THE MORE IMPORTANT RECORDS FOR JULY

Grasshoppers continued to be the most serious problem of the year. Rather
heavy migrations were under way over much of the infested area. In the southern
part of this area--Nebraska and Colorado--the outbreak was probably as heavy and
widespread as the outbreaks in the late 70's.

A slight outbreak of Mormon crickets occasioned considerable alarm in the'
Dakotas during the month. In the western part of the range of this insect egg
laying began the second week of July.

The Japanese beetle was appearing in unprecedented numbers. Around the
periphery of the infested area reports of heavy emergence have been received
from the metropolitan area surrounding New York City, and from Connecticut,
Rhode Island, DIaiaare, and northeastern Maryland.

The recently introduced weevil Naupactus leucoloma Boh.'reached its peak
of emergence the second week of July. In some fields in Florida it was emerging
at the rate of about 500,000 beetles per acre. The insect was discovered at
Laurel, Miss., on August 9.

Another weevil but recently reported from this country, Calopjycterus
setarius Roelofs, again appeared in numbers in parts of Connecticut.

A heavy outbreak of the variegated cutworm occurred in Wisconsin, Minne-
sota, Nebraska, and South Dakota. In Mlany places the outbreaks were unprece-
dented.

Unusual numbers of the sugar beet webworm were reported from North Dakota
and the Groat Basin States.

The white-lined sphinx appeared in startling numbers over a very wide area
extending from Michigan westward to the Dakotas and Idaho.

Serious armyworm outbreaks occurred over much of the United States, reports
having been received from the New England, Middle Atlantic, East Central, West
Central, and Great Basin States.

The European corn borer was much more destructive than last year in the
New England States and New York.

Codling moth abundance was variable, New Jersey reporting the heaviest
infestation since 1933 and Delaware the lowest since 1929. In general, in-
festations appear to be about normal.

The flatheaded apple tree borer is still destructive over much of the
area that has suffered secure drought during the last few years.

Blister beetle injury was reported generally from New England to Kansas
and the Galf.

Serious damage to tomato fruit from the corn ear worm was reported from
the Middle Atlantic and East Central States. The usual damage to sweet corn
is being generally reported. The infestation in southern California is ap-
parently increasing.

Unusual injury to potatoes by leafhopper was reported from the Middle
Atlantic States and from some parts of Indiana and North Dakota.

From New York westward to South Dakota the imported cabbage worm was
generally destructive.

False chinch bug attacking sugar beets is reported from Idaho south to
Arizona and- east to Oklahoma and Texas.

The boll weevil is causing more damage in South Carolina than it has in
a number of years. Infestation,is also quite heavy in northern Georgia. In
the Gulf region, although populations are not unusually high, weather favor-
able for weevil development has increased the hazard. Heavy infestations are
also reportedC from eastern and southeastern Texas.

Cotton flea hopper damage was reported from northern Georgia westward
to southern Texas.

A half-grown cotton leaf worm was found on July.22 in southern Georgia
and one on July 13 in southern Alabama. Up to August 2, however, no leaf
worm had been reported from Louisiana or Mississippi.

Gypsy moth infestation in New England is heavier than it has been for
many years and very serious defoliation is generally reported.

Severe defoliation by the forest tent caterpillar is also reported from
New England and Minnesota,

Cankerworms are generally reported from Ne, England, and the most
serious outbreak of the spring cankerworm over to be reported is under way
in Nebraska.

The bagworm is generally prevalent from New England and the East Central
States southward to the gulf.

A heavy infestation of the spruce budworm on ponderosa pine is reported
from Colorado.

THE MORE IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA



In areas in Saskatchewan where crop conditions have been poor, and
control measures consequently generally neglected, grasshopper ravages
were completing the work of the drought. Local dispersal of the insects
resulted in severe defoliation of remaining crops throughout west-
central and northwestern parts of the Province, with heavy reduction in
feed supply for livestock. Infestations are spreading north and north-
eastward into many new districts. In Alberta there was little loss from
grasshoppers up to the end of June and the use of poisoned bait was
proceeding with satisfactory results. However, with the advent of hot
weather in July, the grasshoppers were migrating into grain fields, and
some districts reported losses in spite of the stenuous poisoning
campaign. Toward the middle of July hoppers were migrating into southern
Alberta and losses were increasing in dtier sections, particularly in the
southeast. Severe damage was still occurring in southern sections, in
the latter part of the month, in,:.spite of recent rains. In Manitoba the
distribution of poisoned bait was necessary only in the extreme south-
west, and excellent kills were obtained. Late in July, grasshoppers in
the Red River Valley were reported dying of fungous disease. By mid-
July, a large proportion of the grasshoppers over extensive areas of the
Prairie Provinces had reached the adult stage.

In areas of Saskatchewan and Alberta affected by extrer,2e drought,
the destruction of host plants may result in a marked reduction of the
wheat stem sawfly population, and reduce the economic importance of the
insect in such areas for some time to cone. In the Rockyford, Nobleford,
and Barons districts of Alberta, wheat is severely infested.

The armyworm is causing considerable loss of excellent stands of
oats, other grains, and grasses in a wide area in eastern Saskatchewan
and has defoliated some fields of oats and barley at scattered points in
Manitoba.

Severe outbreaks of the western chinch bug occurred in old brome-
grass pastures in the Red River Valley, Manitoba and, where the insects
attacked wheat in numbers, completely destroyed the crop.

Weather conditions in southwestern Ontario were ideal for pupation
and emergence of the European corn borer. The first moths and egs were
found at Chatham on June 28.







-266-


Extensive outbreaks of blister beetles of several species again
c;ccurred in the Prairie Provinces. The abundance of these insects is
reporters tr be associated with repeated outbreaks of grasshoppers, on
the e.g ;ods of which the larvae feed.

The Coiorado potato beetle appears to be more abundant and in-
jurious than usual in Ontario and parts of Quebec. A marked reduction
over previous years is noted in iManitoba.

Heavy infestations of flea beetles of several species were reported
on field aind garden crops in various parts of Eastern bCanaOa and in
Manitoba.

Important damage by the cabbage margot wvas reported in Ontario and
on Prince EdCward Island. In the latte&r Province and in eastern Ontario
the onion maggot is also causing notable 'injury.

Extensive flights of the diamondback moth occurred in southern
Alberta and Saskatchewan in spring, and the larvae have caused rather
severe damage to cruciferous crops.

The first brood of codling, moth w;as heavy in southern Ontario,
as a result of the large carry-over from 1936. There were no serious
worm infestations, however, in well-sprayed orchards.

The infestation of oriental fruit moth continues very low in
peach orchards of southern Ontario.

The apple 'vphid and the black cherry aphid are troublesome in
orch,.rCs of the Okanagan Valley, British Columbia.

An infestation of the spruce budrworn is present over a large
territory in Manitoba and Ontario. It apparently extends from the
Sandila.nds Forest Reserve, Manitoba, to the Eagle River, Ontario, and
appears to be spreading eastward.

The spruce mite, which has long been a serious pest of planted
spruce in the Prairie Provinces, has this year assumed outbreak< pro-
portions, and reports indicate that defoliation is proceeding rapidly.

An extensive and injurious infestation of the yellow-headed spruce
sawfly has developed in northern and central Manitoba, .Saskatchewan, and
Alberta.







-267-


The European pine shoot moth, which was 1a.rgely eliminated in the
Niacara. district, Ontario, by the severe winter of 1933-334, has recover-
ed and increased to a somewhat alarming extent.

Severe defoliation by the satin moth is reported on Prince Edwar.rd
Island nmd Cape Breton Island. Defoliation also occurred at Mor.oton
and in Wcstmnreland Cunnty, New Brunswick. A new infestation was dis-
covered at McAdam, New Brunswick. Little dam.-;e was done this year at
Amherst, Nova Scotia, ,-here the outbreak has beocn much reduced.

G E NE R A L FEEDERS

GRASSHOPPERS (Ac'rididae)

Vermont. H. L. Bailey (July 26): The lesser migratory grasshopper (Me-
lanoplus atlanis Riley) is abundant in West River Valley, Windham
County, southeastern Vermont.

Georgia. .0. I. Snapp (July 1): 'Grasshoppers originating in wheat stubble
have moved to adjoining cotton and corn and have caused considerable
damage 'to those crops at Marshallville, in central Georgia. (July
13): Grasshoppers are unusually abundant and have caused consider-
able damage to old corn at Fort Valley.

C. H. Alden (July 19): Severe damage to corn by grasshoppers.
Most abundant species were M. differentialis Thos. and Dissosteria
carolina L. Grasshoppers are generally more abundant and injurious
in the southern half of the State than they have been in many years.

Florida. J. R. Watson (July 23): Grasshoppers, particularly the so-called
"bird grasshopper" (Schistocerca americana Drury), did much damage
in the northern part of Alachua County, where corn was badly riddled
over a considerable section.

Ohio. T. H. Parks (July 22): But one report has reached this office con-
cerning grasshopper damage. This came from Brown County, southern
Ohio, where the insects were reported injuring tobacco and soybeans
on a farm. During the wheat-insect survey grasshoppers were found
to be present in only moderate numbers.

Indiana. J. J. Davis (July 26): Grasshoppers are abundant in more or less
isolated spots throughout the northern half of the State, with great-
est prevalence in the western pprt, especially near the Illinois
State line. Although most of the trouble is in the field crops, a
number of reports of injury in gardens were received the first half
of the month.

Illinois. W. P. Flint (July 21): Grasshopper damage continues to be
moderate over much of the infested area in the State. There is
considerable migration to corn and soybeans, now that the small
grain is being cut. Hoppers in all cases are showing distinct
preference for soybeans over corn.

Minnesota. A. G. Ruggles (July 19): Grasshoppers being reported from
all southern and western counties of the State. Not alarming, but
unless controlled will build up.

Missouri. L. Haseman (July 24): The infestation in Missouri continues
to be serious. Some second-brood emergence, apparently of Me-
lanoplus mexicanus Sauss.






