptional
as the spring season has been slightly earlier than usual.

CORRECTION:


C. 0. HouLhton (iJy 6): An enornro'-s swarm of PhylloDha7a tristis
Fab. was ooserved in flight on the evening of May 6 at McClellands-
ville. Mr. Seidel, the observer, reported that there were millions
of them and that they weighted down the raspberry bushes upon which
they settled. He said that zhey could be gathered by the handful
anyvlher. upon a large area of the bushes. No injury "was observed,
and they were all gone the next morning. (This species is known
to feed especially upon oakc.,)

H. E. Jac ues (iMay 9): Fror all indications Brood A of the white
grubs threazens to be fully as serior s in its damage in southeastern
Iowa this year as it was in 1921. It would seen from the early
inquiries and observations tnit I have trade that it ray be extending
itcs area of inf station west rd. Gruos have been showing up
abunde'ntly in the spring plowing.

L. Hasenan (May 22): WJhite -ruos are very abundant and a heavy
crop of adult beetles cmre cut tne first half of the month.

J. W. !'cColloch (May 'C'): IWhite grubs have killed out a large area
of blue-grass sod in a cer.-tery at Alma.

J. J. Davis (May 24): On ra:e 50, Volume 4, No. 2, of the Insect

T. J. Head lee (Ma- 1): I ar sending sorne wir(woTrs (Iel ,notus sp.)
which are troublesc-e in cultivatd lands. These lands are in the
hands of nrarket gardeners ai.d Lre more or less constantly under
cult ivation.

M. H. Swnk (April 2C-T'ay 15): Irn spite of the cool, backward
spri'i wirewonns hav- not been ir u-h co1r-lained of to date in the
eirliest planted corn. Such trouble rrty develop later, however.



HIESIAN FLY (7.1yt' v -i d structor Say)

T. H. Parks (May 20): 1rheat in the central and southern counties
is almost free from the Hessian fly. Only with difficulty could
-, .s be found. Early sewed veat in 3 northeastern counties had
a medium inf station K ay 1. Kuch 'v-rterki]lirg cf wheat has
occurred except in north.-.estcrn counmi>s.

Carl J. Drake (May 26): Hessian fly is on the decrease in the
State. The campaign of 1923 owes its success to the cooperating
farmers who put off drilling until the fly-free- date was predicted.



























Missouri




Nebraska





Kansas











Oklahora


Illinois


Of the 52 Counties coo-orating in 1923 over 90 per cent of the
farmers in d4-rs, Appanoose, Boone, Carroll, Cass, Cedar, Dallas,
Des Yoines, Fremont, Guthrie, Henry, Jasper, Lucas, Mills, Monroe,
Mocntgomery, Page, Polk, Pottawattamie, Taylor, 17apello, Tarren,and
Woodoury put off s.edingf. until after the fly-free date was estab-
lished. The flaxseed, count enabled us to predict accurately the
fly-free date.
The spring brood of flies be-an to emerge in the early seeded
fields in April. Fred Butcher, Extension Entomologist, is con-
ducting a Hessian fl.y observation station at Errerson, Yills County,
in order to determine the period of emergence of the spring brood.
The dry and cold weather this spring killed a large number of flies
in the flaxseediz. The larvae pupated successfully but the adults
died before oreak.ih? through the flaxseeda The percentage of
dead fornms is very large but only a smal ,er cent of the larvae are
parasitized.

L. hasemian (May 22): The Hessian fly situation is not materially
changed from the earlier report. Most farmers are centering their
attention oa the chinch bug in wheat, though we will have some
Hessian fly damage undoubtedly.

M. h. Swenk (April 20-May 15): During the period covered by this
report adults of the Hessian fly have been emerging from the over-
wintered flaxseeds. Examination of material on May 2 from Dodge
County and on M.ay 5 from Saunders County indicated that the great
bulk of the flies had not as yet emerged.

