INSECT PEST SURVEY BULLETIN

Vol. 3 September 1,1923 No. 6


OUTSTANDING ENTOMOLOGICAL FEATURES IN THE TrITITED STATES FOR AUGUST.1923.

In this number af the Insect Pest Survey Bulletin statistics on the
summer Hessian fly surveys of New York State and Chio are reviewed. The
situation is reported as generally favorable in the Ohio River Vealley, while th.e infestation in New York State is ove- 7 er cent hi-hcr than lost year. In North Dakota very heavy infestations were observed th-roughout Golden Valley County, while in Nebraska this insect is present in the stubble in below normal numbers.

"he 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 southeastern South Dakota, vhile
both southeastern and northeastern portions of' Nebrasia are experiencing rather heavy cinch bug damage.

The corn earworm, 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 mort 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 damae by this pest.

The cotton leafwmorm 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 "d southward to 1Tew York and New Jersey. In 1ew England it is reported as having skeletonlzed 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.

The European red spider is now seriously abundant throughout New England, southward to M.aryland, pest Virginia ,and westward to Ohio.

The .exican bean beetle is reported from Adams, Highland, Pike and Scioto Counties in Ohio and is substantially spreading in the previously infested States.

The oagworm is generally serious throughout the IMiddle Atlantic, coutheastern and Ohio River States, damage extending westward to :Flissouri.


OUTSTANDING ENTOMOLOGICAL FEATURES IN CANADA FOR AUGUST, 19023.

Aphids generally are unusually numerous this year on all kinds of vegetation in hora Scotia, and much apprehension is being shown' on th;e part of orchardists and growers with regard to the numbers of several species of econcmic importance. The green apple aphid is more numerous in the Annapolis Valley than it has oeen since 1913. The rosy aphid is likewise very nurerous. 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 srall fruits than it has been this year in the Niagara district of Ontario. Black currants and raspberries are suffering particularly, the foliage turning brown, beccuing scorched, and the fruit crop in many instances being almost a complete failure.

The rose leafhopper, which occurred in outbreak form in apple orchards
in eastern Ontario early this season, has been reduced to insignificant proportions through natural agencies. Parasitism has been very heavy.

The lesser migratory grasshopper continues in the ascendancy at many
points in Canada. The outoreak in the southern Okanagan Valley of Eritish 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 some 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 least?10 per cent of the pods contain larvae.

The fall webwvorm appears to be numerous everrvhere in southern Jianitoba this year and also in the eastern townships of Quebec.

The spruce budworm is occurring abundantly in the neighborhood of Victoria, 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 Eumtrus strigatus 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.












CEREAL AND FORAGE-CROP INSECTS
I TS,' LLANFOU3 FEFDWRS

GRASSHOPPERS (Acridiidae)

North Dakota R. L. 17ebster (August 3): County agents report damage in Pierce,
Fiercer, and VcHenry Counties.

Nebraska 1. H. Swenk (August 1-15): Grasshoppers, mostly Yelanoplus
bivittatus, began to be complained of in Furnas and surrounding counties early in August. There have been complaints of grasshopper injury in other parts of western and central Nebraska, but
on the whole these insects are less injurious than usual this year.

Texas C. Tanquary (July 23): Reports of grasshopper injury continue
to come in from several counties of western Texas.

1THITE GRUBS (Phyllohaqa spp.)

Massachusetts A. I. Bourne (August 23): Numerous complaints have come to this
office relative to unusual abundance of white grubs from gery many
points throughout the State. Franklin, from East 'areham, 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 7rass
so that the turf could be rolled back easily like a carpet, exposing the grubs in such numbers that they could have been gathered by
the bushel." Complaints of these insects practically killing
large areas in la:mns have been received from several of our correspondents. 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 oeen seen picking at the spots as if seeking Prubs
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 bet"-een two
sheets".

Iowa F. A. Fenton (July 28): The June beetle, as predicted, has appeared
in swarms in southeastern Iowa in the counties bordering the 'ississippi, where they have defoliated large tracts of woodlands.

VIR,70 M-S (Elateridae)

Massachusetts A. I. Bourne (July 25): 17ireworms are occasionally causing considerable injury, although there is no general or widespread outbreak. Douotless 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.

HE.T

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 infestation 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 follovs:

Genesee 5.33 7ayne 18.35
Wyoming 1.60 Ontario 21.89
Monroe 7.74 Chautauqua 0.fO
Livingston 2.40 Yates 10.67





Ohio 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 w'as 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 educational 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 stra: s
infested and most of then lodged. Fulton County had one field sowed Sentember 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.

North C. N. Ainslie (July 27): Every field in Golden Valley County exDakota 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.

Nebraska 11,. H. Swenk (August 1): 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 Dason Counties in greater
numbers, on the whole, than in the counties intervening between them and the principal area of heavy infestation, 7,hich includes
Cass, Otoe, Neaha, Richardson, Johnson, and Pawnee Counties.






-220


WHEAT-SHEATH GALL JOINTOW (Harmolita vaginicola Doane)

Ohio H. A. Gobsard (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.

VHEAT-HEAD ApOP"mP (Helioohila 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 EAT SA'7FLY (Cehus cinctus Nort.)

North R. L. Webster (August 3): The Burke County agent reports that inDakota festation running as high as 80 per cent has been found in this
county. (August 13): Severe damage was reported from Burke,
Ward, Bottineau, and Towner Counties.

GREAT PLAINS FALSE iPJR T0p (Eleodes opac Say)

Nebraska M. H. Swenk (August 1): 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 reduction 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 reported in early June that he had had 300 acres of wheat destroyed
by this insect.

