TIM I'ORZ IZPOCBTAIT RECORDS FOR SPT2.3TR 1934

Wireworm de.anae, particularly to potatoes, was reported from Wisconsin,
North Dakota, Missouri, and South Carolina.

In this number of the survey bulletin a detailed report is given on the
abundance of the hessian fly throughout the United States. In general this
insect is at a low ebb in the main winter-wheat regions.

Chinch bugs were moving into winter quarters in large numbers through-
out the eastern part of their range. An unusual condition is reported in the
finding of large populations of these insects in Vermont during the latter
part of August.

The corn ear worm was reported as occurring generally from the Gulf re-
gion to Minnesota and from the Atlantic to Utah. In Missouri it is said to
be more prevalent than at any time during the past 30 years, In Colorado corn-
ear infestation was said to be as high as 100 percent. Throughout the greater
part of the country the ear worm was doing serious d-rage.

The fall armyworm was destructively abundant in the Gulf region from
Georgia to Texas.

The codling moth was unuwsially abundant and destructive in the Ohio River
Valley and in the Pacific Northwest.

The Mexican bean beetle was reported for the first time from Orange and
Windsor Counties, Vermont, and from Webster County, Mississippi. Damage has
been general and serious throughout its previous range.

The pea moth (Laspeyresia nigricana Steph.) has been discovered in the
State of Washington, where it occasioned considerable loss in two counties
to growers who were raisi.-.g peas for canning.

The pickle worm again appeared in Connecticut this year. This is its
second appearance in the past 34 years.

K av-y -%. -.re to scgrr beets by the greenhouse leaf tier w.as reported
from Cren: County, Calif. The sugar content of the beets in infested! fields
is so low as to render the. hardly worth harvesting..

The satin moth was reported as occurringC in Oregon, in the Uillanette
Valley. :.is is the first record of the occurrence of this insect in that
State.

One of the elm leaf aphids, --erculatus ulmifolii Monell, was pr.-se.nt
in outbreak .brs in Iowa and ':Tebraska.

Very heavy infestations of crickets in houses located in the vicinity
of public clunms were reported fr.r.- laine, Masr: ch ..-etts, 7'.1 Wisconsin.
In the Massachusetts infestation the insects were so numerous as to force
th'- tenants to leave the houses.

The screw' worm infestation in the Gulf region, from Florida to Texas,
has developed to serious proportions an:'. control campaigns are -*'er wy
over a large part of the territory.

Grasshoppr mig,-ration flights were practically over in Saskatchewan by
the beC'inning of A: o .f.t.. The recorded fli{.hts this ;.-'cc.r 'ere fewer, smaller,
and less far-reaching than in 1933. I:-? Lgeneral, cr..s',c.ppe:rs were notably
less ab-un-.ant than uring the some period last year. Damage to maturing crops
over the infested area, although, serious, was materially li,'ter than in 1933.
As ro-,ght and high temperatures were extrer:.ely favorable to the pest, this
definite decrease in the autumn infestation is attributed to the general success
of the control c :;.:-ai-n. In Manitoba and Alberta warm weather early in Ar, ugst
increased g-ra-shopper ds:..cge and flights, and oats and. barley in certain sec-
tions were injured considerably. Later in the month this 3aice was checked
-y cool weather. Since the middle of Au-gst as.hpper activities nave bee.
largely confined to cgg laying. Throughout Sritish Columbia ,where grashop-
pers have not been abundant for some years, t.-here are evidences of a general
increase that may have serious consequences in interior valleys in 1935.

First-year white grubs are abunda@.t in southern -:.i central Q-e:ec, es-
pecially in old sod, with rubs exceeding 500 per square yard in places.

Reports from Qicbec, Ontario, and Ma.itoba i-.'-icatc that infestation by'
the Colorado potato beetle is about normal.

In souther. Onterio the T .r',-p-,'an corn borer infestation is materially less

Adult moths of the corn ear worm have been reported as far more abundant
than for several years at points in southern Ontario anI s-outherx Qebec.
Heavy, infestations of the larvae also wore noted in sectio:.s of these Provinces
and in southern :,-..itoba, and liLht to od.re local infestations in Sas-
katche'.'o-.- and Alberta.

Heavy local outbrec-'-.s of aphids occurred on crucife.rous crop's in southern
sections of Ontario, Alberta, and Vancouver Island, British Columb-ia. Aphaids
of several species have been extremely abuat on -any kinds of plants in
the Prairie Provinces. Infestation and c!r:: e varied considcraCbly. Th Ie pplc
Lp e orchard i:. certainly sections o s c~
aphid has caused damiace in apple orchards in certain sections of tern
Canada and in British Columbia.

Some losses to -,heat were caused by the wheat stem 'ifly in sections
of the Prairie Provinces. In Saskatchewan these losses apparently were some-
wThat larger than average, particularly in heavy soils of drier areas. In
the Red River Valley, Manitoba, the wheat stem maggrot caused losses ranging
from 5 to 15 percent.

A very general infestation of the corrxon red spider mite in southern
Alberta resulted in considerable dam-age to shade trees, garden truck, and bush
fruits. This species was a serious pest of snuall fruits in Ontario and local-
ly i4. Manitoba. The spruce mite was aE,.Gain very prevalent throuhout the
Prairie Provinces. Mites of several species were troublesome pests of apple,
plum, and pear in parts of the orchard areas of Ontario andC British Columbia.

There has been a general increase in the codlin,- moth infostEtion in
Ontario andl southern Quebec. The species was exceptionally abudant in the
warmer districts of Ontario, where it caused serious damage.

The cray--banded leaf roller is a serious pest in apple orchards of iTova
Scotia.

The oriental fruit moth infestation in the Tiagara Peninsula, Ontario,
was about the same as in 1933. The species survived winter temperatures as
low as 230 below zero.

Grape leifhppers were exceptionally abundant in unsprayed or poorly
sprayed vineyards in southern Ontnrio, where they ca;,Ised much docaf;e.

The outbreak of the 'European n_:.r.c sawfly continues in the Gaspe Peninsula,
Quebec, and the .larvae have defoliated much of the white spruce over a I'arCe
area. Black .pruc- is less heavily infested, but defoliation of this species
also is severe. The a-awvfly has n,.7 been found to be Generally distributed in
New Brunswick, but up to the present dam-age in this Province is not severe.

The hemlock looper has appeared in destructive numbers in parts of Nova
Scotia and on Anticosti Island.

The red-headed pine -a-.'fly is causing serious donage in nyany localities in
Ontario and Quebec.

The satin moth has been reported in the Peace River district of British
Columbia, east of Rolla.

GRAS h ?FZRS (Acrididac)

Michi-:a-.. R. Hutson (September 20): Grasshoppers are v,.ry abundant.

Wisconsin. E. L. Chambers (September 26): A survey of adults just completed
in the northern part if the State indicates, as did the -eg- survey, that
another outbreak of grasshoppers, oven more serious than this years, may
be expected in 1935 if weather is favorable. Eggs are still being laid
and all instars of nymph- arc present in woodlands, cranberry bos, and
roadsides.

Ncrth Dakota. 1. A. '.M'inr- (September 22): F. D. Butcher :'aj's that the grass-
hopper situation this month is characterized by a marked decrease in the
population of Camnula pellucida Scudd. Occasional evidences of paraciti-
zation by Diptera were noticed in the field. In most areas .Tclan. 1os
mexicanus Sauss. is the predominating species. Adults of M. differonti-
alis Thos. were observed in Mercer, Oliver, and Morton Counties on Septem-
ber 20 and 21.

Missouri. L. Hasoman (September 24): In central Missouri red-legged grass-
hoppers are fairly common but are doing no d:ajei.j.

