C'JTST.J1ThIT'1r ERNTOMOLOGICZL FST.. IN THE LUT- D STT-.T 3 FOP.. AFRIL,1926

Throughout the Southeastern and Gulf States cut'rorms seem to be unusually
abundant.

The localized green bug outbreaks in the San Antonio section and northern
Texas are now rapidly decree sir.7--.

The army cutworm is doing considerable damage in nor th'T. stern Oklahoma,
and central, westerm, and southwestern Kansas, -'here it is attacking wheat and
alfalfa.

The clover leaf weevil is being reported as numerous in western Illinois
and. northwestern Arkansas.

The various fruit aphids continue to bc reported as unusually scarce
in the Newri.-ln.-r:, MTiddle Atlantic and Ohio Valley States, wTest-ard to
Illinois. In the Southeast reports cf unusual abundance of the rosy apple
aphid have been received from !Tort. Carolina.

The co dling moth seems to have passed the winter in the Middle West
in unusually large numbers. Similar reports have also been received from North
Carolina. Pupation of this insect in the Pacific Northwest is abnormally sarly.

A somewhat extensive account of a new apple pest for this country
(Lecanium coryli L.) appears in this nurher of the Survey Bulletin. This insect
is appearing in serious rulbers in '-estern 'ashington State.

The European red mite is now reported from the Shenandoah Valley of
Virginia. This seems to be the southernmost record for this pest.

The grape leafhopper is so a'-uidip.t in parts of the San Joaquin Valley
of California that considerable sprayis= -"ill be necessary to prevent serious
damage.
Larvae od the painted lady butterfly (reported in the last number of
the Bulletin) are now atta-'inE lettuce and prunes in parts of California.

The turnip vreevil (Listroderes obliouus Gyll.) is reported for the
first time from California. In t'h-e last number of the Survey Bulletin a note
by Mr. Urbahns reported serious infestation in carrot fields and truck gardens
in San Jose. Lt tlhat time the larvae -ere 'lieved to be those of ?'vYp-rr sp.

The carrot rust fly is reported as a pest for the first time from
Massachusetts.

A very early record for smia'e by the Colorado-potato beetle was made
at Ocean Springs, Mis. on March ,29. li-ports of infestation from several
places over the Gulf region -;ere received on and after the middle of the
month.
the
The -e7plant leaf miner in/role of a tomato seed-bed pest is reported
from Sinaloa, Mexico.

From the moss examinations it is evident that the initial boll weevil
infestation in Louisirna w"ill be much heavier than last year and much heavier
in the southern than in the northern part of that State. Mississippi Valley
territory in general may ezpnct frmn a medium to heavy infestation decreasing
to the east--..rdi but with sufficient weevils present to do serious damage
provided sumrmr "feather conditions are favorable. In Texas the weevil population
is so reduced in a large portion of the State that very abnormal weather
conditions -'ould be requiircd to cause serious drsage. It must be borne in
mind, ho-'ever, that these records only indicate the initial emergence of weevils
and the final factor in detecrmining dar'iage will be the summer climatic conditions.
Weevil emergence generally at the different cooperating stations during the
first fifteen days of april has been considerably lewar than was indicated by
the emergence during IMr'ch.

The .u:-rcane borer is abundant enough in the last year's refuse of the
cane crop to indicate a serious infestation this year in Louisiana.

The sand fly (Culicoides punctipennis), has been so numerous in Freestone
County, Texas, as to interfere with laid breaking,

OUTSTIl'III: 7T,,'C.:7OLOGTOCrL rE,7RBES IN C^IT.-. FOP rtPRIL,1926.

The grasshopper situation in British Columbia, during the unusually
hot and dry summer of 1925, 'as the ',orst in the history of the province. If
the summer of 1926 is a dry one, it is feared that there vill be a repetition
of the outbrezas.

