INSECT PEST SURVEY BULLETIN


Vol. 11 Tuly 1, 1931 No. 5


OUTSTANDING =ITOMOLOGICAL FEATURES IN THE UNITED STATES FOR JUNE, 1931

me severe armyworm outbreak reported from Texas as far northward as Vir-
gi-a in the last number of the Survey Bulletin became serious during the month
,_ June in the East Central States westward to Iowa. In the East Central
States this insect is doing considerable damage to small grain and corn.

The unusual cutworm prevalence that developed during May progressed
through the early part of June, re-ports of serious damage to a great variety
of crops having been received from Connecticut southward to Virginia and west-
ward to Colorado and Utah. The most serious phase of this cutworm development
is an outbreak of the variegated cutworm which extends from southern Nebraska
across Kansas and into Oklahoma and Ar':;:as.

During June grasshoppers developed to such an extent as to require con-
trol measures in northwestern Minnesota, throughout the two Dakotas, southward
through Nebraska to north central Texas, and westward into the Great Basin re-
gion. There is a local outbreak in Klamath and Lake Counties, Oregon, where
25,000 pounds of poisoned bran mash are being distributed daily for their con-
trol.

Wireworms have been reported as doing rather severe damage to corn in Ver-
mont and Pennsylvania and to a variety of crops from New York southward to
Maryland and westward to Iowa and Nebraska. The wireworm Heteroderes lauren-
tii Guer. more seriously dn.Tmu'u-d the commercial Irish potato crop of Alabama
than it has in any year since its discovery in that State.

The Hessian fly is apparently decidedly on the increase in the East Cen-
tral States, with scattered serious infestations in Nebraska and. Kansas. Ra-
ther heavy infestations of spring wheat by this insect are reported from the
Willamette Valley of Oregon.

A rather unusual infestation of wheat by the tenebrionid Blapstinus gre-
.galis Casey in the region north of Qreat Falls in Montana occurred during the
month. In the infested fields as many as 100 beetles to the square yard have
been observed.

During the last week in June recently hatched chinch bugs were observed
in the heavily infested area extending from western Ohio to southeastern Xan-
sas. The outbreak this year se-ems to be more severe than has been recorded
for several. years.

The corn ear worm became seriously destructive in the Gulf region and
the lower Mississippi Valley during the early part of the month and was
first observed in Nebraska about June 10 and in Maryland June 15,

More damage has been occasioned to corn by sod webworms in the East
Central States than has occurred in a number of years, very serious damage
being reported from Ohio westward to Iowa.

The velvetbean caterpillar appearedin the Everglades of Florida on
June 10. This is about two weeks earlier than in 1930.

During the early part of June the rosy apple aphid developed to serious
proportions in southern New England and in the Middle Atlantic and. ast
Central States extending southward to Arkansas. Very heavy infestations
by this insect are also reported from the Pacific Northwest.

First side-worm injury by the codling moth was reported from Massachu-
setts about June 16. By the middle of the month eggs were hatching in the
Hudson River Valley of New York and by the third week of the month they
were hatching in numbers in western New York. Side-worm injury had start-
ed in southern New Jersey by June 9. From the Hudson River Valley south-
ward to Georgia the codling moth seems to be unusually abundant. Very
heavy infestations are also reported from the greater part of the East
Central States westward to Nebraska and Kansas. In the Pacific Northwest
the codling moth situation is more serious than it has been for several
years.

Apple leafhoppers are doing considerable damage in the Northeastern
and Middle Atlantic States southward to North Carolina.

The oriental fruit moth situation on the whole seems to be much less
serious than at this tinge last year.

Although the light infestation of the plum curculio reported in the
last number of the Survey Bulletin prevailed over the South Atlantic
States, infestation by this insect developed to rather serious proportions
in the Hudson River Valley and Connecticut. The first beetle of this
year's generation to be observed in a pupal cell was seen at Fort Valley, Ga.,
on June 1. The first transformation reported last year was on May 23, which
itself was considered late.

Considerable damage was done in southern Georgia to pecans by the pecan
leaf case bearer, while in Florida the nut case bearer destroyed over 75 per
cent of the crop about Jacksonville. In the vicinity of Albany, Ga., the
nut case bearer infestation is extremely light.

The hickory shuck worm on pecan is occasioning considerable alarm in
parts of Georgia and Mississippi.

The Mexican fruit worm was found infesting locally grown fruit at
Matamoros, Mexico, and in a grove near Mission, Texas.

The seed corn na& ot was rather dost m-c"ive in 173 'York and the East
Central States south*'a7rd to Kentucky and c-strard to Tebr't,-a.

The cabbage mag~ot is occurring in outbreak nuribers in Connecticut,
1oe- York, and New Jersey, ,7ith serious da-:ace also reported from Irni.3.na,
Kentucky, and Wisconsin. In Connecticut one grovcr estimated his loss at
bet'.7een 2,000 and 3,000 plants, while plants in unscreen.ed beds in :Tor- York
were dria.-ed from 15 to 60 per cent.

The Colorado potato beetle continued to be unusually abundant in the
Middle Atlantic States westward to Illinois, and an unusual outbreak of
this insect was reported from north-Lestern Iowa.

The potato aphid is much more abun-ant on potatoes and tomatoes on the
eastern shore of :,aryland and Virginia than usual. This insect is also
reported as being very abundant in Indicana and Ohio.

The Mexican bean beetle is cauxirn, serious damage in HErtford County,
Conn., and became so nm-ierous in ports of ev" J.rsy, that the supply of
insecticides for their control w.s eo! r-Lstcd.

The asparrmgus beetle nas very troilblesome from Connecticut westward
to Iowa, complete devastation ta-in place at may points. This insect
is also accr.i:'.? a serious pest in Col'rado and California.

Throughout practically the entire country, from WTcw T_ and to Florida
and westward to Iowa a:d "ltbrask., the stripe. ctcu.ber bctle is being, re-
ported as unusually dostractive.

From central Ohio *;vest"-rrd to Wisconsin the poe. aIphid is so abundant
that the p..- crop is seriously threatened.

The potato tuber worm wne fow'ad attac:lin.- tobacco ot several places in
Kent:ucky during. the third -eeh in June. Tis is v-id to be the first rccord
of the occurrence of this insect in t-. Stat.

A very heavy emergence of 3rlod V of the moiodic.J cicada is reported
from the upper end of Long Island. The ocrur-c'.-.c Lf Br-)'d 7 in T'..' York
State was first definitely established Iy 7. T. ,.vis in 114, althouh
there are a few old records of this broid's appering there in 1897.

Canker worns have defolia.ted lari'c areas cf forest l-ids in the -R'd River
Valley of North Dakota and are much norc nwrrous tlan usual in parts of
Minnesota, Iowa, i'cbraska, anld 'Ki.', .

The elm loeaf beetle is prevalent in southern 1eov' M-land and is ap"earinj
in large nuribers in Rh.de Isl'nd.

We wish to call the attention of our rca-rers to a r.ista2k-. in pngination
in the last number of the S Brvcy Bulletin. Pawo 237 should be 2-6_; p-nc 238

OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA FOR JULTE, 1931.

Damage brby the pale western cutworm, which was present in outbreak
form over much of Alberta and Saskatchewan, is drawing to a close. In
most of the infested areas the majority of the cutworms were nature, or
nearly so, towards the end of Ju)e, and reseeding could be carried on
with little fear of loss. By the time the crops have been reseeded the
cutworm menace will be over for this season, and with sufficient moisture
there will be little or no delay in the growth of the crop. The red-backed
cutwormr is widespread in the northern and central areas of Manitoba, damag-
ing grain crops, and local reports hLave been received of the prevalence of
this species in Alberta. Cutwoorms of various species are also abundant
and injurious to field and garden crops in sections of eastern Canada, and
in parts of British Columbia.