-..269-


North Dakota. F. G. Butcher (July 19): Grasshoppers continue to be the
most important insects in all counties, except in the northeast
corner of the State, with M. mexicanus the predominant form. Most
of the important species are in the adult stage. Localized mi-
grations have been commonly reported during the last 2 weeks over
most of the infested area but the hoppers have not spread out ex-
tensively into noninfested areas. Control operations are slowing
domn considerably in some areas, since farmers are becoming dis-
couraged because of the continued invasion by adult flights. IA.
bivittatus Say, M. packardii Scudd., M. mexicanus, and M. femur-
rubrum Deg. have been observed mating and M. bivittatus has started
laying eggs.

South Dakota. H.. C. Severin (July 2): Many grasshoppers are now fully
winged. Considerable migration is taking place. Hordes of grass-
hoppers are moving into South Dakota from the south and many are
leaving the State for regions elsewhere. Owing to harvest, the
poisoning campaign has lagged. (July 3): M. mexicanus is the
species most harmful in South Dakota. Of considerable less im-
portance are M. differentialis arid M. bivittatus. A very serious
infestation covers r.ah of eastern South Dakota, cast of the
Missouri River. Much less serious west of the Missouri, but. become
more abundant near the Black Hills. Considerable damage has already
been done to small grain, corn, and garden crops.

Nebraska. 0. S. Bare (May 20 to July 20): Grasshoppers proved to be
the outstandingly major pest in. the State during the period here
covered. The grisshrpper infestation is unquestionably the heaviest
and most widespread since the pioneer "grasshopper years" of lg74-
76. Every county in the State has exporiencod serious crop damage,
with the possible exception of five or six counties in the sandhill
area, and more or less scattered but somewhat destructive ihfesta-
tions have occurred there. M. Mivittatus and M. mexicanus h.ad
hatched in large numbers by May 20, and hb.tching of those species
continued into the early part of June. M. differentialis had barely
started to hatch on May 20, but developed rapidly and continued well
through June. The first noticeable crop dan.-,-:e was reported about
MIay 20, and became increasingly heavy throughout the 2-month period.
Spring seedings of alfalfa and clovers wore badly da(m'ged or destrcyeO,
and spring-planted grains and older alfalfa and clover fields in many
sections were badly stripped. Serious damage to corn began carly in
June and has continued to the close of the period covered by this
report.

M. H. Swenk (July 20): Parasites of grasshoppers have begin to
arp~er in force. The amortwt of parasitization by the sarcophagid
fly Sarcophaga kellyi Aid. had by July 20 become quite large. Dead
M. bivittatus, M. differentialis, M. foenur-rubrum, ?.nd M. mexicanus,
collected from two faris near Lincoln fror June 25 to July 1, bean
giving up maggots of this species within 24 hours. Of the 691 grass-
hoppers collected on one farm, a total of 125 sarcor ,gid. n. -Cots






-270-


emerged and 103 pupated and successfully reached the adult-fly stage,
giving a total successful parasitization of 18 percent. Even heavier
parasitization has been reported from western N'br&ska, especially in
Garden County, where the toll of Sarcophaga kellyi on the grasshopper
p-pulation has become obvious on some farms. Parasitization of grass-
ho0ppers by S, kellyi was.first reported from Hall County on June 22.
A great abundance of the mite Eutrombidium trigonum has also developed
on Nebraska grasshoppers. The first reports of the presence of these
Smites in abundance came from Jefferson, Boone, and Dodge Counties on
June 25, 26, and 30, respectively, and reports have since become
general over the State. Since the end of June, and especially during
July, there have been .reports of heavy infestation of grasshoppers,
especially of M_. bivittatus and M. differentialis with hairworms
(Gordiacea). These have come from Richardson County north to
Douglas and Madison Counties and west to Furnas County.

Kansas. H. R. Bryson (July 22): Although grasshoppers are abundant in
nost sections of the State, the situation is not alarming and not
as bad as last year. In some localities parasitization is playing
an important role in- the natural control. The most common parasites
are the dipterous ones and the horsehair snake (Mermis sp.). In
northeastern Kansas 50 percent parasitization has been observed in
some localities, but the number of reports received by corrc-
spondence have been comparatively few. This is no doubt due to the
effective organized control campaigns that have been instituted in
the counties. Such campaigns are usually accompanied by the dis-
tribution of information that would ordinarily be sent out in
correspondence. Most of the species involved at present are Me-
lanoplus bivittatus, M. mexicanus, M. differentialis,'and M. femur-
rubrum. The lubber grasshopper Brachystola magna Gir, is more
abundant on the highlands north and around Manhattan that it has
been for several years.

Tennessee. G. 11. Bentley (July 21): The outbreak of M.' femur-rubrum and
M. differentialis in several counties has been satisfactorily
controlled. The nurserymen of Franklin County have reported that
the peach leaves on young growing stock were badly eaten by grass-
hoppers before they krnew of their presence.

L. B. Scott (July 16): Grasshoppers are still present in large
numbers, with the most noticeable damage in tobacco. Where no baits
have been applied the damage amounts to as much as 80 percent.

Arkansas. D. Isely (July 24): It has been estimated that 335,000 acres of
crop land had potentially injurious infestation of grasshoppers during
the latter part of June and the early part of July. The greater part
of this infestation .was M. differentialis. In some spots, however,
1M. mqxicanus was the dominant species, and its appearance was earlier
in June,. The most seriously injured area. was in the Delta between
the St. Francis and Mississippi Rivers,, in .northeastern-Arkansas, with
some heavy infestation in the counties immediately west of this. The





-271-


outbreak has been brought under control fairly well. In the north-
western part of the State, where injury was most severe in 1936,
grasshoppers have been less numerous than average, except in a few
spots. Where injury has occurred, the destructive species have been
M. differentialis and M. femur-rabrum. M. bivittatus, ordinarily
regarded as an unusual species in northwestern Arkansas, has been
abundant in a few spots.

Oklahoma. F. A. Fenton (July 20): Grasshoppers continued to be the most
injurious insect pest in Oklahoma during the past month. The most
common species, M. differentialis, has now largely reached the
adult stage and is prevalent in alfalfa and cotton fields. Most
:of the crops, with the possible exception of alfalfa, are beyond
the point where they can be injured by these insects.

C. F, Stiles (July 22): Grasshoppers continue to be very
numerous in Oklahoma, except in the extreme southeastern counties,
and in some localities there are outbreaks. Corn, cotton, and
alfalfa are suffering most at this time. Many cornfields are
being completely defoliated and the third cutting of alfalfa is
being seriously damaged, where the hoppers have not been poisoned.
The species doing the most damage are M. bivittatus, M. differen-
tialis, and M. mexicanus. The species most prevalent in the western
Panhandle counties is Dissosteira longipennis Thos.

Alabama. J. M. Robinson (July 21): In Jackson County grasshoppers were
reported on July 17 as being a very serious threat to field crops.
The bird grasshopper (Schistocerca americana Drury) is causing
serious concern at Deatsville attacking over 2 acres of cotton and
about 1 acre of oat stubble. Adults were emerging on July 19.

Mississippi. C. Lyle (July 23): Schistocerca americana Drury was damaging
corn and cotton at State College about the middle of July. It was
necessary to use poisoned bait to control them. Infestations of
grasshoppers have been found in Warren, Washington, and Quitman
Counties, attacking cotton and other crops.

Texas. F. L. Thomas (July 23): Grasshoppers were damaging wheat on June
26 and 27 in Hemphill and Ochiltree Counties. Fifty percent of the
wheat heads were on the ground at Canadian in Hemphill County and
also in Dallam and Sherman Counties, of the north Panhandle area.

Idaho. C. Wakeland (July 21): Small local outbreaks of grasshoppers are
being baited in Bear Lake, Bannock, and Caribou Counties, south-
eastern Idaho; in Fremont County, northeastern Idaho; in Lincoln
and Gooding Counties, south-central Idaho; and in Payette County,
southwestern Idaho. The population is increasing and we expect
outbreak conditions in larger areas in 1938.

Utah. G. F. Knowlton (July 29): Grasshopper conditions are becoming
increasingly serious as late-hatched nymphs increase in size.






-272.


Large populations are encountered in many localities in hnrthorn
Utah. Alfalfa is being seriously damaged at Liberty, Eden, and
Smithfield by grasshoppers, 9Sprcent of which are nymphs. More
of the grasshoppers are winged in central and southern Utah.
Pastures are being damaged at Dry Lake, Sardine Canyon, and Benson.
(July 19): Grasshopper damage is very severe to alfalfa in the
Nowton-Clarkston area. Damage is very severe in many parts of
Millard County.

Arizona. O. L. Barnes (June 28): First-instar nymphs of the second
generation of M. mexicanus were appearing generally in alfalfa
fields in the Blaisdell district, 12 miles east of Yuma, on June
18. Populations ranged from 1 to 5 per square yard. A few
nymphs wore in the second instar. First-generation females
were first noted on April 22 and were numerous by May 5. In
1936 first-instar nymphs of the second generation were first
taken. June 17.

MORMON CRICKET (Anabrus simplex Hald.)

North Dakota. F. G. Butcher (July 19): First actual reports of damage
by Mormon crickets in North Da kota wore obtained this month.
These insects are alarmingly numerous, especially in southern
Burleigh County, Emmons County, and in McKcnzie County. Some
crop injury has been reported in these areas.

South Dakota. H. C. Severin (July 3): A. simplex has increased
enormously in abundance in South Dakota this year. This is the
first time in history when complaints have reached us that
Mormon crickets are doing considerable damage in the State.
The Mormon crickets are found in large numbers, chiefly west
of the Missouri River, but they are numerous in the Roe Heights
Hills, as far east of the Missouri River as Hand County. (July
21): The Mormon cricket situation is becoming more serious,
especially in Butte and Lyman Counties.

Montana. H. B. Miller (July 22): Mormon crickets were laying eggs
in Powder River Countyon July 10.

Utah. C. J. Sorenson (July 21): Mormon crickets are very abundant
in Jumb and Tooele Cnunties. They are only moderately abundant
in Millard County, because of control work.

