J. J. Davis (August 16). "The Hessian fly is sufficiently 
abundant in all parts of Indiana to call for special efforts on 
the part of the entomologists to secure universal cooperation in 
sowing wheat after the fly-free date, a poster is being issued 
and sufficient publicity \-i 11 be given through newspapers and 
county agents to insure a maximum cf cooperation, In this cam- 
paign the entomologists of the State are having the assistance 
and cooperation of the Federal entomologists located in the ter- 
ritory." 
Illinois W. P. Flint (August 18). "Throughout the greater part of the State 
puparia are scarce in tike whe t stubbie* There are a few of the 
western counties along the Mississippi River where flies are 
abundant. 
Oregon L. P. Rockvood (August 13). "There has been more lodging of wheat 
in the Willamette Valley in fields moderately infested by Hessian 
fly than usual. This is attributed to the prevalence of strong 
northwesterly winds during July. One farmer reports as much as 
one-third of his crop lodged*." 
WHEAT MIDGE ( Contarinja tritici Kir by) 
New York G. E. Smith (July 16). "This insect is quite plentiful in Orleans 
County."
