THE MORE IMPORTANT RECORDS :OR SEPTFRBER, 1932

The situation with respect to the principal insects attacking field crops, including grasshoppers, white grubs, Hessian fly, chinch bug, and corn ear Worm, has not materially changed since our September 1st rep-nort.

Two flower beetles (Raphoria inda L. anrid E. sepulchralis Fab.) were attracting attention by injuring vegetables and flowers throughout the Mississippi Valley region from North Dakota to the Gulf.

The southern corn stalk borer was reported as unusually abundant in North Carolina, as high as 95 per cent of the stalks in some fields being infested, and in some instances heavy infestation caused considerable breakage of stalks.

What is believed to be the beet webworm seriously infested alfalfa fields in Duchesne and Uintah Counties, Utah, this year. This is the only serious outbreak of this insect in this State during the past ten years.

From present indications it appears that the plum curculio will hibernate this fall in greater numbers than it did last year in Georgia.

Probably in consequence of the continued rainfall deficiencies over parts of the East Central States, damage by the shot-hole borer is decidedly more prevalent in deciduous orchards than usual in that region.

A red spider (Tetranychus pacificus McG.) has apparently extended its range from San Joaquin and Stanislaus Counties to Fresno, Tulare, and Kern Counties in California. This insect is one of the serious vinifera grape pests.

An unusually heavy population of the pecan leaf case bearer is entering hibernation in southern CGeorgia, indicating serious infestations next spring.

A new infestation of the citrus whitefly has been found about 4 miles northeast of the infestation at Pasadena, Calif., discovered last summer.

Blister beetles continued to be very destructive to truck and ornamental crops along the south Atlantic seaboard and in the lower Mississippi Valley.

The banded cucumber beetle is occurring in very destructive numbers in
Louisiana, Mississippi, Alabama, and Georgia, where it is damaging beans, sweetpotatoes, and other truck crops.


,343-








The Mexican bean beetle has been found as far north as central New Hampshire and has been destructively abundant farther north in Indiana than during any nrcvfvz yer.

Thc cabbage webworm was causing considerable damage througThout the South Atlantic and Gulf States.

Fall webworms (Hy)hantria cunea Drury and H. textor Harr.) were reported as unusually prevalent throughout the New England, Middle Atlantic, South Atlantic, East Central, and Lower Mississippi Valley States.

A very heavy infestation of forest trees by Walkingsticks resulting in severe defoliation was reported from limited areas in southern Pennsylvania.



THE MORE IMPORTANTT ENTOMOLOGICAL FEATURES IN CANADA FOR AUGUST AND SEPTEMBER, 1932

Combative measures against grasshoppers were carried out over a wide territory in the Prairie Provinces. A survey of the situation in Manitoba, where the outbreak is most severe, showed that while large areas of cros had been saved through the application of poisoned bait, considerable damage has been done in some localities, not only to grain crops, but also to fodder and market garden crops. Surveys by provincial and federal officers are being continued in the three affected provinces. Throughout British Columbia grasshoppers continue unusually scarce.

Wire=orms have caused much damage in Saskatchewan, particularly in the territory northeast of Saskatoon, where they appear to be increasing.

The infestation of white grubs is heavier over eastern Ontario than in the southern and central parts of Quebec. The grubs are in the destructive secondyear stage in the latter province and are causing heavy damage to crops.

The bertha armnyworm is recorded for the first time from the Pacific coast region of British Columbia, at Massett, Queen Charlotte Islands.

Present indications are that unless control measures are taken this fall, there ;.ill be a serious outbreak of the Hessian fly in Ontario next year.

The corn ear worm is effecting marked damage to conning corn in sections
of southern Ontario.

Heavy infestations of the wheat stem sawfly are reoortci from parts of Manitoba and Saskatchewan. In the latter Trovince the wheat stem maggot occurs generally and is causing moderate damage.

