INSECT PEST SURVEY BULLETIN
V0I.3 September 1,1923 No*6
OUT ST AID BIG ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR AUGUST ,1923-
In this number osf the Insect Pest Survey Bulletin statistics on the
summer Hessian fly surveys of New York State and Ohio are reviewed. The
situation is reported as generally favorable in the Ohio River Valley, while
the infestation in New York State is over 7 per cent higher than last year.
In North Dakota very heavy infestations were observed throughout Golden
Valley County, while in Nebraska this insect is present in the stubble in
below normal numbers.
The chinch bug situation in Ohio is very favorable, the pest being
very much less numerous than last year. Serious local damage occurred in
southern, central, and north-central Illinois, and a very serious movement
of the chinch bug was observed late in July in coutheastern South Dakota, vhile
both southeastern and northeastern portions of Nebraska are experiencing
rather heavy chinch bug damage.
The corn earwora, though not as serious as in 1921, is generally
prevalent over the eastern States. In the Ohio River Basin, especially in
southern Illinois and Indiana this pest has done quite serious damage to
tomatoes, while in Georgia this pest is doing even more damage to cotton than
the boll weevil in some of the northern counties.
The stalk borer is unusually prevalent throughout New England, the
Ohio River Basin, and the Upper Mississippi Valley, damaging a great variety
of plants, particularly corn and herbaceous flowers, dahlias and zinnias being
most seriously damaged.
The garden webworm continued throughout August to be a serious pest
to alfalfa in the Mississippi River Valley from Nebraska southward to Texas,
Midsummer reports on the cotton boll weevil are reviewed in this
number of the Bulletin. About 30 per cent of the total number of reports
received from the cotton belt indicate heavy damage by this pest.
The cotton leafworra appeared about two weeks earlier than usual
throughout the northern part of the cotton zone, while on the other hand the
cotton crop was about 10 days late in its development. Owing to these
conditions rather serious injury by the puncturing of the bolls is reported from
the greater part of the upper cotton zone.
The apple and thorn skeletonizer is appearing in a most unusual
epidemic throughout New England and southward to New York and New Jersey. In
New England it is reported as having skeletonized fruit trees to such an
extent that the damage is easily observable in passing along the railroads
or highways. It is reported about the middle of August for the first time
time in northern New Jersey.
The fall webworm is also occurring in unusual abundance throughout
New England and the Ohio River Valley,
«-21o«»
southward
The European red spider is now seriously abundan
to Maryland, ATest Virginia ^.nd westward to Ohio*
-217-
ndant throughout Mew England,
The Mexican bean beetle is reported from Adams, Highland, Pike and Scioto
Counties in Ohio and is substantially spreading in the previously infested States.
The Dagworm is generally serious throughout the Middle Atlantic, south-
eastern and Ohio River States, damage extending westward to Missouri.
OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA FOR AUGUST, 19 23.
Aphids generally are unusually numerous this year on all kinds of vege-
tation in Nova Scotia, and much apprehension is being shownv • on the part cf or-
chardists and growers with regard to the numbers of several species of economic
importance. The green apple aphid is more numerous in the Annapolis Valley than
it has oeen since 1913. The rosy aphid is likewise very numerous. The potato
aphid and the turnip aphid are very abundant, but a fungous disease induced by
warm, cloudy weather during the first two weeks of August checked their numbers
to a very considerable extent.
The red spider has seldom, if ever, been more injurious to small fruits
than it has been this year in the Niagara district of Ontario. Black currants
and raspberries are suffering particularly, the foliage turning brown, becoming
scorched, and the fruit crop in many instances be ins almost a complete failure.
The rose leafhopper, which occurred in outbreak form in apple orchards
in eastern Ontario early this season, has oeen reduced to insignificant proportions
through natural agencies . Parasitism has oeen very heavy.
The lesser migratory grasshopper continues in the ascendancy at many
points in Canada. The outoreak in the southern Okanagan Valley of British Columbia
is particularly severe and seems to be extending into more northerly points in the
same valley. In southern Aloerta and Saskatchewan the outbreak is continuing,
engendered to seme extent by migrations from certain points in northwestern United
States. In Prince Edward Island this species has for the second year in succession
caused a great deal of trouble in Kings and Queens Counties, covering an area of
approximately 100 square miles.
The clover-seed chalcid is proving to be more widely distributed in
southern Alberta than formerly. In some fields at leastlv/,0 per cent of the pods
contain larvae.
The fall webworm appears to be numerous everywhere in southern Manitoba
this year and also in the eastern townships of Quebec.
The spruce budworm is occurring abundantly in the neighborhood of Vic-
toria, B.C. A heavy outbreak is expected from this insect next year in this
locality and at other points in the coast sections.
The black walnut caterpillar has occurred in outbreak form in western
and southwestern parts of Ontario. Many walnut trees throughout this area have
oeen completely stripped of foliage.
A syrphid, close to Eumerus s trig at us Fallem , has been reared from the
roots of iris infested with the iris borer from Toronto, Ont . In all probability
this insect is European in origin.

Texas
GRASSHOPPERS ( Acridiidae)
R. L. TTebster (August 3): County agents report damage in Pierce,
Mercer, and I.'cHenry Counties.
M. H. Swenk (August 1-15): Grasshoppers, mostly Melanoplus
bivittatus r began to be complained of in Furnas and surrounding
counties early in August. There have been complaints of grass-
hopper injury in other parts of western and central Nebraska, but
on the whole these insects are less injurious than usual this year.
If. C. Tanquary (July 23): Reports of grasshopper injury continue
to come in from several counties of western Texas.
WHITE GRUBS (Phvllonhaga spp.)
Massachusetts A. I. Bourne (August 23): Numerous complaints have come to this
office relative to unusual abundance of white grubs from srery many
points throughout the State. Franklin, from East Wareham, finds
grubs "working in grass land in astonishing numbers. In one area
of about two acres, they had eaten off all the roots of the errass
so that the turf could be rolled back easily like a carpet, expos-
ing the grubs in such numbers that they cculd have been gathered by
the bushel." Complaints of these insects practically killing
large areas in lawns have been received from several of our corres-
pondents. One writes: "The grass in spots has died altogether,
looking as if it had been burnt by the sun. Flocks of robins and
other birds have been seen picking at the spots as if seeking grubs
or worms. The layer of turf is loose from the layer of earth just
beneath it. Running the hand between the turf and the earth will
separate the turf as readily as if one ran the hand between two
sheets" .
I owa
Massachusetts
F. A. Fenton (July 28): The June beetle, as predicted, has appeared
in swarms in southeastern Iowa in the counties bordering the Mississ-
ippi, where they have defoliated large tracts of woodlands.
WIREWOBMS (Elateridae)
A. I. Bourne (July 25): Wireworms are occasionally causing con-
siderable injury, although there is no general or widespread out-
break. Doubtless the injury is somewhat aggravated in most fields
by the protracted drought, which has weakened the plants so that
they have not been able to revive after early injuries by these
insects .

WHEAT
HESSIAN FLY (Phytophaga destructor Say)
New York C. R. Crosby: Owing to unpreventable conditions, it was necessary
to restrict the Hessian fly survey this year to eight counties in
the western part of the State. These indicate that the average
infestation for this region was 8.5 per cent compared with an in-
festation in 1922 of 1.2 per cent (see Vol. 2, page 195) and 5.2
per cent in 1921 (see Vol. 1, page 182). The infestation, by
counties, is as follows:
Genesee
Wyoming
Monroe
Livingston -
5.33 •
Wayne
-
18.35
1.60

-
21.89

H. A. Gossard (July 25): The annual wheat survey was carried into
298 wheat fields, distributed over 32 counties. Hessian fly was
found to be well under control in all counties except in a few in
northeastern Ohio, where considerable early seeding was made last
year. There is a distinct increase in infestation in Ashland,
Lorain, Summit, Portage, Columbiana, and Wayne Counties. In the
northwestern counties, where the county agents carried on an educa-
tional campaign, the infestation has been reduced to a very low
figure by observing the proper seeding dates. Henry County reduced
its infestation from 40 per cent in 1922 to 2 per cent in 1923,
Sandusky County from 52 per cent to 7 per cent, and Putnam County
from 39 per cent to 5 per cent. Wood County in this northwestern
section had one field sowed too early, with 94 per cent of the straws
infested and most of them lodged. Fulton County had one field
sowed September 7, with 82 per cent of the straws infested, and
another seeded too early had 46 per cent infestation. The reduction
over northwestern Ohio, therefore, was due to observing the proper
seeding dates and not to parasitism or natural factors. The State
average of Hessian fly infestation is 4.4 per cent, compared with
10.9 per cent in 1922".
C. N. Ainslie (July 27): Every field in Golden Valley County ex-
amined was heavily infested in June just as wheat was jointing, and
a brood of flies has since attacked the grain again. The limit of
attack is unknown at present.
M. K. Swenk (August l) : The Hessian fly is now present in the
wheat stubble in supernormal numbers. During July the infestation
was traced in the Platte Valley west to Dawson County, it being
present, in fact, in Furnas, Gosper, and Dawson Counties in greater
numbers, on the whole, than in the counties intervening between
them and the principal area of heavy infestation, which includes
Cass, Otoe, Nemaha, Richardson, Johnson, and Pawnee Counties.

