Vol. 11 June 1, 1931 No. 4


Probably the most serious insect 'development of the month is the
severe armyworm outbreak occurring over 11 counties in north central
Texas. A similar outbreak is under way in Mississippi and Kentucky
with lesser outbreaks in eastern Arkansas and the eastern shore of

Cutworms seem to be unusually prevalent alonz the Atlantic Sea-
board. Thcse in-ects are also very troublesome this spring in the
East Central States, and westward to Montana, the Dakotas, and
Nebraska. The ret .in-ei- of ths country is experiencing about the
normal cutworm duir"e.

During the first week in May grasshopper, e--s_ were found to be
very numerous in South D1kota and at that time began hatching in
Montana and 1ebras?.a. 3y the third week in the month, hatching was
reported from the Great Basin. The Salt River Valley of Arizona and
the Antelope Valley and the Klamath Lake district of California are
having localized grasshopper outbreaks.

Owing to the cool weather of late spring considerable wireworm
injury was reported from scattered localities throughout the United

As a whole, the Hessian 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 apprears to be rather serious. Largo numbers of the bugs are
in the 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 receivCed.

The corn ear worm is commencing to appear in destructive numbers
in the Gulf States.



A vry unusual and severe attack of one of the tiger moths
(Apantesis phalerata Harr.). is .reported. from south-central Tennessee.
The Lincoln County agent estimates that in that county along 500 acess -
of corn are destroyed, and many pastures are completely stripped of
vegetation. . ... ............

The alfalfa weevil is so abundant in western Nevada as to
necessitate control measures.

During the latter half of the mionth;'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 .survival seems to be somewhat higher
than last year, and emnergence in this section occurring at about the
same time as last year. in the'Pacific Northwest emergence occurred
during the first week of May, while in California the peak of emer-
gence in.the Antelope Valley was ..on April 10.

The fruit ,aphid. situation has not materially changed since last
month. The rosy aphid and apple grain aphid increased slightly in
abundance toward the end of the month.

Apple leafhoppers continue to be unusually numerous in New
England, and are doing serious damage in' the HuTids6.ri River Valley in
New York State..',

A rather unusual outbreak of ithe striped cucumber beetle as an
apple pest hIas developed in Mississippi. 'This wa's first observed last
year when this insect, by feeding on 'the blssomsz; ruined 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 as last year.

The European red mite started hatching during the first week in
May in New England and the Middle Atlantic States. Abundance does not
seem to be unusual.

The oriental fruit moth ont whole does' not seem to be unusually
abundant in its range this season.,

The plum curculio is not abnormally abundant throughout the New'
England., Middle Atlantic, and South Atlantic sections. On the whole
emergence is later than usual, and in Georgia the infestation is the
lightest in the past 13 years.

The grape leafhopper is 9POrteas unusually abundant in southern
New Jersey and in eastern Virginia,.

Heavy infestation of pecan by the hickory phylloxera was reported
from the Gulf section and this insect was doing serious damage to trees
in Louisiana.


The pocan case bearer was very injurious durinT thie 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 owirng to a funa.-uz 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 quite generally abundant and' destructive throughout the
eastern part of the United States, westward to Nebraska, Oklahoma, and

The first adult of the spotted cucumber beetle was observed in
Maryland on April 5, and in Kansas on May 19.

Flea beetles on truck crops occasioned considerable injury in,
New York and New Jersey.

During the cool weather of M.ay the seed-corn Tnazot did considerable
damage to bean and cucumber seed in Virginia, to corn and beans in
Illinois, and to similar crops in Kentucky, Missouri, parts of Kansas,
and Utah.

The potato tuber worm has been unusually aburlant in parts of Los
An-geles 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 "Tcr', Jersey, Virginia, Ohio, aind 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 were also reported from Mississippi.

Rather Ucavy infestations of the harlequin bug were reported from
the southern tip of :T7ewv Jersey during the month. In the Norfolk
district of Virginia eg.-s 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 that 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-

During the last week in Ma- the Mexican bean beetle appeared in
the fields in the southern part of New Jersey, and on the eastern shore
of Maryland. During the first w6ek in the r-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 ran-e
southward to Albany, Ga. Except for the isolated infestation at
Thomasville, Ga., this is 37 miles south of where it was recorded last


Caniker worms are. reported,as ,so!c'.'hat more abundant than usual In
the New England States. Similar reports have been received from
Minnesota and. Kansas.

