OUTSTANDING ENTOMOLOGICAL FEATURES OP MY I921 
The chinch bug situation in the Mi ssissipx-i Valley corn 
belt is still the most serious entomological feature reported 
to the Survey. The outbreak, from present information, 
covers the north central part of Texas; all of Oklahoma 
( except the three northwestern counties and the southeastern 
prrt of the State east of a line extending from Bryant to 
Adair Counties); the six northwestern counties of Arkansas 5 
the eastern third of Kansas; southern two-thirds of Missouri 
( being worst in Jasper, Newton, and Scott Counties); touching 
south central Nebraska from Franklin to Thayer Counties; and 
southeastern Iowa from Ringgold to Louisa Counties; thence 
crossing southern half of Illinois; narrowing to a belt 
across Indiana/ extending from Vigo to Posey Counties on the 
west and Allen and Veyne Counties on the East; and ending in a 
slight infestation in the northwestern counties of Ohio, and the 
southeastern border of Michigan. 
The hessian flyrhas appeared in noticeable numbers in 
Guilford County, North Carolina, and Barnwell County, South 
Carolina r In Ohio the worst fields will probably be about 
one-half infested, and the average infestation will probably 
be much lower. In Indiana the situation is more serious, 
the insect being abundant over the southern part of the 
State as high as 59 P er cen "t of the stalks being attacked, 
and as far north as Lafayette infestation ranges from 50 to 
gO per cent e Illinois reports the outbreak as about normal. 
Missouri reports the worst outbreak since I916, in some cases 
as high as 78 per cent of the stalks being attacked. In 
Oregon there is a normal infestation, being about a quarter 
less severe than last year/ with from 26 to 30 per cent of the 
stalks attacked. 
The pale western cutworm is again present in destructive 
numbers in Montana and Colorado. In Montana it is estimated 
that from 10 to 75 P er cent of the small grain will be 
destroyed in the counties infested, and in Colorado thousands 
of acres are being plov;ed out and reseeded to a catch crop* 
The v/estern wheat-stem maggot is seriously infesting 
wheat in central Montana. The last serious outbreak of this 
pest occurred in igi8#
