THE MORE IMPORTANT RECORDS FOR MAY, 1932
During the first week in May grasshoppers began hatching quite general-
ly in northern Utah, and were starting to hatch in South Dakota and Nebraska.
During the second week in the month (May 13) they were first observed hatch-
ing in Minnesota, North Dakota, and Iowa, and second-instar nymphs were
observed in the field in Missouri, By the 3rd week of the month they were
so abundant in southwestern Oklahama and over a wide territory in Texas as
to require remedial measures and the farmers were starting to use poisoned
bran. The situation is reported as serious in the Great Plains region and
in scattered localities southward to Texas.
The cutworm situation reported in the last number of the Insect Pest
Survey Bulletin has not materially changed. Reports of occurrence have
been received from the greater part of the country.
The Hessian fly infestation appears to be heavier and more general
throughout the winter wheat belt than it has been in several years.
The chinch bug situation has not materially changed. Despite the cold
rains in early May, these insects are still present in threatening numbers
in southern Illinois and central Missouri.
The green bug developed to destructive numbers in west-central Missouri
and northwestern Mississippi. A small outbreak was also reported in south-
The corn ear worm put in its appearance during the month in the southern
half of Mississippi; by the third week in the month there was a heavy infes-
tation of tomatoes in the Gulf Coast district of Texas.
Reports of heavy infestations of alfalfa by the pea aphid have been
received from Pennsylvania, South Carolina, Ohio, and Mississippi. The
numbers of these insects were decidedly below normal this month in Wisconsin
By the first of the month anunprecedented flight of moths of the
alfalfa webworm (Loxostege commixtalis Walk.) occurred in Colorado and
Wyoming. The moths were so numerous as to occasion the closing of stores
in some towns and materially inconvenienced motorists by their enormous
numbers. By the end qf the month new pLJ.tings of alfalfa, ere beingn
damaged and eggs were very numerous in the field.
The alfalfa weevil has been round well established in .the San Joaquin
Valley of California.
Estimates of. damage as high as 20 per'cent by the sugarcane beetle to
rice and su.arcane have been reported from Iouisiana.
In"-southern Illinois first emergence of the codling moth in cages was
on April 22 with a-heavy emergence on May 3. The peak of emrergence occurred
in central Illinois by the.20th up to.which date no emergen&e had been re-
corded in the northern part of the State.' The first adults were observed
in Delaware May 4, in southern Pennsylvania NaY,-l, and in central Penn-
sylvania May 19, in Ohio May 6, in central M.issouri May 4, and in northern
MissouriMay 9. In the Pacific Notr+t'"est the first emergence was recorded
on May 6 in Washington State and'on May 8 in southern Idaho.
.The'eastern tent caterpillar is quite generally abundant along the
Atlantic seaboard southward to Maryland.
The aphid situation in the eastern fruit belt from New York to Virginia
is not unusual. "Heowever, at Fort Valley, Ga.,' the apple aphid is appearing
in large numbers.
The oriental fruit moth started emerging in Delaware'April 5 and during
the last week in the month was emerging in large numbers. In Georgia larvae
appeared in twigs by the middle of May. This is the latest 'appearance of
first-brood larvae since the insect became established in that State. In
the East Central States it seems to be increasing in numbers, and is for the
first time generally distributed over northwestern Arkansas.
The plum curculio is reported as a week later than last year in the
north-central secti'on of Geortia. Full-grown larvae were leaving the drops
.b: the middle of the month. The insect is apparently but moderately abun-
dant over the Eas'" Central States and sbmewhat more abundant than usual in
Kentucky, Missouri, Arkansas, and Mississippi.
During the month the vegetable weevil' was discovered in Atlanta, Ga.,
the easternmost record for thei distribution of this insect. It was also re-
ported from 8 additional counties in Mississippi, which State is now entirely
infested except the northernmost tier of counties.
The seed corn maggot was .reported as doing. some damage along the
Atlantic seaboard from South Carolina to Maryland.
Onion thrips were causing very severe injury to a large variety of
truck crops in the important commercial trucking sections of eastern South
By the middle of the month the Mexican bean beetle started to appear
in the fields in the Middle Atlantic States. In North Carolina this insect
is alread~ doing considerable damage.
The bean leaf beetle appeared in destructive numbers in the South
Atlantic, East entral,and lower Mississippi Valley States.
Brood VI of the periodical cicada started to appear during the last
week in May in the District of Columbia and in near-by Maryland and Virginia,
and in Adams County, Pa. Emergence in large numbers was recorded at this
time from western South Carolina.
The larch case bearer is reported as very prevalent throughout the New
England States and in southern Pennsylvania.
The black widow spider has been found in rather large numbers in eastern
Maryland during the late winter and early spring months.
The Argentine ant was recorded as having successfully overwintered out-
side of greenhouses in Baltimore, Md. This is the northernmost record for
establishment of this pest out of doors.
Michigan R. Hutson (May 20): First-stage nymphs ..were first seen today
in Benzie Crunty. In the northern half of lower peninsula they
Minnesota A. G. Ruggles (May 21): Grasshoppers are very abundant. They
started hatching May 13 all over the State. All eggs examined
North Dakota J. A. Munro (May 23): The general hatch appears to be well
under way in a number of North Dakota counties. Newly hatched
nymphs were first observed May 13 at Fargo. In most cases the
hoppers had already moved into the fields for several rods and
destroyed a large portion of crops in Cass County on May 23.
Melanoplus bivittatus Say was the predominating species.
South Dakota H. C. Severin (May 9): Fggs of M. bivittatus began to hatch
in open fields May 4 and on the south side of buildings, banks,
etc., they began to hatch several weeks ago. (May 21): The
situation is getting serious.
Iowa C. J. Drake (May 15): Grasshoppers are beginning to hatch
in moderately large numbers.
Missouri F. D. Butcher (May 11, 12, 13): Young grasshoppers, apparently
in the first and second instars, were observed in Butler, Ripley,
and Perry Counties.
Nebraska 0. S. Bare (May 6): Grasshoppers were found hatching in
Antelope County on May 3.
Kansas H. R. Bryson (May 27): Correspondence reports indicate that
large numbers of grasshoppers have been hatching in the vicinit$es
of Alden and Bazaar.
Oklahoma C. F. Stiles (May 23): Grasshoppers are abundant in the south-
western part of the State; they are being reported in large
numbers from Love, Jefferson, and Cotton Counties, and a few
farmers have already begun poisoning.
Texas F. L. Thomas (May 23): Grasshopners are reported abundant in
many sections of the State. Reports of their occurrence in
threatening numbers come from 33 counties scattered from the
eastern to the western borders. "Thicker than in last twenty
years in Hall County."
Montana A. L. Strand (May 20): Grasshoppers are reported to be hatching
in some counties.
Wyoming A. G. Stephens (May 20): Grasshoppers are moderately abundant
in the east and southeast.
Colorado G. M. List (May 24): Grasshoppers are moderately to very
abundant. Hatching began about May 1. About at height now.