SUGAR 1EET WIREWORM (Limonius californicus Mann.)

California. R. E. Campbell (July 24): A letter just received says:
"Wireworm damage in Ventura County this year has been more
widespread and severe than :)ny of the oldest inhabitants can
recollect." Other reports indicate that at least three-fourths
of the bean fields show wireworm damae in- varying: cdgrees.





-273-


JAPANESE BEETLE' (Popillia japonica.Newm.)

Connecticut. W. E. Britton (July 23): More -prevrlent than ever before
in the southern half of Fairfield and New Haven Counties, and in
the Hartford and Now London areas. Th? he-.-viest infestations sr'm
to be in Bridgeport, Hartford,- New Haven, and Ridgefield. The
earliest emergence recorded was on June 22. Tzo lots of adults
from New Haven have been received for identification.

Rhode Island. A. E. Stene (July 23): The Japanese beetle, 'is 'showing
increase in present infested localities but so far as known. no
new localities have been discovered in which infestations arc
sufficiently heavy for people generally to discover them.

New York. E. P. Felt (July 23): P. japonica is more abundant than
heretofore in southeastern New7 York. In some localities- in-
festations approach outbreak proportions.

New Jersey. T. N. Dobbins (June): In the vicinity of Moorestown the
first adult beetle above ground was found on June l4, whereas
in 1936 the corresponding date wr;s June 7. Adults increased slowly,
probably as a result of the comparatively cool, cloudy weather, but
by the end of the month they were becoming abundant locally, espe-
cially in southwestern New Jersey, where feeding danmag-c became
evident by the close of the month. The normal, evenly distributed
rainfall of May and June provided ample soil moisture so that in
most sections the soil is in excellent condition for rapid emerg-
ence and oviposition with the advent of normal July weather.

Delaware. L. A. Stearns (July 23): Severe injury throughout the northern
portion of New Castle Cunty. Apparently about the peak in the
cycle of infestation by this insect.

Maryla.nd. E. N. Cory (July 26): Many reports and requests for informa-
tion being received from many parts of the State.

ASIATIC GARDEN BEETLE (Autoserica castanea Arrow)

Connecticut. W. E. Britton (July 23): This insect prevalent in certain
localities and caused dam-.;e. Seventy-five adults .were received
from a garden in Strnford. It is attacking various flowering and
vegetable plants.

THITE-FRINIGED 77EVIL (Naupactus leucoloma Boh.)

Florida. J. R. Watson (July 23):' N. leucolona apparently reached the
peack of its emergence in Walton and Okaloosa Counties between July
10 and 15. It was estimated that there were close to 500,000 beetles
per acre in some.of these fields., The beetles are actively laying
eggs. One of the most striking observations was that they are breeding
parthenogenetically. A. N. Tissot was the first to observe that no
males were to be found.







-274-


Florida and Alabama. H. C. Young (July 1): Known infested area, 35 square
miles--20 square miles in Walton and 13 in Okaloosa Counties, Fla.,
and 2 in Covington County, Ala. One-third of area is in cultivated
crops and remainder in cutover and woodland range. Host plants of the
larvae are corn, cotton, velvetbeans, sugarcane, peanut, sweet-potatoes,
parsley, cocklebur, carpetgrass, paspalum, cabbage, collard, amaranthus,
and a:i(ple trees. Adults attack cotton, corn, and peanuts.

Alabama. J. M. Robinson (July 14): Adults are emerging near Lockhart.

Mississippi. C. Lyle (August 10): Light infestation discovered at 'Laurel.

A WEEVIL (Calomycterus setarius Roelofs)

Connecticut. M. P. Zappe (July 22): Adults plentiful in Stratford, about
as many as last year. In old infestations at Sharon not so many adults
as last year, but adults plentiful at two new localities in the southern
part of town. Plants attacked are clover, sweet clover, Ampelopsis, and
Helenium. Some injury to garden peas in one place.

GREEN JUNE BEETLE (Cotinis nitida L.)

Virginia. A. M. Woodside (July 21): Green June beetles became very numerous
in codling moth bait pails at Staunton on July 6 and have continued so,
although their numbers are now decreasing.

C. R. Willey (July 10): These beetles were swarming about and
fertding on Chinese elms 4 miles east of Amelia and 5 miles southwest
of Amelia they were as bad on several medium-sized black oaks, feeding
on the tender new growth r mile away. On the same farm they were
swarming about several apple trees and several Wild Goose plums.-

GRAPE COLASPIS (Colaspis brunnea F.)

Virginia. C. R. Willey (July 13 to 17): This beetle quite numerous on,
crapemyrtle and Deutzia in nurseries around Norfolk. Doing consider-
able damage to some by chewing tender tips of new growth.

Georgia. T. L. Bissell (July 29): Adults feeding on the inside of bracts
surrounding cotton squares and bolls. Little damage apparent.

Arkansas. D. Isely (July 2h): Has caused some local injury by feeding on
the bracts of the cotton squares and on foliage in the northeastern
part of the State.

Alabama. J. M. Robinson (July 14): Actively feeding on cotton and soybeans
in Madison and Limestone Counties, adjoining Tennessee. Some years
ago this beetle was observed in the Tennessee Valley, affecting the
stands of cotton, corn, and soybeans, the larva





-275-


having fed on the roots of these plants. We also found that the
larvaz feeds on the roots of lespedeza, which is grown in a large
wy as a hay crop in the Tennessee Valley. Apparently these
insects are spreading into the cotton at this time.

CUTWORMS (Noctuidae)

Illinois and Wisconsin. N. F. Howard (July 1): Full-grown larvae of
Prodenia ornithogalli Guen. wore found in pea fields in Illinois
and Wisconsin, but were not numerous enough to cause noticeable
damage.
A
Nebraska. D. B. Whelan (July 22): Moths of the cotton cutworn (P.
ornithogalli) have recently been very numerous at lights at
Lincoln, reaching their peak about July 15-20, and indicating
a possible outbreak later in the season.

Mississippi. C. Lyle (July 23): D. W. Grimes collected specimens of
the yellow-striped armyworm (P. ornithogalli) at Durant on July
13. It was attacking cotton at Puckott on July 8.

Wisconsin. C. L. Fluke (July 20): Lycophotia margaritosa saucia Hbn.
is in very destructive numbers in southern Wisconsin, particularly
in Iowa, Grant, Lafayette, Green, Rock, Dane, Dodge, Columbia,
Fond du lac, and Manitowoc Counties. They emerged first in the
hnyfields and as soon as the ha-y was cut moved into adjoining
grain, corn, or potatoes. Have also caused trouble in the barns
around the milking machinery, many dyinr there and emittin,- con-
siderable odor.

Minnesota. A. G. Ruggles (July 19): L. margaritosa saucia is very
abundant. Reports coming from all over the State.

Nebraska. M. H. Swenk (July 22): A very severe outbreak of the varie-
gated cutworm occurred from June 8 to July 10. It did considerable
damage to alfalfa, corn, potatoes, many garden crops, flowers,
meadows, shrubs, and trees. These complaints were received from
many parts of the State.

South Dakota. H. C. Soverin (July 3): Cutwvorms of several species,
including the pale western cutworm (Porosagrotis ortho'onia Morr.),
have done an immense amount of damage in South Dakota this year.
In fact, this has been the most destructive cutworm year we ever
had in this State.

SUGAR BEET '7EBWORM (Loxostege sticticalis L.)

North Dakota. F. G. Butcher (July 19): Sugar beet webviwrms have caused
considerable alarm in various places, being particularly numhrus
in a weedy flax field in Grand Forks County a-d in potato, wheat,
and barley fields in Foster County.







-276-


Idaho. C. Wakeland (July 21): Local outbreaks of the beet webworm in
Latah and Benewah Counties, in northern Idaho. Lambsquarters
has been almost completely defoliated and larvae have attacked
peas, doing very heavy damage in small areas. The attack is much
worse along the margins of the fields, but some injury occurs
throughout the fields, owing to the presence of lambsquarters, on
which the spring brood evidently oviposited. The second generation
of moths began appearing July 13.

Colorado and Utah. 0. A. Hills (July 6): Outbreaks this year are un-
usually numerous, particularly in the Grand Valley of Colorado,
where this insect rarely becomes of economic importance. It has
been necessary this year to spray about 15 percent of the sugar
beets in western Colorado and eastern Utah.




GARDEN E3BW70RM (Loxostoge similalis Guen.)

Missouri. L. Haseman (July 24): DIuing the first half of the month
the garden webworrm did much damage to corn, alfalfa, and garden
crops in central Missouri.

Nebraska. D. B. Whelan (July 22): There have also been large flights
of the moths of the garden webworm at the light trap. Trouble
with this pest later in the season was indicated again on July
16-lg.

Texas. F. L. Thomas (July 23): L. similalis is causing more injury
than usual in central Texas in cotton and alfalfa in the Bell,
Hunt, and Limestone Counties from the middle to the last of June.

WHITE-LINED SPHINX (Sphinx lineata F.)

Michigan. R. Hutson (July 22): The white-lined sphinx moth is common
about Saint Johns and Lansing.

Wisconsin. C. L. Fluke (July 20): Extremely numerous in hay, potato,
and alfalfa fields. Feeding mostly on purslane but unconfirmed
reports on potatoes and sudan grass. Reported from.nearly every
county in south-central Wisconsin, running northeast from Lafayette
County to Brown.

Minnesota. A. G. Ruggles (July 19): Larvae sent in from two-thirds of
the counties of the State. So numerous that. farmers are alarmed,
but little damage thus far. Feeding mostly on purslane, then fire-
weed, then leafy spurge. Has been found feeding on lettuce and
carrots and did some d.Imnge in a field of potatoes.






-277-


South Dakota. H. C. Severin (July 23): The white-lined sphinx has
appeared in enormous numbers over the entire State. Consider-
able damage-is being done to garden and field crops, as well
as to shade trees.

Tennessee. L. B. Scott (July 22): Being taken in traps in large numbers
in Montgomery County. This species is at least twice as numerous
as in a normal year. No reports of damage by larvae have been
received.