The gladiolus thrips continues to be a serious pest of gladioli in Ontario. It is reported to be more noticeable in southern Quebec than was the case last year.

A European mirid, Melanotrichus concolor Kirsch, has been taken for the first time in Canada, at Nanaimo, B. C. This insect attacks broom- which is more or less of -a nest in the redon where the insect has been found.








-345

The outbreak of sod webworms (Crambus sp. ), which caused material damage
to lawns and grass sod in southwestern Ontario.in 1931, appears to have completely subsided, no infestations having been found this season.

The Mexican bean beetle is occurring in many localities in southern Ontario. It is more prevalent than previously recorded, and in some instances has caused quite severe damage in market gardens. Weather conditions have been favorable to its dcveloopment this year.

Indications point to a more than usually heavy infestation of the imported .cabbage worm in Ontario with resulting severe damage to cruciferous crops.

A marked reduction in the amount of codling moth injury in the Niagara district, Ont., is believed probable, as weather conditions have been unfavorable to the insect. In unsnrayed orchards of eastern Ontario, however, damage to fruit by this species is quite striking.

In the Gasp-e Peninsula of Quebec only a small percentage of the larvae of the Euronean sawfly Dinrion polytomum Hart., which overwintered in cocoons in the ground, emerged this year. Defoliation of white and black spruce is much lighter this season than in 1931. A serious outbreak of the eastern spruce beetle has developed over a large oart of this territory.

The balsoan woolly aphid is spreading in the Maritime Provinces, and the
associated gout disease has become.. eneral in Nova Scotia.

The infestation of the beech scale continues to develop in Nova Scotia and southern New Brunswick and many' trees are dying, particularly in western Nova Scotia.

The walnut caterpillar is very prevalent in southern Ontario, where the majority of black walnut trees have been -artially or wholly defoliated by this insect.

In certain localities in Manitoba and Saskatchiewan, willows and poplars
have suffered severe defoliation by the willor leaf beetle. In sandy sections of Manitoba an outbreak of the aspen poplar leaf beetle has occurred.

There are indications that the severe outbreak of bark beetles in yellow pine in the Aspen Grove area of british Columbia is now subsiding.

the Valley before. Heretofore the infestation has been restricted to the
mountain and hillside areas. Invasion of the cultivated fields in the Jensen
district was prevented this sumrner b the Green River forming a barrier to
the insects. The cultivated crops, consisting, in the main, of garden crops, corn, and potatoes, on the half-dozen ranches located on the east side of the
Green River were completely devoured by the migrating crickets within about
three days. (Det. by W.W. Henderson.)

Southeastern United States. R. A. St. George (September 26): Reports from a
nurser located near Raleih, 1. Car., indicate that the extensive injury that was caused by the activity of white grb larvae to the roots of pine seedlings
during. the early smnmer months has subsided durin Septe:mber. An ex7aination of the soil revealed the percentage of large numbers of grubs which had been
parasitized. Many wasps were found flyrin- over the seed beds and di;:ing
into the ground during the month. Several were submitted for determination
and were found to be Campsomeris (Trielis) octomaculata race hermione (Bars).
They are known to be parasitic on wite -rub larvae. Several species of
Phyllophaga larvae have been receive frorn the vicinit,.
Other reports from a nursery near Columbia, S. Car., indicate that the
activity of the grubs may have been influenced somewhat by moisture conditions
of the soil. A condition of droughthas been experienced during the early
spring and suamer months in the vicinit-, and very few grubs have been found.
During last fall they were present in large numbers and very destructive.
During Auzust an examination of the soil to a depth of 4 feet did not reveal
their presence.

North Carolina. J. S. P.incmkney through C. C. Hill (June 30): A summer survey of

State infestation 4.5

Ohio. T. H. Parks (September 20): While we had three times as many flaxseeds
present in the 1932 crop as in the crop of 1931, very few flies have yet
emerged and only a small number of eggs have been laid. The late sum-:er and
fall have been very dry with no rains to moisten the flaxseeds and hasten
pupation. We are stressing the safe sowing dates this year. Hessian flies
are moderately abundant--most abundant since 1920 and more than average.

