OUTSTANDING ENTOMDLOGICAL FEATURES IN THE UNTITED STATES FOR APRIL,1923.
In reviewing the general entomolhgical data accuculated by
the Survey during 1921 and 1922 and cowparing these -ith the data so far
received this year, it appears that the entoz.ologiesl season is about two
weeks later than normal.
From present reports the indications are that.the HEssian fly
will not be a serious faftor in this year's wheat crop over nost of the
important wheat-growing regions.
The chinch bug is still a threatening factor in the Ohio River
region and in the Upper Misssissip- Valley, the bugs having passed the
winter successfully as far north as southeastern South Dakota.
The Great Plains false wireworm is again proving a serious pest
in western Nebraska.
A telegraphic report has been received of a lar~e brood of Morron
orickets now hatching in north-central Wyor-ing.
The codling moth wintered well in New York and Washington,
deppite the cold winter, which killed over 25 per cent of the larvae which
were above the snow-line in the latter State.
Eggs of the several apple aphids were hatching as early as TMarch
30 in the Ozark region of Arkansas; April 7 in southern Idaho; April 9 in
Indiana; and April 20 in -vestern ~ew York-
Infestation of the fruit-tree leaf-roller is rapidly increasing
in Idaho* This year the egg count indicates an increase of 300 per dent
over last year's infestation.
The San Jose scale continues to be a serious fictor in apple
orcharding in New York, New England, and the Ohio River States. In Indiana
the region of serious infestation is extending into the northern part of
the State. This insect is also a very serious pest in northwestern
The pea aphid is seriously infesting the entire cannery pea
section in Stanislaus County of California and a lighter infestation ex-
tends over the Santa Clara Valley. This insect is also doing considerable
damage to alfalfa in the vicinity of Topeka,Kans. The Kansas infestation
is over a rZi~on" where the Trowin: of garirn peas is rather extensive.
Here the association of alfalfa and peas is sug~ sted :s beinz favorable
for the multiplication of this insect. Aphid infest.ations w.ere so
serious in the Santa Clara Valley on spinach that seven canneries ceased
canning this product this sprin-g The damage was not so ruch the
infestation of the aphids as the presence of such enormous numibers of
syrphid larvae that it was not possible to remove ther. fron the spinach
in the washing process.
Brucels --easuring worm is reported for the first time as being
present in the Okanogan Valley of Tashin-;ton State.
OUTSTANDING ENTOMOLOGICAL FEATURES IN CANAIDA FOR APRIL, 1923.
The spring in Canada is backward in r:ost parts of the Dominion,
with the exception of British Columbia, where the season is from two to
three weeks in advance of last year. In parts of the Prairie Provinces
it is expected that the farmers will be able to do very little work in the
fields until about the first of May. In Quebec and the Maritime Provinces
the spring is about two weeks later then lzt year. Unusually cold ~9ather
with much snow was experienced in Ontario uring the first two weeks of
April, but towards the end of the month a warz, spell occurred and spring
ploughing will be general by the first of May.
The pea weevil has shown an increase in numbers in certain sections
of Ontario, during the past two years. In British Columbia this insect
is reported from several sections whihh were previously fninfested. The
latest report is from Lillooet, B. C., where there is a serious infestation
of this insect*
The striped cucumber beetle is beconing more prevalent in the
Prairie Provinces. In Manitoba in 1922 it was comron throughout the
southern sections from Melite to Winnipeg.
The roadside grasshopper, Carnula pellucida Scudder, outbreak which
occurred over an area of 3000 square miles of cattle range in the neighbor-
hood of the Nicola Valley, B. C*, in 1922, and wh.ich ;ws probably the worst
outbreak in the history of the province, is expectoedto re-occur this year
over the sarue area but in a very mild foru. It is feared, ho-."over, that
some of the largest dry.farming sections will suffer severely.
The sugar-beet root aphid, Pemrhirus betae Doane, is juided by
conditions as becoming increasingly prevalent on mangels in the Lower
Fraser Valley, British Columbia.
The western wheat-stem sawfly, Ce-hus circtus JTort* is overwinterivn
in large numbers in the Prairie Provinces. Indications point to severe
damage during the coming year.
The Colorado potato beetle has experienced favorable winter
donditions in the Prairie Provinces and everywhere is expected to emerge
from its winter quarters the last two weeks of May.
Tha nose bot-fly, Gastrophilus veterinus lark, is yearly assuming
more importanrsin the Prairie Provinces and its distribution appears to
The Hessian fly will cause loss in Manitoba it is feared* The area
of infestation will doubtless occur in the territory north of the
Canadian Pacific Railway line in areas of the greatest rainfall.
TIa eastern spruce bark-bpetle, DeXd roctaokis piceaserda Kirby, has
been active in two localities in Canada during the past few years. An
outbreak of increased proportions is anticipated this year in the Gaspe
Peninsula, in Quebec Province, due to the last year's brood concentrating
on the weakened trees of a large burn. The Porcupine mountain outbreak
in Saskatchewan almost completely died out last year and is not expected
to cause any trouble this year.
The European cornoborer wintered successfully in Ontario, the
very low mortality of 3 per cent bein- recorded in overwintering experiments.
CEREAL AND FORAGE.CROP INSECTS
HESSIAN FLY (PhytorphaQa destructor Say)
Illinois W, P. Flint (April 30): Adults of the Hessian fly have
not yet been found in the fields.
Indiana J. J. Davis (April 20): The Hessian fly is not abundant.
Sowing at the right time has doubtless been effective in
keeping down the Hessian fly in the northern half of Indiana.
A late wave last fall is responsible for some fly infestation
in southern Indiana. In Adams County in the northeastern
part of the State we examined last fall (November 22) several
fields sowed on different dates, scattered over the county*
The results of these counts were ..s follows:
Date sowed Result of count
Aug.29 Infestation too heavy for
d finite count
Sept.10 68.5 per cent of plants infested
12 33.8 per cent of plants infested
15 38.7 per cent of plants infested
23 26.6 per cent of plants infested
25 11.5 per cent of plants infested
27 1 :3r cent of plants infested
Oct-1-10 :. -.r cent of plants infested
The fly-free date in the section of the county visited in September
26. The plants were not heavily infested, as the fly was corparatjve
ly scarce last fall.
In some counties of the State occasional early-sown wheat fields
are to be found and these are invariably more or less heavily infested
with the Hessian fly. Our five sowing plats gave the following
fly infestation last fall.

