OUTSTANDING ENTOVOLOCICPL FEATURES FOR PAY,1922.


The Hessian fly situation as a whole is most encouraging. Reports
from Indiana, Tllinois, Missouri, and California indicate that practically
no damage will be done. Central Tennessee alone seems to be seriously infested.

The chinch bug is becoming more threateningly numerous throughout the
East-Central States, and is again appearing in the Ncrth-Central States. The first authentic specimens that have been taken in 10 years are reported from Vinnesota, and the pest is again appearing in southeastern Nebraska.

The pale western cutworm promises as serious an infestation throughout its North Dakota and Montana range as occurred last year.

The heavy floods in the Ohio and Mississippi River Valleys have developed an ecological condition favorable to the abnormai increase of certain lepidopterous larvae. Indiana reports that the black cutworm is f-esred in the overflowed Wabash River Valley, and Louisiana reports that theIr4y worm has already appeared very serious in overflowed regions in that State.

An unconfirmed report of an outbreak of the true army worm in upper Pennsylvania has been received.

Throughout the Middle Atl&ntic States and as far west as Indiana reports are being received of an unusual abundance of the brassy flea-beetle.

The clover leaf weevil is not as serious as was anticipated early in
the spri ng. This insect is being controlled over -art of its range by the common fungous disease Entomophthora o It is much more
abundant than usual, however, over the eastern ha2'f of Kansas.

The various fruit aphids are not as severely abundant as usual over the greater part of the apple-growing sections of the eastern United States. In the New England and M.-iddle Atlantic States the la frosts checked these insects with the possible exception of the rosy siml 4'pid. In the Mississippi River Vulley, however, very severe outbreaks are reported from Minnesota, Iowa, and Arkansas.

Tent caterpillars are reported throughout the New England and Middle Atlantic States as unusually abundant.

The apparent increase of the San Jose Scale over much of the eastern United States, reported last year, is being confirmed by reports received this month.

Pears and plums are being seriously damaged in Oregon and California by the pear thrips.

The blackhead cranberry worm is appearing so numerous in the central
counties of Wisconsin that control flooding is being practised.

Hopperburn of a typical nature associated with the potato leafhopper is reported from Louisiana, this beihg much south of the general range of this trouble.

About 3 years ago specimens of a small nitidulid were sent to the
National Museum from Youngstown, N. Y., for determination. These proved to be the European Heterostomus pulicarius L., a species apparently of but* little economic importance in Europe, where it is recorded as feeding on the pollen of Linaria. In 1920 Mr. H. Notman described what Mr. Schwarz considers as this species under the name of H. merdelloides, from Schoharie, New York. In 1921, 11r. H. Morrison collected specimens of this same beetle in Arnold Arboretum at Boston. In this number of the Bulletin is a report by Dr. E. P. Felt that this insect is seriously damaging strawberries in Columbia County, and is distributed over Saratoga, Albany, Niagara, and Schoharie Counties, New York. The damage is done by the 1dult beetles feeding at the base of young blossoms and producing "nubbins"
or entirely destroying the fruit.

An infestation of approximately 1,000 acres of peas in the San Joaquin Valley in California by the pea aphid was reported early this month. It
that time the infestation was not serious.

Reports from the greater part of the cotton belt indicate that there is an unusually large number of boll weevils on small cotton for this time of the year, and on May 24 weevils were more numerous in the vicinity of Tallulah, La., than in any previous year of which records are available.

Turkey gnats are unusually abundant in parts of Nebraska and Pissouri where they are so seriously attacking poultry that chickens and even mature fowls are being killed.

One of the most interesting developments of the month has been the determination of a beetle, collected in a Connecticut nursery during the past two years, as Anomala orientalis"trh,the anomala which occasioned so much concern in Hawaii aoout 10 years ago. The insect is a native of Japan and was probably introduced into Hawaii before 1908 in soil on the roots of imported plants from Japan. In 1908, Dr. Lyon, then working, with the Hawaiian Sugar Planters Association observed large numbers of these larvae at the base of cane plants but mistook them for the Japanese
beetle of Hawaii (Adoretus tenuimaculatus Waterh.). In 1912 Dr. A. Spear, in studying the fungous diseases of insects affectinq sugar cane in Hawaii, collected a number of these larvae and turned then over to M!r. F. Puir, who recognized them as a species new to the Islands. In June of that year Mr. Muir visited the infested fields and collected adults. The pest, though infesting but a small area, was extremely destructive, and the
Hawaiian Sugar Planters Association detailed a specialist to proceed to the Orient and obtain parasites for the control of this pest. This work was so successful that one of the parasites (Scolia maniac Ashm.) was. established between the years of 1914 and 1916, and by 1919 it had so
thoroughly controlled this pest that from an area where, in 1917, 3,500, anomala grubs were collected only 4 grubs were found by most diligent, search. The parasite has extended its range beyond the area infested by the anomala and is now infesting the Japanese beetle of Hawaii. That the anomala is established in Connecticut seems evident, as opecimens have been collected in the same nursery two successive years.








INSECT PEST SURVEY BULLETIN

Vol. 2 June 1, 1922 No. 3

CEREAL AND FORAGE-CROP INSECTS

WHEAT

HESSIAN FLY (Phytophaga destructor Say)

Indiana J. J. Davis (Insect Notes No. 10, May 17). "The Hessian fly
will do very little injury this spring in Indiana."

