INSECT PEST SURVEY BULLETIN


Vol. 11 September 1, 1931 No. 7


OUTSTANDING E.TTOMOLOGICAL FATTJURES INT TH U.ITD STATES FOR 2GU 1931.

The serious outbreak of gr shopperss in the Great Plains region which developed during July continu through the greater part of August, with lesser outbreaks over practically the entire country.

Rod spiders of several species attacking a groat variety of plants,
including forest and shade trees, truck crops, flowers, fruits, and shrubs, were reported from scattered localities across the northern part of the United States, from 1Maine through South Dakota -and Idaho to Utah and Oregon.

A few specimens of the European corn borer ;::0 discovered for the first time in the State of Wisconsin, having been found in a field in Mosel township, Sheboygan County, on Lake Michigan.

The Japanese beetle has been collected at Cleveland and Columbus, Ohio, these being the first records for this State.

The corn ear worm continued tc be reported as unusually a'oundant from practically the entire corn-growing area of the United States.

A very unusual outbre k of chinch bugs occurred at Windsor, Berkshire County, Mass. The outbreak was not CXtensive but the insects occurred in enormous numbers over a small area of corn and millet, The chinch bug situation as a whole in the Middle West has not changed materialy since last month, although the insect has been reported this month from the lower tier of counties in Michigan and the southeastern corner of Minnecota.

The garden webworm was reported as seriously damaging alfalfa in scattered localities from Indians to North Dakota and Iowa.

Sod webworms c: unusually destructive to lavwns, golf greens, and pastures from Ohio we;estwrd to 1orth Dakota and south hard to Missouri anTennessee.

The codling moth situation has not changed materially since July. This insect continues to be seriously prevalent from New York southward to Georgia and in scattered localities from the East Central States, westward to the Pacific Northwest.

The oriental fruit moth has been found at Springdale, Ark., this year. This is the first record from northwestern Arkansas.

The grape leafhopper was very seriously abundant throughout the
northern part of the San Joaquin Valley in California where it is said that they will materially reduce the marketable tonnage of grapes.

The Pacific red spider was extremely numerous late in July on grapes, deciduous fruits, and ornamentals in central California. .Early in August this- insect was practically eliminated by the predacious thrips Scolothrips semaculatus Perg.

An unusual da.nage to citrus is reported from Los Arngeles, Calif.
The false chinch bug is serioclyr d :aging young trees in groves adjoining wheat. and weed fields.

The second finding of Cardints whitefly (Alerod.icus Metaleurodicus) cardini Back) in the United States is reported in this number of the Insect Pest Survey Bulletin. Specimens were collected on guava in moderate abundance at West Palm Beach, Fla. The first finding was in February, 1921, when specimens were collected by W.. B. Wood, of the Plant Quarantine and Control Administration, in the Plant Introduction Gardens at Miami.

Blister beetles were quite prevalent throughout the entire .Mississippi Valley from Indiana, Minnesota, andd North Dakota southward to Louisiana and Mississippi.

The plant bug Engytatus geniculatus Reut. was recorded for the first time as a pest of tomatoes in Orar4nge County, Calif. This insect is said
to be injurious to tomatoes in the Hawaiian Islands.

Late in July the Mexican bean beetle was found at Brattleboro, this
being the first record for the State of Vermont. This insect is extremely prevalent and destructive throughout the northern part of its range, particularly north of the drought area of 1930.

Two coreid bugs, Alydus eurinus Say and A. pilosulus H. S., were found seriously injuring heans in Georgia.

During the last week of August the sugar-beet webworm developed in rather large numbers in parts of North Dakota, South Dakota, and Utah,

Many fields of peppers in southern California have been damaged from 25 to 40 per cent by the pepper weevil.

The weevil Trichalophus didymus Lec. has been found infesting straviwberry crowns on the mainland at Tacoma, Wash. Heretofore, this insect has only been known from Wibley Island, Wasington.

For the first time in many years the potato tuber moth was injurious to tobacco in Dane, Rock, and Jefferson Counties, Wisconsin.

The bagworm was quite generally roported from Pennsylvania westward to Indiana and Kansas, and southward to Mississippi.







-421

The saddled prominent, which ha.s been in outbreak numbers in New England
during the past few years, seems to have reached its peak during 1930 and this year is appearing in considerably reduced numbers.

The fall webworm is very abundant throug-hout New England and the Middle Atlantic States.

The elm leaf beetle was found early this spring in the Yosemite National Park in California. This is the first record of this insect in the Park.

The gladiolus thrips (Taenicthrips gladioli H. & S.) is very seriously
injuring gladiolus in the New L0 .and, Middle Atlantic,and East Central States.


OUTSTAjDING ETOMOLOGICAL FEATURES IN CAJADA FOR AUGUST, 1931

Outbreaks or incipient outbreaks of grasshoppers, notably the lesser
migratory, clear-winged, and two-striped grasshoppers, are occurring in many districts over a wide territory in the Prhirie Provinces, and conditions are threatening for 1932. In eastern Ontario and southern Quebec, the red-legged grasshopper is more abundant than for many years past, and is increasing. Various degrees of damage to field crops are being reported from sections of all the above-mentioned provinces.

An unusual outbreak of the green clover worm has developed throughout
most of the bean-growing areas of southwestern Ontario, resulting in crop defoliation and a reduction in the yield. Although generally present, this
species rarely reaches injurious proportions in Ontario.

A marked incre,.se in the abundance and destructiveness of the Colorado potato beetle has now been reported over a considerable part of the range of this insect in Canada, including the Maritime Provinces, Quebec, Ontario, and the Prairie Provinces.