Michigan. R. Hutson (September 26): The Hessian fly is moderately abundant.

Iowa. H. E. Jaques (September): The Hessian fly is scarce in Osceola, Crawford,
Adams, Madison, Warren, Monroe, and Henry Counties. It is moderately abundant
in Harrison, Mills, Montgomery, and Clinton Counties.

Missouri. L. Haseman (September 27): Breeding cage records for central and southeastern Missouri indicate that the flies began emerging earlier than usual this
fall. Parasites in central Missouri are very abundant. One sample shows 56 per cent flax seeds parasitized, 37 per cent dead of disease apparently, and
only 7 per cent alive. Some breeding cages are giving us no adults at all.

Nebraska. M. H. Swenk (August 25 to September 20): In Nebraska there are two
distinct areas of infestation with the --essian fly. The eastern area includes southeastern Nebraska, west to about Webster, and Howard Counties, and north to
Nance, Platte, and Douglas Counties, and the infestation is heaviest to-ard
the western end of this area. The western area of infestation centers in Phelps
and Kearney Counties, but takes in parts of the adjoining counties. Weather
conditions in these two areas have been quite different during the summer, the
August rainfall in the more eastern area having-, been almost twice te normal,
.........~ u ve o tice the normal,
while in the western area it was less than normal. As a result, over a large portion of southeastern Nebraska Hessian fly emergence to date (September 20)
has been only a little later than normal. This has especially been true in
some of the eastern and extreme southeastern counties, where normal or greater
rainfall was received during the month of August. In general, the emergence
in r-the counties west to Jefferson and Nance Counties, and thence northward, is
not very far from normal, though in some of the included counties it may be a few dams later. But there is a group of counties in south-central Nebraska
where rainfall has been deficient and in these emergence has been delayed.
According to our present information, in several counties wVest and south of Fillmore County emergence is delayed about as at our Fillmore County field
observation station, where on September 20 about 25 per cent of the flics of
the main fall brood had emerged. In a group of counties still farther south and
west emergence is still more delayed, about as at our Phelos county field











observation station, where on-September 20 only about 10,por cent of th-Ie flies had werred It is very likely that wh'eat sowing will need to be dela-ed more
t~ri usull"late in these ;7e-te'n areas this fall.

Kai s--a H. R. Bryson (September 21): Observations rezardinz the abundance of
He(ss ian fly ?,t Manhattan. reveal the fact thiat a small earlyv fall cmenstrnce
gav(e, rise to a very few flaxseeduin the volunteer wheat. A mutch larger
e>,.er~ence tookc place durin- the second week- of September. Small larvae are

Minnesota. A. G. Ruggles (September 26): The corn ear wqor is very abundant
around St. Paul and Minneapolis.

Iowa. H. E. Jaques (September): The corn ear worn has shown up abundantly in
late corn.

Missouri. L. Haeman (September 27): Where rainfall has been difiKe.t, a large
population will again go into winter quarters, but the situation is less
serious than last fall.

Kansas. H. R. Bryson (September 26): Late sweet corn at Manhattan is heavily
infected.

Oklahoma. C. F. Stiles (September 23): The corn ear worm is very abundant in
the greater part of the State. It is abundant in cotton bolls and in heads of
grain sorghums.

Idaho. R. W. Haegele (September 21): In southwestern Idaho all field corn is
badl:y infested. Approximately 80 to 90 per cent of the ears show some damage
with the feeding seldom extending more than 1 inch back on the tip of the ear.

FALL ARMYWORIM (Lap1yma fruziperda S. & A.) Florida. F. S. Chamberlin (September 6): The armyworm is prevalent over most of
Gadsden County. Severe injury is confined to small areas at the present time.