J. W. McColloch (TNay 2): This report represents the damage to
wheat last fall; 9,761,085 acres were sown to wheat in the fall of
1923 and 633,613 acres, or 6.5 ner cent, sh'.- fly damage. Of the
633,613 acres shorting injury 128,481 acres, or 20.3 per cent, will
be a complete failure. (Mi"ay 21): The Hessian fly has not proved
as serious this spring as was anticipated. This is probably due
to the dry, cold spring which is holding everything back. The
principle damage so far this spring has been reported in the eastern
third of the StaTe. No dc.mage has been reported from northwestern
Kansas where the fly was so abundant last fall.

E. E. School (May 17): In the counties of Ottawa and Craig a
number of wheat fields show such heavy Hessian fly damage that they
will be plowed under and, at the suggestion of the county agent, such
crops as cowpeas and soy beans will be planted.

CHINCHI BUG (Blissus leucooterus Say)

V1. P. Flint: The weather of the past month has been very cool and
but little e.-o layi;.g has taken place. The rainfall has been about
normal tut on the whole weather conditions have been unfavorable to
this insect. They have not been sufficiently adverse to cause any
great reduction in the number of'chinch bugs in fields.

Carl j. Drake (Iay 26): The chinch I..-, occurs in alarn inu numbers
in Clarke, Lucas, Monroe, "-rpello, Jefferson, Henry, Des jloines,
Decatur, XVayne, Appannoose, Davis, Van Buren, and Lee Counties.
Most of the adults seem to have passed through the winter success-
fully.

L. Haseman r-Vay 22): Chinch bugs are particularly serious through-
out southwest, vest-cent:ral, and central Fissouri. A conference
called for the 24th at Kansas City will deal largely with out surrer
program in this and surrouvning States for chinch bug control. If
the weather continues favorable we are certain to have a big summer
chinch "cg problem.

\. H. Swenk (April 20-May 15): During the second -.veek in ray the
chinch bug was reported as having put in an appearance in abundance
in tne small grain fields of Pawnee and southern Gage Cc,.t-ies.

J. WV. McColloch (lay 21): Chinch bugs are no%. abundant in fields
of small grain in the eastern hilf of Kansas. Some farmers report
crors being severely injured. The weather has been very dry and
temperatures much below normal.

E. E. Scholl (Uay i7): Chinch bugs are ncr.'oer'inning to do a great
deal of damage in the northeastern part of the State and are just
beginning to get active in the south-central part also. A number
of chinch bug ees were found but the hazching is very slow on
account of the cold weather.

J. today which had 15 per cent of the tillers infested.

GRFAT-PLPIi'S FILSE "'TRP"0RT (Eleodes o-aca Say)

H. C. Severin (Mlay 14): Our spring has been extremely late and,
therefore, the injury by Eleodes, probably E. oraca, will continue
for several weeks at Groton.


LEPFHOPPFRS (Jassidae)


F. C. Bishopp: During the latter part of archh and the first half
of April leafhoppers were reported from several localities in Dallas
and Collin Counties as damaging winter grains. In some fields the
nymphs are present in great swarms and all plants are showing the
effect of their attack, many being completely killed. Some farmers
plowed up their grain, fearing that it would not make a satisfactory
crop.

J. F. Adams (May 20): Aphids were observed at Seaiord Arril 30.
At the present tire, 3 weeks later, they have apparently increased
but little in numbers. The cold, wet weather has undoubtedly been
an important factor.

Geo. F. Knowlton (May 27): Indications are that this will be a

most of the sweet peas that were being raised for seed purposes.


CUCUMBERS

STRIPFD CUCUPBER ?FETLE (Diaorotica vittata Fab.)


Massachusetts









Mississippi


A. I. Bourne (Way 23): A report by Prof. Koon of injury by the
cucumber beetle to cucumboers in greenhouses in Baldwinsville, which
is in northern Vrorcester County, is received. The particular
damage is caused by the wilt following the attacks of the beetles.
It appears that squashes and cucumbers were gro"n near the house
last year, and in all probability the beetles hibernated in the
greenhouses and were then at hand to attack the young cucumbers
early in April. His estimate of the losses due to the vwilt was
25 per cent of the crop.

