Volume 18 June 1, 1938 Number 4











Vol. 18 June 1, 1939 No. 4


From the Northern Rocky Mountain art-a southeast to Illinoin hatch-
ing of grasshoppers has been delayed by recent rains, althouWh mortality
due to rains has been slight. A hatch of 60 percent was reported from
the southern part of the grasshopper-infested territory. Campaigns are
being conducted in the areas infested by Dissosteira longipennis Thos.
in Colorado, New Mexico, and Texas, with migration reported from aban-
doned lands in New Mexico.

The Mormon cricket has largely hatched and control operations have
been started in Utah and Nevada..

The cool, rainy weather cast of the Rocky Mountains his been con-
ducive to cutworm injury, and reports of unusual abundr.-iLco have been
received from almost every State.

The armyworm infestationri reported last month has extended to in-
clude Oklahoma and Missouri, southern Illinois and Il.Uia:,a, western and
central Kentucky, and western Tennessee. I1 these areas the caterpillars
arQ damaging small grains, corn, and pasture. :.oths were observed
throughout Ohio, Indiana, and Illinois, and also in Utah, New York, and
l.inine. An additional small area wh._re damage is occurring extends from
northeastern North Carolina, along the Atlantic coast through Virginia
and Maryland.

The cool weather acconipar.led by frequent rain hc.s been unfavorable
to chinch bug development and damae this year is as yet u.determinable.
The insect was reported in scattered locations in much of the chinch
bug belt, where damage is anticipated in occasional areas.

The hessian fly has been favored by the spring weather and popu-
lations have built up considerably, resulting in som: d.'.ni:eo to wheat.

The corn ear worm was reported injuring sweet corn and tomato in
South Carolina, Mississippi, Louisiana, and California. Moths wore ob-
served at Now Brunswick, N. J., on.May 13.

The codling moth begp.n emergirl earlier than usual, being observed
the last week in April along the Ohio River and in northeastern Kansas
and northwestern Missouri, also in the Middle Atlantic States. The
peak of moth emergence occurred the first week in May. Cool, wet
weather delayed development, but some hatching and a few entrances wore
observed by the middle of the month. The first adults were observed on
May 17 and 18 in Now York. In the Yakima Valley, Wash., the emergence
started about the same timo as in the eastern part of the country.

The rosy apple aphid is more abundant thin usual in the Middle At-
lantic States and in the Ohio Valley. The other species of apple aphids
are occurring in only moderate abundance. The black peach aphid is more
abundant than usual in the Middle Atlantic States.

Flea beetles are very abundant on an.d injurious to truck crops over
the entire country.

The Colorado potato beetle is appearing earlier than usual and is
causing considerable injury over the Middle Atlantic Stn.teg and in the
Mississippi and Ohio Valleys. The insect was also reported from south-
onstorn Idaho, where it has never been observed before.

The Mexican bean beetle is coming out of hibernation earlier than
usual. Egg rmasses were found on LEay 5 in southern Indiana.

The pea aphid is very abundant along the Atlantic coast from Vir-
ginia to New York; however, it is not so injurious as it was last year.
Considerable injury to peas is occurring in southern Wisconsin and
Illinois and to alfalfa in the Western States.

Boll weevils were moderately abundant in the field over most of the
Cotton Bolt.

The cotton leaf worm appeared in Toexas earlier than usual.

Thrips of many species are unusually abundant on truck crops, cotton,
and flowers over most of the country.

Illinois. W. P. Flint (May 23): There is less than 25-percent hatch
in the sand areas and not more than 5 percent in other areas in cen-
tral Illinois. The numbers of hoppers are not great enough to cause
serious darta,:.

Michigan. R. Hutson (May 26): Camnula pellucida (Scudd.) is hatching
all over the northern end of the Lower Peninsula and beginning to
hatch in the Upper Peninsula. Hatching began in the week of April
l1 in favored locations throughout the Lower Peninsula. Hatching
of Melanoplus mexicanus (Sauss.) and M_. femur-rubrum (Deg.) did
not begin until a week to 10 days after the time when Camnula was
first observed. Cold weather during the week begirir-inr I.Iy 16
practically eliminated nymphs of all species hatched prior to that
time. A sufficient reserve of eggs remains to form the basis for
a heavy infestation.

Minnesota. A. G. Ruggles (May 19): Less than 1 percent of red-ler-7ed
grasshopper and the two-striped (Melanoplus bivittatus Say) have

Iowa. C. J. Drake (May 27): Heavy rains and cool weather have greatly
delayed grasshopper hatching. In central Iowa incubation is just
beginning and not over 10 percent of the e have hatched in the
southernmost counties. Late fall plowing of infested clover fields
did not materially affect grasshopper ege';. Populations of over
200 young hoppers per square yard have been found in newly seeded
alfalfa fields in a r.urber of counties.

H. E. Jaques (May 25): Grasshoppers are now hatching in large
numbers throughout much of southern Iowa.

Missouri. L. Haseman (May 23): Conditions have been decidedly unfavor-
able for grasshoppers during the second half of May. It was in-
dicated that 50 percent or more of the lesser migratory eggs (M.
mexicanus) hatched during the first few days in May, but hatching
has slowed down in the last 2 weeks uand conditions have not favored
the young nymphs. Z,-s of the differential grasshopper (Melanoplus
differontialis Thos.) are still largely unhatched. In some places
the lesser migratory nymphs are half grown or larger.

North Dakota. J. A. Munro (May): Hatching has been general throughout
the State, with more than 75 percent of the eggs hatched in south-
western counties. Crop injury to alfalfa, sweetclovor, and cereals
reported in southern counties. A week of cool, rainy weather has
retarded hatching and feodi;-.(: activities.

South Dakota. H. C. Severin (May 20): E-s of M. mexicanus were the
first to hatch. It is estimated that as high as one-third of the

- 150 -

eg-'s are hatched in some localities. The first damage was reported
on May 10 in M;arshall County by first- and second-instar nymrhs.
Ths first damage caused by M. bivittatus was reported on May 12
from the northern and western sections of the State.

Nebraska. 1. H. Swenk (May. 20): Grasshopper eggs began hatching freely
early in "a":, and probably from 25 to 30 percent have hatched.
Heavy populations are developing in many localities.

Kansas. H. B. Hungerford (May 23): Yotung grasshoppers are beginning
to be generallytroubcloomo in flower gardens.

J. R. Horton (May 3): The first grasshoppers hatched around
Wichita were seen during the last week of March. Only individuals
and small groups have been seen as yet and there is no damage to
spring wheat, which has been above ground only a few days.

Arkansas, Oklahoma, and Texas. W. E. Dove (May 14): All species are at
least 60 percent hatched, being confined for the most part to field
mari.ns and original hatching, grounds. Different species wore found
as follows: Y. rmexicanus in the fourth and fifth instars and as
adults; M. difforentialis in the first, second, and third instars;
M. bivittatus in the third, fourth, and fifth instars; and Dis-
sosteira lon7ipennis Thos. in the first instar.

Oklahoma. F. A. Fenton (.ay 20): The grasshopper infestation promises
to be i.ore serious in many localities than the infestation last year.
In places in Kay County M. mexicanus occurs at the rate of 100 per
square foot. 1. confusus Scudd. is in the adult stage and is very
abundant in some places.
C. F. Stils (LMay 25) :; Approim.toly 80 percent of grasshopper
eggs hv..V hatched nd reports of crop injury are being received
from southwestern Oklahoma. The principal species are K. mexicanus
and M. differentialis. The situation is becomir..- alarming in five
counties, whore the rainfall was light until recently.

Texas. F. L. Thonias (May 25): Grasshoppers constitute a serious threat
Sto all crops in northwestern Texas.

Montana. H. 3. Mills (.L.v 19): In some areas approximately 40 percent
of the hop:-;rs had hatched by "aLj 7. Hatchirn-ir has booeen considerably

Colorado. S. C. .cCampbell (May 23): Hatching has been delayed over our
native hopper area, where less than 1 percent hatch has occurred.
Fro: 5- to 25-percent hatch has occurred on the warmer soils in the
r.i ratory-grasshopper area.

Arizona. C. D. Lcbert (May 26): Several heavy infestations of M. moxi-
canus in &alfalfa were observed during the middle of ,May in the Salt
River Valley.

- 151 -

Idaho. J. R. Douglass (May 5): Grasshoppers were beginning to hatch
in the Snake River Plains at the end of April.

Utah. G. F. Knowlton (May 12): Hatching has been noticed in fields
in northern Utah. (May 14): Hippiscus corallipes (Hald.) is now
adult in the foothills of Tooele, Juab, and parts of Millard
Counties,in central Utah. (May 23): Grasshoppers are beginning
to damage alfalfa and pasture lands in southwestern and south-cen-
tral Utah.

MOR1MON CRICKET (Anabrus simplex Hald.)

North Dakota. J. A. Munro (May 24): 3-mmous County, in south-central
North Dakota, is heavily infested with recently hatched Mormon
crickets. These pests were also found at the rate of 300 per
square yard along field margins near Roedor, in Adams County, in
the southwestern part of the State.

South Dakota. H. C. Sevorin (May 20): Mormon cricket eggs began hatch-
ing on April 19 in Lyman County, in south-central South Dakota,
and on L.ay 20 in Butte County, in the west-central part of the
Statu. No damnreo reported as yet.

Montana. H. B. Mills (May 19): Mormon crickets have largely hatched in
the lower arci.s and indications arc that they will be as abunda-nt,
if not more so, than they were last year.

Utah. C. J. Sorcnson (May 19): M orrmon crickets have occurred in numbers
menacing to agricultural crops in Juab, Millrrd, anrid Toocle Counties
in west-central Utah. Crop damage is being prevented by control

Nevada. G. G. Schweis (0a" 5): Mormon crickets have hatched on the
lower and intermediate elevations in eastern Nevada and control
work was started on a large scale on May 5.
CUTWORI iS (Noctuidao)

Maine. H. B. Peirson (:'lay 10): The variegatd-d cutworm (Lycophotia
margaritosa saucia Hbn.) was doing severe damage to greenhouse
plants in Bar Harbor.

New Jersey. J. B. Schmitt (May 24): Cutworms are becoming serious in
Burlington County, some cornfields showing 10-percent destruction.

Delaware. L. A. Stearns (May 19): The death of 70 percent of a new
planting of peaches near Bridgeville is attributed to girdling
of the young trees by cutworms. The field had been in watermelons
in 1937 and cutworms had been abundant then.

Maryland. E. N. Cory (May 24): Cutworms have been damaging tobacco
in Calvert County.

- 152 -

Virginia. H. G. Walker and L. D. Anderson (May 25): Cutworms have been
unusually nbu-idant near Norfolk since the latter part of April.
They have cut off a great many tomato, bean, and corn plants, and
have been very numerous in alfalfa fields.

South Carolina. J. G. Watts (May): An unidentified cutworm has been
found in great abundance in a field of soybeans near Blackville,
in the southwestern part of the State. The beans followed rye
and vetch, planted as a winter cover crop. A maximum of 21 cutworms
was found around a single hill. The same species has been
found in much smaller numbers d-v-iagin- cotton, corn, and tomatoes.

Georgia. 0. I. Snapp (May l1): Near Fort Valley, in central Georgia,
cutworms have destroyed 50 acres of young corn, planted after
Austrian winter peas had been plowed in, and also damaged cotton
and peppers under the same conditions. Truck crops in the same
locality are damaged.

G. F. Moznette (May 19): Cutworms are destroying corn, peanuts,
and cotton in scattered fields in the vicinity of Leary. Infes-
tations are most severe where winter cover crops of vetch and
Austrian peas have been plowed under, as many as 12 larvae being
taken from a single peanut plant.

T. L. Bissell (May 23): Cutworms, possibly the variegated
cutworm, have seriously injured one field of cotton at the experi-
ment station and are less injurious in two other fields. These
fields were planted after vetch and the s?.me cutworm is found
around vetch plants not yet plowed.

Indiana. J. J. Davis'(May 23): Cutworms have been rather general
throughout the State, attacking a wide range of crops, principally
garden crops.

Ohio. T. H. Parks (May 19): The first serious outbreak of the bronzed
cutworm (Nerhelodes emmedonia Cram.) since 1925 was brought to our
attention on ,y 13, when it was found to be destroying bluegrass
in permanent pastures in eastern Franklin and western Licking
Counties, in central Ohio. About 35 acres of bluegrass had been
eaten close to the roundd in one largo pasture field by May 17.
The line of demarcation between the infested and uninfested parts
of the field very distinct. At this point the larvae were
massed beneath the grass and were progressing slowly into the new
feeding grounds, destroying the grass as they went. Most of the
larvae were about full-grown and would soon become quiescent. By
May 15 many of the worms had been killed by a bacterial disease
and by May 19 the outbreak was subsiding.

Illinois. W. P. Flint (Eay 23): Cutworms of various species particular-
ly the black (Agrotis ypsilon Rott.) and the clay-backed (Feltia
glaciari. Patch i.:;re been causing generally serious losses to
early planted corn. The injury has been complicated by the fact
that the variegated cutworm(L. margaritosa)and the true armyworm

- 153 -

(Cirphis unipuncta Haw.) are present in cqual numbers and the rank
growth 0 clover in many fields has prevented success with control

Michigan. R. Hutson (May 26): Cutworms .have been reported actbivo in the
following localities: Parastichtis bicolorago Guon. in the vicini-
ties of Parma and South H-vcn; Nephelodes emmedonia Cram., South
Haven; Paragrotis scandens Riley, Albion, Parma, South Haven, Law-
ton, Paw Paw, Saint Joseph, Berrien Springs, Grand Rapids, and
Fennville; Agrotis c-nigrum (L.), Parma; Agrotis unicolor (Walk.),
Muskegon Heights and Manistee; and Feltia ducens (Walk.) at Parma,
Albion, Coldwater, Niles, Berrien Springs, Paw Paw, Saugatuck, Fenn-
ville, Allegan, and. Grand Rapids.

Alabama. J. M. Robinson (May 19): The variegated cutworm was causing
damage on May 11 to young cotton after the cutting of alfalfa on
the northern border of the State. New hay being shipped into
Birmir.ham from southern Missouri was found infested with the
insect. (Iay 26): Cutworms, destructive to cotton following the
turning of winter legumes, have become active in several counties
in east-central Alabama. The larvao of this insect have destroyed
several thousand acres of cotton.