Maryland. E. N. Cory (September 22): Fall armyworm reported in Cecil County.

STALK BORER (Papaipema nebris nitela Guen ) New Jersey. T. J. Headlee (Septerber 6): The stalk borer is moderately abundant. Kentuc:y. W. A. Price (September 26): The stalk borer is moderately abundant on
dahlias and corn.

Michigan. R. Rutson (September 26): The stalk borer is moderately abundant.

SOUTETD CORN STALK BORR (Diatraea crambidoides Grote)

Virginia. H. G. Walker (September 27): The larger stalk borer is verve abundant.
Practically 100 per cent of the stalks are infested in some fields in Norfolk. North Carolina. W. A. Thomas (September 21): Late corn at Chadbourn h.as been
subjected to attacl:s to a greater extent this season than in former years.
The injury has been so severe as to cause much of the corn to break off at the
ground before reaching maturity. Fully 95 per cent of a field of corn near
the laboratory was found to be infested.

CHINCH BUG (Blissus leucopterus Say)

Qonnecticut. .,R. B. Friend. (September 20): In three instances in New Haven the.
Trass in large lawns has been almost entirely killed.






-354

Ohio. T. H. Parks (September 15): Chinch bugs are very abundant in many cornfields of northwestern Ohio. The second generation is now from one-half to
full 7rown and has caused some injury. We now have a population capable of
doing very serious damage next year unless controlled.

Illinois. M. D. Farrar. (September): The chinch bug is moderately abundant in
central Illinois but above normal for this area.
J. H. Bigger (September): .Chinch bugs are very abundant. A chinch bug survey,
September 1 to 10, indicates area of danger to next year's crops in all the
central portion of Illinois a:daconsiderable area on the western border of
State, with possible danger of infestation in area between.

Wisconsin. E. L. Chambers (September 27): Chinch bugs in Pepin, Buffalo, Pierce,
and Trempealeau Counties proved to be serious for the first time in many ears
and continued until the corn was cut for the silo.

Iowa. H. E. Jaques (September): Chinch bugs have been much in evidence in sluthern Iowa all summer and seem to threaten serious danger for next --ear.

lNebraska. M. H. Swenk (September 20): The chinch bug is moderately abundant in
southeastern Nebraska.

Kansas. H. R. Br-rson (September 21): The second generation was quite aba dant in
fields in south-central and eastern Kansas. Injury to sorghums was very much
in evidence during August through Butler, Greenwood, Chase, Allen, Lyon,
Anderson, Coffey, Franklin, and Miami Counties. The extremely dry weather in Butler County aided the bugs in their destruction. Chinch bugs of the second
generation killed out a few of the more susceptible varieties of sorghum s in the sorghum breeding nursery at the college farm this summer. A correspondence report from Hazelton, Barber County, also records chinch bugs injuring
kafir.

COPN LEAF APHID (Aphis maidis Fitch)

North Carolina. W. A. Thomas (August 25): A very heavy infestation is now
present on late corn at Chadbourn, attracting large numbers of Diptera and
Hymenoptera on these plants. In some instances the leaves and stems of the
corn plants are completely covered with aphids. This, no doubt, will somewhat
reduce the yield of grain on the infested plants.

SAY'S STIh., BUG (Chlorochroa sayj Stal)

New Mexico. J. R. Ever (September 1): A recently reported pest is the grain bug
(Chlorochroa s -) which has appeared all over the State and is particularly
injurious to kafir corn in western New Mexico.

ALFALFA

ALFALFA WEEVIL (,ypera postica Gyll.)

Utah. C. J. Sorenson (Season 1931 and 1932): Seven years ago the alfalfa weevil
was practically unknown in the Uintah Basin. Since 1925 it has -radually spread and increased until practicall, every alfalfa field suffered considerable damage
in 1932. The first serious damage for the Basin as a whole occurred in 1931.