Idaho. C. Wakeland (July 21): Larvae are very abundant in several*
localities of this State and are occasioning many inquiries.
Reports have been received from Fremont and Teton Counties of
eastern Idaho and from Latah, Nez Perce, and Benewah Countins
in northern Idaho. Larvae arc feeding almost exclusively on
dock and what is locally called tar-weed, only attacking other
crops after these weeds are defoliated, at which time the larvae
are practically mature; therefore little damage to economic crops
is caused.

EIGHT-SPOTTED FORESTER (Alypia octomaculata F.)

South Dakota. H. C. Severin (July 235): The eight-spotted forester has
been more abundant than usual and has done considerable damage to
grape, woodbine, and related plants.

Nebraska. M. H. Swenk (July 22): :'unirous reports of the presence of
larvae on wild or cultivated grapes and woodbine were received
from June 12 to July 15 from Sheridan, Lincoln, Howard, 'ucklls,
WTayne, Lancaster, and Douglas Counties.

CEREAL AND FORAGE-CROP INSE C TS

7iHEAT AND OTHER SMALL GRAINS

ARMYA0,RM (Cirphis unipuncta Haw.)

Connecticut. R. B. Fricr'n (July 20): Six acres of oats in New.ington
and about 5 acres of grass in an orchard in Farmington destroyed.
Caterpillars about fully grown. Also reported from Guil-ford,
where between 5 and 6 acres of grass and clover in an orchard
ancd 1 acre of sweet corn were infested. The sweet corn was
severely d-.aged. This insect has also been reported as feeding
on grass in an orchard in Hampton.

New York. N. Y. State Coll. Agr. News Letter (July 6): Armyworms showed
up in Niagara County this week, eating all the clover cover crop in
one orchard. (July 26): Armyworms have come to the front during the
past week in Chautauqua County. They are pretty well scattered over
the entire county, but are serious only in a few places on the Lake
Erie plain. The arnmyworms are heavily parasitized by braconids.









R. W. Leiby (July 19): Two local outbreaks on sudan grass and
alfalfa appeared from July 13 to 15 in Suffolk County.

Pennsylvania. H. P. Antoine (July 27): Infesting oats and corn; 50 acres
50 percent damaged in Newton Township, Lackawanna County. Attack
is localized,

Virginia. D. W. Jones (July 27): In Onley a few local cornfields are
practically ruined at this time by armyworms of the second genera-
tion. They are now about 3/4 inch long and have not yet begun to
migrate.

E. J. Udine (June 10): Damage heavy. In an infestation at
Timberville the tarley stems wore eaten ,ff just below the heads,.
allowing the heads to drop to the ground. Damage was greatest in
the low parts of the field.

Ohio. T. H. Parks (July 22): A flight of armyworm moths has been in
progress for the last 4 '7eeks. They have been caught in large
numbers in the codling moth bait pans, and at an electrocutor trap
light. The numbers caught have decreased greatly during 'the last
few days and the flight seems to be about over. Injury to ripening
cherries by the moths was received from Lorain, Sandusly, and
Franklin Counties. No complaints of outbreaks have been reported
to us during July. The chief injury caused by the June outbreak
was to young grass seeded in the wheatfields. This was destroyed
in many fields of southwestern Ohio.

Illinois. W. P. Flint (July 21): The armyworn outbreak, which occurred
during the last month has about run its course. There is still
some trouble in the extreme northern counties, where the arrmyworm
larvae are now about half grown. In this section of the State the
worms are less numerous than they were in central and northern
Illinois.

Michigan. R. Hutson (July 22): There is an outbreak of armyyworms in the
Saginaw Valley, in the east-central part of the State.

Wisconsin. C. L. Fluke (July 20): Outbreaks were just becoming apparent
on July 17. Reports from Dane, D'dge, Columbia, 7Tashington, and Fond
du Lac Counties are more numerous than usual.

Minnesota. A. G. Ruggles (July 19): Armyworm reports beginning to come in
from Clay County and some southern counties.

Iowa. C. J. Drake (July l4): The second generation of armyworms is doing
some damage in oatfields. The infestation seems to be quite wide-
spread in the northern half of the State.

North Dakota. J. A. Munro (July 20): Armyworms were present in most of the
oatfields examined in the Harwood, Argusville, Durbin, and Kindred








vicinities. The infestations were sFotted over Cass County. In one case
where the field of oats was being cut--Durbin--the worms were moving out
into an adjoining field of wheat. Reports, most of which were accompanied
by specimens, indicate that the distribution of the worms is much more
widespread than was the case in 1927. Reports have been received from
points in Richland, Cass' Traill, and-Sarrent Crunties. I noticed only
few tachinid flies in areas where the worms were prevalent.

Oklahoma. F. A. Fenton (July 20): The Calosoma beetle which was so prevalent
following the armyworm outbreak has been identified by the national l
Museum as Calosoma lugubre Lec. -

Montana. H. B. Mills (July 22): There is now a rather cti'tical outbreak of the
armyworm in Richland County.

Utah. G. F. Knowlton (July 5): Armyworms are damaging wheat in one field near
Roosevelt.

HESSIAN FLY (Phytophaga destructor Say)

Ohio. J. S. Houser (July 1937): The hessian fly is less abundant in Ohio than
it has been at any time since 1929. The average infestation of the 34
counties visited during the course of the annual wheatfield surv--ey was
found to be 4.4 percent. In 1936 the state-wide average was 12.4 percent.
Clermont County, in the southeastern part of the State, was more heavily
infested than any other. The average of the 10 fields examined was 15
percent. The lowest infestation in the State (2 percent) was found in
Tuscarawas County. In 1936 Butler County ranked highest in the State,
with an infestation of 50 percent, but this year the infestation there
was only 5.7 percent.

Minnesota. A. G. Ruggles (July 19): Hessian fly is scarce. One report re-
ceived from Winona County.

Missouri. L. Hasoman (July 24): Stubble infestation in northeastern aid south-
eastern Missouri is running as high as from 50 to 70 percent with;in some
cases as much as three-fourths of the flaxseeds showing- parasitization
in southeastern Missouri, according to recent observations by G. D. Jones.

WHAT STEM iMALGGOT (Meromyza americana Fitch)

Ohio. E. W. Mendenhall (July 2): The wheat straw maggots are quite bad in
wheatfields in western 9urnties--Miami, Champai.n, Auglaize, and others.

Kansas. H. R. Bryson (July 27): The wheat stem maggot is more abwundant this
year than it has been for several years, according to observations by R.
H. Painter.

CORN

CORN EAR WORM (Heliothis obsoleta F.)

Minnesota. A. G. Sc-.hhl (July 20): Corn ear worm is moderately abundant in
I JBRARY
STATF PLiANT BOARD


.279, -









Lake Crystal, Blue Earth County.

Iowa. E. V. Walter (July 14): Eggs and larvae are present on &4 percent of the
ears in one field of early corn in Van Buren County. Counts made in sweet
corn from July 12 to 15 showed 12 percent of the ears-infested at Charles
City and 16 percent. at Belmond, in northern Iowa; 40 percent infested at
Polk City, in central Iowa; and-0SO percent infested at Chariton, in
southern Iowa. Larvae, probably first brood in northern Iowa, were near-
ly full grown. In southern -Iowa mature larvae had left the ears, and
eggs presumably of the second generation constituted most of the infesta-
tion.

Missouri. L. Haseman (July 24): Corn ear worm has been very serious "in the
tassels of field corn and in early sweet corn ears. Worse for this
season of the year than usual. ..

Nebraska. M. H. Swenk (July 22): Our only complaint of the corn e'ar worm so
far this season was received on July 3 from Pamwnee County, where it was
working in popcorn.

Kansas. IH. R. Bryson (July 23): This pest is still causing considerable in-
jury to corn, particularly sweet corn.

STALK BOREtR (Papaipema nebris nitela Guen.)

Indiana. J. J. Davis (July 26): The common stalk borer was reported damaging
corn at Noblesville and Elwood the first few days of July. At Elkhart
it was reported damaging lilies on June 30. In all cases the specimens
submitted .yere rather small, being hardly more than one-fourth grown.

Minnesota. A. G. Ruggles (July 19): The stalk borer is moderately abundant.
A number of reports of injury to potatoes and corn.

Tennessee. G. M. Bentley (July 21): Reported as attacking cotton and corn
grown in proximity of weed patches. The report has just come from
Ripley, Lauderdale County, where there is a considerable ifnfestation in
weedy cotton.

EUROPEAN CORN BORER (Pyrausta nubilalis Hbn.)

Vermont. H. L. Bailey (July 26): Many adults about old cornfields'in Essex,
Chittenden County, northwestern Vermont, the last week in June and the
first week in July. Scattering of moths noted in the counlyon July 21.

Massachusetts. A. I. Bourne (July 23): The European corn borer is at least
normally abundant throughout the State. Here in the Connecticut Valley
it is proving to be much more conspicuous generally than it was last
year. We are beginning to note a considerable amount of damage from
corn borer in fields of potatoes. This particular type of damage is '
most conspicuous in southern Hamnpden County, in fields just above the
Connecticut State line. Early maturing sweet corn in many fields shows
from 90 to 90 percent of the stalks infested and the ears are heavily
infested.






-281-


Connecticut. N. Turo'r (July 21): Infesting sweet corn, the corn borer has
been unusually destructive locally and is much earlier than in 1936.
First-generation moths are present.

I1. P. Zapoe (July 22): Very abundant in southern New Haven County.
Ma.ny larvae have reached pupal stage. Attacking corn.

Indian:.. J. J. Davis (July 26): According to reports from A:.ur::, emerr;ence
of corn borer moths was the latest of any season on record in Indiana.
The first male adults were taken on June 23, nearly 2 weeks later than
in 1936. The first female was taken June 25 and the first eggs June 28,
Cool nights delayed oviposition; otherwise weather conditions have beenr-
ideal for borer increase.

A CORUSTALK BC= (Diatraca sp.)

Texas. 0. D. Deputy (July 1): Green corn offered for sale in the markets at
Brownsville seems to run about 25 percent danmged. The stem end of the
ear is most frequently attacked.