Arhs.u:,. D. Isoly (September 24): Grasshoppers (LM. differentialis) are
very abundant.

Nebraska. M. H. Swcnk (September 20): Gras-'hrpors are mr-irately abundant.

Kansas. H. R. Bryson (September 26): The gras-.hnpper population is bolrw
normal for this time of year. M. differentialis individuals are more
difficult to find at Manhattan than for several years past. A re-ort of
injury to young alfalfa during th- past month was received from zS'ihie.

Colorado. G. M. List (September 20): Gras.sh-ppcrs, since the clo-,ing of
the poisoning c:mpaiga, are only mod-:ratcly abundant.

0. G. Babcock (August 27): Grasshoppers (M. bivittatus ay) are
very numerous on farms between Denver and Fort Collins and Greeley.
Thousands of inland g.alls are feeding on the hoppers.

Arizona. C. D. Lebcrt (September 19): Several fields in the Salt River Val-
ley still have mci.rate inAfcstations of hr-ppcrs, both M. mexicanus and
M. differentials. Ycung hoppers of the third a-nd fourth instars are
still present. ,cttuce gr,-.'ers are applying poisoned-bran b-&its.

the Arkansas line. Some complaints have come from north of the Missouri River,
especially from Montgomery Coun.ty.

WHITE-LIiED SPHIIF: (Sphinx lineata Fab.)

Oklahoma. C. F. Stiles (September 24): Russian-thistlcs throughout the wes-
tern part of Oklahoma, and especially the Panhandle area., are being at-
tacked.. The armyworrms migrate across the wheat fields, defoliating the
thistles, but have not damaged the wheat or any of the grass plants. On
September 10 they were migrating by thousands from one field to another
in Harper and Cimarron Counties.

WHITE GRUBS (Phyllophaga spp.)

Maryland. E. N. Cory (September 26): White grubs, probably P. hirticula Knoch,
are very abundant in Ellicott City, where they have destroyed 5" percent
of the corn.

Michigan. R. Hutson (September 20): White grubs are very abundant.

GREE1N JUNME BEETLE (Cotinis nitida L.

Indiana. J. J. Davis (October 2): Grubs were reported as abundant in and
destructive to lawns at Terre Haute on August 29. During September several
correspondents sent in the grub parasite Scolia dubia Say which indicates
an abundance of the parasite.

Kentucky. W. A. Price (September 25): Green June beetle larvae have been very
abundant in many lawns at Lexington, Winchester, and Versailles.

DEE7.RT JUTJ'E BEETLE (Ochrosidia villosa Burm.)

California. C. S. Morley (September 1): A serious infestation of larvae, which
completely destroyed the lawns in a cemetery at Bakersfield, was observed.

JAPAKESE BEETLE (Popillia japonica iTewm.)

Eastern United States. C. H. Hadley (August): All sections except the extreme
northern part of '71w Jersey are now in the area of continuous distributiAn.
There are increases in lower Cumberland and throughout Cape :"a.7 County.
The area of continuous infestation in Pennsylvania is approximately indi-
cated by such localities as Easton, Allentown, Reading, Honey Brook, Chris-
tina, and Oxford. In Delaware infestation extends across the State north
#f Middletown, and farther south extends west to Van:Ldyk,; and Kbnton and
south to Woodside, Magnolia, and Bowers Beach. An increase is noted in
all infested sections. In Maryland the area of continuous infestation cen-
ters at Elkton and has increased. All Staten Island and the extreme
eastern part of Long Island are now included in the area of continuous in-
festationin New York.

7eostchoster Coi.-ty,-, N.Y., .. sho'vn some i.-cr, Z.co in 193. T. beetles
were recorded at- Valhalla this sirnmer for the first time, '.'-:y had previ-
ously booeen found in the northern part of the cc..ty at Os-i.i-g, Peeks-
kill, Mount Kisco, and AmaWalk. T.e beetles are ge:-.:.ralCly distributed in
W.7 stchester Cou.nty, although they are much more scattered in the northern
part. However, fewer complaints of Ljury by' the adilt beetles were re-
ceivw:d from this county than in 1934, bcs during the son o actual
flight in 1934 there were fewer hot .:-i, '_hts than normal, re...JtinC; in less
feedi-' in gardens. Bronx:c County shows little ch'.nge in abundance. Kin-s
County show's an increase throughout. i'.sau County shows some increase,
especially in the western half. In northeastern 1-w Jersey the beetle
-h. s increased abundance in the open country. Adults were found at Bound
Brook, X.J. in August 1934 for the first time, Observations during the
past 7 years indicate that increased losses will probably be caused should
it occur farther south, provided there is sufficient rainfall for normal
development of the immature stages.

WIREWORI.:s (Elateridae)

South Carolina. C. 0. Bari, (August 21): A survey of vegp table planti'.ins at
the South Carolina Truck Experiment Station at Charleston showed consider-
able injury by wireworms. Counts of the injured plants of each crop made
on two 4r0-foot rows gave the followin.c Cucumbers, 94 out of 753, or
12 percent; cantaloups, 34 out of 1,273, nr 3 percent; :-q-ash, 1 out of
723, or 0.13 percent; cabbage, 2 out of 2,95C, or 0.06 percent. en"ir per-
cent of the 240 cucumber hills in the t..', rows were destroy.ii.

Wisconsin. E. L. Chambers (September 26): Potatoes on low h avy soils with
little drainage are being seriously injured by wircworms in Racine, Xil-
vaukce, and Waukesha Counties, atcord.ing to potato dealers.

North Dakota., J. A. Mu-iro (September 24): A 20-acre plot of potatoes in the
vicinity of Saint T.-.':.ac is reported as badly i- tested. In 19"2 ..*r,; thcn
30 percent of the potatoes from this plot were urnarketable,on account of
:uireworm injury; in'-1933 from 15 to 20 percent rcre unmarketable; and
this year -virev.orm injury has re .1 r..'l 75 percent u-'it for :.:"t.

Miss ri. L. Hasan. (September 24): At Colunbia during the early part of
September ,.'ireworms-were severe on late *.:.-.t"corn. Larvae are about
half r ...

CC.:...: F, _D SPIDER (t, t:" .e:- t7-lrius L .)

CoGlor.. G. M. Lis.t (Spt'- mber 20): i:. dry season hlias favored the crnr.on
red .rider, which is qlite inj ..'ious on a numbsr of trees ani -hrbs.
In some instances it has d h field cr-s as :cas .. corn.

Califor. iia. C. 5. Morley (cept ember I): -.is. has bceni one of the worst







-251-


seasons ever experienced for red spiders, and the damage was intensified by
lack of irrigation. Bakersfield has completed the .pr rying of 23,051 shade
trees.

WHEAT

HES3IA;T FLY (Phytophaga destructor Say)

General. P. N. Annand (September IS): The hessiani fly is in general at a
low ebb in the main winter-wheat regions. Drought has largely kept this
insect in check. Areas in which scattered fields suffered more or less
injury this year are southeastern Kansas, southern Missouri, east-central
Indiana, middle Tennessee, northern Ohio, south-central Pcn : sylvania,
and central ITorth Carolina. With weather conditions favorable to the fly,
moderate to severe infestations :-r" develop this fall in these areas.
In the remainder of the winter-wheat belt, comprising ITebraska, northern
and middle Kansas, northern _issoori, all of Illinois, western and south-
eastern India.na, southern Ohio, western, northern, and eastern Pennsyl-
v7Lnia, Maryland, Delaware, and Virginia, there appears to be little pros-
pect of serious general infestation this fall.

than usual numbers on volunteer


Larv:.c andl pup- ria are present in more
wheat. We look for a heavy fall emer-


.*,-nce and infestation of early sor-:d ",-at in the northern half of the
State.