-355

California. A. E. Michelbacher (September 19): The alfalfa weevil at both
Pleasanton and Niles can be found in about the same numbers as a month age.
Larvae in all stages of development can be collected. In the Pleasanton area
the weevils are rather scarce, while around Niles they can be f-und rather
easily.

BWM WESWORM (Loxostege sticticalis L.)

Utah. C. J. Sorenson (July 3 to Au~gust 1): This is the first year within the
past ten, at least, that this insect has been recognized as doing denate in
alfalfa fields of Duchesne and Uintah Counties. Larvae and moths were present
in varying numbers in practically all alfalfa fields. In about 10 or 15 fields
in widely separated areas, serious danage was done in fields of from 20 to 100 acres. Moths became very numerous beginning August 1, in the vicinity of these latter fields, and there were some moths in all fields after the latter date to September 1. Neither eggs nor larvae resulting from the August brood of moths
could be found up to September 5.


FRUIT INSECTS

APPLE

CODLING MOTH (Carpocapsa pomonella L.)

Georgia. C. H. Alden (September 21): The codling moth is moderately abundant at
Cornelia. Very few larvae are pupating under the bands. A few moths are
being caught in the bait traps.

Ohio. T. H. Parks (September 21): The codling moth is moderately abundant--nore
so than average.

Illinois. W. P. Flint. (September 22): The coIling moth continued to emere and
enter apples during the first half of Septemoer. In many orchards more damage was done to Jonathan and Grimes during this period than at any other time during the year.

ansas. H. R. Bruson (September 26): The codling moth has been unusuall.- destructive in Kansas this season. This situation may be attributed to three things; namely, the heav-y carr--over of noths from the 1931 season, weather conditions which were favorable to the moth, and a very light set of fruit.

Arkansas. D. Isely (September 28S): The codlin; moth has been unusually destructive, probably ca-_sing a larger percentage of loss to the apple crop than in any
year since 1918, with the possible exception of 1925.

Colorado. G. M. List (September 20): The codling moth is very abundant in Mesa
County, and moderately abundant in other sectiQons.

Idaho. R. W. Haegele (Septecber 21): Injury is greater than normal in the fruit
district of southwestern Idaho.

rew Mexico. J. R. I-er (Septedber 1): Codling noths are giving us considerable
trouble this season.






-356

Washington. E. J. Newcomer (September 20): Since the middle of August the number
of moths caught in baits has been considerably less than for the corresponding
period in 1931. The total for the second brood was 8,300 in 1931 and onl-yr 5,600 in 1932. However, the percentage of infestation is about the same as
last year, owing to light crops or, in some cases, less careful methods of
control. The Jonathan crop is reported by horticultural inspectors to average
30 )er cent wormy.

Oregon. D. C. Mote (August): Codling moths are reported in the Willamette Valley.
The peak of egg deposition of the second brood was -reached August 26.

California. H. J. R yan (September 26): A large number of larvae hatched out late
in the season. todling moth control in pears in the Antelope Valley of northern
Los Angeles County was much more satisfactory this season than last as was
evidenced by the number of wormy fruits found by the packing houses this last
month; control in walnuts was also satisfactory. In general pear orchards that
were sprayed at least three times had less than 5 per cent wormy fruit.
S. Lockwood (September 21): The codling moth has either been far more prevalent in pear orchards in the Sacramento delta district this year or control measures
have been less effective, since the:percentage of culled fruits has been much
:reater than heretofore.
FRUIT TRE LEAF ROLLERI (Cacoecia arr-rospila Walk.)

Pennsylvania. J. N. Knull (September 14): During the past season (1932) the
V-marked leaf-roller has been abundant in the northeastern part of P In many places there has been severe injury to the oak foliage.

APPLE SEED C:IALCID (Syntomaspis druparum Boh.) Maine. C. R. Phipps (September 22): The egg punctures are quite numerous in
certain orchards.