Grasshoppers are threatening destruction to alfalfa and other crops
in the Fraser Valley, British Colurnbia,between Lytton and Lillooet. Local
outbreaks have developed in the western half of south-central Saskatchewan,
and localized da:ge to grass and grain crops is reported from Manitoba.
The moderate grasshopper outbreak of 1930 continues in southern Quebec.

Wireworms are proving injurious to a serious extent on a variety of
crops throughout southwestern Ontario. In Saskatchewan it is expected that
dam-age by these insedts will be the heaviest on record.

Sod webworm larvae are proving more abundant and destructive in sections
of southern Ontario, where they are attacking timothy and June grass sod,
than has previously been recorded.

An exceptionally heavy flight of June beetles developed over an area
of more than 4,000 square miles in southern Qaebec. The flight reached its
maxinLun towards the end of ay. The beetles caused much defoliation of
deciduous trees and shrubs.

Adults of the Colorado potato beetle appeared in greater numbers in
Manitoba than had been anticipated, in view of the lack of snow during the
past winter. Reports indicate that this species is unusually abundant in
southwestern Ontario, and is likely to be severe in southern Quebec.

Large flights of adults of the booeet webwom have occurred in southern
Saskatchewan and in sections of Manitoba, indicating a possible outbreaks
of the larvae of this species on weeds and garden plants.

The San Jose scale has been found on apple trees in the Indian reser-
vation at Night Hawk on the international boundary near Keromeos, British
Columbia. The San Jose scale does not seem to flourish in British Columbia.

It is anticipated tha?.t the com.rion red spider will prove even more
injurious to raspberries in the Niagara peninsula, Ontario, than in 1930.
This species is locally severe in southern .Manitob,?., affecting spruce and
small fruits. Spider mites are epidemic on coniferous trees in Saskatchewan.

M. P. Zappe (June 20): Cutworms were causing severe injury
to young apple trees, budded last year, at Durham Center.
Early in the spring they ate out the buds and later fed on
new leaves. They were very abundant on a variety of plants
in New Haven County.

A. I. Bourne (June 26): In late May and early June there
was reported to us a rather severe infestation of cutworms
attacking strawberry beds in the Cape section in Barnstable
County. Prof. Whitcomb reports that it was probably the
darksided cutworm, 'Euxoa messoria Harr.' although this has
not been definitely determined. He reported that practically
all of the acreage of strawberries in the region around
Falmouth showed infestation and in the worst infested fields
from one-fourth to one-half the leaf area of the plant had
already been eaten by late May. It was not at all difficult
to find from 4 to 10G cutworms hidden under the mulch around
one plant. He reports a serious outbreak of climbing cut-
worms in apple orchards in Essex County where the spotted
cutworm, Agrotis (-nigrur, was seriously damaging buds and
foliage of apple trees about the middle of May.

N. Y. State Coll. of Agr., Weekly News Letter (June): Cut-
worms wore quite generally severe over western New York, par-
ticularly to tomatoes, and in one planting in Chautauqua
County 68 per cent of the plants were cut off in three days.
(Abstract, J.A.H.)

NIT. J. State Coll. of Agr., Weekly News Letter (June 2):
Cutworms are abundant and doing considerable damage to newly
sot tomato plants in Burlington County.

J. N. Knull (June 11): Cutworms have been very abundant
in small gardens throughout the Mont Alto State Forest.

C. A. Thomas (June 19):.. Cutworms were abundant and de-
structive during Mayr and June in southern Pennsylvania, eat-
ing off cabbage, tomato, bean, and numerous other small plants.

E. N. Cory (June 22): Cutworms are very abundant in Anne
Arundel County.

17. S. Abbott (May 25): One report of very heavy damage to
strawberry plants by cutworms has been received from Silver
Spring.

G. E. Gould (June 24): Cutworms of several different species
have been reported causing damage to different crops in Norfolk.

One species has been cormion in cucumber fields, cutting off
the young plants, while another species has been found feodi--:
in the cabbage heads. Dmiaaze to honre vegetable and flower
gardens is common.
t
E. W. M'endenhall (June 18): The climbing cutworm iA-roti!
unicolor Walk.,' is very bad on %rden crops in lake- County.

J. J. Davis (June 24): Cutworms were predominating pests.
During lay they were primarily pcsts of corn but from May 25
to June 10 (especially the last few days in IMay and the first
few in June) they were primarily garden pests. All kinds of
garden crops were attacked, tomato being the most commonly
damaged. Other garden crops attacked included melons, potato,
and cabbage.

W. P. Flint (Jane 20): :Moro reports of cutworms have been
received than for many years. The principal species have
been the clay-backed (?Oltia gladiaria Morr.,) and 9ristly
(Polia renigera Steph.) with a very few black cutworms
(Arotis ypsilon Rott.) now appearing.

W. A. Price (June 25): Cutworms -have been very abundant
generally over the .tate, but now are disappearing.

R. Hutson (June 20): Cutworms are very abundant in orchards,
and moths are appearing.

C. H. Koonz (June 24): Cutworms are very abundan-t and have
destroyed much corn.

A. G. iaggles and assistants (June): Cutworms, though very
destructive earlier in the month, are -encrally of minor im-
portance at the present tine. (Abstract, J.A.H.)

M. H. Swr2c (!:iy 15 Juno 15): An aftermath of the plenitude
of the army cutworm (Cioriz?.:--rotis auxiliaris Grote) in April
was the heavy flight of moths of this species, much inquired
about and complained of during the first half of June. All
parts of the State were more or less involved in these flights,
but more especially the western and central parts. (June 8 -
13): During the second week in Juno, from the 8th to the 13th,
there was a sharp outbreak of the variegated cut'7orm (I.cophotia
margaritosa saucia Hbn.) in southern and eastern N5obraska. The
outbreak centered in severity in the southern tier of counties
from Furnan County east to GaCoe and Lancaster Counties, and
especially in southern Franklin County around Naponee, FrankThlin,
and Rivt.rton. Many fields of alfalfa, sweet clover, and potatoes
were involved, and some of them were completel.- stripped of
leaves. There :'!as trouble with this climbing cutworm durin-
the same period in northeastern eobraska, centering about Dakota
County.





-243-


D. B. Whelan (May 15 Jiune 15): Daring the second week in
June a few yellow-striped armrayworms (Prodenia ornithogalli
Guen.) were found in the sweet clover fields in Lincoln that
were being injured by the variegated cutworm.

.Iowa C. J. Drake (June 27): Several species of cutworms occur
in large numbers throughout the State. Considerable damage
has been done to corn, alfalfa, clover, garden, and truck-
crops. In some alfalfa fields the cutworms are extremely
abundant, and farmers report that as soon as the hay is cut
the worms start feeding on the leaves. In several instances
the worms have been so abundant that they have been picked
up by the hay loader and mixed with the hay to such an extent
that the hay cannot be put into the barn. Several fields of
corn have been badly injured or totally destroyed by cutworms.

C. N. Ainslie (June 11): Cutworms of several species are
exceedingly numerous around Sioux City. All gardens are suf-
fering and large potato growths are being cut off. A flight
of the moths is attracting attention and exciting much comment.
When their day hiding places are disturbed they fly in large
numbers. (June 15): Damage from cutworms appears to be on the
increase around Sioux City as the season advances. Potatoes
are being badly injured and, in at least one field, corn a
foot high is being cut off below the ground level and is being
replanted in some damaged fields. (June 24): These specimens
were determined by Dr. Schaus as Chorizarotis auxiliaris
Grote and C.rc~rtis Grote.

Kansas H. R. Bryson (June 22): Cutworms are very abundant and
general in distribution as far west as Dodge City. The
variegated cutworm (Lrcophotia margaritosa saucia Hbn.) has
been very abundant this spring, being of almost general dis-
tribution over the entire State. The greater portion of the
injury resulting from the ravages of this pest has been re-
ported from alfalfa fields or fields adjacent to alfalfa fields.
The larvae killed or seriously retarded the second crop of
alfalfa, causing some fields to appear brown. In many instances
the larvae migrated from the alfalfa fields to nearby corn
fields, vegetable gardens, or orchards, where they continued
their destruction. At Manhattan in the college orchard the
moths laid eggs on the vetch plants used as a cover crop. The
larvae soon devastated the vetch and migrated to the grapevines,
where they began to defoliate the plants and attack the young
bunches. The young peach fruit was injured considerably. The
writer observed five larvae in one peach during the day. The
larvae in the trees continued to feed during the day. The
greater part of the injury to truck gardens was done at night.
On a recent trip to Hay and Colby, R. H. Painter four varie-
gated cutworms injuring sweet clover but not uncut alfalfa
near by. At Colby they had migrated from alfalfa to elm trees
and other plants.

