INSECT PEST SURVEY BULLETIN

OUTSTANDING EUTOM.OLOGICAL FEATURES IN THE Tj ,T-D S.TATS FCR JULY, 19?

The grast-hopper outbreak anticipated in the last nxr-ber of the
Survey bulletin has developed to quite serious proportions in western
South Dakota, Nebraska, and Kans-,s.

Throughout the greater prt of the country cutworms continued to
be of but little irmortr.nce during July. During the latter F'-rt of June
and the early p-rt of July, however, an unusual amount of d:'.-e w-.s oc-
casioned by them in ,aine -rnd quite a severe outbre-:- de\eloEda on the
overflowed land in the northern Willnrette Volley in Oregon.

The fall armyrorm beca-me extremely abund:.nt in r,-rts of Tr-xas dur-
ing the first w-eek in the month :,nd about the middle of the T.onth it
was repotted as doing serious damage in mn:ny localities in 'issis--:ippi.

The rose chafer appears to be unusually trouble :ore this Ecaszn
in several more or less isolated locrLlities in the northern .-nd Centr-Ll
States, reports of serious d-r..re having. been received from :.c. York,
Indi-n'-, Wisconsin, and '!ebr.aiska.

The a'bnorrr-:.ly lprp.e number of wireworm reports recor-cd i.. the
last number of the Survey bulletin is nu'-cnted this month by rcrorts
of heavy darr.g e from .' ine, Nv. York, r'ncPs, -ind :;br :2.

Since the low ebb in ibundA.nce of chinch bu.s, which oc,'urrcd be-
tween 1917 and 1919, this insect has not re-.chcd o low a 1c- .1,.tion
record as is reported this year.

States. Illinois reports this insect two weeks later than last year and
the Ohio records are approximately three weeks later.

The Oriental peach moth continues to be at a low ebb throughout the
greater part of its range. It is now recorded as far east as jFredonia
in ITe' York and has been definitely located at Lake City in S.0iC.


Although the plum curculio still continues to be subnormally abund-
ant throughout the greater part of the Eastern States, present conditions
in Georgia indicate that there will be a heavier population after the
peach season this year than has occurred for several years owing to poor
weather conditions intdrferinr with effective spraying, and reports from
Illinois indicate that this insect is above normal in the southern part
of the State.

Throughout the raspberry-growing section extending from Ohio and
New York into Ontario the ricpberry s.wfly isdoing very considerable
damage. .... .

A rather serious grape root worm outbreak developed in Nev, York
State and extended'into Berrien County, Michim-n.

The strawberry root aphid has increased so rapidly in the straw-
berry-growing section near Chadbounn, N. C., that it is a serious eco-
nomic factor in that region.

Although the early indications were that the M.exican bean beetle
would be subnormally abundant in the originally infested areas, because
of lowtwinter survival, subsequent conditions have caused this insect to
increase enough to offset the winter loss. During the month the insect
spread rapidly across eastern Maryland.

The elm leaf beetle appeared in serious numbers at Troy and in the
suburbs of Dayton. This pest appears to be confined to the Miami Val-
ley in the southeastern part of Ohio. No reports have been received
from other States this year.

The usual number of reports on termite dimznge were received this
month.


OUTSTATITTG ENTOMOLOGICAL FEATURES IN CANIADA FOR JULY, 1928.

Reports indicate that the onion mn.,L-ot is more troublesome than
ucsul in Ontario, sections of New Brunswick, and in. southern Sraskatche-
w-n and 14L nitoba.

The outbreak of the roadside grasshopper, Camnula pellucida Scud.,
is affecting r,-ibn-., rraszes and grain crops at Riske Creek, Ga.rng Range,
Alkali Lake, Do, Creek, and Big Bar Range, and Stump Lake in the Nicola

Valley, British Columbia. Over most of the province, outside of the
above areas, there has been much rain and no grasshoppers are in evidence.

Wireworms are more abundant than usual in Ontario on a variety of
field crops.

Reports indicate that the rose chafer is less abundant th-n in for-
mer years in southern Ontario.

The potato flea beetle is prevalent throughout the St. John River
Valley region, New Brusnwick, but scarce along the Northern Strait and
Miramichi Valley region.

Garden slugs of the species A.riolirmax arestis are present in
serious numbers in field and garden crops in the Agassiz and Chillir:ak
Valleys, British Columbia,

The raspberry sawvfly has rarely, if ever, been more injurious in
raspberry plantations in the Niagara district, Ontario.

The cigar case bearer has increased in abundance in Ontario over
last year and occurs almost all over the province in neglected orchards,
in some of which almost every leaf is attacked. It is reported as very
prevalent in orchards in the Annapolis Valley, Nova Scotia.

The species Laspevresi2 nackardi Zell. has beco-r.e a seri ous cest
in sour cherries, in recent years, in the Sranich district, Vincouver
Island, British Columbia.

No heavy infestation of the green apple aphid has been seen any-
where in Ontario this season. Last year one of the worst outbreaks on
record occurred.

