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
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

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.

CEREAL AND FORAGE-CROP INSECTS
C. P.R .L r--DrF s
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.
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)
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.

VXIITE GPRUJE (PhJLcehaa spp.)
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
Pest Survey Bulletin, Lachncstcrna arcua.ta Smith should be Lachncs-
t :rrn- vehmrens Horn.
T. J. Head lee (Ma- 1): I ar sending sorne wir(woTrs (Iel ,notus sp.)

hands of nrarket gardeners ai.d Lre more or less constantly under
,1 h Sw a.nk ( Ap i l 2C a 15) :
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.
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
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
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.
- 62 -
- 63 -
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-
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.
"VHFAT STRAYPOR (Fan-olita grandis Riley)
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.
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

J. F. Adams (May 20): Aphids were observed at Seaiord Arril 30.
At the present tire, 3 weeks later, they have apparently increased

an important factor.
Geo. F. Knowlton (May 27): Indications are that this will be a
serious pest in Cache County this year. Last year they destroyed
most of the sweet peas that were being raised for seed purposes.
STRIPFD CUCUPBER ?FETLE (Diaorotica vittata Fab.)
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-

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

IC C. Bishopp: These beetle larvae were found to be destroying
plants and gardens to a considerable exte-nt. Young beets, radishes,
kohlrabi, and tomatoes were being cut off by them.
F. C. Bishopp (April 25): These crustaceans are extremely abundant
in flower and vegetable gardens, especially in low ground. They.

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
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.
SYO-'--'"ITF LINDEN :"OTH (Ennomos sbbsi-n:rits HAn.)
H. F. Dietz (:ay 23): The eggs of the snow-'rhite linden moth

many of them have not been aole to move out to the leaves. Just
what effect this will have on the expected outbre---: of this insect

APPLE LE!FHOPP (fEmrnoasca rali LeB.)
A. I. Bourne (::ay 23): Our attention was called to the apple leaf-
hopper in the orchards just south of Arherst, where last year the
infestation was very heavy. A visit to these orchards on the 22d
indicated that there -.vas a probability of a very severe infestation
this season. ':7'ere nicotine had not as yet been used in any of the
sprays, it was very coraon to find 10 or a dozen nymphs of the hoppers
to a leaf; in some cases as many as 30 or 40. These sirall leaves,
scarcely an inch in w;idth, were already be-innirg to show the silvered
stippling which results from t".e feeding of these insects.
A. B. Buchhoiz (May 10):

SA' JOSF SCALE (Aspidiotus perr.ic-.ci.:s Comnst.)
A. I. Bourne ("ay 23): !lthou,?h reoorts vary from individual or-
chards, yet careful observers are beginnir? to be convinced that the
scale is gradually g-'iinri.i in abundance.
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
State and from the fruit oelt of the western part of the State indic-
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,
H. A. Gcsbard (iay 20): The San Jose scale was received on March 21
from Forest on a-ple; (March 19): From Haydenville on -each.

R. H. Pettit (iMay I4): I visited the Scudder orchards at Augusta,
Kici., on Sunday and examined 140 Spy trees which had recently been
sprayed for the apple flea-weevil. "r. Shutts, the man in direct
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
were hardly touched, excsernt as the beetles were driven out of the
Spies oy the spray.

all of our pear blocks here at the college were being quite heavily
infeoted with e-.:-s of this species. It was possible, in !..irny cases,
to count as many as 50 or 60 eggs to a short fruit spur. The hatch-
ing of the nyiaphs began the lOtn of the month. This was soTe'.',}a
later in the eastern part of the State, and an approximate figure
would be aroul.d the 12th to 15th. The insect was rather more abund-

some peach trees in all parts of the peach belt this year, and now
orchard bark- beetles are to be found in many of these trees.
PLUM CURCULIO (Conotrachelus r-.?nirhar Hbst.)
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
this section. Trees laden with fruit this season severely darazed
by punctures of this pest.
CV!'BIU, CLRCULIO (ConotrichelJs aar-'r4-icjs Say)
Georgia Oliver I. Snapp (May 10): This species of curculio is apparently
more common in Georgia peach orchards this year than usual. Some
mornings while jarring for C. neniunhar 10 per cent of the Conotrachel
captured were ana,.'-:pticus.