C. E. Sanborn (May 21): The rarieeI7ted cut-7orm is doir: ser-
ious donarc to alfalfa at Alva,, Oihia City, Pauls Valley,
1li.s':ogee, Tuolsa, and StillWAter.

D. Iely (June 23): There has been an outbree-k of unusual
severity of the varieatc4 cutworm, du&'rin the .latter part of
May and tic early "-'rt of June. This outbreak occurred along
the Mis.issippi and Arllanzas Rivers, from the northwestern
corner of the State to the east central part. I'ost of the
rinfcstmtions were centered around alfalfa fields from which
the worms moved to destroy adjoining crops of corn-and cotton.

StE.te Plant Board, Press Release (Jun,: 1): In one case in
Washington County 160 acrcs of spring alfalfa was destrorci
by the varie-ated cutworm.

C. P. Gillette (Jnr.o 23): The red-backed cutw.orm ( iu-a
ochro...,ter G'.en.) is "'cr" abu,=,ant in southwestern Colorado.
Oiriza.-,':is sp. and. `-he 1'a e lrcsern c-.t'-jrm (Porocagrotis

G. F. nowlton (June 6): Cutworms are seriously damnaginj
many fields of sugar bceets in the area west of Sprinqville.
Tv'enty acres in one field Ihad to be replanted because of this
damage, and large areas in other fields are bare at the present
time. Injury to beets in the Sevier Valley has been reported.
Four acres of beets rere destroyed west of Provo. (June 10):
Cutworms have been causi.-1i dna-ca to suar beets in several
fields in Boxeldor, Cache, and Utahi Counties.

L. P. Rocl.-ood (June I): Moths of A. -IL',_on Rott. are some-
.-'at more numerous than in 1930 in b-it tra.!, on land over-
flowed until earl May. :.'o damage is boin.T done.

statement: "Last week just as my wheat was in bloom on some
pasture land the worms seemed to start in the same place as
they did last fall and in two days had completely destroyed
all the blades of wheat as well as the stand of grass, which
was about 6 inches high. There are three larger farms a few
miles away entirely demolished already." At least 95 per
cent of the specimens were infested with parasitic eggs which
I take to be tachinid flies.

C. H. Brannon (June 10): Serious damage by armyworms has
occurred in Halifax, Iredell, New Hanover, and Currituck Counties.

T. H. Parks (June 24): Armyworms appeared in Franklin County
June 20 and in the past four days have been stripping several
rye fields of their foliage and are feeding in some wheat
fields. They have already begun to migrate to corn and have
destroyed about 10 acres of corn in 3 days on a farm 4 miles
east of Columbus. The infestation in Franklin County has been
reported only in the southern half of the county and usually
starts in rye fields. Reports also come from Pickaway, Fair-
field, Clinton, and Madison Counties.

J. J. Davis (June 3-9): The common arryyworm was abundant
and destructive to barley, wheat, oats, and corn in southern
Indiana. Definite reports show general abundance in Posey,
Gibson, Warrick, Harrison, and Monroe Counties.

W. P. Flint (June 20); Armyworm outbreaks have occurred
throughout the southern part of the State, but are not occurr-
ing in the central area. In most cases the outbreaks have
been of only moderate intensity. In a few instances very large
numbers of worms have been present in the infested fields.

VWT. A. Price (June 25): The armyworm outbreak covered prac-
tically all the State except the eastern mountainous section,
attacking corn and bluegrass. Its first appearance was noted
at Hopkinsville on May 23; Lexington, June 2, and Maysville,
June 6. They began pupating at Lexington in numbers on June 16.

C. J. Drake (June 17): The first armywonms were reported in
Iowa yesterday, June 16. The worms were noted in large numbers
in a 60-acre field of corn about 20 miles south of Des Moines
and at Logan, Iowa. At Logan the worms completely destroyed
6 acres of corn before they were observed. During the latter
part of May and the fore part of June armyworm moths were noted
in large numbers flying around lights. (June 27): Outbreaks
are taking place in Cerro Gordo, Crawford, Logan and Monona
Counties. At Clear Lake the armyworrs have totally destroyed
a 20-acre field of rye.

C. N. Ainslie (June 18): An outbreak of the armyworm is re-
ported from near Salix, 25 miles south of Sioux City. Corn
appears to have suffered the worst from the "attack.

L. Hase.man (June 22): In several. counties an outbreak of
armyworms appeared. The "'orrr.s were practically mature before
any-of the farmers reported them. rest central Missouri has
many heavily infested clover and alfalfa fields. The worms
are .practically all of the pale variety this vear. A few
moths have alread;r appeared (June 22) and practically all of
the worms are .almost ful: r...cd7o miration occurred, owing to
the excessive supply of vegetation whore they hatched.

M. H. SW.iej: (May 15 June 15): The month of May was cool
and there were larje flights of the moths of the armyworm
beginning about May 22. The first report of 'such an outbreak
came from Thayer County on June 16 where the" armyworms were
damaging a rye field. This is a very early date for armyworm
damage in Nebraska. For comparison armywo.rms of the first
brood were reported as doing dnaj.Te in 1921 on June 20, in
1919 and 1927 on June 22, in 1912 on June 23, and in 1930 on
June 28, and still later in other'years.

A. C. organ, J. U. Gilmore, and J. Mila" (June 22): The
true armyworm was the cause of considerable damage in Christian
County, Ky., and also in Mohtgomery County, Tenh. Grain fields
in many instances were completely defoliated and often half
the immature heads were cut off.

D. Isely (June 23): Local injury by Cirphis unip-ncta, was
associated with the variegated cutworm outbreak in the eastern
part of the State.

St. r.lit Bd., Press Release (June 1): In 'Smunflower County,
on one plantation of 200 acres, all oats were badly damaged
by a worm which was thought to be the true armywor., of the
NTorthern States. Prof. Earned states that this is the first
record of this insect assuming the arm-, habit and causing so
much da-iage in Mississippi. The worms were reported as numerous
as one to each square inch. The damage occurred so suddenly
that control heasuires were not used in time to do much good.
Parasitic flies w.ere observed attc-,in-; the worms in large
numbers, and it is believed that no daziage will occur from a

PAINITED LADY (Vanossa cardui L.)

J. J. Davis (June 7,41',12): The thistle caterpillar, V. car-
dui, was reported noticeably abundant on Canada thistle at Lo-
gansport, June 7, Fowler, June 11, and Anderson, June 12,

A. G. Ruggles and assistants (June): This insect is occurring
in rather unusual numbers and destroying Canada thistle over a
wide area in southwestern Minnesota. (Abstract, J.A.H.)

C. J. Drake (June 27): The thistle butterfly is extremely
abundant and occurs in almost every county in the State. Some
farmers report large patches of Canadian thistle practically
destroyed by the feeding of these caterpillars. The Canadian
thistle seams to be more readily attacked than the other
species. It has not been reported as doing any damage to
cultivated plants.

GRASSHOPPERS (Acrididae)

H. S. Adair (June 24): Grasshoppers (Melanoplus femrur-rubrum
and other species) have been rather abundant in some places
around Albany since the middle of May. They have recently been
reported injuring peaches in an orchard near Albany and have
been observed. feeding some on pecan leaves in orchards where
they are abundant and 'the grass sand weeds have died because
of dry weather leavin- the pecan as the only available green food.

T. H. Parks (June 2.3): Grasshoppers are moderately abundant.
They are just hatching in pasture fields and will be serious in
some localities.

