OUTSTiUJDIlIG SL'TTOMOLOGICjIL PSATUPSS IIT THE UlTITEE STATES POP , 1931.
Probably the most serious insect development of the month is the
severe arm^'vvorm oo-tbreak occurring over 11 counties in north central
Texas. A similar outbreak is under way in Mississippi and Kentucky
with lesser outbreai^s in eastern Arkansas and the eastern shore of
Virginia..
Cutworm.s seem to be unusually prevalent along the Atlantic Sea-
board. Tiiese insects are also very troublesome this spring in the
East Central Stakes, and westward to Montana, the Dakotas, and
ITebraslsa. The remainder of the country is experiencing about the
normal cutworm damage.
Earing the first week in May grasshopper,-, eggs were found to be
very numerous in South Dakota and at that time began hatching in
Montana and ITebraslsa. By the third week in the month, hatching was
reported from the Q-reat 3asin. The Salt River Valley of Arizona and
the Antelope Valley and the Klamath Lake district of California a.re
liaving localized grasshopper .outbreaks.
Owing to the cool weather of late spring considerable wireworm
in jury was reported from scattered localities throughout the United
States.
As a v;hole, the Hessi,^ fly situation does not seem to be alarming,
although Illinois reports that from. 32 to 40 per cent of the tillers are
infested in certain fields.
The chinch bug situation in Illinois, Missouri, and parts of
Kansas appears to be rather serious. Large numbers of the bugs are
in tne fields, and in some cases in Illinois are killing wheat, while
in Kansas reports of the killing of a lot of oats by this insect have
been received.
The corn ear worm is commencing to appear in destructive uambers
in the Gulf States.

