Vol. 17 October 1, 1937 No. 9


At the last of September grasshoppers were still doing damage from
Illinois to southern Minnesota and southward to Missouri and" Oklho-noia. They
also continued to be destructive in the Great Basin. Over much of the in-
fested territory egg laying was well under way.

Scattering reports of damage by wireworms were received from Pennsyl-
vania, North Dakota, and Washington.

During the month outbreaks of the garden webworm occurred in Indiana
and Michigan. The principal damage was to alfalfa.

Hessian fly is abundant in volunteer wheat in parts of Ohio, Wisconsin,
North Dakota, and eastern Missouri.

Infestation by the European corn borer in 10 counties in Wisconsin was
found during the summer. The insect is building up heavy populations in
western Pennsylvr.nia.

Heavy damage to small grain and alfalfa seed by Say's stinkbug was re-
ported from Utah and Arizona.

Late in summer a large codling moth population developed from northern
Ohio to northeastern Kansas.

The flatheadod apple tree borer was seriously dnnniinC apple trees from
Indiana and Nebraska southward to Oklahoma and Missouri.

The oriental fruit moth was more abundant in Ohio than it has been for
several years. It was also reported as abundant in Connecticut and as doing
some damage in Georgia and Mississippi.

Heavy infestations of the grape leafhopper were reported from Kern
County; Calif., and of the grape leaf folder from the San Joaquin Vnlley.

- 355 -

- 3s6 -

The walnut caterpillar was reported in destructive numbers from Virginia
to Florida and westward to Wisconsin' ad Okiahoma.

*....The Mexican bean beetle became abundant in extreme northwestern New
York, in Virginia, Ohio, and Indiana, also in'the Gulf region.

The harlequin bug is building up heavy populations in southeastern ,

The corn ear worm was reported as causing commercial damage to peanuts
in Oklahoma. This is the first report of serious damage by this insect to
this crop in Oklahoma.

The worst infestation of tobacco by hornworms ever reported from Mary-
land occurred this year. IDanage was most serious in southern Maryland, where
entire fields were stripped before harvest, and severe damage was later done
in the tobacco barn.

Infestation by the pink bollworm in the Big Bend area of Texas was
heavier and earlier this year than last.

Late in the season considerable defoliation and ragging of cotton by
the cotton leaf worm occurred over much of the Cotton Belt.

The bollworm was quite generally prevalent from Georgia to Texas, al-
though upland cotton was practically made before worms became very numerous.
Serious damage, however, occurred in parts of Texas.

The locust leaf miner occurred in outbreak numbers in Virginia aid
North Carolina.

The larch sawfly is at a very low ebb in the Lake States.

The European spruce sawfly has increased to alarming numbers through-
out the northern part of the New England States. ..

Severe damage to lawns by the hairy chinch bug was. reported from New
York, Connecticut, Rhode Island, and Ohio.

An unusual number of reports from the northeastern fourth of the
United States indicates an outbreak of fleas.



The light and patchy grasshopper outbrewik in southwestern Manitoba
was greatly aggravated late in July and early in August: by extensive flights
of grasshoppers from the southeast, with the result that much head damage
was done to late crops and prospects of a severe outbreak in 193g were con-
siderably increased. In Saskatchewan'heavy migrations of grasshoppers in
southern areas md their concentrations on late crops elsewhere continued to
reduce feed supplies. Preliminary surveys revealed important infestations
pr-ctically throughout the agricultural area. While these were light in
many newly infested areas, 'the area of severe outbreak had also spread
markedly, especially in the northwest. Exceptionally-severe and general
outbreaks are indicated in the Province for next spring. Severe damage and
crop loss occurred in.some localities in southern Alberta. Althougih 1937
was a peak year for grasshopper abundance in the interior of British Columbia,
crop losses were small asa'result of control efforts.

Moderate, infestations of the M'lormon cricket were reported in several
localities in'Manitoba and Alberta.

Outbreaks of the armyworn occurred in parts of eastern Canaia and the
Prairie Provinces. The outbreak in Nova Scotia and Prince Edward Island was
the worst in nearly two decades. :."oderate-to-light infestations developed in
New Brunswick and southwestern Ontario. With the exception of the southwestern
municipalities and a strip eastward along the international boundary as fa.r as
Manitoba, practically the whole agricultural area of Manitoba suffered heavy
infestations. Outbreaks of different degrees of severity also occurred in

Extensive daria:e to field and garden crops by seccnd-yeor white grubs
occurred over a wide area in southern Quebec.