W. A. Price (June 25): Grasshoppers are very abundant on
tobacco and alfalfa.

A. G. Ruggles and assistants (June): Grasshoppers are appear-
ing in rather large numbers in the extreme northwestern part of
the State and in the counties i,mediately north and west of Min-
:..olis and St. Paul. (Abstract, J.A.H.)

J. A. Munro (June 17): According to reports I have received
on the grasshopper situation in various parts of the State, I
should judge that it is the only insect problem to cause real
alarm. I have already had several reports from farmers and
county agents in2 the eastern counties that the young hoppers
have already taken garden stuff, some small grains, and alfalfa.
Directions have beer. sent in response, to aid in control. I
understand that hoppers are very abundant at Minot, Ward County,
and that the county agent there has boon directing control`
measures over a fairly large territory.

X. C. Sevorin, (June 10): Grasso -c.rcrc are reported as already
severe on small grain in C-.rles Mix, Brule, Tripp, Lynan, Mel-
lettoe, Jones, Jacs:on, HuThes, Stanley, and aakon Counties.
Some trouble also in Perkins, Corson, Clay, and Ben Hor:me Counties.

L. Easuean (June'22): Waste places, metdows, and pastures
are literally alive with grassbopper nm.phs recently hatched,
mostly apparently of the red-leg-ed species (M. femur-rubrun
DeG.). We are certain to have a real outbreak where steps are
not taken to destroy the nymphs.

M. H. S'enkr (aty 15 June 15): The outstanding entomological
develo!cent in :!Tbraska during the period here covered has been
the outbreak of grasshoppers, mainly of the two-striped crass-
hopper (Melanoplus bivittatus Say) in Boyd and. urro'di. coun-
ties in the northeastern part of the State, this 'being a south-
eastward extension into YTebraska of a general outbreak covering:
more th,%n a tho-.-s:'An square miles in southeastern South Dakota.
The first reports of da-:a::e in Xebr-sha came fror eastern Boyd
County during the third week in May, when quarter-grown grass-
hoppers were found in abundance attacking alfalfa and other
crops, with the pests still h.atching in rnumbers from the pastures,
.hay :mcidowvs, and stubble fields. This outbreak extended during
early June to include all of Knox, n-orthern Holt and Rock, all
of Boyd, and the eastern part of Kcy'paLha Counties. Three other
areas of grasshliopper trouble that Ihave developed in Nebraska
during the last few days of Meay and the first half of June
include (1) a sandhill infestation in the valley alfalfa and
oat fields from Greeley County -vest to Grant and Arthur Counties
and less intensely to Morrill County; (2) a southwestern in-
festation from Perkins County south to Dundy County and east to
?urnas County, in which area there is at this tine promise of
serious trouble in nr-icrous localities during June and early
July;: and (3) a similar area centering in Adains and Clay Counties,
were the grasshopers started hatching, in abu-ndance in early
June and threaten da%-.ge. The dnxage in these t'xree areas does
not 'promise to be as hoavy as in the northeastern area. The en-
ti'o southeastern part of Neobr-izIka, from Clay County east to
the Missouri River, and from i rnaha Countty to Vashir :ton County,
ias :ving an unusually large .hatch of rasshoppers, with some
d*ia 7c already evident in alfalfa fields and in vegetable and
flower ard-ens.

H. R. Br:'son (June 17): Grass'hoppers are reported doing some
i-r.age at Courtlc.d.

C. F. Stiles (Juno 22): Various species of grasshoppers are
very ,bx.'d."t in southern and southwestern Oklahoma.

F. L. lheor-.s (June 23): C.r'..o.'cr' are Toderately abundant
in west central, northern, and northwestern Texas (57 counties).

C. P. Gillette (June 23): Grasshoppers (Melanoplus sp.)
are more abunidant than they have been for many years.

G. G. Schweis (June 26): Gras shoppers are very abundant in
western Nevada.

C. D. Lebert (June 24): Several species of grasshoppers are
very numerous in the Valley. The most prevalent in June are
I1. differentialis Thos., M. atlanis Riley, M. flavidus Scudd.,
and Trimerotropis spp. All of the above were noted on the
alfalfa, and grassy lands of fence rows. Some damage is reported
to young citrus seedlings.

C. L. Corkins (June 23): Grasshoppers are ,very abundant and
apparently all of central and northeastern Wyomin. is affected.
'Sheridan, Converse, Nl-tona, Washakie, and Park Counties are
reporting damage.

G. F. Knowlton (June 6): Grasshoppers are still damaging
strawberries in parts of Utah County, and are beginning to
cause slight ,injury to beets. At the present time they are
threatening deamnage to alfalfa, grain, and beets in the Elberta
and Genola areas. (June 16): Grasshoppers are stripping the
leaves from wheat and attacking the heads in the area west of
Garland where wheat fields adjoin range land. Ml. atlanis Riley
and tilocara elliotti Thos. are the most abundant species found
and about 2 per cent of these have become adult. A few adults
of M. bivittatus Say were also taden. Part of one alfalfa
field southwest of Penrose has been stripped of leaves by
grasshoppers, M. atlanis being the most abundant form with
about 5 per cent of the specimens taken having become adults.
Barley in this area was being dsnaaged by M. bivittatus and M.
atlanis.

Oreg. Agr. Coll., Insect Pest Report (May): C. A. Henderson
reports that grasshoppers started hatching in the Klamath
district May 1, and the hatching season is now in full swing.
Territory involved includes Chewaucan Valley, Sycan Valley,
Upper Klamath Marsh, Spragu-e River, Fort Klamath, head of
Williamson Modoc Point, 1larath Agencyr, and Lower Klamath Lake,
and there are a few hoppers in Tule Lake. Klamath and Lake
Counties jointly are poisoning over a half million acres, using
about 25,000 pounds poisoned bran mash daily.

L. P. Rockwood (May 31): First-stage larvae of Melanoplus
sp., probably fomu-ru-brum, appeared May 31. It is too early
to predict abnd-ance.

one field v:hcre the stand was uneven, uiinder,'rournd stalks '"ers
cxamincd and wee found to be chewed, probably by vireworms,
as the field had been in sod several yer-rs and was not fall-
plowed in C.;,-a7J County. The wheat wircworm (Ari~te mncus
Say) was seriously infesting tomato plantin-s in western NTewv
York. In one field in Grrnesee County 20 per cent of the plants
were killed by thi, i.secrt. (Abstract, J.A.H.)

C. A. T?.-nips (June 23): Probably because of tl'-c cool weather
in lay ri-rc-iorms have caused considcrr.ble injury in Pennsylvania
so far this sea";n. A survey in rmid-MLay to mid-June showed
that A. mancus was destructive to corn and oats in Alleheny,
Mercer, Crawford, and Erie Counties. The above and Mclanotus
colTf.nis Gyll. and Pheletes azonus S'.y are the three principal
economic voirro'roms of this State. The drought of last season
was evidently no deur'e.it to this year's wire.ornom activity.

A WTIRHJOBi (lieteroderes laurentii Guer.)

K. L. Cockerham (:.>- 30): There !as been injury by this
wireworm to Irish pottoes in Baldwin County, Alabama. Injury
to the commercial crops this spring is far greater than at any
time since this species was discovered in southern Alabama.
Many individual crops show injury to more than 50 per cent of
the potatoes h:.rvested, and reports, by the government inspec-
tors of the Bureau of Markets, show that damage to all cars
inspected by them at some of the shipping platforms for the
last week has averaged. 25 per cent or more. Early every car
shipped since Iay 15 has shown some "-w6rm injury." (June 4):
On this date Irish potatoes were found severely damaged by
wirewrorns. The species responsible for the great bulk of the
injury in St. Elmo, Mobile County, is H. laurentii.