Missouri A. F. S tter .hwarnit (April 10): No deposition of 3 3zs. Pupation
is just beginning within the fla1seed in St. Louis County.
The abundance is greatly reduced from the fall of 1921.
R. C. Lange (April 11): Volunteer :.heat in Franklin County
is 100 per cent infest di,and crop 'ihe...t is ne:rly as badly
infested. This locality shons the heaviest infestation found
in the St- Louis County neighborhood. Pupation is just
CHIIUCH BUG (Blissus lauco-terus Say)
Indiana J J. Davis (April 20): 7e anticipate heavy infestations in
a larger section of the State than last year. The center of
infestation has -.oved northward. All counties in the northern
half of the State arc "ore or less infested. Bugs w:vre active
out not flying a fea woeeks ago. To da te none have been
observed flying fror -winter quarters.
South Dakota H. C. Severin (April 7): Infestations exist in Bon Homre,
Doglas, and Charles -ix Counties. The bugs ca~e thrcu-h
the winter in -ood condition.
YELLOW.SUGAR-CA, APHID (Sihha 1_i va Forbes)
Texas E. E. Russell (April 11): At Gainesville conditions are very
different w;ith re-ard to Sirha flava, for this pest occurs
in from 50 to 75 per cent of the fields in this section-
Often the colonies are very srnally then again they get to be
of good size, some of the affectin~ from 15 to 25 acres.
While the grain is not so co:plately killed, as in the case of
Toxoptera rork, the stand is ruined in rany cases and the
rer:aining plant. are spindling and sickly looking. In two
fields of fall-sow~n "iheat, about 100 acres, -which were
exa':ined on Friday of last -week, large colonies averaging
#ro= 15 to 20 feet in diameter occurred every few y arLs over
the entire area. It would be safe to say that t t least 50
per cent of the crop had alreJdy been injured, but the 7ost
discouraging thing in this connection is the fact that the
parasites, except ladybugs, do not appear to be raking =uch
headway. I have never found -ore than 5 per cent to have been
attacked by the true parasites, aid in my ex-:inrtion of
the two fields just --entioned I was not able to find a single
GRE.EUG (Toxcatera zraminur. Rond.)
Kansas G. A. Dean (April 17): Reporters who have been in south-
central Kansas, looking into the grsenbug situation, report
that they have the far.ers fairly well organized for rloaing
under the infested spots. In fact, many of the spots -vr3
plowed under before they left that nart of the State. The
weather reports are for wat-er, and if the weathar conditions
are favorable for good plant growth, and also for the increase
of the predacious and parasitic enemies, I believe the greenbug
has done all the injury it will do.
S* J EHunter (April 20): On April 10 we received from Crystal
Springs, in Harper County, a package of wheat infested with
greenbugs. Mr- Beamer of this Departarnt returned yesterday
from that region and reports one 40 acre field infested with
greenbugs, with a few dead spots appearing in the field. He
found no hymenopterous parasites, but an abun!ance of ladybirds.
He reports from 8 te 10 coccinellid larvae in 3 inches of drill
row. In his judgment these predacious insects will prove more
effective than dny reredial measures we could institute. After an
extended survey through Harper County he found only one other
field of wheat in which they -'ere present in appreciable numbers.
The wheat is in an excellent condition, and, in his judgment,
there will be no -aterial loss.
E. E. Russell and C. H. Gable (April 20): In Wichita, Archer,
Texas Young, and Parker Courtisa a number of colonies of Toxoptera
were developed. These spr3ad to some extent and. threatened
some injury. At this time, hoeev~r, parasites have practically
exterminated the older colonies, and. the new. infestations are
being so effectively controllae that little damage is anticipated,
and. the farmers,in general, feel that there is promised a better
grain crop than for a nunber of years. The situation in Collins,
Grayson, Denton, and Cooke Counties is -ach the same, except
that the control by parasites has been much more complete, so that
in many fields previously infested it is difficult to find any
of the aphids.
Oklahoma Ernest E. Scholl (April 25): We have just assisted in conducting
a very successful dusting experiment on greenbugs in the heavily
infested greenbug field seven miles west of Still-vater in which
nicotine dust was used. The results so far show 90 per cent
mortality wth no bad effects on lady beetles.
New Mexico W. E. Emery (April 3): This aphid. is attacking certain varieties
of fall wheat in Dona Ana County, doing considerable damage,
spots being nearly entirely killsd. About 60 per cent of the
crop is damaged.
R. Middlebrook (April 11): Since writing you last, I note a
heavier percentage of damage by the greenbug to the wheat, the
increase being about 10 per cent, making the total damage 20 per
cent in the several fields of wheat which I have under observation.
WHEAT STRAW "OP (Harmolita grandis Riley)
-Missouri Hi E. Roberts (April 6): In Jefferson County adults appeated
moreabundant about the straw pile than over the field, though
generally distributed. Wheat followed wheat; the stubble was not
well plovred unO-r. Infestation is r-oderate, cozr--red with
the average year. Atalts ar- at large with no parasites. The
weather ts sunny and hot. (April 11): Three fields were examined
at Pacific, Franklin County. Infestation is severe. Adults
are at large, inta form. The -~eather ia sunny and warn.
Xdaho Claude 7akeland (April 16): Adults are emerging fror old
stubble of springtplanted wheat of 1922. The crop is daaged
55 per cent, by counting stems.
Texas M. C. Tanquary (April 23): Mr. R. R. RBppert reports injury
by wireworr to wheat and sorghuzs in west Texas.
GR2AT PLAINS FALJS2 wIRO70RM (Eleodes opaca Say)
Nebraska M. H. Swenk (April 18): The Great Plains false wirewonr has
again this spring shown considerable capacity for doing injury
in the wheat fields. Daring the first week in April it was
reported working in ths wheat fields of Hitchcock Countrty, some
fields being very badly infested, and also in Perkins County,
where in wheat fields that followed suier-fallowed land the
false wireworms cozpletely istroyed -: plants, in the vizinity
of Grant The next week si.ilar reports vwre rec:ivd from
Cheyenne County, where this pest spoiled many stands of -heat
this spring. During the last week in MIarch further reports
of injury in the fields of Nance County, where trouble was
experienced last November, were received.