County.

Minnesota. A. G. Rug-zles and assistants (September): The apple maggot is veny
a'.ndant in poorly sprayed orchards in Houston County.

APPLE APHID (Aphis pomi DeCG.)

New York. IT. Y. State Agr. Expt. Sta. (September 1): Aphis pomi is vr- abunx'ant
in western New York.

L7AFO.0PP7 -RS (Cicadellidae)
Maine. C. R. Phiops (Septeriber 22): Apple leafhopners are ver- abui..ant in York
and Cuibcrland Cou:tioes.

abundant.

Vermont. H. L. Bailey (September 27): Apple leafhoppers are very abundant at
Top sham.

Connecticut. B. H. Walden (September 24): Apple leafhoppers are very abvndant.
P. Gorman (September 24): The apple leafhopper (Tphlocyba pomaria icA.) is
present in New Haven and Hartford Counties; comercial control is not good.

New York. IT. Y. State Agr. Expt. Sta. (Septem.ber 1): Second-generation apple
leafhoppers are now appearing and are very abundant in western New York.

Kentuciy. M. L. Didlake (August 30): Apple leafhoppers are now abu:iant, although
they were not numerous early in the season.

SAN JOSE SCALE (Aspidiotus perniciosusComst.)

Illinois. M. D. Farrar (September): The San Jose scale is from moderately to very
abundant in central Illinois. Fruit in many districts is shown" lidht scale
populations and there are a few areas where it is heavily infested.

Michigan. R. Hutson (September 26): The San Jose scale is very abun t.

Wisconsin. E. L. Chambers (September 27): The San Jose scale has been becoming
more abundant and new infestations are being found every few weeks but all of them are located in some dozen southeastern counties. The scale has not
as yet gotten into the commercial apple-growing sections.

Colorado. G. M. List (September 20): The San Jose scale has recently been found
to infest several orchards quite heavily in Montezuma County. Previous to this
it was known to exist only in Mesa and Delta Counties and 'has been kept well
undor control in these sections.

PEACH

PEACH BORER (Aegeria exitiosa Sa:)

Connecticut. P. Garnan (September 24): The work: of the peach tree borer is apparent in many orchards in New Haven Cou'nt.

Virginia. H. G. Walker (Septeaber 27): The peach borer is moderately- bundant in
No r fo lk.

Georgia. 0. I. Snapp (September 20): The peak of moth ener-ence occurred in Fort
Valley during the last week-end. Predators--mice or sknts, or both--have
visited practically every peach orchard in this locality during recent months
for pupae and we have found hundreds of empty cocoons near the base of peach trees which these predators have dug out of the ground or tree and eatenthe
pupae. The peach borer infestation should be greatly reduced this -ear on
account of the activity- of these predators.

Alabana. J. M. Robinson (September 22): The peach borer is m.oderatel-- abundant
on peaches.






-358

Mississippi. C. Lyle and assistants ($eptember): The peach borer is reported as
abundant from Monroe, DeSoto, and Lee Counties, and moderately abundant from
the greater part of the State.

ORIE~NTAL FRUIT MOTH (Grapholitha nolesta Busck)

Connecticut. P. Garman (September 24): More abundant in northeastern portion of
the State than elsewhere. New Haven and Fairfield Counties are reported to
have low infestation.

New York. P. J. Parrott (September 22): Moderately to very abundant in western
New York.

Pennsylvania. T. L. Guyton (September 24): The oriental fruit moth is scarce,
about 5 per cent of the fruit being wormy in the Harrisburg district.

Georgia. 0. I. Snapp (Septaember 20): This insect has caused more than usual injury near the city limits of Fort Valley, but as usual there was practically
no fruit infestation in this locality.
C. H. Alden (September 21): The oriental fruit moth is moderately .bundant at
Cornelia. Adults are still being caught in bait traps.