0. T. Deen (June 8): On a short scouting trip during the
first week of June tie following localities and counties were
found as new points of infestation for the introduced wireworm

CEREAL ANDITORAGE-CROP INSECTS -

WHEAT

HESSIAN FLY (Phytophaga destructor Say)

T. H. Parks (June 24): The Hessian fly is on the increase
after two years of comparative absence. A field of early-
sown wheat near Columbus was found today to be seriously in-
fested, with many broken straws. The annual wheat insect
survey has not yet commenced but it is apparent that this in-
sect has increased greatly since last year.

J. H. Bigger (June 15): The Hessian Fly is very abundant
in western Illinois. Much wheat was going down in some coun-
ties, May 21.

W. A. Price (June 25): The Hessian fly is moderately abund-
ant.

H. E. Jaques (June): The Hessian fly is very abundant in
Pottawattamice County.

M. H. Swerk (June 22): The Hessian fly 'is 'moderately abund-
ant in southeastern Nebraska, though there has been no com-
mercial damage as yet.

H. R. Bryson (June 22): Dr. R. H. Painter reports a light
infestation on spring wheat at" Manhattan extending west to
Salina with a heavier infestation near Lindsborg and Lyons.
Some fields were found in a recent trip to western Kansas
near Hays, Colby, and Dresden, in which 100 per cent of the
plants were infested.

L. Haseman (June 22): The spring brood of larvae has caused
comparatively little damage to wheat over most of the State,
but the fields are generally infested, and with favorable con-
ditions we may have a heavy outbreak this fall.

M. M. Reeher (June 1): Some fields of spring wheat in Wash-
ington and YTmhill Counties show rather heavy infestations.
Hot dry weather has prevented the emergence of the second gen-
eration of flies to date.

ENGLISH GBAIN APHID (Macrosiphum granarium Kby.)

J. J. Davis (June 24): The wheat aphid (M. granarium) was
abundant and apparently destructive to wheat heads at Lyons,
June 8. They were later reported abundant on wheat heads at
Marion, June 20, and Rensselaer, June 22.

JHIAT JOINT 70ORT (Harmolita tritici Fitch)

Orcgon Oreg. A.-r. Coll., L-,.scct Pest Report (May): T. R. Chamber-
lin repoorts that approximately 5 -ocr cent of the 'heat join
worm were out of the stubble by 7,' 6 in the Molalla district.
The parasite jrIt:m. parva Fhillips had barely begun issuance.
Joint wTorms and E. Darva were all out on May 26, adult joint
worms being rather scarce and :. parva the more numerous. In
late May the parasite Ditropinotus aureoviridis Cwvfd. vwas still
in the larval state. The weather seems to have been favorable
for a heavy infestation of w-heat.

PU-'I!7S FAL5E 7I=r70FRI (Eleodes oin.cr Say)

South Darlta H. C. Scvcrin (June 10): Plains false wirew:orms are re-
ported as causing severe damage to small grain and flax in
Stanley and Haakon Counties.

Texas F. L. Thomas (June 23): False vwircvorms arc very abundant
at Plainviewv, also in Floyd, Hal, Lamb, and Sisher Counties.

SA TE,1S3RI0:'ID 3:BEETLE (Blanstinus -:rc.alis Casey)

Montana G. A. i/iail (June 5): I would like to report that the tone-
brionid B. rC^-.li. is this spring doing considerable damage
to v:heat in central and vcstern Montana. In certain sections
they are so numerous that under each clod of earth in a field
there will be 15 to 20 beetles, and a conservative average in
arc;s where they are doing the most danm-;e would be 100 to
the square yard. Both s-nring rand winter heats are being at-
tacked and the insect is also recorded as attacking sugar
beets. The beetle seems to be vwidespread but tnc localities
where the most severe injury is reported are north of Great
Falls.

A LE-F;U.PF:rp (Deltoccrhalus confiAuratus Uh.I.)

Nebraska M. H. Swenk (May 15 June 15): A fe. wheat fields in Scotts
Bluff County were so heavily infested with the Icafhopper D.
configuratus during the first week in June that the plants
were killed out to a considerable extent.

SAY'S PLAITP BUG (Chlorochroa sayi Stal)

Utah G. F. I'nowlton (June 22): A serious outbreak of Say's
plant bug is occurring on Bountiful Brnch. The adult bugs
are extrcuely abundant, and attacking the heads of wheat,
one to four hugs boi'.: present on.nearly every head in the
fields examined.

APPLE GRAIN APHID (Rhopalosiphum -orunifoliae Fitch)

R. H. Pettit (June 26): An epidemic is raging in the grain
fields of Michigan. Reports are being received daily that
the heads of wheat are packed full of lice. An examination
of all specimens sent in thus far indicates the presence of
the northern grain aphid.


CORN

CHINTCH BUG (Blissus leucooterus Say)


Ohio


Illinois











Missouri












Kansas



Arkansas


T. H. Parks (June 20): Young bugs are now appearing on
wheat and foxtail grass in western Ohio. cExaminations of
wheat and barley fields indicate that there will be many of
these bugs in July, and county agents are preparing to as-
sist farmers to protect their corn.

W. P. Flint (June 20): The moderately heavy rains occur-
ring during the first part of June were not sufficiently fre-
quent to cause any great reduction in the infestation. Young
bugs are now hatching in very large numbers and the infesta-
tion will apparently be heavy enough to cause slight to se-
vere damage over 'the southcentral part of the State from Ful-
ton and Champaign Counties southward to Randolph and Perry
Counties. The insect is numerous enough to cause heavy loss-
es in Christian, Montgomery, Bond, Clinton, and WJashington
Counties.

L. Hasem-an (June 22): Chinch bugs are more abundant through
central Missouri from the Kansas line to the Illinois line
than they have been in many years. Unusually favorable weath-
er for the development of wheat, coupled with the late migra-
tion of the bugs, has apparently prevented severe damage to
wheat. On June 22, while the adults are still mating and ovi-
positing, early hatched nymphs are fairly covering the base
of corn, oats, and wheat plants, where the fields are badly
infested. Many cornfields are infested with the old bugs
owing to the late flight and by the first of July we are ex-
pecting the migration of the young bugs from wheat to corn
and our farmers are prepared to fight them with barriers.

H. R. Bryson (June 22): Chinch bugs are very abundant.
Corres-oondence indicates that this insect is a menace in
southeast ern Kansas.

D. Isely (June 23): Local injury by chinch bugs to corn
has been re-ported from a number of counties in the eastern
part of the State.

St. PI. Bd., Press Release (June 8): Several cDolaints
of chinch bugs have been received from various sections of
Mississippi. They are probably -norc abundant this season
than usual, according to Prof. R. W7. Harned, on account of
the prolonged drought of last summer which was very favor-
able for them-n. They cause the greatest da-nmae in this State
to corn and oats, generally fading in large numbers around
the roots, inside the leaf blades, and on other parts of
the plants. Serious injury to corn usually occurs when this
crop is adjacent to oats.


"7HITE-LI W SPHITX (Celerio lineata Fab.)


Iowa

C. NIT. Ainslie (June 8): A complaint that corn on low land
was being eaten by these worms was investigated and it was
found that numerous larvae had wandered away frorrm dock (Ru-
mex sp.) and that corn had beeoon injured but not seriously.
The larvae were of all sizes and appeared to relish the corn
diet, a most unusual food for the species.

C. P. Gillette (June 26): This insect is very abundant,
mostly on weeds at Greeley and Collins area.

D. B. Thelan (May 15 June 15): The first generation be-
gan hatching about June 10. Adults, e-fs, an.7 newly-hatched
larvae were found on corn plants on June 15 at Lincoln.

K. L. Coc'crhm- (June 5): The corn ear worm is begin-ing
to show up as a serious nest on early corn at Foley. A re-
port on one-half carload for market s .ov.-d approximately
85 per cent injury.

R. W. Harned (June 19): Corres-'ondents at Glendora, Tal-
lahatchie County, and Brooksville, I'o::ubee County, sent to
this office on June 13 and 13 specimens with the information
that those insects were abundant on young corn and were
causinC. considerable damage. This insect wvas also reorted
as causing considerable injury to the tomato crop at Long
Beach, on June 12.