Sod webworms which occurred in outbreak form throughout southwestern
Ontario, damaging or destroying lawns, golf greens, etc., have been determined as Crambus mutabilis Clem. and C. trisectus Walk. A third species, C. dorsipunctellus Kft., was recorded as injurious to lawns at Winnipeg, Man.

In Manitoba, Saskatchewan, and Alberta, blister beetles, Lytta nuttalli
Say, are attacking caragana hedges and gardcn legumes, such as beans and peas. The increase in abundance of these insects appears to be associated with the widespread grasshopper outbreak developing in the Prairie Provinces.

In certain areas of southern Alberta the diamnond-back moth is even more abundant than last year, when it caused serious damage to cruciferous crops.

The wheat stem sawfly appears to be more generally abundant than usual throughout its range in Saskatchewan.







-422

Chinch bugs are reported to be causing material damage to lawns in the city of Halifax, Nova Scotia. This -pears to be the first record of its occurrence in injurious abundance in Nova Scotia.

A particularly severe outbreak of the pea aphid occurred this season in oea-growing sections of southwestern Ontario. Local outbreaks were also reported in Fredericton, New Brunswick, and in the Chilliwaclt region of the
Lower Fraser Valley, British Columbia.

There has been a reduction in the infestation of the connon red spider in Saskatchewan and Alberta as compared with 1930, but material damage has been done to a variety of plants including- roses, raspberries, low shrubs, and herbaceous plants.

The gladiolus thrips, Taeniothrios gladioli .oulton, has caused serious damage to gladioli in many parts of Ontario and southern Quebec.

The painted lady butterfly and its larvae are conspicuously common in the" Maritime Provinces and Quebec, and are extremely abundant in the Prairie Provinces. As the attacks of the larvae are largely confined to thistle this species may be classed as beneficial.

The beet webworm is again very abundant in Manitoba and Saskatchewan, attacking weeds principally but also crasing damage to flax.

The lesser clover leaf weevil is widely prevalent in the Maritime Provinces, and in many localities an average of 15 per cent of the cover heads are
infested.

The squash bug has developed in unusually destructive numbers in sections
of southern Ontario.

in unusually large second brood of codling moth larvae is anticipated in the Niagara district Ontario. The infestation of the oriental fruit moth is reported as very light, s'o far. The apple and thorn skeletonizer is conspicuous in neglected apple orchards.

Insect injury to all varieties of fruit in the Okanagan Valley, British Columbia, is reported as remarkably scarce.

The fall webworm continues to increase in abundance in many parts of
eastern Canada, and is a noticeable pest on various fruit and shade trees and shrubs.

The infestation of spruce and balsam by the black-headed tip moth in Cape Breton Island, Nova Scotia, has been markedly reduced, and this year's feeding by the insect is unimportant.

The European pine shoot moth is prevalent on certain species of pines in Welland County, Ontario, particularly around summer homes along the north shore of Lake Erie.










The aspen poplar leaf beetle is widespread and appears to be increasing
in southern sections of Manitoba.

The walnut caterpillar is again in outbreak form in southwestern Ontario, defoliating: many trees.

Reports indicate that mosquitoes, black flies, and certain other biting
flies'have been unusually scarce in many parts of eastern Canada, and probably also in* the Prairie Provinces.









GE N. RAL F E.ED.E R S,

GRASSHOPPERS (Xcridida.e)

South Carolina A. Lutken (August 25): Grasshoppers in general are more
abundant than usual.

Ohio T.-H. Parks (August 24): More than the usual n umbers of
grasslhoppers are present in most western Ohio counties. Damage
has not been very serious owing to plenty of rains to favor
growth. Poisoning work has been carried out in several counties.

Indiana J. J. Davis (August 22): Grasshoppers destroyed alfalfa on a
3k-acre field at Indianapolis August 1. They also damaged onions.
During July grasshoppers were conspicuously abundant and destructive in Clinton County.

W. B. Noble (July): The Carolina locust, Dissosteira carolina L, was unusually abundant in central Indiana. It was observed
flying about lights at night.

Illinois J. H. Bigger (August 18): Grasshoppers are damaging soybeans,
alfalfa, and corn. I have investigated severe outbreaks in
about 90 acres of soybeans and 20 acres of alfalfa in Morgan and Greene Counties. Damage to corn was seen in Morgan, Greene, and
Christian Counties. Only a small part of the damage in these
areas was seen.

Michigan R. Hutson (August 24): Grasshoppers are very abundant in
grains in the upper peninsula. There are no blister beetles and
few hairsnakes.

Wisconsin E. L. Chambers (August 24): Local outbreaks of grasshoppers
have been damaging crops in many sections of the State, doing
serious injury to tobacco, corn, and small grains.

Minnesota A. G. Ruggles and assistants (August): Grasshoppers were
reported during August as still doing serious damage at many
points throughout Minnesota. The species involved, in the order
of their importance, were Melanoplus bivittatus1Say, Camnula
pellucida Scudd., M. atlanis Riley, M. femur-rubrum DeG., and
Dissosteira carolina L. (Abstract, J.A.H.

Kentucky Mary Didlake (August 24): Grasshoppers are very abundant on
tobacco and tomatoes in Fayette and other counties.

North Dakota JA.Munro (August 22): Grasshoppers have been the pest of
greatest abundance in North Dakota this season. Indications are
that there will be another serious outbreak next year.

South Dakota H. C. Severing (August 20): Grasshoppers are very abundant.
The outbreak has become more extensive and much of the State is
affected.