Illinois W. P. Flint (Mlay 1S). "Heavy tains at time of emergence of
the adults have reduced the spring brood so that practically
no damage will occur this season."

Missouri A. C. Burrill (May 4). %iMuch less abundant this year than
usuall September brood has not yet emerged; other broods
evidently perished.

Tennessee G. G. Ainslie (May-15):~ "In central Tennessee (Maury County)
the spring brood of the Hessian fly had about half pupgted during the last week in April. A few days later Ue larvae
were reversing themselves in the puparia and since then some
flies have emerged. The infestation throughout central
Tennessee is unusually heavy for tho spring generation. Exarnination of samples by Mr. Larrimer show 23 per cent of culms aind
93 per cent of the plants infested. A secondary or suijlementary spring brood of the fly in this section seems certain."

California C. M. Packard (May 1). "The Hessian fly is not injuring wheat a.s seriously as usual in the Montezuma Hills wheat-groaing
section this year. This seems to be due to cold windy weather
in March and early April when flies were emerging from the
stubble, and excessive moisture has enabled wheat to outgrow
fly injury. "

GRASSHOPPERS (Acridiidae)

Wisconsin S.B. Flacker (May 23). "First and second instar nymphs are appearing in the northeastern part of this State, east of a
line extending from Iron to Portage Counties and north of
Wausharo and Door Counties."

MARCH FLIES (Bibio aspp.)

Ida.o R. A. M ttkowski (May 12). 'uring the past two weeks reports
have been received (with specimens) of scinus amaae to winter
wheat. The fly Bibio Hirtus was reared fr 1 this mo :al.
Thits fly is exceedingly abundant in Latah C-cxlty r
but this is the first time that any specafr, damage how bn
attributed to it. The pest is reported as feeding on tne
roots of wheat plants.a






66
WESTERN WFEAT-STA MADI (GGO cerealis Gill.)

Nebraska M. H. SWenk (May 15). "Early in May the wheat fields in
Scottsbluff Ccunty developed an infestation of the western
wheat-stem maggot. The maggots were full grown and preparing to pupate on May 9. This infestation coincides
seasonally with the infestation that was found in Colorado
in 1903, at the time of the original discovery of this pest# and is considerably later than the infestation that occurred
last year in lYorrill County in this State, when the adult flies emerged early in May. It seers possible, therefore,
that this pest has three generations in the wheat before
harvest: The first in the middle of April, the second in the middle of May, and the third in the latter part of June
and in early July."

CHINCH BUG (Blissus leucoaterus Say)

Ohio T. H. Parks (May 20). "Greater damage is anticipated from
chinch bugs in the northwestern quarter of Ohio than for several years. Bugs were flying in considerable numbers
early in May."

Indiana J. J. Davis (May 15). "As anticipated, the chinch bug is
showing up in many sections of the State. Reports of rather
heavy infestations of adult bugs in grain fields have already
been received. There was no conspicuous flight of chinch
bugs st La79yette previous to May 1, on which date we observed
a considerable flight, and on the following Thursday (May 4)
there was a very heavy flight of bugs which seems to have
been rather general and widespread."

Illinois W. P. Flint (May 18). "Adults more abundant than last year in
most counties in central Illinois and slightly to moderately more abundant in southern Illinois. Damage will occur over
at least twc-thirds of the State. Eggs just being deposited;
no young bugs reported even in extreme southern part of State."

Minnesota A. G. Ruggles (May 1). "Of the cereal insects probably the
most important is a find of chinch Wugs. These were taken in the northern part of the State the first of the month and are the first authentic specimens we have taken in Minnesota
for 10 years."

Nebraska M. H. Swenk (May 15). "The chinch bug was noted s active in
the wheat fields of Thayer County on April 12."

Missouri A* C. Burrill (May 3). "Heavy infestation in immediate vicinity
of straw-stack in Bates County. Bugs dispersing on foot in
all directions; no flight." (Ray 5), "General mating earlier
than last year in Carroll and Bates Counties." (May 25). "To
date we have reports of chinch bug abundance from Callaway,
Monroe, Montgomery, Schuyler, Bates, and St. Clair Counties."






67

GREEN BUG (Toxoptera graminum Rond.)

Texas E. E. Russell (May 8). "Several fields in Floyd and Foard Counties
were found to be quite severely injureJ by the green bug. One
field consisting of 220 a:r ns in F_ oy Couty was a total loss.
This particular in-lt t.Io s sup ...ed tc have started from
volunteer grain rcr a ur:ta:. e 'ei-es. Thpse local
outbreaks are the only r -' Dr.s ci' injury whicn have reached us from northern Texas thi' 3 er, and dPage has ceased owing to
control of pest by its natural enemies."

JOINTWORM (Harmolita tritici Fitch)

Illinois W. P1 Flint (May 18). "Ovipositing in large numbers through
central Illinois during week of May 8, particularly abundant
in western Illinois."

ARM1Y CUTWORM (Chorizagrotis auxiliaries Grote)

Montana W. C. Cook (May 5). "Army cutworms quite abundant. About half
grown at Fresno, Kremlin, and Laredo. Much later than usual in
appearance, no evidence of migration as yet."