Ohio. T. H. Parks (September 15): The Elborta crop of Ottawa County was harvested
with very little loss from oriental fruit moths. The crop was harvested the
first weeh in September and matured too early to carry many larvae. Elberta,
harvested in Lucas County ten days later, had from 20 to 30 per cent infestation
but without anyr serious loss of fruit.

Illinois. W. P. Flint (September 22): There have been heavy flights of adults
in the southern part of the State.

Kentucky. W. A. Price (September 26): The oriental fruit moth is moderately
abundant.

Kansas. H. B. Hungerford (September): The oriental fruit moth was found for the
first time in eastern Kansas.

Alabac2a. J. IM. Robinson (August): The oriental fruit moth is moderately abundant
in Brewton.

Mississippi. C. Lyle (Se)tember 23): Peach twigs injured by larvae were received during the past month fro; Copiah, George, Jasper, and Jefferson Counties.
Severe injury was reportoc, in some cases.

PLUI: CURCULIO (Conotrachelus nenuphar Bbst.)

Georgia. 0. I. Snapp (September 19): Jarring records show that adults are still
in Fort Valley peach orchards, although the peach harvest has been over for
twro months. The curculio population has increased recentl-y in some orchards
as a result of the late emergence of first-generation adults, and from present
indications more curculios will enter hibernation this fall than a year ago.
First-.;eneration adults deposited a few second-generation eggs during the
latter ,art of Au;ust, but the very small second generation was of little, if
any, economic importance in the Geor cia peach belt this year. On account of







-359

the increa, se in the curculio population, wie antici-pate a heavy infestation in
1933 if there is no more than the USu-al Mortality diurinq- hibernatio-n.



*TARTISHMD PlANT BUG (Lkgns pratensis La.

Washin-ton. E, J. Nexwcoi-.er (.Sep-.tcxcoer 20): 1 an:inatiom -of Bartlett pears i-n an

GRAPE

GRAPE LEAFHOPP.ER (Erythroneura comes Say)

Kentucky. M. L. Didlake (August 30): Leafhoppers on grape caused severe injury,
to point of defoliation, in central and eastern Kentucky.

Utah. G. F. Knowlton (September 13): Grape leafhoppers are causing serious damage
to ornamental Virginia creepers in-many parts of northern Utah. In some cases
the leaves have all fallen from the vines. Serious browning and spotting of
the leaves, with less extensive leaf fall, is common.

California. S. Lockwood (September 21): The grape leafhopper, as last year, has
been responsible for considerable loss to the vineyardists of California from
Sacramento south into Kern County. However, the damage has been more localized
than last -rear and not so severe as the past season except in a few vine-ards.

GRAPE LEAF FOLDER (Desmia funeralis Ebn.)

Kentucky. M. L. Didlake (August 30): The grape leaf folder is abundant in western
Kentucky.

PACIFIC RED SPIDER (Tetranychus pacificus McG.)

California. S. Lockwood (September 21): The spider mite T. pacificus this year
has extended its range on European types of grapes from San Jqaquin and
Stanislaus Counties, where it has been known before, to individual vineyards
in Fresno, Tulare, and Kern Counties, although it may be that some of this
damage in the southern counties has occurred from the feeding of another unknown mite.

PECAN

PECAN LEAF CASE BEARER (Arobasis palliolella lag.)

Georgia. J. B. Gill (September 25): A very heavy infestation of the pecan loaf
case bearer has occurred in many pecan orchards in southern Georgia. The
immature larvae are now going into hibernation by constructing hibernacula on
the buds.

Mississippi. C. Lyle and assistants (September): Leaf case bearers are moderately abundant on pecan at Ocean Springs.

P2CAIT 2:LLOXiRA (P ylloxera devastatrix Perg.)

Mississippi. C. Lyleand ass stants (September): On August 31 a heavy infestation
was observed on a large pecan tree near Utica.