One of the worst outbreaks of the forest tent caterpillar ever
recorded is under way in central Virginia. Complete defoliation of
forest trees has been observed over considerable areas.

The larch case bearer is heavily infesting the larch of New
Hampshire, Vermont, and parts of Pennsylvania. Heavy stands appear
as if scorched by fire owing to the feeding of this insect.

The European pine shoot moth is becoming generally prevalent in
southern New England, southern New York, New Jersey, and Pennsylvania.
So far the infestations are all confined to nurseries and transplanted

The Nantucket pine shoot moth is reported as doing serious damage
to several species of pine in a nursery in the Philadelphia district of


As forecast, the pale western cutworm has again developed in
outbreak numbers in eastern Alberta and Saskatchewan, affecting grain
crops, and by the middle of May damage was becoming evident. Indica-
tions point to a probable severe outbreak 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

A rather heavy outbreak of white grubs was reported locally from
the Pike Lake district, in central Saskatchewan. This constitutes the
first record of white grub damage in this territory.

Flea beetles have again appeared ini large numbers on various field
and garden crops on Vancouver Island, in tho Lower Frasor Valley,and in
sections of the Okanagan Valley, British Columbia.

The squash bug is reported from British Columbia for the first time,
specimens having been taken in the southern part of the province, at

The rosy apple aphid and the apple grain aphid are reported as
- numerous and widespread in the Annapolis Valley, Nova Scotia. In the
Niagara district, Ontario, at the end of April, the stern mothers of
co-r-'-n- species of fruit-tree aphids were noted as apparently less

-159- than usual. 'In British Colu-ibia, ,reports indicate that
aphids are more abundant than for rany years past in southern Islard, but t>.2t they arc very scarce in the Lower Fraser
Valley. In the latter area ladybird beetles are unusually abundant.

The San Jose scale is reported as more common in apple orchards
of the Niagara peninsula, Ontario, than it has been for r.any years.

The hairy spider beetle, an introduced species affecting flour and
other grain products, ias increased rapidly- in Manitoba in recent years,
and is widespread and causing considerable dunage.

Ticks are troublesome on horses, cattle, and sheep, in south-
central British Columbia, in the range areas and the Dry Belt generally,
and cases of tick paralysis have occurred, although losses from this
cause are less than last year.

Black flies (Simuliidae) appeared earlier than usual in the south-
central sections of British Columbia and are moderately troublesome.

The common cattle grub and the northern cattle grub, particularly
the latter species, are below normal in abundance in British Columbia.

S ARMYWOR (Cirphis unipuncta Haw.

L. M. Peairs (May 27): One report of abundance and damage to
corn* received from Pendl eto0n County May '23.

H. G. Walker and G. E. Gould (May 25): Several serious but
localized outbrea2Ks of the armyworm have been reported imn the
past week. On the Eastern Shore their' is an outbreak at Machi-
pungo, with injury to oats, rye, and wheat, and at Nassawadox
the dama-e 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 outbreaks have occurred in eastern
Aransas, 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 that several species of insects
are at work, the most abundant being the armyworm. According
to Prof. R. W. Earned, 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. Harned (May 27)t I hav6 just received another report
in regard to the armyworms, probably q. unipuncta, from
Cleveland. On a plantation in Washington County there was a
20-acre oat field that would probably have yielded more than
60 bushels per acre that has been almost completely destroyed.
At the present time the crop is scarcely worth harvesting.
The armyworms had completed their damage within 48 hours after
they were first noticed. The weed, curly 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 thle worms. Only ten larvae were
sent in. Four of them had Tachinid eggs on them. Apparently
something else is also causing the death of the worms, probably
a fungous disease.

F. L. Thomas (May 20): An outbreak has been reported from
eleven counties in *eorth-6*entral Texas, with injury to oats,
barley, corn, and cotton.