ENGLISH GRAIN APHID (.Tacrosiphum granarium Kby.)

Nebraska l. H. Swenk (August 1): 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 sufficiently numerous to threaten corn anywhere.









-221

Ind-Lana J. J. Davis ( ugust 22): Eggs of the chinch bug were abundant at
Monticello 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 danrage w,.as 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 chnrch bugs in his oat f ield.

F. A. Fenton (July 28): The chinch bug is present in injurious
numbers in the southeastern part of the State. The present distribution of this pest is greater than that of last year, showing
that it is on the increase in this State.

MAissouri F. D. Butcher (July 24): The county agent at !Maryville reports
that chinch bugs are injuring corn about 7 miles south of the Irowa
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, Rails,
Bates, Boone, M1anes, M"iller, Morgan, and Lincoln.

South C. N. Ainslie (J44uly 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 1". E. Swenk (August 1): The c-hinch bug has been destructively abundant during July in three separated areas of the State. One of th1-ese
areas, in the southeastern part of the State, includes Richardson,
Pawnee,, Gage, and eastern Jefferson CouruIties, and extends northward into southern Nem=aha and southern Lancaster Counties The centers
of injury in this area are around Humboldt, Piuburn, Table Rock,
Pawnee City, Wymore, Adams, and Firth. There is also some local
injury in Saline County. A second area lies in south-central Nebraska and includes Franklin an', 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, but was still in progress in the third
area at the end of the month. Ch the whole, the chi-nch bug, has done more injury to corn in Nebraska this month than at any time
since the summer of 1910. Weather conditions con-tinue favorable









-222

for these pests, and if their present numoers ar: augurented normally oy the second generation during August, very -enacing number
of chinch bugs will go into hibernation in these infested areas this
fall. (August 1-15): The chinch bug continued to do injury me
corn in the second area of infestation during the first eek in
August in diminished intensity, extending est into Furnac and
north into Dawson Counties. By August 10 the second brood develoning in the corn was under way.

CORN EARrTOr (Heliothis obsoleta Fao.)

IHaine E. 1. Patch (August 1): The county agent from Freedom writes:
"This pest has quite a foothold in this town."

New York C. R. Crosoy (July 18): A correspondent from Middletown says:
"This grub is raising h__ with my corn."

1Test W. E. Rumsey (August 15): Early s'ce corn at Yorgan own s'o os at
Virginia least 10 per cent of the ears attacked.

Ohio H. A. Gossard (August 20): '7e had an inquiry from Cleveland Ju
26 for control measures for this pest, also from Bruns'iok August 1, and from Lakewood August 15. This insect is injurious this E -son
over southern Ohio, though not so damaging as it was in the o rer
of 1921.

New Iexico V. E. Emery (August 1): This insect in Dona I.na County is very
abundant and is doing considerable derage to the ear torn. In the northern part of the county where corn is tasseling abo ut 20
per cent of the tassels have been destroyed.

STALK BORER (Panaioema ritela Guen.)

Maine E. Y. Patch (July 21): A report from South Portland says: "Ten
per cent or more of my tomato plants are riddled by th. Lately
I found them working in the potato tops." (July 30): I found
acout 50 in potatoes and some in sweet corn. (July 31): A rerccrt
has oeen received froL North Haven. (August 2): A report has
been received from Richmond.

Massachusetts A. I. Bourne (4ugust 23): The potato or scrn stalk borer is practically through its work for the present season. The larvae are nearly mature and beginning to leave the nlant. Thi s insect has
apparently been unusually abundant this year. -any 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 reasure
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 normally.









-223

Rhode Island A. E. Stene (August 18): Ancther 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.

Connecticut 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, Hamden, anc Stratford as attacking corn, tomato,
and pepper. It is rather more abundant than in an average year.

Ohio H. 'A. Gossard (July 25): The common stalk borer was received from
all over the State.

Indiana J. J. Davis (August 22): M:ost of the repoorts received the last
month are of nearly mature larvae in large corn stalks, where they
are doing little damage.

Illinois W. P. Flint (July 26): The common corn stalk borer has been sent
in from many localities from small grain, corn, and ornamental
plants.

Iowa 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 and dahlia, and also has done
some injury to tomatoes.

Missouri L. Haseman (July): This pest was very abundant and destructive a
little earlier, and many complaints about it were answered.

Nebraska H. Swenk (August 1): 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, ho,-ever.

ATM70T (Cirphis unipuncta Haw.)

Nebraska M. H. Swenk (August 1-15): During the first week in August the
true arnywvorm appeared in Holt and Scottsbluff Counties, doing
considerable local damage in late oat fields. The ar.yworm outbreak, however, was not at all general.

ALFALFA AND CLOVER

ALFALFA 7EEVIL (Phytonomus posticus Gyll.)

California 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









-224


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.

California Weekly News Letter, Vol. 5, No. 16 (August Ii): In 10
days at inspection stations on the California-Nevada line, maihtained by the California Departrent of Agriculture, there were
taken from 12 automobiles 126 live alfalfa weevils.

FALL AMR 0 MYWOR (LaohygMa fruginerda S. & A.)
Florida F. S. Chamberlin (August 10): Report of injury to young corn has
been received from Qtuincy. The crop was badly damaged.

GARDEN W7EBJ0P, (Loxostege similalis Guen.)

Iowa C. J. Drake (July 27): The garden webworm has appeared in considerable numbers during the past week. At 1relbourne and Woodbine it has been reported as destroying fields of alfalfa. At Knoxville
and 17oodbine 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 destroyed.