Don C. "'ote (April 9): One or more scars or serial cavities che-Ted
out of the side of the srall green cherry. This injury is noticed
as soon as the shucks fall.
A CASF-BF.RFR (Coleorhora sacr-rnrit.a Heinr.)
Theodore D, Uroahns (April 24): This small case-bearer, after hav-
ing been present in srall numbers for several years, has suddenly
developed in destructive numbers and is causing severe defoliation
and loss of crop amounting to at least 50 per cent of the fruit in
infested orchards of one locality.
CLERF.Y ;PHID (Mv-zus cerasi Fab.)
A. B. Euchholz (April 26): In Colunoia County these insects are on
the sweet-cherry buds in sral n.oers.
h. A. Gossard (lMay 20): The lack cherry aphid has been noticed
rather numerously on sweet cherry at 'fcoster, perhaps a rajori+y of
the leaves on son-e trees beitn curled.

Don C. Mote (April 29): One prune grower in Salem district reports
300 trees out of I400 infested., In apnle grower reports all his
2-year-old apple tre.s infcsted. The trees he says are dying.
Beetles apnoarently aoout ready to eirerge from burrows. A few had

as injuring raspberry at Evansville.
GR;PE 11E;LYBUG (Pseudococcus maritimus Ehrh.)
R. H. Pettit (May 14): The grape mealybug is very plentiful in the
grape belt of :"ichigan. Strong lime-sulphur killed practically all
that were hit but nothing else as yet has seemed to be effective.
Unfortunately the season is advancing so that strong lime-sulphur
can no longer be used.
CRAPE LEAF'HOPPER (Erythroneura comes Say)
K. E. Paine (April 26): Does not seem to be so very numerous in
soae vineyards where this pest was very serious last year. Prac-
tically none can be found in Chautauqua County.

CURIAFT APHID (:.vzus ribis L.)
A. I. Bourne (Hay 5): In one small planting here in tow'n the lice
were just beinrning tc cause the reddish discoloration of the leaves
previous to the forming of the distorted "pockets." Indications in
this articularr case were of a rather heavy infestation.
E. W. ienidenhall (ITay 16): Currant aphids are b-d on currant bushes
in sections in southwestern Ohio. Undersnray with nicotine solution
seems to be effective.
IMPORTD L.RRANT T'., (PFteronidea rijbesi S nop.)
C. 0. Hot;,h*-on (May 2): Adults are just begi ..-. 1 to appear around
the currant bushes. They are considerably later than usual and in

originated from Lancaster County on Way 15.
PECAN SPITTLE-FPU (Clastontera obtuse Say)
J. B. Gill (Ilay 23): The infestation of the pecan spittle-bug on
pecan and hickory trees is the worst that has been observed in years.
FALL "','O- (Hynhantria cunea Drury)
J. B. Gill (1:ay 23): 3any webs of the fall webworm are already
showing up on pecan trees, as well as on many kinds of forest and
shade trees. It is expected that the second-ger.erdt.lon iar-rae will
appear in such numbers as to cause serious defoliation in pecan or-
chards and nurseries.