Tachina e-gs were counted on a single ppcien.

South Carolina P. K. H?.rr son (nay 19): CGt'v.'orvr have been doing some
injury to small pa r'cn plants at Fairfax, and have been very
troublesome in orr yard, cutting especially car.-,,santhemuim and
pc tunia plaints.

Ohio T. H. (Ma.y 7): Clibim'n-cutror.s of this species
(Agrotis unicolor Walk. ) have bcen devourin. leaves, and

up the trees at night and defoliate the branches and twigs
.*on-the inside of the trees. Many trees have the upper limbs
:* also defoliated. (May 24.) Cutworms are now quite serious
in. some corn and tobacco plantings in southwestern Ohio.
They are much more abundant than last spring.
:J. J. Davis (May .26): Outworms are common throughout the
State and attacking all kinds'or vegetation. They are
apparently more abundant than for several seasons.

W. P. Flint (May. 19): The riristly dutworm (Polia renigera

Morton, Burleigh, Wells, Kidder, Lacoure, and Dickey
but in all counties has caused injury to such crops as
rye, alfalfa, sweet clover, and March-sown wheat.

C. J. Dra'ee (May 8): Cutworms are present in a large number
of alfalfa and clover fields this spring. They seem to be
doing a considerable amount of damage.

H. E. Jaqtes (May 25): Cutworms are very abundant in the
so".thc. stern part of the State, and generally moderately
abundant over the remainder of the State.








i Easeanan (1 ay 23): -Worms pup; ting from May 15 to

prevalent and rather geiprally distributed. Western T'qn-as
has suffered considerably.

C. M. Pack7ard (l'ay 2): C. Benton reports much injury to
youn': corn by cutwoorms associated with an arctiid moth out-
brc-1:, from April 20 to 30. Tentatively identified as

injury to corn near Harrisburg. (Determined by J. A. Hyslop.)

K. L. Cockerham (May 30): Injury by Heteroderes laurentii
Guer. to the commercial sweetpotato crop this spring is far
greater than at any time since this species was discovered in
southern Alabama. Many plantations have 50 per cent of the tubers
damaged and the Bureau of Nar-c:ts' Inspectors report that 25 per
cent of the crop on shipping platforms during the week of a7y
23 to 30 was darn@aed.

N. L. Douglass (May 19): Wirce..' :rr-s have been re rttod
injuring corn on low bottom land in Mont;onr,-'ry County

E. 0. Essig (May 22): Wireworms are moderately abu.dat
in the Delta of Sacrz.crnto River.


WHITE GRTUBS (Phyllophaga spp.)












A. I. Bourne (May 23): Several complaints have been
received of white grubs working in tobacco seed beds in
Amhderst. In cv-er: case it has been' found that the insects
are small, young stage grubs.

R. B. Friend (May 18): Adults of Phyllophag tristis
Fab. are very abundant in lawns in Old ILyme.

SH. I. Worthley (May 20): Adults are now common about
lights and in.bait traps, at State College.

A. B. Champlain (May 27): June beetles were observed
in a very heavy flight in the vicinity of Harrisburg on the
evenings of May 15 and 16.They have not been observed since
that time.

J. A. Hyslop (May 5): Adult beetles are completely
defoliating five ornamental European mountain ash that
were set this spring in recently plowed sod land at Avanel.

H, G. Walker (May 25): June beetles seem to be common
throughout the Tidewater region and are reported to be
causing damage to many trees and shrubs.

J. B. Gill (April 28): May beetles have been observed
during April eating the buds and tender shoots of pecan.
trees in some orchards in the vicinity'bof Putney.

E. W. Mendenhall (May 25): May beetles are very numerous
in Columbus and vicinity and some complaint that the beetles
were eating the leaves of plum and other fruit trees has
been received.

J. J. Davis (May 26): White grubs are among the out-
standing insects according to correspondence. For the past
month they have been reported very abundant in ground being
plowed. Apparently in most cases they are of the brood
which will mature this year.

W. P. Flint (May 18): C. C. Compton reported adults in
flight in considerable numbers in Carroll County on April 18.

W. A. Price (May 25): White grubs are moderately abundant
on corn and tobacco. (May 27): Adult May beetles are very
plentiful about lights at nights, in Lexington.