Considerable loss of wheat from the attacks of the wheat stem sawfly
was reported in the prairie sections of Saskatchewan wherever crops matured.
Losses in Alberta this season were more extensive and severe than in 1936.

A gradual resurgence of the hessian fly population is occurring in
southern Ontario, owing to the practice of early seeding.

Say's stinkbug is quite abundant in Alberta and occurs over- a wide
area in this Province and Saskatchu'vui. The area extends from the inter-
national boundary, west to Cardston, Alberta, east to East Poplar, Saskatch-
ewan, and north to Calgary,' Alberta, mn d Algask and Ardath, S.iskatchew-i.

An outbreak of the beet webworn of probably unprecedented severity and

widespread distribution developed in Saskatchewan and increased the seri-
ousness of the feed situation in drought areas by destroying weed growth
otherwise available .-for.. feed. Outbreaks also occurred in southern Alberta.

Field beans in southern ari wreinfested with he green clover
worm,; -but not to an extent to cause stripping of the plants.

S, A general decr6ast in the abundance of .the European earwig in in-
. tested areas in British Colubia waw ,reported. .Inportedparasites of the
earwigs have been,widely distributed *in these. sections iz recent years.

:. Injury tp, apples "by thee first. :,bruod of. codling, moth wa's reported
to be unusually severe "in the ITiagara district,., the Georgian Bay district-
and eastern Ontario." ...

Aphids affecting' orchard trees have nowhere been reported in' out-
break form. The apple aphid and-the rosyapple aphid were noted as of
minor importance this yqear in- the Niagara district, .,.,..

Outbreaks of'the apple and thorn skeletonizer, apparently local-
'ized, occurred in parts of northern Nova Scotia and Ontario.

The infestation of second-brood. oriental fruit, moth was'low in
the Niagara district. A average twig infestation of 3.4 percent was"
recorcled in young peach orchards. The infestation in southwestern
Ontario was higher than in 193. -.

The pear eaf blister :mite is more prevalent than usual, particu-
larly on young.pear trees, in parts of southern Ontario. A local severe
outbreak occurred in New Brunswieck. .

A distinct increase in numbers in the first generation of the
European spruce. sawfly was general in New Brunswick, and in the centre
of the Province large areas were beginning.-to show defoliation. In
Quebec new severe attacks on spruce Bonaventure County, and
heavy samples,. of. larvae were received from Kamouraska and Montmagny
Counties.. West of the St. Lawrence River; the sawfly is now known to ex-
tend from Lake Saint John westward to Lake Temiskaming.

The black-headed budworm is evenly distributed and fairly abundant
from Saskatchewan to the Gaspe, .with local concentrations in northern
Algoma. .

Increaed infestation and damage to balsam fir by the, balsam woolly
aphid has developed in the Maritime Provinces.
The larch sawfly has increased, in numbers in, parts of Nova Scotia
and New Brunswick. An infestation was discovered south V'f'Silverton,:
British Columbia, 62 miles .farther west than previously recorded.




Illinois.' W. P. Flint (September 20,).: In moat sections of the State there
has been a marked decrease in the numbers of grasshoppers from August
20 to September 20. 'Some sections still have moderately heavy infesta-
tions. Egg laying is now in full progress, with the weather ideal- for
the deposition of eggs.

Wisconsin. E. L. Chambers (September 20):. Practically every county reported
.serious damage to certain crops--alfalfa, tobacco, orchard, and garden;
and 52 out of 71 counties spread more than 10,500 tons of bait. Serious
damage is still being reported.

Minnesota. A. G. Ruggles and assistants (September): Grasshoppers are abun-
dant in the southern third of the State.

Iowa. H. E. Jaques (September 24): Grasshoppers are still very abundant
throughout much of Iowa, but their present damage, with the exception of
garden and some other fall crops, has been quite negligible. We have
recently taken a number of specimens of Schistooerca lineata Scudd. in
Henry County. This is a new record for this species in the eastern half
of the State.