Tennessee. G. M. Bentley (May 24): Serious losses arc reported from
many parts of the State from diffcre-.t species of cutworms, as
well as from the ariyworn. The variegated cutworm has beer. caus-
ing the most damage. The first recorded appearance of cutworms
was on May 5- The outbreak has been the most pronounced in western

Mississippi. C. Lyle (May 24): On May 18 cutworms wore reported by
G. L. Bond, of Moss Point, asunusually abundant in his district.
Crops of various kinds, as well as ornamental plants, have been
severely damaged. M. L. Grimes, of Meridian, and 7. D. Poets,
of Brookhaver, reported considerable injury in their districts.
Specimens of Prodenia ornithogalli Guen., accompanied by reports of
light-to-modiu-i d..amage to young cotton, were received in May from
Adams, Holmes, Frankllir., Lauderaale, and Marion Counties. (May 9):
The variegated cutworm is causing sone damage in the Delta area on
cotton planted following winter leo-)mes, but the injury is small
where planti-.. was delayed until 2 or 3 weeks after turning under
the winter cover crop.

Louisiana. C. 0. Eddy (.ay 23): Cutworms have been abundant throu.h-
out the Stte.o.

Kansas. H. R. Bryson (May 28): The pale western cutworm (Porosagrotis
orthogoniai Morr.) was reported to be abundant at Liberal and Gen
on Mcay 12.

- 154 -

Iowa. C. J. Drake (May 27): Cutworms of various species are common
in Iowa and are doing a considerable amount of damage throughout
the State, particularly in gardens and truck fields. A few infesta-
tions reported in corn.

Missouri. L. Haseman (May 23): A rather severe and general cutworm in-
fostation has been associated with the armyworrn outbreak. The
easyay cutworm is predominant in some areas, though in most collec-
tions the variegated cutworm is more abundant. Garden crops, as
well as field crops, have been severely damaged.

North Dakota. J. A. Munro (May): Reports from infested areas indicate
that most of the larvae of the army cutworm (Chorizagrotis auxiliaris
Grote) have completed development and are in the pupal stage. A
few moths have been taken recently at lights. The pale western cut-
worm is becoming active ini the western part of the State, but no
serious damage has been reported. A field in Golden Valley, examined
on lay 7, showed more than 25 larvae per square foot, most of them
being in early instars.

South Dakota. H. C. Severin (.1ay 20): Cutworm dsmage is being prolonged
and intensified by the cold, wet weather prevailing. The army cut-
worn is responsible for a considerable amount of the damage done.

Kansas. J. R. Horton (May 3): First adults of the season of the army
cutworra were seen on April 29 in the vicinity of Wichita. At
present they are a little more in evidence, occurring in houses as
well as in the field, although only scattered individuals have been
seen. (May 21): Moths cf the army cutworm are probably at their
maximum enerence. Their numbers are larger than at any time in
several years.

H. B. Hungerford (May 23): Cutworm complaints have .been num-
erous .

Nebraska. M. H. Swenk (May 20): The western army cutworm was reported
attacking winter wheat and alfalfa in Keith County on April 26,
and a similar complaint came from Dawson County on the same date.
Moths of this species have been abundant all over the State during
lMay. The dingy cutworm (Feltia subgothica Haw.) and dusky cutworm
(F. vonerabilis Walk.) have been reported as injurious in eastern
Nebraska gardens in Li,'.y.

Colorado. S. C. McCampbell (MIay 23): Array cutworms have been especially
bad during the last 3 weeks in gardens in northeastern Colorado, but
little injury to field crops has boon reported. A few moths arc

Utah. G. F. Knowlton (May 3): Reports of cutworm abundance and injury,
especially to alfalfa, are received almost daily from different
localities in :"l1]ard County. (lMiay 4): Young cabbage plants in
coldframes are reported as damaged by cutworms at M1organ. (May 10):
Moths of the ,,reasy cutworm are now coming to trap lights at Cedar

- 155 -

City, in Iron County. (May 17): Reports of cutworm injury: to young
sugar beets h-LVc been received from Sevier County. (May 20): A
farmer at Green River reports losing half his sugar-beet stand from
cutworm damage this spring. (May 23): Cutworm injury hold back
alfalfa growth for several weeks on many farms on Milford Flots.
Daiagc to fal wheat was serious on a number of far.ns. :!-st of the
larvac have pupated.

Nevada. G. G. Schweis (May 17): Cutworms were observed attacking
various ornamental plants on May 17. They were also observed damag-
ing fields of alfalfa at Fallon and Lovelock early in May.

Washington. K. E. Gibson (May 20): Cutworms were damaging a 4-acre field
of asparagus near Walla Walla to such an extent that cutting had
been practically stopped. Stalks were being cut off at the soil
surface or just below, and other stalks were cut off from 2 to 3
inches above the soil. Other a.n- wcs done through chewing of the
stalks until they were deformed.

BEET WE3WORI.' (Loxostege sticticalis L.)

Colorado. G. M. List (:.:2y 2S): Moths are fairly numerous on the lawns
and about the lights at Fort Collins.

Utah. G. F. Knowlton (May 23): Moths observed in alfalfa fields in
southwestern Utah.

H. E. Dorst (MIay 29): No moths of the sugar beet webvworm have
been observed in sugar beet fields in central Utah despite the enor-
mously high population in 1937.

WR-7OMI*S (Elateridao)

Connecticut. A. W. i1orrill, Jr. (.'ry 17): Larvaec of Limonius agonus
Say have been found attacking potatoes and radishes for over a
month, in fairly lar.e rumbcrs in some fields in Hartford County.
Adults have recently been found on radishes just below the ground
line and on potatoes plant._d as test baits in fields being prepared
for tobacco.

Maryland. E. N. Cory (M.y 4): Wircwrr;s have been reported dam'rging
tomatoes in Somerset County.

d:ma-e to corn in southeastern Iowa.

- 156 -

Kansas. H. R. Bryson (May 2S): A small wireworm,Aeolus elegans F,,
was reported causing injury to wheat at Ashland on April 29.

Idaho. F. H. Shirck (May 17): Several fields of onions in the local-
ity of Parma have been damaged by L. californicus Mann. The in-
jury began about May 10 and amounts to a thinning of stands.

Nevada. G. G. Schweis ('ay 10): Wireworms were reported as damaging
gardens in Reno on May 10.

Washington. E. W. Jones (May 20): Adults of the sugar beet wireworm
reached their peak of emergence at Walla Walla on May 10. The
first emer/oence at Walla Walla of Athous pallidipennis Mann.
occurred on May 9. This species was found to have transformed from
overwinteri2-g larvae in April,

Oregon. I4. C. Lane and H. P. Lanchester (Mlay 20): Extensive dMnage to
fall, sprint, and resown spring who-At was noted near Athena, in
northeastern Oregon. In one field of spring wheat 84 acres were
replanted, owing to complete loss of the stand through wireworm
feeding. The infestation was primarily the sugar beet wireworm.

California. M. W. Stone (May 18): Lima beans planted early in May
were damaged to the extent that replanting was necessary in several
fields in Orange County. Siftings made in bean rows in a field near
Sncltzer on 'May 17 showid an average population of 1.2 and as
many as 2.4 wireworms per foot. In the wireworm plots near Downey,
in Los Angeles County, an average of 3.9 larvae per foot were recov-
ered in rows of field corn, and an average of 8 larvae per foot
in sued-potato rows.

WHITE GRUBS (Phyllophyga spp.)

Vermont. H. L. Bailey (May 28): The first adult was noted at Mont-
pelier on May 22, but beetles have been very scarce.

Connecticut. E. P. Felt (May 24): June beetles (P. tristis F.) were
reported defoliating oaks at Middlebury.

Mississippi. C. Lyle (:"ay 24): On Uay 10 a grower at M1eridian, in
Lauderdale County, reported considerable damse to pecan trees by
P. hirticula OKnoch), P. micans (Knoch), P. crenulata Froel., and
P. praetermiissa Horn. The last was also reported as doing severe
damage to oak trees at Houston, in Chickasaw County.

Wisconsin. T. R. Chamborlin Knd assistants. (May 23): The first
flight of June beetles near Madison occurred on April 25. A
rather large flight was observed nc ar Dane, in Dane County, on
April 26. Flights thereafter were materially reduced until May 1$,
because of cold, rainy weather, A small flight was observed near
Leeds in Col'irbia County, on May 13, with the temperature at only

- 157 -

4g0 F., the lowest temperature at which we have seen beetles emerge
in any numbers. All the beetles taken belonged, to the species P.
fusca (Froel.). This species, together with P. tristis, has been
the first to emerge in the spring during the last three seasons,
probably because it flies at lower temperatures than most other
species in this territory. Beginning on May 18, temperatures have
been somewhat higher and the size of the flights has increased.

Minnesota. A. G. Ruggles and assistants. (May): May beetles are
quite abundant in the eastern and southern sections of the State.

Iowa. H. E. Jaques (May 25): May beetles of several species are fly-
ing in extraordinary numbers on warm nights. Elms ,nd some other
forest trees are showing evidences of defoliation.

Kansas. H. R. Bryson (May 28):The wheat white grub (P. lanceolata Say)
was reported on M4y 5 as having destroyed approximately 500,000
acres of wheat in southern and central Kansas.

Oklahoma. R. G. Dahms (May 23): Adults of P. lanceolata are very
abundant in many wheatfields in southwestern Oklahoma. Although
observed feeding on leaves of Sudan grass, they appear to be doing
little damage.

Oregon. M. C. Lane (May 20): :-umerous females of P. anxia Lec. were
flying to lights on May 10 at Ontario.

JAPANESE BEETLE (Popillia japonica Newm.)

Connecticut. J. P. Johnson (May): Grubs of the Japanese beetle have
been feeding on the roots of grass in New Haven, Bridgeport, Stamn-
ford,and 3rc(onwich, causing considerable injury.

Delaware. L. A. Stearns (IL-y 23): Severe dcimpge to untreated l,'. ns in
N1kv Castle County, with counts showing a grub population of from
20 to 30 per square foot.

Maryland. H. P. Boyd (May 19): Worms found under patches of dead grass
in lawns a.t Perryville.

ORIENTAL BEETLE (Aniiomala crientalis Wtrh.)

feeding extensively in New Hrven, Bridgeport, Stanford, and Green-
wich. Lawn injury has been inreinly .videt.
has benin-e ingly evide.:tt

New Jersey. E. G. Brewer (May 27): Invosti.--ttion of a reported severe
injury to a 5-acre lawn on an estate at Oakland, in Bergon County,
disclosed extensive grub fcedi.,- by A. orientalis. Approximately
W acre of sod had been completely destroyed. There was a high grub
population throughout the lawn. All larvae examined were of the
same species.

- 158 -

A SCARABAEID (Ochrosidia villosa Burm.)

Connecticut. J. P. Johnson (May): Grubs of this insect have been found
in increasing numbers in Norwalk end Greenwich. It is evidently
spreading and building up in strength. Some winter killing of the
grub stage was evident upon examination.

ASIATIC G-ARDE: BEETLE (Autoserica castanea Arrow)

Connecticut. J. P. Johnson (May): Grubs of this insect have been feed-
ing extensively in New Haven, Bridgeport, Stamford, and Greenwich.
Lawn injury has been increasingly evident.

ROSE CHAFER (Macrodactylus subspinosus F.)

Delaware. L. A. Stearns (lray 17): First adults of the season observed
on young peaches in Sussex County on May 17.

Tennessee. G. M. Bentby (May 24): The rose chrfer has been found at
Crossville, in Cumnberland County, and at Wartburg, in Morgan
County, on potatoes. It is occurring in large numbers, comparable
to a medium-sized swarm of bees.

WHITE-FER1G= BEETLE (Naupactus leucolomia Boh.)

Alabama. B. M. Gad.dis (May 9): The white-fringed beetle was emerging
the first week of May.

Mississippi. J. B. Gill (Ma:- 24): The first pupae of Naupactus sp.
from insoctary material were obtained on Mlay 6. It is also interest-
ing to note that the first pupae collected in thc-field were taken
on this same date. Up to MWy 24 no adults have been found feeding
on the foliage of plants in the field. However, two well-developed
adults wore dug out of the soil--one on May 17 and one on May 20.
The larval injury to the roots and tubers of plants by Naupactus sp.
is apparently quite similar to that of N. leucoloma.

FALSE CHIIIUCH BUG (Nysius cricae Schill.)

Michigan. R. Hutsonri (May 26): False chinch bug has been observed at
White Cloud, Muskegon, Manistee, and other points in the grass-
hopper infested region of last year.

Utah. C. J. Sorenson (May 19): The false chinch bug is abundant in
meadow lands and alfalfa fields near Whiterocks, in Uintah County.

H. E. Dorst (May 28): A very low population of the false
chinch b' is present on ra:-ic land adjacent to northern Sevier
Valley,as compared to the high population in 1937.

ARIAYWO.i (Cirphis unipuncta Haw.)

Maine. H. B. Poirson (May 10): An unusually large number of moths flying
at Bar Harbor, in southeastern Maine.

New York. N. Y. State Coll. Agr. News Letter (May 31): Moths found in
large numbers nightly during the last 9 days at Ithaca and Oswego,
in western New York, indicate the possibility of an outbreak. The
number caught is reported to be 100 times that of average years,
from 10 to 50 moths being seen at times on 1 baited tree.

Virginia. H. G. Walker and L. D. Anderson (M!ay 25): Armyormns were very
abundant and destructive in a great many alfalfa, small-grain, and
cornfields in eastern Virginia during the latter part of April and
the first part of May. (May 31): Moths of the second generation
observed at lights near Norfolk on May 29 and 30.

Maryland. E. N. Cory (May 17): A serious outbreak reported from Somer-
set County on the E2-,torn Shore. The worms are attacking oats,
barley, pasture land, and the buds of young strawberry plants.

North Carolina. C. S. Brimley (April 29): This pest is reported damaging
wheat in Halifax County, in the northeastern part of the State.

Ohio. T. H. Parks (May 24): Moths are being captured commonly at
Columbus, in south-central Ohio, in a light trap and in bait pans
used to trap codling moths.

Indiana. J. J. Davis (May 23): Outbreaks were anticipated because of
the appearance of moths in abundance inmany parts of the State some
5 or 6 w:,-:s ago. We received a report on May 11 of a general out-
break in Martin County, in the south end of the State. No further
reports have been received.