CHirCH BUG (Blissus leucopterus Say)

Ohio. T. H. Parks (July 22): Excessive rains through June and July have
completely eliminated the chinch bug as a problem for this season.

Indian-. J. J. Davis (July 26): The cool, wet weather has apparently checked
the development of chinch bugs. In Porter County, in the extreme north
end of the State, reports of conspicuous abundance were received on July
10. From Morgan County, in central Indiana, where chinch l'u.-s have not
been conspicuous for many years, came the report on July 15 that serge
was being badly attacked in spots. The bugs submitted were from second
instar to nearly mature. It is believed that these are the immediate
progeny of overwintering bugs. Reports from Greene County (between
Vincennes and Terre Haute) on July 20 indicate some trouble from the
first brood, these being sufficiently numerous to indicate probable
trouble from the next brood of 'buFs. The outbreaks are scattered and
slow in showing up, making control applications difficult.

Nebraska. M. H. Swenk (July 22): Chinch bugs did slight damage to corn in
lTcaiha County durin- the second week in July, but were not injurious
elsewhere in the State. No migrations were reported from elsewhere than
Nemaha County.

Oklahoma. F. A. Fenton (July 20): Damage has been reported from Vinita, Craig
County; Bixby, Tulsa County; and Haskell, Muskogee County, in north-
eastern Oklahoma.

C. F. Stiles (July 22): Chinch bugs are present in larger numbers
in Choctaw County, southeastern Oklahoma, than they have ever been,ac-
cording to reports from old settlers. Corn in. some fields has been
seriously damaged.





-292.


A CERCOPID (Lepyronia quadrangularis Say)

New York. R. W. Leiby (July 13): This angulate frog hopper migrated to a
field of corn from a freshly cut meadow and completely destroyed a
portion of the field. In another field, where corn was just up, a
third of a 15-acre field was destroyed. The injury took place during
a period of very hot weather in Fonda.

SOUTHERN CORN ROOT WORM (Diabrotica duodecimpunctata F.)

Ohio. T. H. Parks (July 22): A serious outbreak of the larvae was reported
in sweet corn during July. Reports came from Hamilton and Hocking
Counties, southern Ohio.

Indiana. J. J. Davis (July 26): The southern corn root worm has been re-
ceived as damaging corn from the northern half of the State, the first
reports coming from Frankfort and Remington, on July S and 12, re-
spectively. At Crown Point, corn following this springs planting
of sugar beets was damaged on July l4. At Connersville 90 percent
of commercial sweet corn acreage in one field was destroyed on July
19. Considerable damage also reported from Winamac, Pulaski County, on
July 21.

Missouri. L. Haseman (July 24): Serious throughout central Missouri. Beetles
emerging in great numbers.

CORN ROOT WORM (Diabrotica longicornis Say)

Kansas. H. R. Bryson (July 16): Reported causing injury to corn at Garnett.

CORN SILK BEETLES (Luperodes spj)

Mississippi. C. Lyle (July 23): The corn silk beetle was found attacking
roses at Kilmichael on June 25, and cotton at Laurel, Ripley, and
Decatur during the first week in July. It was also reported on cotton
and corn at Lake on July 7 and on cotton at Aberdeen on July 20.

Louisiana. B. A. Ostorberger and M. B. Christian (July): Found injuring corn
in Franklin Parish. About g0 percent of the silks completely destroyed;
very few grains of corn on ears. Also found injuring cotton.

CORN FLEA BEETLE (Chaetocnema -rPOlicaria Molsh.)

Indiana. E. V. Walter (July 20): The corn flea beetle is much more numerous
at this time of the year than it has been for the last 2 years at
Lafayette.

ALFALFA

ALFALFA WEEVIL (Hypera postica Gyll.)

Utah. J. C. Hamlin (June): Injury by the alfalfa weevil was light this season,









except in Millard County, Utah, and in Douglas County, Nevada, there
50 percent of the fields were severely dn-aLged. Scouting revealed the
weevil in five counties not heretofore known to be infested; namely,
Weston, Campbell, Sheridan, and Johnson in Wyoming, and Custer in South
Dakota.

California. A. E. Michelbacher (July 19): In the San Jcaquin Valley there 7as
a marked increase in the alfalfa weevil population. On July 4 the average
number of larvae collected per 100 sweeps of an insect net ran as high as
785. This increase is probably the result of a partial second genera-
tion. In the Pleasanton and San Francifco Bay areas the larval popula-
tion has remained small. On July 12 the average number of larvae collect-
ed to 100 sweeps in the most heavily infested field in the San Francisco
Bay area was ll4. In other fields larvae and adults have been difficult
to find. Parasitization by Bathyplectes curculionis Thos. h!,s dropped
very rapidly. On July 4 it was less than 1 percent in the San Joaquin
Valley, while in the cooler regions it was about 12 percent.

POTATO LEAFHOPPER (Emrapoasco fabae Harr.)

Virginia. F. W. Poos (July 20): More abundant on alfalfa this season than at
any time during the last 8 years. All cuttings are severely yellowed
and injured. The yellowing began to show up as early as June 8, although
this insect first appeared the night of May 5, only 2 days earlier than
in some other years.

Indiana. J. J. Davis (July 26): Alfalfa yellows, caused by the potato leaf-
hopper, has been unusually prevalent since July 15 throughout a large
portion of the southern half of the State and extending north, at least
as far as Lafayette. Also less conspicuous to the northern border of
the State.

A CLOVER SEED CHALCID (Bruchophagus sp.)

Oklahoma. C. F. Stiles (July 22): The clover seed chalcid is quite numerous
in the alfalfa-seed-producing area of Washita County.

THREE-CORVERED ALFALFA HOPPER (Stict~cephala festina Say)

Louisiana. L. 0. Ellisor (July): Is very abundant in fields of alfalfa in the
southern part of Louisiana. In some fields at least 75 percent of the
alfalfa plants are girdled.

COWPAS

COWPEA CURCULIO (ChalcX.,.rmus actneus Boh.)

Georgia. T. L. Bissell (July 23): The curculio is very destructive to cowpL07as
this year, unstung pods being hard to find. First-generation adults
appeared in cages on July 18.

Alabama. J. M. Robinson (July 21): Active on cowpeas in central nnd southern
Alabama.


-253-









VETCH

VETCH BRUCHID (Bruchus brachialis Fahraeus)

Pennsylvania. C. C. Hill (July 7): Heavy damage in Arendtsville by this post.

SUGARCANE

SUGARCANE BORER (Diatraea saccharalis P.)

Louisiana. A. L. Dugas (July): Infestation of the sugarcane moth borer is
generally light throughout the sugarcane area. A number of localized
areas present a rather heavy infestaKtion. The very abrupt decline in
egg deposition in the last 2 weeks has been accompanied by a heavy
natural parasitization of Trichograma. An unidentified larval parasite
was collected on July 26.

FRUIT INSECTS

SHOT-HOLE BORER (Scolytus rugulosus Ratz.)

Maryland. E., Cory (July 7): Found on Japanese weeping cherry at Pikesville.

Ohio. T. H. Parks (July 22): More than the usual number of complaints have
been received about this insect in peach, plum, and cherry.

Indiana. J. J. Davis (July 26):' Destructive to cherry at Hanm6nd on July 5 and
at Noblesville on July 10.

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

New York. R. E. Horsey (July): A couple of branches on glossy buckthorn at
Rochester were found to be infested with scale. Young moving scales
were noted here on July 20.

Georgia. 0. I. Snapp (July 13): Infestation has increased rapidly in a number
of peach orchards at Fort Valley, central Georgia.

COIMMON RED SPIDER (Tetranychus telarius L.)

Idaho. R. W7. Haegele (July 23): Within the last week or 10 days extremely
severe infestations of the two-spotted mite have appeared on apples and
prunes that were free of mites 2 weeks ago. Prune orchards sprayed 2
weeks ago for European red mite are now badly infested with the two-
spotted mite.

APPLE

CODLING MOTH (Carpocapsa pomonella L.)

Massachusetts.. A. I. Bourne (July 23): There are indications that the codling
moth is more abundant this year than for the last few seasons.








New York. D. W. Hamilton (July 24): First-brood adults began to emerge between
July 12 and 15, and daily bait-trap captures are still increasing. Band
captures were. still increasing on July 19. Peak flight'of first-brood
moths will probably occur about August 2. Most of the first-brood en-
trances occurred during the second and third weeks of June; consequently
there should not be as much late August and early September injury as
there was in 1936.

New Jersey. E. Kostal (July 12): First-generation infestation seems to be the
heaviest.since 1933.
Delaware. L. A. Stearns (July 23): Injury at close of first-brood attack less
than at any time since 1929, First first-brood moths emerged on July 2;
peak flights on July l4 and 17. First second-brood eggs deposited on
July 5 and first second-brood larvae emerged on July 9.

Virginia. A. M. Woodside (July 21): Adults of the first summer brood began to
emerge at Staunton on July 5. Emergence has apparently passed its peak.
Infestation is generally fairly light.
4
Georgia. C. H. Alden (July 21): Well-sprayed orchards at Cornelia have only a
light infestation, even the the weather has been dry and favorable for
codling moth development.

Ohio. T. H. Parks (July 22): The bait-pan catch of moths has been rather low
since June 23. No definite peak of second-brood moths has yet appeared,
nor is one expected. The frequent summer rains have apparently done much
to prevent many second-brood entrances.

Indiana. J. J. Davis (July 26): The first full-grown larvae left apples at
Orleans, in south-central Indiana, on June 16, 2 days earlier than in
1936 and 3 days earlier than in 1935. However, cool, wet weather slowed
up activity and the development of the second-brood worms is several days
later than normal.

L. F. Steiner (July 22): Activity of first-brood adults as indicated
by bait-trap captures, reached its peak in southwestern Indiana between
July 14 and 17, or approximately 1 week later than in 1936. Although
first-brood adults are only about half as abundant as the spring brood,
the present population is nearly as great as that of the first brood in
1936, which was far above normal. Weather conditions have been much less
favorable for'second-brood establishn;-nt this season. In one moderately
well-sprayed orchard first-brood worms averaged more than 25 per 100
apples, with additional sting injuries of 90 per 100.