CUTWWORMS (species unknown)
Texas 0. G0 Babcock (April 17): Almost every bunch .of grain, horehound,
and many other weeds, as well as 7rass plots, at Sonora shows the
presence of cutwo-rs. OKin': to h"avy and cool r..ins, dage
does not show as yet- No study has been =~de as to the parasitisn
of the -:wor.ns
MO1ON CRICKET (Anabrus sir.lex Hald.)
Wyoming Stewart Locl~rood (Telegram. dated April 39): Reports that the
Mormon cricket is hatchin7 in serious numbers at Ther-opolis,
Wyoming, over an area of approximately 2,000 acres. The
:crickets are just hatching at this tirne
Idaho D. B*. Thelan (April 16): Eggs are beginning to hatch in
TEELEEISBOTTED CUCUMBER-BEETLE (Diabrotica 132-uncttat Oliv.)
Louisiana To H. Jones (April 2): At Baton Rouag a few oung corn plants
have been noted that showed, injury ue to larvae. Larvae are very
coTton at the roots of scattered volunteer oat plants in the
same field. T.hes l1rvae are of various sizes, somo full-gro,7n
and preparing to pupate. As maany as 55 larvae vere found at the
roots of one stool of oats.

CLOVER ROOT-BORER (Eylastinus obscurus Marsh.)
Idaho D* B. Thelan (March 30): In 1922 the first crop of clover
hay; from a field was 22 tons. At the second cutting there
was not enough to cut. I visited the field, March 30 and.
found very few plants growing. Some of these were injured.
but evidently had overcome the injury. Countless nuTmbers of
beetles were found in clovdr roots that lied last fall. The
locality of the infestation -;as Meridian, Ada Gounty. The
crop was damaged to the extent of 90 per cent%
GIANiT SKIPPER (species unknown)

A BYRRHID (Arthicvrta sp.)
California E. 0. Essig (March 9): Last year adults of Amphicyrta were
taken in the act of destroying a considerable amount of
pasture vegetation, includinn grasses and weeds.
CODLING MOTH (Carpocaosa romonella L.)
New York P. D. Rupert (April 14): The larvae appear to have wintered well
and can be found very readily in Dutchess County.
P. J. Chapman (April 14): Larvae are numerous in Genesee County.
Washington E. J. Newcomer (March 27): In the eastern part of this State
December temperatures of 150 to 180 below zero killed from 25 per
cent to 35 per cent of the wintering worms above the snow line.
In spite of this there are at present many more live worms in
orchards than usual, on account of the heavy infestation lant year.
GREEN APPLE APHID (Aphis pomi BeG.)
New York P. D. Rupert (April 16): In Dutchess County eggs are moderately
abundant and general. (April 14): Present in large numbers over
practically all of Dutchess County.
G. E. Smith (April 6): Found abundant in two orchards in Orleans
E. W. Pierce (April 14):: The eggs seem to be rather abundant in
P. J. Parrott (April 20)! Hatching of the grain aphid has been

Indiana J. J..Davis (April 20): The majority of aphids on apple examined
are the apple-grain species. A few, 2 to 10 per cent, are Anhis
sorbi, and exceptional individuals Aphis pomi.
Idaho Claude Wakeland (April 10): Newly hatched young are collecting
on terminal buds of apple trees at Parma, buds are bursting, and
an occasional leaf is beginning to unfold.
APPLE-GRAIN APHID (Rhopalosiphum prunifoliag Fitch)
New York G. E. Smith (April 6): This species was found abundant in two
orchards in Orleans County.
T. C. Murray (April 1i): Eggs are just beginning to hatch in

sorbi, and exceptional individuals jAhiLs Ioi,-
Arkansas A. J. Ackerman (April 5): Newly-hatched aphids first were observed
on March 30 at Bentonville. Only an occasional apple bud is open
at this date.

P. D. Rupert (April 14): Present in large numbers over practically
all of Dutchess County.
G. E. Smith (April 6): Found abundant in two orchards in Orleans

'OOLLY APPLE APHID (Eriosoma lani;eru: Hausr.)
New York R. F. Illig (April 16): A report has been received from Ontario.
P. D. Rupert (April 16): Danage to sone young orchards is very
noticeable in Dutchess County.
Massachusetts A. I. Bourne (April 20): From Essex County, in the northeastern
section of the State, a report which was made on the 11th of April
stated that very few of the early stem rothers of plant-lice have
been noted as having appeared on the buds. (April 23)" In a
letter from Pittsfield, in Berkshire County, it is reported that
there ,appear to be fewer plant-lice eggs than norrally are found.
The weather has been so cold, however, up to the present tire that
no definite information can be secured. It is still too early for
plant-lice to hatch in northeastern Essex County, as there are still
no signsof buds breaking and leaves coming out.
Indiana B. A. Porter (April 4): The first newly-hatched aphids have been
observed at Washington.
,Washington E. J. Newcomer (March 27): Judging from the very small number of
winter eggs which can be found, apple aphids will not be serious
FRUIT-TREE LEAF-ROLLER (Archips argyrospila "'alk.)
New York P. D. Rupert (April 16): A few egg masses have been observed on
apple in Dutchess County.
E. W. Pierce (April 17): Eggs have been noticed in orchards in
every section of Ontario County,
P. J. Chapman (April 14): Eggs have been observed in several
orchards in Genesee County.
Idaho Claude Wakeland (March 16): We have recently been making some
egg counts on this insect, preparatory to experimental spraying,
and find that in the orchard in question the average increase of
infestation for the year is a little more than 300 per cent. On
one tree only there was a decrease in the number of egg masses, and
the extremes varied to as great an increase as 1,400 per cent. Our
method of determining the rate of infestation and increase is to
count all egg masses on a given branch or portion of a tree and to
remove all eggs that have hatched on previous years. (Mtarch 30):
Count of the egg masses on 11 trees at Lewiston showed an average
of 28 old egg masses and 64 new egg masses per tree. The infesta-
tion this. year is approximately 238 per cent of that of any previous
BRUCE'S ?MEASURING WOPM (Rachela bruceata Hulst)
Washington A. L. Melander (April 20): We have just received specimens from
Tonasket in the Okanogan Valley of what was thought to be the bud
moth. It proved, however, to be Bruce's measuring worm. This
material was sent in by Thomas Thorson, who previously had sent
specimens of last year's apples bearing stings very similar to
those caused by codling moth larvae. His staterrent about the
stings was that the stings were prevalent in unsprayed as well as
in sprayed orchards, and were attributed to the summer generation
of the bud moth. The measuring worm was now sent in as the spring
generation of the bud moth, We have not been able to diagnose
what is responsible for the stings on the mature apples, although
the codling moth and the lesser apple worm are both present in his
region. This is the first record we have in Washington of the
occurrence of Bruce's measuring worm.