-425

Nebraska M. H. Swenk (July 15 to August 1): The grasshopper outbreak
continued tb develop in extent," and somewhat in severity, during
the last half of. July. The 31 izifestgd counties reported on July 15 have now increased to 65, though in many of these the
damage iq neither widespread nor serious. The infestation has
been heavy and general, and the crop loss serious, in Arthur,
Boyd; Buffalo, Dawson, Keith, Keya Paha, Knox, and Perkins
Counties. Cedar, Dixon, and Holt Counties have been largely
heavily infested. Parts of Brown, Chase, Cherry, Custer, Greeley,
Lincoln, Rock, and Sheridan Counties have been heavily infested. Iowa C. J. Drake (Aujast.3): Grasshoppers are extremely numerous

over a large section of Iowva, particularly in the western half
of the State. Many fields of new alfalfa have been totally
destroyed by the hoppers, and considerable damage is being done 7
in old alfalfa fields. To illustrate, in Monona County an
80-acre field of alfalfa was totally destroyed by the hoppers
after the first crop was h-:rvested. I visited this field about
ten days ago and it was impossible to find any new growth in the field. The differential locust, ,M. differentialis Uhler,
is the predominating species. The two-striped locust, elanoplt s
bivittatus Say, is almost as abundant as the foregoing species.
The red-legged locust,M. femur-rubrum DeG., is also very abundant.
The lesser migratory locust, M. mexicanus Sauss.,is almost as
abundant as the red-legged locust. In some fields in the western
portion of the State the hoppers run around 20 to 40 per hill of corn. These fields are not very numerous. Most damage is being
done in alfalfa fields and around the margins. of cornfields. The
State of Iowa has just purchased four carloads, Of commercially
prepared poisoned bran mash to take care of heavily infested
waste areas along the Missouri River and other sections of western Iowa.

Missouri L. Haseman (August 25): During August the three common species
of grasshoppers h'we been very destructive.

Kansas H. R. Bryson (August 22): The grasshopper problem is a serious
one over the entire State. Although there are a large number of all species present the greater part of the damage is being done by Yelano-plus differentialis and M. bivittatus. M. atlanis and
M. f'emur-rub3n-n are also numerous and will no doubt cause considerable injury this fall. Migrations from neighboring States have not been observed. Fall sowing of alfalfa and the seeding of winter wheat to avoid serious grasshopper injury promises to be a problem. Considerable injury was evident along the edges of fields of corn, kafir, and alfalfa. More reports of grasshopper injury have come from the western and northeastern parts
of the State than froit other sections.

Tennessee C. Benton (July): The Carolina locust is abundant in pastures
and fields in the southern part of the State. There has been
much complaint of damage to tobacco as well as to clover and
other legumes. Some injury to corn also was observed.




-426

Oklahoma C. F. Stiles (August 1): Grasshoppers are very abund-mnt in the
southwestern and central parts of the State.

Montana R. W. Gjullin (July): A recent survey indicates that Zelanoplus
femur-rubrum DeG, andM. bivittatus Say are fairly abundant in an
extensive area in southeastern Montan, .In the eastern tier of
counties M. mexicanus atlanis Riley, M. packardi ScudI,, a
Dissosteira carolina L. are the dominant species. VWhile grasshoppers do not occur in alarming numbers at present, continued
dry weather and favorable conditions for ogg laying make it
almost certain that grasshoppers in outbreak numbers are to be
expected in these and other scattered areas over the State next
year. In the western portion of the State Comnula pellucida Sci4 reached destructive numbers. There was also. a -severe outbreak of'
M. bivittatus Say in western Montana in Beaverhead County.

Wyoming A. G. Stephens (August 21): Grasshoppers are moderately to
very abundant in the northeastern and central parts of the State.

Nevada G. G. Schweis (Auguist 21): Many species of grasshoppers are
present doing damage in the western part of the State,

Utah G. F. Knowlton (August 3): Grasshoppers continue to be very
abundant and destructive in many parts of Utah.

Arizona C. D. Lebert (July 27): Melanoplus differentialis Tnler and
others of the grasshoppers are very abundant in the Salt River
Valley.

California S. Lockwood (July 27): According to the Monthly News Letter of
Mr. L. A. Burtch, County Agricultural Commissioner of Kern County,
grasshoppers and army worms have not been responsible for commercial damage in his county. His News Letter says, "Approximately
one ton of poison bran mash was put out for grasshoppers at Lebec
and very good kill was obtained."

CUTWORMS (Noctuidae)

Illinois W. P. Flint (August 10): The yellow-striped army worm,
Prodenia ornithomalli Guen., is more abundant in the State than
normally at the present time.

Minnesota A. G. Ruggles (August 20): Noctua fennica Tausch, is very bad
northeast of the Red River Valley.

Wisconsin E. L. Chambers (August 25): The grasshoppers and variegated
cutworm h-ave continued to do unusually severe injury throughout
the State to potatoes, tobacco, small graila and other field
crops, and these, coupled with the unusual7tevere drought we are having in most of the State, have played havoc with our crops in
Wisconsin this year. Owing to the very unusual season and
severe drought, our corn is already going into the silo, and in
the south eantrdl section over one-half of it has already been cut.





-427-Montana R. W. Gjullin (Juky): Pale western cutvorm(Porosagrotis
orthogQni.a Morr,) and army cutworm (Chorizagrotis auxili:
Grote) moths are very abundant.

COTTON LEAF 7UORM (Alaba artillacea Hbn.)

Mississippi State Plant Board, Press Release (August 3): No leaf worms
have yet been found in Mississippi, but they are expected at
any time.

WIREWOPMS (Elateridae)*

New York C. R. Crosby (July 30): Wireworms are causing considerable
injury to oats at Clyer.

South Carolina W. J. Reid, jr. (August 17): Wireworms have been quite
destructive during the past ten days to young cabbage plants.
The crop was seeded directly in the field in hills, the usual
method of planting cabbage during the fall months in this
section. The wireworms attack the plants as soon as gemination
begins, often destroying all plants in the infested hill. From
one to three wireworms have been found feeding on one group of
plants. Fifty per cent of the plant stand has been destroyed on
a ten-acre planting in the Charleston area.

