THE MORE IlffORTANT.EECOEES EQR SEPTEIvBER

Infestation By the 'ivhite-.f ringed Beetle has Been found recently, in the
vicinity of HattiesBurg, Miss., extending for several miles along a railroad
right- of- T\'ay,

The fall nrmyworm outBreaks in loc'''lized areas uero reported from Mary-
land southward to Plorida and across the Gulf region to Texas,

The velvetBean caterpillar has Been damaging peanuts , ’ velvetBeans , soy-
Beans, and a numBer of other field crops in AlaBama, Georgia, and Plorida.

Heavy infestation By the wheat jointworm was reported from Missouri, and
minor infestations from Delaware and Maryland.

Hot, dry weather in August and SeptemBer was apparently favoraBle to
seconcUBrood chinch Bug development a.nd rather heavy infestations are reported
from Indiana to NeBraska and Missouri,

Codling moth infestation in the Hudson Valley is the most severe in the
last 3 years. Heavy infestations ^re also reported from Virginia, Tennessee,
Indiana, and Missouri,

Populations of the plum curculio in the Port Valley section of Georgia
are higher than average.

The pear psylla has Been recorded for the first tine from Idaho, the in-
festation in the Spokane area in Washington having Been found to extend across
the State line.

Heavy infestation of tomatoos By the corn ear vi-orm occurred in central
California,

Unusually late damage By the Mexican Bean Beetle is reported from the Soutl
Atlantic States and from the ea.storn part of the lower Mississippi Valley,

Boll weevil infestations are heavy over most of the Cotton Belt from Texas
eastward, especially in the coastal regions. No damage has Been reported this
year from Missouri and Tennessee.

The cotton leaf worm seriously stripped cotton over extensive areas in

Texas, It reached most of the other cotton States too late to cause much damage
this, year.

^The fall weBworm is generally prevalent in Ne^" England and the South
Atlantic States. Hea^/y infestations also reported from the East Central States
southward to the Gulf and westward to Minnesota and NeBraska,

CEREAL AND FORAGE-CROP INSECTS

WHEAT

HESSIAN FLY (Phytophaga destructor Say)

Massachusetts. F. W, Poos (August 24); Flaxseeds found' in typically injured
plants in wheat stuhhle today at Lenox, Berkshire County. Wheat grown
on this farm continuously for a number of years. Only one 12-acre field
foxand infested,

Missouri, L, Haseman (September 26); Oiving to the prolonged diy weather through-
out the State, there is no evidence of early emergence. Stubble infesta^
tion comparatively light, so little ccnoorn as to this pest. Little of
the crop expected to come up until after the fly-free date,

Kansas, E. T. Jones (September 25): Although many spotted infestations of

spring puparia in stubble have been found in fields throughout the eastern
half of the State, and although much volunteer is present in most fields,
examination of volunteer has shown no infestation. Dissection of puparia
in field stubble indicates no emergence, with about 30 percent of the
larvae desiccated,

WHEAT JOINTWORJ^ (Hgjrmolita trit ici Fitch)

Delaware, F, W. Poos (July 2S); Collected in wheat stubble at New Castle today.
Not previously reported from Delaware, according to our records,

Maryland, F, W. Poos (July 24); Collected in wheat stubble at Knoxville today,

A previous record in Mainland was a description of injury by a farmer in

1909.

Missouri, E, T, Jones (September 25) t Severe infestations found on several

hundred varieties of winter wheat in test plots at Springfield, One series
of 100 varieties, collected on June 23 and examined recently, yielded
ouly 7 varieties with less than 100-percent infestation, and these were
probably escapes. Heavy infestations noted in several fields in the vicin-
ity but apparently no commercial damage was sustained,

A WHEAT JOINTWORM (Harmolita vaginicola Doane)

Massachusetts, F, W, Poos (August 24); Collected in wheat stubble at Lenox
today. Not previously reported from Jiassachusetts, according to our
records,

CORN • .