TENT CATERPILLAR (Malacosora americana Fab.)
New York P. J. Chapman (April 14): Eggs have been observed in several
orchards in Genesee County,
E. W. Pierce (April 17): Eggs have been noticed in neglected
orchards in Ontario County.
Massachusetts A. I. Bourne (April 23): The apple tent caterpillar appears to be
very scarce at Pittsfield, Berkshire County; few, if any, egg masses
are to be found except on wild cherries or on scattered, uncared-for
apple trees. A letter from northeastern Essex County reports
"millions" of apple tent caterpillar egg masses, greater numbers than
have been seen for years, and on April.19 one or two egg rasses were
found to be just beginning to hatch.
Gebrgia J. B. Gill (April 5): The first hatched egg-mass of the apple-
tree tent caterpillar was observed on March 10 at Thomasville.
In this section the nests are now commonly seen on wild plum and
wild cherry trees.
Arkansas W. J. Baerg (April 1): Reported from Fayetteville on wild cherry
as more abundant this yearl
RED-BhNDED LEAF-ROLLER (Eulia velutinana Walk.)
Pennsylvania S.W. Frost (April 23): The first adults of the red-banded leaf-
roller issued April 16. Egg laying cormenced on April 23. The
eggs are now abundant in the orchards.
BUDMOTH (Tmetocera ocellana D. & S.)
Indiana B. A. Porter (April 24): Larvae noted feeding in unfolding leaves,
SPRING CANKER TO (Paleacrita vernata Peck)

New York W. T. M. Forbes (March 25): Heavy flight observed; also seen on
various dates at Ithaca.
New Jersey T. J. Headlee and A. A. Lance (April 2): Numerous rales and females
have been observed in a wooded area at Bernardsville.
CLIBING CUT OR"S (Lampra spp.)
Washington E. J. Newcomer (April 14): In the Yakima Valley these cutworms
are much less numerous than last year, being of little consequence
at this tire.
APPLE M AGOT (Rhaaoletis pooonella Talsh)
New York C. R. Crosby (January 28): Infested Rose Sweet apples have been
received from Wayne County. (April 13): The entire crop in a
large orchard at Hartsdale was ruined last fall.
TREE CRICKET (Oecanthus sp.)
Pennsylvania S. W. Frost (April 23); The punctures of a species of tree cricket
were found abundantly in Franklin County. Many of the punctures
are accompanied by a fungus infestion, probably fire blight.
SAN JOSE SC/LE (Aspidiotus perniciosus Comst .)
New York C. R. Crosby (April 6): Trees are badly infested at Lyons.
(April 10) : A small orchard is badly infested at Riverhead.
(April 12),: An orchard is lightly infested at Hartsdale.
A. L. Pierstorff (April 14): Abundant in most orchards in
P. D. Rupert (April 14): Very prevalent in many places and can
be found in nearly every orchard in Dutchess County. (April 16):
Moderately abundant in most orchards.
F. H. Bond (April 14): Has been reported in several well sprayed
orchards in Oswego County.
P. J. Chapman (April 7): Does not appear to be very prevalent even
in neglected orchards in Genesee County.
R. F. Illig (April 16): Has been reported from Sodus and 7illiamson.
E.7. Pierce (rpril 17): A little has been found in most orchards
but it is not serious in well sprayed orchards in Ontario County.
Indiana J. J. Davis (April 20): This insect continues as the most serious
apple insect and is now extending its range of destructiveness to
northern Indiana. It has a comparatively lo winter mortality.
lany growers are using the new lubricating-oil emulsion. ScE: are
reporting trouble with this raterial. Appare :tly t'is is frequently
due to the use of lime-sulphur barrels to ccnt -in toe stock eulsion,
or to tanks having been previously used for lime-sulphur. In other
cases the emulsion was, apparently, imrroperly rade or the water used
to dilute the stock solution was of such a nature that it caused a
separation. In our spray tests the miscible oils and the emulsion
continue to give satisfactory controls, the dry and liquid line-
sulphurs being less satisfactory.
B. A. Porter (April 25): Winter rortality has ranged at Vincennes
from 25 per cent to 65 per cent dependin- mainly on condftion of wood.
Arkansas A. J. Ackerman (April 5): The San Jose scale has causerd ore dar-ae
to orchards of northwestern .rkansas in the last two years than any
other pest during the history of aprle -ro,.in7 in this section. A
material reduction in the scale infestation in Benion County was
effected with the dorarnt lubricating-oil emulsion spray applied
last spring. During the dormant season of 1922-23 about 95 per cent
of the orchards of Benton and 7ashin.ton Counties have been sprayed
with lubricating-oil emulsion for this scale.
Idaho Don B. Thelan and Claude Wakeland (April 14): Apple trees are worst
infested, but the scale is attacking many other kinds of fruit trees,
shade trees and shrubs in Ger and Canyon Counties. Infestations
this year are the worst that have occurred in years. Horticultural
inspectors say 1922 was the worst year they have ever experienced in
OYSTTR-SHELL SC'LE (Letidosanhes ulmi L.)
Eaine B. Alexander (April 7): Trees of 'ecIntosh red apple ai'e nearly
covered at Richmond.
New York C. R. Crosby (March 7): Infested twigs have been received from
Rochester. (April 2 : Trees are badly infested at Hinckley.
(April 9): At Cambridge apple trees are badly infested.
R. F. Illig (April 9 and 12): Reports have been received of
infestations at Sodus Point and Newark.
E. W. Pierce (April 14): The oyster-shell scale is prevalent in
most orchards in Ontario County. (April 17): Prevalent throughout
A. L. Pierstorff (April 14): Abundant in many orchards in Chautauqua
P. J. Chapman (April 14): Generally prevalent in Genesee County.
EUROPEAN RED 1'ITE (Paratetranvchus pilosus Can. & Fanz.)
New York C. R. Crosby (March 29): A specimen has been received from
P. D. Rupert (April 16): Eggs are very abundant in Dutchess County.
Pennsylvania S. W. Frost (April 23): Eggs of the red-spider are abundant in
Adams County this spring. The first eggs hatched on April 21,
Indiana B. A. Porter (April 25): Winter eggs fairly abundant in the
vicinity of Vincennes, on apple and peach.