R. H. Pettit (May 25): White grubs are very abundant.







C. L. Fluke (:., 7): A peculiar situation exists in
Wisconsin in regard to the api:.pearance of June beetles which
at present we are not able to explain. According to our
information the spring of 1932 should be the logical tine
for appearance of the main brood of adults. However, this
spring there has already been a heavy flight of beetles.
They began appearing as early as April 13 eid it seems as
if the- are beetles which should have appeared next year.
We believe that the long continued hot weather of last
year caused these insects to develop in two years, which
is apparently going to upset the brood cycles. From our
counts about 50 per cent remained as larvae over to this
year. There are approxi:..ately 40,000 adult beetles per
acre in the generally infested territory of south western
Wisconsin. This refers of course to the pasture land.

A. G. Rug:-les and assistants (May): White grubs were
quite generally reported as but moder-tely abundant or scarce
throughout the State. iTo reports of unusual ab.:.3:.ce were
received. (Abstract J.A.H.)
H. E. Jaques (May 25): TWhite grubs were reported as
scarce in the following Counties: Sioux, Harrison, Page,
Dickinson, Buena Vista, Adams, Bnmet, and Worth; -oderately
aburd.-i:..t in Crn .', Pocahontas, Union, Tana, lie roe,
Maraska, Van Buren, Henry, Delawlare, Jones, Cedar. Des IMoines,
and Jackson; very abundant in a.ynt, Keokuk, and BZachanan.

L. Haseman (May 23): White grubs are moderately abundant
at Columbia. Flights of beetles were observed on '-arm nights
about the middle of the month.

M. H. Swenk (April 15 May 15): The first May beetles
were found on the evening of April 29.

R. V7. Harned (May 25): Specimens of Ma' beetle- identified
by J. M. Langston as P.bipartita Horn and P. prac'termissa Horn
were reported as injuring roses at Canton'on .ay 18.

H. Dietrich (May 23): Adults did some injury to pecans at
Lucedale early in the month.

X. L. Douglass (May 19):' M.:- beetles have been numerous
in Grenada, Y?.lobusha, and 'Iont- :omery Counties this spring,
injuring pecans, roses, and other tender growth on plants of
a similar nature.

HESSIANT FLY (Phytophaga destructor Say)

W. B. Noble through C. M. Packard (May 2): Very light
oviposition occurred from April 17 to 21. The main emergence
apparently had not yet arrived on April 30.

C. M. Packard (May 2): The spring infestation is expected
to be generally li,-iht in the East Central States owing to
small numbers of overwintering puparia and April weather
conditions which were rather unfavorable to fly activity.

J. H. Bigger through W. P, Flint (May 18): The Hessian
fly is very abundant. From 32 to 45 per cent of tillers in
certain fields were infested with eggs on April 22, in Greene
H. E. Jaques (May 25): The Hessian fly is moderately
abundant in the southern half of the State .and there are
reports of great abundance in Woodbury and Thma 'Counties.

L. Haseman (May 23): The Hessian fly situation seems to
be not at all serious anywhere in the State.

M. H. Swenk (April 15- May 15): The western limits of
the present infestation seem to be Gothenburg, Dawson County,
in the Platte River Valley, and a little west of McCook,
Redwillow County, in the Republican River Valley. 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.

H. R. Bryson (May 23): 'Dr. E. G. Kelly reports on May 1
that the Hessian fly,'.is plentiful in wheat grown in the
northern tier of counties in the western half of the State.
These comprise several excellent corn-growing counties.
C. Benton through C. M.- Packard (May 2): Light egg
laying occurred throughout April, the main wave from April
18 to 21, but not heavy. Small to mature larvae were present
April 28; in the most heavily infested fields about 20 per
cent of the stems are infested, two larvae to a stem.

Oregon Agricultural College, Insect Pest Report (March):
First emergence of the spring brood of the Hessian fly
occurred March 19.