Situation probably notso bad as last year.
Idaho C. Wakeland (May 21): We are just beginning to receive re-
ports on grasshoppers. The season is later than usual, with very
much more precipitation than normal, so that hatching has been
delayed. Eggs are beginning to hatch in the Lewiston district;
and we have reports also of hatching from Cassia County. We
expect rather severe injury in a few districts of the State,
namely, Cassia and Bingham Counties.
Nevada G. G. Schweis (May 21): Grasshoppers of various species have
been reported in large numbers from three counties of western
Nevada. These hoppers have just hatched or are still in the
process. Considerable poisoned-bran bait is being used, with
Utah G. F. Knowlton (May): Eggs began to hatch in the vicinity
of Logan during the last few days in April. In early May hatch-
ing was quite general in Tooele County and northern Utah. By
the middle of the month the young hoppers were being reported
from Miller County as becoming abundant, and toward the end of
the month they were being very generally reported from the
entire northern part of the State. (Abstract, J.A.H.)
Maryland E. N. Cory (May 13): Truckers report an unusual abundance
South Carolina A. Lutken (April 28): Cutworms are general and very abundant.
Ohio T. H. Parks (May 25): Cutworms (Nephelodes emmedonia Cram.)
are very abundant. They destroyed about 3 acres of bluegrass in
a pasture in Harrison County. The weather is very dry. A
disease is killing many of the worms. Climbing cutworm injury
to apple trees was reported from Erie, Columbiana, and Mahoning
Illinois J. H. Bigger (May): Variegated cutworms (Lycophotia margari-
tosa saucia Hbn.) were reported in considerable numbers from
April 25 to May 10, in western Illinois.
Kentucky W. A. Price (April 23): The bristly cutworm (Polia reniiera
Steph.) and the clay-backed cutworm (Feltia gladiaria Morr.)
have been reported from several sections of the State, where
they have caused much damage to grass, clover, alfalfa, and
tobacco in the bed.
Michigan R. Hutson (May 21): Several species of climbing cutworms,
chiefly Rhynchagrotis alternata Grote, are numerous on fruit
trees generally in the western half of the State.
North Dlaota J. A. Munro (May 23): Several reports of cutworm injury have
been received from Dunn Prd other westrjn counties. So far the
worms have not caused any widespread injury, but the prospects
are that they will prove very destructive.
South Dakota H. C. Severin (May 20): The western army cutworm (Chorizagrotis
auxiliaris Grote) is very abundant in central and western South
Dakota and has taken entire fields of small grain. It has also
destroyed numerous gardens and fields of potatoes.
Minnesota A. G. Rugiges and assistants (May): Although cutworms are quite
generally reported, they are not unusually abundant over any
considerable part of the State, (Abstract, J.A.H.)
Iowa C. N. Ainslie (May 26): There is much complaint throuzhout
northwestern Iowa of injury to gardens by cutworms that appear
to be unusually numerous this spring.
Kansas H. B. Hungerford (May 23): Cutworms are very abundant.
Missouri A. F. Satterthwait (May 9): There seem to be many cutworms
in my garden at Webster Groves. Nearly all appear to be Feltia
L. Haseman (May 21): I have received only a few complaints on
cutworms but they are still at work, May 20.
Alabama J. -.. Robinson (May 20): Cutworms are very abundant at Ozark,
affecting several thousand acres of field crops.
Mississippi C. Lyle and assistants (May): Cutworms are not unusually
abundant over the greater part of the State this spring. Reports
of some damage to newly set tomatoes have been received from
Lamar, Alcorn, and Lee Counties. (Abstract, J.A.H.)
Colorado G. M. List (May 24): The army cutworm is moderately abundant
in a number of sections in the .Sate. In some fields it is doing
damage to alfalfa and moving out into beet fields and other
Utah G. F. Knowlton (April 26): Cutworms are seriously damaging
several hundred acres of alfalfa in Delta, Oasis, Woodrow, Oak
City, and Hinckley sections of Milford County. Approximately
one hundred acres of dry-farm wheat are reported as being
seriously damaged at Oac City. Cutworms are damaging alfalfa
in the West Mountain district of Utah County, and garden crops
in the Provo area. (April 28): Cutworms are seriously damaging
pastures in the Hopper, Roy, and West Weber areas of Weber
County. Alfalfa is damaged to a less extent in the same areas.
Texas F. L. Thomas (April 21): Prodcnia ornithoqalli -uin. is
more abundant than usual in Calhoun and Brazos Counties, possibly
because cotton is very much later than usual. (May 23):
C. auxiliaris, or a very closely related species, has been so
abundant at Lubbock and Big Spring the past three weeks that
the adults have been very annoying to persons in houses.
Nevada .G. G. Schweis (May 21): Cutworms are very abundant in Fallen
and Reno. They did heavy damage on early alfalfa.
Wyoming A. G. Stephens (May 20): Army cutworms are very abundant in
northeastern Wyoming, and there have been heavy infestations
in Crook, Campbell, and Sheridan Counties.
Montana A. L. Strand (May 20): The army cutworm did heavy damage
during April and May in parts of the State which received fall
rains in 1931. Most of this damage was in winter wheat and
was not prevalent in the southeastern tier of counties. The
predicted outbreak of the pale western cutworm (Porosagrotis
orthozonia Morr.) has occurred, although it is not so wide
spread as indicated by our forecast. Several hundred acres of
fall and spring wheat have been destroyed in .allatin County
Washington E. J. Newcomer (May 20): Cutworms (Euxoa sp., Feltia ducens
Walk., and Eriopyga sp.) are making more trouble than usual,
especially to gardens.
SALTI ARSH CATERPILLAR (E~tigmeno acraea Dnrury)
Louisiana W. E. Hinds (May 26): Salt-marsh caterpillars have been quite
abundant through the early spring but are generally rather
heavily parasitized and will probably not be destructive in the
Texas F. L. Thomas (May 23): The salt-marsh caterpillar was reported
from seven counties of northeastern Texas and from two counties
in the southern portion.
Correction: The note on Estigene acraea Drury by J. R. Watson,
page 84, Insect Pest Survey Bulletin, has been corrected.
Specimens were bred and identified as Apantesis phyllira Drury.
WHITE GHUBS (Phyllophaga sp.)
Maryland 2. N. Cory (May 17): White grubs are very abluniant.
Georgia W. H. Clarh: (April 25): County A,.ent Webb reported considerable
foliage injury to pecans at Talbotton by beetles.
0. I. Snapp (May 11): Adults were observed feeding during the
day on the roots of carrots, where they had gotten under the soil
for hiding and protection. They had ruined a plot of that vege-
table at Fort Valley.
Ohio J. S. Houser (May 26): A heavy flight of May beetles is taking
place at Wooster. The insects are much more abundant than in 1931.
Illinois J. H. Bigger (May): White grubs are very abundant in vestern
Illinois. There were hea-vy flights of adults on the evenings
of May 6 and 7.
