The following, table indicates the percentage of 5.nfestation in 
the counties surveyed. The same counties surveyed last year and 
in 19~U were again surveyed this year,, In_192U this region showed 
5.9 P e ** cent infestation in x92; r , the info rt at ion .dropped to 1*5 
per cent, and this year it rose again to 3-6 per cent.

Ohio To H» Parks (August 17) - ^as annual wheat insect sux-vey covered 
29 of the principal wheat-growing counties, Wheat yields were 
the highest in many years B The Hessian fiy did little damage. Pour 
counties had less than 1 per cent of the straws infested. The 
average infestation for 11 counties in northern Ohio was 4 per 
cent. This represents nc increase over 1925, South of Columbus the 
insect has decreased since last year and the southern third of the 
State has less than U per cent infestation. 
The most Hessian flies during the 192b Survey were fotmd in a 
group of counties starting from Delaware on the east and extending 
westward across the middle of the State to the Indiana line. Counties 
having the highest infestation were: Delaware, J8 per cent; Darke, 
35 psr cent; Champaign, 22 per cent; Shelby. 25 per cent, and Miami, 
l6 per cent. In these counties the established safe seeding date 
held true in 1 9^5 and the infestation occurring there seems to be 
largely due to volunteer wheat and a few early-so'wn iieids. Control 
campaigns will be concentrated in this group of counties this fall. 
The average infestation for the entire State this year is 8.8 pr 
cent compared with 7. 5 P° r cent in 1925. 
Illinois W« ?. Plint (August 23): The annual wheat insect survey has just been 
completed. This year examinations were made in wheat stubble fields 
in some 50 counties in the State. A decrease in flics was noted in 
all counties with the exception of those in the northern and north- 
western parts of the State. In this area the fly is present in about 
the same numbers as in 1925. Although in no cose will the infesta- 
tion average less than 2 per cent, it is very general. Verv few