CHINCH _UJG (Blissus leucopterus. Sa:)

W. P. Flint (.'y 19): The weather during early May was
rather unfavorable to chinch bugs and a slight reC.ction
in numbers occurred. TIis reduction, however, was not
sufficient to make any rraterial difference in the
threatened outbreak and it seems likely that we wv.ll have
very serious da:-iae in the south-central couanties of the
State. The old bugs are so numerous in some cases as
to be killing the heat. In localities here no wheat
is gro'n the eg-s are very al.-nd.ant in oats. This is
true also in some localities w-here both wheat ard oats
occur. No young bugs have been seen -.n the fields as
yet, although eg-_-s are present in large zri.`)ers.

L. Haseman (May 23): The area from Cohl'nbia west and to
the southwest is badly infested with chinch bugs, and unless
wet weothor continues .re are sure to have heavy losses.

H. R. Bryson (Haj 23): Dr. E. G. Kelly reported chinch
bugs very abundant from Miami County south to the 0:la.oma
line and west as far as Suwner County in volunteer oats,
wheat, and barley May 8. Owing to the mild winter, the
extensive burning campaign carried on over this area did
not prove so effective as if the winter -h-d been severe.
Scattered reports from May 1 to 5 show that chinch bugs
were numerous in rye at Vrmillion and were '-illi:-j the
oats in a field at Stark.




South Carolina





C. E. Sanborn (April 28): The chinch bug is moderately

R. W. Harned (May 25): Although no complaints have been
received in regard to damage caused by chinch bugs, a
number of corn plants brouChtto this office from Attala
County, because they were badly infested with larvae of
Diabrotica 12-punctata Fab., had on them so many chinch
bugs, that it is apparent that these insects are unusually
abundant in the field from which the corn plants came.

Co E0,71 C70 ,M (Heliothis obsoleta Fab.)

P. K. Harrison (M!.ay 22): The first larvae this season
were found injuring buds and tassels of corn on the
laboratory grounds at Fairfax.

J. R. Watson (May 21): The corn ear worm is moderately
abundant. It is beginning to be noticeable on tomatoes and
corn, especially to the south.

L. Haseman (May 23): The overwintering pupae of the
corn ear worm show that but a small percentage will probably
produce moths.

J. M. Robinson (M-ay 25): The corn ear worms are moderately
abundant at Auburn.

W. E. Hinds (May 25): The corn ear worms are moderately
abundant in early planted corn and there are some in

Oregon D. C. Mote (April 24): L.. P. Rockvood, on April 20,
together with H. Schoth and the writer, made a survey of
the vetch and Austrian pea fields in the vicinity of
Corvallis. The infestation of the pea aphid was found
to be spotted. In a few fields the infestation was
abundant and there was evidence of dar:-ae to peas and
vetch. In other fields the infestation was scarce and
there was no evidence of damage whatever. A considerable
number of eggs of sprphus flies were present as well as
the fu-ngus Entomo-hthcra aphidis (reported by Mr. Roclkviood).
Only a few coccinellids were observed, but the valley was
experiencing a high wind atnd d-'ist storm which probably
accounted for the absence of the coccilellids. Mr. Schoth
reported both coccinellids and syrphus flies abundant the

in the Lake fruit belt, and on May 25 the first adult was caught
in bait traps in Ulster County. (Abstract J. A. H.)

Weekly News Letter, New Jersey State College of Agriculture
(May): By May 9 approximately 65 per cent of the overwintering
codling moths were in the pupal stage in Gloucester County. A
few adults were observed in this county on May- 16 and by the
23d of the month moths were numerous. (Abstract J. A. H.)

H. N. Worthley (May 20): The first adult codling moth was
captured in a bait pail May 18-19, at State College. (May 27):
About 15 per cent codling moth emergence at State College;
17 per cent at Arendtsville, Adams County.

L. A. Stearns (April 30): Pupation of overwintered larvae
delayed, but 3 per cent had pupated on April 24 at Camden;
abnormally abundant; 75 per cent of overwintered larvae pupated
May 21. First emergence of spring-brood moths May 8.