Nebraska M. H. Swenk (August 1): During the two weeks from July 13 to July
26 many fields of alfalfa in eastern Nebraska were badly dar? ed by
this pest. The worms, as usual, spun the tops of the plants writh
webbing and ate the leaves. The injury was confined to the part
of the State lying east of the 99th meridian, and see~red to be quite
general over this area. Reports of injury were especially corron from Richardson, Pawnee, Gage, Jefferson, Thayer, Buffalo, [errick,
Platte, Sarpy, Douglas, W7ashington, 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 webworn continued 'rith reduced intensity during the first I0 days of August. Before the
last of the reports of injury of the second brood. were received from
northern Nebraska, great swarms of moths hd appeared in southern Nebraska, and are still flying at the present writing, indicating
the probability of continued injury by the third brood of the webworm late in August and early in September.









-2 25Keaaas, 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 arid Sedgwick Counties, Kans. to and including northeastern Few 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 V1. C. Tanquary (July): During 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 COR~N BORER (Pras nubilalis hulpbr.)

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 k'rood.

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 tire. (August
20): 'Most of the moths of the European corn borer brood have
emerged in most of northern Ohio and at the present tire egas
are found upon the corn blades and the larvae are found in the corn stalks and, under some circumstances, in weefts where corn is not available. Notwithstanding a thorough burning campaign
and clean-up in Ashtabula County last spring, there is an increased number of borers this season, clearly indicating that
there were more 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 BOR~ER (Diatraea saccharalis Fab.)

New Mexico R. Middlebrook (July 20): The species Ditaasacaai and
D. zeacolella. have been reported from the eastern counties of
The State. They are getting worse each year. The crop is
ddmaged 30 per cent.

A STALK BORER (fliatraea lineolata W7alk.)

New Mexico J. R. Horton (August 1): Corn damage, estimated by counting 100
stalks in each field, covering most of quay County, varies frcm
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.









About 1 to 2 per cent of stalks of milo is damaged in some fields
as hightas 10 per cent in first tw,7o or tre-- ordering infested
corn, in one field.

CLOVER ROOT-B0OER (Hylastinus obscurus Marsh.) Ohio H. A. Gossar6 (August 20): The clover root-borer was received from
Strongsvila A, le t 6, where it had destroyed a field of clever.
I also received the sae insect two or three days ago from a "ayne 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.

CLOVERLEAF TFEVIL (Hypera ounctata Fab.) Ohio T. H. Parks (August 21): This beetle was sent by the Erie County
agent August 14, with the statement that the insect is working g 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 (Sitona hisnidulus Fab.) Indiana J. J. Davis (August 22): Injury to roots of alfalfa reported from
Hartford City, in Blackford County.

Illinois W. P. Flint (July 26): Sitones (sp?) has caused serious damage to
the roots of old stands of alfalfa in central Illinois.

CLOVER-SEED CATERPILLAR (Lasoevresia interstinctana Cler.) Iowa C. J. Drake (July 27): The clover-seed caterpillar has been reported in Washington County. It seems to be numerous in several
fields.

-MPRKED CUT0P, (Noctua clandestina Harris) Illinois W. P, Flint (July 26): This insect has been reported from several
sections in northern Illinois as destructive to sw:eet clover where this plant is grown for seed crop. Parasites are fairly abundant.

MISCELLAYEOUS

COTTONY GRASS SCALE (trio eltis festucae Fonsc.)

New York C. R. Crosby (July 16): Grass infested with this pest was received
from Gravesville.
A SEAT-BEE (Halictus virescens 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-BFFTLF (Chelvmorrha. 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 pon DeG.)

Massachusetts A. I, Bourne (August 23): Green aphids have not been
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.

New York 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 infested with the young aphids.

F. H. Bond (August 4): The lice have appeared on apple
in serious numbers in some orchards at Osvego.

H. W* Fitch (August 4): They are very numerous at Sodus
on apple. (August 11): They are very abundant on McIntosh,
Greening, and Baldwin 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. ierstorff (August 11): The green aphid is reinfesting
the apple seedlings and they are still abundant on Spiraea
vanhoutti, at Honegye Falls.

ROSY APPLE APHID (Anuraphis roses Baker)

Ohio H. A. Gossard (July 25): Aphids of many species have been
active and conspicuous. The rosy apple aphid attracted
attention frcm many quarters of the State.

Indiana H. Fs Dietz (July l): The rosy apple aphid was unusually
bad this year and damaged between 15 and 25 per cent of the
crop in many localities before it migrated.

CODLING MOTH (Carpocapsa p omonella L.)

Massachusetts A. 1"6 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

irrcFlar, owin; probably to the continued cold weather prevailing durinz- 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.

New York G.E. Smith (A%,u{st 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): Cdling moths are causing severe
injury on apples in Mionroe 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 Osr'ego County.

H. W. Fitch (August 11): First-brood larvae continue to
enter the fruit on the shore of Lake Ontario. No secondbrood larvae that could be identified as such have been
found at Sodus.

Indiana B, A. Porter (August 6): Second brood larvae began leaving
the fruit between August 3 and 6 at Vincennes.

APPLE A1 THORN SXEETONIZER (aemtrorhil ]rfia Cl-c))

Massachusetts A, 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.

Connecticut E. H, 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. D. Clark (July 24): This is the second brood of this pest and it is found generally throughout Fairfield County.
Many leaves contain from 3 to 6 latvae. It is more abundant
than last year.