WHITE-LINED SPHINX (Celerio lineata Fab.)

Michigan R. H. Pettit (August 7): We have an abundance of a hawk moth,
Deilephila lineata Fab., this year all over Michigan. Each
mail brings a number of snecimens. As is well known the larvae
of this moth feeds on purslane, a rather troublesome weed.

PAINTED LADY (Vanessa cardui L.)

Vermont H. L. Bailey (August 24): Larvae of the painted lady butterfly
were reported on hollyhocks at Brattleboro.

Minnesota P. E. Derby (August 10): The Canada thistle webworms are
moderately abundant at Barnum, Carlton County.

L. W. Orr (July 16): The thistle butterfly is abundant at
Itasca Park, and there has been a considerable reduction of the growth of Canada tiListle. It is also very abundant at Clarissa,
in Todd County.

A. G. Rug.les and assistants (August): The thistle fly has
been very destructive in Aitkin County. As far as the thistle
fly is concerned it has done more good than harm.

RED SPIDER (Tetranychus telarius L.)

Maine H. 3. Peirson (August 24): Red spiders are on spruce, Orataegus,
elm, yellow birch, ock, and amelanchier in many parts of the State,

South Dckota H. C. Severin (August 20): The red spider is exceedigly
abundant and injurious.

Idaho 0. Wakeland (August 20): The connon red spider is extremely
abundant, since the year is excessively dry. It is affecting
practically all cultivated plants including shade trees and
ornamentals. It has done very severe injury to potatoesoand
beans as well as to the crops ordinarily affected by it.

Utah G. F. Knowlton (August 18): The common red spider has been
damaging raspberries, corn, beans, chrysanthemum, dahlias, peas,
roses, and tomatoes in various northern Utah localities.

Oregon D. C. Mote (August 15): Orchard mites are unusually abundant
this year and doing serious damage to pear foliage in the
Willamette Valley. Reports from other sections of the State
indicate this to be a favorable season for mites, damage being
reported on apples, pears, raspberries, muskmelons, prunes, and
strawberries.

PACIFIC RED SPIDER (Tetranychus pcificus McG.)

California E. A. McGregor (August): It is of interest to record that
during the period from April to July, inclusive, the Pacific red spider (Tetranychus.-acificus McG.) occurred in unusual
severity in central California, causing much damage to vineyardsuLnd
deciduous fruit and ornamental trees. In early August, the
predacious thrips 4Scolothrips sexmaculatus Perg.. ended the
outbreak. This annual phenomenon in central California is very
interesting, since toward the climax the thrips population
builds up so rapidly. that the biological control appears almost
to 'amount to instant annihilation.

JAPANESE BEETLE (Poqpillia japoQnica Newm.)

Delaware L. A. Stearns (August 24): Many reports of injury, especially
on grape, in the vicinity of Wilmington.

Ohio E. W. Mendenhall (August 21): It is reported that the
Japanese beetle was found in Cleveland and Columbus in small numbers, on flowering plants. These were trapped by Japanese
beetle scouts.

ASIATIC GARDEN BEETLE (Aserica castanea Arrow)

Connecticut E. P. Felt (August 21): A specimen of the Japanese garden
beetle, Aserica castanea Arrow, was taken at Stamford.

foliage was reported fro South Bend, July 31. There is every
evidence that this trouble is caused by leafhoppers.


SO YTB.T

GREEM17 CLOVER WORM (Plathypena scabra Fab.)

Virginia H. G. Walker (August 24): The green clover worm has been cansing severe damage to soybeans at various places in this part of
the State.

Mississippi C. Lyle (Agust 25): Several larvae, tentatively identified
by J. M. Langston as Plathypena scabra, were collected on soybeans at Boyle, Bolivar County, on Auast 9. The infestation
was lih-it.

Illinois J. H. Bigor (August 19): The alfalfa looper is very abundant in a field of soybeans in co-nnection with :grasshoppers in
Greene County. 1oout 60 per cent of the leaf surface in the
field has been destroyed by the two pests. The damage is serious because the crop is not ready to cut.

VVEVTBEA CATEPILLAR (.nticarsia Remmatilis Hbn.)

Florida R. N. Lobdell (July 22): The conspicuous feature has been the
very marked increase of parasites over last year. Those are bein- bred out fro-i thousands of caterpillars and are not yet determined. This season has been quite dry so far while last
year was exceptionally rainy. Precipitation at the Station in 1930: May, 4.43 inches; June, 19.61 inches; July 1 to 20, 3.99 inches. Precipitation in 1931: May, 3.16 inches; June, 0.59 inch; July 1 to 20, 1.32 inches; a total difference of 23.96

BEAN LEAF ROLL= (Goniurus proteus L.)

Florida L. N. Lobdell (July): The interestin feature has been that
while in May and early June the bean loaf roller was abundant on
snap beans and soy beans on both mucl and custard apple lands, by this month they have almost completely disappeared from the
muck lands but remain in fair numbers on the sandy custard apple
rides alonr: the l. ke where they are feedin:e on soybeans.

FRUI T INSECTS

APPLE

WOOLLY APHID (Eriosoma lanigerurn Hausm.)

Washington E. J. Newcomer (August 0l): The woolly aphid is probably
more numerous than during any season in the last ten or twelve
years in spite of the great abundance of chrysopids and syrphids.

CODLING MOTH (Carpocapsa pomonella L.)

New York N.Y.State Coll. Agr., Weekly News Letter (August): Rather
heavy dropping as result of the codling moth is reported
quite generally from the upper Hudson River Valley and western
New York. In Oswego County codling moth injury was more
serious this year than during the past three years.
(Abstract, J.A.H.)