PALE WESTERN CUTWORM (Porosarotis orthoeonia Morr.) North
Dakota R. L. Webster (May 12). "This insect is appearing fully as bad as
last year. The infestation seems to be most severe in Golden Valley County, although injury extends eastward and southward.
A tachinid parasite was noticed in numbers."

Montana W. Cd. Cook (May 5). "This insect appeared for the first time
this- season near Laredo." (May 15). "At the northern Montana
substation, these lar-vae are spa.rently as abundant as last
year, though somewhat smaller than they were at this time in 1921."

.BLACK CUTWORM (agrotis ypsilon Rott.)

Indiana J. J. Davis (May 15). "The overflow worm, so called because it
follows the late overflows of thbe Wabash River and its tributaries in southwestern Indiana, is likely to be very abundant
this spring, and probably more destructive than in previous
year,because of a larger acreage in corn. Twenty thousand
acres of wheat was destroyed by water overflow in Gibson County which will probably be planted to corn, making a total of 60,000
acres in this one county which is subject to overflow worm attack.
This same species seems to follow 'late overflows wherever they
occur."

FALL ASMY WORM (Lanhvygma frugiperda S. & A.)

Loua&iana T. H. Jones (May 17). "Because of the large amount of territory
overflowed in this State, a number of requests have already been
received for information on preventive measures aga-irt grass
worms. Injury by grass worms (usually LaChvma fruciperda) is
common to plants planted on overflow land."











LESSER 11IGRATORY GRASSHOPPER (K e atlanis Riley)

Lontana A. L. Strand (May 19). "The eggs of this grasshopper are reported to be hatching in Yellowstone County."

UPLAND CORN VIiR7opV (Velanotus pilosue Blatch.)

Nebraska E. H. Swenk (May 15). "The upland corn wireworm was found
eating off the roots of wheat and barley and killing out
large patches in the field in Adars County on }fay 8. Wireworms, presumably of the same species, were responsible for
the killing out of the young alfalfa sown in Clay County fields last fall and resown this spring. The spring sowing had been
practically destroyed by F.ay 9.'

GREAT PLAINS FALSE WIREVOR (Eleodee onac4 Say)

Nebraska 11. H. Swenk (May 15). "In addition to the losses of wheat in
Deuel County due to injuries by the Great Plains false wireworm, reported last month, similar injuries have since developed
in Scottsbluff County. In one 160-acre field of winter wheat
about 70 acres had been destroyed by May 4#"



ARMY WORM (Cirphis uninuncta Haw.)

New York C. R. Crosby (April 26). "First adults of the season collected
at trap lantern on this date."

Pennsyl- w. R. Walton (May 26). "County agent located at Erie, Pa.,
vania reports, under date of May 24, the presence of a local outbreak of the true army worm. We are endeavoring to confirm
this report by sending one of our corn borer men to Erie."
V'EWLOR 'S
Tennessee C. G. Ainslie (May 15). "Larvae of Crambus Mutabilis Clem.
have been taken in considerable numbers from corn on new and
sod land. This is the only species that has been found
attacking corn thus far this year. Moths of the following
species were first observed on the dates given! Crambus
praefectellus Zinck., April 15; C. laSueatelluo Clem., May 3, C. mutabilis, May 12; all observations at or near Knoxville.
Larvae of the burrowing webworms of at least two species,
probably Acrolophue popeanellus Clem. and A. arcanellus Clem.,
have been found around Knoxville. A young corn plant attacked by either is usually completely consumed. The burrowing webworms can usually be distinguished from the crarbid larvae by their burrows being open, while the latter close their burrows
at the surface of the ground with a valve."









69

FLEA4BEETLES (Halticinae)

(aryland E. N. Cory (ay 13). "Chaetocnema nulicaria Helsh. is doirp
serious damage to corn in Montgomery and Hartford Coun-, P "

Indiana J. J. Davis (MAay 15). "A small black flea-beetle (species not
determined) was damaging sweet corn near Terre Haute on May 9,
and apparently it had been attacking the plants for several
days before they were observed. The injury was quite serious
and general in that section."

Tennessee G. G. Ainslie (ray 15). "Corn planting has been delayed o ve.:
the whole eastern half of the State by the continued rainfall.
In some early planted fields on new or sod land near Knoxville
flea-beetles (Chaetocnema nulicaria) were found so abundant that some plants had evidently been killed by the. There
were often 30 of the beetles on a plant with but two or three
leaves.

Missouri A. C. Burrill (May 24). "Corn seriously damaged in Marion, and
Ralls Counties. Farmers fear flea-beetles will be worse than
chinch bugs."

Arizona Correction: In the last number of the Survey Bulletin the note
on Phvllotreta pusilla Horn,page 38, should have been under
Chaetocnema ectyna Horn.

CLOVER

CLOVER-LEAF WEEVIL (HWpera Punctata Fab.)

Indiana J. J. Davis (April 15). "Reported as injuring clover in southern
Indiana within the past week." (May 15). "Not as many reports
were received as anticipated, which was probably due to the
fact that in the low areas they were destroyed by the overflow
and in other sections of the State clover made such a heavy
growth that the injury was not noticeable, even where the
weevil larvae were present.'