L. P. Steiner (iiy 9): An outbreak is occurring adjacent to
one local orchard in Vincennes, in southwestern Indianr.

Illinois. W. P. Flint (May 23): As expected, armyworns have been hatch-
ing in the southern and south-central parts of the State during
the last 2 weeks and are now hatching in nxubers in the central
part.. The injury has been complicated by the fact that the v-.rie-
gated cutworm (Lycophotia rnargaritosa saucia Hbn.) and the true
armyworm are present in about equal numbers and the rank growth of
clover in many fields has prevented successful control of the
former. Very few parasites have been present.

Kentucky. W. A. Price (May 28): Spring armyworms appeared in scattered
sections over the central and western parts of the State.

Tennessee. G. M. Bentley (May 24): There have been serious losses in
many parts of the State from the armyworm.

Missouri. L. Haseman (May 23): During the first half of the month a
severe outbreak of armyworms was reported from the Arkansas line
almost to the Missouri River, especially throughout most of the
southeastern counties. On some farms the infestation was more
severe than a year ago, with fields of wheat, pastures, and meadows
practically stripped. Heavy baiting in that area has been carried
on. Since May 15 in central and northern Missouri the worms have
reached the stage of development whore they have booeen attracting
considerable attention, although, from the Missouri River to Iowa,
the infestation is much less severe than a year ago except on
scattered farms. At Columbia most of the arnyv.orrms are approxi-
mately half grown, with occasionally a very small caterpillar and
an almost full-grown specimen. Devclopnent is much more uneven
than a year ago and in northern Missouri it now appears that the
injury will be far less than in 1937.

Oklahoma. F. A. Fonton (May 20): The infestation in Oklahoma parallels
last year's outbreak in intensity. Certain areas report much greater
damage than last year, while the reverse is true in others. Actual
damage to wheat this year is believed to be greater than last year
because the armyworms wore forced to feed on the heads at an earlier
date because rust has destroyed most of the leaves.

Utah. G. F. Knowlton (May 25): Moths were coming in numbers to the
trap light at Cedar City on May 10.

CHITCH BUG (Blissus leucopterus Say)

Indiana. C. Benton (:.ay 23): Spring flight from hibernation to small
grain near La Fayette was practically completed by May 1, most of
it taking place during the last 10 days in April. The cold wet
weather last month has been unfavorable for chinch bug development,
although considerable mating and other activity has been observed
on warm days. General infestation of winter wheat and rye in this
locality has buen light; but, as the bugs are now deserting the
ranker wheat and concentrating in the thinner stands, occasional
concentrations can be found that will produce moderately severe
infestations if weather conditions are favorable. Some eggs and a
few-first-instar.nymphs, the first observed this season, were seen in
spring barley near La Fayettc on May 21.

Illinois. W. P. Flint (May 23): Chinch bugs were present in small
grain, particularly barley, thin wheat, and oats. The infestation,
while scattered, is very severe in somo of the southern, south-
central, and central areas. For the last 10 days frequent rains
have considerably rodicod the numbers of adult bugs, and .will cer-
tainly lesson the damage.

Iowa. C. J. Drake (May 27): Chinch bugs occur in threatening numbers
in the two southern tiers of counties in Iowa and arc found
occasionally in the third tier. The infestation is spotted ,.nd is,
perhaps, comparable to the infestation in the spring of 1934. Un-
less weather holds the insects in check, many fields of small ,rain
will be b.dly injured.

Missouri. L. Haseman (May 23): Only in scattered areas of the State
are the farr.:ers reporting any concern about chinch bugs. Excessive
rainfall, which has covered most of the State this month, has tend-
ed to check chinch bug spread and development.

Kansas. H. R. Bryson (May 29): Chinch bugs are quite scarce in most
sections, but are abundant in barley fields in eastern Kansas. This
may or may not be an indication of actual population. Young bugs
appeared in southern Kansas before the middle of May.

Oklahoma. F. A. Fenton (May 20): Chinch bugs reported at following
localities in the central part of the State: Britton, in Okla-
homa County; Stroud, in Lincoln County; and Bristow, in Creeook County.

R. G. Sahms (May 23): Infestation seems to be very spotted
in southwestern Olkahoia. Bugs are especially abundant in spring
barley. The first nymphs were found on May 5. E,-js have hatched
very rapidly during the last week, and there are many nymphs in the
first and second instars, and a few in the third. The overwintered
adults are still laying eCgs.

MlADOW PLA-TT BUG (Miris dolobratus L.)

Indiana. J. J. Davis (May 23): .luaLow plant bug reported attacking
wheat more or less generally in Rush County, in central Indiana,
on May 13; and, from general reports, it is sp]arontly rather pre-
valent in other areas. Reported from Huntington County on May 23.

GR!IE" BUG (Toxoptera graninum Rond.)

Oklahoma. F. A. Fcnton (May 20): Green bug in wheat reported from
Willow, in southwestern O':lahona, .nd in oats from Coy-le, in the
south-central part.

APHIDS (Aphiidac)

Kansas. J. R. Horton (May 3): Aphids (spring grain aphid?) have been
slowly increasing in wheat in the vicinity of Wichita for about a
month. They are now numerous enough to be noticed on casual in-
spection of wheat. Perhaps 100 percent of plants in lowland
situations h-irbor one or more snall groups of individuals. Wir.ged
forms are still very scarce.

A LEAF BUG (Labops hirtus Knight)

Montana. H. B. Mills (May 26): This little leaf bug is rather abundant
in Big Horn and Carbon Counties, in south-central Montana. On one
ranch southeast of Hardin, it is doing serious damage to a small
area of winter wheat and. a large area of range land.

HESSIAN FLY (Phytophaga destructor Say)

Indiana. W. B. Cartwright and C. Benton (May 23): Most of the spring
brood of hessian fly emor'eod during the latter half of April in the
vicinity of La Fayette. Most of the egg laying occurred between
April 20 and May 1. A few eggs were still found on May 7 during
the regular weekly examination. Several full-grown larvae
were found on April 29 and first puparia on May 7. By May 14
about 20 percent of the larvae had pupated and 87 percent on May 20.
With unusual early development of the flies it appears that some
supplementary brood may result if weather conditions continue
favorable. On May 20 examination of 100 puparia from near Delphi
showed 3 percent pupated. Examination of a number of winter wheat-
fields in Benton and Tippocanoe Counties, in west-central Indiana,
shows considerable fly infestation by the spring brood, even in
those fields seeded last fall after the safe date. The cool wet
spring has been favorable for a rather general build-up of fly
infestation. In a number of fields the infestation is severe
enough to reduce the yield materially.

Michigan. R. Hutson (May 26): A field of wheat containing approximately
20-percent infestation of hessian fly was found at Hillsdale, in
southern Michigan. Other fields in the vicinity were less heavily


Pennsylvania. E. J. Udine (May 21): On this date the adults were
numerous in wheatfields at Carlisle, in the south-central part of
the State.'

STRAW WORM (Harmolita grandis Riley)

Indiana. C. Benton (Hay 23): About 5-percent infestation observed in
several winter whoatfields in Benton and Tippecanoe Counties.
Infested plants examined from May 15 to 20 showed pupae in galls,
both honey-yellow and black-colored. A few adults wore active
in the fields.

JCINT WORM (Harmolita tritici Fitch)

Indiana. C. Benton (May 20): One field of winter wheat near La Fayette
showed a slight infestation (estimated about 1 percent). The in-
fested stalks wore starting to head, most of then were beaten to
the ground, and showed the characteristically swollen stems.

- 163 -

CLOVER MITE (Bryobia praetiosa Koch)

Oklahoma. R. G. Dahms (May 23): The brown wheat mite (probably B.
pratensis) did serious damage to wheat in southwestern Oklahoma
during the last week of April and the first 10 days of May.


CORN EA.RWORM (Heliothis obsoleta F.)

New Jersey. J. B. Schmitt (May 24): The first moths were found in the
vicinity of New Brunswick, in northeastern New Jersey, on'May 13.

South Carolina. J. G. Watts (May 5-25): Corn earworms were observed
at Blackville, in the southwestern part of the State, feeding on
corn prior to tasseling and on the ears in the milk stage.

Georgia. T. L. Bissell (May 31): Five moths caught in light traps on
May 30. This is a considerable increase, indicating emergence of
first-generation moths. Worms are already damaging tomatoes here
at Experiment, in central Georgia, and at Clarkston in Do Kalb
County, northwestern Georgia. They are focding in small fruits
and on leaves.

Mississippi. G. L. Bond (May 24): Severe damage to both corn and
tomatoes was recently observed at Moss Point, in southern Mississippi.

Louisiana. C. 0. Eddy (Hay): Tomato fruitworms are active on corn and
tomatoes in the State.

Texas. R. W. Moreland (May 28): Injury to buds of corn has been light
in Braz.os and Burleson Counties. Corn has begun to silk and on
100 plants examined 58 eggs were found on 4 silks. The first eggs
were found on cotton on May 23 at College Station.

California. J. Wilcox (May 2): About 20 percent of the tassels in this
early sweet corn field at Olive, in southern California, were
damaged. Egs and small larvae were numerous and a few mature lar-
vae were found. On May 10 examination was made in the same field
and 50 percent of the ears were found infested with from one to
four larvae each. Most of the larvae were in the first, second,
and third instars and a few larger worns were found.

EUROPEAN CORN B0RE (Pyrausta nubilalis Hbn.)

Massachusetts. A. I. Bourne (May 24): We have found that pupation of
the European corn borer began the first week of May in H&rF --en
County, in the lower Connecticut Valley, and moths were emerging
by May 15 or 16. In the upper Connecticut Valley counties and in
Worcester County, in the central part of the State, development
was about 10 to 14 days later, but our observations have shown a
great variation in the development according to the location of the

- 164-

larvae. In corn that remained in the stacks, or was stored in sheds
and has not yet boon disposed of, we found that very little pupation
has taken place, whereas in unplowed fields or where corn refuse has
booeen allowed to remain on the top of the soil practically all the
larvae have pupated. It is expected that this will interfere con-
siderably with the program of insecticide treatment for corn borer
in early sweet corn, which many growers are planning to undertake
this season, as it is certain that moth emergence and appearance
of the larvae will be extended over a much longer period than usual,
owing to thisunevenness of pupation.

Connecticut. M. P. Zappe (May 21): Many overwintering larvae are now
in the pupal stage. A few adults have emerged from cornstalks and
stubble on light sandy soil.

New York. L. A. Carruth ay 19): Examinations of corn stubble in
Nassau County, on Long Island, during the first half of May indi-
cate an avcra. e survival of approximately 25 borers per 100 stubbles,
although in some fields the survival was considerably higher. At
the present time approximately 80 percent of the larvae that sur-
vived the winter in corn stubble have transfornod into pupae. Very
little moth emergence has been observed. Approximately 40 percent
of the larvae which survived the winter in cornstalks in barnyards
in Nassau County have transformed to pupae.

Now Jersey. C. A. Clark (May 20): Spring pupation of the borer advan-
ced very rapidly during the latter part of April and early in May.
Moths started to emerge early in May and counts indicated from 16-
to 42-percent nemergence in MorjKuth and Burlington Counties by
May 19. E2,; deposition has beeoon delayed by low temperatures at night.

J. B. Schnitt (May 24): E.icr.;ence of the European corn borer
is about 60 percent in southern 1-Tew Jersey and about 15 percent in
the northern part of the State.

PEA APHID (Illinoia pisi Kltb.)

Now Jersey. J. B. Schnitt (May 24): Outbreaks in Now Jersey are serious
in dairying sections, and wherever alfalfa is grown, and are
accompanied by pea mosaic. In areas away from alfalfa the aphid
is not a serious problem.

Illinois. W. P. Flint (l.:ay 23): Pea aphids have been building up in
large numbers in red clover, sweotclovcr, and alfalfa fields. The
infestation in peas has occurred and reproduction has beon king
place for nore than a week.

Colorado. S. C. McCa:-pbell (May 23): This aphid has boon especially
abundant in the Canon City district of Frr'onont County, Juat southeast

- 165 -

of the Pikes Peak area. We have also had a few reports from the
western slope of Colorado, in Delta County. Ladybird beetles and
syrphid fly larvae are abundant and are expected to control this
outbreak soon.

Idaho. R. W. Haegele (May 19): Heavy infestations of pea aphid are
cor.Uion in alfalfa fields throughout southwestern Idaho, where ser-
ious damage is occurring in nar.y fields.

Utah. G. F. Knowlton (:May 13): Pea aphids are abundyrt on alfalfa
arid are becoming established on ,eas in the Salt Lake City area.
They are s., ewhr;t loss abundan.t in northern Utah. In Beaver County,
in soutihwostcrn Utah, 40 acres of alfalfa are reported ,'s destroyed
and 100 acres morc a-s severely d-.:-god. (lay 27): Pea aphids have
reduced the first crop of alfalfa by approximately 50 percent in
Davis County (according to the County Agent's estimate). Damage in
Salt Lake and Utah Counties, especially on the bench la-nds, has
been nearly as severe. Damage is serious in several alfalfa fields
at S.lina, in central Utah.

Nevada. G. G. Schwois (May 19): Alfalfa aphids were reported as severely
damaging -alfalfa in western vada on May 19.

Oregon. MI. M. Reehor and L. P. Rockwood (May 21): Sone fields of early
fall sown vetches and Austrian winter field pcas were seriously
damaged throughout the Willamette Valley, in northwestern Oregon,
late in April and early in MIay. By M.'v[ 12 aphids were chocked
severely and almost elininated by a fu--:.-us disease. Deficient
precipitation since 1'ay 12, with very low night humidities on '.'s 13
and 1.4, has checked the spread of these diseases, especially on
Austrian peas, and aphids have increased rapidly. Syrphid eggs and
larvae are becoming abundant. Somno fields seeded about November 1
do not yet show damaging- populations.

California. A. E. Michelbacher (Mlay 20): The pea aphid has been rather
abundant on alfalfa during the entire growin.:- season. It was partic-
ularly bad in the San Joaquin Valley. A brief review of what
occurred follows: If the rea aphid is serious it is usually the
first crop of alfalfa that is injured. This year, although there
was a large population on the first cutting, it was the second crop
that was most seriously injured. In certain fields the population
was large enough to deform much of the alfalfa. In many fields
the population built up to a point where one had to stop sweeping
after taking 50 strokes, because the net became so her.vy with aphids.
This was the condition up to May 10. At thr.t time, in m?.n' fields,
predators anrd a fungus disease b .-g.-n to got the upper hand. In the
survey made on May 19 hardly an -phid was encountered.

THRE-COP.P.ED ALFALFA HOPPER (Stictocerhala festina Say)

Louisiana. L. 0. Ellisor (.ay): First-generation nymphs of the three-
cornered alfalfa hopper are -grg alfalfa in the southern part
of the State.