Minnesota A. G. TRugles and assistants (May): White grifs were reported
as unusually abundant and in very large numbers from Houston and
Cottonwood. Heavy flights started in the southern part of the
State the latter part of April and in the vicinity of St. Paul
during the first week in May. (Abstract, J.A.H.)
Iowa C. N. Ainslie (May 26): These beetles are actively feeding
on the leaves of shad'trees and garden shrubs, doing serious
injury in some cases. There is as yet very little complaint
of white grub daragc.
Mississippi W. L. Gray (May 21): May beetles were causing considerable
injury to pecan trees in Natchez on April 27.
Louisiana R. L. Dozier (M:ay 2): During the wceek of April 16 to 23 a
large plot of newl'r plowed ground in NTew Orleans showed con-
siderable numbers in the larval and pupal stagcs. Newlly
issued adults were also flying in limited numbers at the time.
Kansas H. B. Hunzgerford (Mray 8): White grabs are very abuindant.
Adults are unusually abundant at Lawrence.
Pennsylvania C. A. Thomas (M1ay 20): Wircworms (Limonius aonus Say and
Hlclanotus sp.) have already caused some damage to potato seed
pieces in Bucks and Chester Counties. The cool wet weather
of the first half of May has been particularly favorable to
them. The adults were found mating in large groups on May 20.
North Carolina W. A. Thomas. (May 9): Within the past few days the larvae
of Monocrepidius vesper.t iij Fab. have been observed frequently
feeding on the under surface of ripe strawberries which were
in cont .ct with the soil at Chadbourn. Where the berries are
on proper mulch, holding them above thc soil, they seem to be
Ohio T. H. Parks (May 24): Wireworms are very abundant. They have
destroyed a field of young celery plants in muck land of
Montana A. L. Strand (May 20): Damage by Ludius sp. has been severe
in spring wheat.
California A. E. Michelbacher (May 19): Two new infestations of wire-
warms have come to my attention during the past month. The
first of these was in Oakland, where a wireworm believed to
be L. canus Lec. was attacking corn. The second infestation,
and by far the worst, is on an island in the Sacramento River
Delta near Rio Vista. On this island the wireworm has done
considerable damage the past several years. Here again it is
believed that the wireworm is the larva of L. canus. (Det.
Dr. Van DykeO A year ago it destroyed 120 acres of sugar beets.
This year Egyptian corn has been planted in the same field and
it looks now as if it is going to be damaged considerably by
A FALSE WIREWORM (Eleodes hispilabris Say)
Montana A. L. Strand (May 20): This false wireworm is more prevalent
than it has been for several years.
CEREAL AND F RAGE- CRO P I NSECTS
HESSAL~ FLY (Phytophaga destructor Say)
United States C. M. Packard (May 28): Spring Hessian fly infestation appears
to be heavier and more general throughout the winter wheat belt
than it has been in several years.
Indiana J. J. Davis (May 26): The Hessian fly seems to be moderately
abundant throughout the state so far as reports received indi-
cate. An especially heavy infestation was reported from
Williamsport, May 20. The insects submitted werE at the base
of plants and in half-grown larval stage to flaxseeds.
Illinois W. P. Flint (M-y 20): The spring brood is causing much more
damage than was at first anticipated. Many fields of wheat are
severely injured at this time before the heads have started to
form and it is certain that much of this wheat will brelak over
as soon as the heads start to fill.
Missouri F. D. Butcher (May 12 13 & 16): Wheat fields examined in
Boone, Warren, St. Charles, St. Louis, and Perry Counties were
generally infested. Almost every stool had tillers infested;
from 25 per cent to 90 per cent of straws were infested with
from 1 to 18 maggots or flaxseeds.
L. Haseman (May 20): The Hessian fly situation is alarming;
some spring-brood larvae are entering the flaxseed stage.
Kansas H. R. Bryson (May 27): A heavy infestation is developing in
fields in the vicinity of Manhattan as reported May 25. Some
fields have been plowed up. The first flaxseedsof the first
spring generation were seen May 3, The first eggs of the second
spring generation were seen in the field May 17. Infestations
have been reported from Rooks and Ellis Counties.
Oregon M. M. Reeher (May 1): First eggs of the spring brood were
found on April 1 in Washington County.
WHEAT STRAW WORM (Harmolita grandis Riley)
Kansas H. R. Bryson (May 27): Adults of the second generation were
seen in the field May 7. They are not yet abundant at Manhattan.
A heavy first generation infestation is reported at Hays.
CHINCH BUG (Blissus leucopterus Say)
Illinois W. P. Flint (May 20): Mr. Chandler reports infestation in
some areas evidently reduced by rains earlier in the season.
Considerable numbers of adults were killed by cold, beating
rains the first of May, but notenough to reduce greatly the
South Dakota H. C. Severin (May 20): We have received a few complaints
from Douglas and Charles Mix Counties regarring increasing
numbers of chinch bugs, but no serious damage is expected.
Iowa H. E. Jaques (May): Chinch bugs were reported as very abundant
in Des Moines County.
Missouri L. Haseman (May 21): Chinch bugs are very abundant in wheat
and oats in a belt across the central part of the State. Adults
taken mating May 3-10 oviposited in the laboratory and eggs
hatched May 20.
GRHEE BUG (Toxoptora graminum Rond.)
Pennsylvania J. S. Pincmkey and E. J. Udine (May 23): An infested field of
timothy at Carlisle came to our attention May 9. Characteristic
dead spots varying in diameter from a foot or two to 60 feet
occurred. About one-third of the field was killed. We had
earlier noticed the green bug in limited numbers in wheat on
this farm, but the wheat was not injured. M.ost of the damage
to timothy occurred before May 9; at that time parasites were
at work and winged aphids were developing. At this writing,
May 23, the infestation is on the wane. (Det. F. Wadley.)
Missouri L. Haseman (May 2): The county agent in Vernon County and
Extension Entomologist Jones report injury to wheat and oats.
Some fields are reported practically ruined in these counties.
Samples from Scott County show an excessively heavy percentage
of parasitism. (May 21): Only a few additional complaints on
the green bug have been received this month from west-central
Mississippi G. I. Worthington (May): A general infestation of spring
oats was observed in Bolivar County. Severe damage in local
areas in fields. Lady; beetles and larvae present in small
numbers and feeding on aphids April 18.
ARMYTWORM (Cirphis unipuncta Haw.)
Indiana J. J. Davis (May 26): Armyworm moths were common at lights
at Lafayette May 1. A student reported finding several moths
several nights previous.
Mississippi G. I. Worthington (May): The armyworm appeared in oats in
Washington Count-: at Estill May 1, seriously damaging about
100 acres of a 250-acre field. Caterpillars began to pupate
LEAF-FOOTED BUG (Leptoglossus phyllopus L.)
North Carolina W. A. Thomas (May 5): -The leaf-footed plant bug has been very
abundant during the past few weeks on wheat in the blooming stage
at Chadbourn. The heads are dotted with these insects, which
seem to be feeding on the developing grains within the heads.