Missouri. L. Haseman (September 23): During September grasshoppers have
continued to attract attention; in fact, with the scarcity of rain over
most of the State and the shortage of wild vegetation, they have tended
to move onto late corn, fruit trees, and garden crops, more perhaps than
earlier in the summer. Through central Missouri, Melanoplus.mexicanus
Sauss. is now by far the most abundant and active species. The second
brood is maturing, mating, and laying eggs at this time. M. differ-
entialis Thos. is present in numbers around the edges of cornfields and
other tall vegetation, and likewise is mating and ovipositing. Since
about the first of September very few of the two-lined grasshoppers
(M. bivittatus Say) have been observed. Unusual numbers.of the Carolina
locust (Dissosteira carolina L.) have been collecting in bare places,
being more abundant than I have seen them any time during the past.
several years. Our common red-legged grasshopper (1. femur-rubrum Deg.)
in central Missouri, appears with M. mexicanus at the rate of about 1 to
10 of mexicanus.

Kansas. H. R. Bryson (September 25): Grasshoppers are still quite abundant
and are a threat to the early sown wheat. Alfalfa fields in localities
of very low rainfall have been considerably injured. Eg. deposition is
taking place at a rapid rate.

Nebraska. M. H. Swenk (September 22): While the corn crop has passed the stage
where grasshoppers may damage it seriously, damage has been rather.heavy
to late summer seedings of alfalfa and the early seedings of winter wheat
and rye. Over 1,000 tons of bait natorials have been used in the last 30

days. Use of bait has been particularly heavy in the southwestern and
western third of the State, although large quantities have been used
throughout the entire winter wheat-growing section.

Oklahoma. C. F. Stiles (September l1): Grasshoppers are congregating in
most places and depositing eggs. However, on the west side of the State
they are doing serious damage to fall-planted wheat. Alfalfa is also
being seriously damaged in some of the central counties. Considerable
poisoning is being done in the western counties. The species most common
are M. differentialis and M. mexicanus.

Utah. C. J. Sorenson (September 20): M. femur-rubrum is very abundant in
Millard, Cache, and Box Elder Counties. M. packardii Scudd. is very abun-
dant in Sanpete, Cache, Juab, and Millard Counties. M, biyittatus i-s very
abundant in Sanpete, and M. mexicanus in Tooele, Millard, and Juab Counties.
Camnula pellucida Scudd. is very abundant in Tooele County,

G. F. Knowlton (September 10): Grasshoppers are more abundant in
most parts of Cache County than they have been for several years. They
are damaging alfalfa seriously in North Farmington, east of Layton,-and
southwest of Salt Lake City, in northern Utah. Eight hundred acres of
alfalfa and several thousand acres of range land were heavily infested
on ranches along Indian Creek, in San Juan County.

WIREWORMS (Elateridae)

Pennsylvania. M. D. Leonard (September 22): Reported to have been very-in-
jurious to various vegetable crops, especially tomatoes," in Chester County
this summer.

North Dakota. J. A. Munro (September 17): A survey has been conducted in
potato fields in Traill, Grand Forks, Walsh, and Pembina Counties. Some
fields show only a small percentage of the tubers injured, while others
in nearby areas show injury as high as 69 percent. The most serious in-
festations have been found in the Ho,'ple and Crystal vicinities of Walsh
and Perbina Counties. The predominating species appears to be Ludius
aereipennis Xby.

Washington. E. 7. Jones (September 23): Linionius canus Lec. was found to be
damaging fall spinach and lettuce early in September at Walla Walla.

JAPANESE BEETLE (Po-oillia japonica Newnm.)

Connecticut. W. E. Britton (Septe.iber 23): Several cases of rather severe
grub injury to lawns have come to our attention. Heretofore most of the
damage has been caused by the adults to foliage and flowers. Adults have
been received for identification from Greenwich, New Haven, and Woodmont,
and several lots of larvae from New Havon.

New Jersey. C. H. Hadley (August): Heretofore feeding by beetles on the fruit
of grapes has not been observed, and it was thought that such feeding did
not occur. However, on August 13, extensive feeding by beetles on bunches
of grapes was observed in a vineyard at Holmdel.