CITRUS

CITRUS MALYBUGS (Pseudococcus spp.)

California. H. J. Ryan (September 26): Citrus mealybugs (Pseudococcus citri Risso)
have been noted from several localities as more prevalent than for several years








also P. maritimus Thrh. and P. adonidumn L. Liberations of Cryptolaemus montrouzi -cri Mull'. were necessary in some parts of Is An-geles Couwnty for
these species. The citrophilus mealybug (P; gahani Green) has been scarce
all season with no damage reported. This is believed entirely due to the
Ausstralian -parasites Coccophag us Trriei Comp. and Tet'racnemas p retiosus Timb.,
sucessfully introduced by the University of California Cit-as Experiment
Station.

BLACK SCALE (Saissetia oleae Bern.)

California. H. J. Ryan (September 26):, The black scale was fully 30 days late
in completing its hatch throughout Los Angeles County. Ordinarily fumiation
can be started in some districts by July 1. This year the delayed hatch
made it necessary to postpone treatment until after August 1. Areas where
work ordinarily begins July 15 were not able to start until ater August 15.


CALIFOPIA R1M SCALE (Chr-somphalus aurantii Mask.)

California. H. J. Ryan (September 26): Infestations are lighter this season
,as compared with the last three years. This is generally thought to be due
to normal cool temperatures last winter which evened the broods so that
control measures this season were more effective than in previous seasons.


COTTONY-CUSHION SRLZE (Icerya purchasi Mask.)

Georgia. J. B. Gill (September 25): Within the past three weeks we have bad
several reports of infestations in various localities in southern Geormia.
Ornamental plants, especially Pittosporum and spiraea, are infested.


CITRUS WHITEFLY (Dialeurodes citri Riley & How.)

Galifornia. H. J. Ryan (September 26): A new infestation was found by' survey
crews in August about 4 miles northeast of the Pasadena infestation found
last surmmer. Infestations were found on two adjoining city blocks. Detailed
survey of the entire Pasadena area has not been completed and it seems probable
that the existing infestations have been limited.

my garden at this lc, but have done no real damage. There may be other
localities infested, but I do not know of them. I first discovered the
caterpillars in a blueberry match in the Wilson Creek Valley, July 10. I
found places untouched by-them and other spots where they were so thick
that I counted from 10 to 20 on a clummo of bushes that I could cover with
my hat. I found no bush that had lost half its leaves. On July 24 I went
over the same section and many berry bushes were completely devoid of
leaves, and cocoons were hanging on bare twigs and stems everywhere. 7illow, particularly mussy willov, is being strioed. In my garden the
caterpillars have slightly infested radishes and turnips, and severely
infested rhubarb grown just outside the garden.

SOUTHERN PINE BEETLE (Dendroctonus frontalis Zimm.)

Southeastern United States. R. A. St. George (September 26): During Se-otember additional outbreaks of the southern pine beetle have reached this office. Upon an investigation a serious infestation was found at Farmington (10 miles west of Winston-Salem), N. C. Several acres of fine
virgin shortleaf nine timber were being killed. The trees would cut
about 30,000 board feet per acre, a very high yield for this locality.
The attack started about July 1 and the brood which emerged continued
to enlarge the infested area. About 200 newly infested trees were found
when the tract was examined Sertember 1. Outbreaks of this beetle during the season 1932 have been reported from the following States: Virginia, North Carolina, South Carolina, Georgia, Florida, Mississippi,
and Arkansas. In general the beetle has been more active in the Piedmont and Coastal Plain regions than has been the case for several years. The
previous outbreaks were confined more to the mountainous and, to a lesser
extent, to the Piedmont regions. The only activity this year noted in
the mountainous area Was within a 25 mile radius of Ashevillo, N. C. A recent reconnaissance study of the Smoky Mountain National Park revealed
no indications of activity this season, quite in contrast to the situation
in 1931.