The fruit tree leaf roller is much more abundant in Ontario this
year than usual and is found in almost very county **.here fruit is
grown to any appreciable extent. The eye-spotted budmoth is '-lso more
abundant than usual throughout the fruit districts of the province.

The satin moth occurs over the entire Lower Fracer V-lley :'.nd over
the east coast of Vancouver Island, Pritish Columbia. The infestatio:n
is very serious this year, especially on native cottonwood. It is atf
tacking all species of poplars and is also very noticeable on ntive
willows.

The lilac loaf miner Grncilari, syrinellia Fnb., now nprc.rs to Ic
established throughout Ontario.

The spruce budworm has heavily infested Douwlas fir in cert,?.in
sections of Vancouver Island, British Columbi;..

Cnnkerworms have been present in t'undance in the Annapolis V:l-
ley, Nova Scotia, and have t completely striped many unsprayed orch.-rds.

16, the next day from Choctaw, and the next from Yalobuchp. Gras-
worms havw b,>n reported from iinds, Alcorn, Lee, DKtibbeha
Delato, Chickasaw, Prentiss, -_.rd }'.onro,; Counties. The worms are

C, R# Crosby and assistants (July): Very serious injury to
fruit and truck as woell as ornamr:ntals in parts of W7aync Coun-
ty has been reported this year, also slight damage in Orange
and Greene Counties. (abstract J.AH.)

J. J. Davis (July 27): The rose chafer was reported from vari-

:.onterey; prv-ent by the millions and devouring every green apple
in a 10-acre orchard at Ray; and abundant at Grown Point,

E* L, Charmb-rs (July 25): Specimens of the rose chafer have
been received from a dozen or more sources in southern counties

Iew York


JL.braska


J, H, Haw!kins (July 13): We have found that clover baits
were effective in attracting the adults of the wheat wircworm
Agriotes mancus Say and give some promise as an auxiliary
method of controlling these pests. Wheat wireworms were found
April 18 at Holden in the first 6 inches of soil, although the
ground was still frozen beneath the top layer of 6 or 8 inches.
Reports of wireworm injury to potato seed pieces during June
werQ received from W::,rrcn, Wiscassct, and Tciport. Potatoes
were so badly injured on a farm at Cape Elizabeth that replant-
ing was necessary#

F. B. Morris (July 18): Wireworms caused much damage in some
cornfields; in one case 60 o-r cent being destroyed in Os-'.o
County.

M. H& Swenk (June 15,July 15): Present indications are that
there is a general but light infestation of the wheat stubble
with the Hessian fly over southeastern Nebraska, and bc:use
of the abundance of rainfall that we are having and the heavy
volunteer wheat growth that is develpping, the situation is be-
ing most carefully followed.


CHINCH BUG (Blissus leucontemrus Say)

Mt H* Swenk (June 15-July 15): The chinch bug did no,.commer-
cial damage to crops in Nebras]ha this yoar. Not since the very
low cbb in abundance of the chinch bug during the years 1917
to 1919 has there been so little eviJ'-icu of this pest as dur-

W, P* Flint (July 21): As has been the case for the past sever-
al seasons, large numbers of the common stalk borer are being re-
ceived daily, In most cases these insects are sent in with the
thought that bhey may be the European corn borer,

E, L. Chambers (July 25): Many specimens of the stalk borer
have been received during the past week. It was reported by sever-
al correspondents as being unusually injurious to hollyhocks and
one report stated that it was playing havoc with beans.

J, W. McColloch (July 20): The common stalk borer is again caus-
ing considerable damage to corn in Kansas. Rainy weather and heavy
-.ced growth last year are partly responsible. About the same in
abundance as compared with an average year.

H. C, Severin (July 12): Sent in with the fear it might be te
European corn borer. Damage being very small in the eastern half
of the State,

M& Ho Swenk (June 15-July 15): The stalk borer was frequent-
ly sent in for identification, or its injuries were complained
of during the last half of June and the first half of July, These
reports have come in from all parts of the eastern one-third of

cane moth borer is extraordinarily scarce this y.-ar. Fields
of corn and sugarcane have b.-n _':a:ined and no torers fo-..

of the month considerable damage was reported from Greene
County, though in general but little sideworm was observed
throughout the month. In Clinton County considerable side-
worm injury was observed on the 16th, and in the western
part of the State sideworm injury became quite conspicuous
late in the month. (abstract J.A,.H).

E, Lee Worsham (July 23): The codling moth is not so
abundant as last year. The egg parasite Tricbogramrna
minutum Riley has been introduced in the apple growing re-
gion of northern Georgia and about 95 per cent have emerged,
The introduction is very successful so far as can be told
at this time.

T, H. Parks (July 23): Emergence of the spring brood
of moths occurred at Columbus rather regularly between
May 18 and July 9, Worms began leaving the fruit the week
of July 10, with the first pupa observed July 15, Sprpying
is advised for central Ohio during the last week of July.
The broad is much lighter than usual in the southern half
of the State, with a very few worms being taken under the
bands by L. A, Stearns in Lawrence County.