'J. E. Hinds (June 23): The second generation of the corn
ear worm is moderately abundant in general. Parasitism by
Trichoer.-m.-a minut-in Riley is developing in the eggs more
numcrousl;, and earlier in the season than is the case with
cgr-s of Diatraoca :cchralis Fab.

SOUTHERN CORN STALK BORER (Diatraea zeacolella Dyar)

C. H. Brannon (June 26): The larger corn-stalk borer is
causing widespread damage to corn over the State.

J. R. Watson (June 22): The larger corn stalk borer is do-
ing considerable damage to corn in fields above Monticello
where rotation of crops is not practiced. The damage has
been aggravated by dry weather (F.W.Walker).

CORN BILLBUGS (Sphenobhorus spp.)

R. Hutson (June 15): On June 15 I saw an infestation by
one of the billbugs at Alicia, where these pests were taking
about one-third of a crop of 80 acres of corn.

H. C. Severin (June 10): Sphenop-ohorus aequalis Gyll. is
reported at 7White Lake attacking corn.

SOD WEBWOR01S (Crambus spp))

T. H. Parks (June 24): There was more damage to corn dur-
ing June from Cramnbus larvae than I have ever seen in one
year. The injury was general over the State and lasted un-
til almost the end of the month.

J. J. Davis (June 24): Webworms (Crambidae) were more often
reported attacking corn than any other insect. Reports were
received from May 23 to June 12 from Bluffton, Crawfordsville,
Decatur, Fra.nklin, Greenfield, Logansport, Matthews, Pittsboro,
Portland, and Tipton. Many other reports were received by
telephone fro-i Tippecanoe and adjoining counties.

J. H. Bigger (June 15): A very heavy moth flight of leather
colored sod webworms, Crambus trisectus Walk.,was noted con-
tinuing fro-i June 2 to June 10 in western Illinois. This
flight was observed during night driving.

W. P. Flint (June 20): Sod webworms have been reported
throughout central Illinois as causing serious injury. In
many cases the injury has occurred in fields which were in
oats in 1930 and which had become very grassy by fall. Very
heavy flights of adults are taking place at the present time,
the species most abundant being C. trisectus.

C. J. Drake (June 27): Sod webworms (two species) are ex-
treiely abundant at Toledo, many corn fields having been in-
jured.
W. A. Priae (June 25): Sod webworm has caused much damage
to corn and tobacco at Nicholasville, Muir, Litchfield, Tolles-
boro and Woodlawn. The moths are very abundant. They can be
gathered by the quart about porch lights at night in Lexing-
ton. They clog radiators of machines at night.








CLOVER

C. C. Co-pton (June 13): Adults of the green clover worm
are nuch -nore numerous than usual for the Des Plaines section
of Illinois. Thirty to fifty noths have been taken in the
moth traps every night for the past ten days.

C.J. Drake (June 27): The green clover worn is extremely
abundant throughout the State and doing considerable damage
to alfalfa, clover, and peas. It is causing a considerable
amount of annoyance on peas in gardens.


A LUCANID BE2TLE (Pseudolucanus dama Fab.)


R. H. Pettit (June 18): I received samples this morning of
Lucanus, probably dana, working in a clover field in Mecosta
County. The creatures are apparently swarming in great num-
bers in the clover field. The county agent at Big Rapids
writes mTe that the far-i is literally full of holes, or rather
this particular spot on the fa-n is literally full of holes.
They are worse in a spot of clover seeding, where every par-
ticle of clover vegetation was eaten into the ground, and
where they had worked the ground was as bare as a floor as
far as clover was concerned. This is quoting County Agent

M. H. Swenk (May 15 June 15): During the third weck in
May a field of alfalfa in Xeith County, seeded the preceding
August, was found to show many bare spots in which the alfal-
fa and the weed growth had both been eaten. An abundance of
the beetle T. confertus in this field indicates the possibil-
ity that it may have been responsible for the damage.

A PLANT BUG' (Adel-phocoris lineolatus Goeze)

C. J. Drake (June 27): The alfalfa plant bug is extremely
abundant in alfalfa fields in Story County and is spreading
rapidly in various directions. It seems to be migrating fast-
er northward than in other directions in the State. In some
alfalfa fields in Story County it is possible to collect then
in great nup3bers by sweeping the alfalfa. This insect was
first found in Iowa by Dr. H. H. Knight on June 18, 1929.

J. W. Ingram=and E. K. Bynum (May 29): A survey has been
made from Racoland to Lafayette and from Houma to Alexandria.
Beetle injury did not run over 1 per cent, except at Franklin
and at two sugarcane plantations. Around Franklin the injury
was 10 poer cent. On a plantation near St. Martinville one
field had damage amounting to over 40 per cent, the other
fields having about 15 per cent injury. At a plantation near
Morgan City one field had about 3 per cent damage.

W7. A. Douglas (May 27): Reports have come to the Rice Ex-
periment Station that the sugarcane beetle has been injuring
rice to some extent.

SUG'ARCA'TE BORER (Diatraea saccharalis Fab.)

17. A. Douglas (June' 15): Several examinations of cornfields
in the vicinity of Crowley were made last week, and heavy in-
festations were found in all fields except one. The stalks
were practically 100 per cent infested, and the damage was se-
vere enough to cause the stalks to die and fall over.

SW. E. Hinds (June 23): The sugarcane borer has started on
the second generation. The infestation is generally light as
yet although some centers of heavy infestation have been found
in corn which was planted early and is now in tassel and de-
veloping ears. Parasitism by Trichograma minutum Riley is
developing in the eggs of Heliothis obsoleta, especially,
and earlier in the season it was tound in the eggs of Diatraea
saccharali s Fab.

A. I. Bourne (June 26): Observations in local orchards and
reports from other sections of the State show the first evi-
dence of side-worm injury from codling moth within the last ten
days. This is very evidently due to the entrance of late appear-
ing first brood larvae,

N. Y. State Coil, of Agr., Weekly News Letter (June): Very
early in the month it was observed in the Hudson. River Valley
that pupa cases were much more numerous than in recent years.
By the 9th of the month approximately 10 per cent of the moths
had emerged. By the middle of the month hatching of eggs was
well under way in this part of the State and by the third week
in the month eggs were hatching in numbers in western New York.
(Abstract, J.A.H.)

N. J. State Coll, of Agr., Weekly News Letter (June): Records
from emergence cages indicate that at least 50 per cent of the
overwintering generation have emerged as moths in the southern
twvo-thirds of the State, By June 9 side worm injury had started
in southern New Jersey. By the second week in the month side
worm injury was observed to be much more abundant than usual, a
large part of the fruit in Glassboro district being heavily in-
fested. In one orchard in Gloucester County 100 per cent of the
fruit was injured by first-brood worms, with a high percentage
of the fruit containing as many as 8 "stings." The side worm
injury continued throughout the month. (Abstract, J.A.H.)

L. A, Stearns (June 22): The peak of the entry of first-brood
larvae occurred Juno 7-14. This brood at its peak is less abun-
dant than at the same time in 1930.

E. N. Cory (June 22): The codling. moth is very abundant.

W. J, Schoene (June 23): The codling moth is very abundant
at Winchester and heavy injury is expected. Dr. W. S. Hough
reports that the insect is expected to cause heavy d&muage in the
Winchester section, Eggs are being deposited in large numbers.

C. H. Brannon (June 13): Codling moth damage is very light
in the mountains.

C. H. Alden (June 22): The codling moth is very abundnat at
Cornelia. Weather conditions are ideal for multiplication.
There was a heavy carry over,

T. H. Parke (June 24): Hatching of the first brood commenced
the first week of June in Lawrence County. Some worms had left
the apples and were going under bands June 20. The brood is
quite heavy in most orchards of southern Ohio and two cover
sprays were advised for the first brood of worms during June,

J& J4 Davis (June 24): The codling moth infestations are the
most threatening for rnm.ny years* At Bedford the first pupa was
"found by Mr,, I-.r1shall June 18. At Lafayette the first moths
emerged June 2.