.ALFALFA WEEVIL (Hypera postica Gyll.)

Utah. C. J. Sorenson (May 19): This pest is doing serious injury in
some fields in Utah County, in northern Utah.

G. F. Knowlton (May 23): Larvae are beginning to injure alfalfa
at Kanosh, in Millard County, and are damaging alfalfa foliage in
one field at Minersville, in Beaver County, both in western Utah.

Nevada. G. G. Schweis (May 13): A survey of fields in Douglas County,
in western Nevada, on May 13 showed no larvae of the alfalfa weevil
present, although the stems contained many eggs. This is unusual,
as ordinarily by May 15 the larvae are very numerous on the plants.

California. A. E. Michelbacher (May 20): The alfalfa weevil is becom-
ing rather scarce over the entire infested region of low land in
central California. A survey of the infested area shows an average
number of individuals collected per 100 swoops of an insect net in
the different fields according to the following range: San Joaquin
Valley, adults 0-184, larvae 0-120; Plcasanton .rea, adults 0-1,
larvae 0-12; San Francisco Bay area, adults 0-3, 1-.zrve 4-55. Most
of the large alfalfa weevil larvae collected wore parasitized by
Bathyplectes. Based on rearing records, the amount of parasiti-
zation over the entire infested area for different fields on May 2
ranged from 95 to nearly 100 percent.

ALFALFA CATPILLAR (Burymus eurytheme Bdv.)

Tennessee. G. M. Bentley (May 24): Reported as found on alfalfa in the
northern portion of Lake County, in northwestern Tennessee, where
it had completely stripped the alfalfa of its leaves.


CLOVER LEAF WEEVIL (Hypera punctata F.)

Maryland. E. N. Cory (April 29-May 6): There is a general infestation,
but reports of extreme damage coming from Cecil, Harford,(north-
eastern counties) and Howard County, in the central part of the

Virginia. P. F. Skofield (May 11): Beetles received from Hampton
Institute, in southeastern Virginia.

Mississippi. C. Lyle (May 24): Adults were received from Mayersville,
in Issaquena County, on April 23, with the report that theywere-abun-
dant around a few alfalfa plants. Other specimens also probably
found on alfalfa were received from Schlater in Loflore County
on Mlay 3, both counties being in western Mississippi.

Kansas. H. R. Ery'on (May 28): Reported as abundant in a lawn at La-
Crosso, in central Kahsas, on May 21, but not doing damage when


CLOVER ROOT BORER (Hylastinus obscurus Marsh.)

Idaho. J. R. Douglass (May 10): A complaint has been received of this
insect infesting clover plants northeast of Jerome, in south-central


CURCULIOS (Chalcodermus spp.)

South Carolina. J. G. Watts (April and May): Scattering specimens of
C. aeneus Boh. have been found on cotton and cowpeas at Blackville,
in southwestern South Carolina. No indications of destructive numbers.

Georgia. T. L. Bissell (May 19): Adults of C. collaris Horn are infest-
ing potted cowpeas set in the field at Experiment, in central Georgia.
First insects seen April 26, a week earlier than noted in 1936 or 1937.

CLOVER STEM BORER (Languria mozardi Latr.)

Louisiana. L. 0. Ellisor (May): From 25 to 35 percent of early planted
soybeans at Baton Rouge, in south-central Louisiana, contain larvae.


.MEAOW PLANT BUG (Miris U1olobrvtus L.)

Kentucky. W. A. Price (iMay 29): This pest appeared in unusual numbers
in bluegrass fields in Fayette, Clark, and Bourbon Counties, in
central Kentucky.

A PYRALID (Nomophilia sp.)

Kansas. H. R. Bryson (May 29): This small grass worm was reported on
April 26 as having destroyed 40 acres of fine bluegrass and wild-
oat pastures at Williamsburg, in east-central Kansas.


SUGARCAYE BORER (Diatraea saccharalis F.)

Louisiana. J. W. Ingrainm, W. E. Haley, and L. J. Charpentier (May 25):
Injury from first-generation borers h.s been heavier than in a
n'uiber of years. Borers of this generation are pupating and some
moths have emerged.

B. A. Osterberger (,ay 23): Infestations are scattered. Very
heavy in February-planted corn in some fields. Parasites (Tricho-
gramnma spp.) vuryZr scarce. Second-generation adults began emerg.
about the middle of May.'. Z-s are scarce.


,SUGARCANE BEETLE (Euotheola rugicops Lee.)

North Carolina. 0. S. Brimley (Hay 31): Boring into bottoms of stalks
on a farm at Sherill's Ford, in the western part of the State,

Kentucky. W. A. Price (May 28): Rough-he,-idd cornstalk beetles did
some damaro to corn in the vicinity of Morgantown, in northwestern

Mississippi. C, Lyle (May 24): Injury to ynung corn and sugarcane
by this insect has been reported from localities scattered over the

Louisiana. W. A. Douglas (Hay 19): Injury to young rice stalks aver-.
aged 2.3 percent for the 1933 season. A total Of 3,500 stalks
were examined in 17 fields and the highest percentage of injury
in any 1 field was 39.6.

B. A. Osterborgor (May): Thesec insects are not so active as
they were several weeks ago. Much canehas ap.,rerntly overcome
noticeable- igns of injury. Ej.- arnd young steg;es are found by
digging in the soil. Few adults are attracted to lights around
Baton Rouge.

FLATHEADED APPLE TREE BORER (Chrysobothris femorata 01iv.)

Massachusetts. E. P. Felt (May 24):' A flatheaded borer (probably C. femorata)
was found to be somewhat prevalent in beech at Hopkinton, in eastern Massa-

Indiana. J. J. Davis (May 23): Flatheaded borer reported attacking Vpple and
maples, both hard and red, from all sections of the State.

Illinois. W. P. Flint (May 23): Reports of damage have been generally very
numerous. Damage to fruit and shade trees has been heavy.

Kansas. H. B. Hungerford (May 23): Borers, both roundheaded (Sapcrda candida F.)
and flathoadod, continue to be unusually abundant, and many shade trees,
damaged by heat, drought, and previous defolia-tion by cankerworms, are dying
from attack by the borers.

Nebraska. M,. 1. Swenk (May 20): Cormplaints of damge by the flatheaded apple
trooee borer were received during the period April 22 to May 7 from Douglas,
Merrick, and Antelope Counties, in eastern Nebraska, and from Dundy County,
in southwestern Nebraska. Trees concerned were chiefly American elm, green
ash, and soft maple.

Oklahoma. F. A. Fenton (May 20): The roundheaded apple tree borer was reported
on apple trees at Red Oak, in southeastern Oklahoma.

FRUIT TREE LEAF ROLL=, (Cacoecia argyrospila Walk.)

Missouri. L. Hasoman (Hay 23): During May the heaviest outbreak in 30 years
developed. Worms began pupating the middle of the month and moths'havo.boon
emerging in the laboratory at Columbia since May 20. i:ost of the larvae
have pupated, though here and there, larvae still only half-grown may be
found. This year they have been attacking the foliage of a very wide range
of trees and shrubs, with an occasional specimen found on herbaceous plants.

THRIPS (Thysanoptera)

Indiana. J. J. Davis (May 23): Thrips (imrmature forms seen, apparently Thrips
tabaci Lind.) were common on sweet cherry leavc2 at Kendallville,in north-
eastern Indiana, on May l6. "They were feeding chiefly at the base of the
crotch of the main veins along the midvoin. The feeding had killed little
areas, which turned brown and dropped out; however, the injury was not con>-
siderod serious.

Pennsylvania. H. E. Hodgkiss (May 25): Thrips on apple leaves are generally
abur.dant and some are apparently curling tender foliage.

AJROPEAN El UITZ (Paratetra.nychue gt1a C.'& i.)

Massachusetts. A. I. Bourne (May 24): Red mite followed very closely the bud
development and appeared at the usual time in relation to bud development

170 -

and leaf growth of apples, although this was considerably earlier than
the normal calendar date of their appearance.
Connecticut. P. Garman (May 20): Pest appearing in considerable numbers in
several large 'apple orchards throughout the State ....

Oregon. D. C. Mote (IMay): European red mites heavier than usual on prunes.


CODLING MOTH (Carpocapsa pomonella L.)

New York. D. W. Hamilton (May 25): Adults were first captured at Poughkoepsie
in bait traps on May- 17. Weather conditions were generally unfavorable
for activity and few female moths were~captured before May 21.. Moths
began emerging from pupae in overwintering cases on May II.

N. Y. State Coll. Agr. News Letter (May): Moth emergence was first
noted at Geneva on May 18.

Pennsylvania. H. E. Hodgkiss'(Ma"- 25): First catches of adults in bait
pails in the following counties in southeastern Pennsylvania : Cumber-
land,on May 3; Adams, on May 4; Delaware, on May 6; and Franklin, on May
9. Emergence was slow, owing to low temperatures until May 17 ih Dela-
ware County. In Adams County there was a heavy catch on May 17, 18,and 19

Delaware. L. A. Stearns (May 26): Approximately 100 percent of the over-
wintered larvae had pupated on May 12; the peak of emergence of spring-
brood moths was on May 7 and 8; nximur.u catch by bait cahs was on May
17; and first injury by first-brood larvae was observed on HIay 17, about
2 weeks earlier than usual.

Maryland. E. N. Cory (May 9): First peak of emergence, following a week of
high temperatures in Washington County, in western Maryland.

Virginia. W. J. Schoene (May 23): The peak of codling moth emergence was
noted on May 2 to 6 at Stuart, and on May 4 to 9 at Roanoke, both in
southwestern Virginia.

A. M. Woodside (May 15): 'Moth emergence began at Staunton in west-
central Virginia, on April 29. An apparent peak in emergence was reached
on May 6 and 7, after which cool weather eheaked emergence. The number
of moths emerging has increased rapidly and is now at. an apparently
true maximum. Eggs began -to hatch on May 15. Oviposition light.

Georgia. C. H. Alden (May 20): First-brood larvae are beginning to leave
the fruit at Cornelia, in northeastern Georgia, but only about 2 percent
of the apples are stung or wormy. A few spring-brood moths are still
coming to the bait pots.

Ohio. T. H. Parks (May 23): Mortality of larvae was very light during the
last winter. Emergence of moths boeah in southern Ohio. on .April 27,

at Columbus on May 3, at Wooster on ma,y 4, and near Toledo on May 16.
Eggs are now co:emnon on apples at Columbus,-'but no larval entrances have
been observed. Heavy frosts on May 12 and 13, with temperatures as low
as 230 F. in a few orchards, slowed up incubation but it remains to be
seen whether eggs were killed.

Indiana. L. F. Steiner (May 11): Emergence and bait-trap captures have
fallen off somewhat during the last week, but the moth population in
unbaited trees was about 10 percent greater than a week ago, the average
at Bicknell being 15 moths. The first hatched c.-;s were found on May 6,
2 weeks earlier than normal. (May 19): From May 10 to 17 development
had been practically at a standstill so that conditions now are only
about 1 week ahead of normal. (May 24): Moth activity in southwestern
Indiana reached a peak on May 3 and another of about equal size on May
19 and 20. Successful entrances in unsprayed orchards are difficult to
find. Counts on May 18 showed that 92 percent of the overwintering
brood had pupated and 95 percent emered.

Illinois. W. P. Flint (May 23): Emergence from overwintering larvae has
been unusually heavy, owing to the high rate of survival. As cool, wet
weather has delayed or prevented egg laying, infestation in unsprayed
orchards at the present time is light.

Missouri. L. Haseman (May 23): Moths began to emerge 10 to l4 days earlier
than normal. In southern Missouri bait traps showed moths on the wing
late in April, the emergence in that part of the State increasing in
abundance until around May 3 or 4. In northwestern Missouri emergence
began around May 3, increasing in abundance through May 10 and 11. In
northeastern Missouri emergence in breeding cages began late in April
but only an occasional moth appeared in the bait jars until May 15 and
16. In southern Missouri worms first began entering fruit about the
middle of May and a week later they were observed in central and northern
Missouri. While there was a considerable carry-over of the pest from
last year, they have found the weather in May very unfavorable for
normal breeding.

Missouri and Kansas. H. Baker (May 21): Moths bean emerging in north-
eastern Kansas and northwestern Missouri in outdoor cages on April 29
and were first taken in bait traps on April 30. This is the earliest
record of emergence for several years. Almost continuous cool, rainy
weather since the first eomcrence has retarded development althou-h
moths have beer. captured in bait traps in large numbers whcnevcr con-
ditions have been at all favorable for their activity. No signs of
larval activity have been observed by the writer, but on May l1 another
observer in central Missouri found entrances, some of rhich appeared to
be 2 or 3 days old.

Kansas. H. R. Bryson (May 29): Lmergence of adults did not tace place
until the middle of May. The last week in May many worn entrances
have occurred where control measures have not been properly taken.


Colorado. G. MA. List (May 28); The first codling moth of the season emerged
on May 4 at Fort C1llins, in north-central Colorado. There has been
very low winter mortality in this section.

J. H. Newton (May 23): The first moth was caught at Paonia, in
west-central Colorado, on May l14.

Idaho. R. W. Haegele (Iay): Codling moth control this season promises to be
more difficult than usual, owing to the survival of large numbers of
worms after a mild winter and also to a light crop.

Washington. E. J. Newcomer (May 19): The first moth was found in baits at
Yakima, in south-..central Washington, on April 25, and the first eggs
were laid in field cages on April 30.

EASTERN TENT CATERPILLAR (Malacosoma americana F.)

Maine. H. B. Poirson (May 12 and 15): First nests appeared at Bar Harbor
on May 12. By May 15 the pest was very abundant in Augusta and vicinity.

F. H. Lathrop (May 17): An egg mass was observed hatching at
Orono in Penobscot County, in central Maine, en April 20. Small, newly
formed nests were nbscrved on apple trees at Monmouth, in Kennebec
County, in the southwestern part of the State, on April 25. The nests
appear to be somewhat more abundant than last year.

Vermont. H. L. Bailey(May 28): Infestation of the eastern tent cater-
pillar is somewhat spotty, but heavy in many parts of the State. The
feeding period is nearly ended, and the larvae are leaving trees to
spin cocoons.

Connecticut. W. E. Britton (May 21): Scarce around New Haven, but more
prevalent in Litchfield County, in northwestern Connecticut. More nests
reported in Tolland County, to the east, than elsewhere. Nests reported
very abundant at Rainbow in Hartford County, in the northern part of
the State.