CHINCH BUG (Blissus leucopterus Sny)

Indiana, C, Benton (September 18); Hot, dry weather late in August and early in
September very favorable to second— brood development. By September 16
about half the bugs had become adults, and most of the remaining nymphs
had reached the fifth instar. Many cornfields show from moderate to heavy
infestations, but no serious damage reported. Considerable migration from
corn to winter quarters observed from September l4 to I7.

-U90-

Illinois. W, P. Plint (Septeml^or 23): Dry weather late in August and in
September has permitted the development of late-hatched chinch hugs,
Appa.rontly large numbers will go into winter quarters in central Illinois,
but it is too early to say how heavy the hibernating population will be,

Missouri, L, Haseman (September 26); Reports and surveys during September in-
dicate that throughout much of the grain-growing section of Missouri there
will be a very heavy carryover of adults. Complaints frorm parts of north-
ern Missouri indicate that they were abundant, enough in the late corn to
affect seriously the maturity of the chop, whore their injury was combined
• with the effects of drought,

Nebraska, M, H. Swenk (September l4) ; _ Inquiries and complaints received from
Jefferson, Lancaster, Sarpy, and' Douglas Counties during the period
August 17 to September 8, inclusive. The Jefferson County report indicated
them as damaging grain sorghums j in Lancaster County they were heavily in-
festing ground that had been in corn or sorghum; while in Sarpy. County
corn, Sudan grass, and oat and wheat stubble were found to be infested,

Kansa.s, H, R, Bryson (September 25)* More abundant in the eastern third of

Kansas than for some time. Adults flying in abundance on about September
15, Indications are that a larger number will go into winter quarters thaij
for a number of years, ,

EUROPEAN COHN BORER (Pyrausta nubilalis Hbn. )

Massachusetts, A. I, Bourne (September 22); Throughout much of the eastern part
of the State they have caused less damage than normal. \ln western Massa- j
chusetts, particularly in the Connecticut Valley, both the first and secord:
broods were very abundant and caused heavy losses, especially to sweet
com, !

M, M, Cole (September 5): Several fields of sweet corn at Vineyard
Haven, Martha’s Vineyard, sho’^ed broken stalks and tassels but the attack
did not affect the yield to any great extent. ^

Rhode Island, A. E, Stene (September 20): Somewhat more abundant than in previ-
ous years .

Indiana, E, V, V^alter and D, W, La Hue (September 2l): A count of 200 stalks , of
late corn in a field near La I^iyette showed 6,5 percent of the stalks in-
fested, The first 5 infested stalks were dissected and 12 larvae found.

In another field of late sweet corn, 22 infested stalks were found in 'J)00 I
examined, 19 borers being found in 5 stalks,

CORN LANTERNELY (Peregrihus maidis Ashm, ) |

North Carolina, C, S, Brimley (August 3l){ Heay;;’ infestation on corn at Castle '
Hayne, Nevr Hanover County, in the southcartern part of the State.

COEIT LEAP APHID (Aphis maidls Fitch)

Utaii. G« F. Knn-'ltnn (August 3l) ; Some corn plonts o,t Greenriver heavily in-
fested.

A RED SPIDER (Acarina)

Utah, G. F, Kno’^lton (August 3l)! Some small patches of sveet corn destroyed

hy rod spider at Greenriver; other fields in Emery County from lightly to
moderately infested. In one large field of field corn, 25 percent was
rather severely injured. Also injuring corn near Logan, Cache County,

ALFALFA

ALFALFA WEEVIL (Hypora pos tica Gyll,)

California, A, E. Michelhacher (Septenh- r 23): Both larvae and adults collected
in the infested part of the San Joaquin Valley throughout the summer. The
average number collected per 100 sweeps of a net on September 22 for the
different fields ranged from 0 to 13 larvae and from 0 to 17 adults, No
specimens taken in the Pleasanton region, and in the country adjacent to
the San Francisco Bay the larval count ranged from 1 to, 6 and the adult
count from 0 to 2,

alfalfa C.ATEEPIL.LAR (C olias eurytheme Bdv, )

California, A. E, Michclbacher (September 23): During the latter part of August
larvae did considerable damage to alfalfa in several fields in the north-
western part of the San Joaquin Valley, Serious loss. restricted to the
area near Westley, At present scarce in all fields,