Washington E. J. Newcomer (tarch 27): Winter eggs are much more numerous
than usual in the Yakima Valley.
TARNISHFD PLAPT-BUG (Lvgus cratensis L.)
New York P. J. Chapman (April 14): Adults have been found hibernating under
the bark of old apple tree in Genesee County.
Illinois J. H. Bigger ( 'arch 27): Adults have just been seen flying out of
hibernation near Jacksonville, Vorgan County.
SHOT-HOLE BORER (Scolytus ruEulosus Ratz.)
New York C. R. Crosby (April 4): Apple trees are badly infested at Dansville.
THREE-CORNERED TREEHOPPER (species undetermined)
Washington E. J. Newcorer (March 27): This undetermined species deposits
winter eggs in the twigs of the apple, often severely damaging young
trees. The hoppers, undoubtedly, feed on the cover crops and weeds.
PEAR THRIPS (Taeniothrips inconsequens Uzel)
New York A. B. Buchholz (April 16): The first thrips was noticed on the
buds at Hudson.
Oregon E. J. Newcomer (April 6): This insect was first noted in the r'alla
Valla Valley in 1922; some damage was done, but it is not yet serious.
On April 6, 1923, one or two adults were found on every open blossom,
and some egg punctures were noted in the young fruits at Freewater.
PEAR PSYLLA (Pslla pyricola Foerst.)
New York C. C. (April 4): Adults are out and rating is taking place
at -.ilton and Highland. (April 10)-: Oviposition was observed for
the first time at F'iddlehope and Marlboro.
P. D. Rupert (April 14): Adults are becoming active, and in sore
of the warmer orchards there is considerable oviposition. (April 16)
Adults are very abundant in Dutchess County.
G. E. Smith (April 2, 6, 7): Adults came out on April 2 and were
observed abundantly on the 6th and 7th in Orleans County.
R. F. Illig (April 5): First adults are out at Sodus.
E, W. Pierce (April 12): Adults were found active in Ontario County.
(April 17) : Quite abundant in the eastern part of Ontario County.
A. B. Buchholz (April 14): Egg laying has been abundant and active
in some cases in Columbia County.
TWELVE-SPOTTED CUCU VERP BEETLE (Diabrotica 12-punctata Oliv.)
Georgia 0. I. Snapp (farch 31): These beetles are feeding considerably on
peach blossoms, especially where the trees are near a garden. Damage
has also been noted to the young terminal leaves of year-old pear
and peach trees at Fort Valley,
PEACH BORER (Aegeria exitiosa Say)
Georgia 0. I. Snapp (April 21): Results from paradichlorobenzene have been
uniformily excellent in the Georgia peach belt this year. Great
quantities were used and, from reports, all growers are veill pleased
with the results, Some few w0o failed to make the application last
fall are trying spring treatments. These spring treatments 1were
given about April 1.
PLU CURCULIO (Conotrachelus nenunhar Hbst.)
Georgia 0. I. Snapp (April): The number of adult plum curculios that sur-
vived the winter of 1922-23 in central Georgia is arwarertly very
large. They are now appearing from hibernation in numbers. 51.7
per cent of the beetles confined in a hibernation cage, with Benruda
grass sod, on September 1S, 1921, appeared from hibernation during
March. The appearance of the beetles from hibernation in other
cages during March was as follows: Dried leaves 4645 per cert,
Spanish moss 34.2 per cent, pine needles 29 per cent, trash 21.2
per cent, and bare soil 5.2 per cent. The winter has been mild,
................. A e ', or a area a n, ...,
with the exception of two periods of short duration. During one
of these the minimum temperature recorded was 18F- and during the
other 230F. (April 15) : The appearance of beetles from hiberna-
tion cages, with various types of hibernating quarters, to April 15
inclusive was as follows: Bermuda grass 67 per cent, @a6 leaves 61.5
per cent, Spanish moss 48 per cent, pine needles 38 per cent, sticks
and trash 22.5 per cent, and bare ground (no hibernating quarters)
6.75 per cent. (April 21) : The first larva of the season was found
in peach on April 18, which is several weeks later than last year.
This is undoubtedly due to the very cool spring, which has held back
the development of the fruit and also retarded the appearance of the
adults from hibernation.
Jarring records show that the curculio is much less abundant to
date this year than last, and there is an enormous reduction as
compared with 1921. The results of the three years of the curculio
suppression campaign are now becoming very evident.
Louisiana T. H. Jones (April 4): The freeze of V.arch 20 killed all fruit and
bloom. Few eggs were noted today in fruit that has set since that
date, and 1 adult was observed. (April 14) : Fruit containing
small larvae is common on trees today, but only a few "drops" have
TWELVE-SPOTTED CUCUMBER BEETLE (Diabrotica 2-e uncata Oliv.)
Georgia 0. I. Snapp (March 31): These beetles are feeding considerably on
peach blossoms, especially where the trees are near a garden. Daemge
has also been noted to the young terminal leaves of year-old pear
and peach trees.
tin. F. Turner (April 12): Very abundant in some orchards in Jasper
and Morgan Counties, feeding on foliage; no real damage as yet. I
fear severe injury to corn later.
SAN JOSE SCALE (Asidiotus perniciosus Comst.)
Georgia 0. I. Snapp (April): Crawlers of the San Jose scale have been
collected from peach trees near Fort Valley each rnonth during the
past winter. This proves that in the latitude of central Georgia
some of the scale insects pass the winter in the full-grown stage.
PEACH AND PLUW SLUG (Eriocampoides amygdalina Rohwer)
Louisiana T. H. Jones (April 4): The larvae of this sawfly did considerable
damage to peach foliage at Baton Rouge last year. Adults have been
noted to be common in the field today, resting on peach foliage, and
what are apparently eggs are common on the undersides of leaves.
TEMITES (Reticuliterres flavipes Kol.)
Nebraska MI H. Swenk (April 18): The larger roots of several 3-year-old
cherry trees which died last surrer were being mined by termites in
Franklin County a rather unusual instance of insect injury that
caie to notice from March 10 to April 15.
PLUM CURCULIO (Conotrachelus nenuDhar Hbst.)