New York. J. V. Schaffner, Jr. (May 23): Caterpillars are causing con-
siderable concern in Broome and Delaware Counties, in south-central
Now York. The wild cherry and apple trees along fences and rural high-
ways arc heavily infested.

Maryland. E. N. Cory and staff (May 24): Heavy infestation on apple, cherry,
and other trees in Dorchester and Somerset Counties on the Eastern Shore.

Georgia. T. L. Bissell (May 9): First moths caught in light trap at Ex-
periment, in central Georgia, on April 30.

GREEN FRUITWORM (Graptolitha antennata Walk.)

New York. N. Y. State Qoll. Agr. News Letter (May): The green fruitworm
is injuring apple to sode extent in the Hudson River Valley.

- 173 -

Indiana. L. F. Stoiner (May 24): This post has booeen more abundant at Vin-
cennes than at any time in the last 5 years, and its damage is con-
spicuous in some orchards.

PISTOL CASEBEARER (Colcophora malivorella Riley)

Maino. F. H. Lathrop (May 17): Small casebearers, recently emerged front
hibernation, were observed attacking developing apple buds on 1: .- 3 at
Monmouth, in Konnebec County.

Pennsylvania. H. E. Hodgkiss (:Ia.- 25): Damage very severe in two apple
orchards in Adams County, in southern Pennsylvania.

Virginia. W. J. Schoeno (May 23): Reports from Winchester, in northern
Virginia, that the pistol casobearer is more abundant than for several

APHIDS (Ap:.iidao)

Maine. F. H. Lathrop (MIay 17): Newly hatched nymphs of the apple aphid
(Aphis pomi Deg.) were found on apple buds on April 25 at Mon-iouth, In
Kenncbeb County. This is about 1 week ahead of hatching last year.
Stem mothers began producing young on May 15, only a day or two earlier
than last year.

Massachusetts. A. I. Bourne (May 24): Winged migrants of the apple grain
aphid (Rhopalosiphum prunif6liae Fitch) being found at present, the
first of these noted before May 13.

Connecticut. P. Gar-ianu (May 20): Rosy aphids (A.nuraphis roseus Baker )
present in most apple orchards in New Haven County, bocoiing abunrnt
in a few. Early season dry periods have not permitted extensive de-
velopment in most orchards.

New York. N. Y. State Coll. Agr. News Letter (:y): The fruit aphids are
causing only a moderate amount of damage generally over the State.

Pennsylvania. H. E. Hodgkiss (May 25): Rosy apple aphids are abundant in
some orchards, curling leaves and infesting fruit clusters.

New Jersey. T. L. Guyton (June 1): Very numerous on unsprayed host trees
near Bound Brook, in north-central New Jersey.

Delaware. L. A. Stearns ('1ay 16): General infestation of the rosy P-mmle
aphid, which is severe, especially in orchards where control neacures
have been omitted.

,aryland. E. N. story (May 13): Two lots of rosy apple aphids sent in, one
from Cambridge and one from Baltimore, both accompanied by numbers of
larvae of the ladybird beetle and the syrphus fly. Woolly aphids
(Eriosora- lanigerum Hausm.) reported generally on apples.

- 174 -

Virginia. A. M. Woodside (May 21): Two weeks ago predators of the rosy
apple aphid seemed to have the situation well in hand, but most of
these have pupated and the aphids are multiplying rapidly. Damage in
some orchards will be from light to moderate.

H. G. Walker and L. D. Anderson (May 25): Aphids were Tory abun-
dant during the latter part of April and the first part of May on a
few apple trees growing on the grounds of the Virginia Truck Experi-
ment Station at Norfolk.

Georgia. C. H. Alden (May 20): Green apple aphids are abundant in most
apple orchards in the State.

Mississippi. C. Lyle (May 24): Injury to oats by the apple grain aphid
was reported on May 7 from Glendora, in Tallahatchie County, in north-
western :ississippi.

Indiana. J. J. Davis. (.ay 23): The rosy apple aphid has been very
abundant on and destructive to apple, especially in the southern half
of the State. The natural enemies are just now beginning to make some
headway against them.

L. F. Steiner (:.vy 9): Rosy apple aphids are conspicuous on many
trees. Migration and natural enemies have greatly depleted the aphid
population on apple trees. (y 11): Rosy and green aphids are still
very abundant in western Indiana, with the former predominant and still
causing severe injury. The effect on the fruit is already very notice-
able. Natural enemies are increasing very slowly. The woblly apple
aphid has been very active on twigs injured by the 13-year locust last
season. (May 24): The damage done by rosy apple aphids is the most
severe that has been observed in southwestern Indiana for several years.

Missouri. L. Hasonan (May 23): During May orchards have been more severely
infested by the rosy apple aphid than fo- many years. At Columbia the
peak of development of the pest came around May 10 to 15, but they are
still abundant. Notwithstanding the cool, rainy weather, predators and,
to a loss extent, parasites have been helping to reduce the infestation.

Washington. E. J. Newcomer (May 6): The green apple aphids are more
numerous than usual at Yakima. Ladybird beetles, mostly Coccinella
quinquenotata Kby., arc also very numencrous and 18 egg clusters were ob-
served on 1 limb.

WHITE APPLE LEAFHOPPER (Typhlocyba pomaria M'cAtee)

Connecticut. P. Garman (May 20): Either late in appearing or less abundant
than usual in New Haven County.

New York. N. Y. State Coll. Agr. News Letter (May):' The first nymph was ob1-
served in the lower Hudson River Valley on April 29. The first week in
May the insect was hatching generally from overwintered eggs and by
May 9 the larger nymphs wore beginning to acquire wings.

- 175 -

Pennsylvania. H. E. Hodgkiss (May 25): White apple leafhopper hatching
rapidly. During the week of May 15, these were plentiful up to and
including 3d-instar individuals.

Virginia. A. M. Woodside (May 21): Nymphs are common in some orchards
around Staunton and adults are beginning to appear.

NEW YORK WEEVIL (Ithycerus novoboracensis Forst.)

Massachusetts. A. I. Bourne (May 24): A rather severe infestation was
reported within the last few days. The insect has shown itself to be
very abundant and is causing considerable da.nage in a young apple
orchard adjoining a strip of woodland. Injury caused by this beetle
last year was not extensive. This year, however, the insects are very
abundant and hWve already caused considerable damage to young growth.
This is interesting, as this insect is seldom abundant enough to cause
appreciable damage.


PLUM CURCULIO (Conotrachelus nenuphar Hbf,.)'

Maine. F. H. Lathrop (May 17): A very few individuals have emerged in
experimental emergence cages. A period of cold rains during the last
2 weeks has delayed emergence around Monmouth, in Kennebec County.

Massachusetts. A. I. Bourne (May'24): Plum curculio has been considerably
delayed in coming out of hibernation and appearing in the orchards be-
cause of the slightly cool weather this last week or 10 days.

Conneattcut. P. Garman (May 20): No damage yet seen from this insect in
New Haven County. Stage of tree development appears to be much fur-
ther advanced than that of the insect.

New York. N. Y. State Coll. Agr. News Letter (May): Plum curculios began
emerging in the lower Hudson River Valley during the first week in ",r
and by the middIS of the month were reported as abundant in several

Pennsylvania. H. E. Hodgkiss (May 25): Unsprayed peach orchards show
approximately 75 percent of the fruits cut by plum curculio. Adults
are plentiful, feeding and laying eggs. No hatching of eggs observed.

Delaware. L. A. Stearns (May 26): Peak of activity of overwintered adults
as determined by jarring in Sussex County, in southern Delaware, on
a:,; 12. Peach drops now generally infested with mature, first-brood
grubs. Partial second brood seems certain if the present favorable
weather conditions continue.

Virginia. W. J. Schoene (May 23): Plum curculio adults are still deposit-
ing large numbers of egs in the peach orchards in Albemarle County, in
north-central Virginia, and many of the larvae are leaving the fruit.

- 176 -

A. M. Woodside (May 21): Overwintored adults of the plum cur-
culio were more abundant in peach orchards of the Crozet section, in
Albomarlo County, this spring than since 1930. Larvae began to leave
dropped fruit on May 7. Most infested fruits in orchards that were
sprayed and jarred had dropped by May 15. Adults in the insectary arc
still depositing largo numbers of eggs.

Georgia. 0. I. Snapp (May 14): At Fort Valley, in central Georgia, 3,375
larvae were reared from 1 bushel of peach drops collected on April 13.
This represents an infestation of about 42 percent, which is the maxi-
muizi infestation. The average infestation will be considerably lighter
than this. (May 20): The first plun curculio pupation of the season
was recorded at Fort Valley on May 6, which is exactly 3 weeks earlier
than the first pupation last yoar. Pupae of the first generation had
transformed to adults in the soil by !May 20, but there had been no
omerr--o:ce of now beetles by that date. Caie and jarring records re-
vealed the fact that most of the overwintered adults had died by May
l1. The curculio infestation at Fort Valley is now lighter than that
of an average year, which is doubtless due to the lighter than usual
carry-over from last year, perhaps the lightest in 1S years,

C. H. Alden (May 20): The grub infestation was so light in the
northern section of the State that many of the growers did not pick up
drops. The peaches in the orchards to date remain practically free of

Mississippi. C. Lyle (Mlay 24): Considerable injury on unsprayed peach trees
is reported by J. Hilton, of Jackson; M. L. Grimes, of Meridian; and
N. D. Poets of Brookhn-'ven, in the eastern and southern parts of the State.

Louisiana. W. F. Turner (May 16); Ourculib weote fomd to Ib prerint il
considerable numbers in Bossier Parish, in northwestern Louisiana, on
M.a:- 10, when jarring was tried.

Arkansas. W. F. Turner ( 1[y 16): Discussion with various growers in the
Nashville area, which includes parts of Howard and Pike Counties, in
southwestern Arkansas, brought out the fact that in some orchards there
is a much heavier infestation than has occurred in the area since 1929.
Orchards that -,avo received uniformly efficient control measures during
the last several years are very lightly infested and the infestations
are confined to the areas near possible hibernation quarters.

ORIENTAL FJIT M.OTH (Grapholitha molosta Busck)

DelaWare. L. A. Stearns (:ay 26): Approximately 100 percent of over-
wintered larvae pupated by April 25; peak of enmer-ence of spring-brood
moths on April 20 and 21; first twig injury by first-brood larvae ob-
served on May 4 and at its height by May 20.

Virginia. A. M. Woodside (M'ay 21): EB!ergence of the spring brood of oriental
fruit moths is complete in the Staunton district. Twig infestation is
high, although premature hardening of twigs has ctuscd many of the worms
to enter fruit. No first-brood moths have been observed.

- 177-

Georgia. 0. I. Snapp (Hay 14): Moths of the first full r-eneration of 1938
at Fort Valley are now emerging. The infestation is light, or about
as usual at this season of the year.

C. H. Alden (May 20): More abundant than last year near Cornelia
and several orchards, especially where there are plantings of your_--
trees, are showing considerable twig injury.

Tennessee. G. M1. BentJ9y (May 24): Oriental fruit moth reported infesting
peaches very heavily at McMinnville, in Warren County, in central

Mississippi. C. Lyle (Hay 24): Peach twigs injured by the oriental fruit
moth were received from Hazlehurst, in Copiah County, in southwestern
Mississippi, on May 16.

Indiana. L. F. Stciner (May 19): Twig dama-c is less than normal at this
sta-e of development in southwestern Indiana.

Illinois. W. P. Flint (May 23): This insect has appeared in rather large
numbers in many localities in southern Illinois. The second brood is
just coming on.

PEACH TWIG BORER (Anarsia lineatella Zell.)

Colorado. J. H. Newton (May 10): Overwintering brood of larvae nearly
mature and causing injury to new growth and fruit in apricot orchard
near Paonia in the west-central part of the State.

PEACH BORER (Conopia oxitiosa Say)

Connecticut. P. Garman (May 20): Severe infestations seen in several peach
orchards in Now :aven County, causing more damage than usual.

Virginia. A. M.' Woodside (o:y 21): Pciech borers seem to be unusually
abundant in the Staunton district.

Georgia. 0. I. Snapp (Ma' 19): Poach orchards in the vicinity of Fort
Valley have been examined for cocoons, but there has been no cocooning
or pupation to date. The first cocoon of the season last year was
found on Hay 23. In 1936 moths wore crcerging by May 8.

Mississippi. J. Milton (:May 24): Injury to peach trees in Hinds County,
in southwestern Mississippi, was reported on Mty 23.

BLACK PEACH APHID (Anuraphis persicac-niger Smith)

Delaware. L. A. Stearns (May 26): Abundant over the entire State on peaches
and observed on grapes at Farmington, in Kent County, on May 24.

Virginia. A. M. Woodside (May 21): Infestation has been severe, particular-
ly on young trees, in the Staunton district. In a few orchards the
infestation on mature trees has been so severe th.t it was necessary to
apply a pray for control.

- 179 -

TWashin.-ton. E. J. Newcomer (May 25): Reported from Yakima on young poach
trees, just sot out. Apparently numerous enough to prevent trees from


PEAR PSYLLA (Psyllia pyricola Foorst.)

Connecticut. P. Garman (l'ay 20): Reported from New Haven County on pear.
Rather loss abundant than usual at the beginning of the season.

New York. N. Y. State Coll. Agr. News Letter ('ay): In the lower Hudson
River Valley all states of the nymphs were common by the middle of the
month. By the last of the month most of the eo:s had hatched in
western New York and a large percentage of the nymphs wore in the
hardshell stare.

PEAR BORERP (Conopia pyri Harr.)

Virginia. A. I1. Woodside (I'ay 21): Adults of the pear borer are appearing
Generally in considerable numbers in bait pails in apple orchards in
the Staunton district.

PEAR THRIPS (Tacniothrips inconsoquens Uzol)

Oregon. D. C. Mote (M1ay): Injury reported as serious in some 7il,111ette
Valley orchards. Eiercnce on March 9, oTylpogitlon on April 6, and
hatchin- about April 15 in Umpqua Valley. Hatching on April 20 in
Willamotte Valley. Not numerous in Umpqua Valley and abundance spotted
in Willanmtto Valley.


C =RZY LEAF K':I:TER (Profonusa collaris MacG.)

Pennsylvania. E. P. Felt (May 24): Reported as somewhat abundant in the
Philadelphia area.

Maryland. E. P. Felt (:!a,: 24): Reported as somewhat abundant in the Center-
ville area, on the Eastern Shore.

BLACK CFP2.Y APHID (lyzus cerasi F.)