The lesser migratory gres-hopper, has greatly increased in numbers in the
Nicola Valley, British Columbia, here it is replacing the roadside grasshopper,
Carnul__ pellucida Scudder. The former species will be the predominant grass-
hopr-r to be dealt with in that section, during 1926.

The 2uro .:-)n corn borer continu.-d to rrreaa in southern Onta.'io, during
1925, t-"..rty-five -.Uitional townships being infestx9.. Over the greater part
of the affected tErritory there '-s an increase in the percenta5,e of infesta-
tion, and in some sections the corn crop ias rendered useless for commercial
purposes and of little value as a farm crop. Further spread a-nd widespread
increase in numlrrs is ex:<-.2ted in 1920.

T'"o million individuals of Habrobrc.con brevicornis 7esm., and fifty
thousand of 'Exorist-s roborntor Frb.,imported European parasites of the European
corn borer,were lib'-rc.ted in southern Ontario during+ the period elapsing bet-een
the spring of 1923 and the au-umn of 1925..

The red-bncked cut7-orm w<..-, the moct important insect pest in Sskctc~c-an
during 1925, and was responsible for 90 to 95 per cent of all cutlorm injury
in the province. A. severe and widespread irnfetation is expected in 1926, but
natural control factors may materially affect the situation.

The pale "-estern cut-'orm extended its range in Saskatchewan during 1925.
In &kbcrta the infestation in 1926 -'ill prob-ably remain statiornar:'.

Euxoa excellens Grt. is one of the most troublesome cut-orm species
on the coast of British Columni. .

'ire-'orms v'ere a serious p.st in Saskatchervan and Alberta, and locally
in Manitoba, during 1925. They ap,-ar to belincreasing in numbers and extending
th-ir range in alberta.

The rose leafhopper is becoming of major importance as a pest of apples
in many sections of the O1mngr.n V:lley, British Columbia. It was epidemic
in many orchards in Ne' Brunsi-ick during 1925.

The cottony peach scale, Pulvinaria .mrdr'1li, appears to be generally
distributed throughout the 7Tigara fruit district, Ontario, but not in injurious
numbers.

Outbreaks of the aprle mag-ot occurred in sections of Nova Scotia during
1925. This species also apoearq to be on the increase in NTe- Brunswick.

An outbreak of the fall c3n':dr-cr1 is expected in the Annanolis Valley,
NTova Scotia, during 1926.

Slugs appear to be on the increase throughout the St.Johnn River Valley,
New Brunswick, where they attacked n'.r.crous varieties of garden andgreenhouse
plants during 1925,

The satin moth was found in two new localities in British Columbic during
1925, at Courtenay and at Sydney.

R W. Harned (April 2): Specirrens of cutworms collected from
tomatoes at lDurant have been identified by ",b. S. E. Crumb
of the Bureau of Entomology, Clarksville, Tenn., as this
species. The same species 7as also collected near English
pea plants at Holly Springs, :isc. Although complaints in
rez-ard to cutworms have been received from many places through-
out the State, especially from Copiah County, the specimens
mentioned above are the only ones we have so far received.

W: E. Hinds (April 24): Cutworms have been unusually abundant
and injurious to garden crops and to strawberries particularly.

M. H. Swenk (April 25): Cut"orm- were found actively working
in the soil in fields being plowed on April 17 in Boone County.

B. G. Thompson (MU.-ch 24): Eg-s of the variegated cut'.'orm,
Lycophotia margaritosa Haw., were observed in a field at
Corvallis on March 12. Ez.-. hatched on March 24. Nearly full
grown larvae were numerous. A few adults were observed as early
as March 1.

C:IT7H BUG (Blissus leu-c.- ,-ruc Say)

W. P. Flint (April 20): The weather has not been sufficiently
warm to cause a or7ener-l flight of chinch bugs from hibernation
even in the south-central part of the State. Bugs have been
active in hibernating quarters and very few observed flying
on Mar ch 19.