Missouri. L. Has san (September 24):, -arlier observations i...ic.te that
the heat of midsummer proved very destructive to flaxsceds.

SAY'S ST IT BUG :(Chlorochroa _.. Stahl)

Colorado. G. M. List (September 20): Say's stink bug has been quite numer-
ous during much of the season. Barley a..i wnt,-at were injured cr*-sider-
ably just at filli-. time in the. Pueblo a 1.1 E1 Paso County sections.
In Pueblo and Denver vicinities the bu,-s dawia,y:,,d truck crops and, in a
few instances, sugar beets. Fear Denver one -ar-'c.-.r lost almost his
entire crop of "rden beets and a 3-acre field of early cabba,j:.

0ORN

CHI'CH 3U3 (Blissus leucopterus Say)

Vermont. H. L. Bailey (A:Ljust 29): :IntenAive infestations were f-'-Lid in
millet at Mi' A.esex, in 7a'..-ington Counity, on AKLjst 20, and at Brain-
tree, Orenge County, in corn on Au>-ist 23.








-253-


Ohio. T. H. Parks (September 25): A fall survey now being conducted reveals
that chinch bugs are much more abundant than last fall and late sweet corn
is badly infested. Complaints are being received from counties south of
the area where injury occurred in June and July.

Indiana. J. J. Davis (October 2): The chinch bug situation is serious. Re-
cent surveys iJdicate a greater abundance and wider distribution than a
year ago.

Illinois." W. P. Flint (September 20): The wet weather late in August and
early in September has had a somewhat detrimental effect on chinch bugs.
The white-fungus disease v.s been very abunio:.t and has killed a consider-
able number of bugs. However, nearly as many bugs will go into winter
quarters as did so in the fall of 1933. Many bugs are already in hiber-
nation at Urbana.

Kentucky. W. A. Price (September 25): Chinch bugs are very abundant.

Missouri. L. Haseman (September 24): Recent observations indicate that the
chinch bug is very abundant only in scattered fields. It is less abundant
than we expected.

Nebraska. M. H. Swenik (September 20): The chinch bug is moderately abundant.

Kansas. H. R. Bryson (September.26): Chinch bugs are moderately abundant at
Manhattan and in the eastern part of th1e State. The adults may be easily
found in crabgrass and other wild grasses along roadsides, fence rows, and
in fields. The population is below the usual number.

CORN LARTTER1T FLY (Peregrinus maidis A-Jr:. )

Mississippi. C. Lyle (September 19): Medium damagEc to corn was reported from
Aberdeen, in Monroe County, on September 4, and specimens were sent in on
September 1I from Jackson, in Hinds County, with a report that the insect
was abundant on pop corn.

CORIN EAR "'7RM (Heliothis obsoleta Fab.)

North Carolin:a. W. A. Thomas (September 8): Late corn following potatoes in
this section (Stonewall) has been almost destroyed. Stalk, foliage, tassel,
and ear have been attacked. Sone of the growers are much concerned, as
this is the Gource of grain for most of their farm animals. The growers
estimate that the yield will range from nothing to 4 barrels per acre;
20 barrels per acre being about the normal yield. on these la:.es.

South Carolina. F. Sherman (September 19): The corn ear worm is very abundant
on corn but nearby tomato fruits show little if any infestation.

Ohio. T. H. Parks (September 25): The corn ear worm is very abundant on sweet
and field corn. The infestation follows one of the most severe winters
on record, with February temperatures dropping to 15 to 20 below zero in
northern Ohio where worms are now abundant. This supports the theory that









-254-


these moths migrate long distances.

Ohio. .. F. Howard (September 22): Late sweet corn in the vicinity of Colum-
bus is very heavily infested. Every ear ex&-i.-:d had 1 or 2 worrs on the
tip. an in.ch or two of which had bee destroyed, as well as 1 w orm lower
down w-iLch had entered through the husks on the side. Considering the
unsightlin.ess of the ears, it is believed that most of the corn in the
fields wo.s unmnarketable. I have received report that the insect is very
injurious to chrysanthemums and tomatoes in a cree.-'house in the vicinity
of Dayton.

Indiana. J. J. Davis (October 2): The corn ear worn is more abundant through-
out the State then it has been for a number of yc-rs. It is heavily in-
festing corn and tomatoes. One report of abunic-.nce in soybeans was re-
ceived.

Illinois. W. P. Flint (September): The corn ear worm is more abundant than it
has been at any time during; the past 5 years. It has very serio-,sly
da.-ig'-d field corn, destroyi:;; probably 7 or S percent of the kernels on
most of the ears. It is also feeding; extensively on the foliage of late
soybeans and on the pods of late beans.

Kent'cl/r. W. A. Price (Septermber 25): The corn ear worm continues to be very
destructive to tomatoes, beans, and alfalfa.

Michig-an. R. Hutson (Septemb.-r 20): The corn ear worm is moderately abundan.t.

Wisconsin. E. L. Chambers (Septe:ber 26): The second and possibly a third
brood of the corn ear worm attacked both sweet and field corn. This is
the worst infestation ever recorded in Wisconsin. In some fielIs the in-
festation is 50 percent in field corn and. even hi-her in S?"-7,t corn.

Miniesota. A. G. RuCgles and C. E. Mickel (September 25): The corn ear worn
is very abu,-ad-it on very late sweet corn in parts of th.. State. Adults
were flying on September 7.

Missouri. L. Haseman (September 24): The corn ear worm outbreak is the worst
in 30 years. Late broods are v.ry large. Owin-, to shortage of corn ears
the worms are turninZ to alfalfa and soybeans, doing- serious da..:aCe to
these crops over .much of the State.

Nebraska. M. H. Swenk (September 20): The corn ear worm is very ab'undant.

Mississippi. C. Lyle and assistants (September): The cornl ear worm is very
abundant on corn and tomatoes in La'.i-L-rale, Bolivar, Lowndes, and M.onroe
Counties.

Co1,,''r.-,. G. [. List (S.:ptember 20): The corn ear worm has been unusually
numerous in all sections where corn is ;rown. The i:i'-fe station in most
localities will be 100 percent. Tl.e first broo'. attacked the tassels of
the early sweet corn, much of 'vhich was so seriously injured that it was
cut and fed to livestock.











-255-


Utah. G. F. Knowlton (September g): Corn car --!orns are damaging from 3 to
55 percent of the tomato fruits in fields in Davis and Weber Counties.
The high infestation is slowing; do,-n can: ing operations in factories
throughout Utah.

BUJ. BL7 FLC"T- BEETLE (Euphoria inda L.)

Colorado. G. M. List (September 20): The brimble flower beetle has been re-
ported from a number of localities as injuring corn by feedinC on the tips
of the ears.

ALFALFA

ALFALFA WEEVIL (Hypora postica Gyll.)

California. A. E. Michelbac.cher (September 22): The alfalfa weevil is rather
abundant in some fields around Niles and Pleasaniton. On July 23 a single
dipterous internal parasite of the larva vas found at lTiles. No further
search was made for this parasite until Septe.i'mber 14, w-hen weevil larvae
were brouj-ht into the laboratory. About 10 percent of those large enouCi
to spin cocoons were infested. With the parasite. As yet the parasite has
not been reared, althoug-h a number are leaving the parasitized larvae and
are pupatinC.

GARZCUII ,7 E.30R.i (Loxostogo similalis Guen. )

Ohio. T. H. Perks (Septeriier 25): Larvae of the alfalfa webworm, together
with injured alfalfa foliage, were received with the statement that they
were severely injurin- alfalfa in several fields in Greene County.

Indiana. J. J. Davis (October 2): The garien wvebworm was reported damaging
alfalfa at Portland-. on Ia-ust 24.