Illinois. W. P. Flint (July 21): Second-bruod codling moth was. somewhat delayed
because of the cool weather during the first part of July. The hatch of
worms is now heavy over the entire southern half of the State.

Michigan. R. Hutson (July 22): The first adults of the second brood arc be-
ginning to appear at Buchanan, Monroe, Lapeer, Vandalia, and Allt-ga:.






.296.


Minnesota. A. G. Ruggles (July 19): Codling moth is moderately abundant.

Missouri. L. Haseman (July 24): Second-brood worms emerging all over the
State but they are being effectively controlled,

H. Baker (July 30): The first first-brood'moth was caught June
30 at Saint Joseph, in the northwestern part of the State. The first
big catch wvas on July 15 and the peak catch to date was 6n July 24.
Daiage by second-brood worms is at its peak it present and is heavier
than was anticipated. Abundance about average.

Nebraska. W. W. Darlington (July): Damage by the codling moth was identified
from as far west as Sheridan County in apples sent in the first week of
July. The survival of overwintering larvae at Lincoln was 67 percent,
as indicated by larvae gathered under bands and placed in racks in the
fall of 1936, and 57 percent of the overwintering larvae of the spring
brood had pupated by May 12,' when the initial 1937 observations were
iade. Pupation continued to June 24, although bulk pupation had oc-
curred by May 29. The first moth emerged on.May 22; peak of emergence,
May 29; the last moth of this brood emerged on July 3: 60 percent of
the spring-brood moths had emerged by May 29. In bait-trap catches at
Agricultural College orchard the first aid last moths were taken on
May 19 and June 25, respectively, with the peak of catches on May 25,
28, and 29. E;,- laying by moths of the spring brood began May 27 and
continued through July 3, the largest number of eggs laid on any 1 day
being on May 30. The earliest date onr. which first-brood larvae were
found under bands was June 19, the number collected increasing daily to
July 6. From July 7 to July 20 the number of larvae collected under
bandCs gradually decreased; a sufficient number was collected on the
latter date to indicate continuance of first-brood larvae for several
weeks. Pupation of first-brood larvae began June 20 and reached its
peak on July 6 and 10. First-brood moths began to emerge on July 3.
Peaks of emergence occurred on July 10, 12, 18, 20. Oviposition by
first-brood moths was first observed on July 11 and the greatest
number of eggs were laid on July 16. First-brood moths have been taken
in bait traps since July 11, with the largest single catch on July 16.

YELLOW-NECKED APPLE WORM (Datana ministry Drury)

Missouri. L. Hasemnan (July 24): Larvae were maturing on July 20 and are far
more abundant in central Missouri than for years.

LEAWHOPPERS (Cicadellidae)

Indiana. J. J. Davis (July 26): Leafhoppers were reported as serious on apple
at Valparaiso on June 23 and observations show them to be common and
destructive throughout the State.

Massachusetts. A. I. Bourne (July 23): The white apple leafhopper (Typhlocyba
pomaria McAteo) is most commonly encountered. This year our attention
has been called to an unusual abundance of the green potato leafhopper









(Empoasca fabae Harr.) and where it is abundant it has occurred at least
2 wveks later than the white apple leafhoppor; therefore, its control
offered further complications.

Connecticut. P. Garman (July 21): Potato leafhopper more abundant on apples
than for the last 10 years in.Hartford, New Haven County.

W. E. Britton (July 21): Specimens of Empoasca fabae Harr. on aprlo
have been received from Norfolk and Cannondale.

APPLE MAGGOT (Rhagoletis pomonella Walsh)

Maine. F. H. Lathrop (July 19): The first fly of the season emerged in a cage
at Monmouth, Kennobec County, on June 24. Emergence nearing the peak on
July 19.

Massachusetts. A. I. Bourne (July 23): Apple maggot emerging normally and seems
to be normally abundant.

Connecticut. P, GarmAn (July 21): Flies began to emerge this year much earlier
than usual in our cages nmd have beer. observed in fair numbers in certain
orchards.

New York. N. Y. St. Coll. Agr. News Letter (July 6): Apple mag':ot flies are
emerging steadily in the Hudson Valley from cages operated by entomolo-
gists of the Poughkeepsie staff. In general, it might be said that
emergence records and weather conditions indicate a favorable season
for the development of apple maggot.

June 22.

Missouri. L. Haseman (July 24): During the month the adult beetles have con-
tinued to be unusually a!un~.-.nt, with some evidence of tree infestation
,by the larvae. Some larvae practically full grown on July 24.

Kansas. H. R. Bryson (July 27): The flatheaded apple tree borer appeared from
Juno 20 to July 23. Because of the drought of the last four or five
seasons, trees have become weakened and this insect has caused and is
still causing considerable d u.b,;e to sha.' and fruit trees, as well as
to some shrubs. Reports of injury have beeoon received of this pest in-
juring 7;alut trees at Pittsburg and shade trees at Topeka, Arnold,
Olathe, Kansas City, and Leavenworth.

Oklahoma. F. A. Fenton (July 20): The flatheaded apple tree borer continues
to be possibly the most destructive tree borer in 01'.ahn.a. Reports of
borer damage have been received from Claremore, Roff, Chickasha, Roose-








volt, and Prague.


PACIFIC _LATHEADED BORER (Chrysobothris mali Horn)

Arizona. C. D. Lebert (July 22): Quite a number of shrubs iii lodal yards at
Phoenix have been severely injured or killed by this borer. Common
among the host plants are Pyracanth", rose, sycamore, willow, and poplar.
Infestations seem more numerous this season than usual.

APPLE SEED CHALCID (Syntomaspis druparum Boh.)

termined by jarring at Bridgeville, Su~sex County, was on July S. In-
jury will be light.

Virginia. A. M. Woodside (July 21): Some adults were collected in May at
Staunton; still alive in the insectary but feed very little and no
eggs have been found for over 2 weeks. All of the beetles from drops
have emerged, but none found to contain eggs and no eggs have been
found in the cages. Beetles feed greedily but do not mate.

Georgia. 0. I. Snapp (July 20): At Fort Valley the second-generation egg
deposition began on July 6, just before the Elberta peaches began to
ripen; therefore that variety wo.s subjected to a second-brood attack
this year. All other varieties of peaches escaped a second brood of
larvae. Forty-nine percent of the first-generation females had started
to deposit second-generation eggs by July 20. The infestation is lighter
than average.

Missouri. L. Haseman (July 24): This pest is seemingly greatly delayed in its
breeding. Some varieties of plums at Columbia show considerable numbers
of larvae from half to full grown.

infestation, as compared with 0.5 percent in 1936. This insect is in-
creasinc slightly over the upper middle and northern parts of the Peach
Belt, aetThomaston and Monticello.

Mississippi. C. Lyle (July 23): Peach twigs injured by this insect were re-
ceived from Columbia on July 16. M. L. Grimes, of Meridian, and D. W.
Grimes, of Durant, report injury to peach twigs in tl.'-ir districts.

TARNISHED PLANT BUG (Lygus pratensis L.)

out the Pecan Belt of the State, and has caused widespread defoliation
and stripping of pecan and walnut trees. This is the thii-d successive
season stripping has occurred. The first moths of the second genera-
tion have emerged. Reports of damagCe by first-generatibn moths have
come from lM'lskogec, Bristow, and Prague.

CITRUS RUST MITE (Phyllocoptes oleivorus Ashn.)

Florida. J. R. Uatson (July 23): Over a considerable portion of the Citrus
Belt, particularly in the northern part, the July rainfall was consider-
ably less than normal; therefore rust mites persisted longer than usual.

Louisiana. I. J. Becnel (July): Pc-. ,ro,,wcrs have complained of nrust mite in-
festations. Several growers in Plaquemnines Parish hv-wc dusted with sul-
phur, tr elininate the chances of damaged fruit.

well and the resulting larvae have finished feeding and have entered the
ground to pupate. Eggs are still being laid and considerable damage is
being done in certain sections by the larvae.

New York. N. Y. St. Coll. Agr. New Letter (June 29): Potato beetles are be-
ginning to appear and are doing some damage in Saratoga County, eastern
New York. Beetles and slugs appeared in small numbers during this week

Minnesota. K. A. Kirkpatrick (July 15): Farmers are commenting on the small
number of beetles this year, as compared to other years. Some large
growers report, that they have not hnd to spray for them. It is inter-
esting to note that the irrigated fields show the least presence of
larvae. Irrigation is overhead, and apparently the cool water dis-
courages these insects from doing damage.






-293-

Indiana. J. J. Davis (July 26): The corn ear worm has been an outstanding post
of tomatoes during the last month. The first report came on June 23 from
Gibson County, closely followed by.reports from other counties in the
southern half of the State. In some fields this first brood of worms
infested 80 percent of the fruits. The only reports of infestation in
corn cunme to us from JeffersonCounty on June 29 and from Spencer County
on June 30. Those infestations were earlier than usual, doubtless
because the mild winter permitted the insect to overwinter farther north
than normal, although observations indicate th-.t they did not winter as
far north as Orleans. Most of the worms have left tomatoes and are in
the pupal stage in the soil. No appreciable infestations were found in
Stomatoes.north of Indianapolis.

Illinois. W. P. Flint (July 21): L.,rvae much more abundant than usual over the
entire State. Severe injury has occurred to tomatoes and sweet corn in
southern Illinois. Some damage to tomatoes in greenhouses in northern
Illinois has been reported.

Kentucky. M. L. DiClrtke (July 24): Tomato fruit worms are doing considerable
damge at Lexington, Versailles, and Calhoun.

California. J. Wilcox (July 15): In southern California damage in several
fields of early tomatoes has increased with the advance of the season.

Salem and Geneva, in Utah County.