ASIATIC GARDEN BEETLE (Autdserica castanea Arrow)

Connecticut. W. E. Britton (September 23): Grubs are now injuring lawns,
often in association with those of An'.mala orientalis Wtrh. and P.
japonica, particularly in the New Haven region.

CRIEiTTAL BEETLE (Anomala orienta.lis Wtrh.)

Connecticut. W. E. Britton (September 23): The grubs of this insect continue
to da;mi-ge.untreated lawns in New Haven and West Haven. "-.ny separate lots
of grubs have been received for identification and inform-.tion regarding

W7HITE-FRFI!GED BEETLE (Naupactus leucoloma Boh.)

Alabama. J. M. Robinson (September 19): Adults are still depositin- eggs in
the infested area in Covington and Geneva Cbunties. Some have deposited
as many as 1,400 e,:7s.

FULLER'S ROSE BEETLE (Pantomorus godmani Crotch)

Georgia. T. L. Bissell (September 17): This weevil is abundant, possibly
abnormally so, feeding on Lespedeza bicolor, soybeans, and coffee weed
at Expeocriment.

A TENEBRIONID (Pelecyphorus densicollis Horn)

Washington. H. H. Hatch (September 22): Enormous numbers of adults were seen
swarming in the sagebrush just east of Prosser on September 20. At times
in the past this species has been so abundant as to clog irrigation ditches
between Presser and Kennewick.

A FALSE WIREWORM (Eleodes sp.)

Kansas. H. R. Bryson (September 26): The false wireworm has been reported
causing considerable injury to wheat in Kansas, as far east as Saline.
Deficient rainfall in the wheat district and much early so'.mn wheat are
contributing to the arcLur-t of injury.

ARMYTORM (Cirphis unipuncta Haw.)

Maine. H. B. Peirson (Sepotember l14): A large flight of moths occurred at
Bar Harbor August 25.

Rhode Island. A. E. Stene (September 21): Late in August we had an outbrc-ak
of armyworms in Providence. County, rore sever'c than the earlier ones in
Kent and Washington Counties. A large millet field was destroyed, aid
the caterpillars marched to an adjoining field which fortunately was an
old pasture where they found little food. Here also parasitic flies were
abundant and hardly a caterpillar could be found without from 1 tr 10 or
even 15 eggs attached.


Oklahoma. F. A. Fenton (Sgptember 20): Armyworms and several species of
cutworms are uunlIually numerous and -are cutting doven the young wheat
plants in many fields.

S "' .WHITE-LINED SPHINX'(Sohinx lineata F.)'

Maine. H. 3. Peirson (August): This moth has been seen abundantly this year
hovEring over flowers in garden.- ii centraln ainid southern Maine. Numerous
inquiries have also been received concerning it from various places in
the State, it being often mistaken'for' huringbird. -

Michigan. R. Hutsoh (September 20)-: Has been reported from all over the State.

Iowa. H. E. Jaques (September 24): Has been very abundant in both the larval
and tacdult stages throughout the Sta'te.- 'The larvae in many cases are
feeding on purslane and other weeds, so that their presence has not
created a serious problem.



HESSIAN FLY (Phyto'phaga destructor Say)

Ohio. T. H. Parks (September): While the infestation in the 1937 wheat crop
was very light,, eggs are now abundant on volunteer wheat in some counties
showing a very'lo1w infestation in July.

Wisconsin. E. L. Chambers (September 120): Once so abundant" that it resulted
ih the abo'ndbnin'g of winter wheat raising in the State, the hessian fly
is making its appearance on grain after many years' absence. Eggs and
larvae observed on volunteer grain in fDane and Jefferson Counties.

North Dakota. J. A. Munro' (August 6): Specimens collected on one of the
Station plots at Fargo. Some of the plots are infested as high as 50
pecrcent--Hope: Roeward cross. (September 17): An examination' of mos-t of
Sthe varietal wheat plantihgs on the station grounds brouiLht the average
infestation rather low, about 4 percent.