Illinois. V. P. Flint (September): D-ring the latter part of Au-ust the al-
falfa ;.rebworm w.as extremely iestr'-ctive throughout the State. It has been
much less abun-dant during Septorpber.

Missouri. L. Hasenan (September 24): The l-te brood of the alfalfa webworm
has dne a good- deal of d-mage to the last cutting of alfalfa in central
Missori. Moths are on the wing in, moderate numbers.

YELLOi-3TiTRIPZD ARMY*TUO.L (Prodenia ornithogalli Guen.)

Illinois. W. P. Flint (September): The yellow-striped armyworm has been very
abundant and- destructive over most of the State during the past month.
The principal injury has been to newly sown alfalfa. It has also damaged
soybeans and some truck crops considerably. Parasitization has been
rather low.









-256-


BEAN THRIPS (Heliothrips fasciatus Perc.)

California. A. E. Michelbacher (Septer:ber 22): On Septemb-er 7 the bean- thrips
was present in countless nunIbers in thle alfalfa fields about Vernalis.
A week later they were still very ab:. :.nt but much reduced in numbers.
A similar condition was noted a year ajo.

SOYBEAITS AID VELVETBEA'TS

FALL ARMYWOiM (Laphyrma frucwiperda S. and A.)

Georgia. 0. I. Snapp (September 22): The fall armyworm destroyed 25 acres
of soybeans at Fort Valley.

Florila. J. R. 77-.tson (September 24): Th.- fall armyworm stripped the cover
crops from many jroves in Lake and- Polk Counties in the early -art of the
month.

Arkansas. D. Isely (September 24): An outbreak of the fall armyworm has been
reported from Marion, Johnson, and ashin-ton Counties.

Mississippi. C. Lyle (Septcrher 19): A very light infest,.tion on pop corn
was reported from Jackson, in Hinds CoLu.t-, on September IS.

Texas. F. L. Thomas (September 16): Millions of tiny worms streamr:ing across
the tracks were able to stall a ponderous freight train near Estelline,
in Hall County. They were also very abundant at Crystal City, Zavala County

S. E. Jones (September 7): In Crystal City fall arr.',7orms are causing
much damage to hejari.

VELVEBT? C.ATT-PILLR (Anticarsia rcn.:.atilij Hbn.)

Florida. J. R. Watson (September 24): T'.e velvetbean caterpillar has thoroagh,-
ly ragged most velvet';-an fields in Florida.

Louisiana. W. E. Hinds (Aiit 29): Soyt-an caterpillars have been seen only
in a few instances and then not in niu.bers to strip the folia-e, even on
their favorite .'vrieties. iT serious damage is expected. Some stripping
started at Jeanerette about August 15, also around :T-.: Iberia. No cgs
were found at that time.

GREFZ[ CLOVW 170RM (Plathypena scabra Fab.)

Yorth Carolina. W. A. Thrr.-.-, (.^ptember 22): A li,`ht infestation -,os obs'-rved
in soybeans in Pamlico anl Columbus Counties on September S. "o appreci-
able d.-.i;:, -*.*"s bein; done. Specimens of this insect and what appeared.
to be the fall arfy.cr (La ;j fri i S. and A.) are associated in
defoliatingu soybeans r"'n for seed.

South Carolina. W. C. Nettles (Septemiber 19): The Green cl.-v.r worn is re-
ported to be defoliating; soybeans in at least one locality in the eastern
part of Dorchester County.










FRU IT INSECTS


APPLE

CODLING 2 OTH (Carpocapsa pomonella L.)

South Carolina. 0. L. Cartwright (September 19): Injury to apples by
the third brood is very prevalent at Clemson College.

Ohio. T. H. Parks (Sentember 25): The codling moth is very serious
again in Lawrence County, in southern Ohio. Seven cover sprays have
failed to control it; and worm entrances were abundant during August
and September owing to a rather heavy third brood of larvae. Else-
where in the State the insect is not so numerous but populations are
increasing, even where extra early sprays had been applied.

Kentucky. W. A. Price (September 25): The codling moth is very abundant.

Michigan. R. Hutson (September 20): The codling moth is moderately abun-
dant.

Missouri. L. Haseman (September 24): Late worms are scattered over the
entire State. A few moths are still emerging and young worms are
entering fruit. Loss abundant than for several years.

Nebraska. M. H. Swenk (September 20): The codling moth is moderately
abundant.

Kansas. H. R. Bryson (September 26): On August 28 workers in north-
eastern Ktzsas reported an overlapping of second-brood and third-
brood moths. Moths were abundant but dre'-,:o was comparatively light.

Texas. W. L. Owen (September 8): Fewer wormy apples than ever before
are reported from the vicinity of Fort Davis. The owner of a large
commercial orchard estimates that not more than one apple in 500 is
infested.

Washington. E. J. Newcomer (September 21): Continued hot weather up to
September 6, together with the early season, resulted in an unusually
large third brood in Yakima Valley. The peak of this brood came the
last week of August, and bo-rn to decline noticeably early in Septem-
ber, although the vicather remained hot. This caused a heavy attack
by late worms, which in many cases more than offset the eorlior light
infestation. Some orchards were sprayed 10 or 12 times during the
season.

FLAT-T3ADED APPLE TREE EORER (Chrysobothris femorata Oliv.)

Indiana. J. J. Davis (October 2): The flat-headed borer has been un-
usually abundant in and destructive to apple and maple, especially
aople, in the northern half of the State.










Nebraska. M. H. Swenk (September 20): The flat-headed apple tree borer
has been abundant in young apple trees in Fillmore County.

PEACH

CRI-.TTAL FRUIT MOTH (G-rayholitha molesta Busck)

Connecticut. P. Garman (September 24): In New Haven County larvae re-
mained in peach twigs until late and will hibernate without entering
fruit. There is some increase in infestation in apples and quinces
this year, but it has not been particularly marked.

South Carolina. 0. L. Cartwright (Septnmber 19): Adults are being taken
in bait pans in apple orchards at Clemson College. Peach fruits are
gone.

Georgia. 0. I. Snapp (Sentember 20): Some larvae have already entered
hibernation in Fort Valley.

Ohio. T. H. Parks (September 25): Injury from larvae in peaches and
quinces is much less severe than during former years.

PEACH BOPRER (Acgri% exitiosa Say)

Georgia. 0. I. Snapp (September 20): The peak of moth emergence in Fort
Valley occurred on September 16, which is about normal. The infesta-
tion is of aver -ie intensity. The dipterous parasite Anthrax lateralis
Say is beginning to emerge.

PLUM CURCULIO (Conotrachelus nenu1rh-.r Hbst.)

Georgia. 0. I. Snapp (September 20): Some growers in Fort Valley have
-de after-harvest applications of arsenical dust to reduce the number
of adults before they enter hibernation. The infestation is rhevier
than that of nn average year. The dipterous parasite .':;,ioph-sia
globosa Towns. vw-s fairly abund-nt this year, many adults being on
wing about Aunust 27.

SAN JOSE SCALE (..,iu p.riicio,,u Comst.)

Georgia. 0. I. Snapp (September 20): The San Jose scale increased rapidly
on peciho trees in Fort Valle.' during Scpttmter. The infestation is
now fairly he-wyv in a number of orchards. A summer application of oil
emulsion has been u'-ite in several orchards to hold the scale in check
until the dormant spr-nyin season.



GRAPE LEAFHOPi-ER (Ery'th"r:neru cor7s S-:.')

ebr,,c-. M. H. Swenk (Sept-'rbr 21): Reports of attack by the grapec











-259-


leafhopper on grape and woodbine vines continued to be received up to
September 1.

Colorado. G. M. List (September 20): The grape leafhopper has been very
abundant on grape and woodbine. Many of the latter, where grown for
ornamental purposes, are nearly defoliIted.