Iowa Fred D. Butcher (May 17). "The clover-leaf weevil has appealed
in practically the same areas as reported last year; only occasional fields are seriously damaged at this time. A
fungous is attacking the weevil and is controlling it very
successfully, especially in the southeastern part of the State. In the south-central part the disease is present
in nearly all fields, but not sufficiently epidemic to control
the weevil."

Missouri A. C. Burrill (May 11). "This insect is less abundant than
usual, probably due to fungous disease; in fact, damage has
practically ceased."







70
Illinois S. C. Chandler (April 27). "At the start of the season considerable feeding was done and severe injury anticipated.
The fungous disease of this insect was becoming prevalent
during the week ending April 29, and clover is now rE-iCCering
with no prospect of further injury. The first pupas was
observed by myself and 11r. B. W. Cartwright on April 24 at
Centralia. The first adult was observed April 26 at Fairfield."

Kansas F. G. Kelly (May 6). "This insect is much more abundant than
in previous years. The larvae are now from one-half to twothirds grown. It is quite generally distributed over the
eastern half of the State."

LESSER CLOVFR-LEAF VT EEL (Phvtonorcus niprircstris Fab.)

Ohio T. H. Parks (Oay 20). "This insect continues to be the worst
pest of red clover in western Ohio. Larvae have been hatching since May 1. The clover promises to make a good tonnage with
the usual number of insects present. The area of serious
infestation has been extended southward across the State and
now includes the area about Columbus and 'arion."

Illinois W. P. Flint (Hay 18). "Weevils left hibernation very late,
They are not as abundant in fields as during the season of
1921. Very small larvae and eggs were observed on this date."

CLOVER MITE (Brvobia nraetiosa Koch)

Oregon A. L. Lovett (M ay 9). "This mite was observed for the first
time in this locality. Small heavily infested areas were
found in the college experimental plates. Weather has been
cold and rainy up to within the past few days."







71

FRUIT INSECTS

APPLE

APPLE APHID (Ahis romi DeGe3r)

Massachusetts A. I. Bourne (May 12). gThis insect is much less numerous
than usual, probably due to very cold weather from April 20
to April 22."

New York C. R. Crosby and assistants. "Late in April this species
was in conspicuous numbers in Niagara, Monroe, and Wyoming
Counties. The very cold weather, however, seems to have
materially reduced their number, as they were reported
during the first half of May as very scarce throughout the
greater part of the State."

Pennsylvania S. W. Frost (May 13). "This species was not as prevalent
as the other species of aphids on apples this year."

Iowa F. D. Butcher (May 17). "The green apple aphid is still
causing damage in counties in which no efforts were made to
control it. Orchards in Madison County show the aphid
present in large numbers. No general migration to oats up
to this date."

Arkansas Dwight 1#i1 (May 22). "Much more abundant than usual and
generally distributed in nearly all orchards in the northwestern
corner of the State. This is the first outbreak occurring
in this region since 1918 and has been quite severe,
considerably checking the growth of young trees."

APPLE-GRAIN APHID (Rhoralosiu prunifoliap Fitch)

Pennsylvania S. W. FroSt (May 13). "This species has been very abundant
this. spring."

New York C. R, Crosby and assistants. "Th3se insects were qaite
abundant during the third week in April but heavy freezes
h.ve.reduced them to a negligible factor."

Illinois C. P. Compton (April). "Apple trees are generally infested
with aphids in the northern part of the State. In some sections
the infestation is heavy,"

Wisconsin S. B. Fracker (May 20). "This insect was present in large
numbers throughout the State as the buds were opening. It
has been practically eradicated by Syrphidae and Coccinellidae."











tMinne-sota A. G. Ruggles (May 17). "Late in April many green apple
aphids were found on apples around Lake Minnetonka. They
hid just hatched and were very -numerous."

Missouri A, C, Burrill (May 11). *Earlier in the season these insects
were much more numerous than usual in Chariton County. Heavy
rains are said to have cleaned them up."

Kansas E. G. Kelly (May 6). *This insect began to appear in considerable
numbers by April 2. Spraying with nicotine sulphate has not
been very effective."

Arkansas vight Islwy (April 29). 'There has been an outbreak of the
green apple aphid and the European grain aphid over the fruit
regions of northwestern Arkansas. The injury is not severe but the insects are, apparently, present in practically all orchards. This is the first aphid outbreak on apples since
I came to Arkansas in the spring of 1918."

ROSY APPLE APHID (AnrArhis rospus Baker)

Connecticut W. E, Britton (May 23). "This insect was observed as causing
some curling of leaves at Mt. Carmel. Syrphid larvae are
present."

New York C. R, Crosby and assistants. "During the last week in April
hatching was quite general over the fruit growing sections of New York. This aphid seems to have resisted freezing weather fairlyWell and during the first half of May consiaerable leaf
c.rling was observed."

Pennsylvania S, W. Frost (May 13). "During the first part of April counts
of the tbreeo-species of aphid on apple showed a very small
percentage of the rosy apple aphid. Since that time this insect
has increased in numbers and orchards in Adrms Cotnty, whare
nicotine was not used in delayed-dormant spray, show bad
infestation of this aphid. A higher percentage is evident
this year than has been noticed for five years."