-220-
WHEAT-SHEATH GALL J0INT70RM (Harmolita vaginicola Doane)
Ohio H. A. Gossard (July 25): The wheat-sheath worm is considerably
more numerous in eastern Ohio and will reach from 5 to 10 per cent
in some fields that were seeded quite late.
WHEAT-HEAD ARMYTtORM (Heliophila albilinea Hubn.)
Iowa C. J, Drake (July 27): The wheat-head armyworm has appeared in
considerable numbers in timothy fields near Ainsworth. In one
field the timothy heads were practically all destroyed by this
insect.
WESTERN 17HEAT SA7FLY (Cephus cinctus Nort.)
North R. L. Webster (August 3): The Burke County agent reports that in-
Dakota f est at ion running as high as 80 per cent has been found in this
county. (August 13): Severe damage was reported from Burke,
V/ard, Bottineau, and Towner Counties.
GREAT PLAINS FALSE VTLW^OTQ' (Eleodes opaca Say)
Nebraska M. K. Swenk (August l): The beetles of this wireworm have not
appeared in as large numbers as were expected from the amount of
serious injury done to the winter wheat in the southwestern part
of the State last fall and spring. This indicates a probable re-
duction in the amount of injury that will be done to the wheat crop
to be seeded this fall in that part of the State.
Texas M. C. Tanquary (July 23): A correspondent from Carson County re-
ported in early June that he had had 300 acres of wheat destroyed
by this insect.
ENGLISH GRAIN APHID (Macros iphum granarium Kby.)
Nebraska I.I. H. Swenk (August l): Following the unusual abundance of the
English grain aphid on wheat in southeastern Nebraska from June 18
to about the first of July, a local outbreak of the same insect
occurred in the western part, in Cheyenne County, about the middle
of July, but it was not nearly so extended or intense as was the
earlier infestation in the southeastern part of the State.
CORN
CHINCH BUG (Blissus leucopterus Say)
Ohio H. A. Gossard (July 25): Chinch bugs were found to be present in
rather limited numbers , being greatly reduced below their numbers
one year ago. We have had very few inquiries about them, and
while they could be found in limited numbers in most of the western
and northern counties during the wheat survey, they were not suffi-
ciently numerous to threaten corn anywhere.
-221-
Indiana J.J. Davis (August 22): Eggs of the chinch bug were abundant at
Monticeilo on" August 7. Very few eggs of the second generation had
hatched at that time. This is representative of the central section
of this State.
Illinois W. P. Flint (July 26): Rains caused a great variation in the number
of chinch bugs throughout the State. Serious local damage was done
in southern, central, and north-central Illinois. In many cases
from 1 to 10 acres of corn adjoining wheat was killed at harvest
time where no barriers were used. At the present time indications
are that the second brood will be very abundant.
Iowa F. D. Butcher (July 24): One farmer in Page County reported seeing
a few chinch bugs in his oat field.
F. A. Fenton (July 28): The chinch bug is present in injurious
numbers in the southeastern part of the State. The present dis-
tribution of this pest is greater than that of last year, showing
that it is on the increase in this State.
Missouri F. D. Butcher (July 24): The county agent at Maryvilie reports
that chinch bugs are injuring corn about 7 miles south of the Iowa
line.
A. C. Burrill (August 25): Chinch bugs have been reported as serious
from the following counties: Andrew, Buchanan, Caldwell, Clay, Davies ,
DeKalb,' Gentry, Ray, Adair, Chariton, Macon, Livingston, Pike, Ralls,
Bates, Boone, Maries, Miller, Morgan, and Lincoln.
South C. N. Ainslie (July 27): The bugs are moving by the millions into
Dakota corn during July in Charles Mix County, and although the farmers are
doing much to check them, much damage will doubtless be done. They
were reported as far north as Mitchell and also from Gregory County.
A number of adjacent counties are infested.
Nebraska M. K. Swenk (August l) : The chinch bug has been destructively abund-
ant during July in three separated areas_ of the State. One of these
areas, in the southeastern part of the State, includes Richardson,
Pawnee, Gage, and eastern Jefferson Counties, and extends northward
into southern Nemaha and southern Lancaster Counties. The centers
of injury in this area are around Humboldt, Auburn, Table Rock,
Pawnee City, V/ymore, Adams, and Firth. There is also some local
injury in Saline County. A second area lies in south-central Neb-
raska and includes Franklin arri Harlan Counties, around Riverton,
Alma, and Huntley, with some local injury in Gosper County. The
third area is in the northeastern part and includes eastern Keyapaha,
all of Boyd, northeastern Holt, and western Knox Counties. The
bugs began leaving the small grain for the corn in the first area
about July 4, a few days later in the second area, and about July
12 in the third area. The migration had practically ended in the
first two areas by July 25, out was still in progress in the third
area at the end of the month. OSh the whole, the chinch bug has
done more injury to corn in Nebraska this month than at any time
since the summer of 1910. Weather conditions continue favorable
-222-
for these pests, and if their present numoers arc augmented nor-
mally by the second generation during August, very menacing numbers
of chinch bugs will go into hibernation in these infested areas this
fall. (August 1-15): The chinch bug continued to do injury to
corn in the second area of infestation during the first' week in
August in diminished intensity, extending nest into Furnas and
north into Dawson Counties. By August 10 the second brood develop-
ing in the corn was under way.
CORN EAEWOEM (Keliothis obsoleta Fab.)
Haine E. M, Patch (August l) : The county agent from Freedom writes:
"This pest has quite a foothold in this town."
New York C. R. Crosby (July IS): A correspondent from Middletown says:
"This grub is raising h with my corn."
rrest W. E. Rumsey (August 15): Early sweet corn at Morgantown shows at
Virginia least 10 per cent of the ears attacked.
Ohio H. A. Gossard (August 20) : *7e had an inquiry from Cleveland July
26 for control measures for this pest, also from Brunswick August 1,
and from Lakewood August 15. This insect is injurious this season
over southern Ohio, though not so damaging as it was in the summer
of 1921.
New Mexico W. E. Emery (August l) : This insect in Dona Ana County is vf=ry
abundant and is doing considerable damage to the ear corn. In
the northern part of the county where corn is tasseling about 20
per cent of the tassels have been destroyed.
STALK BORER (Papaioema rite la Guen.)
"Ten
Maine E. Iff, Patch (July 21): A report from South Portland says:
per cent or more of my tomato plants are riddled by them. Lately
I found them working in the potato tops." (July 30) : I found
about 50 in potatoes and some in sweet corn. (July 3l): A report
has oeen received from North Haven. (August 2): fl report has
been received from Richmond.
Massachusetts A. I. Bourne (August 23): The potato or corn stalk borer is prac-
tically through its work for the present season. The larvae are
nearly mature and beginning to leave the plant. This insect has
apparently been unusually abundant this year. Many more complaints
have been received than normally from all sections of the State.
As I may possibly have stated before, this may be in some measure
due to the fact that interest is awakened in all borers in corn
from the publicity given the European species, but from our personal
observation this species was much more abundant this year than nor-
mally.
-22>
Rhode Island
Connecticut
Ohio
A. E. Stene (August IS): Another insect that is rather common
this year is the common stalk borer. We are getting specimens
of this almost every day with the inquiry as to whether it is the
European corn borer. It is apparently fairly abundant and attacks
of it are recorded on corn, potatoes, and peppers.
A. G. Davis (July 19): A report has been received from Torrington
of this insect attacking field and sweet corn. It is usually not
noticed. The crop is damaged to the extent of 1 per cent.
W. E. Britton (August 21) : This insect has been reported from
Waterbury, Somers, riamden, and Stratford as attacking corn, tomato,
and pepper. It is rather more abundant than in an average year.
H. A. Gossard (July 25):
all over the State.
The common stalk borer was received from
Indiana
Illinois
Iowa
Missouri
Nebraska
Nebraska
J. J. Davis (August 22): Most of the reports received the last
month are of nearly mature larvae in large corn stalks, where they
are doing little damage.
W. P. Flint (July 26) : The common corn stalk borer has been sent
in from many localities from small grain, corn, and ornamental
plants .
F. A. Fenton (July 28): The stalk borer has caused more damage
to various plants this year than it has for the past five years.
Several corn fields have been ruined, and in others the pest has
been present in the cuter rows. It is also reported in oats and
such ornamental plants as cosmos ana dahlia, and also has done
some injury to tomatoes.
L. Kaseman (July): This pest was very abundant and destructive a
little earlier, and many complaints about it were answered,
M. H. Swenk (August l) : During the second week in July there was
some injury to small grains and corn by the common stalk borer.
The amount of damage done by this insect was not very great, however,
ARirywOBM (Cirphis unipuncta Haw.)
M. H. Swenk (August 1-15): During the first week in August the
true armyworm appeared in Holt and Scottsbluff Counties, doing
considerable local damage in late oat fields. The armyworm out-
break, however, was not at all general.
California
ALFALFA /ND CLOVER
ALFALFA WEEVIL (Phvtonomus posticus Gyll.)
California Weekly News Letter, Vol. 5, No. 15 (July 28): An
investigation conducted by the State Department of Agriculture
has revealed the fact that the alfalfa weevil exists in one field
in Sierra County adjoining the Nevada State line. The infestation
is the result of the natural spread of the weevil from the alfalfa
fields in the vicinity of Verdi, Nev. Fortunately, the alfalfa
weevil still remains on the east side of the Sierra Nevadas, and
the same natural "barriers which acted as a measure of protection
when the weevil was confined to Nevada are effective, even in the
face of the infestation in Sierra County.
Calif ornia Weekly News Letter, Vol. 5, No. 16 (August ll) : In 10
days at inspection stations on the California-Nevada line, main-
tained by the California Department of Agriculture, there were
taken from 12 automobiles 126 live alfalfa weevils.
FALL AHAfYWOOT (Laphygma fruginerda S. & A.)
Florida F. S. Chamberlin (August 10) : Report of injury to young corn has
been received from Quincy. The crop was badly damaged.
GARDEN WEB WORM (Loxostege similalis Guen.)
Iowa C. J. Drake (July 27): The garden webworm has appeared in consider-
able numbers during the past week. At Melbourne and Woodbine it
has been reported as destroying fields of alfalfa. At Knoxville
and Woodbine some patches of sweet corn and parts of corn fields have
been severely injured. Most of the caterpillars are rather large
and almost mature at this time.
Since writing the above, a letter from Audubon, dated July 26,
states that the garden webworm practically destroyed a 40-acre field
of alfalfa in less than a week. I have just received another letter
from the county agent of Pottawattamie County, stating that a large
portion of the second crop of alfalfa in that county has been des-
troyed.
Nebraska M. H, Swenk (August l) : During the two weeks from July 13 to July
26 many fields of alfalfa in eastern Nebraska were badly damaged by
this pest. The worms, as usual, spun the tops of the plants with
webbing and ate the leaves. The injury was confined to the part
of the State lying east of the 99th meridian, and seemed to be quite
general over this area. Reports of injury were especially common
from Richardson, Pawnee, Gage, Jefferson, Thayer, Buffalo, Merrick,
Platte, Sarpy, Douglas, Washington, Burt, and Dakota Counties. Only
the second crop of hay was affected, especially those fields that
were not cut until about the first of July. (August 1-15): Injury
in alfalfa by the second brood of the garden webworm continued with
reduced intensity during the first 10 days of August. Before the
last of the reports of injury of the second brood were received from
northern Nebraska, great swarms of moths had appeared in southern
Nebraska, and are still flying at the present writing, indicating
the probability of continued injury by the third brood of the web-
worm late in August and early in September.
„
-225-
Kaaaas, J. R. Horton (August 6): Since July 23 or somewhat earlier
Oklahoma, Texas, webworms have been relatively scarce; injury has practically
and New Mexico ceased and the second brood of moths is on the wing. A very
heavy flight of moths was noticed all the way from Reno and
Sedgwick Counties, Kans . , to and including northeastern New
Mexico and the Oklahoma and Texas Panhandles. It looks as
though alfalfa and other forage crops and truck gardens might
suffer another severe attack by this insect.
Texas M, C. Tanquary (July): Curing the latter part of June and the
first of July there were reports of serious infestations of this
insect on cotton from Lamar, Panola, and other East Texas counties
EUROPEAN CORN BORER (Pvrausta nubilalis Hu$bn.)
Massachusetts A. I. Bourne (August 23): The European corn borer, from present
indications, would seem to be having a year of practically normal
abundance and about average injury, although it has been reported
that the area of severe injury occurring is somewhat larger than
last year, as would be expected. It is rather early, though, to
make any definite prophecy relative to this second brood.
Ohio H. A. Gossard (July 25): First and second instar larvae of the
European corn borer have recently been found in Lake County.
Moths had issued in the laboratory at Geneva a day or two before
June 29 but had not commenced laying eggs at that time. (August
20): Most of the moths of the European corn borer brood have
emerged in most of northern Ohio and at the present time eggs
are found upon the corn blades and the larvae are found in the
corn stalks and, under some circumstances, in weeds- where corn
is not available. Notwithstanding a thorough burning campaign
and clean-up in Ashtabula County last spring, there is an in-
creased number of borers this season, clearly indicating that
there were rcore moths in this area the present season than were
there last year. Since most of the corn stalks were destroyed
in the clean-up, it seems possible, and perhaps probable, that
a good many caterpillars are carried over the winter hidden in
weeds, and a need for the prompt destruction of corn stalks as
soon as the ears are removed is emphasized by this development.
SUGAR-CANE BORER (Diatraea saccharalis Fab.)
New Mexico R. Middlebrook (July 20) : The species Diatraea saccharalis and
D« zeacolella have been reported from the eastern counties of
the State. They are getting worse each year. The crop is
damaged 30 per cent.
A STALK BORER (Diatraea lineolata Walk.)
Hew Mexico J. R. Horton (August l) : Corn damage, estimated by counting 100
stalks in each field, covering most of Quay County, varies from
no stalks tunneled at all in some fields to as high as 85 per
hundred in others. Tunneled stalks contained from 1 to 6 borers
each. This injury is all by the first summer brood of borers.
-22 6-
About 1 to 2 per cent of stalks of milo is damaged in some fields -
as hightas 10 per cent in first two or three rmsirrdering infested
corn, in one field.
CLOVER ROOT-BORER (Hylastinus obscurus Harsh.)
Ohio K. A. Gossard (August 20): The clover root-borer was received from
Strongsviile August 6, where it had destroyed a field of clover.
I also received the saire insect two or three days ago from a Wayne
County field, where it had reduced the crop to less than one-half.
Indiana J. J. Davis (August 22): Injury has been reported from Connersville
in Fayette County.
CLOVER.£lEAF WEEVIL (Hypera punctata Fab.)
Ohio T. K. Parks (August 21): This beetle was sent by the Erie County
agent August 14, with the statement that the insect is working on
sweet clover. He saw one sweet clover field that had been pastured
pretty closely by the insect. It is unusual in Ohio for the oeetles
of this species to cause such damage at this time of year.
CLOVER- ROOT CURCULIO fSitona hispidulus Fab . )
Indiana J. J. Davis (August 22): Injury to roots of alfalfa reported from
Hartford City, in Blackford County.
Illinois VT. P. Flint (July 26): Sitcnes (sp?) has caused serious damage to
the roots, of old stands of alfalfa in central Illinois.
CLOVER-SEED CATERPILLAR (Laspeyresia inters tine tana Clem.)
Iowa C.J. Drake (July 2U): The clover-seed caterpillar has been re-
ported in Washington County. It seems to be numerous in several
fields.
W-MARKED CUTWORM (Noctua clandestina Harris)
Illinois W. P, Flint (July 26): This insect has been reported from several
sections in northern Illinois as destructive to sweet clover where
this plant is grown for seed crop. Parasites are fairly abundant.
MISCELLANEOUS
COTTONY GRASS SCALE (Eriopeltis festucae Fonsc.)
New York C. R. Crosby (July 16): Grass infested with this pest mas received
from Graves ville .
A SWEAT-BEE (Halictus vires cens Fab.)
Indiana G. M. Stirrett (July 19): This pest was reported injuring lawns
in LaFayette July 8 by throwing up little mounds of earth.
ARGUS TORTOISE-BEETLE (Chelyroospha. cassidea Fab.)
New York C. R« Crosby (July 23): This insect is doing considerable damage
to oats in Chautauqua County.