P. D. Sanders & C. Graham (May 26): The codling moth
emergence is later than in 1930. Last year on May 15 at Hancock
35 per cent of the overwintering moths had emerged and at
Salisbury nearly 40 per cent emerged. On May 15 this year
emergence had hardly begun. There seems to be a much heavier
carry-over than normal, 'bolh inside the packing houses and on
the tree trunks. Peak of emergence on Eastern Shore May 21.
Records not available for this week from western Maryland,
where emergence began on May 11. Records up to May 16 indicate
that that was the peak up to that time.

C. H. Alden (May 20): The codling moth is moderately abundant
at Cornelia, the first-brood eggs hatching from May 17 to 23.

T. H. Parks (May 25): Spring-brood moths began emerging in
Lawrence County May 9; in Cincinnati and Columbus Mayo15, and im
Wooster- May 19, and have not yet commenced to emerge along
Lake Erie. At Columbus only three nights since emergence
commenced have been warm enough for egg laying.
C. C. Compton through W. P. Flint (May 18): Recent examination
of overwintering larvae in orchard cages showed 97 per cent
winter survival as compared with 10 per cent survival under
these same conditions for 1929-30. Pupation started at
Des Pli.ntos May 2, as compared with May- 5 for 1930.

that the earliest emergence occurred in the southern part of
the t'aw- 23d. Moths were emerging in cages from all
parts of the State except the north-central and- northeastern
parts. With'warm weather we expect the peak of first-brood
moths at Columbia by June 1. Emergence of the moths was
delayed by the recent cool spell but moths are now emerging

R. M. Jones (May 20): The first spring-brood moths emerged
on May 4 and egg deposition was recorded on May 17.

Claude Wakeland (May 19): The codling moth began emergence
the first week of May at Parma and Lewiston.

E. J. Newcomer (May 22): The first moths appeared in Ynkima
County April 27 as compared with April 30 in 1930. By the
time of the first cover spray (May 18) about twice as many
moths had appeared in baits as at that time last year, when.
the sane number of baits were used in the same location.
This was due to very warm weather from May 11 to 14.

Monthly News Letter, Los Angeles County Agricultural
Commissioner (April 15): The peak of moth emergence this
spring in the Antelope Valley was reached April 10, which was
three weeks early. Therefore. the eggs laid by. the moth will
be hatching about April 20.

A. I. Bourne (May 23): In his jarring tests Professor WThit-
-.comb found the first beetles on May 15. By the 18th he was
able to collect a considerable number.

Weekly News Letter, New York State College of Agriculture
(May): Adults were obtained by jarring in the lower Hudson
River Valley on May 6. On May 9 they were observed in the
extreme northeastern corner of the State, and by the end of
of the month they were numerous in the Lake fruit valley.
Although considerable fruit scarring has been observed, the
abundance does not appear to be abnormal. (Abstract J.A.H.)

Weekly News Letter, New Jersey State College of Agriculture
(May): Although the plum curculio is being observed quite
generally over the State, it does not appear to be so numerous
as last year. (Abstract J.A.H.)







T. L. Guyton (May): The plum curculio is very abundant.

L. A. Stearns (".ar 21): Emergence from hibernation is
considerably delayed. The first emergence from hibernation
at Camden occurred Aoril 18. The insect arrears to be
much less abundant than it was last yctr.

P. D. Sanders and C. Graham (May 26): The spring e--ere-rnce
is later than in 1930 and on the Eastern Shore is much light-
er. It is felt that both the short reach crop last year and
the hot, dry condition of the soil during the pupation period
were unfavorable for curc-alio development. Jarring records
at Salisbury,1930 showed: May 10, 6.7 curculio per tree and
in 1931 on Mfay 13, only 2.65 per tree. The season is only
about seven days late as judged by the stage of the trees.
Jarring records on curculio indicate heavy invasion of the
orchards about the 16th at Hancockc. Most of the records of
heavy infestations co-nme from jarred apple trees.

C. R. Willey (May 25): The plum curculio is very abundant
at Rich-nond and vicinity. Practically all plum and peach
trees examined were infested, some very badly.

