CEREAL AND FORAGE-CROP INSECTS 
WHEAT 
HESSIAN PLY ( Phytophaga dest ructor Say, ) 
Indiana |f>. J Davis (September 14). "The Hessian fly situation is unchanged. 
The farmers are urged to delay sowing until af i-.er the "fly-free" dates 
and, from the inquiries received and the general sentiment throughout 
the State, universal adoption of this practice this year is anticipated'.' 
Illinois W. P. Flint (September 19). "Booont surveys shwsri flaxseeds slightly 
less abundant than usual, except in a few of the niid --western counties. 
Here there is a moderately heavy infestation. A little more than 
50 per cont of the flaxseeds- are. parasitized. No indication of second 
or supplementary fall brood." 
Nebraska M, H. Swank (September 15). "The. distribution of the Hessian fly 
seems to be very local as to menacing abundance. The pest did not 
increase in numbers during the summer to the extent that was threatened 
earlier in the season. Nevertheless many farmers are sowing late to 
avoid possible injury by this insect." 
Kansas E. G. Kelly (September 22). "Our summer survey indicated a very light 
infestation in ecst Kansas, Rains throughout the State in August ani 
early September produced a good crop of volunteer wheat. The volun- 
teer wheat, however, is very little infested." 
FALSE WIHEWORM (Elcolcs spp. ) 
Kansas E. G. Kelly (September 22). "The larvae of this insect are doing 
considerable damage to early sown wheat in some of the western counties 'J 
CORN 
CHINCH. BUG ( P.lissus lquco pteru s Say) ,;. 
Indiana J. J. Davis (September 14). "ihe chinch bug is probably the most 
conspicuous and most talked of pest in Indiana. Following the summer 
flight of matured bugs it dropped out cf sight, so far as the farmer 
was concerned, but they are again reporting a great abundance of the 
bugs in corn, not only where it was observed. Inst summer but in many 
new localities. The heavy rai-s, no doubt' 1 , destroyed, large numbers 
of the bugs but the check was not sufficient to control the pests. 
Corn has been badly damaged by the second brood of bugs in some lo- 
calities, although this second-brood injury J"? not as widespread as 
anticipated because the corn was sufficiently advanced ^o overcome a 
considerable amount of injury and the hea^y rains apparently hafce 
assisted."