A very unusual and severe attacle of one of the tiger moths
(Apantesis phalerata Harr, ) is reported from south-central Tennessee,
The Lincoln County agent estimates tliat in that county aloue 500 acres ..
of corn are destroyed, and many pastures are completely stripped of
vegetation.
The alfalfa, weevil is so abundant in western lTeva,da as to'
necessitate control measures.
Luring the latter half of the month codling moth adults were
emerging in the Middle Atlantic States. In the southern part of this
section the emergence is considerably later than last year. In the
Eastern Central States winter survive,! seems to be somewhat higher
tlia,n la,st year, a,nd emergence in this section occurring at about the
same time- as' last year. In the Pacific ITorthwest emergence occurred
during the first week of May, while in California the pealc of emer-
gence in the Antelope Valley was on April 10.
The fruit aphid situation has not materially changed since last
month. T]'..? rosy aphid .a,nd apple grain 8,phid increased slightly in
abunda,nce b award bhe end of the month.
Apple leafhoppers continue to be unusirallj^ numerous in Hew
England, aod are' doing serious damage in the Hudson River Valley in
Hew Yotk State.
A rather unusual outbrealc of the striped cucumber beetle as an
apple pest has developed in Mississippi. This was first observed last
year when this insect, by feeding on the b*l<licsoms, mained a large part
of the crop in the northeastern part of the State, This year the insect
has again attacked the blossoms but not so seriously a,s last year.
The European red mite started hatching during the first week in
May in Hew England and the Middle Atlantic States, Abundance does not
seem to be unusual. ’■
The oriental fruit moth on'^f'^whole .does not seem to be unusually
abundant in its ra/gge this sea, son.
The pl.um curculio is not abnormally abundant throuj'^hout the Hew
England, Middle Atlantic, and 'South Atlantic sections. On the whole
emergence is later tiian usual, and in Georgia the infestation is the
lightest in the past 13 years.
The grape lea.f hopper is unusually abundant in southern
Hew Jersey and in eastern Virginia.
Heavy infestation of pecan by the hickory phj^lloxora was reported
from the Gulf section and this insect was doing serious damage to trees
in Louisiana.
-157-^
The pecan case bearer ^Ya,s very injurious during the first half of
the month in Mississippi and Texas.
The- infestation of the six- spotted mite in Florida, reported in
the last number of the Insect Pest Survey?" Bulletin, is rapidly de-
creasing, apparently oxviug to a fungus disease.
By the middle of the month the striped cucumber beetle put in
its appearance in the southern part of the Middle Atlantic States, and
was recorded as o’uite generally abundant and destructive throughout the
eastern part of the United States, westward to Nebraska, Oklahoma, and
Mississippi,.
The first adult of the spotted cucumber beetle was observed in
Maryland on April 5, and in Kansas on May 19,
Flea beetles on tmuck crops occasioned considerable injury in
Hew York and New Jersey.
Duning the cool weather of May the seed-corn maggot did considerable
damage to bean and cucumber seed in Virginia, to corn and beans in
Illinois, and to similar crops in Kentuclcy, Missouri, parts of Kansas,
and Utah.
The potato tuber worm has been unus'ually abundant in parts of Los
Angeles County, Calif., this year, and was reported from stored potatoes
at Newark, Del.
By the middle of the month reports of serious infestation by the
cabbage aphid were received from New Jersey, Virginia, Ohio, and Indiana.
In some cases the infestations are suspected as having originated on
plants shipped from the South. Very heavy infestations of cabbage by
the cabbage aphid Yvere also reported from Mississippi.
Bather heavy infestations of the harlequin bug were reported from
the southern tip of New Jersej?’ during the month. In the Norfolk
district of Virginia eggs of this insect were numerous in the field
during the last week in April, and the first nymphs were observed on
May 12.
The State Plant' Board of Mississippi reports tliat the strawberry
weevil was found seriously infesting strawberries in the southeastern
part of the State. This is the first record of this insect in Missis-
sippi.
During the last week in May the I'exican bean beetle appeared in
the fields in the southern part of New Jersey, and on the eastern shore
of Maryland, During the first week in the month’ the insect was observed
in the Norfolk district of Virginia. This insect is causing considerable
damage at the present time in North Carolina and has extended its range
southward to Albany, Ga. . Except for the isolated infestation at
Thomasville, Ga. , this is 37 miles south of where it was recorded last
year.
Caiur.cr v.’on.is are reported as sonicrdiat more alDundant than hsual In
the' Hew England States'. 'Sin'i'lar reports have 'been received from
Minnesota and Kansas. ' ' •
One of the worst outhrealrs of the forest tent caterpillar ever
recorded is under way in central Virginia, Complete defoliation of
forest trees lias been observed over considerable areas.
The larch case bearer is 'heavily infesting the larch of Hew
Hampshire, Vermont, and parts of Pennsylvania. Heavj^ stands appear
as if scorched by fire owing to the feeding of this insect.
The European pine sho-ot moth is becoming generally prevalent in
southern Hew England, southern Hev/ York, Hew Jersey, and Pennsylvania.
So far the infestations are all confined to nurseries and transplanted
trees.
The Hantucket pine shoot moth is reported as' doing serious damage
to several species of pine in a nursery in the Philadelphia district of
Pennsylvania.
OUTSTAHDIHC MTOMOIOGICAL PEA.TIJRES IH CAHAPA FOR MAY, 1931.
As forecast, the pale western cutworm has again developed in
outbreak numbers in eastern Alberta e^nd Saskatchewan, affecting grain
crops, and by the middle of May damage was becoming evident. Indica-
tions point to a probable severe outbrealc of the red-backed cutworm in
sections of Manitoba and Saskatchewan, affecting field and garden crops.
The young larvae of this species were appearing in considerable numbers
by the middle of the month. Cutworms are proving troublesome to garden
plants in southern Vancouver Island and in the Okanagan Valley, British
Columbia.
A rather heavy outbreak of white grubs was reported locally from
the Pike Lalie district, in central Saskatchewan. This constitutes the
first record of white grub damage in this territory.
Plea beetles liave again appea.red in large nuinbers on various field
and garden crops on Vancouver Island, in tho Lower Eraser Valley, and in
sections of the Okanagan Valley, British Columbia.
The squa-sh bug is reported from British Columbia for the first time,
specimens liaving been t.3lien in the southern part of the provim e, at
Winslow.
The rosy apple aphid and the apple grp.in aphid are reported as
mimerous amd widespread in the Annapolis Valley, Hova Scotia. In the
Hiagara district, Onta-rio, at the end of April, the s tern mothers of
common species of fruit-tree aphids were noted as apparently less
abijr.da.nt t:ian usual. In British Columbia, reports indicate that
aphids are more ahundant than for F;:a,ny> jears past in southern
Vancouver Island, but tliat th.ey are scarce in the Lower Vraser
Valley. In the latter area ladybird- beetles are unusually abundant.
The San Jose scale is reported as nore coonon in a.pple orchards
of the Niagara peninsula, Ontario, tlian it has been for nany= years.
The hairy spider beetle, ■ an introduced species affecting flour and
other grain products, lias increased rapidly in Manitoba, in recent years,
and is widespread and causing considerable danage,
Tichs a.re troublesome on horses, cattle, and sheep, in south-
centra,! British- 'Columbia, in the range aneas and the Dry Belt generally,
ana cases of tick paraly-sis have occurred, although losses from this
cause are less than lent vear.
Black flies (Simuliidae) appeared earlier tlian us^aaL in. the south-
central sections of British Columbia and* are moderately troublesome.
The cc^ninon cattle grub and the northern cattle grab, particulanly
the latter species, are below norme.l in abundance in British Columbia..