SORGHUM

A WEEVIL (Anacentriaus deplanatus Csy. )

Kansas, H, R, Bryson (September l); Found for the first, time attacking sorghum
in Kansas. Discovered when it destroyed practically an entire row of
sorghum in nursery at Mariiatt.an. Twenty beetles reared fro'' the larvae
taken from the stalks. Also reared from b,'^rny'''rd grass* (Det, by L. L.
Buchanan, )

SUG/ulGAHE

SUGARCjUIE borer (Piatraea saccharalis F, ) „

Louisiana, J, W, Ingram ;uad E. K. Bynum. (September 25): Numerous dead- sugarcane
tops apparent in fields. These observations, infestation counts, and re-
ports of unusually heavy infestations in seed cane, which is being planted,
indicate that damage nay be as heavy, or he-'vier^ than in 193S»

RICE

RICE STALK BORER (Chilo pie. jade litis Zinck. )

Louisiana, W. A, Douglas (ScpteriLer l6); In a survey of the rice section, 2,4
percent of all rice stalks were found to have white heads caused hy this
horer and hy the sugarcane "borer '(D, saocharalis). Some fields had as higl

as 6 percent 'pf ^'hite heads, fr6m which ho grain was produced,

«

Texas, W. A, Douglas (Septem"ber l6):' The -percentage of v'hite heads caused "by

this "borer and the sugarcane "borer in Texas r icefields was found to aver-
age 2,3 in a survey of representative fields, Injurj'- of this type reached
as high as 20 percent in a field near Katy, Harris County, southeastern
Texas,

E,R U I T I N'S E C T S ■

pupating by Angus t 20, Only' a few adults captuped in "bait traps after
September 1, ■

Virginia, A. M. Woodsido (September 23); Elit^ht of first-brood adults continued
from late in June until the first week in September, Infestation heavy
in central Virginia,

Tennessee, G, M. Bentley (August 29): The. second bro^d has been serious in i
the apple-growing areas of the State,

Indiana, L, E, Steiner (September 22); In most orchards in the Vincennes area
the number of second-brood adults that' came to bait traps duping the peak
of activity, August 24 to September 5i was less than during the first-broodi
peak in mid-July, Infestation well above normal, and an unusually heavy j
'carry-over is anticipated,

Missouri. L, Haseman (September 26); Third-brood moths and larvae picked up in
ab-ondance in practically all sections of Missouri, In central Missouri
most of the larvae are approximately half grown.

-^93-

Washington, E. J. Newcomer (September 1^): Somewhat more ahundant than usual

in the Yakima Valley on apple and pear, owing to continued hot weather in
Augus t ,

YELLOW-NECKED CATEEPILLAR (Da tana ministra Drury)

about 25 or 30 miles northwest of Goshen,

APPLE LEAFHOPPERS (Ci cade 11 idae)

Massachusetts, A, I. Bourne (September 22); Apporently somewhat less abundant
than last year, and the infestation over the State seems to be spotty.
Generally it would be considered lighter than normal,

Virginia, A. M, Woodside (September 23): Common in many apple orchards. The
white apple loaf hopper (Typhlocyba pomaria McA, ) is generally the most
numerous but in some orchards Erf~throneura hartii Gill, is more abundaat,

Georgia. 0, I. Snapp (September 20): Jarring records show a cons idorahle in«

crease in adults in peach orchards at Port "Valley, central Georgia, during
the period August 21-28, owing to the emergence of second-generation in-
dividuals from the soil. Infestation heavier than that of an average year
Most of the adults have left the trees for places of hi"bernation. Popula-
tion in hi"bernation at the "beginning of the 1939-^0 season heavier than
average,

ORIENTAL ERUIT MOTH ( Grapholitha moles ta Bus, ck)

Massachusetts. A, I, Bourne (Septem"ber 22); Reports indicate that on^early

peaches, ^ron wormy apples collected in this orchcird late in August, 2,150
moths have emerged. Abundance throughout the sear. on, about 10 percent of
the total catches being made in. May, suggests that this pest can readily
develop from year to year on nothing but apples,