W. E, Britton (Atlgust 21): This pest is less abundant in the southwestern portion of the State but is 'nore abundant
in the eastern part.

Rhode Island A. E. Stene (August l): 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. P. 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, L I., \'ho states that
this pest is unusually bad this season. (Au ust 13): P..
Eastman of the New York Department of 7arrs and Mrkets
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 an le and thorn
skeletonizer in a small appl e orchard of about 50 trees at
Fompton. This is about S miles northwest of Paterson. Last year these trees were under my close observation during the entire groTin, season and there -as no evidence of the pest
at that time. i s far as I kno? this is the first record for
this State.

T~T CATEPILLn (:Talacosoma mericana Fab.)

Massachusetts A. I. Bourne (J-oly 5): C t e of the apple tent
caterpillar were seen in A vet on July 3. Since that
time they have been found in considerable abundance.

New York Clark Hutchin-on (Jy 21): t ; urg, in St. Lawrence
County, mos o' the cater-illars -e:d 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 7reat amount of damage. I have noticed some farmers
spraying their orchards.

New Jersey R. B. Lott (August 5): Erg masses of apple-tree tent caterpillar have been noticed throughout State. They are quite
plen t i ful.

FALL 'T3:ORI: (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. Foerrar reports that
in his estimation the pest is approximately ;0 per cent
as abundant as latt year.

Connecticut H. P. Zappe (August 22): Infestationsooccur on ash, cherry,
apple, etc., in Hartford, 7indham, and Jew London Counties.
The webworms are more plentiful than they iere 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.







-230



H. L, McIntyre (August 8): A bad infestation has been
reported on a number o-willows at Baker's Mills, In Warren
County.

F. Illig (August 11): The fall webworm is abundant in
several localities in Wayne County.

Ohio E. 7. Mendenhall (August 22): We find them bad in old neglected
orchards and in a variety of nut and shade trees in southwestern
Ohio. They are noticeable along roadsides.

Indiana H. F. Dietz (July 18): The fall webworm is unusually abundant
in cities and tons, 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 (Augist 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 habe
not been properly sprayed.

Nebraska 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.

TRNTISHED PLaYT-BUG (Lyeus pratensis L.)

Connecticut M, P. Zappe (.August 1): This pest is causing serious injury
to apple and peach stock in nurseries, and is also working on the
tips of dahlias, at Durham, IVillimantic, and Hamden. It
seems to be doing more injury than in the average year.

New York A. L Pieretorff (Agust 11): At HoneQpe Falls this pest is
common on practically all young trees and shrubs in a nursery.

LE-FHO0PPERS (Jassidae)

New York M. 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 appreciably 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 Honeoye Falls. Instead of making
the characteristic mottled injury, they seem to curl the apple
leaves much the same as aphids, but not qite so severely.







-231

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

Massachusetts A. I. Bourne (July 25): In #orthern 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.

Ohio H. A. Gossard (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 be
found in the various treatments. Of course, there may be
later developments which will have some significance.
Some unsprayed trees in northern Ohio have an abundance
of San Jose. (August 20): San Jose scale was received from
Shiloh August 2. Specimens of apple were quite spotted over
by it.

Indiana 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 proClaced 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): *7ith 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 ara will stress dormant oil spraying
the coming season. Until las year the scale was not
recognized as a serious pest on peach, but this year several
peach orchards have become alarmingly infested.

Illinois W. P. Flint (July 26): The 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. & F,)

Massachusetts A, I. Bourne (August 23): The European red mite is apparently normally abundant generally, with occasional
regions of sl ightly greater abundance. The protracted dry
spell which persisted up to the early and middle part of the
motth was very favorable 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





-232

a dust treatment, the mites were apparently much more
abundant than on adjoining blocks which had been sprayed.

Connecticut Philip Garman (August 1-23): Baldwins show considerable burning at Branford and 'allingford. 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 ->l 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 tom-rfruit 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 (AguLat i5): 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 =ite has .
appeared very nurerously in northern Ohio and is known to
be present in Treat numbers in orchards as far east as
Youngstown and as far west as Toleo. It is causing severe
btowning of the leavAs of aple, pln and peach, Hembers
of our staff have given it J es~o ~ilention at Youngstown,
in the peach orchards abouL D2bLy, and in plum and apple orchards at 7aterville. I; was reported very numerous on
spedimens of apple leaves sent in from Toledo July 12.

G. A. Runner (August 11): This insect is abundant on many
fruit trees and ornamentals in the vicinity of Sandusky.
Wnsprayed grapevines have been observed which were heavily
infested, but injury to foliage seemed slight compared to injury to foliage of peach and apple. It is also abundant in many apple orchards in counties bordering on Lake Erie.
Foliage injury is severe in orchards in which lime-sulphur
has not been used in su-mmer 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 11 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.









AILLOU CURCULIO (Cryptorhynchus lapathi L.)

Michigan R. H. Pettit (August 9): Yesterday we discovered some apple-s
that had holes eaten in them and in the course of an hoaui'
or two we found that Cryptorhvnchus 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 Cry-ptorhynchus
that he had actually caught in the act. He said a large proportion of his ripening plus 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 (Yetachroma interruptum Say)

Indiana J. J. Davis (August 22): Injury to apples by an unirnown
insect was first reported by Dr, B. A. Porter, who found,
on July 13, considerable injury to the fruit of Grimes
trees. The surface is more or less covered with gougedout 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. 77hen 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 interrupt-m 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 16. 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.

PF AR

PEAR PSYLLA (Psylla nrriceal Foerst.)