W. P. Flint (June 20): Emergence of adults from pupae of the
overwintering larvae has :-.rly ceased in the southern and cen-
tral parts of the State, There was a very heavy hatch of worms
the first part of June and a heavier infestation thla. usual
throughout southern and central Illinois.. In many well sprayed
orchards it is now very easy to find wormy fruit.. If the season
continues warm it will be one of the worst codling moth years we
have ever experienced. First larvae were t a n under bands in
southern Illinois June 17;' in central Illi.-.ois, June 18. ...

J. H. Big;er (June 15): The codling 'moth is very abundant in
Calhoun County. Still emerging from hibernation June 12.

W. A. Price (June 25): Codling moth is very abundant in
western Kentucky.

A. G. Rug;les and assistants (June): The codling moth is re-
ported as very oLbundmt from a 1-rge nru-ber of localities from
the southeastern part of the State. (Abstract, J.A.H.)


IM. H. Swe:k (May 15 to June 15): This spring the first over-
Swintered larva of the cocdling moth pupated on April 14. This
was one day earlier than the first pupation in 1930, 12 days
earlier than the first pupation in 1929, and 26 days earlier
than the first pupation in 1928. This early pupation would
probably have led to an early emergence of moths of the spring
brood if it had not been for the low temperatures prevailing
during May. As it developed, the first spring-brood r;.oth
emerged this spring on May 22, 14 days later than the ei.ergence
of the first moth in 1930, 3 d&ys later than in 1929, but one
day earlier than in 1928. Pupation of the overwintered larvae
steadily increased from April 14 on and oi June 15 about 85
per cent of these larvae had pupated. rner ence of the moths
increased from M ay 22 on, and on June 15 -.e.rly 70 per cent
of the moths had en.urged. Egb;laying began on May 26. On
May 29, 82 eg;s; by June 1, 270; by June 4, 426; and by June 15,
over 1,800 had been laid. by 193 moths. On June 14, 214 eggs
were laid, this probably representing the 'crest of egg-laying,
First "red-ring" stage eg-;s occurred on l.ay 29, first "black-
spot" egs on June 1, .and the first larva hatched on June 2;
by June 4, 16 h1ad hatched and on June 15 they were hatching
in very large mr-'c:rs.

P. M. Gilmer (June 27); The first brood: is just beyond the
peak of entrance at Wichita. Infestation is heavier than any
time in the last six years at this d-.te. Some poorly spr-yed
orchards already show 60 to 70 per cent of the fruit infested.
With normal conditions for the rest of the season the third
brood should be by far the heaviest in the history of the valley,

in the Hudson River Valley, In Dttchess County practically
100 per cent of the fruit was scarred by June 3. This very
decided acceleration of the plum curculio is attributed to very
warm weather which prevailed from May 26 to 29 and from June 2

(June 15): The first adults of the new generation emerged from
the soil today. This is 9 days later than the first emergence
in 1930 and 19 days later than the first emergence in 1929.
There has been, no rain in peach orchards of this locality during
the past 5t weeks, and therefore this record of first curculio
adult emergence is perhaps earlier than that under orchard
conditions, as we have kept our pupation boxes watered at inter-
vals. The dry weather had retarded the ripening of the fruit,
causing the harvesting season to be later than anticipated
earlier in the season. On that account the latest variety of
peaches in this locality, the Elberta, may not escape a second-
brood curculio attack. We are not expecting any second-genera-
tion eggs inr the fiebid until July. (June 19): Adults of the first

New York


Vcrmnont


R. D. Glasgow (June 22): I was impressed with the unusual
number of pine, hemlock, and spruce trees which apparently
were recently dead from borer injury and which still retained
the reddened foliage. Large number. of trees also showed
from one to many branches with reddened foliage, indicating
borer work, An incrca.c-d amount of borer injury is to be ex-
pected following the past two seasons of unusually dry we.ther.

ELM LEAIF BEETLE (Galcrucella xanthomelaena Schrank)

E. P. Felt (June 23): Eggs and small grubs occur in south-
ern ITev.w England. The insect is somewhat later than usual.
The trees have developed a very abundanit foliage, and this
may result in reduced injury as compared with last year.

Providence Journal (June 9): This insect pest is known as
the most important leaf-eating enemy of the elm, and it is
prevalent in Rhode Island in great numbers this year because
the long drought of 1930 enarLbled it to survive the winter
cold more easily than usual.

these plots of the Sierra iTational Forest have been atta-c_'cd.
As the winter of 1930-31 has been one of the driest on record,
these plots will afford an excellent opportunity to study the
effect of moisture deficiency on an increaLsing infestation of

MEXIC.AN 3JUIT `70F: (Anastreo:h- ludens Loew)

The outstanding develotr.ct on the Mexican fruit worn project during
the month of April .*',s the fin-.in- of infestations in locally grown fruit
in Mataroros and in fruit produced in a qrove near Mission, Tex.
The Matanoros infestation was discovered April 9, in sour orpnos
produced in the patio of a house at 3th and Horr:r. Streets. The fnruit
produced on these prermises was heavily infested during the season 1929-
30. Although traps have been maintained in these trees continuously
since October, 1929, no adults have been caught since Anz-ust 20, 1930.
Upon finding this infestation a thorough examination was r;eof all
fruit growing in Mtanoros. This inspection showed no indication of
other infestations. However, on the 15th and 16th adults were cau-ht
in traps located at a distance of 11 gn3 5 blocks, respectively, from
the infested premises at 8th and Herrera Streets, one adult being cap-
tured in each of the two traps. Immediately upon the determination of
the infestation and in cooperation with the Mexican inspector at Natanoros,
the work of stripping all citrus fruits from the trees was started. Very
little opprcsiti.on to this work on the part of the citizens of Matmroros
has been encountered.
On April 22, a report was received of the finding of three '--?ots
in a grapefruit from a grove northeast of Mission. Upon c'-.ckin" the
grove from v:hich the fruit originated some two or three bushels of
fruit were found stored in a box filled with sa.nd. An inspection of
this fruit resulted in th-e findia, of one larva, and on screening the
sand in which the frait had been stored., five rTrp.%C were found. T: is
fruit and the sand in :which it -had been stored were inr.ediately treated
and buried, as were some nine boxes which wore bein; held in sto-as-e
within about one-h-alf nile of the point of infestation. A thorough
examination of all other fruit held in storage in the valley showed no
indications of further infestations.

WINK BOLL WOPM (Poctinophora -ossypicella Saund.)

In order to determine the activity of the pinh boll' 3r01 in the
Salt River Valley, Ariz., two li.ht ':r?.ps and two fligLht screens w-ere
used, but no moths have been tkc-ni. The i.:spection of cotton sqLares,
however, yielded 5 larv-_Ac of the pi7'nk boll worm on 1ayTh 5. The field
where the species were tken was rather w-c*t.v'ly invested l-.ct year,
and the infested squares were from stub cotton. ?rep.,rations are now
being made to destroy the cotton in that field. Three a&ditinnal worms
were found in an adjoining section on May 6. These findings; -re the
first in that area in the 1931 crop of cotton.

On April 17 the United States Customs Mxamincr in PhAil-delphia call-
ed the attention of our inspectors to a case containin- antiques from
Syria packed in raw cotton. The cotton was rernoyed and e';celsior sub-
stituted; half the 36.5 pounds of cotton was examined and all seeds re-
moved from it, the whole lot being then destroyed by burning. Dead
larvae were found in 18 of 100 seeds, and in the nineteenth a living
larva was found. The- remainder of the seed was forwarded as an inter-
ception to Washington. Reports on both the. larvae found a.nd the seed
subMitted now verify thie presence of the insect in both cases. This
case is of special interest, not only because it is a first record of'
the finding of live larvae of this insect at the port of Philadelphia,
but also because of the unusual attendant circumstances. The case of
antiques would normally have little interest for our inspectors and- we
are indebted to the Customs officials for bringing the matter to our
attention. It may be added that this helpfulness on their part clearly
implies a very encouraging degree of understanding and cooperation be-
tween the two inspection forces in this port.

