Missouri. L. Haseman (February 20): Recent letters report serious damage to 
sod during the fall but local diggings at Columbia do not show many worms. 
In north-central Missouri we may have trouble. 
Arizona. C. E>. Lebert (February 19): White grubs are very numerous in soil 
of farming areas. 
CEREAL AND FORAGE-CROP INSECTS 
WHEAT 
HESSIAN FLY (P hytopha^a destructor Say) 
Missouri. L. Haseman (February 20): The results of scouting for the Hessian 
fly last fall indicate that we will probably not have any serious trouble 
this year. 
Nebraska. M. H. Swenk (Januarv 1 to February 15): The new wheat crop shows 
a varying infestation, judging from samples sent in by correspondents 
during the period here covered, the variation running from 42 percent to 
100 percent of the stems infested and the infestation varying from 0.6 
puparium per stem in a Hall County field to 4 puparia per stem in a 
Nuckolls County field. 
CHINCH BUG ( Elissu s leucopterus Say) 
Illinois. W. P. Flint (February 19): "weather conditions have been ideal for 
chinch bug hibernation, with a very high, survival in the central part of 
the State. No extensive counts have been made as yet. 
Iowa. C. J. Drake (February 19): The chinch bug is very common throughout 
the State. 
Iowa. H. E. Jaques (February 24): Southeastern Iowa is thickly sprinkled with 
chinch bugs. They are more abundant than they have been for many years, 
and our very open winter has made it easy for them. 
Missouri. L. Haseman (February 20): Much winter burning has been done, but 
the mild winter has favored the pest. Unless there is heavy spring and 
summer rainfall, the chinch bug situation will be serious. Clump-grass 
was burned February 17, with slow back fire; ore clump examined February 
20, showed 54 live bugs and 4 dead remains; within 25 feet of the burned 
clump an unburned one of like size showed 244 live and 19 dead. In addi- 
tion to an apparently large kill by burring, these figures indicate 
approximately & percent winter mortality. If the difference in count of 
the two clumps is duo to burning, it indicates a greater percent of kill 
by burning than we usually estimate. 
Nebraska. M. H. Swenk (January 1 to February 15): Among the cereal pests, 
the chinch bug was the subject of the most frequent inquiries. Daring 
the second week in February a considerable amount of winter burning was 
resorted to in southeastern Nebra.ska, where the insect is very abundant.