Missouri. L. Hasoman (September 23): Summer and fall stubble surveys indicate
a scarcity of live flaxseeds over a considerable part of Missouri. How-
ever, throughout the northeastern and most of the eastern and southeastern
parts of the State they are present in sufficient numbers to- cause -worry,
where growers found conditions favorable for seeding early. Over' most of
the State, however, scarcity of rainfall is holding back seeding or, at
least, wheat sprouting, so that: it now appears that comparat-ively little
wheat in this State will be up and exposed to flies even where they are
19 -1 *i.r it' enough to cause -worry. '

Kansas. H. R. Bryson (September 25): Hess;ian "fly is not depositing eggs at
this writing. : : '

CHINCH BUG (Blissus leucopterus Say)

Illinois. W. P. Flint (September 20): Very spotted and moderately heavy in-
festations of chinch bugs exist in many small areas in the south-central
and southern parts of the State. The latter part of August and first of
September have been very, dry, and while these insects appeared late in
the season they are in most cases developed sufficiently to enable them
to hibernate in the adult stage.

Kansas. H. R. Bryson (September 25): Chinch bugs are present in considerable
number:;, in sorghum fields but are doing no damage.

APPLE GRAIN APHID (Rhopalosinhum prunifoliae Fitch)

Nebraska. M. H. Swenk (September 22.): Whert plants in Frontier County are
being killed out by the anple grain aphid.

Correction--In the Insect Pest Sui-ve: Bu'lletin Vol. 17, September L, 1937, No.
7, PngeO 342, regarding the sawfly in Ohio, by E. J. Udine, the heading
should read Black Grain Stem Sawfly (Trachelus tbidu_ F.), instead of
European Wheat Stem Sawfly (Cciphus us L.)

C OR.:

CCRI EAR 7ORi.1 (Hqcliothis obsoleta F.)

Pennsylvania. M. D. Leonard (September 22): C. A. Thomas reports thr.t corn
err worm w5s scarce in eastern Pennsylvania this season.

Illinois. T7. P. Flint (September 20): A he-vy infestation dcveloncd late,
building up to a maximum during Seotemb-r.

Wisconsin. E. L. Ch.mubers (September 20): H.7s been r-Dorted_ doin; damage to
chrysanthemums in several commercial florist establishments in Milwaukee.

Tennessee. L. B. Scott (September 3): Very abundant in central Tennessee.
Damage has beon severe in corn and tomatoes, but probably iore severe in

K.nsas. H. R. Bryson (Septembcr 25): Abundant in sorghun hc-ds.

Utah. G. F. Knowlton (SepTtember 6): Infcst'ati>n wvas hc.vy in corn, but to date
rather light in tom-.toes at C'-stle Dale and Hunti-o... Corn a Torrs
have daiiaged most of the sweet corn at Du.chesne and Price, and 10 percent
of the toriatoes were c.:-c' ;od in one field examined at Price.

EUROPFJAIT COCRIT BORER (Pyr-usta nubilalis Hbn.)

Connecticut. N. Turner (September 20): Late s17eet corn ,t the Mt. Crnmcl Farn



was unusually heavily infected, about 90 percent of the oars being
attacked. We have several reports of similar damage in southern
Connecticut. Unsprayed dahlias were also heavily infested,. dissections
sho'7ing as many as 73 borers in a single plant. Many second-instar
larvae are present and P few cast pupal skins, indicating that. there
may be a partial third generation this year. Injury to gladiolus has
been reported, and larvae in stalks received from Westport.

Pennsylvania. R. M1. Baker (September): The infesta-tion in Erie and Crawford
Counties has been building up until, on a recent survey, 30 percent of
the cornstalks in some fields were found to be infested. The infesta-
tions in Centre, Clinton, and Lycoming Counties arc showing only a very
slight increase.

Wisconsin. E. L. Chambers (September 20): More than 60 fields'of corn were
found infested in 10 counties bordering on Lake Michigan.

CORN ROOTWORM (Diabrotica longicornis Say)

Connecticut. W. E. Britton (September 21): Adults damaged corn by-' shredIing
the husks and eating the kernels at Lakeville. Twelve' were submitted for


GARDEN WEB70RM (Loxostege similalis Guen.)

Indiana. J. J. Davis (.September 25):. More abundant and destructive to
alfalfa than for'a number of years, destroying a large acreage of this
year's sowing of alfalfa in the n-rthern two tiers of counties. The
first report came from L'agrange County, August 26, 'and" by September 2
the wvebwor}ms had eaten three-fourths of all the new alfalfa seeding in
the county. Reports continued through the month of September, most. of
them coming in early September. -

Michigan, R. Hutson (September 20): The garden vlebworm is destroying n aflfa
seedings in southern Michigan...