FRUIT INSECTS
APPLE
GREEN APPLE APHID (Aphis pomi DeG. )
A. I« Bourne (August 23): Green aphids have not heen
unusually abundant over the State as a whole this season
but Mr, Cobb, of Littleton, reports that in his orchards,
particularly on young trees, they have been exceptionally
bad, and apparEntly badly checked the growth in the
young orchards.
G. E. Smith (August 11): Growers are still applying the
later summer application for the green aphid. A few
are using lime-nicotine dust. The females continue to
keep the terminals infected with the young aphids.
F« EU Bond (August U): The lice have appeared on apple
in serious numbers in some orchards at Oswego.
H* W„ Fitch (August h) : They are very numerous at Sodus
on apple. (August 11): They ave very abundant on Mcintosh,
Greening, and 3aldwin at Sodus. A special treatment of
lime-nicotine dust gave very good control in one orchard
R« G« Palmer (August 11): Green aphids are present in
many orchards, and some are making special applications
for their control in Monroe County.
A. L. Pierstotff (August 11): The green aphid is reinfesting
the apple seedlings and they are still abundant on Spiraea
vanhoutti, at Honegp© Falls.
ROSY APPLE APHID (Anuraphis roseus Baker)
H* A* Gossard (July 25): Aphids of many species have been
active and conspicuous. The rosy apple aphid attracted
attention from many quarters of the State.
H. F. Dietz (July 18): The rosy apple aphid was unusually
bad this year and damaged between 15 and 25 per cent of the