TT. H. Swenk (April 25): The chinch bugs prove to have wintered
with comparatively slight mortality over southeastern 1Tebras1 ,
and by the middle of April were becoming active in large
numbers in their hiV-,_rri-iting retreats.

J. W, McColloch (April 19): Chinch bugs were flying in large
numbers on April 17. This the first markl-. flight of the
year although some bups have been moving since the middle of
March.
GREEN BU- (Toxontera crrinum Roni.)

C. E. Sanborn (April 1): Grjcn bugs have been prevalent all
winter but no serious outbreak has or will occur. a heavy
snowstorm recently prevailing throughout the State may aid. them
some from the standpoint of propagation by preventing inimical
insect control, but I consider it most too late for the green
bug to do much damage.

examination of one field of about 15,000 hills, I believe a 50
per cent infestation would be a very conservative estimate. I examined
7 hills and found them to contain 2,4,11,2,4,5, and 5 larvae res-
pectively. i.-..y of the larvae -,ere well up tow-ard the tas-el end
in the old st:2':c. The larvae are beginning to become lively and were
crawling into uninfested portions of the sta&lls.
A casual examination of old stalks which had -en washed in by the
high water revealed many larvae. On plots 1"here the corn had been
cut last year I fcu-r.d hardly a larva. Cornstalks are scattered all
over the farm, in the manure piles and fields and around hotbeds.
It might be of interest to note that corn and broom corn have been
grown on these flats probably for the past 50 years. With the exception
of 1919 no definite plan of eradication work has ever been attempted
in this area.

ALF ALFA

"iCUTD BUILDING PRAIRIE ATt (Pqo.onromrm-Tm occidentalis M-i-an-)

J. W. McColloch (April 1): This ant is reported abundant in a 20-
qcre alfalfa field at Windom, and is ruining the stand.

PEA APHID (Illinoia pisi Kalt.)

J, W. McColloch (April 20): A hecsv: infestation of the pea aphid has
developed in an alfalfa field at Belvidere. The plants are turning
yellow and dying down.

Sadie E. Keen (April 3): This insect was present in damagi n numbers
on several fields of vetch in an isolated side valley of the Willa-
mette near Wapato. A fair percentcts of the aphids were attacked by
EntomoPhthora aphidis, and syrphid. larvae were also present.

CLOV-.

LOV. LEA'7, V-VIL (:Hyncra punctata FYab.)

W. P. Flint (April 20): Mr. J. H. Bie-er reports finding one adult
of the clover leaf weevil in a clover field in vrestern Illinois.
Larvae, mostly very small, are numerous in clover, alfalfa, and sweet
clover fields throughout the State.

Dwight Iseily (April 22): The clover leaf weevil is quite common this
year in the vicinity of Fayetteville. Weevil larvae are not abundant
enough to cause what might be considered an outbreak, but their
occrrence in any numbers is -nutaLl. Ordinarily they are a curiosity
in this vicinity.

the State as a whole that 3prle plant lice are considerably
reduced in numbers over last Seasonr., except for a few cases in
individual orchards whero for sone reason or other there happens
to be a considerable abundance, There is every inaicaticn that
orchard plant lice will not be a serious factor this coming
season.

W. S. Hough (April 16): lIone of the three species of aphids,
Anraphis roses Brker, RhoraIcsinhum orunifoliae Fitch, and
Aphis poni DeG., -;hich usually appear on apple trees have appeared
this season. Only two rosy apple aphids have been found to
date and but two nymphs of horaloTnhirnm prunifoliae Fitci have
been observed on the pnnie buds. Between $12,000 ar.d $15,000
worth of nicotine sulphate is usually used in the delayed dormant
spray in orchards near Winchester, but this year the delayed
dormant spray was applied without nicotine.

W, E. Rumsey (April IS): Aphis eTms, all species, are very
scarce about Morgantown and also about Charleston, Kana-ha County.
In the eastern panhandle none of the Station men have teen able
to find any aphid eggs on the apple trees in Berkeley and Jefferson
Counties.