Georgia 2.B. Gill (April 5): On March 27, while inspecting sore plum
thickets near Thomasville, I observed that egg punctures of the
plum curculio were quite common on the small wild plums. On
April 2 I had occasion to examine a good batch of wild plurs, find-
ing many eggs of the curculio in the fruit. Yost of the er-gs had
not hatched at this time, but an occasional larva of considerable
size was observed, indicating that some eggs must have been hatched
for at least a week.
BRON PLUM APHID (Hysteroneura setariae Thos.)
Georgia 0. I. Snapp (April 10): The rusty brown plum aphid is very bad at
the present time on plum trees in several home orchards around Fort
CURRANT APHID (Wyzus ribis L.)
New York P. J. Parrott (April 19): Hatching of aphids has been observed
SAN JOSE SCALE (Ispidiotus perniciosus Corst.)
New York J. B. Palmer (April 4): Part of one planting was killed out at
East Bloomfield. (April 9): Bushes are badly infested at Ithaca.
C. C. Wagoner (April 6): The scale is present wherever observations
were made along the Hudson River. (April 13): The scale is worse
usually on Fay than on Perfection, and least on rilders. Infesta-
tions have been found in Ulster County along the Hudson River.
PECAN SHUCKTORB (Laspevresia caryvaa Fitch)
Georgia J. B. Gill (April 5): Larvae of the pecan shuck-Torr have already
been found attacking pecan buds and shcots.
PECAN BUD ROTH (Proteooteryx bolliana Sling.)
Georgia J. B. Gill (April 5): Larvae of the pecan bud roth have already
been found attacking pecan buds and shoots.
PECPN CASE-BEPRER (Acrobasis nebulella Riley)
Georgia J. B. Gill (April 5): Larvae of the pocan leaf ease-bearer have
been emerging from their hibcrnacula during the last 10 days and
are now attacking the unfolding buds of certain important varieties
of pecan, especially the Frotscher and Schley. Up to this date
the larvae have not begun to attack the buds on Stuart trees, which
variety is one of the latest to put forth its f lic e in the spring.
Lany pecan g rowers in this section sprayed their o:iV- s for -}is
insect during the late summer and early fall and they have succeeded
satisfactorily in controlling this pest. According to our observa-
tions, some sprayed orchards will show more or less durage because
of careless spraying.
The hibernating larvae of the pecan leaf case-boerer have been
found to oe highly parasitized by Secodella acrobasis Cwfd., which
is considered a very effective parasite against this pest. Great
numbers of adults of this species have been reared frorm Taterial
collected in this general locality. The adult parasites have also
been observed frequently on pecan trees in the large orchards of
Thomasville and vicinity.
SOUTHERN GREEN PLANT-BUG (Nezara viridula L.)
Beorgia J. B. Gill (April 5): A few adults of the southern greon stink-bug
have oeen collected on pecan trees since the last week in '.arch.
T7IG GIRDLER (Oncideres cirulata Say)
Louisiana T. H. Jones (April 11): A correspondent from Dubach sent in twigs
GRAPE LEAFHOPPER (Tvyhlocyba cores Harr.)
New Hexico W. E. Emery (April 7): These insects were cau1-ht around the vine-
yard in Dona Ana County, more abundantly on the plant known as
GRIPE SCALE (Ispidiotus uvae Corst.)
Indiana J. J. Davis (April 20): Several reports from southern Indiana
indicate the importance of this scale in some sections.
COTTONY F"APLE SCILE (Pulvin.aria vitis L.)
Indiana J. J.Davis (April 20): Fror recent indications this insect will
again be abundant and destructive tie coming season. Our experience
with the dormant sprays has sho-!n that the insect can be thoroughly
controlled by the use of miscible oils at standard strengths.
SANl JOSE SCPLE ( ?sdidictus rerniciosus Corrst.)
New York C. C. Wagoner (kAril 6): The scale is present rherever observations
were made along the Hudson River in Ulster County. (April 13): A
small arount of scale has been found on Columbia gooseberries in
Ulster County along the Hudson River.
CITRUS AND SUBTROPICAL FRUITS
CITRUS THITEFLY (Dialeurodes citri Ashm.)
Texas T. C. Barber (April 5): At Brownsville damae is slight but in-
creasing. Adults are plentiful in a few restricted lociaities
where they are known to occur.
Louisiana T. H. Jones (April 14): A few adults, the first of the eascon,
were noted today on citrus trees heavily infested with the species
at Baton Rouge.
PANiJVERICfN PLITYPUS (Plat~yus cornositus Say)
Florida w. 1. Yothers (April 5): It may be of interest to entorrolo:ists to
know of a so-called outbreak of ambrosia beetles on oran-e trees
last fall. The species was Platyjrus corrositus, an account of
which is given by Hubbard on pale 14, of Eulletin 7, new series,
of the Division of Entomology, "Sor7e Miscellaneous Results of the
Y7ork of the Division of Entorolo -y." The excessive rains last
surrer raised the water taYle in and around many zroves in reSoto
County. This condition was very injurious to r-any citrus trees
which were planted on the lower locations anr, no dout, has resulted
in the death of some trees. The last of October and first of Noveb. -r
there was considerable interest on the part of (ro-ers in tie arorcsia
beetles, which they claimed were killing their trees. An exarination
showed that the trees were really injured by excessive water and the
beetles had cone in as a second ,ry factor. In rany of the tr -s the
sap was ferrentine at the tire of the visit. W'e reccor-ended i- diate
drainage and other measures to irprove the heclit ard gro-th of the
trees. We also recccrended paintinc of the bodies or trunks of the
trees with undiluted fish-oil soap. It is not known to what extent
the trees have died or 'hat effect the recorrendations have had upon
the further attacks of the oeetl(s.
COTTONY-CUSHION SC/LE (Icer-a urchasi T:ask.)
Texas T. C. Barber (April 5): Dan-age at Bro wville to citrus tr :es is
slight at present. We have observed two restricted areas of infesta-
tion in this locality, but infestation is very li.1t They are
particularly dan erous, however, in view of heavy recent plantin7s
of young trees.
ORC1GE B!SK~T"'OP" (Platoeceticus gloverfi Pack.)
Florida 7. 7. Yotn-.crs (r;ril 5): A serious outoreak of what I deterrined
as the orange basket-orr-n as reported to re. I understood fror. the
reports that this had ruined a crop of V'iencias. This pest usually
follows begarw'eed or so-r other legume, and since the darae had
already been done before the report was sent in, no recorrendations
were given or experiments conducted.