Connecticut Philip Garman (August 20): This pest is severely injuring
a large pear orchard at Southington.

New York 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 4): The weather has been very favorable for pear psylla development, and considerable honeydew covers
fruit and foliage in some orchards in Orleans County.








-34


H. W, Fitch (August j): This pest ia abundant enough to
cause many growers at Sodus to spray.

F. H. Bond (August 4): At Oswego the psylla has become had
in some orchards. (August 11): The psylla outbreak seems to
have subsided.

R. J. Palmer (August 11): The p7syll 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.

PE.AR SLUG (Cliroa cerasi L.)

Ohio Ho A* Gossard (July 25): The pear slug was received from Apple
Creek July 14 on p(ar (August 20): This pest was received
from Columbus Atiugust 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 bykthe pear slug have been received during the month.

PEACH

PEACH-TWIG MOTH (Anarsia lineatella Zell.)

Indiana H. F. Dietz (July l): 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, Ko. 15 (July 28): The
season of 1923 has not been marked by serious darage from the
peach-twig borer and there has not bec Ls ri h Cue to
unsprayed orchards as to some spra-ea orc arrs las year. 7e have no difficulty in controlling t'-e -es' t 2th lIme-sulphur
spray and expert to continue sJ.y-g V, iUh iir -suiphur in
the spring, as in the past, since urider conditions at Gntario
such treatment insures against severe damage from either
"curl leaf" or twig-borer.










-235

SHOT-HOLE BORER (colytus ru-ulosus Ratz.)
New York Henry Dietrich (July): The shot-hole borer is fairly injurious
in peach orchards at Appleton.

Ohio 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 24 regarding control measures for
this species.

PLUM CURCULIO (Conotrachelus nenuphar Hbst.) Georgia 0. I. Snapp (August 20): The second generation will be 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 9,600 cars of peaches were shipped from Georgia this
season, and the general quality of the fruit was the best since
1919. The curculio has been remarkably well controlled.

A"I'12BLE BUG"(Phanaeus tarnifex L-.) New Mexico W. E,. Tmery (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) Maryland C. C. Hamilton (August 22): Determination was made by comparing
injury with that reported in Ohio (Bul. 310 on the green soldierbug). 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 accur at
Belair and Havre de Grace,
Ohio H. A. Gessard (August 20): The green soldier-bug 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 Comst.)

Georgia 0. I. Snapp (August 20): At Fort Valley the San Jose scale
has increased rapidly during the surrn.er months. Some growers,
dissatisfied with the results from liquid lime-sulphur or
its substitutes, will use lubricating-oil emulsion this
winter.

ORIEiTAL PEACH MOTH (Laspeyresia molesta Busck)

Connecticut W. E. Britton (August 24): Many terminal shoot have been
tunneled by larvae at Greenwich. A few were noticed last
year in the same section. They are more abundant than in an
average year.

CHERRY

BACK CHERRY APHID (Myzus cerasi Fab.)

Wisconsin A. A* Granovsky (August 1S): Cherry qphid attacks cherry
orchards year after year in the locality of Sturgeon Bay, Injury
is largely done in a localized spot. Injury may be considered
as severe, producing yellowing and defoliation of trees, as
well as reducing the growth of terminal shoots an&, consequently,
the yield of cherries. Early cherries were more infested
than late varieties.

PEAR AND CHERRY SA7iFLY (Caliroa cerasi L.)
Indiana 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 cinpalata Lnew)

New York Henry Dietrich (July): There is a considerable amount of
infestation this season at Appleton.

H, W. Fitch (August 4): One tree examined at Sodus showed
32 per cent of the fruit infested.

PL M

PLUM CURCULIO (Conotrachelus nenuphar RTbst.)
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.








-237


Louisiana T, H. Jones (July 24): Infested peach fruit was sent in by"
Mr. M, J. Voorhies, County Agent of St. Martin Parish, with
the report that "we seem to have the same trouble all over
the parish."

RASPBERRY

TWO-SPOTTED OBEREA (Oberea bimaculata Oliv.)

New York C, R, Crosby (August 1): A patch of raspberries was badly
infested at Skanbatelez. (July 12): A small plot was badly
infested at Binghamton.

RED SPIDE (Tetranychus tpp.)

Ohio E. W, endenhall (July 26): Red spider mites are found general
in the State, infesting raspberry plants and doing some damage.

EUROPET FRUIT LECANIJM (Lecanium corni Bouche)

Iowa F. A. Fenton (July 29): A simple of several raspberry canes
was received literally plastered with adult scales of this insect. This scale insect had been a very serious pest on
these raspberries.

CRanTBERRY

SPOTTED CT7 0MI (Agrotis c-nirum L.)

Massachusetts 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 flovage 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

ROSE CHAFER (Macrodactylus subspinosus Fab.)

Massachusetts A. I, Bourne (July 25): The rose chafer has been unusually
abundant the present season, practically throughout the
State, and lrs not only caused coniderable 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.








-238

New York Ms D. Leonard (July 27): This pest is abundant on bayberry
and several other plants outside of Jarnica, L.I., near a
pond.

F. J. Whaley (August 4): There were several bad 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-SPCTTED FORESTER (Alypia octomaculata Fab.)

Ohio H, A. Gossard (July 25): The cight-spotted forester came from
Windham July 6, where it was attacking grape.

Indiana H. F, Dietz (July 1S): 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-BERY MOTH (Polychrosis viteana Clem.) Louisiana f, H# Jones (July 16): Larvae and injured fruit have been
sent in by Mr. M, J. Voorhies, County Agent of St. Martin
Parish, with the report that the larvae are "injuring grapes
in this section."