J. E. McEvilly (May 7): Seedling plants have been attacked by the
larvae cf this nest at Summit. Adults are appearing in great
numbers. Nicotine dusting and spraying are being practiced.

H. "T. Allen (May 23): In twc hcme gardens 3 miles apart in
Oktibbeha County no adults have been seen. In one containing
squash, cucumber, and cantaloupe, in -rhich a very heavy infesta-
tion developed last season, not a single beetle has been found this
season thoiu-h the plants have been present more than a month.

CO'ON RED SPIDER (etray hus teareius5 L,)

husetts A. I. Bourne (May 23): The cormon red spider on cucumbers has been
reported as doing considerable damage in certain of the greenhouses
in the 1farket Gardenr district around Boston. Specific estimate of
damage to one house in Mansfield places the figure at 25 per cent
of the crop. In another house in 7oburn this insect is credited
with causing approximately a 10 per cent loss.

ROOT-Yr.7T "-LATODE (Het rc ra radIti c 1a Greef-Hueller)

husetts A. I. Bourne (iay 23): The root-knot nematode has been reported to
this office by Prof. Koon, in charge of the Market Garden Field
Station, who has found it to be rather prevalent in greenhouses
throughout the suburban districts of Boston. A conservative es-
timate places tie dam-age to cucumbers at from 5 to 10 per cent, in
different ranges.

RHUBARB

P;cvT:D LADY BUTTZRFLY (fnessa cardiL.)

E. A. hcGregor: Continuing from April 11 to 13, inclusive, there
was a rcra'isable migration of this butterfly. All through the day
tr-n'. waS a continual f light of these insects. HRo Yhly it was
estinia+.ed that there were an average of about 300 rutterf lies per
acre at a given moment. The flight direction appeared to be from
the southeast to the northwest, and it would seem -that the source
of lhe migration was either the foothills of the Sierras or the
Sierras proper.
In travelling, the flight was not characteristic of butterflies
in general, .i+ was of a more steady and purposeful nature. During
calm intervals the I light took place on an avera-e of perhaps 10 or
20 feet altitude, but during periods of windiness the butterflies
iiew very close to the ground. T.-are appeared to be no attcrpt
toward pairing and the individuals flew well separated -- possibly
10 feet anart on an average. It wos very notic&abie tiat they all
puirued their flight in the same direction. It was rarely that
individuals :!ere seenr. to alight cn vegetation, but this they did
c.t ziri'S .
The above fl'iFht occurred during the wanrest period yet exper-
ienced this season, temperature maximurms ranging from 80 to 2o F.
The temperature suddenly dropped late on the afternoon of 'the 13-Ih,
accormpanied by a chilly wind, and the flight as suddenly terminald.
On the 15th the temperature rose again but a gusty wind occurred so
that only a very few individuals could be seen migrating.
An attempt to estimate the number of individuals corprisir.- this
3-day migration is here presented. The flight was established to
be equally dense at Sunland, Porterville, Strathmrore, Lindsay,
Exeter, Visalia, VWood lake, and Lemon Cove. This shows the flight
to have been at least 40 miles in width( (it no doubt v-as much riderr.
The daily duration of the emigration was at least 12 hours, or a
total ior the three days of 36 flight hours for aily ivren point.
Now the rate of travel was estimated at about 12 .-iles per hour,
which would give to tne fli,..t a total dispersion ln;th of 432
miles for the 3 days. 7Tithin such a zone (40 \ il:s '.ide by 432
riles incr-.) is contained about 17,2O square mi3es or 11,059,200
acres. 7ith an estimated occurrence of about 300 butterflies per
acre, it is readily computed th a at least 3 C0)O ,(OC0 ,CCO had r.assed
in the 40-mile-wide zone between Sunl-u.d and Lenon Cove.
if more data were availaole regarding the width of the flight,
it undoubtedly could be shown that the population of this interest-
ing migratory flight much exceeded the above eotir-ate.