Delaware L. A. Stearns (August 4): First second brood larvae spun
up in the insectary today. (Aug. 24): First and second brood
moths emerged at Bridgeville August 21. Infestation is extremely variable this year.

Virginia C. R. Willey (August 28): This insect is fairly abundant
all over the eastern and southern' sections of the State.

Georgia C. H. Aldea (August 22): The codling moth is very abundant
in Cornelia, the injury being severe in some orchards. Thirdgeneration moths are now laying eggs. Broods overlap.

Ohio T. H. Parks(August 24): The codling moth will not very
seriously injure sprayed apples except in Lawrence County, southern Ohio. In that county two extra cover sprays are
bringing the fruit through with fewer worms than last year
but with many "stings" on the fruit.

Indiana J. J. Davis (August 21): Codling moth reports were very bad
at Hobart, August 3. (August 22): The codling moth is moderately abundant throughout the State.

Illinois W. P. Flint(August 10): Southern Illinois- There has been
a big increase in infestation in the Johnson County area in the past two weeks, some sprayed orchards now showing 40 to 50 per cent infestation. There has been a moderate increase during the past week both in mot emergence and in bait-jar
catches. Central Illinois- Collections under bands have
fluctuated slightly during the past week but on the whole have
shown about the same level as for the last two weeks. More than 3,000 larvae were taken under 120 bands in the Urbana
area this week. There has been an increase in the numbers of lpupae found under bands and very heavy emergence of adults is








taking place at the present time (Aug. 8). (Week endin
August 15): Southern Illino.is- Mr. Chandler reports a heavy
emergence of moths beginning aoout August 4 and a heavy catch of moths .in his bait jars, Central Illinois- There has been .an increase in emergence in central Illinois during the last
several days but a decided drop in the numbers of larva@
taken.under bands. The number taken inder 120 bands this week
was more than 1,000 less than the number taken under the same
number of bands last week. It seems likely that the cool
Weather just passed will stop pupacionl as usually happens when a cool period of this sort occurs at this time of the
year.

Michigan R. Hutson (August 24): The codling moth is very abundant.

Wisconsin E. L. Chambers (August 24): The codling moth is moderately
abundant. This insect is very abundant where spraying is not
done.

Missouri L. Haseman (July and August): A peak of second-brood moths
occurred between July 10 and 15 and on July 25 evidence of the
second peak was showing up. The pest is very serious -gain
this summer. Moths of the third generation were emerging in
central Missouri and some of their worms beginning to enter
fruit on August 25.

Nebraska M. H. Swenk (July 15 Aug. 1): The codling moth of the
first brood started emerging July 4, reached the crest of emergence on July 15, and they are now largely out. Egg
laying began on July 13,. and the first-brood larvae hatched
on July 16, which is 4 days earlier than in 1930, 6 days
earlier than in 1929, and 11 days earlier than in 1928.

Nevada G. G. Schweis (August 21): The unsprayed apples are all
wormyr in the western part of the State.

Washington Ortho News, Vol. 3, No. 8 (August 20): The first-brood
moth flight this year showed two fairly distinct peak periods, the first coming about the middle of May and the second during
the last week of that month. The second-brood flight has
shown a series of "peaks," the two heaviest and most sustained
coming during the last week in July and about the middle of
August, respectively. There have been in addition several intermittent high catches, together with moderately good catches
throughout the entire second-brood period, from about the
.1st of July up to the present time.
In general the second rood has far exceeded expectation, being the heaviest flight in many years, making even the
season of 1929 look ordinary by comparison. It remains to be
seen just what the third brood will produce.






-440

Oregon D. C, Mote (August 15):. B. G. Thompson reports the peak
of egg laying by the second brood. Recent cool nights have
prevented much egg laying.

APPLE AND THORNT SEELETONIZFR,(Hemerophila ariana Clerck)

New York N.Y. State Coll. Agr., Weelly News Letter (August): The
apple and thorn skeletonizer seriously affected many orchards
in Niagara County. (Abstract, J.A.H.)

YELOW-IECIKED CATERPILLAR (Datana ministra Drury)

Ohio E. W. Mendenhall (August 14): The fellow-necked caterpillar
is doing some damage to apple stock in nurseries in Morgan
County.

T. H. Parks (August 24): The yellow-necked caterpillars were sent in August 21 with the statement that they were
attackldng apple foliage in a Jefferson County orchard.

APPLE LEAFHOPPERS (Cicadellidae)

Massachusetts Massachusetts Fruit Growerst Association, the Pest Situation
(Agust 1): Leafhioppers have been very abundant generally,
with especially heavy infestation in southeastern Massachusetts. The hatching period of the first brood was long drawn out so that it was often impossible to control the insects by the use of one spraying. Many growers secured good control by
adding nicotine to the calyx and first cover sprays.

Connecticut P. Garman (August 21): The rose leafhopper (Emp rosae L.)
appeared in abundance in June, became fairly abundant in July, and decreased rapidly toward the middle of the month. Secondbrood nymphs were present only in a few orchards and there in
very sraall numbers.

Delaware L. A. Stearns (August 24): Apple leafhoppers are still
rather abundant throughout the State.

North Carolina Z. P. Metcalf (August): Apple leafhoppers are very abund=.t
in eastern North Carolina.

Ohio T. H. Parks (August 24): Apple leafhoppers are more abundant
than usual on apple foliage.

APPLE LACE BUG (Corythucha coelata Uhl.)

Oregon Oregon Agr. Coll., Insect Best Report (July): Apple lace
bugs are very abundant throughout Yamhill County on apples.





-441

SAN JOSE SCALE (Asnidiotus oerniciosus Comst.)

Georgia C. H. Alden (August 22): The San Jose scale is scarce in
CorneliL.,

Ohio E. W. Mendenhall (August 14): The infestation is greater
in southeastern Ohio than it has been and it will mean a little
harder fight to keep it in check.