Bennet A, Porter (April 27): All species of apple aphids are
almost totally absent from the orchards at Vincennes. To aphids
have been seen except a half dozen individuals, which were probably
the green apple aphid.

W. P. Flint (April 20): IF-:-inatiorOof apple trees in the cluster-
bud stage in southern Illinois orchards have failed to rcveal
a single aphid of any species present. The same is true of central
Illinois, where the trees are just showing green tips. It seems
certain that aphids will be very scarce in Illinois apple orchards
this season.
APPLE APHID (_hs pomi DeG.)

Ernest E. Cory (April 2): The green apple aphid hatched at College
Park on Narch 27.


ROSY AFPLE AHI-D (Antraphis roseus Baker)

T"orth Carolina Z.P. 'etcalf (March): The eggs of what appears to be this species
are nmuch more abundant in the mountains of the State than durinE
the a-erc-e season.

Cr-' on Don C. Mote (March 19): Stem mothers -itlh small colonies were
first observed on this day on the developing cluster buds. All

,,ill be considsr-ble trouble from this insect if the -eather
of the spri:. is fpvorable to its increase.

E.J.iIer-conf-r (April I): Cn account of the very early season
nearly 10 per cent of the wintering :odling moth larvae have
puT ted by April 1 in the Yakima Valley. The season is fully
Th:*:e -'e-_ks ahead of normal on this date. In the spring of 1925,
about 50 individuals of the codling moth parasite A-:o:- _tcr
c.r 'n: ee Vier.. ,-ere libenate in an orchard in 1-hich :.o
parsites had previously occurred. An examination of 'rorms
in this orchard, made late in Mlarch,1926, sho-red a parasitism
of approximately 6 per cent.

Harold Morrison (March 31): 'n July,l924, specimens of this
insect were received for determination from Frof. Tre'-or
Kincaid of the University of Wash ington, Attention 7as called
to the fact that this was the first Iknown record of the present re
of this coccid in the United States. In March of this -:e-.r
further speci:ntns were received from th., same cource with in-
formation that showed clearly that the pest is *...ll ,-t.hblished
in Seattle at least.
In the Canadian Insect Pest Review, Volume 2, ro. 4, July,
1924, an important outbreak of this insect on shade trees
in Stanley Park, Vancouver, B.C., was reported. The insc-ect
7as recorded from male, horse-chestnut, lime, mcu-tain ash,
laurel, hawthorn, and rasrpberryv. In the Arril number of the
same publication for 1925 it is recorded as havirg first e en
introduced in Stanley- Park in t'L-. fall of 1923.
In the W-stern Planit quarantine B*O:rd IT-D- Letter, o.5,
May,1925, is a note to the effect that this insect was intro-
duced to Vancouver on nursery stock from -urcre more than 20
years n-o, that it was fairly successfully exterminat+ej in
1910, but that unfortunately infestation had spread to some
wild rro'-th near by, resulting in th'- .-raiual incre'--e of

This insect :was reported from the North American Continent
more than 25 yearsago from Nova Scotia.

R. L. Webster (April 21): I am sending you samples of a
Lscan'im which has this year become very abundant on the West
side. A letter from Arthur Frank, Plant Pathologist, at the
Western Washington Ep criment Station, Py:llup, says: "We
are simply overwhelmed with inquiries about the Lec'r.iurm scale
at this time. We',7 have always had an infestation of these in
the orchards east of la'ie Washington opposite Seattle from
"-hich we have heard for s,.erul years. Hcvcwevor, this season
the pest is appearing in unprecedented numbers and severity.
The same situation exists in Whatcom County at Bellingham.

EI]EOErT R-ED Mii. (Paratetranychus pilosus C.& F.)