S. C, Chandler (July 21): Codling-moth adults of the
first brood are now emerging in central and southern Illinois.
Emergence started in southern Illinois on July 9 and in
central Illinois July 14. This is nearly two weeks later
than normal. While the first brood worms were not so abun-
dant as usual, unsprayed orchards show an average infesta-
tion of from 15 to 20 per cent, and with favorable weather
it is possible that this infestation will reach close to
100 per cent before the end of the season. The last moths
from overwintering larvae emerged Juno 26 at Carbondale#

M. H, Swenk (June 15-July 15): The first brood of the
codling moth began its emergence at Lincoln on July 13,
about a week after the disappearance of the last moths
of the spring brood in our rearing cages,

Ea J, Newcomer (July 4): First-brood moths began appear-
ing at Yakima July 4. The first spray for the second brood
of v/orms should thus be completed by July 12. On account
dfthe protracted warm spell in May it was suggested in the
June Bulletin that a higher percentage of wormy apples
might result than usual; pretnt indications are that this
will not be the case, the warm weather having been followed
by a long period of abnormal cool, windy weather, which
apparently offset the effect of the warm weather,

J. E. Graf (July 30): As far as our reports through corres-
pondence and other sources are concerned in regard to the
1iexic.-n bean beetle, this pest now infests all of the State
of Maryland, making its/!Lpparance on the Eastern Shore and
southern Ma.ryland this season. It has been reported that it
was particularly destructive in some sections of southern
Maryland and in the vicinity of Annapolis.

Miss Van Horn (July 15): L.ast year the Mexican bean beetle

real loss.

E. L. Chmbcrs (July 25): "any complaints have been re-
ceived that sweet peas are being heavily att.ac'r-c-d by the pea
aphid, rhey seem to have suddenly appeared simultaneously
throughout the southern part of the State on or about the 15th
of July.

J. E. Dudley, Jr. (July 24): The abundance of this insect
on peas and alfalfa is fluctuating greatly but at this time
there seems to be less than one-fourth as many as last month,
being only half the number that occurred last year in Columbia
County. Coccinellids are numerous, but not so abundant as
usual; syrphids began to iocrease noticeably about July 1 and
at the present time are much more abundant than usual. Several
mornings they have Leen so thick on the ground that a continual
buzzing as of a hive of bees resulted. Adults have been col-
1ected by the hundreds with a hand net. I.abis ferus is more
abundant than usual. Parasites, chrysopids and fungus disease
are much less abundant than usual and have played little part
in control.


CUCui"BERS

STRIPED CUCLUIFER EETLF (Diabrotica vittata Fab.)

J. H. Hawkins (July 13): The striped cucumber beetle was
attacking cucumber and squash plants at several places in the
State during the first week in July.

C. R. Crosby and assistants (July): In general, this insect
seems to be normally abundant throughout the central and west-
ern part of the State and was reported as unusually abundant
from Monroe and Oswego Counties. (abstract J.A.F.)

C. C.Cor.pton (July 14): The striped cucumber beetle is much
less abundant than usual. It has not been necessary to use any
control me.R..ures in Cook County this season.

J. E. Dudley, Jr. (July 21): This insect was late appearing
and did little dlmr.Ze to seedling cucurbits wing to the frequent
rains occurring during the short period when cucurbits are most
susceptible to its attPck (Kcenosha County). (Juno 15-July 1):
On account of the heavy precipitation, it was impossible to
v:i.k in many fields for a week or ten days to treat the bee-
tles, and by the middle of July they were decidedly scarce in
cucurbit fields.

H. C. Severin (July 12): The striped cucumber beetle ap-
pears to be very severe all over the State.

Agriculture, that the risk of intoducing this pest into the
United States is no longer involved in the importation of
Christmas trees and greens from that Province, Acting Secretary
Marvin, on June 27, under the authority conferred by the act
of Congress approved August 20, 1912 (37 U.S. Stats. 315), re-

PACIFIC RED SPIDER (Tetranychus pacificus MeGregor)

E. A. McGregor (July 23): Probably the worst pest of shade
trees in the great SanJoaqdain Valley of California is the
Pacific red spider. There are:facts which indicate that the
sycamore tree, Platan-s racemosa,, may be the native host of
this mite. Very severe injury occurs every year to a certain
percentage of these trees, resulting at times in almost com-
plete defoliation. The Chinaberry or umbrella tree, is the
commonest ornamental tree in the cities and towns of central
California.. Frequently the streets are lined solidly with
these trees. Almost every summer the Pacific red spider be-
comes so abundant on the chinaberry trees as to cause very
heavy shedding of foliage, resulting commo-aly in the loss of
their shade value. '.CertanThiti6ao (LizdEsy for '6iapJ6
maintain a department of pest control for the almost exclusive
purpose of combating this pest. During the present season
every tree in town has been sprayed at least once, and many of
them twice. The present correspondent has for the past several
years conducted an incidental study of this pest and hopes to
publish on it eventually.