Nevada. G. G. Schwois (July 30): We have had two outbreaks of the tomato sphinx
moth (P. sexta) larvae on potato plants in July. Both of these outbreaks
were rather widespread, one being in Douglas County and one in Pershing
County. The Douglas County outbreak was controlled by ravens which ap-
peared in the infested fields in large numbers and got practically all
of the insects. In Pershing County it was necessary to resort to dusting
with calcium arsenate for effective control.





-295-


California. A. E. Michelbacher (July 19): The first brood of hornworms for the
most part are in the pupal stage. In places in the warmer interior

6 to 10 leaves on terminal growth of more vigorous varieties. In some
instances the smaller leaves have curled, dried, and dropped. (July 19):
In Orleans County hoppers are on the increase. (July 26): In Orange
County on black dirt there has been considerable injury from leafhoppers,
and quite a few fields of potatoes have died prematurely. (August 2):
In Suffolk Cr;unty leafhoppers and flea beetles have been responsible for
the early daath of Cobblers in many instances. Leafhop-'ers have been
particularly severe in the area about Huntington and East Northport.

Maryland. E. N. Cory (June 29): Leafhoppers are infesting potatoes at Easton.
Virginia. F. W. Pots (July 15): Infestation at Holland and Suffolk. Potatoes
were much more severely injured than usual. After the potatoes died these

joining potatoes are being severely injured. East of Suffolk, where more
potatoes were grown, the injury to peanuts is general.

Indiana. J. J. Davis (July 26): Abundant and destructive to potatoes -nd beans
throughout the State.

except for syrphid-fly larvae. While colonies were less numerous than
usual they were larger, therefore the migrating forms were probably as
numerous as usual. Dispersal from summer food plants is now going and
the infestation on potatoes is more general throughout Aroostook County
than that of the other three potato aphids.

HORNTWORMS (Frrtoparce sp.a.)

Florida. A. H. Madden (July 12): Larvae of P. sexta Johan. have been nch loss
abundant in Gadsden County than normal. Scarcity appears to be due to
the dry weather late in June and to the very efficient attacks of pre-
dacc-ous wasps, Polistes spp.

Tennessee. L. B. Scott (July 16): P. sexta and P. quinquemaculata Haw. are
causinz- moderate damage in Montgomery County. Continued dry weather
has delayed emerg-ence. The infestation is approximately normal.

IMacon, or possibly Perry, north and. east the infestation is heavy.






-30&-


About Tifton, in southern Georgia, it is not yet serious enough to be
doing any damage. The first new weevils emerged in the insectary at
Tifton early in the week. (July 24): Upland cotton in southern Georgia
has set a large crop of bolls, which are fairly well matured and past
ranger. Part of the Sea Island cotton failed to set early bolls, there-
fore most of it has a scarcity of well-grown bolls and is likely to suffer,

Florida. K. H. Smith (July 24): In Alachua County, northern Florida, square.
infestation in Sea Island fields under observation showed an average of
6.9 percent for the week ending July 3 and on July 24 an average of 27.5
percent.

Alabama. J. M. Robinson (July 21): Sufficiently abundant to warrant dusting
in several localities in central-south Alabama. The infestation at
Auburn is light,-as compared with previous years.

Mississippi. E. W. Dunnam (July 17): In the Delta section (Washington County)
boll weevils were increasing in infested areas very slowly, but spreading
farther from hibernation quarters. There was some dusting, -especially
on the late cotton, but the earlier cotton is too far advanced for in-
jury, and conditions on the whole are better than last season.

C. Lyle (July 25): The average infestation of the boll weevil for
the month of July has been around 8 percent, being mnch higher in a few
fields.

K. E. McCoy and J. Ragland (July 24): In Oktibbeha County, east
central Mississippi, the infestation was increasing very slowly, the
average being 5.7 percent, as compared with 4.4 percent on July 3. This
was higher than during the, same week in 1936 (1.93 percent) but very
much lower than for the same week in 1935 (41,2 percent) and in 1934
(50.2 percent).

Miss. Weekly Cotton Insect Rpt. (July 26): Weevils were found on
82 farms, with an average infestation of 101 percent, as compared with
10 percent last week, 4 percent on tlis date last year, and 30 percent
at the same time in 1935.

Louisiana. R. C. Gaines (July 3): Conditions during the last 2 weeks at
Tallulah, in Madison Parish (Delta section) have been unfavorable for
the rmultiplication of boll weevils. First generation weevils have been
emerging for a week or 10 days but, owing to unfavorable conditions,
the infestation has not increased as expected. (July 2)4): In some fields
cotton is fast reaching maturity. In field plots the infestation ranged
from 5,to32 percent, averaging 6 percent during the week.

C. 0, Eddy (July): Boll weevil has increased its activities during
the last half of the month, owing to rains.

3.4 to 25.8, with an average of l1.3 percent. In Choctaw County the
infestation is serious in the bottoms, but in the uplands comparatively
little d wi' le will be caused.

Texas, K. P. Ewing (July 3): Infestation in Calhoun County increased during
the week to an average of 23.12 percent, as compared to 10.7 percent
the preceding week. In the Lavaca River bottom at Edna there was an
average of 70.29 percent punctured squares. (July 24): Average in-
festation 70.49 percent. The maturity of the cotton combined with the
high weevil infestation in all of this area, particularly in C-Illi.un
and Jackson Counties, has caused the cotton to practically stop blooming
in many fields. There was a noticeable migration into snall cotton
this week.

Prog. Rpt. Tex. Agr. Expt.-Sta. (July 3): In general, boll weevils
are causing far more damage in the coastal prairie section north of
Corpus Christi than is realized. All cotton fields in the Lavaca River
bottoms of Jackson County are being severely rinagCcd where no control
measures have been used. (July 10): The boll weevil infestation is
increasing in southern and south-central Texas. (July 17): Average
infestation records from eight counties in the State, ranging from Van
Zandclt and Smith in northern Texas to Dimmit and Calhoun in southern
Texas, indicate that little damage is being caused in the northeast and
the blackland areas of central Texas. The infestation reached a maximum
of 40 percent on Brazos River bottom farms, and on upland farms the
average increased from 35 to 42 percent during the last week, according
to Bureau of Entomology and Plant Quarantine workers. (July 24): The
boll weevil infestation in untreated.fields of several counties averaged
as follows: Calhoun, 29 7ercent; Jackson, 53 percent; Brazes, 40 percent;

dar;ge is no so severe now as it was a few weeks ago.

E. T7. Dunnam (July 24): In Washington County, in the east-central
section, a few flea hoppers can be found but are causing very little
damage..

Louisiana. 'La. Agr. Expt. Sta. Bug News "(July 21): Abundant in the Red. River
Valley above Alexandria. New reports are now coming in on its activity
below Alexandria and in the Lafayette and Breaux Bridge districts.

R. C. Gaines (July 24): In the Delta section, in Madison Parish,
a few flean hoppers have been taken in the sweepings made each week, but
the numbers do not indicate much danmage to cotton.

B. A. Osterberger and M. B. Christian (July): Cotton flea hopper
seriously injurjihg: cotton in several parishes, mostly along Red River
from Natchitoches Parish to Avoyelles Parish.

Texas. K. P. Ewing (July 10): During the last 2 weeks there has been a marked
decrease in the flea hopper infestation in Calhoun County. (July 24):
In the young cotton flea hopper infestation continues sufficiently high
to cause nearly all squares to be blasted.

R. W. Moreland (July 17): In Brazos and Burleson Counties the in-
festations have been very light in upland cotton fields. On July 10
some dusting was being done in the bottom fields.
Tex. Agr. Expt. Sta. Prog. Rpt. (July 17): Plea hoppers are in
small numbers and causing practically no dnmn.ge, except in northern and
northwestern Texas. J. R. Quinby states that this insect is responsible
for the loss of 'from three to five snall squares each on 90 percent of
the plants of May-plan.ted cotton in Hardeman County. In Dickens County
the average infestation in 11 fields is 100 flea hoppers to 100 buds,
with a maximrun.m of 222. flea hoppers. (July 24): Flea hoppers have de-
creased in northern Texas but have increased on younz,: cotton in southern
Texas. They are reported as c0Using damage in Dnnley, Thoceler, Dickens,
and Hardeman Counties, northwestern Texas.

COTTON LEAF 1ORM (Alabama argillacca Hbn.)

Georgia. T7. L. Lowry (July 22): On July 22 one half-grown larva wr.s collected
on Sea Island cotton in Lowndes County. On July 24 one larva two-thirds
grown was found at Valdosta.

Florida. K. H. Smith and J. T. Roy (July 6): Pupae of the leaf worm were
collected on Sea Island cotton today near Alachua and McIntosh. As these
fields are some 45 miles distant, this indicates that the leaf worm may
be scattered over the northeastern part of the State. (July 19): In a
40-acre field near Alachua loaf worms were found in sufficient numbers
to be ragging the cotton in spots. As many as 25 worms were found on a






-311-


single plant, ranging from tiny threadlike worms a day or so old to


Florida. 7W. E. Conn (July 12): Light infestations in 2 acres of cultivated
cotton at Miami and some larvae now entering into pupal stage.

week.

K. P. Ewing (July 24): The infestation in Calhoun County in the
Gulf coast section is very spotted.

Tex. Agr. Expt. Sta. Prof. Rpt. (July 24): Leaf worms have been
reported in west-central Texas. Their ap'"earance near San Angelo, in
Tom Green County, is from 2 to 3 weeks earlier thin usual and may in-
dicate an earlier invasion of northwestern Texas. 7 *rms collected in
south-central Texas have been found to be heavily parasitized for this
time of year. (July 31): Have caused comparatively little injury to
date. They were found last week in Reeves County. The recent hot, dry
weather in central Texas tended to cause the newly matured moths to fly
a greater distance, even though uninfested cotton is near.

Arizona. W7. A. Stevenson (July 24): At Fresnal, Pima County, a very light
infestation was discovered on July 23. The first infestation in 1936
was found on August 12.

BOLL7ORM (Heliothis obsoleta F.)

Georgia. P. M. Gilmer and W. L. Lowry (July 24): From time to time a certain
amount of damage has been observed in many fields of cotton, but thus

an averagcof 9.9 c.-gs per 10C terminal's. At one point &'4 eggs per 100
terminals were counted.

