slight, but that in southeastern Nebraska, central Kansas, and parts of 
Missouri the fly would do considerable damage. Over much of this 
territory voluntoor -.Theat was rank and a very considerable part of the- 
crop ^as planted before the fly-free date, 
WHEAT STEM MAGGOT , 
The wheat stem maggot (Meromyza americana Fitch) appeared in large 
numbers in Io'.7a, Nebraska, Kansas, and South Dakota, whore it did con- 
siderable damage over localized areas, 
CHINCH BUG 
The situation as regards the chinch bug ( Blissus' leucoT5terus ^y) 
is most encouraging* Throughout practically all of its range this in- 
sect is at a very low ebb. Slight trouble was observed on St, Augustire 
grass lawns in Florida and in a small wheat area in Fayette County, Texas. 
GfiEEK BUG 
Although early indications from Texas and Oklahoma presaged out- 
breaks of the green bug ( Toxoptera ^raminum Rond.) no serious trouble 
developed. Later in the season a few reports were received from part of 
the green-bug territory. It seemed to occur quite generally during the 
early summer throughout central Kansas and Nebraska, but no surious dainage 
was sustained. In October this insect was reported as being widely dis-feri- 
buted and killing patches of wheat in Benton Countyj Missouri, 
STALK BOHER 
Although the stalk barer ( Papaipema nebris. .; nitela Guen« ) was re- 
ported from over a considerable part of the Easi; Central and. West Central 
States, it was much less serious than last year and \indoubtedly would have 
attracted but little attention had it not been for the interest in corn 
insects occasioned by the advent of the European com borer» 
CORN BXLLBUGS 
Corn billbugs ( S-phenopborus spp») were unusually ab\indant this 
year in a belt extending throughout the central and western counties of 
Ohio into Indiana, northern Illinois, southern Iowa, and eastern Kansas, 
This appears to have been the worst billbug year since the organization of 
the Survey in 1921, 
CORN EAR MOm 
The year was one of almost unprecedented scarcity of the com ear 
worm ( Heliothis obsoleta Fab.). With the exception of a few reports very 
early in the season in the trucking section of the Gulf, reports from 
practically the entire Corn Belt and northward into the- sweet com areas 
indicated that but few seasons in the past could be recalled when smaller 
numbers of this insect were observed.