Maryland J. A. Hyslop (May 20). "The rosy apple aphid is much more
numerous in the southern part of Montgomery Covnty than last year. Considerable curling of leaves is now evident in some
unsprayed orchards."

Delaware J. F. Adams (May). "Serious injury by this species is reported
from several localities."








73

.CODLING MOTH (Carpocausa p0monS.lla L.)

New York C. Ro Crosby and assistants. "Mr. G. E. Smith reports that in
Orleans County very littl pupaticn had taken place up to May
2. Of 33 specimens collectcid in one orchard, 32 were larvae
and but one a pupa. By May 13 not over 12 per cent had pupated
and by May 1Z the larvae were still very numerous and
comparatively few had pupated. Mr. D. Rupert makes a very
similar report from Wayne County."

Indiana J. J. Davis. "The first emergence of the codling moth was
observed on May 3 at Clayton and at LaFayette on May 9. There
are now. special indications of an unusual abundance of this
insectt"

Illinois W. P. Flint (May 18). "Emergence of adults started in southern
Illinois on iay 1; in north-central Illinois, on May 14. But
few worms are to be found in orchards on this date."

Arkansas lDwight Isaly (April 29). "First record of emergence at Fayetteville
on April 20. a

Washington E. J. Newcomer (Hay 15). "The minimum winter temperature has
ranged from 8 to 10 degrees below zero, resulting in about 4 per cent winter kill. No moths are flying up to this date."

CLIMBING CUT OBRS (Species not determined)

Washington E. J. Newcomer (May 15). "Probably two or three hundred acres
in the Yakima Valley have been protected by putting a bani of
axle grease around th3 trunk of each tree. This was done by the
growers against the advice of horticulturists who feared injury
to the tre3s from the gretse. A few growers used cotton bands with success. These climbing cutworms are much more abundant
than usual."

SFRUIT-TREE LEAF-ROLLER (Cacoecia arevrospila Walk.)

New York C. R. Crosby and assistants. "This insect is appearing in considerable numbers in Orleans, Monroe, and Chautauqua Counties.
They are comparatively scarce throughout the remain.da rof the
fruit section. Approximately two-thirds of the eggs had hatched by May 6 in Niagara County, according to Mr. L. F.
Strickland, while egg hatching had just started in Orleans
County on May 8."








74
Oregon D. B. Fulton (April 25). "This insect is decidedly on the decrease.
and is no longer a serious pest in the LaGrande region. Spraying
with miscible oil has been practised in this region for the past
four years."

LEAF CRUMPLER (Mineo]a indigenella Zell.)

South
Dakota H. C. Severin (April 25). "This insect is quite a general pest on
apples this year."

CIGAR CASE-BEARER (Coleophora fletcherella Fern.)

New York C. R. Crosby and assistants. "This insect is reported as numerous
from Orleans, Wayne, Nassau, and Monroe Counties and present in
moderate numbers in Genesie, Ulster, Seneca, Onondaga, and
Chautauaua Counties. Very few are to be found in well sprayed
orchards."

Missouri A. C. Burrill (May 12). "So numerous in parts of Chariton County
that they are girdling large twigs."

BUD MIOTH (Tmetocara ocellana Schiff.)

Mas-zachusetts H. T. Fernald (April 19). "Mr. H. A. Mostrom, of the Essex County
Agricultural School, reports that this insect is very steadily
increasing and is now prevalent enough to be considered as a
general pest in Essex County."

Connecticut M. P. Zappe (May 24). "This insect is noticeably less abundant
about Milford than it was last year."

New York C. R. Crosby and assistants report this insect as very numerous
in Nassau County and on the ine~-ase in Onondaga, Orleans,
Genesee, and Wayne Counties an'i that a few were reported from
Monroe, Columbia, Niagara, Ulster, Seneca, and Rockland Counties."

Oregon A. L. Lovtt (May 10), "This insect is much above the average
in abundance and injury this year. The damage is usually confined to stone fruits, but this year all fruits show heavy infestation."

GREEN FRUITWORM (Xylina antennata Walk.)

New York C. R. Crosby and assistants report this insect as quite abundant
in Wayne and Chautaugua Counties about the middle of May.

Pennsylvania S. W. Frost (May 13). "Larvae rather abundant this spring. They
were easily killed with lime-nicotine dust, Niagara D-11."








75
TENT CATERPILLAR (Malacosoma americana Fhb.)

Massachusetts H. T. Fernald. "Tent caterpillars seem to be very much more abundant than last year. In Essex County hatching started about April 10 and nests were pretty well filled by May 10. They were also reported as seriously abundant in Lincoln and Worcester Counties. The present outbreak seems to be the worst that has occurred in this State in years."

Connecticut D. A. Porter (May 24). "This insect is much rcra abundant
than last year and is, apparently on the increase in the vicinity of Wallingford. hany of the nests have been deserted and the spinning of cocoons is just beginning."

New York C. R. Crosby and assistants. "Tent caterpillars have
appeared in considerable numbers in Dutchess, Orange, Rockland, Ulster,and Wayne Counties. In Wayne County the nests are increasingly noticeable, especially where poor spraying has been carried on."