L. U. Peairs (May 27): One report of- akniidance and damage to
corn received from Pendleton County May 23.
H. G. Walker and G. E. Gould '(May 25)-': Several serious "but
localized outbreaks of the arm;)Avorm Iiave been reported in the
past week, , On the Eastern Shore there is an outbreak at Machi-
pungo, with injury to oats, rye, and wheats and at Nassawadox
the damage is serious on oats and wheat. ' In Princess Anne
County damage to oats has been reported.
H. B. .Hungerford (May 7): This species has been visiting
the flowers of fruit trees and lilac at Lawrence in unusually
large numbers this year.
- D. Isely (May 23): Local outbrealcs have occurred in eastern
Arkansas, specimens having been collected in Lee, Arkansas ,
Woodruff, Mississippi, and Prairie Counties.
State Plant Board of Mississippi, Press' Release (May 25);
Hundreds of acres of alfalfa, oats, and other crops in a
number of localities in several Delta counties have been
seriously injured during the past week by worms, according
to letters and telephone complaints. The greatest damage
has occurred in Leflore, Sunflower, and Washington Counties.
Examinations of specimens show tliat several species of insects
are at work, the most abundant being the armyworm. According
to Prof. R. W. Karned, this is the first record in Mississippi
of this insect assuming the army habit, as it is not generally
present in sufficient numbers to be important in the South,
R. W, Earned (May 27): I have just received another report
in regard to the armyworms, probably C. unipuncta, from
Cleveland. On a plantation in Washington Count3^ there was a
20- acre oat field that would probabl’^ have yielded more tlian
60 bushels per acre tliat has been almost completely destroyed.
At the present time the crop is scare elj^ worth harvesting.
The armyvorms had completed their dama,ge within 48 hours after
they V7ere first noticed. The weed, curlj’’ dock, as well as
soy bean and alfalfa in the vicinity of this oat field were
eaten. The leaves on the oats were completely eaten, Tachinid
eggs were noticed on some of the worms. Only ten larvae were
sent in. Pour of them had Tachinid eggs on them. Apparently
something else is also causing the death of the worms, probably
a fujigous disease,
P. L, Thomas (Ma3^^20): An outbreali lias been reported from
eleven counties in zforth- Antral Texas, with injurj^ to oats,
barley, corn, and cotton.

W. B. Noble thro^lgh C. M. Pacloard (May 2): Very light
oviposition occurred from April 17 to 21. The main emergence
apparently liad not yet arrived on April 30.
C. M. Packard (May 2): The spring infestation is expected
to be generally light in the East Central States owing to
small nninbers of overwintering puparia and April weather <
conditions which were rather unfavorable to fly activitj^-.

Redwillow County, in the Republican River Valle3m In
general, the winter wheat came through in good condition,
and the abandonment this spring was very small. It is
still too early to tell how heavy an infestation the
spring brood of the fly will be able to build up this year.
Kansas
H. R. Bryson (May 23); Dr. E. G. Kelly reports on May 1
tliat the Hessian flj^ is plentiful in wheat grown in the