CODLING MOTH (Carpocapsa nomonella L.)
Massachusetts A» It Bourne (July 25): So far as reports have come in from
the different sections of the State, injury from the codling
moth to date has been very light indeed. The emergence
of the moths of the spring brood was observed to be very

irregular, owing probably to the continued cold weather
prevailing during this period of the season. This has
resulted in a considerable amount of "side worm" injury,
which is slightly larger than is normally the case.
G. E. Smith (August 11): The larvae continue to hatch.
There is probably more or less of an overlapping of the
broods at this time in Orleans County*
R, G. Palmer (August 11): Codling moths are causing severe
injury on apples in Monroe County,
R. F. Illig (August 11): In some parts of Wayne County
there has been considerable side worm injury.
F* H. Bond (August 11): The larvae have just started to
emerge from the fruit in Oswego County.
H. W, Eitch (August 11): First-brood larvae continue to
enter the fruit on the shore of Lake Ontario. No second-
brood larvae that could be identified as such have been
found at Sodus,
B, A, Porter (August 6): Second brood larvae began leaving
the fruit between August 3 and 6 at Vincennes.
APPLE AMD THORN SKEEETONIZER (Henerophiln pjori*na ,Cl-g£ck)
Ax I* Bourne (August 23): Thhoughout the western part of the
State, at least, the pest of outstanding importance at present
is the apple and thorn skeletonizer.
E* K* Hollister (July 20): Reports have come from Hartford
and vicinity. This is practically the first appearance.
Fifty per cent of the foliage is damaged.
Chas. Dt Clark (July 2U): This is the second brood of this
pest and it is found generally throughout Fairfield County.
Many leases contain from 3 to 6 latvae. It is more abundant
than last year.
W. E» Britton (August 21): This pest is less abundant in
the southwestern portion of the State but is more abundant
in the eastern part.
A, E. Stene (August 12): The apple and thorn skeletonizer
has been sent in from Anthony and has been observed by our
field men in various places in Providence and Kent Counties,
from the Connecticut line to points three-fourths of the
distance across the State.
\
-229-
New York E, F» Felt (July 23): This pest is generally prevalent north
to Bandy Lake in the Hudson River Valley, even on widely
isolated apple trees in infested areas. Injury is serious
north to Claverack and Ravena and probably farther north,
M. D* Leonard (August 12): Badly infested leaves were
received from Roy Latham at Orient, Lc I,, who states that
this pest is unusually bad this season. (August 13): P.M.
Eastman of the New York Department of Farms and Markets
at Cambridge, near Eagle Bridge, reports it abundant on the
outskirts of town.
New Jersey M* D. Leonard (August 22): On August 13 I found about 5
per cent of the foliage injured "by the apple and thorn
skeletonizer in a small apple orchard of abov.t 50 trees at
Pompton. This is about S miles northwest of Paterson. Last
year these trees were under my close observation during the
entire growing season and there was no evidence of the pest
at that time, as far as I know this is the first record for
this State.
TENT CATERPILLAR (Malacosoroa americana Fab.)
Massachusetts A. I. 3o"urne (July 25): The first eggs of the apple tent
caterpillar were seen in Amherst on July 3» Since that -
time they have been found in considerable abundance.
New York Clark Hutchinson (July 21): At Cgder.sburg, in St. Lawrence
County, most of the caterpillars seemed to be in bushes at
first, but later some got into apple trees, though they do
not seem to ha^e increased in numbers large enough to do
any great amount of damage. I have noticed some farmers
spraying their orchards.
New Jersey R. B„ Lott (August 5) '• Fgg masses of apple-tree tent cater-
pillar have been noticed throughout State. They are quite
plentiful.
FALL WEBWQRM (Pyphantria cunea Drury)
Massachusetts A, I. Bourne (August 23): In Amherst and immediate region it
is at least no more abundant than it was last year, if quite
as much. From Middlesex County, E. R. Farrar reports that
in his estimation the pest is approximately 50 Per cent
as abundant as lait year,
Connecticut M. P, Zappe (August 22): Inf estationsooccur on ash, cherry,
apple, etc., in Hartford, TJindham, and New London Counties.
The webworms are more plentiful than they were last month.
New York Roy Latham (August 6): This species is bad this season. It
is on apple, maple, elm, cherry, and other cultivated trees
at Orient, Suffolk County.

several localities in Wayne County*
E. W. Mendenhall (August 22): We find them bad in old neglected
orchards and in a variety of nut and shade trees in southwestern
Ohio* They ar.3 noticeable along roadsides.
H. F. Dietz (July IS): The fall webworm is unusually abundant
in cities and towns, feeding on shade trees and ornamental
shrubbery. In the rural districts it does not seem to be
quite as abundant as in cities and towns.
J. J* Davis (August 22) : This pest is abundant wherever I
have been in the southern half of the State. It is abundant
in cities and along roadsides, also in orchards whihh ha^e
not been properly sprayed.
M. H* Swenk (August 1): The first brood of the fall webworm
was less numerous and destructive than it has been during
the last few years.
TARNISHED PLANT-BUG- (L?/gus prat ens is L»)
M« P» Zappe (August l): This pest is causing serious injury
to apple and peach stock in nurseries, and is also working on the
tips of dahlias, at Durham, Willimantic, and Hamden. It
seems to be doing more injury than in the average year.
A«» I* Pioratorff (August 11): At Honep^e Falls this pest is
common on practically all young trees and shrubs in a nursery.
LEAFHOPPERS (Jassidae)
Um D, Leonard and F» H, Lathrop (August 17): Many leaves of
young growth were very severely curled on a tree about 15
feet high as a result of the feeding on nymphs at Kinderhook.
A number of other trees in an orchard were appi-eciably affected,
but this one was the worst example we have ever seen.
A. L« Pierstorff (August 11): Leafhoppers are abundant on
one-year-old nursery trees at Honepye Falls. Instead of making
the characteristic mottled injury, they seem to curl the apple
leaves much the same as aphids, but not quite so severely.