RED-PAnED THRIPS (Solenothrips rubrocinctus Giard)

Florida. J. R. Watson (Sertember 24): Grapes that had been severely at-
tacked by the r3d-banded thrips were received from West Palm Beach.
The thrips caused a russeting of the rind very similar to their work
on guavas.

?FCA

FALL ,.EB'>70RM, (HyT)hantria cunea Drury)

North and South Carolina. W. A. Thomas (September 15): The second genera-
tion is much more numerous along the Coastal Plain on pecan, persim-
mon, and forest trees than at any time during the past 10 years. Hard-
ly a pecan tree has escaped injury, and many are already completely
defoliated. In some instances, the green husks on the nuts have been
partly eaten off.

Mississippi. D. W. Grimes (September 20): Fall webworms are general
around Durant, where the injury to pecan rar-ifs from moderate to
severe.

Louisiana. T. E. Snyder (Seoptember 7): The fall webworm is ouite abundant
on persimmon trees between New Orleans and Alexandria.

PECA!T WEEVIL (Curculio caryae Horn)

Georgia. T. L. Bissell (September 2b): The pecan weevil began laying eggs
about September 2 at Milner, and small numbers were still active on
September 25. Weevils have been more abundant than in any year since
1930.

CITRUS

GREEI CITRUS APHID (jAhis spiraecola Patch)
Puerto Rico. G. V. Wolcott (August 13): Citrcs shoots. the leaves of
which have been curled by the green citrus aphid, were collected yester-
day near Comerio. This insect seems to be increasingly common and its
injury is noted widely, not only in the recognized citrus districts,
but also, as in the present instance, miles from the nearest known com-
mercial grove.












CITRUS '.-ITEFLY (Dialeurodes citri Riley and How.)


Florida. J. R. Watson (September 24): The citrus whitefly is very abun-
dant. Hevy fli-:'t of adults now noted in northern Florida.

Georgia. 0. I. Snapp (September 20): As usual, this insect is very abun-
dant in Fort Valley and is causing considerablee d.Tma-e to orrrnmental
plants.

Alabama. J. M. PRobinson (September 21): The whitefly is more ncunint
over the State than it has been in years. The general infestation
-ight be called -in outbrc'k.

Mississipp:i. G. L. Bond (September 18): Moderately abundant in Jackson
County. A few eL.f'v infcsttions h'.ve been noticed recently and the
whitefly is pr .sent on most citrus hedge plants.

COTTONY-C'-ISIC,' SCALE (Iccrya purchasi Mask.)

Puerto Rico. G. N. Wolcott (Septnmbe r 20): Since the initial outbreak of
the cottony-cushion scale in San Juan and the Ba,'r-m-. citrus district
in 1932, no new records of its divrsion in Puerto Rico had been re-
ceived up to a few weeks ago. Late this spring ane new occurrence
was noted near Vega -Baj, and more recently another h-s been r:'pcrted
at some distance from the first, both of these prcs..7-.bly being due
to n'atura-l dispersion, as they are west or southwest of the main areas
of infestation. WVithin the last few days the scale has been reported
in a small grove at HTumacao, in the cO.storn p-.rt of the Island, un-
doubtedly duo to the bringing in of infested trees Land rot to natural
factors. In the main arc-s of infestation the scale has not been
abundant this spring and a survey made on SeptLmo.jr 18 indicated that
it was very scarce generally. In one instance, an infestation has
entirely disappeared, and in most inst-iIccs only a few scattered in-
dividuals can be found. Wherever sm..ll mass infestations still exist,
one can find traces of the Austr'-lian ladybeetle (Bodolia cardin'.lis
Muls.), and because of recent rainy weather over half of the scales
have been killed by the fun/uas Spicrrig .j:.v'-.ic.

FULLEr'S ROSE 3EETL7 (Asynonychus l, i Crotch)

Al.bml. H. P. Lodin' (Septeorbcr 28): Fuller's rose beetles are becoming
increasingly abundant in Satsuma or:--.:. groves .t Mobile, where they
are damin'.g the foli,'e.

CITRUS R'JST MITE (.hylloccptes olcivorus As-.m.)

Florida. J. R. Watson (September 24): Dry v.'-,thor duri-.- the last few
days of Ap ust nnd the first 'f Seo.tember nued an increased number
of rust mites in the or'-j- ,-*revcr, for this time of the y,-r.











FIG ..


THREE-LITED FIG PORER,(Ptychodcs trilineatus L.)

Alabama. H. P. Loding (Seotember 28): Many old fig trees in Mobile have
been killed this year by the l-rvae. The infestation is general.

Louisiana. W. E. Hinds (August 29): The fig borer has caused a number
of complaints, especially in the area about Opelousas. Laorvae of
all sizes are working in the branches.

COCONUT

A HHITOCEROS BEETLE (Stre.tegus quadrifoveatus Beauv.)

Puerto Rico. G. N. Wolcott (September 11): Within the l-st few weeks
three complaints of d-.-a-e to palm trees caused by this beetle have
been received, two from the coast, Loiza and Quebradillas, and one
from the mountains, at Aibonito, where ornamental palms were attacked.
Presi--:ibly this is one result of the hurricane of San Ciprian 2
years ago, for the coconut palms destroyed at that time (in some in-
stances 90 percent of the trees in extensive groves) require almost
a year before becoming sufficiently rotten to furnish suitable food
for the immature stages of the beetles, and the development of the
grubs requires another year, which brings an outbreak of the beetles
2 years after the hurricane.


TRUCK -CROP INSECTS

BLISTER BEETLES (MWloidae)

Kentucky. 1'%. A. Price (September 25): Blister beetles are co-mon and
destructive generally ov:r the St:ate, feeding on late potatoes, cab-
bage,. tomatoes, and dahlias.

North Dakota. *J. A. Munro (Septeambcr 22): The State Forester reported
that Chinese elm trees in New Salem were defoliated by the ash-gray
blister beetle (Macrobasis unicolor Kby.) during the past season.

F. D. Butcher observed this blister beetle attackin-t> Chinese
elm at Dickinson in 1933.

....... FALSE CHINCH BUG (Nysius ericae Schill.)

Wisconsin. E. L. Charbers (Srepteber 26): The f-ilse chinch bux- has been
unusually abundant in the southern half of the Stato this summer and
has b.en dsamaging strawberries.








-262-


POTATO A'TD TOMATO

A PYRALID (P-?hyzancla periusalis Walk'.)

Georg-ia. T. L. Fissell (September 1): Larvae ha're been noted, since
July 27 at the Georgia Exreriment Station on tom-to plants growing
thickly in pots in the greenhouse and just outside. By A,_i'rst 16
they had spread to tomato plants in an open hotbed, Today I found
a few larvae on a tomato plnnt in the garden near the greenhouse.
EBgplants in this garden and in a distant field are he-vily in-
fested. Tomr'toes in this field are free. A few larvae were ob-
served on horsenettle near eggplants.

A MIRID (Engytatus cniculatus Rcut.)

California. H. J. Ryan (Augist 30): A plant bug identified as E.
geniculatus was found att7,c',:ing tomato plants on several proper-
ties in the San Fernando Valley. This was first taken in southern
California in Orange County in 1931.

LEAF-FOOTED BUG (Lcotoglossus phyllonus L.)

YTorth Carolina. W. A. Thomas (September 15): The nymphs are very abun-
dant on potato and tomato in some fields near Chadbourn. When large
numbers attack a potato stalk they cause it to wilt down in one day.
The tops of some plants hv:) already been killed.

Georgia. T. L. Bissell (Seictomber 26): This bug is slightly more abun-
dant this summer than usual at Experiment. Adults and young have
been found on elderberry, cotton, Cophal',-thus, cowpLas, -id jimson-
wecd. L. oppositus Say also was observed on cowpeas.

