CHINCH BUGS ( Blissus loucoptorus Say) 
Iowa. C. J. Broke (March 20 ) : Preliminary/ results of spring survey now in 
progress indicate possibility of moderate to large-scale outbreaks 
this summer. Exceptionally large numbers went into winter quarters 
last fall and from the scattered reports available it seems fairly 
certain that a, very large number survived the winter in the south- 
western a.nd we stern-central parts of the State. 
Kansas. H. R. Bryson (March 2l); Hibernating in largo numbers in the east- 
ern third of the State, Examination of bunchgrass at Manhattan in- 
dicated mortality approximating 8 percent. 
Oklahoma. R. G. Dahms (March 24): Examination of. 50 l/5~square foot samples 
of bunchgrass collected in 25 different points in Comanche County in 
March showed a total of live and 60 dead chinch bugs, or a 
mortality of only 0.8>3 percent, the lowest percentage of winter mor- 
tality in both bunchgrass and sorghum stubble for any time in the last 
5 years. 
C. E. Stiles (March 3l)* The hurried survey through the north- 
eastern section of the State during the week ended March 29 showed 
that chinch bugs were still in hibernation in bunchgra.ss; however, 
the number seems to be slightly reduced from what it was last. fall. 
No bugs were found in small grain. The weather is still cold, with 
temperatures below freezing on March 29. _ 
GREEN BUG ( Toxoptera graminum . Rond. ) 
South Carolina. W. C. Nettles (March 22): Early- -planted winter oats and 
wheat in eastern half of State considerably infested and damaged by 
spring grain aphid. 
Oklahoma. C, E. Stiles (March Jl): Th is pest has. been reported within 
the last 4g hours from the following counties: Pottawalomie, Jeffer- 
son, Logan, Canadian, Kay, and Washington, scattered throughout the 
middle third of the State from north to south. The infestation seems 
to be limited mostly to barley. Plans one under way to make a hurried 
■survey during the next few days to determine the extent of the infesta- 
tion. 
CORN 
EUROPEAN CORN BORER ( Pyrausta nubilalis Hbn.) 
Virginia. H, G. Walker (March 27): Very heavy carry-over of larvae in 
Princess Anne County. No pupae or prepupae were found in over 100 
larfae examined on March 24.