New Jersey E. B. Weiss (May 16). "This insect is four or five times
as numerous as during normal years. A general outbrak is occurring over the entire State. Mr. F. L. Rook reports that 90 per cent of all the wild cherry tress are more or less. defoliated in the southern part of the State."

Delaware C. 0. Houghton (May 10). "This species is more abundant than
usual this year. Caterpillars are now migrating, preparing for spinning up. The accumulated excess temperature at Newark is approximately 350 degrees."

Maryland A. L. Quaintance (May 25). "This insect seems to be unusually

Oregon A. L. Lovett (May 17). "Malacosoma pluvialis Dyar. is
excessively abundant in southern Oregon and decidedly more
numerous tham it has been since 1912 in the Willawette Valley.
It is not uncommon to observe in the prune orchards of the
Willamette Valley an average of five tents to the tr.ee The tents are also conspicuous on wild roses along highways and
fence rows."

SPRING CANKERWORM (Paleacrita vernata- P-k)

New York C. R. Crosby and assistants. "This insect is plentiful in the
regions infested last year. Eggs started hatching about
May 6 in Orleans County and had practically all b chd by
May 12 in Niagara County. They are also reported from Wayne
and Orleans Counties."

Delaware J. F. Adams (April 30). "Larvae observed attacking apple at
Milford on this date."

Iowa F. D. Butcher (May 17). "Cankerworms in Wapello, Henry,
Jefferson,and Lee Counties are causing a good deal of damage,
especially in young orchards which were not sprayed, Owing
to frequent rains in Lee County, a few of the orchards which
were well sprayed are still being attacked."

Minne.sota A. G. Ruggles (May 17). "Carnkerworms, both spring and fall
species, are very numerous with us at this time."

Missonri A. C. Burrill (May 12). "Much less numerous than last year in
Chariton County."

species, are very numerous with us at this time."








77
TARNISHED PLANT-BUG (Lvyus pratensis L.)

Pennsylvania S. W. Frost (May 13). "Very abundant in apple orchards in
Adaits County."

Indiana J. J. Davis (May 15). "What we believe to be the tarnished
plant-bug was reported as killing apple buds at Greenfield
on April 19. Specivens were not furnished, but the
description and character of the injury agreed very well
for the tarnished plant-bug."

FALSE APPLE RED BUG (Lyidea mndax Reut.)

Connecticut D. A, Porter (May 3). "First hatching of eggs observed
on this date, both in insectary and in field at Wallingford."

New York C. R. Crosby and assistants. "Second-stage nymphs were
predominating on May 13 in Green County, while eggs were
just.hatching on this date in Onondaga Coun'ty."

Pennsylvania S. W. Frost (May 13). "Nymphs of this species are numerasO
this spring. The foliage shows an abundance of spotting by
this insect."

SSAN JOSE SCALE (Aspidiotus perniciosus Comst.)

New York C. R. Crosby and assistants report that this insect is,
apparently, on the increase in Wayne and Orleans Counties
while it is comparatively scarce in Ulster, Orange, and
Columbia Counties,"

Indiana H. F. Dietz (May 1). "A trip through the southern end of the
State shows the San Jose scale 'coming back strong' unless
through control measures are carriecl out. At Mitchell some
young trees were killed in a single year."













J. J. Davis (May 15). "In addition to other factors, the
wet spring has prevented as thorough spraying with the otrrant
sprays as was necessary to chack the increasing numbers of this scale insect. As a result, this insect now threatens
to destroy many trees and possibly many orchards unless
checked before the next dormant spray can be applied. We are, therefore, urging a summer strength of lime-sulphur to assist in checking the increase of this scale until the next dormant
spray can be applied."

Illinois ., P. Flint (May 18). "There is a higher percentage of
parasitism of this sale than has prevailed for several seasons."

Missouri A. C, Burrill (May 13). "This insect is much worse than lsual
in Charitr.n County, where trees are dying from infestation.
It was controlled in all sprayed orchards where spraying was carried on every year. We will try scalicide while the trees
are in fruit."

OYSTER -SHELL SCALE _Leridosaphes ulmi L.)

Massachusetts H. T. Fernald, "Mr. H. A. Mostrom reports that this insect
is becoming more serious than the San Jose scale in Essex
County."

New York C. R. Crosby and assistants report that this insect is rather
serious in some parts of Columbia, Wyoming, Orange, Onondaga,
Wajyne, Ulster, and Orleans Counties."

Indiana J. J. Davis (May 17). "The oyster-shell scale is hatching at
LaFayette. 7e are recommending spraying about ten days
or two weeks after the young begin to hatch, usipg whale-oil
or fish-oil soap, 1 pound dissolved in 5 gallons of water to which is added 1 ounce of nicotine-sulphate, spraying
thoroughly so as to cover all twigs and parts of the twigs.
In very severe infestations we are recommending a second
spraying eight days after the first."

H. V. Dietz (May 23). "The oyster-shell scale has been
hatching and the records for the three forms at Indianapolis, as outlined by Glenn, are as follows: Light brown form began
hatching on May 1 to 12; apple form, sent from Hamzrond,
began hatching on May 10 to 21; the grape form began hatching
on May 20."