New Jersey. T. L. Guyton (June 1): Reported attacking: cultivated cherry at
Bound Brook, in north-central 'iew Jersey.

Utah. 5. F. Knowlton ('lay 11): Bc-.innin: to curl cherry foliate in parts
of Davis County, in northern Utah.

- 179 -


RED-NECKED CANE BORER (Agrilus ruficollis F.)

Virginia. C. R. Willey (April 25): In an infestation at Richmond about
twoothirds of the canes were affected and at least half were either
dead or badly wilted. An extremely hot spell for 2 days caused the
canes to go down rather rapidly. About 80 percent of the larvae had
pupated and were located 5 to 6 inches above the gall in the cane.
This was the worst case of this pest I have seen.

RASPBERRY FOUIITWORY (Byturus unicolor Say)

Now York. N. Y. State Coll. Agr. News Letter (May): This insect is abundant
in raspberry plantings in the lower Hudson River Valley.

Washington. W. W. Bakeor and B. J. Landis (May 17): Reported attc'k:inr
raspberry, lo,;anberry, and bush blackberry at Puyallup Valley, in
western Washington. First eggs observed on May 12. Adults found feed-
ing on Rubus spectabilis (salmon-berry) in greater numbers than usual.

RASPB3E-Y SAWFLY (:Ionoophndnoides rubi Harr.)

New York. N. Y. State Coll. Agr. News Letter (May 23): Larvae are very
abundant on the undersides of the young raspberry leaves and are doing
much dLam-o in :Tassau County.

Kansas. H. R. Bryson (May 28): It was reported on May 25 that the rasp-
berry sawfly had booeen causing considerable damqu:e in Droniphan County,
in northeastern Kansas.


AN APHID (Macrosiphum rubiellum harpagorubus Knlt.)

Washington. B. J. Landis and 7. W. Baker (May 17): Reported on evergreen
blackberry from Puyallup. A few alate individuals among the apterous
ones. An adult elaterid and several adults of Adalia bipunctata (L.)
observed feeding on these aphids.

A SCALE I:TSECT (Lecanium coryli L.)

Washington. W. W. Bakcr and C. W. Getzendanor (May 19): Reported on
cultivated Rubus and other plants at Puyallup. Continues to be abundant.
First males observed on April 1.

Michigan. R. Hutson (May 26): Grape leafhoppers are very numerous in
raspberry plantings.

California. G. H. Kaloostian (May 18): Reported from Fowler, in southern
California, in increasing abundance and as worse than last year.

PACIFIC MITE (Tetranychus pacificus McG.)

California. L. M. Smith (May 19): The Pacific mite emerged from hibernation
under the bark of grapevines in San Joaquin County in large numbers
late in March and early in April. In some vineyards from 10 to 15
overwintered females per leaf could be found in the early part of
April, but, owing to an unusual abundance of predators, particularly
mites and prodaceous thrips, the population of mites has been reduced
until, at the present time, none of them can be found in most vineyards
where large numbers were known to have survived the winter.

A MITE (Tetranychus willanettei McG.)

California. L. M. Smith (:a'-ay 18): The Willamette mite has been taken in
several vineyards near Lodi and Escalon. At present severe injury can
be the basal three or four leaves on some canes, whereas the
terminal six or eight leaves show no injury nor infestation. Observa-
tions during the last 2 weeks indicate that the population is decreasing


A MOTH (Tortricidae)

Louisiana. L. 0. Ellisor (May): The larvae of a tortricid, similar in
habits and appearance to the oak ugly nest tortricid (Cacoecia cerasi-
vorana Fitch), defoliated many pecan trees in the town of Opelousas, in
south-central Louisiana, during the latter half of May. This insect
first attracted attention as a pest of pecan in Opelousas 3 years ago
on a limited number of trees, but since that time the infested area has
increased each year, and this year included pecan trees throughout the

PECAN NUJT CASEBEARER (Acrobasis caryac Grote)

Georgia. G. F. Moznotte (May): On May 16 noticed the first cluster of
pecan nuts infested at Albany. From May l1-e larvae were noticed in
greater abundance. In some orchards the insect is practically absent,
judging, from infested clusters,' while in other'orchards as high as 25
percent of the clusters are infested. As a whole, the infestation was
much less than 25 percent of infested clusters up to May 21.

- i11 -

CIGAR CASEBEARER (Coleophora fletcherolla Yern.)

Florida. J. R. Watson (May 23): In Okaloosa and Walton Counties the cigar
cascboarer has been very injurious to pecan, eating out the younn7,
unfollini buds. This' insect has been more or less abundant wherever
pecans are grown in Florida, but in western Florida the injury "va!
particularly severe.

HICKORY SHUCK WORM (Laspeyresia caryana Fitch)

Georgia. G. F. Moznctte (May): On .!ay lS the first moths of the first
generation were bred from phylloxera galls on secaling- pecan trees at
Albany. Although eog.-s wore found on the foliage of budded pecan trees
in orchards, no infested pecan nuts had booeen observed by :- 23. In
several pecan nurseries about Albany phylloxera galls on seedlings
pecan trees are heavily infested.

PEC.i' BUDO1.0TH (Gretchcna bolliana Sling.)

Mississippi. G. L. Bond (:.ay l1): Several reports of heavy damage by pecan
budnoth to trees in southeastern Mississippi that have been topworked
have been received.

PECAU Pi-YLLOXERA (Phylloxera devastatrix Perg.)

Mississippi. C. Lyle (::iy 24): Specimens accompanied by reports of rather
heavy general infestations on pecan trees have been received recently
from the Delta district.

Louisiana. C. 0. Eddy'(M,): Abundant throughout the State.


GR7EE-" CITRUS APHID (Aphis spiraecola Patch)

Florida. H. T. Fornald (May 23): Earlier in the year this pest was not
important in the Orlando district but a very long drought (nearly 3
months now with almost no rain) has given it an opportunity to increase
greatly and do much dnai9c to younr" growth.

CITRUS W7HITEFLY (Dialeurodes citri Ashn.)

Mississippi. C. Lyle (.iay 24): Heavy infestations of this insect on Cape-
jasinoe wore reported from Yazoo and Yalobusha Counties, in northern
Iississippi, recently. A light infestation on Japanese persimmon was
also reported from Harrison County, in the southern part of the State.

CITRUS MEALYBUG (Pseudococcus citri Risso)

Florida. J. R. '7atson (::a:.- 23): These insects have made their appearance
on grapefruit in about the usual numbers for this tine of year.

1g2 -

ITRUS RUST MITE (Phyllocoptes oleivorus Ashm.)

Florida. J. R. Watson (May 23): Owing to the warm and. dry weather rust
mites have been generally abundant the past month.


ESTRUCOTOR SCALE (Aspidiotus destructor Sign.)

Florida. H. Spencer (May 18): This insect is not so numerous in the Miami
and West Palm Beach districts as it was last fall. A very largo nunmbcr
of empty cases of Chilocorus cacti L. indicated that the coccinellid
was a factor of importance in control.


PAPAYA FRUITFLY (Toxotrypana curvicauda Gorst.)

Florida. H. Spencer (May l1): During April and May this fly appeared and
did some dma -e to maturing fruits on last year's plants in the !iani

PAPAYA WIITEFLY (Trialeurodes variabilis Quaint.)

Florida. H. Spencer (May 23): Adults of the papaya whitefly appeared in
the vicinity of Orlando about May 14.


VEGETABLE WEEVIL (Listroderes obliquus Klug)

Georgia. T. L. Bissell (May 16): Veg-etable weevil attacking newly set
tomato plants at Experiment in the central part of the State. (May 23):
Accompanying the vegetable weevil on tomato wore a number of Listroderes
apicalis Wtrh, adults. On some days all of these were apparently dead
as most of them had lost their logs. Heretofore, I had collected one
specimen of this insect at Experiment on February 13, 1936.

Mississippi. C. Lyle (May 24): Considerable damage being done by this in-
sect on garden and truck crops and it was reported as very numerous
during May in many localities in the State.
California. J. C. Elmore (May 10): Reported attacking young tomato plants
in the field at Santa Ana, Orange County.

R. E. Campbell (May l1): Vegetable weevil adults are reported to
be causing considerable dinaie- to potato folia-o at Temocula, in
southwestern Riverside County.

FLEA BEETLES (Halticinae)

New York. Ni. Y. State Coll. Agr. News Letter (.May 9): Flea beetles re-
ported front Nassau County on May 2, on tomato plants recently sot out.
The leaves showed considerable evidence of their feedin-.

Pennsylvania. H. E. Hodgkiss (May 25): Field corn in York County, in
southeastern Pennsylvania, is reported to be seriously injured by this

Virginia. A. M. Woodside (May 21): Flea beetles are dannainr beans in
-ardcns in the Staunton district.

bage plants near Walla Walla, in southwestern Washington, where they
were eating out the hearts of the plants so as to prevent the formation
of heads. They were also damaging the leaves of young turnips, which
would eventually result in the death of the plants.

part of the State. The adults have already seriously checked the
growth of spring beans whore no control methods have been practiced.
No larvae have been observed.

South Carolina. J. G. Watts (May)i The bean beetle has boon observed in
larval and adult stages at Williston, Blackville, and Charleston, in

Ohio. N. F. Howard (May 5): One adult of this insect was taken at Columbus
on April 30. Several eg- masses were found at South Point on YMay 5,
indicating that beetles had left hibernation at least 12 days previously.
This is probably the earliest record for that latitudle. (May 23):
Cool weather and frequent heavy rains at South Point have retarded
reproduction of the beetle and have aided materially in control.

Alabama. J. M. Robinson (May 19): Has appeared at Auburn and tho larvae
of the first generation are in the last instar.

Mississippi. .0. Lyle and assistants (May 24): Reports from the eastern

lest this post extend to tobacco, commonly attacked in scattered fields
by H. cilicrura Rond.

Pennsylvania. H. E. Hodgkiss (May 25): Adults were laying eggs abundantly
but none were hatched on May 12 in the southeastern counties.

to early cabbage in the southern part of the State.

CABBAGE SHOOT WEEVIL (Ceutorhynchus assimilis Payk.)

Washington. H. J. Forscll (May 26): Reported on cabbage and turnips from
the western part of the State. The threatened dainac of this pest for

throughout southern Dela':'7arc.

Maryland. E. ". Cory (:!ay 24): First report received on April 25.
General infestation over the State, although not doing serious damage
in northern iiaryland along the Pennsylvania line. The infestation has
been very heavy, with continuous migration from clover, and continuous
breeding, notwithstanding careful spraying and dusting. The infestation
on the Eastern Shore has been accompanied by mosaic, and the two will
probably result in a heavy decrease in the crop.

Virginia. H. G. War.lkcr and L; D. Anderson (:!-y 24): Most of the early
peas in Norfolk and Princess Anne Countics matured without being
appreciably injured by the pea aphid. However, several late fields of
peas and several fields of broad beans have been very seriously in-
jured by this pest in these two counties. Although the pea aphid was
not as destructive in Northampton and Accomac Counties as last year,
it caused considerable injury where control measures were not applied.
The injury was apparently more severe in the northern part of Accomac
County than farther south.

Wisconsin. J. E. Dudley, Jr. (May 4): Aphids increasing rapidly in Iadison
and vicinity. There is evidence that &'flight is in progress from the
southwest, as unusually large numbers of late forms are present.
(May 20): Aphids are slowly increasing in alfalfa. Infestation is
still light. E-irly planted Alaska peas very lightly infested.

Mississippi. J. ,Milton (May 24): English peas heavily infested with
aphids in MHadison County, in west-central Mississippi.

North Carolina. W. A. Tho:--s, (:ay -10): Adults are much nmoro numerous
this season than last. Some d-,i --e is bcinw done to young melons,
which is rather unusual for the Chadbourn a:'co, as these insects
rarely show up in a''ru--d^ice until late in July.

at lights at Expcrinent.

Ohio. N. F. Howard (nay,): Large numbers of striped cucumber beetles were
observed on volunteer squash plants that had cone up in a plowed field
at Columbus, owing to the very early spring. They wore so niumorous
that the s-.all squash plants had beeoon almost devoured when discovered
on May 5. On the same day reports from South Point indicate the
cucumber beetle as being extremely numerous and injurious to early
cantaloups and cucumbers. Petals had fallen from apple and other
fruit several days before the beetles were discovered. Undoubtedly
the beetles had been forced to leave the blossoms 2 weeks or more
earlier than usual.

Mississippi. C. Lyle (:l:, 24): Heavy infestations on cucumbers, melons,
and other crops were observed in Harrison, Jackson, Laudcrdaloe, and
Tate (northwestern' ississippi) Counties. The heavios.t infestation
in several years is present on cucumbers in the vicinity of Wiggins,
Stone County.

Louisiana. L. 0. Ellisor (Mlay): The striped cucumber beetle is very
abundant on cucumbers and melons in southern Louisiana.

Missouri. L. Hrsc-an (,May 23): This beetle was first observed at Columbia
as fruit trees began to come into bloom ahead of the early April
freeze and beetles in scattering numbers .a'-t boon observed almost
continuously since that time but, with very little gardening under
way to date, there have been practically no reports of the beetle on
cucumbers and related crops.

fields near Denver on May I1.

Utah. G. F. Knowlton (May 4): Adults and e!.-s abundant in one field- of'
asparagus at Merriott in Weber County, and are present in a field south
of Sunset. (May 26): Adults and Er-c are abundant on asparao-^is at
Clexarfield and Sunset, but larvae are scarce.

Washington. C. W. Getzendaner (May 10): The asparaaus beetle attracts
more attention each year in the Puyallup Valley in west-central

M. H. Hatch (May 25): This species has within the last few days
occurred at Renton and Bothell, this being the first occurrence this
far north in western Washington.

New Jersey. J. B. Schmitt (May 24): The carrot weevil is doing consider-
able dnmale to celery on the muck area in Bergen County, in north-
eastern New Jersey, and is injuring carrots as far south as Vineland.


OUION TIIHRIPS (Thrips tabaci Lind.)

Connecticut. N. Turner (May 23): A few nynhs and many adults on 10
acres of sot onions in Hartford County. More thafn usual are present
for so early in the season.

Virginia. H. G. Walker and L. D. Anderson (May 25): Onion thrips are
beginning to appear on onions in rather injurious numbers in the
Norfolk area. Some fields of cabba:-e are becoming rather heavily
infested with what is probably the onion thrips.

Florida. J. R. Watson (Mr-y 23): Thrips have been unusually injurious,
including the onion thrips on onions, owing to the unusually hot and
dry weather of the last month.