SAtJ JOSE SCALE (Aspidiotus perniciosus Comst.)
A. I* Bourne (July 25): In ijorthern Worcester County Mr.
Fiske reports that he is finding the San Jose scale somewhat
more prevalent than last year. This, while the only
specific report coming to our attention this month, "bears
out the general impression among the fruit growers which
has "been held for some time that this pest is gradually
coming "back into abundance in the State.
H. A. G-ossard (July 25): The San Jose scale has practically
disappeared from some neighborhoods where it was rather
numerous in southern Ohio when spring opened. On this
account some tests of the comparative efficiency of scale
remedies are rendered practically worthless "because there
is no scale on the check trees and no difference can he
found in the various treatments. Of course, there may he
later developments which will have some significance.
Some unsprayed trees in northern Ohio have an ahundance
of San Jose. (August 20): San Jose scale was received from
Shiloh August 2. Specimens of apple were quite spotted over
by it.
B. A. Porter (August 20) : Second-brood crawlers began to
appear July 20 at Vincennes, on apple, peach, etc. Since
August 1 crawlers have been produced in large numbers
daily. In orchards where poor control was obtained last
winter, branches are beginning to die, and the fruit is
badly spotted,
J* J. Davis (August 22): T7ith the new lubricating oils,
as well as miscible oils, orchardists are making headway
against the scale. There still remain, however, many
serious infestations, but -most of the orchardists are
alive to the situation ar.a will stress dormant oil spraying
the coming season. Until lasjr year the scale was not
recognized as a serious pest on peach, but this year several
peach orchards have become alarmingly infested.
W. P# PlinU (July 26): 2?he season thus far has been very
favorable to the increase of this insect and it is showing
in large numbers on fruit, branches, and leaves of poorly
sprayed orchards.
EUROPEAN RED MITE (Paratetranychus pilosus C. & P.)
A. I. Bourne (August 23): The European red mite is
apparently normally abundant generally, with occasional
regions of slightly greater abundance. The protracted dry
spell which persisted up to the early and middle part of the
month was very favofable to their rapid increase, and from
some sections of the State estimates of these mites being
much more abundant, up to twice as many as last year, have
been sant in. A rather curious fact in connection with
this pest is that on a block of trees which had "been given
kw
-232-
a dust treatment, the mites were apparently much more
ahundant than on adjoining "blocks which had "been sprayed.
Connecticut Eb.il ip Carman (August 1-23): Baldwins show considerable
"burning at Branford ard Wallingf ord. This pest is more
abundant than last year. A dry summer has favored development,
Maryland C. C. Hamilton (August 25): Rains the past three weeks have
put the pest well under control, except at Havre de Grace.
Here there have "been only a few light showers, and the mites
are abundant and still doing damage. Indications are that
there will be severe injury tomfruit buds on peaches. Cool
nights and damp weather the last of July caused the mite
to migrate to the limbs and lay winter eggs there. These
have hatched. Infestations occur at Havre de Grace, Easton,
Berlin, and College,
West Virginia W. E» Rumsey (August 15) : Apple, maple, box, and other
plants are seriously affected, and have been since early
spring, by an undetermined red spider at Morgantown.
Ohio H. A, Gossard (July 25): The European red mitQ .has ...
appeared very numerously in northern Ohio and is known to
be present in great numbers in orchards as far east as
Youngstown and as far west as Toledo. It is causing severe
bt owning of the leaves of apple, plum, and peach. Members
of our staff have given it personal attention at Youngstown,
in the peach orchards about Danbury, and in pJum and apple
orchards at Waterville. It was reported very numerous on
specimens of apple leaves sent in from Toledo July 12.
G, A. Runner (August ll): This insect is abundant on many
fruit trees and ornamentals in the vicinity of Sandusky,
Insprayed grapevines have been observed which were heavily
infested, but injury to foliage seemed slight compated to
injury to foliage of peach and apple. It is also abundant
in many apple orchards in counties bordering on Lake Erie.
Eoliage injury is severe in orchards in which lime-sulphur
has not been used in summer sprays.
APPLE FLEA-WEEVIL (Orchestes pallicornis Say)
West Virginia W, E* Rumsey: (The locality given in ;-the Insect Pest Survey
Bulletin Vol. 3> Page 126, should be Raymond City instead
of Morgantown. )
Michigan R. H. Pettit (July 10): I have to report that our single
case of apple flea-weevil seems to be a very difficult one
indeed to control. Repeated sprays of powdered arsenate
of lead at the rate of l4 to 2 pounds to 50 gallons of
water are reported to have failed thus far. The insect is
spreading in spite of the sprays. Samples sent in show
the leaves to have been badly eaten after these sprays were
put on.

TCILLOw CURCULIO ( Crypt or hynchus lapathi I. )
R. H» Pettit (August 9): Testerday we discovered some apples
that had holes eaten in them and in the course of an hour:
or two we found that Crypt or hynchus lapathi was the culprit.
Today a gentleman from Lansing "brought in a number of plums
with similar holes eaten in them and a specimen of Crypt or hynchus
that he had actually caught in the act. He said a large
proportion of his ripening plums were "blemished in this
way. The injury amounts to more than a "blemish, however,
since in the case of the plum "brown rot immediately shows the
work of the "beetle*
A LEAF-BEETLE (Metachroma inter ruptum Say)
J* J. Davis (August 22): Injury to apples "by an unknown
insect was first reported "by Dr. B. A. Porter, who found,
on July 13, considerable injury to the fruit of Grimes
trees. The surface ds more or less covered with gouged -
out places, often these being confluent so that eaten areas
up to considerable size might be found on an apple. The
insects responsible were not found. When Porter showed this
infestation to me, a couple of weeks later, no additional
injury had been done, although the total injury to Grimes
fruit in this orchard was considerable. Specimens were
submitted to W. P. Flint, who had reported similar injury
by Metachroma interruptum Say, in western Illinois a year
ago and he pronounced it as certainly the work of that
beetle. According to Blatchley, it was collected but once
in Indiana, namely in Vigo County, in the west-central part
of the State, June l6. He also notes that it had not,
previously to his record in Indiana, been recorded east of
Kansas. This beetle is one which may become an important
pest. The orchard where first found at Decker, Knox County,
had been thoroughly sprayed according to the recommended
spray schedule.
PEAR

PEAR FSYLLA (Psylla pgricela Foerst.)
Philip Garman (August 20): This' pest is sevErely injuring
a large pear orchard at Southington.
E, W« Pierce (August 4): Hard-shell nymphs and flies of the
second brood are appearing in considerable numbers in
Ontario County. (August 11 ) : The dry weather has caused
psylla to multiply rather rapidly.
G. E. Smith (August k) : The weather has been very favorable
for pear psylla development, and considerable honeydew covers
fruit and foliage in some orchards in Orleans County.
-P3^-
H, W« Fitch (August *$) : This pest io abundant enough to
cause many grovzers at Sodus to spray.
F. H„ Bond (August h)i At Oswego the psylla has become had
in some orchards. (August 11): The psylla outbreak seems to
have subsided.
IU J. Palmer (August 11): The psylla in Monroe County has
multiplied rapidly.
P. J» Chapman (August 11): In Genesee County the pear psylla
is on the increase with favorable weather for its development,
but commercial orchards have them fairly well controlled.
PEiS SLUG (Csliroa cerasi L. )
Ohio H. A. Gossard (July 25): The pear slug was received from Apple
Creek July ik on pear, (August 20): This pest was received
from Columbus August 17 on pear,
Indiana B» A. Porter (July 27): Several acres of cherry orchards
have been completely defoliated by the second-brood slugs at
Vincennes.
Nebraska M* H. Swenk (August 1): Numerous complaints of injury by "it he
pear slug have been received during the month.
PEACH
PEACH-TWIG MOTH (Anarsia lineatella Zell. )
Indiana H. P. Dietz (July 18) : The peach-twig borer is becoming
quite a serious pest in young peaches in the southern part of
the State,
Texas F« C* Bishopp (August 25): This insect has caused some damage
to peaches in the vicinity of Dallas this year, but their
abundance is not nearly so great as during last season, when
over 75 per cent of the peaches were infested.
California California Weekly News Letter, Vol. 5, No. 15 (July 28): The
season of 1923 has not been marked by serious damage from the
peach-twig borer and there has not been as much damage to
unsprayed orchards as to some sprayed orchards last year. We
have no difficulty in controlling the pest With lime-sulphur
spray and expect to continue spraying with I .'.m-?- -sulphur in
the spring, as in the past, since under conditions at Ontario
such treatment insures against severe damage from either
"curl leaf" or twig-borer.