R. E. Campbell (May 10): Following an extended and heavy northerly
flight of the painted lady outterfly the hairy caterpillars began
to appear on weeds, mostly malva, thistle, and nettles. As these





- 71 -


were consumed, died, or w;,ere plov ed up, the caterpilars began to
migrate to other vegetation, including .-arden plants of all kinds,
out particularly lettuce, radishes, potatoes, and beets, as well
as some flowers. In some cases following the plowing of orchards,
t:ie foliage of -ou.-.F orange trees was attacked. At one place in
'entuga Coiun.-y the cateripillars were so numerous th-at they assured
the annr yworm haoit, and thousands began migrating, necessitating
the construction of trench barriers to protect near-by crops.
Great quantities of worms were killed by running an automobile with
the wheels on one side in the bottom of the furrow..
The ilight and succeeding infestation covered the entire area of
southern California as far north as San Luis Obisro. Newspapers
carried reports of flights so heavy that motorists were compelled
to stop their cars and brush the butterflies off tneir radiators.

to a leaf; in some cases as many as 30 or 40. These sirall leaves,

The county agent for Franklin County reported that the San Jose
scale is more prevalent throughout that general section than he has
seen it Ifor several -e -rs.

C. R. Crosby and assistants: FReoorts from the eastern part of the

ate that the San Jose scale is moderately abundant throughout the
Sta:e, thc^L not serious in well-cre:1-for orchards.

Franklin Sherm.an (!:ay 26): Beginning with 1915 the complaints were
far less than they had been previously and this continued to the ex-
tent that from 1S18 to 193 the complaints were very few. Even at
present it is still at lor ebb in number of complaints; but some of
the reports received, and field consultations and inspections also,
indicate tha- the San Jose scale is staging somewhat of a "core-back";
not so severe perhaps as seems to oe indicated in some other States,
but noticeable.

charge cf this orchard, tells ire he sprayed on Friday, at which time
there were about five flea-beetles to each bud, with arsenate of
lead, 2 pounds to 50 gallons of 'water, using 300 pounds pressure
and a -un which distributed the spray liberally. His success was
very great indeed. On Sunday when we examined these trees there
were very few beetles present; enough of course to require another
spray, perhaps more after a time, but over 99 per cent certainly
must have been killed. The flea-w-eevil in this orchard confines
its work almost altogeTher to Spies. Other varieties close by

C. 0. Houghton (Way 14): P Loth, which I have identified as this
species, was taken on the eveiir-,. of May 14 as it was hovering about
a small peach tree. This is the first I have seen of this species
here, but I now believe that considerable of the injury to peach
teirinais last year, and which was attributed to Anarsia, was really
by this species.

SAN JOSE SCILE (_5_ii ictus pern:j ciosus Comrnst .)

Oliver I. Sr:apr ('ay 16): Cold weather and s-praying killed out the

which did srv-ive the winter have not yet reached maturity, and
cornsequently no breeding has taokn place yet this year. The San

PEACH BORFR (Aegeria exitiosa Say)

Georgia Oliver I. Snapp (May 15): Due in all probability to the large arnoun
of paradichlorobenzene used in Georgia during the last three years
the general peach borer irlestation has been greatly reduced in the
State.

SHOT-HOLE BORER (S coltus ruzulosus Ratz.)

Georgia V1. C. iHcCarrell (April 22): First specimens sent to my office of
this insect on this date attacking peach.

Oliver I. Snapp >'ay 16): Developments since last report show thqt
the curculio instation at the present time in the Georgia Peach
pelt is apparently lighter than at any tine since 1918. The late,
cold spring caused the beetles to remain in hibernation later than
usual, and consequently they care out in greater numbers during a
short period the mrriddle of April than was recorded for any period
during the 1923 season; however, the peach "drop" examinations show
that inrth majority of orchards the curculic infestation at the
pres-.t time is only about one-half as heavy as it was a year ago,
when it was lighter than it has oeen for years. This remarkable
reduction in the infestation has resulted from the vigorous curculio
suppression c,:moaign that has oeen waged in Georgia since 1920.