Indiana J. J. Davis (August 22): The San Jose scale is moderately
abundant throughout the State, especially in the southern part
of the State.

Illinois W7. P. Flint (August 15): Infestation has been higher in both
central and ,outhern Illinois during the last few wecks. There
will probably be a considerable number of heavily infested
orchards by the end of the season.

Wisconsin E. L. Chambers (August 24): The San Jose scale is moderately
abundant. Several additional infested areas have been discovered.

Missouri L. Haseman (August 25): The San Jose scale has shown serious
increase during the month. Earlier it was scarce.

Mississippi State Plant Board (August 3): The San Jose scale is doing
considerable damage to peach and plum trees throughout the State.

Oregon Oregon Agr. Coll., Insect Pest Report (July): This scale is
moderately abundant throughout the State and was reported as
very abundant in Morrow County.

APPLE MAGGOT (Rhaoletis pomonella Walsh)

Massachusetts Massachusetts Fruit Growerst Association, The Pest Situation
(uhgust 1): Apple maggot flies were first observed the last
few days of June and by July 8 to 10 were beginning to appear
in numbers.

Tew York N. Y. State Coll. Agr., Weekly !ews Letter (August): During
the first week in August nple r -ots were ovipositing in the
Hudson River Valley. (Abstract, J.A.H.)

N ew York N. Y. iState Coll. Agr., Wee-ly News Letter (August 17): The
injury caused by the feeding of the newo generation of the apple
curculio adults is severe in several Essex County orchards.
The beetles are somewhat susceptible to poisons at this stage.
The varieties most severely attacked are Tol:nan Sweet, ,ealthy,
and Spy.







-442

WESTERN ROSE-CHTFER (Macrodactylus uniforms Horn)

Arizona C. D. Lebert (July 28): Considerable injury on apple trees
at Ft. Huachuca, July 14.

RED SPID1 (Tetranychus telarius L.)

Pacific
Northwest Ortho News, Vol. 3, No. 7. (August 7): It is not a difficult
matter at the present time to pick out orchards severely infested with the two-spotted mite, because of the browning,
rnast, or dust covered foli.age.

Oregon Oreg. Agr. Coll., Insect Pest Report: The red spider is
very abundant, mostly on mountain ash in Baker County and on pears and apples throughout Jackson County. Moderately abundant in Douglas County and on pears and strawberries in
Josephine County.

P2ACH

ORIENTAI FRUIT MOTH (Laspeyresia molesta Busck)

Connecticut P. Garman (August 21): The third brood of the oriental piach
moth has not yet appeared in force. What few early peaches
have been picked seem to be fairly clean.

Rhode Island A. E. SteM (July 28): The oriental fruit moth is moderately
abundant.

New York N. Y. State Coll. Agr., Weekly News Letter (August): Oriental
peach moth infestation in fruit of early peach varieties seemed
to be heavier than. last year in Dutchess County, while in
Niagara Comunty there Was considOerdle wormy peach fruit and
quinces were riddled as'usual. (Abostract, J.A.H.)

Delaware L. A. Stearns (August 24): Parasitism of the ~"t brood of
the oriental fruit moth was light, 13 per cent; of the second
brood heavy, 80 por cent, by Miacrocentus sp. Infestation of
early peaches was light.

Pani: V& J. R. Stear (August 24): The oriental fruit moth is scarce.
There has been practically no terminal injury on 500 2-year-old
trees.

West. Virginia L. M. Peairs (July 31): The oriental: fruit moth is scarce in
various sections, much less abundant than in 1929.

Virginia W. S. Hough and L. R. Ca-le (Au-Ust 24): The oriental fruit
moth is mndcrately abundant at Vienna but scarce at Eoar-oke.




-443

Georgia 0. I. Snapp (August 20): Less than one-half of 1 per cent
of the latest maturing commercial variety of peaches was
infested by this insect at Fort Valley this year.

C. H. Alden (August 22): The oriental fruit moth is scarce at Cornelia. Only 3.3 per cent is wormy in unsprayed plats as
compared with 11.5 per cent in 1930.

Ohio T. H. Parks (August 22): The oriental fruit moth is moderately
abundant. It is most common in laJ:e-shore areas.

Indiana J. J. Davis (August 22): The oriental fruit moth is moderately
abundant throughout the State.

Illinois W. P. Flint (August): August 10, southern Illinois- There has
been a slight increase in the visible infestation of peaches in
Pulaski County. All growers of Slappy peaches in this section
report fruit (now all picked) much less infested than in 1929
but still with some little injury showing. In Union, Jackson, Johnson, and Marion Counties increase, if any, was too slight to be noticed. No recent twig injury in any county. To date can see no possibility of com .:ercial damage to Elberta unless
it beAin Pulaski County. Central Illinois- So far this year no
oriental fruit moth infestation has been found in the Urbana

local; only one grove has been observed where these worms are
doing commercial damage. At the present time about 25 per cent of the twigs have succulent growth and approximately 90 per cent
of that growth has been attacked in Lzkeland. The majority of
the larvae are about mature at the present time; the bags are
on the main mature leaves and twigs.