H. G. 7all-er and G. E. Gould (May 25): The plum curculio
is moderately a'.xnTrt at iTorfolk.

C. H. Alden (`!ay 20): The spring brood of the plum curcu-
lio infestation is li ht at Cornelia.

0. I. Sna-on (May 8): This season's infestation at Fort
Valley is the liyhtest 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 infestation 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 whi-n 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 maturity this season left
a poach drop onr. May 7. This is 10 days 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, wer'c infested. On May 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 9 that the curculio infestation in the Georgia
peach belt is the lightest since 1918. V. r' few growers in









Mi ssi s sippi


this locality picked up drops this year on account of the
light infestation, and they were justified in omitting this
usual practice. There has been no pupation to date (May 19),
althou,;h the first larvae entered the soil on May 7. The
continued unseasonably cool weather is retarding development.

That is just ten days later than the first pupation last year
when the pupation was considered unusually late. It is ex-

CERRY IrUIT FILIES (Rhagoletis srn.)


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 wild cherries. I feel
very safe in saying that 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 pennsylvanica.
We have obtained lesser numbers from the other wild cherries
and from some of them we have obtained toi,:f 7.1.i "

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.

CHERRY CASE B3AEPR (Coleo-ohora rruniella Clem.)


C. L. Fluke (May 25): An average of about 25 case bearers

than last month on both ornamentals and citrus. The preda-
cious ladyoird beetle Rodolia cardinalis Muls. 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 and we have
placed many specimens onvarious infestations this past

with the Mexican bean beetle this year than they were last year
at this time,



South Carolina





J4 B. Gill (May i1)t An infestation was first observed on
May 7 on snap beans in gardens within the city of Albany. So
far as my observations go, this is the first year that this
pest occurred in this locality. Evidently this insect entered
here from the north or west and not from the Thomasville
section, where it has been a pest for many.: yaars. The infesta-
tioi'around Thomasville does not spread much.: Present last
year at Americus, which is 37 miles north of Albany, and spread
has been southward. Slight infestation.

C. F. Stahl ('n.y 18): 'In the May issue of the Insect Pest
Survey Bulletin P.123, I note that the celery leaf tier is
reported as "moderately abundant." Of course there may be
different interpretations of the word moderatelyl" but I think
that the statement is misleading if this season is to be com-
pared with previous ones. Certainly the tier has been scarce
and, with the exception of the last few weeks of the crop,
difficult to find.

Rhode Island

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 Codnty. The
cypress bark scale has been found destroying cypress
trees, particularly in hedge rows and -ind-breaks, in the
eastern and southern -arts 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

On MRerch 7, 74 dead larvae -cre taken from *a pilloT- made of seed
cotton, lint, -ool, and mohair. The pillo- originated at Pres.idio, Tex.
and appeared to be three or four years old, *-hich probably accounts for
the fact that all of the speciTens I-ere dead. This is the largest
number of specimens ever tklcen froZ an interception at any of our road

GYPSY MOTH (Porthetria disnar L.)

The scouting has resulted in finding infestation in several tons,
but so far the to'-ns of New Marlboro, Sandisfield, and Sheffield, Mass.,
are more seriously infested than any others in the zone. It is expected
that the '-ork in Piscata-ny and Hillsboro To-nships, Ne,, Jersey, '-ill be
finished about the mTiddle of April. If no further' infestations wv-ere
found, this -ill complete the scouting --orl planned for Ner Jersey this

Tere discovered in the to'-'nshirs of North' Plai-nfield and Warran during
the fiscal year 1928.

B T-TAIL 1MO,7 (yia Dhaeorrhoca Don. )

The bro-n-tail mroth infestation, as indicated by the presence of
the hibernating webs, is heavier than usual in souitheastern Maine and east-

and tons south of AugusI and "est to the TNe- Harpshire tate line, and
in sore cases the infestations are heavy, particularly on apple, pear
and cherry. State officials in Maine have notified the proper authorities
in the cities ag to7-ns as to the proper control methods, and the cutting


and burning of hibernating o-bs is being done in Pore places. Similar
-ork bs being done in Neor H:-krshire by the State and local ruthorities,
as -eol as by POTe individuals. In M1s sach:ctts there is a local roth

The coffee cricket seems to *be follo-ing the same cycle this year
as last: no ne7 oviposition scars have been noted since March. An adult