PPPAYA FRUIT-FLY (Toxotryoanra curvicauda Gerst.)
Florida G. F. :oznette (April 5): This species has not been as abundart this
past winter as during forrer winters, and, a-rarcntly, the excessive
drou-bt this past 'inter has ad a deccied influence on this specirs
MANGO SHIELD SCALE (Coccus acuminatus Sign.)
Florida G.F'. Moanette (April 5): This scale has been very abundant this
past winter on mango trees, particularly where the trees have not
been properly sprayed with the oil-emulsion applications during
the winter. This is especially true in groves where Bordeaux
spraying is generally practiced in the bloom which apparently
promotes scale infestation by/the friendly fungi.
DICTYOSPERMUp SCALE (Chrys omphalus dict Vospe ri F.organ)
Florida G. F. Ioznette (April 5): The Dictyospermum scale was abundant
on avocado trees in some nurseries.
PYRIFORM SCALE (Protopulvinaria pyriformis Ckll.)
Florida G. F. Yoznette (April 5): This insect has played the usual amount
of damage in avocado groves.
ORANGE LEAF-NOTCHER (Artipus floridanus Horn) and
CITRUS ROOT WEEVIL (Pachnaeus litius Gerrr.)
Florida G. F. 1oznette (April 5): Has been very abundant in sor-e localities
doing some damage to the young growth of avocado trees in young
groves. In some instances the younZ growth of young Guatemalan
avocadoes was observed completely stripped and the weevils went so
far as to gnaw severely into the young shoots.
AVOCADO LEAF-ROLLER (Gracilaria perseae Busck)
Florida G. F. Moz-nette (April 5): This leaf-roller is commencing to work
in considerable numbers in young groves where trees are putting out
a good spring flush.
AVOCADO BLOSSOY THRIPS (Frankliniella cephalicus Craw.)
Florida G. F. Moznette (April 5): During the latter part of March, as well
as at this time of the year while the avocado is in full bloom and
setting its fruit, this thrips has been exceedingly abundant, and
in a number of localities has materially damaged the bloom. The
Pollock and Trapp varieties and some seedlings reser'bling these
varieties are especially subject to the work of this species. In
some instances it is estimated that the damage to bloom is from 60
to 70 per cent.
AVOCADO LEAF THRIPS (Heliothrins haemrorrhoidalis Bouche)
Florida G. F. Moznette (April 5): During the period when the avocado red
spider is working, this thrips is also to be found in sorre sections
of southern Florida which are favorable for it to carry on its
depredations. These localities are situated generally near the
ocean, bays, or inlet areas. Avocadoes growing on the keys are
more generally attacked by this thrips. This species was abundant
in the above sections during the past winter and the weather conditions
apparently were likewise favorable. This thrips also contributes
to the drain of sap from the dormant foliage and often weakens a tree.
AVOCADO LEAFHOPPER (Emooarca minuenda Ball)
Florida G. F. Moznette (April 5): This pest has been very abundant during
the past winter, especially in those sections whnre proper srraying
was not practiced. It likewise contributes to the drain on the
dormant foliage of the avocado.
AVOCADO RED-SPIDER (Tetranychus vothersi McGregor)
Florida G. F. Moznette (April 5): This mite was unusually abundant in
avocado groves in southern Florida during the past winter. This
was due apparently to the excessive drought and gcnerialy ideal
weather conditions favorable for its deoredations during December,
January, and February. During these months there was a total of
1.64 inches of rain. A number of groves in which control measures
were not practiced showed a great deal of damage and the foliage
was greatly scorched as a result of the work of this red-spid r.
It is essential that the dormant avocado leaves, laden as they
are with stored-up plant food, should be protected from the ravages
of mites, as it is this foliage which matorially sustains the bloom
and aids in the proper setting of the fruit.
AVOCADO VHITEFLY (Triaieurodes f'or~dcrsis Q.)
Floriia G. F. Moznette (April 5): This species is now raking its appearance
in avocado groves with the spring flush of growth.
COCONUT MEALYBUG (Pseudococcus ninae IMask.)
Florida G. F. Moznette (April 5): This mealybug, an enemy of the coconut
palm in southern Florida, is likewise a serious avocado pest in
some sections of southern Florida. It has been very abundant in
southern Florida this past winter and is now working on the young
growth. It also attacks the avocado at the stem end while the
fruit is not setting and at times there is a considerable drop of
fruit from its attacks.
TRUC K- CR 0 INSECTS
POTATO BEETLE (Leptinotarsa deceolinealta Say)
Indiana J. J. Davis (April 20): The potato beetle is on the increase in
the northern half of Indiana.
Louisiana T. H. Jones (April 2): Adults were found in the potato patch today
at Baton Rouge and Denham Springs. This is our first record of
their appearance in the field this year.
Texas F. C. Bishopp (April 23): Potato beetles appeared in considerable
numbers during the latter part of March, but it is doubtful if they
are more numerous than usual at Dallas.
California A. 0. Larson (April 17): Flea-beetles are daaging young potatoes
in the seed beds in the Chino section of California.
California A. 0. Larson (April 17): In the Chino section of California wirc-
wonrs are doin< considerable damage to potatoes and vegetables in
PEA APHID (Illinoia pisi Kalt.)
California Roy E. Carpoell (April 15): Practically the entire 2,150 acres
of cannery peas in Stanislaus County are seriously infested vith
the pea aphid. For two weeks there has been a heavy fli-ht of
winged adults 'ild infestations are found on most of the peas
in tne Santa Clara Valley, and scre late planinr-s are no-" becomin7
Kansas J. W. I'cColloch (Arril 24): The pea aphid has rade its appearance
again in this State, and is causing darae to alfalfa in the vicinit+
of Topeka, Kans. A survey of conditions race yesterday s:ho d that
in one field arproxinately 20 acres are severely injured, and that
the aphids are sreading to adjoining fields, Pea aphids were
also noticed on garden peas near thcse alfalfa fields, and it is
possible that there is sore association betl'een their presence on
garden peas and the alfalfa. This is a rather lare trucking
district, and peas are crown quite extensively. Dr. R. C. Smith,
who made the survey, was inclined to think tiat the dara:e to
alflfa migt be associated with this, since we have had no other
reports of pea aphid injury to alfalfa in the State this year.