COPN AR WOORM (Heliothis obsoleta Fab.)
Mississippi C. Lyle and assistants (May): The corn ear worm is appearing
in moderate numbers on early corn in the southern half of the
State. (Abstract, J.A.H.)
Texas F. L. Thomas (April 19): Approximately 75 per cent of
tomato plants are infested with young larvae in Jefferson County.
SOD WEBWOMIS (Crambus spp.)
Pennsylvania H. E. Hodgkiss (May 27):. Sod webworms are abundant in some
localities in the central and eastern part of the state, where
it is causing some trouble.
Ohio T. H. Parks (May 24): Sod webworms are no more abundant
than usual in cornfields; and careful searching has resulted
in few being found in lawns.
Tennessee J. U. Gilmore and Joe Milam (May 25): Crambids (C.
caliginosillis' Clem.) have already damaged several newly
planted tobacco fields at Clarksville, necessitating the
application of the control measure.
LESSER COT1 STALK BORER (Elasmopalpus lignosellus Zell.)
Mississippi C. Lyle (May 21): Of 29 young corn plants collected by
Inspector L. J. Goodgame near West Point on May 12, 27 had
A FLEA BE3TLE (Chaetocnema sp.)
Maryland J. A. Hyslop (May 25): Flea beetles are injuring sweet corn
in my garden at Avenel.
Ohio T. H. Parks (May 24): Flea beetles (Chaetocnema sp.) have
been injuring young corn soon after it came above ground. A
field of sweet corn near Toledo was destroyed and the beetles
are now common on corn in the Scioto Valley. They do not eat
holes in the leaf but eat along the under sides of the leaves
leaving the upper membrane intact.
Kansas H. R. Bryson (May 27): Corn flea beetles were reported
injuring corn at Winfield, May 13.
ALFALFA AND CLOVER
PEA APHID (Illinoia pisi Kalt.)
Delaware L. A. Stearns (May 19): In the past two weeks aphids have
been abundant in alfalfa and clover.
Pennsylvania H. N. Worthley (May 23): Alfalfa gencrally is heavily infested
with aphids. Attacks were reported two weeks ago in the southern
counties, and now about State College.
South Carolina A. Luthen (April 29): Pea aphids are very abundant on vetch
and English peas.
Indiana J. J. Davis (May 26): The clover aphid has been abundant in
clover and alfalfa fields. It was reported abundant and
destructive .to young alfalfa, generally in southeastern Indiana,
April 29 to May 3. Much damage was reported in some areas.
The fungus was apparently responsible for checking the impending
Ohio T. H. Parks (May 24): The pea aphis his been very serious
on some of the older stands of alfalfa and on peas at Chillicothe.
A visit to the area May 14 showed thiat .two small fields of
alfalfa had been so badly injured that they will be plowed under.
The aphids migrated from the alfalfa to the adjoining peas and
were causing great injury on them.
Wisconsin J. E. Dudley, jr. (May 4): There was an average hatch of
aphid eggs in the hibernation experiment, but a small percentage
of the aphids had sufficient vitality to live after hatching.
There is good evidence in Dane County that this condition also
occurred in the field. Stem-mother nymphs were very scarce up
to the middle of April. It is believed the available stock
present in the field is much below normal.
Mississippi C. Lyle' and assistants (May): Pea aphids attracted a great
deal of attention in various parts of the State during the
latter half of May, being particularly numerous on English peas.
Utah G. F. Knowlton (May 11): Pea aphids are moderately abundant
in alfalfa at Hopper.
Oregon L. P. Rockwood (May 1): Pea aphids are from one tenth to
one twentieth as numerous on field peas, vetch, and Austrian
thistle as they were at this time last year. During late
March ab6ut 15 per cent were parasitized by Aphidius sp. in
one field. The fungus Eatomophthora aphidis killed about 10
per cent during late April in the same field. Coccinellid
adults are but 6ne fifth to one tenth as numerous as at this
time last year, the greater part of the decrease being in
Hippodamia spp. rather than in Coccinella sp.
CLOV7R' LAF WIEVIL (Hypera punctata Fab.)
Indiana J. J. Davis (May 26): The clover leaf weevil was reported
abundant at Kokomo, May 9, but all specimens received were
attacked by the fungus which normally holds them in check.
Kansas H. B. Hungerford (May 8): The clover leaf weevil was serious
in places about Lawrence.
Oklahoma C. F. Stiles (May 24): The clover leaf weevil is doing
considerable damage to alfalfa fields in Payne County and has
also been reported. from Pottawatdmie County. It has been very
dry through this section of the State since early spring and
this insect does not seem to be seriously affected by the fungus
disease which keeps them in check.
CLOVR ROOT .CURCULIO (Sitona hispidula Fab.)
Kentucky W. A. Price (April 23): The clover root curculio has ruined
several alfalfa fields in the vicinity of Frankfort and
ALFALFA WEBWORM (Loxostege commixtalis Walk.)
Colorado G. M. List (May 24): The moths of what is known locally as
the alfalfa webworm, have been very numerous this spring. They
first made their appearance about the first of May and are still
so numerous that many reports from motorists likened it to driving
through a snow storm. The stores were reported to have closed
in one town because of the large numbers being attracted to
lights. The larvae are beginning to do considerable damage to
alfalfa. Some new plantings are badly damaged at this early
date and eggs are quite numerous on a variety of plants.
Wyoming C. L. Corkins (May 17): In fifteen years of experience in
this region I have never seen the moths of the sugar beet web-
worm so abundant and so generally distributed as they are this
year. They are simply everywhere in swarms over the eastern
section of Wyoming.
SUGA5RCATE 3ORER (Diatraca saccharalis Fab.)
Louisiana W. E. Hinds (May 26): The borer is abundant in some fields of
most advanced corn especially in south Louisiana. The first
generation began pupation about May 20. Infestation is some-
what lighter and development somewhat less advanced in Baton
Rouge area. Borer egg parasitization by Trichogramma found
first in garden corn in extreme south Louisiana at-Bayou Salle
on May 14, but natural parasitization in first generation eggs
is extremely light, as usual.
SUGARCAkTE BETLE (Euethoola rugiceps Leec.)
Louisiana W. A. Douglas (April 28): The suearcane beetle is very abun-
dant in rice fields which have not been flooded. The average
amount of injury was 21.5 per cent.
J. W. Ingram and E. K. Bynum (May I.): Injury to sugarcane
showed a marked increase during the month; it was heaviest in
the section around Franklin. In one field of plant cane 15 per
cent of the shoots .hd been killed on April 11. Amother dead-
shoot count was ma.e in this field on the 28th. It was found that
21 per cent of the remaininz shoots haid been killed.
Louisiana W. E. Hinds (May 26): Damage to corn and cane has been re-
ported as unusually severe and in many cases complaints have come
from points entirely outside of the sugarcane belt. Rice has
suffered also in some localities. Oviposition appears now to be
about completed and sadults are dying off. In northern Louisiana
the damage has been -inflicted in low moist areas especially, not
Texas F. L. Thomas (May 1): Abundant on corn at Westfield.
