HESSIAN FLY (Phyto phaga des tra ctor Say) 
J. J. Davis (July 22): Further observations on the Hessian fly 
corroborate our statement in the last Bulletin to the effect that 
we may anticipate injury in early sown fields of wheat this fall. 
L. Haseman (July 20): Stubble counts show following infestation: 
Springfield, 2 per cent; Columbia, l/2 per cent; Charleston, 17 per 
cent; Maryvilie, 13 per cent; Cuba, 2 per cent; St. Louis, 13 per 
cent. An epidemic threatens. Control campaigns are being pushed. 
M. H. Scenic (June 15- July 10): The wheat harvest, now in full 
swing in southeastern Nebraska, indicates that on the whole a good 
yield will be realized, notwithstanding the fact that the attack 
of the Hessian fly last fall destroyed completely a considerable 
acreage of wheat and materially thinned the stand of a larger acre- 
age, while during the past May and early June the fly, in connection 
with unfavorable weather conditions, caused short and often only 
partly filled wheat heads to be the rule. It is generally realized 
that the present wheat crop would have heeh much better if the fly 
had not made this serious double attack upon the plants. Continued 
efforts will be made to increase the percentage of farmers that will 
await the fly-free date this fall and thus decrease fly injury on 
the next crop of winter wheat. 
J. W„ McCoIloch (July 19): The severe Hessian fly infestation, 
which I reported from western Kansas during the winter, took a very 
big tr a, and the farmers in that section consider the Hessian fly 
a blessing rather, than a pest. Conditions for seeding last fall 
were exceptionally good and a very heavy stand of wheat was secured 
The Hessian fly also being abundant killed out a good part of the 
stand, and at the time, looked as though, it had ruined the prospects 
for the wheat crop. This spring, however, the plants tillered out 
and at the time the fly was emerging, dry weather set in and proved 
fatal to the eggs, and there was very little further infestation 
this spring. Dry weather continued until harvest time, and the 
farmers claim that if the fly had not reduced the stand last fall 
the amount of wheat on the ground would have been too great for the 
available moisture supply. As it was, with the reduced stand, 
there was sufficient moisture for the crop and western Kansas is 
rolling in wealth at the present time. It is going to be very 
difficult to go into this country and talk Hessian fly control 
measures at the present time. (July 22): The data on the average 
acre loss has been furnished by E. C. Pal ton as follows: A loss 
of 6 bushels per acre is estimated in southeastern Kansas in Craw- 
ford County with 5 bushels loss in adjoining counties of Neosho and 
Cherokee. A region of 4-5 bushels loss is also located in east- 
central and northeastern Kansas, extending from Republic and Morris 
Counties east to Franklin and Drown Counties with a third similar 
region recorded in the northwestern and north- central part of Kan- 
sas, extending from Decatur and Wichita east to Mitchell County.