South
Dakota H. C. Severin (April 15). "This insect is one of our most
serious fruit-tree pests."

this region. At the present time they are unusually abundant on grape foliage and feeding sparingly from the uppar surface
of the leaves. Grape blossoms not yet open. The crop prospect has been injured seriously by late frosts, and
spraying will be necessary in order to save the remaining
fruit from infestation by the curculio."

Now York C. R. Crosby and assistants. "Adults were first observed in
Nassau C~ounty on May 10.1'

Delaware C.oO0. Hou4~hton (Way 10). "The common asparagus beetle is
more co,-xoa than u:;ue1l at Ne-,rar%. The iirst spec.-men of
the 12-~Ubeetle was cU P.'vod on this data. They are
much less nt .erous than the common nspqragus beetle."

Maryland J. A. Hyslp f.Vay 1). "The first, adult of the season observed

BEANS

MEXICAN BEAN BEETLE (_Enilachna corrurta DIuls.)

New Mexico F. H. Chittenden (Monthly Letter Bureau of Entomology No. 96).
"Ur. J. E. Graf, reports that in the Estancia Valley in New
11exico hibernating beetles were found several riles from any
previous bean plantings and high in the hills in the partially
wooded sections of the Valley.. It is apparent that hibernating in woodlands is characteristic of this beetle.
Evidently a certain amount of woodland is necessary to provide
suitable hibernating quarters and the beetles, have failed to
hibernate successfully when extending their range eastward from the Rocky Vountain foothills. In the Fast, which is comparatively heavily wooded, no limitation of this nature
will prevail and the beetle will probably be able tc extend its range over the entire territory east of the Y'ississippi
River.'

BEAN LEAF-BEETLE (Cerotora trifurcata Foerst.)

Arkansas Dwight Isily (April 27). "The first record of this beetle
made today. Leaves stripped locally in a few instances."
(I'ay 22). "Bean leaf beetle is causing local injury to
string beans in the vicinity of Fayetteville, Siloam Springs,
and Van Buaren."

PFS

PEA APHID (Illinoia i Kalt.)

New Jersey D. E. Fink (Vay 12). "Peas unusually free from attack of
this species at the present tie."' (flay 20). 'The pea
aphid ib becoming noticeable. It is possible that severe
injury ray not occur before the crop is ready to be harvested,
since in most fields the pods are already forced."

Delaware J. F. Adars (IMay). "Serious injury by this species is reported from several localities in southern Delaware."

California Victor Duran (Fay 5). "On April 27 in the San Joaquin Valley,
vines wer6 found to be infested almost solely by alate females,
there being comparatively few young. By M[ay 5 the young were
more abundant and many apterous. females had developed. In
sore fields the infestation would average about 10 or 15 late adults to a foot of row, while in one field there
wore fully 300 in this space. The fields are scattered and
srall,the average acreage for each grower being about 15
acres. Much alfalfa is grown in the locality, and the greater
part of this was cut butwPen April 15 and 30. Aphids in all
stages were found on alfalfa, and in view of this fact, the
abundance of alate individuals on the peas, the co-paratively
srall number of young seen on the vines, and the healthy
conditions of the plants supporting large numbers of aphids,













it seems evident that a Lgraticn of this insect from alfalfa
to peas had just taken lace. In this region there is a
total acreage in peas of approximately 1,000 acres."

STRIPED CUCUBER BEETLF (Diabrotica vittata Fab.)

Ohio T. H. Parks (May 20). "Quite troublesome on felons in the
southern and central counties. The gypsurm-&rsenate of lire mixture (one partof arsenate of lime to 20 parts of gypsum by weight) is giving good results where applied at frequent
intervals to repel the beetles."

Indiana J. J. Davis (IMay 15). "The striped cucumber beetle is corron
as usual in the melon section of the southwestern part of
Indiana. They first made their appearance at Vincennes about
the first of nay. From a general survey at Decker near
Vincennes, apparently the striped beetles are not as abundant
near the river where the overflow covered the ground, but
farther back from the river they are in conspicuous numbers.
It seers that the overflow destroyed many of the beetles
hibernating along the river."

H1issouri L. Haseman (1ay 10). "This beetle is worse than usual for this
season of the year and has already been reported as ruining
early melon crors in Boone County."

arkansas Dwight Isley (M'ay 22). "The striped cucumber beetle is causing
severe injury to canteloupes in the vicinity of Van Buren.
Percentage of hills killed in commercial fields ranges from
20 to 100."

Louisiana T. H. Jones (May 11). "Mr. C. E. Smith of the Bureau of
Entomology reported the first finding of beetles in field of
Baton Rouge today."

New Mexico R. Middlebrook (April 7). "This beetle appeared ten days
earlier than usual this year, first being observed on March
15, in the Vesilla Valley."

FLORIDA FLOWER THRIPS (Frankliniella bispinosus pro jectus 7atson)

Florida K. C. Moore (May 10). "elons and canteloupes did not set
more than one-quarter of a crop in many localities throughout
Marion County on account of thrips."

COTTON APHID ( pi ossvpii Glov.)

Ksnaas G. A. Dean (MIay 15). "This insect is just beginning to appear
around Manhattan and undoubtedly will soon appear over te
entire State."