Oklahoma. C. F. Stiles (September 1S): Has completely defoliated many of
the alfalfa fields throughout the central part of the Stte..' Cotton in
some instances has also been damaged and where food has been scarce, this
pest has fed on a variety of plants. This is one of the worst outbreaks
that has ever been observed in Oklahoma.

ALFALFA CATERPILLAR (Eurymus eurytheme Bdv.)

California. C. S. Morley (September 3); The butterflies were very numerous
and in the Kern Lake. district larvae injured half-grown alfalfa to the
extend that several hundred acres had to be cut before maturity in order
to stop the invasion.

ALFALFA 7?EEVIL (Hypera postica Gyll.)

Utah. C. J. Sorenson (September 20): .Alfalfa weevil very abundant in Piute
County. Serious damage in 1937.

California. A. E. Micholbacher (September 20): Larval and adult porulitions
continue to b. very smpll. In the San Joaquin Valley on September 17 a
few individuals were collected in two fields, while in the San Francisco
Bay area a few wore taken in a single field.

GRAPE COLASPIS (Colasnis brunnea F.)

Arizona. H. F. Tate (September 20): There has been a serious outbreak of this
beetle on seed alfalfa this fall. There are 10,000-12,000 acres of seed
alfalfa in Yuma County.

SAY'S STINKBUG (Chlorochro2 sayi Stal)

Utah. C. J. Sorenson (September 20): Severe damage; 50 percent to barley and
considerable to first-crop alfalfa seed in New Castle, Iron County,
a nd in Millard County. *Moderately abundant to very abundant. In Wash-
ington County, moderately abundant, with damage to sugar-beet 1:eed.

Arizona. C. D. Lebert (September 2): Insnector Mendcnhall rtorts 30 to 35
percent injury to seed alfalfa from C. sayi and plant buw, Lygus sp.,
injury in the Gila Valley and near Safford.

TARNISHED PLANT UG (Lye-s pratensis L.)

Arizona. H. F. Tate (September 20): There has been a serious outbreak of
the tarnished plant bug on s:ed alfalfa this fall.

POTATO LAFHCPPER (Emroasca fabae Harr.)

Kentucky. 7. A. Price (September 24): Severe lerfhopper injury to Lalfalfa
in the northern section of the State.


GREE-T CLOVER 7ORM (Plathrpenft scabra F.)

Ohio. N. F. Howard (Seotember 20): At Colum!.us during; the early pert of
August green clover worm was rather scarce, but in September it'was found
to be quite numerous, although not as -bundan.t as some yer ...



CODLING MOTH (Carpocapsa pomonella L.)

Ohio. T. H. Parks (September): Codling moth developed into a problem princi-
pmlly in.Lawrence County on the Ohio River, and in Lucas and Ottawa Counties
:in: northern Ohio. The month of August was dry., and bait-pan catches at
Columbus and Toledo showed increased moth activity between August 10 and
20. This was followed by' injurious entrances after the middle of August.
Orchards checked in central and eastern Ohio show very low infestation.

Michigan. R. Hutson (September 20): The second brood was not so severe as
was expected. .

Missouri. L. Haseman (SepTtember 23): During September there has been a steady
emergence of third-brood moths ith .an unusually sharp pickup in abundance
in northwestern Missouri during the last few days of August.

Missouri and Kansas. H. Baker (August 31): The second brood appears to have
caused more dam-ge in northwestern Missouri and northeastern Kansas than
any other one brood since the spring brood of 1934. Well sprayed.orchards
show many stings and poorly sprayed ones are very wormy. Greatly increased
bait-traps catches of moths which began August 27, indicate that third-
brood damage may be heavy if weather conditions are favorable.


Missouri. L. Haseman (September 23): A second generation appeared in September.
The larvae are now largely full fed and where the foliage of apple has not
had a good spray coverage a good deal of damage to the foliage has been done.

APPLE LEAFHOPPERS (Cicadellidae) .

Massachusetts. M. D. Leonard (September 22): Leafhoppers, Typhlncyba pomaria
McAtee are very injurious in at least, one large orchard in the State and
presumably abundant in others, according to an authentic report received
during August.