FRUIT IN SECTS
TARNISHED PLANT BUG (Lyg~s -ratensis L.)
Maine C. R. Phipps (May 23): This insect is reported in unusual
abundance in Aroostook County.
New York N. Y. State Coll. Agr., Weekly News Letter (May): The tar-
nished plant bug began to appear during the third week in April
and by the first week in May was reported as more numerous than
usual in the eastern half of the State (Abstract, J.A.H.)
Georgia W. H. Clarke (May 9): Considerable injury is being done to
Elberta peaches at Madison. In an adjoining orchard of Georgia
Belle practically no injury was found, although the insect was
present in large numbers on a cover crop of Austrian winter peas.
Washington E. J. Newcomer (May 20): At Yakima little additional injury
has occurred to pear since the trees bloomed, most of it having
been to the fruit buds. The first eg.gs were laid about April
1 and began hatching about April 23. The first adults from
these eggs were talken May 17.
CODLING MOTH (Carpocapsa pomonella L.)
Delaware L. A. Stearns (May 23): There was 100 per cent pupation by
May 19. The first moth was observed May 4. Emergence is
heavy at present.
Pennsylvania H. N. Worthley (May 23): Emergence began May 19 at State
College, and at Biglerville on May 11.
H. E. Hodgkiss (May 27): Codling moth emerged in traps in
Adams County May 14 and on May 18 about 18 per cent of the trap
adults had emerged. Egg-laying was reported to me on May 24,
which is the first record for the season.
South Carolina A. Lutken (April 28): Eggs are numerous in apple orchards.
Georgia C. H. Alden (May 20): This insect is moderately abundant at
Cornelia. First-brood worms are entering the fruit, the first
one May 9.
Ohio J. S. Houser (May 26): Adults are emerging in large numbers
T. H. Parks (May 24): Adults began to emerge at Ironton
SMay 6. They have emerged daily since and eggs are being laid.
The cover spray was recommnended to be applied beginning May 27.
The moths began to emerge at Columbus and 'Wooster during the
week of May 15. Only a small part of the brood has emerged up
to this time at Columbus. Moths commenced to emerge near Toledo
on May 24.
Indiana J. J. Davis (May 26): Adults first emerged at Bedford, May
6, the first eggs May 9,but because of cool weather none had
hatched by May 21, but were ready to hatch. At Lafayette the
first moths were observed May 20.
Illinois W. P. Flint (May 20): Southern Illinois--Emergence in cages
at Carbondale started on April 22, continued slowly on account
of cool weather, and began in earnest on May 3, with consider-
able numbers every day since, except for a few cool days. No
infestation in apple has yet been observed. Emergence is
about at the peak in central Illinois. Pupation is about two-
thirds completed in northern Illinois, but there has been no
emergence. The peak of the hatch of first-brood larvae will
occur in southern Illinois about May 18 to 20 and in central
Illinois about May 23 to 24.
Kentucky W. A. Price (April 23): Dr. Eddy reports the emergence of
the codling moth on April 23 at Paducah. Pupation was proceed-
ing at a fairly rapid rate on April 30.
Minnesota A. G. Ruggles (May): This insect seems to be somewhat abun-
dant in Lyon and Lac Qui Parle Counties. (Abstract, J.A.H.)
Missouri L. Haseman (May 21): Moths began to emerge about a week
earlier than in 1931, but the recent cool spell has checked
them somewhat. In southern Missouri the first moths emerged
April 23 and at some of the breeding stations practically all
the moths of the spring or first brood have now (May 20)
emerged. In central Missouri the first emergence occurred on
May 4 and we are now, May 20, nearing a peak of emergence. In
northern Mjssouri breeding stations, moths began to appear May
9 to 13 and they are now emerging in goodly numbers. Bait-pan
catches show that the caged moths and those in the orchard are
Colorado G. M. List (May 24): The codling moth came through the winter
with very little mortality and is appearing somewhat earlier
than usual in the western part of the State. At Grand Junction
Mr. L. G. Davis caught 1,604 moths in 25 "hootch" traps during
the night of May 15.
Idaho C. Wakeland (May 21): Activity is somewhat delayed this sea-
son. The first emergence in the Lewiston district occurred on
May 8 and dates in the southwestern districts were approximately
the same. Mortalityof overwintering larvae is extremely light,
and following the heavy infestation from last year severe damage
is expected this season.
Washington E. J. Newcomer (May 20): Moths began emerging in some num-
bers May 6 and owing to continued warm weather a heavy emer-
gence has occurred at Yakima since that date. During the
period May 6 to 18, inclusive, 1,579 moths were captured in
5 baits, as compared with 1,189 moths during the same period
in 1931 in the same 5 baits.
California G. S. Hensill (April 26): The codling moth is moderately
abundant at San Jose, first-brood adults appearing in suffi-
cient numbers to necessitate applications of calyx and first
Monthly News Letter, Los Angeles County Agricultural Commis-
sioner (April 28): In Los Angeles County the first emergence
of the moth was noticed about April 18.

Vermont than C-' has been the case for several years.
Massachusetts A. I. Bourne (May 24): Apple tent caterpillars were found
hatching at Amherst and Waltham on or about April 26 to 28,
which is a rather latedate. They have been comparatively
scarce throughout this immediate region. At the present time
it is very seldom found at all prevalent in commercial orchards.
Throughout the eastern and southeastern parts of the State,
however, along the roadsides, there is plenty of evidence of
continued abundance of these insects.
Connecticut W. E. Britton (May 20): This insect is more abundant than it
was last year. Is on the increase.
New York N. Y. State Coll. Agr., Weekly News Letter (May): The eastern
tent caterpillar is very abundant on roadside trees and in un-
surayed orchards. (Abstract, J.A.H.)

species of case bearers were observed during the last week in
April, and by early May they were becoming conspicuous. By the
end of the month they were causing injury in scattered orchards.
Pennsylvania H. N. Worthley (May 23): The pistol case bearer (C. malivorella
Riley) is abundant in some orchards in southern Franklin County.
FRUIT TREE LEAF ROLLER (Cacoecia argyroshila Walk.)
New York N. Y. State Coll. Agr., Weekly News Letter (May): Leaf rollers
began hatching during the first week in May in the lower Hudson
River Valley. By the middle of the month they were hatching in
central New York rnd during the third week in the month they
were reported from the lake fruit belt. This insect seems to
be more abundant than usual this year. (Abstract, J.A.H.)
Ohio E. W. Mendenhall (May 18): I find some apple leaf rollers on
apple trees in home orchards at New Carlisle.
California G. S. Hensill (May 13): Adults of the fruit tree leaf roller
are appearing in large numbers in codling moth bait traps in

New York N. Y. State Coll. Agr., 'Weekly News Letter (May): The bud-
moth was reported as very active in the lo''er Hudson River Valley
during the first week in the month; and they were starting to
appear in the lake fruit belt at about the same time. By the
middle of the month they were causinig considerably more injury
than last year in the Hudson River Valley. .(Abstract, J.A.H.)