SHOT-HOLE BORER Ucolytus rugulosus Ratz. )
Henry Dietrich (July): The shot-hole "borer is fairly injurious
in peach orchards at Applet on.
H* A* Gossard (July 25): Specimens of this pest came from
Sullivan June 25 where it was attacking cherry, from Toledo,
June 27, and from Marion July 20, (August 20): Specimens
came from Marion August 3 on cherry and August 13 from
Pleasant Hill on plum. An inquiry without specimens was
received from Danbury July 2h regarding control measures for
this species.
PLUM CURCULIO (Conotrachelus nenuphar Hbst.)
0. I. Snapp (August 20): The second generation will he very
small this year and of little economic importance. The second
generation did not put in its appearance this year in the
Georgia Peach Belt until the peach crop had been harvested.
About S,600 cars of peaches were shipped from Georgia this
season, and the general quality of the fruit was the "best since
1918. The curculio has been remarkahly well controlled,
A "TUMBLE BUG"(Phanaeus carnifex L.')
W. E* Emery (August 1): This insect is doing considerable
damage to ripening fruit, in some places at least 50 per cent
to peaches and plums, and was also noted on the corn, working
on the tassel, where at least 10 per cent of the corn tassels
were destroyed in Dona Ana County.
• GREEN SOLDIER-BUG (Nezara hilaris Say)
C. C. Hamilton (August 22): Determination was made by comparing
injury with that reported in Ohio (Bui. 310 on the green soldier-
hug). The variety Hale is injured worst, although all varieties
are attacked. Injury ranges from severely deformed fruit to
that with only a few feeding punctures. Infestations occur at
Belair and Havre de Grace.
H. A. Gossard (August 20): The green soldier-hug was taken in
a Wooster locality August 18 injuring peach, An inquiry was
received from Port Clinton July 23, regarding an outbreak of
this pest on peach, and a later investigation by one of the
members of our staff proved that a rather mild outbreak was
occurring in a few orchards.
G. A* Runner (August 11); Injury to peaches by the green
soldier -bug has been observed in several orchards in the Ottawa
County peach district.

SAN JOSE SCALE (Aspidiotus perniciosus Corast. )
Georgia 0. I, Snapp (August 20) : At Eort Valley the San Jose scale
has increased rapidly during the summer months. Some growers,
dissatisfied with the results from liquid lime-sulphur or
its substitutes, will use lubricating -oil emulsion this
winter*
ORIENTAL PEACH MOTH (laspeyresia molesta Busck}

BEACK CHERRY APHID (Myzus corasi Fab. )
A* A» Granovsky (August 18): Cherry aphid attacks cherry
orchards year after year in the locality of Sturgeon Bay. Injury
is largely done in a local ifeed spot- Injury may be considered
as severe, producing yellowing and defoliation of trees, as
well as reducing the growth of terminal shoots and, consequently,
the yield of cherries. Early cherries were more infested
than late varieties.
PEAR AND CHERRY SAWFLY (Caliroa cerasi L. ) .
J, J* Davis (August 22): The work of this insect, resulting
in complete defoliation, is evident throughout the southern
part of the State.
CHERRY FRUIT FLY (Rhagoletis cingulata Loew)
Henry Dietrich (July): There is a considerable amount of
infestation this season at Applet on.
H* W» Fitch (August k) : One tree examined at Sodus showed
32 per cent of the fruit infested.
PLUM
PLUM CURCULIO (Conotrachelus nenuphar Hbst.)
Massachusetts A*. I* Bourne (July 25): The plum curculio seems to be doing
a great amount of injury this year, and in every section of
the State reports of normal or somewhat greater abundance
than last year are coming in. This particular species seems
to be at the present time the outstanding apple pest of the
State, and to all appearances is the one farthest from
control.

was received literally plastered with adult scales of this
insect. This scale insect had been a very serious pest on
these raspberries.
CRANBERRY
SPOTTED CUTWORM (Agrotis c-nigrum L. )
A. I» Bourne (August 23): The spotted cutworm has done more
injury on the cranberry bogs than in any previous year. We
find that this insect is most likely to attack bogs that are
bared of their winter flowage very late in May or in early
June. It has cleaned up the crop of more than 150 acres
of bog here this season, reducing the prospective crop by fully
10,000 barrels.

CRAPE
ROSS CHAFER (Macrodactylus subspinosus Fab.)
A* I. Bourne (July 25): The rose chafer has been unusually
abundant the present season, practically throughout the
State, and las not only caused considerable annoyance by its
feeding on roses and grapes, which it normally feeds on every
year, but complaints have been received of its injuries to
a wide range of food plants, which comprise many of the ,
small fruits, ornamentals, and,, garden crops, as well as some
few reports of its feeding on the foliage of young fruit
trees.

New York M» D. Leonard (July 27): This pest is abundant on bayberry
and several other plants outside of Jamica, L.I., near a
pond,
F. J. Whaley (August 4): There were several had infestations
on grape and rose in private gardens during the first week in
August at Albany.
Ohio H. A, Gossard (July 25): The rose bug was perhaps more numerous
than usual.
GRAPE LEAFHOPPER (Erythroneura comes Say)
New York K. E. Paine (August 10): In Chautauqua County on unsprayed
or on poorly sprayed vineyards the leafhopper injury is
showing very badly and wherever a grower missed a row in spraying
a marked difference can be seen.
West Virginia W. E. Rumsey (August 15): Foliage is completely destroyed in
some cases and generally seriously injured at Morgantown.
Ohio H» A. Gossard (August 20): The grape leafhopper was received
from Toledo August 15 on grape and also from Columbus August 17*
EIGHT-SPOTTED FORESTER (Alypia octomaculata Fab.)
Ohio H. A» Gossard (July 25): The eight-spotted forester came from
Windham July 6, where it was attacking grape.
Indiana H. F. Dietz (July 18): The eight-spotted forester has been
reported as a serious pest of grapes this year, especially
in the vicinity of Indianapolis and Muncie. This is the first
time in the past five years that we have had any reports of
damage by this pest.
GRAPE-BERRY MOTH (Polychrosis viteana Clem. )
Louisiana I, H# Jones (July l6) : Larvae and injured fruit have been
sent in by Mr, M» J, Voorhies, County Agent of St. Martin

canes. She also reports the larvae unusually abundant in
corn this year in her section.
PECAN
FALL "WEBWCRM (Hyphantria cunea Brury)
Georgia 0* 1% Snapp (August 18): The fall webworm is unusually
abundant in middle Georgia this year, near Hawkinsville, and
is doing considerable damage to pecan trees,
John B* Gill (August 2): The fall webworm is very prevalent
in pecan orchards in many sections*
PECAN-NUT CaSE-BEARER (Acrobasis hebescella Hulst) .-
Georgia John B. Gill (August 2): We find that the second brood of
the pecan -nut case-hearer has not been so destructive. The
first-brood larvae, appearing during the latter part of May
and the first week of June, caused very serious damage to
the crops in various pecan orchards in southern Georgia and
northern Florida, According to our observations the worst
infestations occurred around Bacanton, Ga.
#EC AIT-LEAF CASE-BEARER (Acrohasis nebulella Riley)
Georgia John B. Gill (August 2): Practically all adults of the
pecan-leaf case-hearer have emerged and oviposition has "been
taking place in peach orchards for some time. The very small
larvae are now feeding on the under surface of the leaves,
and, judging from the ahundance of larvae at this date, the
insect will go into hibernation in great numbers* On account
of the restricted fieeding "by the larvae during the late
summer, no serious damage is done at this season of the year,
"but when abundant, the larvae are very destructive to the
unfolding buds in the spring. We have succeeded in perfecting
a very good control of this pest, and during the next month
and early in September many pecan growers in this immediate
section will he spraying their orchards for the protection
of next year ' s crop,
HICKORY NUT WEEVIL (Belaninus caryae Horn)
Georgia John B* Gill (August 2): Peean growers in Lamar County have
reported serious losses to pecan crops through the attacks
of the pecan ■weevil. During the early part of July the
writer made a trip through thas territory in order to look
-2U0-
Georgia
into the pecan weevil situation. Larvae were found at
varying depths in the soil in pecan orchards5 but from
observations made it was impossible to predict or determine
the infestation of the nut crop for this year* The adults
will likely be occurring on pecan trees during the early
part of September ard will continue their attacks until the
advent of cold weather,
LITTLE HICKORY APHID (Monellia car y el la Fitch)
John B. Gill (August 2) : The Little hickory aphid has been
occurring abundantly on pecan trees during this season. This
species appears to confine its attacks to the underside of
the leaves, and so far it has no't been observed feeding
on the young nuts. The foliage of heavily infested pecan
trees often becomes drenched with the honeydew exudations.
At present this insect is not considered as a serious pest
to pecans.