Connecticut. P. Garman (September 21): Infestation by the white apple leaf-
hopper (T, pomaria) is irregular; some orchards.heavily infested, others
not at all.

Virginia. A. M. Woodside (September 20): The white apple leafhon-per is present
in large numbers in many orchards of Augusta County, but no severe infesta-
tions have been observed.

Missouri. L. Hasoman (September 23): During September the various species of
leafhoppers on apple have been unusually abundant and injurious to the
foliage. There seems to have been a, rapid increase of leafhoppcrs during

the last few weeks. This, combined with the scarcity of rain, caused
considerable drop of the Jonathan apples early in September, though during
the middle yrd latter part of September Ihere Jonathans were not picked,
the dropping of the fruit largely stornped,

FLATHEA:.ED APPLE TREE BORER (ChrysobotlHris femorata Oliv.)

Indin'. J. J. Davis (September 25): Continues to be reported from many nprts
of the State damaging apinle and maple.

Missouri. L. Hascman .(September 23): Although adults were more abundfJnt earlier
in the summer than we have ever seen them in Missouri, ther' is really less
damage showing up during SeDtem-i-er than occurred during th past two or
three falls. Unfortunately, there are plenty of the borers in weakened
trees and developing on limbs and exposed trunks in healthy trees, but far
less than we expected.

Nebraska. M. H, Swenk (September 22): Complaints of damage to fruit .nd shaae
trees, principally ash, elm, willow, and flowerin,-- crab apple, were re-
ceived from August 20 to September 22 from several counties.

Oklahoma. F, A. Fenton (Sentember 20): Continues to be the most important
tree-boring insect on shade trees. Renoorts arc being received from widely
scattered parts of the State.

ROUJrITIFArED APPLE TREE BORE-- (Sancrda c-n.ida'F.)

Missouri. L. Hasemar- (September 23): At Columbia the young larvae hatched
during August and by eprly September most of them were through the outer
bark feeding on the cambium. By the middle of September, many of th ee
had developed tunnels 2 and 3 inches in length, and the grubs were over
2 inch long. In some orchards they have been unusually abundant, an'd
where not removed promptly seriously da-.,!.2-ed both young 'and bearing trees.

PLUM CURCULIO (Conotrachelus nenuphar Hbst.)

Georgia. 0. I. Snaop (September 4): Jarrin[; records showed a considerable
increase in adult curculios in reach orchards -t Fort Vollc-y, centr-'l
Georgia, early in September. An averp- of 1.5 beetles pnr tree were
taken by jarring on September 4. This is more than f..t ar.n time since
Arril 3, when adults were appearing from hibcrnntion. 7.. father conditions
have been favorable for the development of the second -eerIr-ation, and
the suud-n increase- of adults in peach orchards is b1. lieved tb be due
largely to the recent emergence of second-generation adult. from tiu'- sil.
Many of the beetles caught on Septembc-r 4 were clean and Icoikd tLo be new
individuals. Seventy percent of the first-,. neration females deposited
second-generation eggs, which is more than usual.

GRAPE LEAFHOPPER (Erythroncura comes Say)

Missouri. L. Haeeman (September 23): During the last das of August and
throughout September, leafho'ppers on grapes increased greatly in numbers
in central MIVissouri and leaves on the more susceptible varieties were
badly spotted by feeding. Late sprays, however, largely eliminated the
brood of immriature hoppers.

Utah. G. F, Knowlton (September I0): Have killed from 50 to 95'percent of

the leaves on most Vir-inia cre'pers, obs- rv; recently in northern Utah.

Missouri. L. Hascrmn (September 23): -Throughout practically the entire State
the second-gencrhtion larvae ate the foliage from walnut, hickory, and
pecan trees. Early in September larvae forced to migrate in search of food
,in central Missouri fairly carpeted the ground arriund walnut trees that were
stripped. Many medium-sized trees had from 15 to 50 colonies of these worms
feeding-on them. This insect has been serious in recent years but never
has it clone the.damage that it did this fall. The season is late enough
so th:,.t no serious injury, will be done to the trees. In many places the
larvae wore so abundant that most of the later colonies died of starvation,
though great numbers have gone into winter quarters.

