HESSIAU FLY (Rhytopbaga destruct or Say) 
T. H. Parks (July 25): The results of the wheat insect survey 
show that the Hassian fly is -under control in all Vat a few cen- 
tral and west-central counties. The highest infestation found 
was 28 par cent of the culms in Darke Coi-aty, western Ohio. The 
average infestation for the State is ? per cent compared with 11 
per cent in 1934. 'The greatest decres-sr, in infestation has been 
in northeastern counties where there is low only a trace present. 
C. J. Drake (July 9): During the latte: 1 part of June Fred D, 
Butcher, Es&ension Entomologist, ixia.de a mrvey of the winter-wheat- 
growing district of Iowa. Special efforts were- made to examine- 
early Deeded fields. In sever. 1 cases t few flaxseeds' were found 
in these fields but practically no commercial damage was observed. 
Reports fro;:: various county agents indie it e that the Hessian fly 
loss for the IS35 wheat crop will be practically nil. In Mills 
County one field drilled 10 days before ;he safe-seeding date 
showed an infestation of 4 per cent. A field of colunteer wheat 
in Polk County, the only field examined jy che county agent and 
Mr, Butcher that contained the Hessian f j.y, showed an infestation 
of 6 per cent-. In southeastern Iowa cezeral fields drilled a 
few days before the safe-seeding date shewed an infestation of 
from 1 to 6 per cent. he fields have b »&a badly damaged by the 
Hessian fly. Over 90 per cent of the farmers of the winter-wheat- 
growing portion of the State cooperated :n the Hessian fly campaign 
in the fall of 1924. 
J. 7.\ I.IcColloch (July 21 ): There is no question but what the 
Hessian fly was responsible for a large jart of the poor wheat 
crop in Kansas. From reliable information and from personal 
field surveys, we are safe in saying that thousands of acres in 
the State were abandoned before harvest aid that where the -..heat 
was not abandoned the loss varied from 5 sushels to, in some cases, 
10 bushel.-', per acre. Stafford County estimates the loss due to 
the Hessian fly at 1,250,000 bushels. T.i the fields about Riley 
County it has been found that the fly reduced the crop at least 
50 per cent, 
1THSA.T STEM MAGGOT (M- sromyza americana Fitch) 
Sowa C. J. Drake (July 9): The wheat stem maggot is rather abundant 
over practically the entire winter wheat growing area of the State. 
Records indicate that this insect is doing more damage to winter 
wheat than the Hessian fly this year in Iowa. 
South DaHrota H. C. Severin ( July 2$>): The average number of wheat stem maggots 
are with us again this year over the State on wheat, barley, and