Maine C. R. Phipps (May'23): Fruit aphids are very abundant in
.southern Maine. Reported in considerable abundance on apple.
Wisconsin E. L. Chambers (May 25): Aphids are very abundant all over

arind Washington Counties. Most serious outbreak since 1922.
APPLE GRAIN APHID (Rhopalosiphum prunifoliae Fitch)
New York N. Y. State Coll. Agr., .Weekly News Letter (May): This
species was by far the most plentiful in both the eastern and
western sections during the early part of the month. Late in
.the month the second-generation winged forms were observed, by
the middle of the month in the Hudson River Valley, and during
the third week in the month in the western half of the State.
Virginia L. R. Cagle (May 25): Grain aphids are scarce at Roanoke.
APPLE APHID (Aphis pomi DeG.)
.Massachusetts '" A. I. Bourne (May 24): Green apple aphids are reported in
considerable abundance in orchards throughout the State. There
appears to be a fairly heavy infestation, generally.
Georgia 0. I. Snapp (May 23): The infestation on apple trees at
Fort Valley is one of the heaviest I have observed. Practically
all of the leaves o0 young trees have rolled as a result of the
ROSY APPLE APHID (Anuraphis roseus Baker)
New York N. Y. State Coll. Agr., Weekly News Letter (May): During
the first week in May heavy infestations were observed in
Yates, Ontario, Erie, Niagara, and other lake counties.
During that week in the Hudson River Valley they were present
but doing no commercial damage. A rainy period early in the
month materially checked these insects throughout the State.
By t'he middle of the month they were again on the increase,
and by the third week in the month were threatening to do some
damage in the western part of the State. (Abstract, J.A.H.)
Pennsylvania J. R. Stear (May 24): Rosy aphids are very abundant at
Ligonier this spring, due, I think, to the rather dry season.
Delaware L. A. Stearns (May 23): Infestation throughout the State is
light to date and very spotty.
Missouri L. Hasemau (May 21): Rosy apple aphids are causing some
damage in southwestern Missouri. They have not been observed
Oregon D. C. Mote (April 21): Rosy aphids are very abundant in the
Willamette Valley, curling the leaves.
WOOLLY APPLE APHID (Eriosoma lanigerum Hausm.)
Washington E. J. Newcomer (May 20): In spite of a minimum temperature
of -3 F. during the winter, many woolly aphids survived on
the trees and are getting an early start. However, the heavy
infestation last fall resulted in the production of large
numbers .of predators, and these have come through the winter
well and are very noticeable at the present time. Lacewing
flies are especially numerous.
APPLE REDBUGS (Lygaeidae)
New Yo'k N. Y. State Coll. Agr., Weekly News Letter (May): Lygidea
mendax Reut. ahd.Heterocordylus nalinus Reut. were observed
hatching during the second week in May in the lower Hudson
River Valley. By the third week ih'the month they.were appear-
ing in the lake region. This pest appeats to be more plenti-
ful this year than last in the ludson River Valley.
Pennsylvania H. E. Hodgkiss (May 27): Apple redbugs are of local impor-
tance following a severe outbreak of last year. They have
almost entirely disappeared from orchards in the south-central
section of Pennsylvania.
Connecticut P. G4rman (May 20-24): The white apple leafhopper (Typhlo-
cyba pomaria McAtee, is generally slow in appearing in many
orchards in New Haven and Hartford Counties. The peak of
energence had not yet been reached on May 20. Reported as
abundant in some orchards in Windham County,
New York N. Y. State Coll. Agr., Weekly News Letter (May): By the
middle of the month, apple leafhoppers (T.'pomaria) began to
appear in the orchards in the Hudson River Valley, and by the
end of the month they were quite abundant in that section.

13 they were coming out inrnumbers and continued to do so
during the remainder of the month. (Abstract, J.A.H.)
Kansas ,H. R. Bryson (May 27): This insect is very abundant in
apple orchards in Doniphan County, and is causing considerable
injury to the young apples and fruit spurs.
FLAT-HEADED APPLE TREE BORER (Chrysobothris femorata 01iv.)
Pennsylvania J. N. Knull (May 15):- The first' adults were observed in
Fulton County on May'15. Many maple'trees throughout the
State which suffered with sun scald:during the summer of 1930
were infested with this borer in the areas injured by the sun.
Georgia' 0. I. Snapp (May 13): An unusually-.heavy infestation has
developed in devitalized portions 'of peach trees interplanted
in a pecan orchard at Albany. The adults from these peach
trees are causing serious damage to pecan- twigs just below
** the new growth.
Tennessee H. G. Butler (May 9): Aduts were obse'ved to be rather
common' ir&peach orchards in the vicinity of Harriman last
spring (3.931). The first to be observed d"is sring (1932)
was taken on May 6.
Mississippi D. W. Grimes (May): The flat-headed apple tree borer is
moderately. bundant on :pecan at* Durftaf.
APPLE FLEA 7WE VIL (Orchestes pal'licornis Say)
Ohio J. S. Houser (May 26);: Practically all overwintering beetles
have died around Jackson and Chillicothe. This insect for the
most part is inthe-mature larval and pupal condition in the
leaves. Young trees growing;,ner, old orchards severely damaged.
SHOT-HOLE BORER (Scolytus rugulosus Ratz.)
Wisconsin E. L. Chrabers (May 25): Shot-hole borers are becoming very
abuwndant in many neglected farm orchards throughout the
southern part of the State.
E 'UR ''E EAT RED MITE (Paratetranychus pilosus C. & F.)
Massachusetts A,. I. Bourne (May 24): The European red mite was found to
be hatching near Amherst on the 9th of May. On the warm days
immediately following that date they appeared in large numbers.
New York N. T. State Coll. Agr., Weekly Ny7s Letter (May): The
European red nite was reported*a quite generally abundant
over the eastern and central part of the State. (Abstract,J.A.H,)
PEACH BORER (Aegeria exitiosa Say)
Tennessee H. G. Butler (May 9): LarvaeDwere observed to have left
the trees and constructed cocoons in the soil on Mpy 3 at
Harriman. (May 25): Larvae collected in cocoons on May 10
were in the pupal stage May 25. Moth emergence has not yet
Virginia H. G. Walker (May 26): The peach borer is very abundant.
PEACH TWIG BORER (Anarsia lineatella Zell.)
Kentucky W. A. Price (April 23): Injured twigs were received from
Clay on April 26. Reports from Festern Kentucky indicate that
this injury is quite common.
Missouri L. Haseman (May 2): There is an unusually heavy twig injury
due to the common peach twig borer in Boone, Cole, and other
central Missouri peach orchards.
Utah G. F. Knowlton (May 11): Peach twig borers are damaging to
many orchards in Utah County.
Washington E. J. Newcomer (May 20): More inquiries have come in regard-
ing this insect than ever before around Yakima.