TOI'ATO PSYLLID (Paro trioza cock:relli Sulc.)

Utah. G. F. Knowlton (September 5): Pototo psyllids have been abundant
enough to cause damage in some fields in various parts of northern
Utah.

Colorado. G. M. List (September 20): The tomato ps',llid has been moder-
ately abiind ant on potatoes and tomatoes in a number of localities.
In Mesa County, v"here the injury to early notit'ies is usually quite
severe, the infestation was not as heavy as. during the past two
seasons. Untreated early -oetatoes in Weld and M.rgan Counties suf-
fered a loss of probably 20 percent. Late potatoes in these sections
are showing some injury, and there will be some loss in a number of
other localities. The infestation on tma.tocs in northern Colorido
has been rather severe, the crop being materially reduced and the
quality -mich, lowered.











BE AIS

MEXICAN EAIT BEETLE (EpIlachna corpta Muls.)

Vermont. H. L. Bailey (August 29): Mexican bean beetle moderately abun-
dant. Reported for the first time in Orange and Windsor Counties.

Ohio. T. H. Parks (September 29): Injury has been very severe in many
localities, including the lakeshore area.

Indiana. J. J. Davis (October 2): The Mexican bean beetle was abundant
on beans at Indianapolis and Merom early in September. About the
middle of September we observed soybeans near G-recncastle heavily in-
fested and there wore no garden beans nearby.

Illinois. W. P. Flint (September): The Mexican bean-beetle has been
more abundant throughout the east-central part of the St ate than in
1933.

Alabama. J. M. Robinson (September 21): Mexican bean beetles have been
very abundant at Auburn and in the central and northern prrts of the
State throughout the season.

Mississippi. C. Lyle and as-istants (September 19): Specimens of the
Mexican bean beetle wore sent -to this office on August 24 from
Webster County for the first time. They were reported as seriously
injuring garden beans. The beetle has also been reported as very
abundant in the eastern half of Lowndes and Monroe Counties and at
Hattiesburg, in Forrest County.

BAITDED CJCL"rTER BEETLE (Diabrotica b-lteata Lee.)

Alabsamna. J. M. Robinson (September 21): The banded bean beetle is more
abundant in central and southern Alabama than it has been during the
past 6 years.

PEAS

PEA MOTH (Laspeyresia nigricana Steph.)

Washington. D. J. Caffrey (September 29): Specimens of leridopterous
larvae were collected on July 14 by J. .7 Stanton, of Bellingham,
who states that this insect has caused the farmers of the Bellingham
district and Skagit County a considerable loss this year in peas
grown for canning. (Det. by C. Heinrich)

S CABBAGE

IMPORTED CABBAGE E'ORM (Ascia r,-.rae L.)
Ohio. T. H. Parks (September 25)' Larvae of the imported cabbage worm
have seriously injured cabbage.


-263-











Wisconsin. E. L. Ch-mbers (September 26): More dn-r,' e from cabbage worms
has been experienced in the southeastern part of the State this fall
th-In for many years. Many fields were injured so severely that they
could not meet standard market requirements in Dane County.

CABBAGE WEBWORMI (Hollula undalis Fab.)

North Carolina. W. A. Thomas (September 20): The cabbage webworm is
still one of the principal limiting factors in obtaining a stand of col-
lards and related plants in the Chadbourn area at this season of the
year. On larger plants the larvae bore into the stalks and leaf .
petioles, causing the buds to die and weakening the leaf stems, causing
them to break off.

CROSS-STRIPED CABBAGE WORM (Evergestis rimosalis Guen.)

North Carolina. W. A. Thomas (September): Larvae of the cross-striped
cabbage worm are mach more numerous on collards in the Ch-idbourn dis-
trict this year than usual. Ordinarily an occasional specimen is
seen, but this season they are almost as abundant in some fields as
is the common cabbage worm.

CABBAGE LOOPER (Autographa brassicao Riley)

Missouri. L. Haseman (September 24): Cabbage loopers are more abundant
rnd more destructive to late cabbage than I have ever seen them.

HARLEQUIN 3UG (Nurg-i.nt i- histrionic Hahn)

North Carolina. W. A. Thorns (September 20): The h-rlequin cabbage bug
continues to be a rnn.or pest of collards in home gardens of the Chad-
bourn area. In some gardens most of this crop has alro'-ay been killed.

Iowa. H. E. Jaques (September 22): The harlequin bug is mking its first
apneor-a-nce for the season in southeastern Iowa. Occasional specimens
have been taken.

Kansas. H. R. Bryson (August 28): The harlequin bug is reported to be
quite abundant on r.:mna-it cabbage plants in gardens in northeastern
Kansas. These :'.s were observed feeding on turr.nip at Manhattan.

California. D. J. Caffrey (October 4): Living specimens of the harlequin
bug were received from Decoto, Alameda County, where the insect was
seriously dna.-.in- turnips and squash.

MELONS

FICKLE WORM (Diaphania nitidalis Stoll.)

Connecticut. V.. E. Britton (September 24): Larvae were received from
Guilford on Sonptc-mbor 5, in sammrr crookneck squash. In 1931 this








-265-


insect occurred at several points in Connecticut near the coast. In
the past 34 years 1931 and 1934 have been the only two seasons when
the insect has been observed by members of the staff or brought to the
attention of the entomology department.

South Carolina. W. J. Reid, Jr. (September 24): D. hiyalinata L. and D.
nitidalis are as usual very destructive to fall plantings of cucurbits
in the Charleston area. As a result, local growers have practically
discontinued attempts to grow cucurbits during the fall months. Larvae
of both s-ecies were first observed this season feeding in small num-
bers on the remains of a spring crop of squash on July 10. No signs
of the insects had been noted on this planting earlier. They had
appeared in an experimental fall planting of cucurbits at the South
Carolina Truck Experiment Station on September 7, 10 days after the
plants came up. At that time, 29 percent of an acre planting of
squash, 8 percent of a half-acre planting of cucumbers, and 2 percent
of a half-acre planting of cantaloups were infested with the two
species. By September 20 the infestation had increased as follows:
Squash, 99 percent infested plants; cucumbers, 96 percent; and canta-
loups, 66 percent. The squash showed an averr.m:-; of 8.2 worms per
plant, the cucumbers 5.6, and the cantaloups 1.2. These three crops
are of the same age. By September 24, when the fruit ws beDi:.nir.g
to appear, many of the squash plants were dying as a result of the
worm feeding.

MELON APHID (A'his gossvynii Glov.)

Kansas. H. R. Bryson (September 26): Melon auhids were reported to be
injurious in late melons and cucumbers at Manhattna and in other lo-
calities.

Mississip-i. C. Lyle (September 19): A, Heavy infeotation on watermelon
vines at Jackson, in Hinds County, was roT'orted on August 24. An in-
festation at State College has P.lso been reported.

SQUASH

SQUASH BUG (Anasa tristis DoG.)

Maryland. E. N. Cory (Seotember 26): The squash bug has been reported
from various parts of the State.

Wisconsin. E. L. Chambers (September): The squash bug has been more
abundant than usupl all over the State this summer.

Utah. G. F. Knowlton (September 9): Numerous reports of squash bug
darnmge to squash hove been received throughout the season from, various
localities in the St.?te.











S TRAV 7ERRY

STRA5.,-_ERRY ROOT APHID (Arle forbesi .7eed)

Color-do. G. M. List (September 20): The strawberry root aphid has
seriously d -l ged several plantings of everbe!ring strawberries in the
eastern part of the State.

PEPPER

A 'EE"TIL (Coll blsmads cube Boh.)