California Roy E. Campbell (April 15): All seven canneries in the Santa Clara
Valley stopped canning spinach yesterday because tnere w-ere so rany
syrphid larvae in the spinach which it was impossible to rerrove in
the washing process, and nave got into the canned rroduct.
ARTICHOKE PLUME MOTH (Platvntilia sp.)
California T. D. Urbahns (fMarch 21): P. F. Barnes writes that worrs are
causing considerable alarm and domaging artichokes in the Prroya
Grande district. Adults reared show it to be a plure roth,
Platvptilia sp. Considerable parasitism has been noticed in
material sent to the State insectary.
S O7JTHERN FIELD- CROP INSECTS
CORN-ROOT '"EB"ORP (Crambus calicinosellus Clemr.)
Tennessee Official Record U. S. D. A., Vol. II, No. 14 (April 14i: The
occurrence of heavy infestations of sod web'or:rs in tobacco
fields during the past season has riven an exccillent opportunity
for testing poisoned bait under field conditions, and it Ias benn
shown repeatedly that an ordinary unsveetened roisrned oait
flavored with nitrobenzene is capable of brin-'in. a;rb-t a .or'sl"i-
of from 80 to 94 per cent of the larvae in heavily i 7 .. .
The main species concerned were the tobacco Crarrus ard /.
poreanella Clemens, although it was noted that several ot'iCer S c3
of Crambus larvae were present and were attracted to the bait.
GREEf JUNE DEETLE (Cotinis nitida L.)
Tennessee A. C. Morgan (April 19): This insect is reported ruininS some
beds of tobacco plants.
Kentucky A. C. Morgan (April 19): This insect is reported ruininz some
beds of tobacco plants.
BUD VORP (Helicthis virescens Fab.)
Florida F. S. Chamberlin (April 19): The tobacco budworm has begun to
infest newly set tobacco. This pest is always present throughout
the entire growing season in the southern cigar-wrapper district.
TOBACCO FLFA-BEFTLF (Epitrix parvula Fab.)
Florida F. S. Chamberlin (April 19): Fewer overwintered flea-beetles
have been observed this season than has been the case for the past
several seasons. This is apparently due to effec+ive control
measures practieed by the tobacco growers this past year.
WINGLESS FAY BEETLE (Phvllorha-a sp.)
Texas M. C. Tanquary (April 23): Wingless May beetics, : hich did con-
siderable daiage to cotton in several places in Texas last year,
are reported by M'r. R. R. Reppert as being present in numbers in
northwest Texas near Plainview,
IN SE C T S T T C K ING GREEN H 0 U S
AND ORN A.E NiTAL PLANTS
NARCISSUS BULB FLY (Merodon equestris Fab.)
New York C. R. Crosby (March 3): Specimens have been received. This inscc:
bores long tunnels through the bulbs, causing considerable daxra-e.
The determination was rade by Dr. Johannsen.
A BLACK-HEADED MAGGOT (Sciara hastata Johan.)
Nebraska H. H. Swenk (April 18): In a case of reported injury to house
plants by small b;alk maggote, the culprit when reared proved to
be a Sciara, probably S. hastata Johan.
SOFBUG (Anoadiljidiuwm ul-are Latr.)
Texas F. C. Bishopp (April 23): Reports of s-owbug injury to young garden
stuff and flowers have been received recently from Dallas.
Idaho D. B. Whelan (April 6): Cut off tulips as fast as they core
through the ground.
T-VARKED CUTrTORM (Noctua clandestina Harr.)
Indiana H. F. Dietz (April 18): The W-marked cutworm has been found in
a small planting of Madonna lilies at Indianapolis, eating off the
heavy flowering stalks, which are at this time about 6 inches high.
The entire plant is therefore ruined for the season and a few
insects can do serious damage all out of proportion to their numbers.
CHRYSANTHEUTM GALL MIDGE (Diarthronomivia hvnogaea F. Loew)
Indiana H. F. Dietz (April 23): A number of serious infestations of the
chrysanthemum gall midge have been found in Indiand greenhouses
during February and Earch. These have been the result of the
buying of a large number of plants during the spring of 1922 on
the part of Indiana florists. The plarts came from widely separated
parts of the United States and for the most part were new varieties.
Most of the outbreaks occurred in greenhouses that had previously
been freed of the midge and in which no midges were found in 1920
or 1921. Several cases, however, occurred in greenhouses that had
never before been infested because the florists had not bought any
stock since 1917, until the spring of 1922. All outbreaks this year
were eradicated by spraying the plants with black leaf 40.1 fluid
ounce; fish-oil soap, 4 ounces; and water, 4 gallons, every three
days over a period of six weeks.
FO'REST AND SHADE-TREE INSECTS
GIPSY MOTH (Porthetria dispar L.)
Masaachusetts A. I. Bourne (April 23): There appear to be fewer gipsy moths than
during the last few years.
BROTN-TAIL MOTH (Euproctis chrysorrhoea L.)
Massachusetts A. I. Bourne (April 20): In regard to the brown-tail moth
there is reported a heavier infestation along the Ipswich River
and apparently a maximum abundante in the towns of Boxford and
Ipswich. The general impression is that the pest is increas-
ing markedly over the last few years. (April 20): One
observer in eastern Middlesex County reported finding but three
or four nests on 1,200 young bearing apple trees, which would
indicate at least that the pest, in this particular section,
does not promise to be as abundant as normally.
TENT CATERPILLAR (ealacosoma arericana Fab.)
Massachusetts A. I. Bourne (April 20): In the northern section of the county
the tent caterpillar would appear to us possibly waxing more
abundant every year, as one report states that infestation is
discouragingly heavy, although in some sections not quite as
bad as last year. It is impossible to state just how serious
this will be this season, as none of the egg masses have hatched
yet. In eastern Middlesex County the tent caterpillar is
apparently holding its own, and, judging from the number of egg
masses seen, will be fully as abundant as last year.
FALL CANKERVJOPRM (Alsophila pometaria Harr.)
New Jersey H. B. Weiss (!March 26): Adults are out in large numbers. Eggs
are being laid on shade trees.
LARGER CHESTNUT rEEVIL (Balaninus nroboscideus Fab.)
West Virginia Monthly News Letter, Bureau of Entomology, U. S. D. A., No. 107
(March, 1923): The life history of the larger chestnut weevil,
Balaninus proboscideus Fab., is entirely different from that of

of live stock have been reported. Around packing houses flies
are numerous, this species raking up about 10 per cent of the