Tex. Agr. Expt. Sta. Prog. Rpt. (July 24): E.- s have increased in
bottom-land fields and young worms are beginning to feed on the forms of

been poisoned showed a heavy aphid infestation.

Georgia. T. L. Bissell (July 20): Aphids are numerous at Experiment on the
growing points of cotton but do not seem to be harmful.

W. L. Lowry (July 24): With the advent of hot weather,' cotton
aphids seem to have disappeared almost entirely in Lowndes and Echols
Counties.

Mississippi. G. L. Bond (July 23): Several fields-of cotton at Moss Point
heavily infested with the cotton aphid during the last 10 days.

E. W. Dunnam (July 24): Aphid population increasing in one field
in Washington County.

Texas. K. P. Ewing (July 24): In Calhoun County aphids have caused practically
no damage in any of the dusted cotton.

TARNISHED PLANT BUG (gus pratensis L.)

Tennessee. D. M. Simpson (July 9): In 1935 we practically had a crop failure,
owing to damage from tarnished plant bugs. We have a heavy'infestation
of those insects again around Knoxville and a large percentage of the
plants are practically devoid of squares. The insects are abundant in
nearby fields of soybeans and lespedeza, also in weeds and grass. On
a recent visit to western Tennessee several farms were visited in Pay-
ette County near Somerville. On every farm damage similar to that at
Knoxville. was noted and tarnished plant bugs were found in the fields.

Louisiana. R..C. Gaines (July 24): Sweepings made in different cotton fields
in Madison Parish during the last few weeks have shown only small

where the corn silk beetle was reported causing severe injury to cotton
squares and young bolls on many farms.









FOREST AND SHADE.TREE INSECTS


GYPSY MOTH (orIetrta dispar L.)

Maine. J. V. Schaffner, Jr. (July 16): N. Irafton reports defoliation of
hundreds of acres of woodland in Kenneaec, Sagadahoc, and Lincoln
Counties. The infestation is the heaviest on record for these three
counties. Defoliation was spotty and local in the northern part of
York, southern Oxford, Androscoggin, and Cumberland Counties.

Portland Press Herald (June 29): Officials of the State depart-
ment of agriculture report the worst gyp&y moth scourge ever to sweep
southwestern and central Maine. Occurrence of the moths in devastat-
ing numbers is reported as far as Kennebec -nd Knox Counties, and in
less serious intensity eastward along the Ciastal counties to.'Washing-
ton County.

Massachusetts. J. V. Schaffner, Jr. (July 6): Thousands of acres of wood-
land in the eastern part of the State are completely defoliated. The
defoliation within 25 or 30 miles of Boston is more extensive than it
has been for many years.

A. I. Bourne (July 23): The defoliation this year was much more
general and widespread than in any recent year. There are beginning
to be many centers of rather serious defoliation just west of the
Connecticut River. Throughout central and eastern Masoachusetts are
similar large areas of very serious foliage strippings; however, in
the Cape district, from Buzzard's Bay to Provincetown, conditions are
apparently better than for several years.

Rhode Island. A. E. Stene (July 23): Probably the most outstanding note
regarding insect prevalence during the past month is the increase in
gypsy moth infestation. We have had large areas heavily infested
with this insect in the past, but there were a greater number of
places involved during the past season and the aggregate area where
defoliation has taken place is quite large.

Pennsylvania. A. F. Burgess (July 17): The interest of a former W.P.A.
worker resulted in the discovery of a larval infestation near the
Coolbaugh-Paradise Township line in Monroe County. This man, now
employed by the Delaware, Lackawanna, & Western Railroad Company,
observed an egg cluster qf the gypsy moth while working along the
railroad right-of-way and reported to the field supervisor in charge
of that district. Numerous larvae have since been discovered in a
rather restricted area. Intensive treatments will be applied in an
effort to -eradicate the infestation.

BROWN-TAIL MOTH (Nygmia phaeorrhooa Donov.)

Maine. N. Trafton (July 26): Only a few larvae were seen this season and
these were scattered through the towns of Bath, Hebron, PvRaymond,

Casco, Otisfield, and Paris.

SATIN MOTH (Stilpriotia salicis L.)

Maine. A. F. Burgess (June): Reports from the district inspector at Bangor
in June indicated that defoliation was pronounced throughout his dis-
trict. Shade and ornamental poplars showed the greatest injury.

N. Trafton (July 15): Se4Vere local outbreaks in most of the towns
in Androscoggin, Oumberland, Kennebec, Knox, Sagadahoc, Waldo, and York
Counties, and also sone in the southern parts of Franklin aid Oxford
Counties, and at Bangor, Brewer, Hermen, Oldtown, nd Orono in Penobscot
County.
New Hampshire. R. 0. Brown (July 21): Abundant in the vicinity of Conway
and Bartlett. Heavy feeding noticed on poplar shade trees.

OEEST T CAEBPILLAR (Mal cosoa dies trial Hbn.)

New England. A. F. Burgess (June): A very heavy infestation in New Hampshire
was reported by the district inspector at Keene. Complete defoliation of
oak, maple, and birch has been noted in several Vermont sections. Defolia-
tion of sugar maple orchards is reported as weakening the trees and
threatening next winter's maple sugar crop. Reports received from the
supervisory personnel in Vermont indicate that much damage is being done
in certain sections. Feeding is also noticeable in limited areas in
sections of Massachusetts and northwestern Connecticut.

Maine. N. Trafton (July 15): Many acres of woodland were severely defoliated
inlCumberland, Oxford, and York Counties.

Vermont. J. V. Schaffner, Jr. (July 23): In Addison, Bennington, Orange,
Rutland, Windhan, and Windsor Counties infestation was heavy. Thousands
of acres of mapleo sugar orchards and mixed hardwood forests were from 50
to 75 percent defoliated. The humid weather in the spring favored
epidemics of disease and large numbers of the caterpillars while in the
fifth and sixth instars succumbed to "wilt", thus reducing the infesta-
tion so that few trees were completely defoliated.

H. N. Bean (June 23): In Randolph, Royalton, and vicinities small
areas of maple and birch were defoliated. Large areas of defoliation in
town.

Minnesota. F. W. Forbes (June 20): Tent caterpillars reported very abundant
at Bemidji, Beltrani County. (June 21): Tentless caterpillars reported
moderately abundant at some points near the shore in Rosebush, Colvill,
and Hovland Townships, as observed by county agent. Reported by State
forest officers as very abundant at points on. Gunflint Trail, inland.

limited areas in sections of Massachusetts and northwestern Connecticut.

Maine. N. Trafton (July 26): Prevalent at this season. Many dhade trees
and apple orchards, also hundreds of acres of woodland were defoliated
this spring in the towns of Kennebunkport, Kennebunk, York, Wells,
Biddeford, Saco, Old Orchard, Scarboro, Cape Elizabeth, Portload, South
Portland, Westbrook, Falnouth, Cumberland, Y.-trnouth, Freoport, Bruns-
wick, Bath, Woolwich, Boothbay, rmid Bristol. Also one heavy infesta-
tion noted in Oldtown.

Nebraska. M. H. Swenk (July 22): One of the most injurious outbreaks of the
spring cankerworm (Paleacrita vernata Peck) in the history of the State
occurred between May 21 and June 23 and involved all of southeastern
Nebraska north to Douglas, Platte, Boone, and Custer Counties and west
to Dawson and Harland Counties, with separate isolated local outbreaks
in McPherson and Boyd Counties. Elm trees were the most severely
attacked, including both American and Chinese elm. Apple trees were
next most seriously attacked, and there wore a few reports of damage to
hackberry foliage.

OULY ELM APHID (Briosoma dhmericanum Riley)y

Nebraska. M. H. Swenk (July 22): Next to the spring cankerworm in serious-
ness on the elm trees, if not equally so, was an outbreak of the woolly
elm leaf aphid that began about May 27 and continued until June 28. This
outbreak covered most..of the -State, from the southeastern corner north and
west to Cedar, Holt, Dawes, Thomas, Perkins, and Redwillow Counties. Owing
Sto the two pests, the elm trees in Nebraska suffered heavy damage to their

thousand acres.

Minnesota.- A. G. Ruggles (July 19): Spruce budworm is moderately abundant.

Colorado. J-. A. Beal (June): A heavy infestation is occurring on ponderosa
pine hear Sugarloaf. An examination of the infested area showed the
larvae to be very abundant over at least a section of forested land.
On June 25 the larvae were tiny but had spun webs on nearly all the
pine buds in the area examined. In some instances two or three larvae
occupy a single bud. They are feeding on the needles and boring into
then at the bases. This budworm probably represents a different strain
than the one, found infesting Douglas fir on other parts of the Roosevelt
Forest. No sizable areas of infestation have previously occurred in
pure stands of ponderosa pine. The present one threatens to become
serious.

RED-HEADED PINE SAWFLY (Neodiprion lecontei Fitch)

Michigan. J. K. Kroeber (July 24): Sawfly larvae on jack and red pines now
more numerous than ever noticed before. About half grown. Will
probably result in killing one or more plantations on the Mackinac
State Forest.

A SCARABID (Pachystethus oblivia Horn)

Michigan. L. E. Yeager (June): An outbreak of the pine chafer beetle, which
has caused considerable alarm by its defoliation of jack pine on the
Manistee National Forest in Michigan, is much less severe this year.
This outbreak has been in progress since 1934 and, so far as known,
this is the first period when the insect has occurred in destructive
numbers. The beetles eat into the sides of the needles near the base,
cut off some needles, and cause others to die. This gives the affected
trees the appearance of having been scorched. Only the needles on the
current season's growth are eaten but, after 2 or 3 years of attack, the
trees begin to die in the tops, causing stag-head. Feeding tests with
larvae do not indicate that the larvae feed to any extent on the roots
of trees.

WHITE-PIITE 7EVIL (Pissodes strobi Peck)

New England and New York. E. P. Felt (July 23): Has been somewhat in-
jurious to leaders of white pine and also in spruce tips in southern
