The scouting work revealed no extension of the range of the corn "borer 
except in the following counties which are in every case adjacent to areas 
previously Imown to "be infested: Hamilton County, Ohio; Somerset County, Md.; 
Sussex County, Del.; ■Cumberland pounty, N. J.; and Northampton County, Va." 
In addition to the marginal survey, a less detailed reconnaissance survey 
was conducted in Wisconsin, Illinois, Kentucky, West Virginia, and Virginia, 
outside the present ]aiown limits of infestation, No new infestations were 
found. (P. N. Annand, Bureau of Entomology and Plant Quarantine, U. S. D. A.) 
C03N EA2 IV02M 
During the third week in April the corn ear worm appeared in central 
and southern Florida, southern Louisiana, and Hidalgo County, Tex, By the 
middle of June heavy damage was being reported from the Carolinas tc southern 
Iowa and Kansas, Early in July larvae appeared in southern New York and Con- 
necticut. Serious damage was already being done to sweet corn and field corn 
in the East Central States. There was probably more damage by this insect 
in the upper Mississippi Valley than there has been for many years. The in- 
sect ras not so destructive in the northeastern part of its range as it was 
last year. 
ABMYWOESE 
Early in June heavy flights of the armyworm were observed in Indiana 
and Illinois. As the month advanced, light outbreaks were reported from 
Illinois and severe outbreaks from \7isconsin, Minnesota, and Iowa. In August 
the worst outbreak of many years occurred in southeastern Minnesota and north- 
central Iowa. 
G-BESN BUG 
Late in February the green bug appeared in Kingfisher and Alfalfa Coun- 
ties, Okla. In April the aphid became numerous in wheat, barley, and timothy 
in southern Missouri and was reported as destroying wheat in southwestern 
Nebraska and throughout the wheat-growing sections of Kansas and eastern Okla- 
homa and the eastern half of Colorado. By the middle of May over 22,000 acres 
of wheat were a total loss, 50,000 more were danaged in Oklahoma, and 21,000 
acres of oats were completely destroyed. 
WEBWOEMS 
Two species of webworms, Loxostege sticticalis L. and L. commixtalis 
'ialk. , appeared in unusual numbers from Minnesota and North Dakota southward 
to Nebraska, Kansas, and Colorado. Very heavy flights of moths were observed 
during May. Larvae became very abundant in Minnesota and North Dakota during 
August. Larvae of L. sticticalis were so numerous in Frontier County, Nebr. , 
that where migrating individuals crossed railroad tracks, they imoeded the 
movement of freight trains. Crops were considerably damaged in Kansas and 
Nebraska. The garden webworm (L. similalis Guen. ) was re-orted as damaging 
alfalfa and soybeans from Ohio to Iow a , Missouri, and Nebraska.