GIPSY MOTH (Porthetria dispar L.)

Infestations have been found in four. towns in Connecticut and in
three towns in Massachusetts. The most serious infestations in the
Barrier Zone have been found in the towns of YTew Marlboro, Sandisfield,'
and Sheffield, Mass., and in the towns of, Canauan and Salisbury, Conn.
During April, nine crews scouted in four towns, and two infes-
tations were found in the town of Milan, but as the work in this town
has not been completed, the size of these infestations is not known.

JAPA ESE BYDSLE (Popillia japonica Te.wm,)

Four thousand three hundred and sixteen Japanese beetles were
collected in and near 500 traps placed in Cape Charles, Va., between
May 20 and August 30, 1930. The infestations are comparatively light,
but fairly continuous throughout the town. A representative of the
Moorestown Japanese beetle research laboratory spent several days in
Cape Charles while the treating operations were in process, but failed
after repeated diggings to locate any larvae whatever in the treated area.

INSECT C01iTDT101TS IT FO0TO RICO :,Rli:.1 LAY, 1931.
I. D. Leonard
Insular 27pe-riment Station, Rio Piedras, Porto Rico.

Infestation counts of a ztu.arcane scale (Aspidiotus sacchari Ckll.)
obtained from examining 100 cut pieces of cane each in four parts of a
small 'experimental planting of 5:; 10-12 at iTv._nabo on May 9-10 showed
an average of 11.25 per cent infestation. Some pieces had several nodes
quite thicef-ly encruste.. Many scales had been killed by a black fun as.
(M.D.L.)

Adults of a scarabaeid beetle (Z-scinetus barbatus Fab.) known to
attack suf-arca-Le were first noted in abundance at lights at Isabela on
April"20 and became very abundant for a few weeks. On the night of
May 17 only a few were' present and a few nights later none was observed.
(M.D.L.)

The change (Scapteriscus vicinus Scudd..) did about the usual amount
of damage, approximately 15 per cent, to young tobacco plants in the
field throughout November and early December, 1930, in the Juncos-Las
Piedras section. This insect destroyed about 50 per cent of the young
plants on a 1-acre planting of rice, the damage starting in April and
continuing up to May 8. About 3 acres of rice planted in the same place
in early April, 1930, were entirely destroyed by early in July of that
year. (J. Gomez, Agricultural Agent at Humacao.)

Climbing cutworms were more injurious to tobacco than, usual, about
20 per cent of the young plants having been killed in the Juncos-Las
Piedras section during Tovember and December, 1930. (J.3.)

The melon worm (Diaphania h'valir.ata L.). was found >cvily infesting
the foliage of :.-.clon and cantaloupe in a field near Aguadilla about the
middle of May. (M.D.L.)

The lima bean pod borer (Mar2ca testulalis r-e2':'r) was absent in the
last count of 100 lima bean pods, althou-gh earlier in the month it had
been present. (G, N. Tolcott.)

A pod borer (Etiella zinckenella Treit.) infested about 12 to 15
per cent of the lima bea.n pods during the month, but the last examination
of 100 pods on Iay.- 29 cho'.red no infestation at the Isabbla Substation
experimental plots. (G.1Y.W.)

The scarabee (1i scenes batatae Waterh.) was fourd to be bauly in-
festing several sweetpotato t..bers received b."1" v-i] Molinary at Caro-
lina on May 18 for use as seed from the Federal Ex-c'riment Station at
Mayaguez. Both adults and larvae were ab'nr.-nt in the tubers. (M.D.L.)





-318-


The sweetpotato leaf miner (Agromyza ipomneae Frost) wa.s observed
moderately infesting two small plantings of sweetpotato at THrnacao
Playa on May 10. A few sweeps of the net showed the flies to be common
in the plantings. (M.D.L.)

A leafhopper (Empoasca sp.) was causing slight but general stippling
of the leaves on two small plantings of sweetpotato at Humacao Playa on
May 10; all stages of the insects were present on the undersides of the
leaves.

Examined on May 5, at the Isabela Substation, an experimental plant-
ing of about one-half acre of alfalfa which was nearly ready to cut and
found it generally infested with a leaf-ter (Dichomeris piperatus sIrsm.),
many of the larvae being tied together and badly eaten. Danage as a
whole was only moderate, however. (M.D.L.)
The bean lacebug (Corythucba ossyi Fab.) was found to be moder-
ately abundant on several young grapefruit trees on the Isabela Substa-
tion ground on May 5. The yellow stippling of some of the leaves in-
volved almost their entire surface. We did not notice any other host
plants of this lacebug near by. Mr. Wolcott. stated that he had first
noticed the infestation about a week earlier. This is the first record
of the insect affecting citrus in Porto Rico. On May 8 a number of
srjali g "o
leaves on severalhgrapefruit trees at the Insular Expcriment Station
at Rio Piedras sho ied characteristic yellowing, but very few of the
lacebugs could be found on them. These trees were -'rowing under several
large Anona muricata trees which were moderately infeItd.d at the time.
(M. D.L.)

Considerable damge by June beetles (Phyllophaga spp.) to the
foliage of young -rapefruits in two demonstration plantings of about
1 acre each was reported during sarly May (J.G.).

A scale (Pseudoparlatoria ostreata Ckll.) was observed as abundant
on several good-sized papaya trees at the Isabela Substation and almost
entirely encrusting some of the trunl,-s and branches and several of the
fruits. This scale was observed. to be commonrpapaya at Ponce and
several other localities on the zouth coast in September, 1930, but was
not identified at the time, It has been specifically recorded -from Porto
Rico previously only from Maeyaaez by Van Zwalu;7 enb'rg on Solanum sea-
forthianum and Acalypha sp, (M.D.L.)

Caterpillars of the cotton loaf worm (Alabamna argillacea Hbn.)
became abundant on cotton around Isabcla about May" 21 and most farmers
are spraying or dusting. NTone had been noted around Ag.uadilla up to
May 29. (G.NT.W.) E. t. Rorke of the San Juan Ginnery Company reports
that infestations on cotton started during May in several sections on
the north coast, but that these were promptly checked by7 the use of
insecticides. (M. .D.L.) A few' mot'is wore noted at light near Aguadilla







-319-


on June 5, 8, and 9. These are in no sense mi..rtory records, because
of the small number of individuals notec in each cas. (.'..)
3x?..inh.tion of cotton fields around Carolina. and Rio Grande, both
in the hills and1 alon:- the coast, indicated infestationis of the ink:
boll -.worm (Poctinophora qo,,'_icil S:r;:. ) of from 75 to 100 pe: cent
on May 12. Cotton fields around 1'1an-:.;jo on MLay 13 'cre so heavily
infested that two had to be abandoned and a t'ird wvas in such bad share
that little cotton v.'ould be obtained from a second pick.in7. Cotton
fields around Patillas and Guyrama on May 13 ;wore from 80 per cent to
100 per cent infested in most cases, although a fe7 small fiec Ids had
infestations as lov< as 25 to 30 per cent. The avera-e for thiis dis-
trict :as aroi'-.id 90 per cent. (JE.N.W.) T'o infe t.tioi counts on a
field of cotton in Ca-uy 'j-.scc on e.v. n-tion o 100 bolls e.,tch'
s'o-.7ed, on May 1, 6 per cent infestation and on Hay 8, 10 per cent
infestation. By the end of the nonth there was a Teneral li.ht infes-
tation over practically the whole of thie north coast cotton-;rov7inT
section at Ca&nvy, Hatillo,and Ar-.cibo. (. T.HR.)

On May 5 a requaect was received front Ponce for control ne"suares for
June 'beetles (P21yllo:'a.a spi. ), the statement bein" r.aidc. t:.at the beetles
had been drajirc the roots of several rose bushes by burrowing into the
soil at the base of the plants for r-r-'xse of eT- laying.