GRAPEVINE APHID (Macrosihum illinoisensis Shim.)

Massachusetts C, R. Crosby (August 15): Infested grape leaves have been
received from Harwich.

New Jersey M. Do Leonard (June 10): The grapevine aphid is abundant on
young leaves and tips of shoots in a small grape arbor at
Ridgewood.







-239

CURRANT

STALK BOR~a (Papaipema nitela Guen.)

New York M. D. Leonard (July 17): Mary K. Peters of the Farmingdale
School of Agriculture, L. I., reports that a patch of red currants are badly injured by larvae boring in the young canes. She also reports the larvae unusually abundant in
corn this year in her section.

PECAN

FALL 77EBWC (Tphantria cunea Drury)

Georgia 0. I* Snapp (August 19): 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.

PECMT-7T C"SE-BEARER (Acrobasis hebescella Hulst)

Georgia John B. Gill (August 2): We find that the second brood of
the pecan-nut case-bearer has not been so destructive. The first-brood larvae, appearing during the latter part of M ay
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 oc.tutred around Baconton, Ga.

] ECAN-LEAF CASE-BEARER (Acrobasis nebulella Riley)

Georgia John B, Gill (August 2): Practically all adults of the
pecan-leaf case-bearer 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 abundance of larvae at this datethe
insect will go into hibernation in great numbers. On account
of the restricted deeding 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 be spraying their orchards for the protection
of next year's crop.

HICKORY NUT WEEVIL (Belaninus caryae Horn)

Georgia John B, Gill (August 2): Pecan 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 this territory in order to look








-24O

into the pecan weevil situation. Larvae -ere found at varying depths in the soil in pecan orchards, 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 (1onellia carvella Fitch)

Georgia 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.

CITRUS

CITRUS WHITEFLY (Dialeurodes citri Ashm.)

Louisiana T. H. Jones: Infested orange leaves were received from
J. A* Wogan, New Orleans, July 28, and from J. Verburg, Hammond,
August 2. Infested privet leaves were received from Warnerton
August 3,

California California Weekly News Letter, Vol. 5, No. 16 (August 11); A
recent quarantine, known as Quarantine Order o 2, pertaining to the citrus whitefly, was placed on the cities of Sacramento,
Marysville, and Yuba City by the State Department of Agriculture.
This order @as for the purpose of preventing the shipment of
any host plants of the citrus whitefly into other parts of the
State.

reported from Peach Bottom as doing serious damage.

North Dakota R. L. Wehster (July 13): Lytta nuttalli Say is reported
from Kensal as more than usually common.

Nebraska M. H. Swenk (August 1): The gray blister beetle was
reported destroying tomatoes in gardens in Seward County
during the last week in July, and the large black blister
beetle, 22icauta corvina Le., was reported as injuring
potatoes in Knox County. The striped blister beetle,
Epicauta lemniscata Fab., was reported doing injury in
gardens in Thayer County during the second week in August.

CUTWOR S (Noctuidae)
New York Roy Latham (August 6): During the last few weeks there
has been an outbreak of Agrotis "osilon Rott. in Orient,
aA at present it is the worst ever known here. It is
doing great damage in young transplantU sprouts, cabbage,
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 4 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.

Ohio H. A. Gossard (July 25): One of the glassy cutworms was
received from Conway June 25, where it was said to be
attacking beets.

GREMi SOLDIER-BUG (Uezara hilpris Fitch)
Indiana 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 occurred. At Corydon and south to the Chio
River 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 soldierbug 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 puncture the young pods and are causing considerable injury.

SOUTHERN GREEN PLANT-BUG (Nezara virirbnla L. )

Florida F. S. Chamberlin (August 6): Pods in one field are severely
damaged by the bugs at Quincy.

POTATO

COLORADO POTATO B1EETLE (Leptinotarsa decemlineata Say)

Massachusetts A. I. Boufne (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 violated
areas.

New York 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 11 the
present time. In fields that were red with them they hate
gone into the ground after being sprayed three times. This
looks bad for next season's early crop.

Ohio H. A. Gossard (August 20): Perillus bioculatus Fab. was
received from Shelby August 1, where it was reported to bte doing very effective work in destroying the Colorado potato
beetle.

North R. L. Webster (August 3): Reports from county agents in
Dakota. northwestern counties indicate that many fields have been
severely injured this year.

Nebraska M, H. Swenk (August 1): The Colorao potato beetle was more
than ordinarily numerous in some parts of the potato growing
district bf western Nebraska, especially in Morrill County,
during July.









-243


POTATO FLEA-BEETLE (Epitrix cucumeris Harr.,)

New York M. D. Leonard (June 2): Very abundant at Hudson River State
Hospital Farm. Over 4,000 young plants were killed in one
5-acre field at Poughkeepsie.

Roy Latham (July 20): Second brood were coming in large
numbers on July 15 and browning potato fields in Suffolk County.

C. R. Crosby (August 9): Potato tubers injured by the larvae
have been received from Suffolk County.

Massachusetts A. I. Bourne (July 25): Flea-beetles on potatoes, tomatoes,
etc., are causing about the usual amount od trouble, and
do not seem to be much worse than usual except in isolated
cases.

POTATO APHID (1M.acrosiphum solanifolii Ashm.)

Massachusetts A. I2 Bourne (August 23): Aphids were very generally prevalent
at the Market Garden Field Station at Lexington on market
garden crops, particularly on tomatoes. The particular species
of aphid was not reported.