Florida. J. A. Hyslop (Sootctber 29): A note on a cryptorhynchid weevil,
>uxenodes sp., attacking peppers in Dade Co'mty, Fla., "p*ered in
the Insect Pest Survey Bulletin, vol. l4, no. 1, p. 1S, dated '.rch
1954. Recent information has brought out the fact that the specimens
in Florida are identical with a Cub!an species, E. c-'Irc Boh. now
referred to the above genus.

BEETS

G7EEITHOT'SE LEAF TIER (Phlvct'e
California. R. E. Cambk':ll )nd J. C. Elmore (Sertembcr 5): Three hundred
acres of sugar beets in Orn.-e Countyr are heavily infested with the
celery leaf tier. Serious damage was first reported on Auagust 16. In
many fields the leaves have been skreletonized, lenvin!7 little more than
the n'j4rib. Feeding continues :on the new shoots and on the stems at
the crown. The yield in some fields is estimated st '` tons per acre,
but the sugar content is so low that the beets are h-rdly worth har-
vesting. With the infestation so heavy, it is doubtful whether addi-
tional foliage can be produced :and the 'sr content incre-sed. Adults
are so numerous that they, fly up in clouds -hen disturbed. Larvae are
feeding also on pepper plants. It is interesting to note that the in-
festations occur in the area where 7,000 acres of celery 'as gro~.
about 20 years a..-, the abandonment of ..hich was partly due to di".ae
by the leaf tier. :a-y7 parasites were observed.

_T LEAFHOPPER (Eutettix t:.IellIs Bak.)

Utah. G. F. Knovlton (September 14): Beet leafhopners wore so abuniaA.t
and active in the foothills 4 miles northwest of Dolomite as to cause
annoyance to hunters in the ar'ea. The leafhoppcrs.c-.Ised irritation
to hands and arms by biting. (September 22): Boeet Icafhoi.pers are
still very abundant in small arcas of the northern Utah broedbi
grounds, in V.'-ich Puv-ian-thistle and other favored host plants are
still in good condition for fee.dinr.











FOREST AND SHADE-TREE INSECTS


SATINT MOTH (Stilpnotia salicis L.)

Oregon. F. C. Craighead (August): J. A. Beal reports that the satin moth
has been found recently doing serious damage to introduced poplar trees,
PoTulus alba,in Oregon. Partly defoliated trees were observed near
Gervais, north of Salem, and again farther south near Albany. Old
pupal cases were very numerous, hatched egg masses were abundant, and
in some instances fully half the foliage had been eaten from the lower
part of the tree. This injury was reported br one owner to have been
present for 2 or 3 years. Early in July two adults of this species
were taken in Portland, so far as known the first authentic record of
its occurrence there.

FOREST TEITT CATERPILLAR (Ma.l-cosom: disstria Hbn.)

Wisconsin. E. L. Chambers (September 26): Large tracts of willow have
been defoliated by enormous armies of thcse caterpillrs in the swamp
lands of the State. They also attack other deciduous trees.

FALL WEBWORM (Hyohantria cunea Drury)

Color-.dD. G. M. List (September 20): The fall webworm is quite abundant
in a number of mountain valleys. The injury is especially severe on
narrowleaf cottonwood. Most of these trees along the Arkansas River,
both above and below Salida, have been la-rgely defoliated.

California. E. 0. Essig (September 9): Webs are abundant on terniIls
of young madrona and other trees in Humboldt and Mendocino Counties.
This is the most -inoticeable butfbreak ever observed by the writer.

F. H. Vyrmore (September 20): This pest is very abundant on
willow and black walnut trees along streams in the Sacramento Valley.

FLAT-HEADED .APPLE TREE BC0FR (Chrysobothris femorata Oliv.)

Ohio. E. 7. 'eindenh-ll (September 15): The flat-headed aprle tree borer
is abundant in .dogwood and maples this yoar.

Michigan. E. I. McDaniel (Soepteriber 25): The flat-headed borer was re-
ported from Ypsilanti, Jackson, Ann Arbor, Flint, Marcellus, '3nd
Holland last week. In most instances the injury was confined to
maples, although various other trees have been attacked.

WAKINTGSTICK (Di h_ rcr ra femorata Say)

Michigan. E. I. McDaiiel (Sept.mber 25): The walkingstick has appeared
in Oeiomaw and losco Counties. In the vicinity of West Branch and Tawas
City red oaks are practically defolited. The insect occurs on several
kinds of trees but confines its feeding entirely to red oaks. It has

LIBRARY
STATE PLANT P10A r











been common in this region for the p0st 5 or 6 years.


ASH

A BARK BEETLE (Lereriin.uis ac1uleatus Say)

New H-Iarshire. E. P. Felt (September 27): Ash timber beetles (L. ac:leatus)
were so abundant in ash in one locality that they caused considerable
annoyance in a dwelling, as the beetles emergcd from firewood stored
in the collar.

CARP'F'TER 'ORM (Prionoxystus robiniae Peck)

North Dakota. J. A. Munro (September 24): Several reports of infestation,
the most interesting of which are on oak at Fargo, Cass County, and on
various species of poplar at Marndan, Morton County, have been received.

BEECH

EEC--' SCALE (Crvptococcus f gI Baer.)

Connecticut. W. E. Britton (September 20): A moderate infestation of the
beech scale occurs on trees near the Mark Twain Library and on private
premises northward to Kccne.y Park in Hartford, a distance of more than
a mile.

BIRCH

BIRCH SI:F.LET,"IZER (Bucculatrix canadensisella Chamb.)

7.ssachusetts and New H-mv-shire. J. V. Schaffncr, Jr. (September 24): Seri-
ous infestations of the birch l,'af skeletonizer are very noticeable in
".n:y localities throw, .;h eastern Massachusetts and southern New 7empshire.
Much injury in sowvral towns in the vicinity of Phillips, Maine, was
noted on September 16.

FRO:TZE BIRC"-' BORER (Agrilus anxius Gory)

Michi-"-t-. 7. I. McDaniel (September 25): The bronze birch borer has been
reported from Muskegon, Holland, .I--:istce, and Ludin.ton. Trees in
these sections have suffered particulbrl'r from the dr.-i',ht. Most of
the infested trees are on natural stands and are lar.c_,'ly mature speci-
mens.

Wisconsin. E. L. Chambers (Seutember): Birch tree plaitings throughout
the St'.te '.re hoDvily infested -nd -r:e'y trees are being killed. Cut-
leaof birches in open ornamental pl.!nti.-i-E- are rapidly succumbiIF;.









ELM

AN AFPHID (Tubcrculntus ulmifolii onoel)

Iowa, G. C. Decker (Au-aQt 30): For the past 5 weeks wie have received
numerous reports and inquiries from all sections of the State rel,.tive
to the abnormal abundance of elm leaf a-hids. Practically all of the
elm trees that I have seen throughout the State h've the leaves com-
pletely covered with honeydew.

l Tebr-skn. M. H. Swenk (August 15-September 20): The outstanding, pest of
the period here covered was the elm leaf aphid. Fro' August 27 to
September 12, fro7 L:ancaster County north to Butler, Cuming, Plotte,
and Boone Counties, and northwest to Pock Ccunty, -7 complaints were
received concerning the abundance of this -a-?''id, which produced honey-
dew in such profusion that it dripped from the le"-ves continuously,
wetting houses, fences, walks, and vegetation under the trees. Mo-
torists, csoecially, complained thit it covered their windshields and
cars and attracted groat numbers of flies.