A.I.Bourne (April 23): The Euro-un red mite appears to be
rather more abundant than ever, particularly in the eastern
sections of the State, with apparently a particularly heavy
infestation at various points in Essex County.

Theron P. Remy (April 25): 7nilo visiting the orchards in
the Sbenandolh Valley the European red mite was noted at
Waynesboro, Va. ,in several apple orchards. Ad it is not re-
ported from that far south I thought it might be of interest.
This was verified by Mr. Hough of the Winchester Va.,
Laboratory.

W. S. Abbott (april 26): The eggs of this mite were very
abundant last spring (1925),but none could be found this
spring (1926) at Oaiton. No special treatmen-t for this mite
was applied.

E.J.Newcomer (April 1): Winter e_.s of the European red mite
began hatching at Yakinm on :'lrdh 28, about two meeks earlier
than last year. Ordinarily hatching begins about the middle
of April. UBRAR

Stat -.-.:-nt


R.W.Leiby and assistantss (i.,'-il 13): .'-'il mortality was
'pr rntly he:rvy durin- t`.- -.-t winter if hibernation survival
is a fair index. In early Nove:mber,1925, the .-ycr-3 population
alive per ten of -,oss is three localities '-as 552 with none
dead, the mi..i.1.um bein" 1,293 and the minimum 114. In Fe'!:ruary
and 'March,1926, two localities s'-.o'od an avers.re of 9) weevils
per ton of moss and not a single one alive.,

...am and. S.ros.ithrough ".:.5c-r: Since late summer
eitherr conditions favored a new =-:o-owth of cotton fruit thrcurh-
out the greater 'oart of the cotton--ro'ing arc i in the State,
an abunl-nt food su:'oly waas aavilable for the great nu'.ber of
',eevils present in all fields. Consequently, numerous veevils
'"ere fitted for successful hibcrn.: tion. Cool 1-eather of some
duration forced the "eerils into rather secure quarters for the
I"inter and it is problematical whether or not the more severe
cold snaps of later date have had, the usual effect of consider-
ably thin.i.g them. At pris;.nt there ,prV:ar to be no active
-2eevils about.

'W.E.Hinds (Aporil 24): During April the em.'-:T.cc of the boll

2 nor cent of the 13,000 -eevils placed in hibernation c-._es

.these records morg widespread in their oTlinatniop. AS usu-)I these
ey minations have be!n maade only in Sr>sh moss and t findings
arc roc6rded .in -live -,eevils per ton of moss,. The records from
the bcgi.1ning of this r,_ck to last year are sho7n, in the follo-ing

During the present -Ainter still more .points have been
included wvith the idta of developing within the next few ye-rs
a selected, series of localities r'preoentative of the different
districts of the Cotton Belt. This seasons examinations were
distributed throughout Louisiana from the south to the north
at perhaps 50 different points so that a fai-rly representative
average' condition is reported. Ia the southeast ano-h.jr group
of points '-as selected: in Georgia and still another in South
Carolina. The following are the figures secured during March,
1926, at these various points:
.ive "eevils
State per tot of moss
Louiisiana-- ---.. 43
Georgia ------ -2
South Carolina -- - 7

In contrasting these figures with past years, it should be
rcme'fnen_:cd that the inclusion of new points prevents an absolutely
accurate comparison, but theso records do indicate something
of what iay be expected in the amount of ,weevils coming from
hibernation. For e::,mnple, it is obvious that the initial infestation
in Louisiana will be much heavier than last year, It -ill be very
much heavier in southern Louisiana than in the northern 'art of
the State, but the yr-ar-to-year contracts remain the same, and
aprar'ntly, in the State a. a, "hcle, 17e. cn expect at least a
normal infestation.. Spotted conditions may be expected owing to
the irregular distribution of leaf worm defoliations last fall.
In the Southeast, the Georgia points examined extend across
the coastal plain section and thus' reorescnt a territory in i'hich
the weevil crop was co-paratively.-light last fall. :-1s -as