Connecticut W. E. Britton (August 7): The potato aphid was later than usual in reaching injurious abundance. It has now (August 1-4) mostly disappeared at the Station farm, Mt. Carmel, and Harden.

New York Roy Latham (July 20): Many young tomato plants are destroyed.
Potato fields were covered with this insect by July 10, but by
July 20 were controlled by parasites in Suffolk County.

W. D. Mills (August 4): Infestation has been severe, but showers have reduced the numbers of lice in Nassau County.

Indiana H. F. Dietz (July 19): 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 18): Potato feelds of Door County are infested with two principal aphids, Macrosiphum solanifolii
Ashm. and X persicae Sulz. The first, however, occupies
a secondary place in number, Myzus beint more common. Injury
is not considered serious.

POTATO LEAFHOPPER (mpoasca mali LeB.)

New York E. E. Paine (August 10): Injury is noticeable in some fields
in Chautauqua County.








-244


E. W. Pierce (August 4): This insect is causing hoppe-urnl
in fields that have not been sprayed in Ontario County.

Ohio 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 where the crop was planted in May. This
is the sixth successive year for such damage.

Ondiana J. J. Davis (August 22): The potato leafhopper is gradually
increasing its area of destruction each year.

Illinois W. P. Flint (July 26): The potato leafhopper has been very
abundant this season on potatoes, beans, and alfalfa.

Wisconsin A. A, Granovsky (August 19): Potato leafhoppers arc 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.

Iowa F. A, Fenton (July 29): 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.

TOMATO FRUIT17OR4 (Heliothis obsoleta Fab.)

New York L. A. Zehner (August 4): Severe damage to tomatoes is reported in Onondaga County.

Indiana J. J. Davis (August 22): The tomato fruitworm has been
a serious pest of tomatoes throughout the southern half of
Indiana

Illinois W. P. Flint (July 26): The corn earworm is doing some
damage to tomatoes in the southern part of the State. Full-grown
larvae were received as early as July 10.

IMPORTED CABBAGE7ORM (Pont ia rape L.)

New York Henry Bird (August): Pontia rapaewhich usually gets to
the vicinity of Rye in great numbers by mid-August from Long Islanr and New Jersey, is conspicuous by its absence at this
d&te.

G. E. Smith (August 4): The imported cabbageworm is very
plentiful in Orleans County.

E. W. Pierce (August 11): This insect is evident in most
fields and abundant in some in Ontario County.

the State, all our records on these beet"Les bearing o-,-t 'Uhis
statement, 7ith the exception of Bristol County, 71-=,
County Agent reports that rhile normally abundant they do -not
seem to be in any greater numbers than last year. I)ucting










and spraying are very generally employed in their control,
particularly in the market -trdei section in the eastern
part of the State, and seem to be Piving more or less
satisfactory results. COne factor which has been noted
regarding them, articular-y in :-iddlesex County, is that they apparently started later in the season than normally,
and this will account for the fact that they are at
present aburdant tin the stems and blosoors, w'hen under usual
circumstances their injury vould be practically over at
this period.,

New York Henry Dietrich (July): The striped cucumber-beetle has
been readily controlled with nicotine dust.

West Virginia W. E. Rumsey (Augquist 15): Leaf injury occurs as usual,
but the most serious loss is from larvae in roots. June 15 to July 15 they were most abundant in the roots. Some
recent injury has been reported.

Ohio H. A. Gossard (August 20): Inquiries regarding control of
the striped cucumber-beetle were received from many parts
of the State.

Nebraska
Nebraska M. H. Swenk (August 1): For the first time in several seasons
there has been very little injury during July by the melon
aphid. These pests began to increase early in the month
but were brought under almost complete control by the parasite
Aohidius testaceives, assisted by the ladybird beetle
diodamia convergens.
New Mexico R. Middlebrook (July 20): The melon aphid is reported from
Messilla Valley as attacking melons. Growers are now spraying, so they will get no chance, Abundance is greater as compared

FOREST AND SHADE- TRFF INS EC TS

MISCELLANFOUS FEDERS

PERIODICAL CICADA (Tibicen sentendecim 1.)

BROOD XIV (SEVENTEN-YEAR RACE)

Massachusetts A. I. Bourne (July 25): A report from lMr. Hoxie of Hyannis states
that on the north side of the Cape they were particularly numerous,
especially the last part of June and the early part of July, but
as far as the injury to trees of economic value 'as concerned, the
damage was very slight indeed.

Ohio H. A. Gossard (July 25): The brood of the 17-year locust appeared
perhaps a little later than the average season and continued until
early July. From the large numoer of reports now in my nbes I
judge that the brood was more numerous + r in 1P06 ani tVat considerably more damage was done to youn: or Lads an: t et
trees. Many young orchards were repcrted :o us 'Ireat ::d or
ruined." VThile I have not had time to ':e.: on fuv on ae infested territory, I think they appeared in considerable numbers in
neighborhoods where they were comparatively sparse 17 years ago.
P IA

Indiana J. J. Davis (August 20): Observed injury to oaks and hickories
north of Corydon to Corydon Junction, the injury being especially common near-Corydon Junction. N. I. Clunie, the County Agricultural Agent; writes that the cicadas were abundant in the northcentral part of Harrison County and also in the southeastern part,
mentioning especially the vicinity of Laconia. He reports scre
damage to young orchards.

GIPSY !OTH (Porthetria dispar L.)

