INSECT ? EST. SURVEY BULLETIN

OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES EOR SEPTEMBER, 1931. 
The grasshopper situation had not materially changed during the 
fore part of the month; during the latter part of the month, however, damage 
dropped off rapidly and egg, laying started. 
The first specimens of the cotton leaf worm were observed in southern 
Mississippi on August 31. This is so late that there is little probability 
of any damage to fruit in the Northern States. 
The common red spider continued to be troublesome throughout the 
month over practically the entire country, 
A new and heavy infestation of the Japanese beetle was found at 
Springfield, Mass. This insect was also reported as having been taken at 
Charleston, S. C, at several localities in Somerset and Worcester Counties, 
Md., at Richmond, Va. , and as far west as Pittsburgh and Erie, Fa. It has 
also been found this summer at Little Falls, Wa thins Glen, Eort Edwards, 
Albany, and Buffalo, N. Y., and at Boston, Mass. 
In this number of the Survey Bulletin is a report on the wheat 
survey which has just been completed in Illinois. The State average of 
tiller infestation for this year is 9 per cent as compared with 12 per cent 
in 1930. There is also in this number of the bulletin a detailed report of 
the wheat joint worm situation in Illinois. 
A chinch bug outbreak in Charleston, S. C, caused very extensive 
damage to St. Augustine grass lawns in that city. Weather during September 
as a whole was favorable to chinch bug development in the East Central 
States and rather large numbers of these insects will in all probability go 
into hibernation this fall. 
The green clover worm quite seriously infested soy beans, cowpeas, 
and clover in the vicinity of Chadbourn, N. C, and in south-central Tennessee. 
The alfalfa weevil did more damage than ever before at Casper, Wyo. 
In some fields the foliage of the first cutting was practically destroyed. 
The three-cornered alfalfa hopper did very appreciable dm age to 
alfalfa in fields along the Mississippi River in Bolivar and Washington 
Counties, Miss., and from Madison County to East Baton Rouge County, La.