A S-.- FLY (T-nthrodinidae)

Oregon. F. C. Craighead (August): J. A. Beal reo-urts th-t ?n undeter-iined
sawfly has recently been defoliating hemlock stands in western Oregon
along the Cascade Ran,-re. He'"vy defolioti-n of western hemlock oc-
curred over an aroa of approximately 10,000 acres and lighter infesta-
tion covered about 50,000 acres. Feeding; for the w.or is about over
and the larvae arc ra-xidl7 constructing thJir cocoons. H menopt-rous
p)rasit.s are busy searching. out and parasitizinL the cocoons. Occa-
sional sawfly adults ar-oe now app.-.ring, and er'ergir-" parasites are
very "buandart. It iP not believed that the defoli-tioe this yar
will result in either heavy or widespread losse.s.

Mii:i.- E. I. VcDci-iel (Seo-,tcrber 25): This insect has been particularly
des-tructive fcr the last 4 or 5 years, and there are very few sound
hickory. trees left in the Stretc. The attack has been "-.---ravated by the
r .lou'3 cd drouir-t, which hos weakened the trees so that they are very
suscootible to attack. The nost recent outbreak occurred just out of
Datrrit. Herae a number of lar.e hickories in a stand of hardvJ-ds were
att-tck',.c and practically every tree has diar within the last few weeks.

structive to Norway pine.

Maryland. E. N. Cory (September 20): Larvae of N. pineturn and N. leconti
Fitch have been found attacking Mugho pine in Princess Anne County.

PI:E LEAF SCALE (Chionaspis pinifoliae Fitch)

Ohio. E. W. Mendenhall (September 27): The pine leaf scale is very abundant
on Scotch and Mu'go pines and on spruces in nurseries near Lancaster,
Fairfield County.

Nebraska. M. H. 5vn- (September 20): A Daw.-on Co-unty correspondent reported
that spruce trees amply provided with water this summer have been killed
by the pine leaf scale.

Utah. G. F. Knowlton (September 15): Native pines along Logsan Canyon have

Michigan. E. I. McDaniel (September 25): Despite dry weather, the gladiolus
thrips has caused no loss where corms had been treated.

Wisconsin. E. L. Chambers (September 26): The gladiolus thrips, while quite
abundant throughout the State on plantings not treated before planting,
is less abundant than last year.

Alabama. H. P. Loding (September 28): The gladiolus thrips is appearing in
nearly all plantings over Mobile County.

Colorado. G. M. List (September 20): The gladiolus thrips was found in the
State last year for the first time. The spread this. season seems to have
been quite rapid, as the infestation is quite general in most sections of
the eastern slope in the State. Many plantings have been so seriously
injured that few flowers have been cut.

Washington. R. Latta (SepterYmber): Only a few minor. infestations were found
,ii the Puget Sound district last year, but this year the insect has been
reported in numbers from all glcadiolus-Cxowing sections of the State,
including Spokane, Yakima, and WVenatchee, east of the Cascade Mountains,
,ani throughout the Puget Sound district west of the divide. Considerable
d .,ia,:e was reported by many commercial and amateur planters.

Oregon. R. Latta (September): T. gladioli was reported as d.eavinj gladiolus
at Medford. This is a new record.

California. M. L. Jones (Auguist 27): The counties of Monterey, Alameda, San
Francisco,. Santa Cruz, Sacramento, San Mateo, Marin, Sonoma, Napa, and the
extreme northern portion of Santa Barbara County were surveyed and the
.gladiolus thrips was found in each county. Because of the lightness of
the infestation in some areas, there is no doubt that several light infesta-
tions were missed. However, enough infested properties were found to indi-
cate the distribution in this part of the State. Of the 70 gladiolus
plantings examined, 41 were infested.

OLEAITD ER

POLKA DOT vWASP :.:OTH (Syntomeida epilais Walk.)

Florida. J. R. Watson (Septe-mber 24): The oleander caterpillar, the larva
of the polka dot wasp moth, has appeared in Gainesville. This insect is
apparently rapidly spreading northward. It may extend as far north as
oleanders can grow out of doors.

HOUSE CRICIGT (Gryllus domestic.-L L.)

Maine. H. 3. Peirson (August 6): A heavy infestation has been reporte'- from
Biddeford, where the crickets are invading houses located :.ear a dCu.p.
Clothing and house furnishings are being damaged.

Massachusetts. C. T. Brues (October 1): I have observed an epider-ic of
G. domestics in a part of Boston where four or five houses are overrun.
The tenants moved out on account of the continuouz- chirping at night.
Clothing and rugs were ruined by having holes eaten in them.

J. V. Schaffner, Jr. (September 25): A complain.it of crickets in a
house at Maiden was investigated on September 21. A public du.p covering
an area about 400 feet in diameter was found, where warte materialsfrom
houses and stores are placed. Fr-,o inquiries made in the vicinity, it
was learned that all houses in close proximity to this dunp were infested.
On the "other side of the dump is a small brook an. a newly built section.
Occupants of houses there were troubled also. Th-: u-i.pT, is now covered
with branches recently trinr.ed from shade trees. Although but fc-.' crickets
were noted moving about, hundreds were seen when any of the refuse was
move d.

Wisconsin. E. L. Chambers (September 26): ResiiIent .f the Huinboldt Park
section of MilwaukLee have experienced a plagie of crickets never before
known to that city. For many blocks millions of these crickets, apparently
hatching in a 6-acre swamp and city dump near the park, invaded homes,
destroying clothing, rugs, and food.

PUSS CATERPILLAR (Megalopyge operc'.laris S. aiw A.)

Mississippi. C. Lyle (September 19): Specimens h,:.v. "*...- r c.:ivel recently

Wisconsin. E. L. Cham-bers (September 26): The population has been building
up for the past fe;- suneors until the infestations in the vicinity of
seed-bearing trees almost everyv-where in the State ere practically unfear-
able, an! many cities an* villages are removingc the trees, some even
attempting to outlaw the boxelder entirely.

California. A. E. Michelbacher (September 22): At Pleasantbn on September
14 the boxelder bug was observed congregating by the thousands on a
single tree, the trunk and limbs of which were covered with them.

BLACK WIDOW SPIDEF. (Latrodectus nactans Fat.)

:I-;braska. M. ]1. Swenk (August 15-September 20): During the summer and fall
there have been an unusually large number of reports of the hour-glass
spider from western Nbr .ska. They have been especially' numerous in
Dawes anC Box Biutte Counties. In the former county, ;.rin the period
here covered, three persons have been made seriously ill because of the
bite s.

Colorado. G. M. List (September 20): Inquiiries in regard to the black widow
spider ha-e been much more numerous than usucl. This may be due partly
to the publicity given the spider by various newspapers; however, our own
findings indicate that it is much more num-norous thai usu; 1.

CATTLE

SCREW TJ"RM1 (Cochlionyia spp.)

Florida. J. R. Watson (Smpter'ber 24): The screw worm infestation continues
to grow in severity, with heavy losses to hogs and cattle. One or two
cases have been reported on man. Forty counties are said' to be infested,
but the northern part of the State is more seriously affected than the
southern part.

Georgia. T. L. Bissell (September 26): Numerous cases of infestation of
wounds have been found at the experiment station and in Spalding County
in September. Mu.es, hogs, and cattle hwze been injured. The insect has
not heretofore been recognized in this locality.

Alab-rma. J. M. Robinson (Septemboer 21): Central and southern Alabeaa are
moderately infested.

Mississippi. G. L. Bond (September 19): Southern Mississippi is experiencing
the worst outbreak this State has ever known. This insect has caused a
loss of about 50 percent of the sheep, along with i-any hogs, cattle, and
other animals. Besides the injury to domestic animals, several infesta-
tions of human boeins have been reported.

K. L. Cockerhaa (Se-otember 3): Reports of severe injury to livestock
along the Mississippi coastal plains have been numerous for the past
several weeks. Shecp are reported to be more severely attacked than any