Mississippi J. E. McEvilly (]ay 7): Work of this pest ?s very noticeable in

Franklin Sherman (May 26): First specimens out of hibernation
were captured April 15, two specimens in different counties in
warmer region of the State. The next similar finding was April 25.
These three findings were before cotton was up; one was caught on
the back of a man in a field planting cotton, the other two were
taken from peach trees incidental to curculio work.
The first specimen found on young cotton was captured "on or
about May lP" in the warnmer part of our State (Scotland County)
and was mailed May 20, with two others, all three being alive
when it was received.
The above dates (mid-April) for first findings out of hibernation
are approximately the same as in 1923, but finding weevils on
young cotton on May 14 is about a week earlier than the first
similar record in 1923.

J6 E, McEvilly (May 8): Several thousand pounds of calcium arsenate
and dusting equipment bought bybthe farmers in this section to
combat ravages of the weevil this season.

A CCTTON ST.-JrM= (Dysdercus andreae L.)

Arthur H. Rosenfeld (May 18): I made rather an interesting
observation on the 12th inst. at Hacienda Isidore, near Santa Isabel,








on the South Coast, Isidoro being one of the outlying colonies
of the Central Azuirre. On a previous trip about a month ago
Mr, Wolcott and I had noticed the cotton stainer, or "union"
as it is called here, quite abundant on volunteer cotton trees
in that section and on this trip I noticed the adults clustered
in large numbers on small pieces of the silk of the Caiba on the
ground, at times there being from forty to a hundred insects on
a small piece of fiber. Incidentally, the chic,:ens were busily
proving their interest in this particular insect. Mr. Wolcott
tells ms that he has never noticed these stainers on this Ceiba
fiber before, and therefore the observation may have some interest,
as one of the Trinidad publications some time ago recorrend.-d
the use of bunches of this fiber around cotton plants as an attract-
ant for the Dysdercus the species found at Isidoro was andreae
Linnaeus, by the way 7hich could afterwards be collected and
destroyed by dropping them into kerosene or fire.

CARABID BEETLE (Anisotarsus nitidinennis,Lec. det.

Texas F. C, Bishopp (May 24): This carabid beetle "--s found in great
numbers in cotton fields in the vicinity of Dallas during the
middle of 'lay. Dozens of the beetles were often found about an
inch under the soil i-.iedi-itely surrounding the germinating
cotton, and they appeared to be gnawing on the cotyledons as they
unfolded. The stand of cotton in certain fields was seriously
dar-nged.

Tennessee A, C. Morg-n (April 29): The larvae of the grubworm beetle is
quite injurious at present on tobacco beds which were sown in the
old seed beds of last year. It is becoming more customary to
sow beds in the same situation year after year and protect them
during the summer with a covering of manure, straw, or tobacco
stalks. This covering has proven attractive to the beetle for
the deposition of its e~gs and remedial measures have been necessary
Apon a large number of these second-year beds.

both in orchLrds and along the hi4'-"mys.
In Niddlesex County the pest in orchards seems to be practically

HO F. Dietz (M'.-y 23): s a general obser-vation on various
species of plant-lice attacking ornajental planUs, I would say
that these are far less abundant than I have seen them at the
same time of the year for the past five years,

". R'T MITE ( Linonvcs-us bacoti Hirst)

Texas F. C. Bishopp (May 24): This mite has been causing some annoyance
in offices and stores in Dallas during this spring. It is
expected that the c-:-p-.i--n which is now being staged against
rats will effect a largee degree of control.

CATTLE

SCE-IiYSORM (Chrysorya macellaria Fab.)

