- 40 - 
percent of plants infested. A few adult ladybirds observed. Report re- 
ceived of considerable abundance on oats in Harper County. 
H. R. Bryson (April 25): Notes show presence on winter barley in Cher- 
okee County on November 11, 1941 » in Cowley and Sumner Counties on April 
11, and in Kingman County on April 14. . Reported as observed in Sedgwick, 
Sumner, Harper, Barber, Comanche, Clark, and Ford Counties. Reported also 
that infestation in Harper, Barber, and Comanche Counties had apparently 
disappeared, although damage was still evident. 
Oklahoma.. F. A. Fenton (April 23): Severe infestation, in. southern third 
of State; most of the barley and oats destroyed and half the wheat in 
some areas, where fields were generally infested. Infestation spread 
northward, involving small grains as far north as Stillwater, but injury 
was not so severe in this area because wheat was more advanced; however, 
most of the barley was destroyed or severely damaged. At about this time 
heavy rains over a considerable part of the northern Wheat Belt resulted 
in an apparent check in infestation. Recent survey showed wheat in excel- 
lent condition, the only fields infested being barley. 
Texas. P. B. Dunkle (April 8): Fall-planted oats on lighter soils destroyed 
as early as January, and by March 1 practically all fall .and .spring oats 
had been destroyed from Gainesville to Corsicana, and from McKinney to 
Henrietta. Barley and wheat were then attached, and by .April 1 all but a 
very few isolated borderland fields were destroyed. Infestation now very 
heavy as far west as Brownwood, Brown County, and as far north as Amarillo, 
Potter County. 
F. L. Thomas (April 20 )» Serious injury in north-central Texas from 
San Angelo, Tom Green County, and Waco, McLennan County, northward to the 
Red River. Injury especially heavy in Dallas and adjoining counties. 
CHINCH BUG ( Blissus leucopterus Say) 
Indiana. C. Benton (April 28): Observations on flight screens showed that 
a few bugs had left winter quarters at LaFayette on April 5 and 6. Second 
wave of gradual migration from April 15 to 28, peak occurring from April 
23 to 25* Indications are that most of the bugs left . hibernation earlier 
than for several years. 
Illinois. W. P. Flint (April 23): Moderately heavy flights are occurring 
on warm days. 
Iowa. H. E. Jaques (April): Moderately heavy infestation in west-central 
and southwestern Iowa; less heavy in southeastern part of State. 
Missouri. P. C. Stone (April 1): Recent surveys in central Missouri show 
winter mortality in some individual clumps to be as high as 30 to 40 per- 
cent, though the average will be much lower. Activity observed in clump 
grasses during the warm period ended March 25 > but no flights observed. 
(April 24) : Considerable activity observed in hibernation quarters in 
central Missouri during the second week in April. Bugs were, flying in two 
southwestern counties April 17 and in northwestern counties April 23. 
Nebraska. H. D, Tate (April 15): Survey during the last week of March and 
the first week of April showed an average winter mortality in the east- 
central and southeastern counties of approximately 20 percent, somewhat 
less than normal. , • 
Oklahoma. R. G. Dahms (April 24): All had apparently left winter quarters 
by April 8, as none were found in clumps of bunchgrass; many bugs observed 
flying north on April 16 and 17. Reports received of destruction of young 
corn plants in Comanche County. Cool, wet weather has retarded oviposition