F. L. Thcuas (ray 21): A rather unusual number of samples of
tne pecar phylloxera have been received from 15 counties scattered
over the eastern part of Texas and from the Coast to the Red River.
e have niot had opportunity to investigate any of these occurrences,
out 4K.q are certainly causing alarm to the various growers.
PEC.AN BUD-COTH (Proteontervx bolliana Slinr.)
J. Gill (:ay 23): The pecan bud-moth is quite prevalent this
year and is reported as occurring in injurious numbers on pecan
PECAN IlT CIFSE-BEFRE (Acrobasis hebescella Hulst)
J. B. Gill (fday 23): The pecan nut case-bearer is showing up in
various sections of the pecan belt. The roths have been errerging
for the past ten days and at this w-riting egg deposition on the
nut clusters is taing place in coirmercial pecan orchards of this
ie ec'iate region. It is too ec.rly to determine the extent of the
irJ estationi, but douotless there will be ccnsiderao-1e dv-x-ae to

E. E. School (T'ay 17): P trip to the southeastern and northeastern
parts of nre Sta-e revealed the fact that in the Counties of Carter,
Johnston, Varsha'l, and Bryan the pecan case-bearer is doing a c-reat
deal of damage. The n-oths are just now emerging arid the prospoects
are that we will hLve a very heavy crop of worrs infesting the nuts
within the next week or ten days. A number of sorayng demronstra-

Georgia Oliver I. Snapp (May 10): This cossid is nuc' er -rging from srall
pecan trees which have been heavily infested at Fort Valley.
Florida P. ,. Mason (May 27): An .r1'-], not yet definitely determined,
is doing s-ricus injury to citrus trees in Flo-ida. The center
of infestation appears to be at or near Tompa and the aphid has
spread north to Orange County and south at least as far as Fort
.jers. It seers to have been present around T&repa for about one
year. Th.e Lost severely infested varieties of fruit are ter-n-ies,
kings, and tangerines. Oran;es are fairly he -.tvily attacked, while e
grapefruits, on the whole, are only slightly so. One grove of
grapefruits, however, v:as observed to be heavy i rfsted. 01-in

COTTON FLEA (Psallus seriatus Rout. )
F, L, Thomas (May 21): Eomplaints regarding the cotton fleal
one of which proved to be a coccinellid, are beginning to be
CC"PxE, CTRCULIO (Chalcodermus aeneus Boh.)
J. A- Berly (May 12): This is the first injury we have had of
this insect for this season. They appear practically every spring
and do slight damage to young cotton quite often confused with
the boll weevil.
CORT ROOT APHID (Araphis maidi-rad.cis Forbes)
Jo A. Berly (May 12): We have had only bne report this season
in regard to the cotton root louse.
BOLL WEEVIL (Anthonomus grandis Boh. )
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.
B. R. Coad (May 1): The boll weevil was reported on April 23 as
plentiful on young cotton in the Rio Grande Valley in the vicinity
of Pharr, Tex.
F. Lo Thomas (May 21): The hibernation work with the boll weevil
is still being carried on, but to date only 10 weevils have
emerged out of over 5,000 which were placed in the cages.
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
TOBACCO THRIPS ('rankliniella fusca Hinds)
Florida F. S, Chamberlin (May 7): Heavy rains this month have practically
eliminated the infestrition of the tobacco thrips at Quincy.
SOUTHEUT GC-E: STINK-BUJG (iTczra viridula L.)
Florida F. S. Chamberlin (May 17): Very few stink-bugs have been observed
on tobacco planted around Quincy this season. It appears that the
low temperatures last winter reduced the numbers of this insect
to a marked degree.
TOBACCO BUD',70RE (Heliothis virescens Fab.)
Georgia F. S. Chamberlin (May 1): Tobacco fields in this region are
heavily infested with this p-st at Tifton.
GR12-T JUVIE BEETLE (Cotinis nitida L.)
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.
TOD CCO SPLITWORM (Phthorimaea ooerculella Zell.)
F. S. Oh nmb*rlin (May 8): Slight damage is being caused by
this insect in fields of brigItleaf tobacco.
TOBACCO HORIVOR.H (Protoparce sexta Joh.)
F. S. Charaberlin (lio.y 6): The tobacco hornworm is making
its first ppeirance in tobacco fields this season.