R. L. Webster (April 27): Peach trees have been severely
injured at Clarkston.
ORIENTAL FRUIT MOTH (Grapholitha molesta Busck)*
Delaware L. A. Stearns (May 23): One hundred per cent pupation by
May 11; first larvae, May 11; first moths, April 5; heavy
emergence about April 25 and May 5.
Virginia L. R. Cagle (May 25): The oriental fruit moth is moderately
abundant at Roanoke.- somewhat more abundant than at any time
South Carolina A. Lutken (April 28): The oriental fruit moth is moderately
abundant in Pickens and Oconee Counties: there is considerable
Georgia C. H. Alden (May 20): The oriental fruit moth is moderately
abundant at lornelia. First brood moderately abundant in twigs.
A few found in peaches.
0. I. Snapp (May 17): The first twig injury of the season
at Fort-Salley was observed today. The larvae were 3 or 4
days old. This is the latest appearance of first-brood
larvae at this point since the insect became established in
Georgia. The first twig injury last year was obsrrved on
April 22. The dates of first twig injury of the other years
are: April 29, 1930; April 4, 1929; April 25, 1928; April
1, 1927; April 20, 1926; April 10, 1925. At least one brood
less than usual is anticipated this year. The insect is of
only secondary importance in this part of the Georgia peach
W. H. Clarke (April 29): The first twig injury of the season
was found today (April 29) in an abandoned orchard at The Rock,
Upson County. This orchard has a number of late peaches and
apple trees which permitted a late brood to developelast year.
Ohio T. H. Parks (May 24): The oriental fruit moth is very
abundant. Injury to peach terminals is very prominent in
Lawrence County. Many of the larvae were full grown and had
left the twigs on May 20.
Illinois W. P. Flint (May 20):iThe oriental fruit moth is much more
abundant in southern Illinois than was the case last year.
Apparently the first-brood larvae are nearly all mature. A
large number of larvae were observed in peach fruit at Cen-
tralia on May 19. This is unusual for this time of the year.
Tennessee H. G. Butler (May 25): A heavier initial infestation is
present than in the previous seasons. It is regarded as sig-
nificant that the twig collections were for the most part
obtained from orchards in which clean-up measures were not
employed last fall, and opportunity was; afforded for late
fruit-infesting larvae to complete their development and
hibernate in the orchards. (May 28): Young larvae were
found in peach twigs today at Harriman. This is the earliest
date on which I have found them in this vicinity.
Arkansas D. Isely (May 21): Larvae are moderately abundant in a
number of orchards in Benton and Washington Counties, occurring
practically wherever there are mixed plantings of peaches and
apples. This marks the first general infestation in north-
*Correction: The notre under oriental fruit moth, by C. F.
Fluke, on page 94 of the May 1 issue of the Insect Pest Survey
Bulletin, referred to the codling moth (Carpocapsa pomonella L.)
PLUM CURCULIO (Conotrachelas nenuphar Host.)
Delaware L. A, Stearns (May 23): The peak of emergence from hiberna-
tion occurred from May 4 to 11. The insect was reported as
injuring pear at Bridgeville.
New York N. Y. State Coll. of Agr., Weekly News Letter (May): The
first aiult was observed in the field on May 11 in the Hudson
River V4lley. By the middle of the month they were emerGing
in numbers, though not unusually abundant. (Abstract, J.A.H.)
South Carolina W. C. Nettles (April 28): During the week prior to April
11 one curculio was jarred from the trees. On April 11 trees
were jarred and two captured from peach and plum trees.
Georgia 0. I. Snapp (May 14): Full-grown larvae began to leave peach
drops at Fort Valley today. This is a week later than last
year and seventeen days later than in 1930, when only one
brood occurred. The present stage of development of peaches
is about a month later than normal.
W. H. Clark (April 29): In a mixed peach, anple, and plum
orchard at The Rock, Upson Co., a heavy infestation was
observed. Practically all peaches showed feeding and egg
punctures, and in some fruits half-grown larvae were found.
This orchard has received no attention this season.
Illinois W. P. Flint (May 20): Mr. Chandler reports plum curcutlio
infestation very li.ght on apple this year. Owing to the
shortage of the peach crop the insect is more abundant on
the few peaches remaining on the trees. The injury has been
done chiefly since the warm days starting May 3.
Kentucky 0. 0. Eddy (May): Evidence this year shows that the curculio
is much more abundant than during 1931.
Tennessee H. G. Butler (May 25): Eggs were found in stock tars at
the insectary at Harriman.on May 5. The first nature larvae
left fallen fruit May 18. This is.four days earlier than
larvae were found in 1931.
Mise~ati L. Haseman (May 20): Very abundant and active at Columbia,
causing plums to drop and'larvae are feeding. Adults appeared
early in May puncturing plum, cherry, and apple.
Arkansas Win. G. Amstein (May 2): Heavy attack on neaches in a small
orchard at Hazen.
C. L. Rodgus (May 7): I don't understand why we should
have as many as/o at Nashville when there were practically
no wormy peaches last year at harvest time.
Mississippi C. Lyle and assistants (May): The plum curculio is very
abundant over the greater rart of the State, infesting peaches,
cultivated plums, and wild plums. In Monroe County practically
all neaches are damaged. (Abstract, J.A.H.)
Texas F. L. Thomas (May 3): Infested plums were sent in by a cor-
respondent from 7Tharton County.
PENTATOMID BUGS (Pentatomidae)
Pcnnsylvania H. 3, HodgkHis (M7y 27)': A species of pcntatomid was dis-
covered causing extensive injury on peaches; the type of work
being very similar to that of Acrosternum hilaris Say.
Illinois W. P. Flint (May 20): Mr. Chandler reports peach catfacing
much more severe than last year, ranging from 8 to 30 per cent
in southern Illinois orchards. It is probable that pentato-
mids did much of the injury this year.
HOODED PLANT BUG (Euthochtha galeator Fab.)
Georgia 7. H. Clarke (May 4): Injury consisted of feeding on the
tender twiigs,causing them to wilt and die,at Fort Valley.
Adjoining peach, plum, Pnd quince seedlings were not attacked.
PEAR PSYLLA (Psyllia pyricola Foerst.)
New York N. Y. State Coll. Agr., feekly Nevw Letter (May): During the
first week in May egg-laying increased ranidly in the lover
Iudson River Valley. By the second week in the month egg-lay-
ing started in the western -art of the State with nymphs be-
coming numerous in the Hudron River Valley. As a whole the in-
festation a-ocars to be comrarativoly light. (Abstract, J.A.H.)
Illinois 7. P. Flint (May 20): MIr. Chandler re-orts the -ear pyslla
infestation light in all sections of southern Illinois.
Michigan R. Hutson (M:ay 25): Second-stage nymnhs observed in Berrien
County on M.Iy 25.
PEIAR TI7RIPS (Taeniothrius inconsequcns Uzel)
New York N. Y. State Coil. Agr., a'eckly NI-s Letter (May): Pear thrips
are quite numerous and occasioning some damage in the lo.wr
Hudson River V~lley. (Abstract, J.A.H.)