Mississippi. C. Lyle (May 24): Several reports recently from southeastern
Mississippi of heavy infestations of thrips on onions.

California. J. Wilcox (May 4): The tops on one 4-acre field of large
onions at Artesia, in southern California, show severe damage and the
grower estimates that most of the crop will be lost. A 4-acre field
of younger onions, although not showing much damnage, is heavily in-

Geor;es and Somerset Counties.

- 197 -

Virginia. L. D. Ainderson and H. G. Walker ('May 25): Since our observations
on April 15 the strawberry vcevil became quite active in a number of
strawberry fields in the northern part of Acco-.iac County on the
Eastern Shore and has cut out about 60 percent of the buds in sever!-l
of the fields Although these weevils only cut about 15
percent of the buds in a strawberry field at Onloy, in Acconac County,
they cut over 90 percent of the buds in a small planting 6f dewberries

North Carolina. W. A. Thomas (May 20):. The new generation began cner-i'ng-
from the -upal vtn,'e the latter part of the first week of M.y in the
Chadbourn area. This is arj'.rox:i:..-.tely 2 weeks earlier than usual.

Suffolk County, in eastern New York, that stra'.borry leafrollors were
noted in a strawberry plantation on May 2.

Indiana. J. J. Davis (M.ay 23): Strawberry leafroller was quite abundant
and destructive the last 2 weeks at Xnightstovn. and Gary, in eastern
and northwestern Indiana, respectively.

Kansas. H. R. Bryson (May 29): Strawberry leafroller is more
abundant in northeastern Kansas than for several years and is causing
severe injury. Reported injuring strawberries at Grantsville.

at Riverdale and Providence, in northern Utjt.

APHIDS (Aphiidao)

Virginia. H. G. Walker and L. D. Anderson (May 25): A strawberry fiold
near Norfolk was found. to be heavily infested with the stravwbecrry root
louse (Aphis forbesi Weed). Many of the plants have been killed and
the others are sick and unthrifty, owin- to the injury caused by this
pest. Ants are abundant in this field where they are attcr.,i!-.- these
aphids and the ants have honeyrcornbd the ground around the roots of
the infested plants.

- 193 -

Oregon. D. C. Mote (May): Aphids reported common in all stages on straw-
berries in the Willanetto Valley.

COM1O1N RED SPIDER (Tetranychus telarius L.)

Virginia. H. G. Walker and L. D. Anderson (May 25): These posts con-
tinued to be abundant and to cause considerable damaTe in a number of
strawberry fields in Norfolk and Princess Anne Counties in May.

North Carolina. W. A. Thomas (May 14): The red spider continues to give
considerable trouble to the berry growers in the area around Chadbourn.
'Some of the fields have boon so seriously affected that no efforts
will be made to carry the plants over, but they will be turned under
as soon as the pickin:- season is over. Control measures are being
employed by a few crowers.

Mississippi. C. Lyle (May 24): Strawberry plants heavily infested with
these mites were sent in on May 10 from Moselle, Jones County, in
southeastern Mississippi.


EP2FER WEEVIL (Anthononus eugenii Cano)

California. J. C. Elmore (Hay 11): The pepper weevil is more numerous
than usual on black nightshade (Solanum nigrun). Larvae and pupae are
common in nihtshade berries on the ground in the Bellflower district,
in southern California.


HOP FLEA BEETLE (Psylliodos punctulata Molsh.)

Utah. G. F. Knowlton (May 4): Danagc to sugar beets has been observed
at Farr West, Hot Springs, and iMcrriott, in Weber County. (May 10):
This insect is d:ma-ing sugar beets at Mapleton and' Woods Cross.

H. E. Dorst (::.y 28): The hop flea beetle population on sugar
beets in northern Sevier Valley averages about 3 per square foot, as
compared with 15 to l1 in 1937. No damage has booeen observed. Some
damage is noticeable on young sugar beets noer Garland and Corinne,
where the population avera-es about 16'per square foa* oft'bbet row.
The long distance movement of beet leafhopper into Sevier Valley
averan-es in population about l1 per 100 square feet of boots, as
compared to approximately 300 per 100 square feet in 1937. A few
migrants wore found as far north as Lehion on May 26. The movement
of the pest from the local breeding areas and northern Utah started
on May 27.

TOBACCO F.EA3EETLE (Epitrix parvula F.)

Maryland. E. N. Cory (May 24): The tobacco fleabeetle was reported doinr-
serious damage to tobacco beds in Annoe Arundel, Prince Georves, and
Charles Counties, in central and southern Maryland.

South Carolina. N. Allen, J. W. Hunphreys, and D. B. Lieux (May 23):
Injury to plants in tho field in Florence, Marion, and Horry Counties,
in northeastern South Carolina, has been less severe than in 1936 or
1937, owing apparently to fewer beetles and to more favorable weather
conditions for plant growth at transplanting time. On May 17 a brood
of newly cner,-ed beetles was severely injuring plants in plant beds,
although transplanting to the field was practically complete.

Tennessee. G. M. Bentley (May 24): Reported as attacking tobacco at
Clarksville, in northwestern Tennessee.

L. B. Scott (May 19): The tobacco flea beetle was normally
abundant in tobacco plants in the north-central region but has not
ajrppeared in normal nunmers on transplanted tobacco. Continued cool,
wet weather in May probably interfered with their activities.

GREEN JU=T BUG (Cotinis nitida L.)

Pennsylvania. H. E. Kodgkiss (May 25): Grubs of this pest were causing
severe injury to tobacco beds in Lancaster County on May 13.

TOBACCO 'BUDWO0J.: (HIeliothis virescens F.)

South Carolina. 1. Allen, J. W. Humphreys, and D. B. Lieux (May 23): The
first budworm larva was observed in Florence County on April 25. During
the first week in May, when the plants were just becoming well estab-
lished in the field, infestations were sufficient to require control
measures. This is unusually early for budworm infestation in the field.

Florida. F. S. Chamberlin (May 11): Infestations of the budworm in tobacco
fields in Gadsden County, in western Florida, appear to be about normal.

iOS2 ^ORIS (Protoparce sp*)

Maryland. E. N. Cory (...y 1): Large numbers of pupae being turned up by
plows in last year's tobacco fields. Infestation seems to be heaviest
in Anno Arundel and Charles Counties.

South Carolina. N. Allen, J. W. Hu::phreys, and D. B. Lieux (M:,- 23): The
first hornwori o.-. s wore observed on i'ry 4 at Florence. By May 23
hornworn larvae were sufficiently abu-.dn-int to warrant control measures.
The infestation is abnormally severe for this early in the season.


- 200 -

CO I ROOT E3B7ORI (Crambus caliinosellus Clem.)

Tennessee. L. B. Scott (May 19): The corn root webworm is very prevalent
in north-central Tennessee in soil that had not been worked for 2
years or more. Damage is very severe, reaching 100 percent in un-
treated fields.

GARDEN FLEA ":CPER (Halticus citri Ashmn.)

Florida. F. S. Chamberlin (May 23): The garden flea hopper continues to
be unusually abundant in crops of shade-grown tobacco in Gadsden County.

some damage to shade-grown tobacco in Ga..sdon County.


BOLL W7EEVIL (Anthonomus grandis Boh.)

South Carolina. J. G. Watts (March, April, and May): Taken in very small
numbers at Blackville, in southwestern South Carolina, in late March,
and in April and May. The first were taken on Mlarch 23. found
on cotton.

F. F. Bondy (May 30): Counts at Florence, in the northeastern
coastal plain, indicate that -there are large numbers of boll weevils in
cotton fields, as many as there were last year and more than in 1935 or

Georgia. P. .. Gilmer (May 22): At. Tifton, in southern Georgia, drought
and cool weather have delayed weevil emergence from hibernation and
growth of cotton during- the last few wve.oks. Although weevils have
diminished in the fields, there are enough to cause severe injury.

W. L. Lowry (May 28): Weevils are plentiful in most fields of
Sea Island cotton in Lov.-ni-es and. Echols Counties, in southeastern
Geor--i-.. Punctured squares are evident and full-grown larvae were
found during the week. Weevils are scarce in the few fields where
the stalks were destroyed early last fall and the fields cleaned up.

Florida. C. S. Rude (Iay 21): Showers have started the cotton squaring,
and weevils in the fields have increased at Gainesville and in northern
Florida. (M.ry 28): Weevils are more abundant than during recent years.

Louisiana. B. A. Osterberger (May 24): Boll weevils reported attacking
very small squares in some of the plots at the University Farm at
Baton Rouge, in south-central Louisiana. This is the first record of
adult boll weevils reported to the Department.

- 201 -

R. C. Gaines (May 27): At Tallulah, in Madison Parish, north-
central Louisiari,, more weevils were taken and more found in the field
during the latter part of M1ay than last year, despite the fact tohat
emraergencoe from hibernation caFes has been lower.

Texas. F. L. Thomas (May 20): Boll weevils have been found in four of
five fields examined in Hidalgo County, in southern Texas. A maximum
infestation of 10 percent was found in one field. In Nueces County,
in southeastern Texas, an 8-percent infestation was found and in
Brazes County, in the eastern part of the State, lar:e numbers of
weevils were counted in a field of newly chopped cotton. (M.ay 25):
The infestation in Hidalgo County doubled during the last week
and now averages 12 percent, with a maximum infestation of 24 percent
of the squares punctured. All fields e:xr:i.ed found to be infested.
Approximately 400 weevils per acre found in cotton of presquare a:c
in fields of 13razos, Jackson, and Victoria Counties, in eastern and
southeastern Texas.

K. P. Ewing (May 14): Eight percent of the squares were infested
in one field exa.-inecd near Odem, in southeastern Texas. No other
weevils were found in the vicinity or at Robstown, in Nueccs County.
(M'ay 28): Weevils are abundant in fields in the Lavaca River bottoms,
Jackson County. An average of 4.59 weevils per 100 plants, or over
800 per acre, were found in the 13 fields examined this week. Weevils
are scarce in open-prairie sections of Calhoun County', in southeastern

R. W. Moreland (May 28): There Las been an onercence from hiber-
nation cages of 3.75 percent to date, as cor.pFircd to 5.25 percent in
1937 and 2.04 percent in 1936 during the same period, at College
Station,, in eastern Texas. Weevil populations in the fields examined
are practically the sano as last yo-cr.

SALT-MARSH C.ATLILLAR (EstigCmene acraea Drury)

Georgia. S. B. Penne (:.ay): This outbreak at Vienna it Dooly County, in
douthwoetorn Georgia, is the second severe one reported from this
State. The other was near Danalsonville, Seminole County, in the
same part of the State.

Texas. F. L. Thomas (May 25): Salt-mrarsh caterr)illars are reported to
be causing some injury to cotton in southern Te:xas.

K. P. Ewing (:.I'y 21): 'Many fields of cotton in Calhoun County
(Gulf coast area) were infested with salt-marsh caterpillars. (1.y 28):
This insect is very widespread over the whole county and many con-
plaints have been received of danm.age to cotton and vegetable crops.
Infestation is more widespread than noticed before.

- 202 -

*COTTON LEAF WO770M (Alabama argillacea Tbn.)

Texas. F. L. Thomas (May 25): Reports from Nueces and Calhoun Counties
indicate that some of the early appearing loaf worms are f"webbing up."

K. P. Ewing (May 20): The first cotton loaf worm, about one-
third grown, was found on May 2 in Calhoun County in stubble cotton.
This is the earliest record in recent years. Three full-grown larvae
and an empty pupal case were found today on cotton in Calhoun County,
indicating the appearance of the second generation. (Hay 29): Only
one additional infestation was found this week. This makes a total of
four infestations found in Calhoun County, and one in Nucces County.
PINK BOLL OR2JI (Pectimophora gossypiella Saund.)

Texas. A. J. Chapnn (May 21): At Presidio, in the Big Bend area, the
emergence of moths in the hibernation c.-:es was much higher during
May last year than for the sane period this year. There is an un-
usually lar-::e amount of "Zoca" cotton, which is squaring and blooming
profusely and is heavily infested. This will serve to build up the
population that will later migrate to cultivated cotton. (May 29):
It appears now that the peak of emergence from hibernation is over.

COTTON FLEA .OPFE'R (Psallus seriatus Reut.)

Mississippi. R. L. McGarr (May 28): Flea hoppers in the vicinity of
State College, northeast of the central part of the State, increased
from 0.5 per 100 plants on May l4 to 5.0 per 100 plants on May 2g.

Louisiana. R. C. Gaines (May 29): At Tallulah, in northeastern Louisiana,
sweepings of evening primrose and other wced' hoets. indicate ha&t flaa
hoppers are much loss abundant than last year.

Texas. F. L. Thomas (May 6): Flea hoppers are increasing on their pre-
ferred wooeed host plants in south-central Texas, as cotton is at present
too snail to be attractive. watching is general in-northern Texas.
(May 13): The hatch of flea hoppers to date from croton weeds collected
in eight counties of south-central Texas has been less than avera.;:n,
not only for the first 2 weeks in May but also for the season. The
hatch from similar weeds collected from four counties in northern Texas
and caoed at the Denton substation was twice as grnat during the
last week of April as that in central Texas for the snne period.
(Wia- 20): Flea hoppers are increasing on cotton in the lower Rio
Grande Valley, the coastal areas, and in the Brazes River Valley. They
already occur in sufficient numbers in some fields to justify applica-
tion of control measures. Infestation reached a maximum of 92 per 100
terminal buds at Chapman Ranch in Nueces County. The average flea
hopper infestation in 5 fields examined in Nueces County was 48 per
100 buds. The number of hoppers on horsomint in Calhoun County has
increased almost 100 percent over the previous week. Screen traps in
the Brazes bottoms show that flea hoppers are still entering the cotton

- 203 -

fields to augment the present count of 9 per 100 buds. (May 25):
Screen-trap records in Burleson County, in southeastern Tex:as, in-
dicate that flea hoppers continue to migrate into cotton fields from
native host plants. A slight increase in the population of nynMphs
was noted during the past week.

K. P. Ewing (May 14): The peak of emergence of cotton flea
hoppers from 39 hibernation cages under observation at Port Lavaca
was during the last 5 days of April and the first 4 delays of May,
which is later than ever recorded in southern Texas. The field
infestations shnw considerable increase over previous weeks. On May
13 sweepings made in four fields of horsenint in Calhoun County showed
almost a 100-percent increase over the week before. (May 29): The
flea hopper population in cotton fields in Calhoun County remained about
the sane as last week. Control measures have been necessary in some
fields in Nueces County.