slug, has been found doing slight damage to newly set tobacco
PERIODIC CICADA (TiiciELI a se]Ut F endcim R.)
PERIODICAL CICAD (Tibicina septendecim L.)
To. P. Flint: Nymphs of the periodical cicada were found about
5 or 6 inches below the surface of the soil in southern Illinois
on May 15.
R. VW. Harned (:'Ay 27): Brood XXIII of the periodical cicada
is now appearing in large numbers throughout a large part of
the State. So far, specimens have been received from Carroll,
Calho-un, Benton, Bolivar, Copiah, BeSoto, Hblmes, Lafayette,
Leflore, Madison, :'arshall, Rankin, Sunflo-er, Yalobusha, and
GIPSY MCTH (Porthetria diar L.)
A. I. Bourne (May 23): The gipsy moth beg.'n hatching about
the middle of the nonth. On the rwhole they are finding them
rather fever than last year, in western Middlecsex County Mr.
Farrar reports finding only 20 egg masses in 1,200 young apple
BR0 In1-TAIL MOTH. (EuLroctis chrysorrhoea L.)
A. I. Bourne (May 23): In Essex County Mr. Stevens, who has
been connected with the clean-up Jork, reports the pest very
generally spread throughout that section, but very few in number
both in orchLrds and along the hi4'-"mys.
In Niddlesex County the pest in orchards seems to be practically
extinct, Mr. Farr reporting from the town of Lincoln finding
only six or seven in a block of nearly 2,000 treas.
In the northern part of TWorcester County the pest is practically
wiped out, except for wild growth and along the highrays. In the
southern part of the county one grower reports finding approxi-
mately only one nest to 1,000 trees in his orchards, and from
his observation believes this is typical of that gencri-l
locality. In fect, mcn:y !-o7re:es in that section have come to
regard! that as havin. reL.cied a negligible st .e as far as
being a pest which demands their attention. This la borne-out
by Mr. Davenport, the President of the State Fruit Growers'
Association, who reports that in his orchard in the town of
Grafton he has failed to find any brown-tail caterpillar nests
thus far this season.
TM.RPIN SCALE ( ecanium nirofasciatum Perg.)
L. Haseman (May 22): The terrapin scale is attracting much
attention in Carthage and other southwestern Missouri cities,
on shade trees largely.
BAGWORM (Thridopteryx e-phemeraeformis Haw.)
H. A. Gossard (May 20): On April 11, bagworm coccons were
received from New Vienna on plum,
L. Baseman (May 22): Bagvorms are just beginning to emerge in
central Missouri and are practically threatening to foliage and
fruit in some sections of southwestern Missouri. Reconmnendations
on the use of arsenical sprays will undoubtedly help materially
with this season s epidemic.
BOXELDER. APHID (Periphyllus negundinis Thos.)
M. Ho Swenk (April 20-May 15): An outbreak of the boxelder
aphid is repor-ted from Greeley. County.
EUROPEAT ELM SCALE (Gossyparia spuria Modeer)
E.L. Chambers (May 15): Several elms killed by this insect. Many
weeping and American elm trees practically plastered with the

ELM COCKSCOMB GALL (Colopha ulmicola Fitch)
L. Haseman (May 22): More abundant on young wild elms than I
have ever seen them before.
ELM SA7FLY (Cimbex americana Leach)
A. I. Bourne (May 23): The elm sawfly tas first observed on
May 18 and 19, when the' adult flies were found ovipositing on
the small leaves of Camperdown elm here on the campuSd. This
date is approximately the same as that on which the first speci-
mens were noted a year ago.

spotted fever have occurred in northern Colorado this spring.
Both of these ,iero in regions where the disease has rarely
or never occurred before.
CHIGGERS (Trombicula tlalzahuatl Murray)
F. C. Bishopp (May 24): Chiggers were first observed in the
vicinity of Dallas on May 5, and became very annoying to man
by the middle of the month,
". 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.
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

Texas F, C. Bishopp (April 20): Phormia regina Meig. have been very
abundant during the past month. They are now sufficiently numerous
