CEEEAL AND FORAGE-CROP INSECTS 
WHEAT AND OTHER SMALL GRAINS 
HESSIAN FLY ( Phytophaga destructor Say) 
Ohio. T. H. Parks (June 21): Rather high infestations now present in 
some early wown fields of the northwestern part of the State. Wheat- 
insect survey, now under way, shows infestations less than 10 percent 
in southern and central counties. 
Indiana. C. Benton (June 19): Pupation of spring Brood practically 
completed near La Fayette By June 12. Several rather heavily 
infested fields observed or reported from Tippecanoe and adjacent 
counties. Several damaged fields reported from the heavily infested 
area of northeastern part of the State. Infestation due to rather 
general early seeding of wheat during the last 2 years, in order to 
escape Black stem rust infestation, which severely injured late-sown 
wheat in 1937* 
J. J. Davis (June 21): Apparently unusually abundant and 
destructive in northeastern Indiana. 
Iowa. H. E. Jaques (June): Infestation in southeastern section of 
Louisa County. 
Missouri. E. T. Jones (June 12): Appears to Be generally light and 
scattered in southwest. Some socond-spring-goneration larvae 
present on young wheat at Springfield, But not very abundant. 
Nebraska. M. H. Swcnk (June 20): Has done commercial damage to wheat 
in some localities along .the southern Border of the State west to 
Jefferson County, and along the Missouri River north to Burt County, 
owing mostly to an increase in very late-sown wheat By the supple- 
mentary fall Brood of 1932, carried still farther By the 1939 spring 
Brood. A field in Burt County on June l4 showed an average of 
Ch83 puparium per stem, including Both the supplementary fall Brood 
of 1932 and the spring Brood of 1939 - 
Kansas. E. T. Jones (June 12): Examination of spring stubble from 32 
fields distributed over central and southern parts of the State^show 
puparia of hessian fly present in most fields. Although infestations 
generally average under 10 percent of tillers, a few widely 
scattered fields show high infestations. Only occasional late 
fields show presence of second-spring-generation larvae. 
CHINCH BUG ( Blissus leucopterus Say) 
Indiana. J. J. Davis (June 21): Apparently there will Be more trouble 
than was anticipated from this post in western Indiana, from Lake 
County on the north to Knox County on the south. Bugs more immature 
than usual, in comparison with the development of small grain.