R. W. Moreland (lay 29): At College Station as many as 12 nymphs
per 100 cotton terminals were found in river-bottom fields.

TAERIIS:ED PLANT BUG (Lygus pratensis L.)

Georgia. P. M!. Gilmnor (;ay 2): A few tarnished plant bugs were present
on cotton in the vicinity of Tifton, in southern Georgia.

Mississippi. R. L. McGarr (May 28): At State College a lar-e increase in
the tarnished plant bug population on fleabane and other weeds was
noted this week. The catch icr 100 sweeps was 1,100 adults andcl 2,300

Louisiana. R. C. Gaines (May 2S): Tarnished plant bu's are beconm..rn
abu-;dant on -."ecds in the vicinity of Tallulah, in Iadison Parish.

Arizona. T. P. Cassidy (May 14): The weekly sweeping records in the
Tucson district still show a rather heavy infestation of Lygus spp.
in alfalfa. One field showed 45 per 100 sweeps.


South Carolina. J. G. Watts (May): The first specimens of the cowpea
aphid (Aphis medicaginis Koch) were observed on cotton on A4ril 25.
Since then there has been little rain and, as a result, this insect
has increased rather rapidly. Its nu-bers at present are not serious
but it nay develop into destructive numbers with continued dry weather.

C. F. Rainwater (April 30): The three species of root aphi'ls
(Trifidaphis phasfoli Pass., PRhlopalosiphunm subterraneun "ason, and
Anruraphis mai3Li-raLdicis Torbes) are prccor-t and causing considerable
diaoe to the stands of cotton in Florence County. It war necessary
to replant some fields; in others :-our._- seedlings were adily stunted.

- 2o4 -

A. maidi-radicis was also found on corn and volunteer soybeans.
TMay 28): Root aphids continue to damage cotton. ...

Georgia. P. I. Gilmer (May 22): During the latter part of April and the
first part of May cotton aphids (Aphis gossypii Glov.) appeared in
some numbers at Tifton but at present there are almost none.

Florida. C. S. Rude (May 27): There are a few cotton aphids in some
places near Gainesville, but they are not serious. Parasites seen
to be holding then in chock.

Mississippi. R. L. McGarr (May 28): At State College cotton aphids are
common in most of the cotton fields but parasites and predators are
rapidly reducing their numbers.

Arizona. T. P. Cassidy (May 7): A very heavy infestation of aphids,
which is causing concern to the grower, has developed in a limited
acrcigo of cotton at !irina, Pimna County, in south-central Arizona.
Both parasites and predators are beoinning to appear. (May 28):
Cotton is rapidly recovering from this infestation.

TIRIPS (Thysanoptera)

South Carolina. J. G. Watts (nay 25): The tobacco thrips (Frankliniella
fusca Hinds), the flower thrips (F. tritici Fitch), and Scricothrips
variabilis (Beach) are doing less damage than normal for this season of
the year in Barnwell County, in the southwestern section of the State.

C. F. Rainwator (May 7): The tobacco thrips and onion thrips
(Thrips tabaci Lind.) were causing some local injury to cotton in the
vicinity of Florence the last week of April. (IMay 30): Thrips are
fewer in number because of rains but many cotton fields show severe

Mississippi. E. W. Dunnam (May 28): At Stoneville, in the Delta section,
thrips appear to be fairly abundant in some fields, and some dcbuddinr
has taken place.

Louisiana. C. 0. Eddy (1lay): The flower thrips has been abundant on
cotton for 2 or 3 weeks but there have been few tobacco thrips on
cotton, although this species was destructive last year.

Texas. R. W. Moreland (May 28): In Brazos and Burleson Counties con-
siderable injury has been caused by thrips, but cotton is overcoming
this injury.

CA!KEMRWORI IS (Gconotridac)

Maine. H. B. Peirson (May 15): Spring cankerworm (Paleacrita vernata Peck)
is abundant in Kennebunkport.

New Jersey. C. W. Collins (May 24): Although cankerworms are generally
much less abundant in the vicinity of Morristown than for the last
few years, defoliation of elm and ash by the fall cankerworm (Alsophila
pometaria Harr.) in Chatiam and Florham Park has been reported.

New York. J. V. Schaffncr, Jr. (May 23): In Nassau and Westchestcr
Counties the fall cankerworm is very common. Severe defoliation on
several trees in one locality along the Hutchinson River Parkwva2y was
noticed. Considerable control work is being done in both counties.

Pennsylvania. E. J. Udine (May 21): Unusual numbers of spring cankr.r':orms
are defoliating basswood and oak at :TCville, Cumberland County.

Ohio. T. H. Parks (May 21): The spring cankerworm is .,in injurious in
about 28 western Ohio counties. Complete defoliation has occurred on
some unspraycd farny-.rd apple trees and on elms along stream banks
and in certain areas where the infestation is heaviest. At Columbus
the insect has not caused severe injury but has increased perceptibly
during the last year. In the wooded areas, hickories, ash, hackberry,
and a few other forest trees show the effects of feeding by other
species of spLr.-worms.

J. 1T. Knull (',May 30): Many of the deciduous trees in the section
around Clifton have been badly defoliated by cankerworms.

Indiana. J. J. Davis (M,-,y 23): Spring cnr-'crvorm has booeen unusually
abundant from near Indianapolis,in the center of the State, to the
northern tier of counties. The first reports camec in on My. 7 and
frequent reports have been received since. ach ycar for the last 4,
the reports of cank-rrwvrmn abundance have noted increasing infestation
and spread. The following report on :na. 14 from Wabash is typical.
The reporter recorded the first appearance of the cankerworms on the
elms in one corner of his timber acreage 4 ycarr ago. They gradually
spread until this year they have defoliated all elms in the entire
area and are going over to other trees. The elms stripped of fnlip.-c
4 years ago are nearly all dead.

Illinois. W. P. Flint (Liay 23): Spottcd de:nae-c has occurred over the
northern two-thirds of Illinois, with the most severe dan.-c in the
northwest third of the State. The daman>c is very spotted, a few
cities havi.:- almost all trees infested and other cities and towns
within probably 25 niles showing practically no injury. Si-..-le pieces
of woodland or small areas of woodland along streams have boon s.cvcrcly

- 206 -

damaged, while I mile away little damage had occurred.

Kentucky. W. A. Price (May 29): Cankerworns defoliated elm trees in the
vicinity of Georgetown and Paris.

Michigan. R. Hutson (May 26): Spring cankerworms are very numerous at
Shelby, Swartz Croeek, :.Iount Clemens, lonia, Owosso, Corunna, and Lansing.

Iowa. H. E. Jaques (A.ay 25): Many orchards and a large number of elms in
home plantings, as well as in the woods, have suffered severely through-
out southeastern Iowa from the heavy infestation of cankerworms. While
both spring and fall cankerworms are involved, our examinations
indicate that the spring cankerworm is much more abundant. Mlny
neglected orchards, as well as elm trees, arc now wholly defoliated.

Missouri. L. Haseman (May 23): Spring cankerworm infestation reported a
month ago has passed the poek of development. Reports indicate that
it has booeen pretty general throughout the State but apparently central
Missouri has boon more severely infested than other parts. :Tany elm
and hackberry trees at Columbia have booeen practically denuded.of foliage.

Nebraska. M. H. Swenk (May 20): The outstanding shade tree pest in Nebraska
was the spring cankerworm. Elm, hackberry, apple, and other shade and
fruit trees, and, in one instance, grapevines were the subjects of in-
jury. Complaints of injury bcgan coming in on April 27, and have con-
tinued to date.

Kansas. J. R. 7-Trton (May 3): Spring cankerworms occurred in outbreak
nutnbcrs during the last week of March. Injury is most noticeable on
elms where the rag-cd condition of the leaves is bcconing evident.

H. B. Hun:.-crford (May 23): Spring cankerworms arc doing con-
siderable damage in sone sections of Lawrence, and some orchards in
the vicinity have been conpletoly defoliated.

H. R. Bryson ("a,, 28): Cankorworms have caused considerable
damage to elms and apple trees in various localities in eastern Kansas.
The infestations are spotted and. local.

apples at Bixby.

FOREST T31TT CATERPILLAR (Malacosoma disstria Hbn.)

Connecticut. W. E. Britton (May 21): A few larvae about half grown were
reported feedin; on linden at Now Haven. I have observed one colony
feeding upon Rosa hugonis in my garden. A few caterpillars have been
seen in other parts of Connecticut.

New England. E. P. Felt (gay 24): Forest tent caterpillars occur in small

- 207 -

ftmbern in soathtbsn fnnesticmt, &A ltv arianUe muinBerm further north
along the Connecticut River Valley, from Northampton, Mass., to Hanover,
N. H. There is a somewhat general infestation, the caterpillars being
extremely abundant in parts of New Hampshire and adjacent Vermont, with
a probability of extensive defoliation of sugar maples in unsrraycd

New York. J. V. Schaffner, Jr. (May 12): Forest tent caterpillars are
abundant in many localities in Broome and Delaware Counties. Several
woodland areas and sugar orchards are seriously infested.

TERMITES (Reticulitermes spp.)

Massachusetts. C. N. Smith (May 9): Two infestations of houses by termites
have been reported in Vineyard Haven. In one case the termites had
destroyed the entire framework of a bascminr-it window which was in
contact with tho ground. Thw adjacent studding was also d-maged to an
undetermined extent. In the other case a swarm of the winged forms
issued from the earth wall of a basement, but no dnamae to the house
has yet been discovered. Termites have not heretofore been regarded
as a serious problem on Martha's Vineyard, and inquiry reveals only
one previous infestation of a building.

Ohio. N. F. Howard (April 19): Termites swarmed unusually early from
stumps and roots under the temporary building at the laboratory at

Indiana. J. J. Davis (May 23): The number of inquiries concerning ter-
mites in the State have been numerous, probably more than last year.

Illinois. W. P. Flint ('ay 23): About the usual number of reports regard-
ing termite injury have been coming in from over the State.

ANTS (Formicidae)

Mississippi. C. Lyle (May 24): Under date of May 18, G. L. Bond, of Moss
Point, wrote as follows: "This species of ant (Solenopsis sacvissima
var,. richteri Forel.) was first reported from Mississippi early in
1935. Evidently it has been present along the eastern border of
Jackson and George Counties and in the adjoining section of Alabama
for several years. Since 1935 I have watched its spread and find that
it occurs over large areas of new territory every year." J. Mlilton
reported on May 23 that fire ants 'Uere very numerous in scver-il
localities in central Mississippi. Complaints of this species (Solonop-
sis xyloni McCook) have also been received from Jackson, in Hinds
County, and Hattiesburg, in Forrest County.

Louisiana. B. A. Ostorborger (May): Specimens of ants taken in rafters
of a residence were sent on April 21 to T. E. Snyder for determination.
They were determined as Crernmatogastor sp. near laeviuscula Mayr.

Nebraska. I.. H. Swcnk (April 29): Complaints of damage or annoyance in
houses by ants (Formicicae) were received from Dodge, Douglas, and
York Counties on April 25, April 29, and May 2, respectively. The
species concerned in the Dodge County report was the common lawn ant
(Lasius niger nconiger Emery) and the one reported from York County
was the basement ant (Lasius interjcctus Mayr). (April 25): Spc-i-,rns

Oregon. R. L. iurniss (I.ay 20): C. horculoanus modoc Wheeler began
swvarn-iin in Portland homes about the 15th of April. C. nac-ilatus
vicinus Mayr was not reported until May 17. These carpenter ants are
serious pests in the Pacific Northwest, where they often mine ex-
tensively in structural tiimbers.

E. A. Back (April 2q): An ant, Lionetopus occidenta.lis Emory,
has been present for 5 years in considerable numbers in a mausoleum
at Ashland and has been worrying the custodian because of the psy-
chological effect on the vault owners. (Dot. by ". R. Smith.)

BEETLES (Coleoptera)

New York. 7. A. Back (April 20): Ccrambceidae (Gracilia minute F.)
collected in warehouse. Deotcr.-ir-od. by W. S. 'ishor, who states that
this cerambycid is introduced in articles of commerce from Europe.

District of Columbia. E. A. Back ('Mly 20): Adults of a furniture beetle,
Hadrobrogmus carinatus Say, reared from maple furniture and a naple ox
yoke. All wood, heavily infested, had booeen protected from the weather
for years. ,as brought infested from ca-torn Connecticut in 137.
(L:ay 20-25): Tlic rhipiphorid beetle (Pclecotona flavipcs Mclsh.) was
roared in numbers from the maple ox roke heavily infsteod ith burrows
of carinatus.

Florida. E. A. Back (1March 29): a.-'--. larvae and adults of a furniture
beetle, Cator0-1a sp., taken from a winged chair, upholstered in vreie-
table fiber .and covered with cotton fabric, shipped to Tashington from
Coral Ga.bles, Fla. UpholsterinF material cut into bits by larrve
and cover defaced with exit holes. Owner had had chair during previous
residences if- Philippine a_? ".*Th.'alian Islands where Catora-na exists.

anobiid beetle, Meogastrallus librinocens Fisher, collected from paper-,
cloth-, leather-, and parchment-bound books, both old and new, in
libraries at San Antonio and St. Augustine. Infestation severe in
both of these localities. At the latter place it was recorded for
the first time. A hynmenopteron, Hoterospilus sp. (dot. by C. F. W.
Muesobock) was shaken from a book in St. Augustine and is probably a
parasite of M. librinocens, which was heavily infesting the book.

Ohio. J. N. Knull (May 27): Infestations of the powder post beetle
(Lyctus planicollis Lee.) in a hardwood floor have booeen reported from
various parts of the State during the last yc'xr.

Washington. M. H. Hatch (May 20): L. planicollis has been sent in as
injuring furniture at Bellingham and Friday Harbor during the last 2

two dozen dead adults of Tribolium madons Charp. clinging to sacks
of stored seed corn in a 1inneapolis warehouse.

PEA WEEVIL (Bruchus pisorum L.)

Oregon. D. C. Mote (:,ay): This species is present in the adult stage
in the Willamette Valley. Emergence was on April 29 and oviposition
on :,,- 15.

HOUSE CRICKET (Gryllus donesticus L.)

New Jersey. E. A. Back (May 14): Crickets established in numbers in an
oldtype house in Boonvillo throughout last winter. Apparently estab-
lished about the furnace, they crawled up the chimney to the unplastered
kitchen, where they congregated behind the warm stove in all sizes
and caused great annoyance by chirping.