Ohio T. H. Parks (August 24): Many complaints have come in concerning bagworm injury to arborvitae and other evergreen plantings,
also to some shade trees. The worms are now full grown iad
feeding is about over. There are many more present than usual.

noticeable feotding. Thne 3erkshire section of Massachusetts had the worst infestation with about 600 acres of btaech and
maple showing some dloEree of 'feedin- u-r to- complete stripping.
In southern Vermnt bout 10 acres w7ere reported from 25 up to 75 per cent defoliated.. The infestation in the White Mountrain

states that itthe degree of in-Cestatior. in Noew Hr ,pshirc is nnuch
lighter th;an last year, zaoout 50 per cent peri-aps; in 1.!:ine it
is about 10 to 20 per cent lighter, although 1'.f the hea-vily infested territory it i-0 slightly onvr." E~r. Wooldri4j;e reports that most of-the dhrmage he hns seen was in southern
New Hnmpshire, although isolated cat~ were :,otod Cs far i-.orth
as 41lton, New Hampshire. The apple trees were most corronly attacked, though marw other species of trees were also found

through a very dense migration of butterflies. The butterflies were first encountered not far north of Weed, and we passed out of the migration not far south of Dunsnniir, the zone of flight being about 35 miles wide. The butterflies were traveling in
a general westerly direction. Possibly 90 per cent of the
individuals ware not over 3 feet above the ground; very few were
as high as the windshield of the car; an occasional individual
flew as high as 10 feet. Roughly there appeared to be about
one individual to each 100 feet of land surface. Upon inquiry
the writer was told that July 25 was the fourth day of the
migration.

MEALY FLATA (Ormenis pruinosa Say)
Massachusetts A. P. Morse (August 3):: This lantern-fly has been in evidence
locally at Wellesley recently, showing quite an outbreak, but not

7HI EFLIES (AleyroLtLi)

Georgia 0O I. Snapp (August 14): Whiteflies were not as abundant as
usual during the summer months, Crepe myrtle is ~a favorite host
and this plant frequently fails to bloom when whiteflies are
abundant. This summer crepe myrtle is blooming abundantly in all lotions, which I believe is due to the absence of damage
caused by the feeding of these insects.

PLANT QUAANTIN2 A11 D C0NT2OL ADMINISTATION

Notes abstracted from "News Letter," August, 1931

(Not for publication)

GIPSY MIOTH (Porthetria dispar L.)

During July each year inforation is gathered as to the amount of defoliation caused by the gipnsy moth. Last year there was considerably less reported than the previous year, and early indications are that there will be less reported this season than last year. There is, however, severe defoliation in the area in Massachusetts south of 3rockton, which will be roorted on later..

A larva of the Fipy '-oth was intercepted at Seattle on an Azalea plant in furnishings from Japan. In 1930 both larvae and pupae of this insect were found at Honolulu, Hawaii, on maple, pine, and rose fro-- Japan. The gisy moth is .uore com-only intercepted in the egg stage.

B70WN-TAIL MOTH (Ny7ia p]haerrhooa Don.)

Evidence based on the number of brown-tail webs which were cut in New
England during the winter of 1930-31 showed that this insect was more abundant than usual in some sections. This Was particularly true in southwestern Maine where the infestation was especially heavy on small groups of apple trees in villages. This also applies to a considerable extent in central and southeastern New Hampshire. In Massachusetts the webs are cut annually rather consistently by the local moth superintendents, and considerable less webs were cut last winter than during the previous winter. In Maine a total of 320,954 webs and 69 bushels of webs were cut in the 9 towns which reported, the greatest number for any one town being 307,000 webs at Biddeford. In New Hampshire a total of 655,076 webs were cut in 50 towns, the greatest number in any one town being 80,757 at Pembroke. In Massachusetts there were 36,564 webs and 312- bushels cut in the winter of 1930-31 as compared with 75,684 webs and 307 bushels cut the previous winter. In some cases the number of webs cut are reported by bushels. It is practically impossible to arrive at the average number of webs in a bushel for they vary greatly in size and also in the amount of tw ri that is left on each web. Figures range from 1,500 to 2,800 webs to th bushel, and if we take as an average 2,000 webs to the bushel, it gives us 763,000 webs. Using this figure, with the 1,012,604 webs which were reported cut, gives a grand total of 1,775,604 webs cut and destroyed during the winter of 1930-31 in New England. Vebs were cut in several other towns especially in Maine, but no record as to thenumber is available.

PIiK BOLL ORI (Pectinorhora :ossypiella Saund.)

The field inspection p-erformed in the Salt River Valley of Arizona prior to July 1 has been more or less at random, in an endeavor to locate infested fields. At this time 6 such fields have been found, 3 south of Laveen and 3 in the Goodyear-to-Queen Creek area. Beginning with July, weekly infestation counts are to be made from some 20 fields in the Salt River Valley and several fields in the vicinity of Coolidge and Cas' Grande in the Gila Valley. Some
of the fields are in stub cotton and others in nlantued cotton of both short

INSECT CONDITIONS IN PORTO RICO DURING JULY, 1931 M. D. Leonard
Insular Experiment Station, Rio Piedras, Porto Rico


a Two adults of the coconut rhinoceros beetle, Strataegus quadrifoveatus Beauv., were received under date of July 16 from Alberto Correa from Utuado with the statement that they were found eating the shoots of young cane plants; the injury was noted in several places near Utuado. (M.D.L. and F. Sein.)

Adults of Ligrus tumulosus Burm. were abundant at lights during the
month at Isabela and many were being eaten by the imported toad, Bufo marinus L. (G.N.W.)

Dyscinetus barbatus Fab. adults were absent at lights during the whole month. (G. N.W.)

The leafhopper Protalebra brasiliensis DeLong, known to attack sugarcane occasionally, continued to be abundant throughout the month on Bidens pilosa on the El Morro Golf Course in San Juan. (M.D.L.)

Mr. Fletcher, Manager of Hill Bros. Co., a large cannery located in Rio Piedras, stated on July 22 that all during the past fiscal year the weevils Dia-prepes spengleri L. had done damage by stripping the foliage on a considerable number of young trees in his grove at Manati, necessitating much handpicking of the weevils by boys. He stated that less trouble was experienced in his Rio Piedras grove. (M.D.L.)