illustrated by the early fall examinations for -eevils entering
hibernation. The same remarks apply to South Oqrolina where the
evanminations were maae along the coastal section of the State
extending as far north as Florence. Under the circumstances, it
seems probable that the Southeastern States -.rill have a fairly
light infestation at the outset but still amply sufficient to cause
serious crop dcmoge with normal rainfall during the growing months.
Alabama and Mississippi may expect a very spottr:d infestation probably
averaging heavier than Georgia and South Carolina but lighter than
Louiaiana. In Texas general prospects indicate a comparatively
light initial infestation at practically all points except along the
Gulf Coast. To summarize, the Mississippi Valley territory, especially
in Louisiana, may expect from a medium to a heavy infestation, de-
crdasing to the eastward, but with still sufficient --e-vils present
to do serious damage provided summer weather conditions are favorable
for the weevils. In Texas the weevil population is to reduced in a
large portion of the State that it would require very abnormally
unfavorable weather to cause serious damage but the remainder of
the State, particularly along the Gulf Coast, apparently has a more
or less normal condition.
As has been pointed out in connection with past reports, these
records only indicate the initial i-mprgence of weevils from hiber-
nation and the final factor in determining the damage "'ill be the
summer climatic conditions. Certainly, some sections now face a very
serioiz infestation and the vast majority of the cotton area has at
least a normal crop of -eevils. In other words, the climatic con-
ditions so unfavorable to- the weevil during the past two years have
been very largely overcome nd the farmer should prepare himself
for a vigorous cnmrai-n to reduce damage to the minimum.
(April 1) The folloinA records indicate the percentage of 'ucevil
emergence 7rior to Aoril 1 at the various points where hibernation
ca-es'are under observation:
At College Station, Tex., jmr-apence records are available at
several near-by points for the years 1906,1907, and 1908. At these
points an average of 2.44 per cent of the weevils emcr-ei prior
to April 1 and at College Station 1.96 per cent emsr.'.d last year
compared dith 2.45 per cent this year.
At Tallulah, La., an average of 0.22 per cent of weevils emerged
during March for the last ten yc-.:irs. Last year 0.01 per cent emerged
during the same period while e this'- year 0.02 per cent emerged.
At Baton Rouec, La., during March last year 1.64 p:- cent of the
weevilss um2rgcd compared with 0.80 per cent this year.
At Cl.-mcon College, S.C., 0.55 per cent em-rgcd last year com-
pared with 0.05 per cent this year.
At Florence, S.C., in 1924 during March 0.3 per cent of the
wrecvils emerged, in 1925 during the same period 1.0SO per ccnt, :r.l
this year 0.04 per cent cmsrzed.
At Exp-im-n"t, Ga., prior to April 1 last year 0.40 per cent
of the -'ccvils merged compared with 0.02 per cent this year.
At Poplarville, Miss., 0.05 per cent emerged during March and
no 1',ce-'ils "'-re reported to have merged in the cages at the other
points in Mississippi. At Holly Springs no weevils had emerged
to the same date last year.

Records during the lst ten years at Taliulah, La., sI'ow that
on Aprill 1 an average of only 17 per cent of the total cmrnr e

the present -c:.;son has so far "*.:r unfavorable for mergence

Consequently, rhilu it is still too early to predict the final

(.pril 16): weevil emergence -onerally at the different

con-iderably lo-"er than was indicated by emergence during Mvarch.
As -'as pointed out in the last report at Tallulah, La., for the

todv place during March Th ile an *^',craa of slightly more than
22 pzr cent occurred during April. In other -ords, past records
:- Talulah inlicate that -mergence during April -as considerably
higher than in 'a.rch. The slo- emergence this year was undoubt -dly
caused by the unfavorable weather conditions "jhirb prevailed at
most of the cooperating stations during the last 15 lays,
At several points near College Station, Tex., in 1906,1907,