PEAR MIDGE (Contarinia pyrivora Riley)
New York N. Y. State Coll. Agr., Weekly News Letter (May): Pear
midges were observed for the first time in the lower Hudson
River Valley during the last few days of April and in western
New York during the first week in May. By the end of the
month injury was becoming apparent in the Hudson River
Valley section. (Abstract, J.A.H.)
CALIFORPIA ROOT BORER (Prionus californicus Mo tz e.)
Utah G. F. Knowlton (April 28): The California nrionus is seri-
ously damaging cherry trees on several farms in Davis County.
A DASCILLID (Dascillus -lumbeus Horn)
California F. H. Wymore (Anril 26): This beetle was found to attack
the buds and young leaves of small, recently planted cherry
trees at Fairfield. As many as 10 beetles were removed from
some of the small trees. Two-year-old cherry trees growing
just across a small creek were not attacked.
PZACH BA3K BE-TL2 (Phthorophloeus liminaris Harr.)
Pennsylvania J. 1. Knull and G. S. Perry (May 3): Many wild black cherry
trees in the vicinity of Burning Well, Elk County, are heavily
infested. The infestation occurred in the fall of 1931 and is
due to an unhealthy condition of the trees. Increment borings
showed slow grov th for the last few years.
BLACK CHERRY APHID (Myzas cerasi Fab.)
California E. 0. Z sis, (May 20): Black cherry aphids are very abund-
ant and destructive in the San Francisco Bay district.
COMMON RED SPIDER (Totranychus tclarius L.)
Idaho C. 7akoland (May 21): May 11 no red soiders could be found
emergin. around the bases of cherry trees in the Lewiston dis-
trict but on May 19 they were found abundantly on the lower
leaves and many eggs had then been deposited. The red spider
has caused extremely severe damage to cherries in this dis-
trict during the past two seasons and the outlook this year
is for a re-etition of damage in orchards where control is
not obtained early.
RASPBERRY FRUIT O "R (Byturus unicolor Say)
New York N. Y. State Coll. Agr., Weekly News Letter (May): The rasp-
berry fruit worn has been causing more injury than in several
years by skeletonizing the leaves and blasting the flowers
in Orange and Ulster Counties in southern New York. (Abstract,
Washington J. Wilcox and W. W. Baker (May 12): The first record we
have of the adults feeding on evergreen blackberry was ob-
tained today. The flower -buds are not out yet but several
specimens were seen feeding in the opening leaf buds in Fuyal-
lipo. (May 12): Eggs found on thimbleberry today; the first
eggs observed this season in Puyallup Valley. (May 16): Could
find no eggs in either of two fields of loganberry examined
in Auburn. (May 18): Eggs were found in fair numbers today
in Puyallup on King ras-berry. (May 20): Feeding by the
adult was common on the buds of native'blackcap(Rubus leuco-
dermis) in a patch examined today in Puyallup. Only one egg
was located in examining buds on several bushes though the
fruits of the first blossoms are well develooed.
BLACK GOOS-SERRY 30RER (Xylocrius agassizi Lee.)
Washington 7. 7':. Baker (May 15): The first snecimen of this genus I
have seen from this State was beaten from a native snecies of
gooseberry today in Mineral.
A CURCULIONID (Panscoous toroidus Lec.)
Washington Umn. 7. Baker (May 16): Evidence of damrn.e to the under-
ground -portion of the new shoots wrs obtained today in Alder-
ton. The ndult gouges out nortions of the cane from 1 to
4 inches below ground and in many cases weakens the c-no so
that it brcaks off at about the ground level.
RASPDERRY SATFLY (Monophadnoides rubi Harr.)
Ohio E. J. Mcndenh.ll (May 18): The rasnberr:y sawfly is quite
noticeable in the ras-berry plantations in Fairfield County.
Iowa H. 2. Jaques (May 27): This sawfly is very abundant in our
region this year. The top leaves of many of the plants in
almost evcry raspberry patchaie badly riddled. It is the
first that it has come to our attention in our region.

AN APHID (Aphiidac)
7ashington *'.:. 3akcr (May 18): On May 7 scveral "ing raspberry fruit
spurs were :observed in Puyallup which had been injured and the
growth retarded by this aphid, burt at that time no nymphs were
present though many cast' skins were in evidence. On May 18
nynphs' ere'abundant on many fruit s-urs throughout the field.
No winged forms were collected.
J. Wilcox and 7. W7. 3krer (May 12): In five previous ye:rs
in Puyallun no aphids ;were seen on Evergreen blackberry at
this time of the year. Today many of the new shoots vere
heavily infested. Two growers reported anhids as abundant on
their canes and aphids have been rather serious rests in past
ROSE SCALI (Aulac:asnis rosae 3ouche)
Maryland 2. N. Cory .(May 13): This insect is quite -revalent in most
of the rasoberry Dlantings in Washington County.
Ohio E. '. Meendenhll (Mry 18): The rose scale is quite bad on
raspberry and blackberry canes in Fairfield County.

appear to be suffering most from the attack. The infestation
is quite general over the entire section. As many as 35 thrips
have been counted in the field of a microscope, five-eighths
inches on the under side of a cucumber leaf. An average of
14 thrins was found on each of 100 similar sized areas on 100
cucumber leaves. Since May 1 the insects have spread to ad-
jacent cucumber, 'bean, -otato, and onion plantings. The fol-
lowing native plants in the vicinity of truck plantings were
found to be infested: Goldenrod, milkweed, smartweed, pig-
weed, and Johnson grass. (May 13): Thrios were found to be
moderately abundant on small'plantings of cucumbers and melons
in the central portion of the State. (May 14): They were

M.- D. Leonard
Insular Experiment Station, Rio Piedras, Puerto Rico.
The scarabaeid beetle yscinetus barbatus Fab. was abundant during
early May this year and last rear, at Isabela, (G.N. Wolcott. )
The fkt adult Lachnosterna vandinei 'Syth was observed this year
on March 10, the second on April 10, and they were abundant during late
April. Last -ear the first adult was observed on April 19 and they were
abundant last year in April, at Isabela. (G.N. Wolcott.)
The first adult Lachnosterna citri Smyth was observed this year on
April 15 and they were abundant on April 17; last year the first adult was
observed on April 17 and they were abundant on the 18th and 19th, at
Isabela. (G.N. Wolcott.)
The period of greatest abundance of the large weevil (vaquita)
Diaprepes abbreviatus L. as adult is also during the latter part of April,
following a period of several months when rarely can an individual be found.
SDuring the rest of the year the beetles are present in reasonable numbers,
with minor variations, but during the first quarter.of the year adults are
very scarce. Their appearance in the latter part of April coincides with
the new flush of growth on citrus and other trees, caused by spring rains,
which have been normal this year. Even for this irrigation district, how-
ever, one can hardly consider the almost 10 inches of rainfall that have
fallen in the last 48 hou-rs- as being quite normal.