Massachusetts A. I. Bourne (July 25): In northern 7orcester County, Trr. Calkins
reports the gipsy moth as very scarce and as doing less damage
than the apple tent caterpillar. Mr. Hoxie of East Sandwich,
which is on the Cape, reports that caterpillars do not appear to
be anywhere nearly as numerous as last year. Mr. Farrar, of
M1iddlesex 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.

BROWN-TAIL MOTH (Euproctis chrysorrhoea L.)

Massachusetts A. I. Bourne (July 25): Mr. Fiske of Lunenburg states that in
his orchard the damage was practicaly nil and the brown-tails
were virtually extinct. The same condition prevails in northern
WVorcester County, where this season Mr. Calkins, reports practically no brown-tails seen this year. Mr. Farrar, of 11iddlesex
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.

EL. SPANWO~ M (Ennomos 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.

~7HITE-MARKED TUSSOCK i,,OTH (Hemerocamoa leucostipa S. & A.)

New York V. E. Peterson (July): Spraying for the caterpillar of the tussock
moth, which has infested thie trees of Buffalo in great numbers, hss just been finished. Conditions have oeen worse this year than for
some years previous.

R. E. Horsey (July 17): The :hite-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.

BG7XO E (Thyridopteryx ephemeraeformis 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 Improveent Society has requested the cooperation of this office in a control
campaign next season.

received from many points in Ohio.

T. H. Parks (August 13): Unusual summer reports have been received of the presence of this insect in central and southern
counties. Trees attacked are mostly evergreens, including arborvitae, but it is also present on fruit trees.

E. IV. Mendenhall (August 8): The bagworm is doing great damage
to trees, especially evergreen trees and shrubbery, in the vicinity
of Cincinnati, Ohio.

Indiana J. J. Davis (August 22): Numerous reports have come from Terre
Haute south to the Ohio River, i.e., a little more than the southern
third of Indiana. The species occurs princippally on arborvitae
and other conifers, but some injury is done to deciduous shade
trees.

Missouri L. Baseman: Numerous complaints continue to come in about the
bagworms, especially on evergreens%

Texas F. C. Bishopp (August 25): Bagworms have been very abundant on
arborvitae and cedars in certain sections of Dallas County. Some
trees have been completely defoliated by the pest.

New York R- E.'Horsey (J0'uly 17): The elm leaf-iner is rather more common
than usual. S ome small trees with their leaves badl.1y disfj.:ure d
are to be found in igadPrk


EURFFAN FUT SCI LE (Gossvparia snuria !.odeer)

New York R. E. Horsey (July 17): The elm bark-l ouse w-as sp-rayed on July 6
and 12 while moving. Very little occurs in IFighland Park and on
streets, but a nt;*a infestation has been found in street trees in
a nearby sec-tion of the ci-ty.

New Jersey R. B. Lott (Au,.st 21): Th is scalc has been noted as very plentiful on a row,, of eLrrs at Bo-Lnd 7-rook.

Columbus, Dayton, Akron, S!7L em, u-;d Tiffin.

FLATHEIDED BORFJPq S

Texas F. C. Bishopp (August 25): Borers T hich have been determined by
R. A. St. George as Chrvsobothris sn. 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 The oriental sycamores which are
now being tried as shade trees in this section are infested equally









as badly as t..e native. If it were not for the continual worming
of the trees oy the city forestry department these borers would
bring about the destruction of practically all trees set last spring.
A goodly namoer of borers were also -resent in t-o and three-yearold trees, but they seem better able to withstand the attack.

LUK LEAF-BEETL (Galerucella luteola IHuell.) Massachusetts A. I. Bourne (July 25): One or two cases of infestation of the
elm leaf-beetle on elms immediately around 1mherst have been observed 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 throuighcut the State have been
oroulgrt to our attention, however. The pest is a--prently beginning gradually to "come back" after a lapse of several years.

Connecticut Philip Gar-ran (August 23): These beetles are severely d raging
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 of the trees, while a number ,were still feeding. The first of the month wie sprayed about 30 trees here.
This insect is slowly spreading but where spraying is thoroughly done can be kept under control. The greatest proolemn is traffic and the objection of people to having their houses spotted by the
spray material.

ELM BORER (Sarerda tridentata Oliv.)

Nebraska M. H. Swenk (August 1): Elm trees were reported injured by the
elm borer.

ELM APHID (Yyzocallis ulmifolii :ionell)

Station as K. ulnifolii. The leaves were considerably discolored
and spraying with heavy oil enuisions w-as carried out.

HIrWORY

HICKORY BARK-SEETLF (Sco-us quadrisoinosus Say)

New York Henry Bird (August): This insect, 'hich 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 1): In western iNebraska re-orts of injury to
cottonwood trees by the vagabond gall-louse were received.

OYSTERESHELL SCPLE (eidosahes ulmi L.)

Indiana H. F. Dietz (July 18): The light-brown form of oyster-shell scale
began laying eggs on July 6. 7The second brood should appear within
the next tw:o 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-;hell scale, puolishd- by Glenn in the Journal of Economic
Entomology for April, 1921, should be followed, i. e., the liZhtbrown form,which is two-brooded and which lives on Carolina poplar but cannot maintain itself on apple; the arole form, .iich is likewise two-brooded and lives on apple but cannot live on Carolina
poplar; and the grat-bown form, which is single-brooded but cannot
maintain itself on apple, at least in this State.

PALE TUSSOCK HOTH (Halisidota 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 scripta 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 1): In western Nebraska reports of injury to
cottonwood trees by the cottonwood leaf-beetle were received.
tAugust 1): injury to the cottonyrood trees in the City Park at Callaway, Custer County, by the cottonwood leaf-beetle was complained of during early August.