Oklahoma. C. F. Stiles (September 18): The second brood has defoliated a large
percentage of the pecan and walnut trees throughout the State. This is the
second time that these trees have'been defoliated this season. The growers
are considerably worried about the future of the pecan industry is many of
the trees' are weakened and will die d.iring the coming year.

California. A. E. Michelbacher (September 20): In a part of central Cali-
fornia the larvae are seriously infesting tomatoes. In Yolo and. -Sacramento
Counties, despite rather extensive control programs, the infestation in
many fields ranged from 10 to 20 percent. In one field near Dnvis the in-
festation was slightly more than 40 percent. In other areas, such as the
Brentwood and Gilroy districts, most of the infestations are small,
TOMATO PINWORM (Gnorimoschema lycopersicella Busck) .

California. J. C. Elmore (September 21): Most of the tomato fields in southern

the insects had all but destroyed his snap beans. This i-:dicates that this
pest ias reached the northwestern section of the Stato in destructive num-

*Virnii-.i H. G. walker (September 25): Very abjrdan.t in many b... fields in
Elizeabeth City County and rather abundant in some fields around Norfolk
and on the r-.stern Shore of Virginia.

Ohio. N. F. Howard (September 20): It has been more nuinrrous in central Ohio
than average, but probably not as injurious as it was some ye-,are t.
Along the Ohio River at Scuth Point, the beetle was extremely numerous and
injurious earlier in the season, but a small area in that section suffered
from drought and heat during August anr.d the early part of September and the
infestation was greatly reduced.

Indiana. J. J. Davis (September 25): Has ruin-:.1 crops in scattered localities

from moderate to severe on the extensive cauliflower crop in e,-stern
Suffolk County. This started wiith the fall crop early in August, running
through to date, with several short periods of lesseninr- of larval activity
because of rains.

Virginia. H. G. Tal,.ker (September 25): An outbreak started at Norfolk about
3 or 4 weeks ago, but a high percentage of the loopers died from a disease
before th,' had done much damage.

the seed-corn maggot. ... .



PEPPER WEEVIL (Anthonomus eugenii Cano)

California. J. C. Elmore (September 21.): Th- pepper weevil has caused light
pepper drop this season, except in a few cases. Two e-rly bell ecprer
fields near Santa Ana were 100 percent infested on September 15, but the
large chili-pepper acreage in Orange and Los Angeles Counties has a good
set of early pods beyond weevil attack. Population has built up in late
pods but actual losses will not be heavy except in the number-two ;rade.
The infestation was much higher in the San Luis Roy Valley of San Diego
County, owing to milder winter temperatures. Treatment has been necessary,
untreated fields having suffered heavy losses.

BOLL MEEVIL (Anthonomtxs grandie Boh.)

Georgia. p. M. Gilmer. (August 30): In southern and central Georgia weevils
are abundant in, all fields. In late plantings of short-staple cotton
bolls were p-oroduced only about, one-half way up the plant. Undusted fields
of Sea Island cotton, show very heavy loss in-bolls, while dusted fields
show satisfactory control-of -the. late weevils. The third-brood weevils
are now emerging in considerable numbers.

W. L. Lowry (August 28): In 1owndes and Echols Counties boll weevils
have increased rapidly during the last- 2 weeks and practically all fields
of Sea Island cotton are devoid of squares, blooms, and young bolls. A
fairly good crop of rh .ture bolls-is present injrestricted areas.

T. L. Bissell,(Septcmbr,'r' 1.7.) : -Very injuriouis to Sea Island cotton at -
the station at Experiment, attacking squares and bolls. Throe or four

E. V7. Dunnam (September 4): In 'Tahin.ton County the weevil is
damaging the late bolls and practically destroying all extremely late
cotton. Excessive rains have caused most -farmers to stop poisonijig.,
(September 25): It is estimated there are at least one hundred times as
manny weevils on this date as there were l.,st season.

C. Lyle (September 24): Reported numerous in ,2i sections of -the
State, injuring most of the squares ?jnd some of the young bolls. -

Louisiana. R.C. Gaines (September l1): Conditions continue favorrbleo for the
multiplication of boll weevils annd indications are now, that unless leaf
worms soon become sufficiently numerous to stripthe cotton, a large num-
ber will enter hibern-.tion.