and cauliflower. It is also found in late potatoes and
various other crops and weeds. Trenches had to be dug
around some fields, I have counted 25 under the small
lumps of dirt at the base of a small plant k inches high.
A, M* Hollister (July); Cutworms have done about the most
damage of any pest in Saratoga County, In the southern part
of the county, where considerable truck gardening is
carried on, they have been very troublesome. Many farmers
have used the bran, Paris green and molasses poison and in
this way have done good control work. It is difficult to
make an estimate of the damage done by these pests.
H. A, Gossard (July 25): One of the glassy cutworms was
received from Conway June 25, where it was said to be
attacking beets.
GREEN SOLDIER-BUG (llezara hilaris Fitch)
J, J. Davis (August 22): The green soldier -bug has been
reported from sections of the State from the extreme south
end to the northeast corner of the State. In most cases it
was simply reported as abundant and no apparent injury
noted. The first record was from Delphi on July 25. In
several localities it was reported on corn, and one
correspondent blames these insects for the unthriftiness of
one section of this corn field. It was also reported as
occurring on peach, but the correspondent has not advised
us that injury ©ccurred. At Corydon and south to the Ohio
liver we found this insect abundant on Lima beans August
20. Young and adults were observed with their beaks inserted
in the green pods and in the stem at the base of the pod.
The beans have not developed or are deformed in the pods,
and as there is no disease present, and since the injury is
what we might expect, it seems very likely that the soldier-
bug is responsible.

Michigan Eugenia McDaniel (August 18): The green soldier -"bug has
bEen .received this morning from Cass County, Mich, .where
it is said to "be attacking "beans in the field. The insects

POTATO
COLORADO POTATO BEETLE (Leptinotarsa decemlineata Say)
Massachusetts A. I. Bonfne (July 25): Infestation has been rather uneven
throughout the State, In this particular region, Amherst,
the pest has "been somewhat more abundant than for several
years, whereas from other sections of the State, notably in
Barnstable County, there have been so few beetles that up
to the first or middle of July it had not been necessary to
apply any arsenate of lead for their control. The pest is
apparently not more than normally abundant except in isolated
areas.

Roy Latham (July 15): Slugs have not been known to be so
abundant in years in Suffolk County. Arsenate failed to
kill them although more than usual was used. Many had entered
the ground and were out in hard-shelled beetles by July 10,
Not in 20 years have so many gone into the ground as a! the
present time. In fields that were red with them they habe
gone into the ground after being sprayed three times. This
looks bad for next season's early crop.
H, A, C-ossard (August 20) : Perillus bioculatus Fab, was
received from Shelby August 1, where it was reported to be
doing very effective work in destroying the Colorado potato
beetle,
R, L, Webster (August 3)* Reports from county agents in
northwestern counties indicate that many fields have been
severely injured this year,

W„ D. Mills (August H): Infestation has been severe, but
showers have reduced the numbers of lice in Nassau County.
Indiana H. F, Dietz (July IS): Earlier in the season tomatoes were
attacked by the potato aphid. These infestations were pretty
well cleaned up by the ladybird beetles, especially the
convergent ladybird, the nine-spotted ladybird, and the maculate
ladybird. As a result of this infestation, however, many
tomatoes are showing infection with mosaic and spindling
sprout disease at this time,
Wisconsin A, A. Granovsky (August IS): Potato dF$el<ais of Door County
are infested with two principal aphids, Macro siphum solanifolii
Ashm. and Myzus persicae Sulz. The first, however, occupies
a secondary place in number, Myzus being more common. Injury
is not considered serious.

T« H. Parks (August 21): This insect is now present in its
usual injurious numbers in most fields of potatoes. Hopperburn
is killing the tops of unsprayed plants in central and
southern counties v/here the crop was planted in May, This
is the sixth successive year for such damage.
J» J„ Davis (August 22): The potato leafhopper is gradually
increasing its area of destruction each year.
W. P. Flint (July 26): The potato leafhopper has been very
abundant this season on potatoes, beans, and alfalfa! .
A. A. Granovsky (August 19): Potato leafhopoers are very
common, injuring potato fields by causing hopperburn. The
disease appeared in the first part of August and on some
early varieties of potatoes symptoms were present in the
latter part of July,
P. A* Fenton (July 2S) : The potato leafhopper is not as
serious as it has been for several years and will not
very seriously affect the potato crop in the State this
year, although in certain localities it has been
destructive to potatoes.

CABBAGE Mffl-GOT (Hvlemyia brassicae Bouche)
Massachusetts A. I. Bourne (July 25): The cabbage maggot in some
sections of the Stare has apparently attained numbers
considerably greater than last year. In Bristol County
cabbage and cauliflower are reported as being seriously
attacked. Damage already caused is estimated at about
20 to 25 per cent. Where QO'rrosive sublimate treatment
has been carried cut. the damage has been cut down to a
comparatively insignificant figure. Injury to radishes from
this ir.sect throughout the market garden section of the
western part of the State has apparently been very serious.
At least one plat was entirely spoiled by the maggot. This
particular crop, not lending itself to the corrosive sublimate
treatment, suffered considerable damage.
Ohio H. A. Gcssard (July 25): The cabbage maggot was received from
Beaver dam 'June 6 and from Medina June 15, on cabbage plants.

Buncombe and Madison Counties.
Georgia J, 3, Gill (August 1): The Mexican bean beetle has been
observed in gardens around Thomasville, throughout the season. The
adults and larvae have been very abundant on snap beans and
Lima beans, upon which they caused very serious damage. Within

the past two weeks they have been observed on cowpeas
growing in gardens around town. This species does not seem
to attack the cowpeas when there are beans for it to feed
upon.
^io Neale F. Howard (august lU): The Mexican bean, beetle larvae
have been found at Waver ly. This is in north-central Bike

STRIPED CUCUMBER-BEETLE (Diabrotica vittata Fab.)
Massachusetts A. I. Bourne (July 25): The striped cucumber -beetle seems
to be somewhat more prevalent than it normally is throughout
the State, all our records on these beetles bearing out this
statement, with the exception of Bristol County, where the
County Agent reports that while normally abundant they do not
seem to be in any greater numbers than last year. Lusting
-2^2-
and spraying are very generally employed in their control,
particularly in the marltet garden section in the eastern
part of the State, and seen to be giving more or less
satisfactory results. One factor which has been noted
regarding then, particularly in Middlesex County, is that
they apparently started later in the season than normally,
and this will account for the fact that they are at
present abundant in the stems and blossoms, when under usual
circumstances their injury would be practically over at
this period..
New York Henry Dietrich (July): The striped cucumber-beetle has
been readily controlled with nicotine dust.
West lirginia W» E. Rumsey (August 15): Leaf injury occurs as usual,
but the most serious loss is from larvae in roots. June

judge that the brood was more numerous than in 1P06 and that con-
siderably more damage was dene to young orchards and to forest