The weevil Lachnopus curvipes Fab. has been locally more abundant around Isabela than the common "vqquita" (Diaprepes abbreviatus L.) which causes the bulk of the injury to the leaves. (G.N.W.)

The orange dog, Papilio androgeus Oramer. On July 12 a butterfly emerged from a caterpillar found on grapefruit foliage at Isabela some time previous. On the same day two other caterpillars were brou&-ght in. (G.N.I.)

The papaya fruit-fly, Toxotrypana curvicauda Gerst., was sent in under date of July 8 by T. B. McClolland from the Mayaeuez Experiment Station in a rather small and rather green fruit which contained 14 newly formed puparia and one full-grown larva. (M.D.L.)

One fruit was found infested at the substation at Isabela on July 3 and sometime during the month nearly all of the fruit on several plants in a farm near Aguadilla were infested. (G.N.W .)

The introduced ladybird beetle Cryptolaemus montrouzieri Muls. was observed during the month, but not very cotmonly, at Isabola feeding on a soft scale. (G.N.W.) The scale may possibly be Pulvinaria psidii Mask., since there is a previous record on this host plant and scale for the ladybird in Porto Rico.






-493

The cotton leaf worm, Alabama argillacea Hbn., occurred in destructive
numbers in the whole North Coast cotton section during the month, but was most injurious around Isabela and Camuy. (M.D.L.)

The pink boll worm, PectinoThora gossyniella Saund., was generally distributed throughout the whole cotton-growing section of the North Coast, the least injury being at Isabela and the heaviest around Arecibo and Aguadilla. (M.D.L.)

Cotton stainers, Dysdercus andreae L., were more or less general in the North Coast cotton section, but doing little injury. (M.D.L.)

Diabrotica grarinea Baly was abundant and injurious to corn at Isabela during the month. (G. NT. I.)

The alfalfa leaf-tier, Dichomeris piperatus Wlsm., was destructively
abundant during the month at Isabela in one patch, rendering the alfalfa worthless for feeding. (G.N.W .)

The velvety cutworm, Prodenia ornithogalli Guen., was abundant at Isabela attacking a wide variety of hosts including alfelfa, crotalaria., and tomatoes
besides numerous weeds. (G.N.W.)

Many specimens of Nezarae. mrrginata 3eauv. clustered on a single pod of crotalaria at Isabela. (G.N. .)

Injury to "gramma" grass (St. Augustine grass) by Psara Phaepteralis
Guen. was reported in July, the grass on a large Irwn being more severely affected in the shade than in the sun. (3. Y.)

The sugarcane looper, Aocis) Remigia repanda Fab., defoliated a small area of Para or malojillo grass (Panicum barbinoda), young plant cane, and half-grown elephant grass (Pennicetum glaucm). (-...)

The velvet-bean caterpillar, Anticarsia genmatilis Hbn., was abundant on the foliage of alfalfa and sword beans at Isabela e.during the month. (G.Y.7.)

The bean leaf-wvebber, Kacoleia indic ta Fab., moderately infested a good sized patch of pole limas throughout the month -It the Station at Rio Piedras. (M.D.L.)

The bean lace-bug, Corythucha gossynii Fab., was also present on the pole limas, but not very injurious although it increased somewhat towards the latter part of the month. (M.D.L.)

The bean leaf-roller, Eudamus roteus L., was present bu:t only modera3tely injurious in a good-sized ratch of pole limn at the station in Rio Fiedras. (M.D.L.)





-494
The potto :lIfopir> 3 2_ca fabae Harr.was present in moderate
numbers in the same patch of pole linas at the Station in Rio Piedras (M.D.L.)

Diabrotica innuba Fab. was quite abundant on cantaloupes at Isabela.(G.N.W.)

The melon worm, Dianhania h4yainata L., was observed on July 31 to be considerably injuring the leaves and blossom buds of a fthr-sized patch of cucumbers at the Station in Rio Piedras. The vines were just beginning to run by
the end of the month and no fruit had set as yet. (M.D.L.)

Four moths of Linh'mnla gi il were reared from chayote (Sechium edule.) (F. Sein.)

A mealybug, -presumably Pseudococcus citri Risso, was found on July 2
to be moderately infesting several celery plants (one badly infested) at the Station on grounds at Rio Piedras. The bugs were clustered at the base of the stalks just above the ground, Dend a few were on the roots. We have only one previous record of injury to celery in Porto Rico by this insect, collected by T. H. Jones, July 3, 1912, Rio Piedras, determined by H. '.orrison. (M.D.L. and F. Sein.)

Diabrotica graminea Baly was fairly abundant and doing moderate damage in a 1-acre planting of okra in Trujillo Alto on July 10. Most of the plants had finished bearing, however. (A. S. ills.)

The pink boll worm, Pectinomhora 7os!ypiclla Saund., was found on July 10 infesting 10 out of 16 pods examined in a 1-acre planting of okra at Trujillo Alto. The okra adjoined a field of about 11 acres of cotton which shoved about 85 per cent infested bolls. The okra plants examined were situated near the edge of the field next to the cotton. The infested pods were all mature, at least 3 or 4 inches in length, and each contained 1 or 2 larvae, and several pupae were found within the nods. The cotton was an old field which had been infested for some ti-ne. (A.S. Iills.)

The canna leaf-roller, Calvodes ethlius Cram., became destructively abundant during the month on a numit- of -plants at Isabela, averaging one or two larvae per plant. (G. ]T.)

The Hawaiian beet webworm, FEgenia fascialis Cram., was abundant on July 12 (when first noticed) and through the rest of the month on several large patches of a wveed, Gonhrena disnersa, locally call "arraza contodo." The moths were much in evidence and the l~,rvae were v:ebbi.ng together and skelotonizing the leaves to a considerable extent on the El Morro Golf Course in San Juan. (M.D.L.)