Tcxas F, C. Bishop (April 9): The first specimens of screwworm flies
were observed in Dallas on this date. They constituted a very
small percentage of the fly p:-l:l Ltion about the packing houses.
(April 17): There ha.s been a very decided increase in the
number of screwworm flies since the last date when they reached
approximately S per cent of the total catch in tr-ps. (May 24):
Screwo:rm flies increased in abundance considerably throughout the
month of Tay, despite the comparatively cool, dry weather. Practi-
cally no cases bf screwworm infestations of livestock were
reported, however, up to this date.

D. C. Parmran (May 23): The adult fly has increased very little
during the month at Uvalde, but cases of worms have increased
rapidly during the last ew days. Goats and sheep; 13 cases per
1,C000; loss during the month approximately 8 head per 1,000,
mostly kids and lambs. Cattle and horses; in canyons, 3 cases
per 1,000; in lower country, 47 cases per 1,000. Loss in calves
SO per 1,000, all calves infested.
HORTFLY (H Cnatobia irritans L.)


Texas F* C. Bishopp (April 10): Hornflies began to appear in annoying
numbers about this date. (May 24): While hornflies have increased
considerably during. May, they are not as abundant as usual at
this time of the year, probably o-in7 to the comparatively dry
spring which has been experienced in the vicinity of Dallas,

D. C. Parman (!ay 23): The horn fly has increased to some
extent in all of the territory during the month except in the
strip of territory about 15 miles wide south of town in which
the heavy hail fell in April and a very heavy rain on Iy 22.
It is rare to see an adult; other places from 50 to 2,000 flies
on cattle.

OX 7AR3LE (Hypoderua lineatum DeVill.)

GEIERALL F. C, Bishopp: Mr. W, E. Dove reports the grubs of this species
to be maturing and dropping at v.-rious points in North D-T:ot-,
South Dakota, and M'ontana. A greater number had left the cattle









in eastern Montana than in the Red. PRiver Valley., In the vicinity
of Aberdeen, S. Dak., it was estimated that 60 per cent of the
larvae had Lmerged from the livestock,

Soith F. C. Bishopp: At Abe-deon, S. Dak-, W. E. Dove reports the season
Dakota fairly well advanced and some Eypoderma larvae already mature and
out of the hosts on April 7.

Texas F. C, Bishopp: Cattle grubs were rather more abundant in the
vicinity of Dallas during the past winter than usual. However,
w:rble flies were app.-rently no more abundant than normal. Cattle
became free of all grubs about the middle of M-rch, At San Angelo,
howed-r, 0. G. Babcock found a few specimens which would not be
mature for about two weeks when he examined herds on March 20.

BLOT L IES

Texas F, C. Bishopp (April 20): Phormia regina Meig. have been very
abundant during the past month. They are now sufficiently numerous
to necessitate trapping and other control measures at the packing
houses. (May 24): The bljck blowfly is still present in considerable
numbers, the development of the species favored by the coSl spring.
At the packing houses in the vicinity of Dallas they still outnumber
C. macellaria.

D. C. Parman (May 21): Cynomyia and Calliphora disappeared. The
latter part of March the change in species during the last month
for a crapping period of 4S hours is as follows:

Species April 22 MayV 21

HORSE-FLIES (

Texas Do C. Pr"ian (May 23): The canyon horse-fly, Tabanus rubescens
Bellardi, has increased some during the month but is not yet very
annoying to cattle and horses except in local areas -,'here two

is that the flies are as numerous as far south as Carizzo Springs
as they are in the mountainsand the mountain infestation is

CHIK0T MIiTE (Der manyssus gallinae Redi)

Texas F. C0 Bishopp (April 26): Chicken mites are causing the usual
aixnt of loss where they are not "vigorously fought. (May 24):
The usual amount of loss and annoyance due to this parasite is
bein- exr.rienccd in northern Tex-s, but control is being
accomolished more effectively through the general use of
carbolineum and crude petroleum.

CCCIKr]T TICK (rgas miniatus Koch)

Texas F. C. ishopp (April): A good many reports are being received
of injury and losses among fowls due to the chicken tick. Much