Middlesex County, has found but one gipsy moth caterpillar in his
orchard this season. It is very evident therefore that both the
gipsy moth and the brown-tail moth are proving considerably less
abundant than is normally the case.
BROW-TAIL MOTH (Euproctis chrysorrhoea L.)
Massachusetts A. I. Bourne (July 25): Mr. Fiske of Lunenburg states that in
hiar orchard the damage was practically nil and the brown-tails
were virtually extinct. The same condition prevails in northern
Worcester County, where this season Mr. Calkins , reports prac-
tically no brown-tails seen this year. Mr. Farrar, of Middlesex
County, reports seeing no brown-tail caterpillars or moths this
year. They were noted, however, in considerable abundance in
the region of Woods Hole, down at the heel of the Cape.
ELM SPANWORM (EnnomQs subsignarius Huebn.)
New York R. E. Horsey; The snow-white linden moth is very common near
lights July" 9, a few still to be found July 13, none last year
but a swarm on June 27, 1921. at Rochester.
WHITE-MARKET) TUSSOCK MOTH (Kenerocampa leucostigroa S. & A.)
New York V. E. Peterson (July): Spraying for the caterpillar of the tussock
moth, which has infested the trees of Buffalo in great numbers, has
just been finished. Conditions have been worse this year than for
some years previous.
R. E. Horsey (July 17): The' white-marked tussock moth was reported
very scarce at Rochester, but two horse chestnut trees were found
stripped of foliage, perhaps more this year than in 1922, as none
were reported last year.
Ohio H. A. Gossard (August 20): The white-marked tussock caterpillar
was received August 8, from Geneva on grape and on August 17 from
Columbus on plum and elm. This insect has been observed to be
numerous in several Ohio localities. It is more plentiful than
it has been for some years.

B/GY70RM (Thyridopteryx pphemeraef ormis Haw.)
New York Henry Bird (August): The serious drought which has prevailed
for months has apparently caused insect life to be less abundant
than is usual at this time of year* The bagworm, although it
occurs scatteringly in somewhat greater numbers than usual at
Rye, has not oeen really abundant. Parasites seem to have held
it in check.
C. R. Crosby (.August 6): Trees are badly infested at Oyster Bay.
M. D. Leonard (August 8): It is reported that the whole hilltop
around the Richmond Country Club grounds is infested. Just what
trees are infested was not learned. The Dougan Hills Improvement

Haute south to the Ohio River, i.e., a little more than the southern
third of Indiana. The species occurs principally on arborvitae
and other conifers, but some injury is done to deciduous shade
trees .
L. Haseman: Numerous complaints continue to come in about the
bagworms, especially on evergreens,
F. C. Bishopp (August 25): Bagworms have been very abundant on

red birch and I suppose elsewhere.
CAT ALP A
CATALPA SPHINX (Ceratomia cat alp ae Boisd.)
Ohio E. W. Ker.denhall (August 17): The catalpa sphinx is doing great
damage in southwestern Ohio in nurseries and forests. Some spray-
ing and dusting is oeing done.
ELM
ELM LEAF-IflNER (Kaliofenusa ulmi Sund.)
New York R. E.' Horsey (July 17): The elm leaf-miner is rather more common
than usual. Some small trees with their leaves badly disfigured
are to be found in Highland Park.
EUROPEAN EL!! SCALE (Gossyparia spuria Modeer)
New York R. E. Horsey (July 17): The elm bark-]ouse was sprayed on July 6
and 12 while moving. Very little occurs in Highland Park and on
streets, but a new infestation has been found in street trees in
a nearby section of the city.
New Jersey R. 3. Lott (August 21): This scale has been noted as very plenti-
ful on a row of elms at Eound Brock.
Ohio H. A. Gossard (July 25): This insect was received from Covington,
Columbus, Dayton, Akron, Salem, and Tiffin,
FLATHEADED BORERS •'
Texas F. C. Bishopp (August 25): Borers which have been determined by
R. A. St. George as Chrysobothris so. have been unusually abundant
under the bark of this year's planting of sycamore and elm trees
on the streets of Dallas. Practically 100 per cent of the trees
are infested. Often the number of borers in one of these small
trees may run as high as 15. Tne oriental sycamores which are
now being tried as shade trees in this section are infested equally
as badly as the native. If it were not for the continual worming
of the trees by the city forestry department these borers would
bring about the destruction of practically all trees set last spring
A goodly number of borers were also present in two and three-year-
old trees, but they seem better able to withstand the attack.
ELM LEAF-BEETLE" (Galerucella luteola Huell.)
Massachusetts A. I. Bourne (July 25): One or two cases cf infestation of the
elm leaf-beetle on elms immediately around Amherst have been ob-
served within the last week. The larvae are practically mature
at this time. This is about the first instance of the presence
of the beetle in Amherst for a period of about eight or nine years.
No reports of serious infestation throughout the State have been
brought to our attention, however. The pest is apparently begin-
ning gradually to "come back" after a lapse of several years.
Connecticut Philip Garr.an (August 23): These beetles are severely damaging
trees in Fairfield County, being more abundant than last year.
New York R. E. Horsey (August): A very bad infestation was found in
Rochester. The leaves were badly skeletonized and a large number
of grubs were at the base cf the trees, while a number were still
feeding. The first of the month we sprayed about 30 trees here.
This insect is slowly spreading but where spraying is thoroughly
done can be kept under control. The greatest proolem is traffic
and the objection of people to having their houses spotted by the
spray material.
ELM BORER 'Saperda trident at a Oliv.)
Nebraska M. H. Swenk (August l) : Elm trees were reported injured by the
elm borer.
ELM APHID fMyzocaiiis .ulmif olii Monell )

and spraying with he ivy oil emulsions was carried out.
HICKORY
HICKORY BARK-BEETLE (Scolvtus quadrispinosus Say)
New York Henry Bird (August): This insect, which in former years badly
infested more than 75 per cent of all hickory trees in this section
and more than 95 per cent of all of the old trees, is apparently
at a very low ebb this season.

gall-louse on the cottonwood continued to be received during early
August. (August l) : In western Nebraska reports of injury to
cottonwood trees by the vagabond gall-louse were received.
OYSTER-SHELL SCALE (Lepidosaphes ulmi L.)
Indiana H. F. Dietz (July 18): The light-brown form of oyster-shell scale
began laying eggs on July 6. "The second brood should appear within
the next two weeks* The gray-brown form is in the early third
instar at the present time. We have no data on the apple form,
which is not serious in this State. In this connection it should
be pointed out that the nomenclature for the three different forms
of oyster-shell scale, published by Glenn in the Journal of Economic
Entomology for April, 1921, should be followed, i. e., the JLi£ht-
brown f orm ,v/hich is two-brooded and which lives on Carolina poplar
birt cannot maintain itself on apple; the apple form, which is like-
wise two-brooded and lives on apple but cannot live on Carolina
poplar; and the jgrajr-brown form, which is single-brooded but cannot
maintain itself on apple, at least in this State.
PALE TUSSOCK MOTH (Kalis idota tessellaris S . & A. )
New York R. E. Horsey (August): This insect has given us more trouble than
any other pest this month. It is found in all parts of the city
wherever the plane tree is planted, as well as in Highland Park.
On several streets planted to plane trees the trees were sprayed
and we are still at it. In fact, this insect has done fully as
much damage to plane trees as the elm leaf-beetle did to elms.
COTTONWOOD LEAF-BEETLE (Lina script a Fab, )
New Jersey R. B. Lott (August 19): Near New Brunswick this insect is very
plentiful on willow and poplar, especially the latter.
Nebraska M. H. Swenk (August l) : In western Nebraska reports of injury to
cottonwood trees by the cottonwood leaf-beetle were received.
^August l) : Injury to the cottonwood trees in the City Park at
Callaway, Custer County, by the cottonwood leaf-beetle was com-
plained of during early August.

over the State wherever iris is grown in ornamental plantings.
It is invariably associated with the iris roct rot caused by
Bacillus carotoyorus . which completes the destruction begun by
the boner. Neither the insect nor the disease has been found

there has "been an almost unprecedented abundance of the stable
fly. The trouble is State-wide, reports of great annoyance
to live stock by these flies having been received from 31
different counties, representing all parts of the State. Serious
losses from a shortened milk supply among dairy cattle, lack
of gain among cattle on feed and range cattle, and much difficulty
of working horses in the field hav© been reported as a consequence.