ONION TERIPS (Thrips tabaci Lind,)

Louisiana T. H. Jones (May 4). "Judging from recent reports onion
thrips caused considerable damage in southern Louisiana this year. Badly injured plants were sent in fion Bowie on May 1, ard what is vw iiout doubt this insect was reported to be
playing havocO'" vith the onion drop in Terre Bonne Parish.
District extension agent for southern Louisiana also reports
that severe injury was general this spring over southern
Louisiana."

WHEAT VIREOPR1 (.griotes mancus Say) New York C. R. Crosby (!ay 16). 'Tr"ireworms are reported as attacking
onions and lettuce at Elba."

HORSFRADSH

HORSERADISH FLEA-BEETLE (Phyllotreta armoracieae Koch)

Massachu- H. T. Fernald (May 20). "This insect was observed at Amherst
setts this year. It is the first record that I know of for
Massachusoetts."

SPINACH

GREEN PEACH APHID (ryzus persicae Sulz.)

California R. E. Campbell (May 1). "The entire acreage grown on the Pala
Indian Reservation in San Dioego County was infested but spraying was begun in time and most of the damage was avoided.
Predators were negligible in this outbreak but Empusa aphidis was
destroying from 25 to 50 per cent of the aphids in some
fields."

SUGAR-CANE BFETLE (Euctheola rugiceps Lec.)

Louisiana T. E. Holloway (May 23). "A search in rice, corn, and sugarcane fields at various points in southern Louisiana has been
made for the sugar-can beetle but very few of the beetles
have been found. They are doing some damage near Franklin
but, in genceal, they seem to be scarce."

SUGAR-CANE BORER (Diatraca saccharalis Fab.)

Louisiana T. E, Holloway (May 23). "The sugar cane moth borer has
appeared vpry early this spring after a mild winter. It is
about a month earlier than usual, a second-instar larva having
been fcurA on April 18. This corresponds with conditions
last year when borers showed up in the middle of April, the
winter of 1920-21 not being at all severe."

ANOM ALA (Anomala orientalis Waterh.)

Connecticut W. E. Britton (May 24). "Two or three specimens of this
beetle were firs--t collected on grass and weeds among pines in a nurL'-ery at Ie aven in July, 1920, by Pessrs. Walden and 7apo. The beetle was again taken in 1921 in the sarre
place but only a f:w specimens. I have just been able to
get the specis d1,terrined. It is said to injury sugarcane in fwnil andc i.riy prove to be a serious pest. The
beetles were identified at the British Huseum."

V'isconsin S. B. Fracker. "A nymph possibly of the 1922 brood of the
periodical cicada was collected at Leigh, about 'a- 1.
This is over 100 miles from the known distribution of this
brood. Specimen sent to Bureau of Entorolozy for verification." (Wr. 1'. L. VcAtee, U. S. Biological Survey, determined
the nyrph as Cicada sentendecir L. but probably of a later
brood.)

Ohio H. A. Gossard (!'ay 26). "A considerable tract of park forest
with trees of all sizes and much undergrowth was dusted by
aeroplane this -reek, the work bein done cooperatively by
the Experiment Station, the city park department of Cleveland
and icCook Aviation Field. The woods -ere infested with
canker-e!7r-;. Under very difficult conditions the "york was
successfully done and the distribution of the poison was
excellent on woods and undergrowth. Notwithstanding heavy
rains, the killing effect on the caterpillars has been
excellent. This test has satisfied all entomologists who
saw the work and the results that dusting by aeroplane is a
very practical method of treating forest areas and that only the details of practice yet remain to be learned."

examined, was Reticulitermes virrinicus Banks,"

(May 23). "A serious infestation of termites in a store
building in Indianapolis was investigated. The floor was
laid directly on cinders over the ground and the baseboards
around the edge of the rooms were also in direct contact with

Reticulitermes flavires Kol."

Missouri A. C. Burrill (May4). "A serious infestation by white ants
has been investigated in DeKalb County. Practically 10 per
cent of all the woodwork on the farm was destroyed, the insects
even attacking grain in wooden bins, Cement bases have been placed under some of the buildings but the ants make tunnels

Louisiana T. H. Jones (April 29). "The horn fly is nowquite abundant."

STABLE FLY (Stocoxys calcitrans L.)

Texas F. C. Bishopp (May 22) "Stable flies have been quite annoying
to live stock in the vicinity of Dallas during the past two

some animals being infested with from 50 to 100 flies during
favorable fly periods."

SCREW WORM (Chrysomyva macellaria Fab.)

Texas F. C. Bishopp (May 22). "Although adults of this pest continued
abundant in southwestern Texas screw-worm cases were not
especially numerous during early May but have increased considerably since the middle of the month. At El Paso and Alpine
the adults were comparatively. scarce on May 11. Toward the
end of the month the species became very abundant in the vicinity
of Dallas."

annoyance to stock hear Amite River. Tabanus rumilus was the
most numerous of the species observed."

'CATTLE SCAB (Psoroptas cogrunis Furst.) California (Weekly News Letter, California Dept. Agr.). "The introduction
of cattle scab in Mono County, reported in the last number of
the Survey Bulletin, has probably resulted in the establishment of this pest in the State. A few cattle in the Antelope Valley
have been found to be affected with scab. Vats are new being
constructed for the purpose of dipping infested cattle. Careful
survey indicates that the establishment of an effective quarantine
and consistent dipping will prevent further spread of the scab