L. A, Stearns (May 21 ): Emergence from hibernation is
considerably delayed. The first emergence from hibernation
at Camden occurred Auril 18. The insect appears to be
much less abundant than it was last year.
F. D. Sanders and C. Graham (May 26): The spring emergence
is later than in 1930 a,nd on the Eastern Shore is m.uch light-
er. It is felt that both the short peach crop last year and
the hot, dry condition of the soil during the pupation period
were unfavor|ible for cUrculio development. Jarring records '
at Salisburyy^930 showed: May 10, 6.7 curculio per tree and
in 1931 on May 13, only 2.65 per tree. 'The season is only
about seven days late as judged by the stag:e of the trees.
Jarring records on curculio indicate heavy invasion of the
orchards about the 16th at Hancock. Most of the records of
heavy infestations come from jarred apple trees.
C. R. Willey (?^ay 25): Tlie plum curculio is very abundant
at Richmond and vicinity. Practically all plum and peach
trees examined were infested, some very badly.
H. G, Walker and G. E. Gould (May 25): The plum curculio
is moderately abundant at Norfolk.
C. H. Alden (May 20): The spring brood of the plum curcu-
lio infestation is light at Cornelia.
0. I. Snapp (’fay 3): This season’s infestation at Fort
Valley is the lightest in 13 years; 18,523 peach drops were
cut on May 7 and 8, and only 402, or 2.2 percent, were in-
fested with larvae’. The infestation last year ranged from
10.6 to 23.5 per cent for the first collection of drops, and
in 1929 the infestabicn varied from 42.7 to 55.0 per cent
for the first collection. The unusually light infestation
this year is attributed to the dry weather during the pupa-
tion season in 1930, the effectiveness of the arsenical treat-
ments in 1930 wlion very little rain fell between the several
applications, and the jarring of the trees to catch the
adult curculios, more of which was done last- year than ever
before. The first larva to reach mat’’urity this season left
a peach drop on May 7. This is 10 dcays later than the first
record last year when only one brood occurred. (May 19):
7,012 peach drops were cut on May 13 and of these only 116,
or 1.6 per cent, were infested. On Ma,y 19 another collection
of 7,678 drops was cut and of these only -70, or 0.9 per
cent, Were infested. The figures further substantiate my re-
port on May S that the curculio infestation in the Georgia
peach belt is the lightest since 1918. Very few growers in
this locality picked up drops this year on account of the
light - infestation, and they v-; ere justified in omitting this
usual practice. Tliere has been no pupation to date (May 19),
although the first larvae entered the soil on ^fey 7. The
continued 'onseasonably cool .v/eather is retarding development.
(May 25): The first pupation of the season took place today.
That is- just- ten days later than the first pupation last year
when the pupation was considered unusually' late. It is ex-
tremely doubtful if there will be a second generation this
year...

R. H. Pettit (May 22): We are still collecting cherry
fruit flies from cages, and there is a vast difference in
the number produced by the different v/ild cherries. I feel
very safe in saying thok the black bodied cherry fruit fly,
(R. fausta 0. S.) breeds by the thousand in the pin cherry,
which is also called the fire cherry, Prunus nennsylvanica.
We have obtained lesser numbers from the other wild cherries
and from some of thc-T"' we have obtained somc.Aafrth'o- rhith-ip
bhudr.5hadult s ■ (R. c ;l h.y:.]. at a Lo ev^ ) as well. I rather think
that the breeding of white-banded specimens in quantity in
wild cherries is a new thing. Probably others have failed
to produce them because they did not collect cherries by
the peck and cage them, over as we did.

all of the last years’ infestations which were practically
cleaned by v/inter 1930.' It is considerably more abundant
than last month on both ornamentals and citrus. The preda-
cious ladybird beetle Ao dolia c a r di nal i s. . Mul s . which was so
abundant last season, has made its appearance in three
separated groves. However, natural establishment and spread
of these predators was not depended on entirely a.nd we have
placed many specim.ens on various infestations this past
month. The scale is not so severe as last year at this time,
probably owAng to the nearly complete reduction of the scale
by the beetles during 1930-.

Field observations indicate that the new Australian mealybug
parasite Cocconhagus 'guerneyi Gompere has carried through the
vrinter in satisfactory numbers and is serving as an important
fo.ctor in holding the mealybug in check this spring. It seems
to be well established throughout the infested areas of the

county owing to the liberations made during the uast two
years from mnitcrial grown in the i>*scctary. Tresent lih-

CYPRESS
CYPPJISS BARK SCALE (Ehrhornia cupressi Ehrh. )
Monthly News Letter, Los Angeles County Agriculture
Commission (April 15); The cypress bark scale and two
species of bark beetles are doing serious damage to
cypress trees in some parts of Los Angeles Codbity, The
cypress bark scale has been found destroying cypress
trees, particularly in hedge rows and ^ind-breaks, in the
eastern and southern parts of the county, and is serious
on trees where it has gained a foothold. The attack of
the beetles is quite heavy in some districts but actual
killing of the trees appears to occur mostly in cases
where the trees are in a weakened condition, due to a
lack of water or similar cultural conditions. Strong
trees are quite successful in overcoming the ’^ork of the
beetles.
