REPORT OF THE STATE ENTOMOLOGIST 1912 35 



I to 2 up to 20 bushels an acre, an average possibly of 8 to 10, 

 the normal yield being 25 to 30. He reported all fields as being 

 infested and estimated the loss at 25,000 bushels. 



Mr H. W. Tyler, of South Byron, in early July estimated the 

 injury at 20 per cent, which he found was confined mostly to 

 number 6 and Klondike. He states that the injury was less ap- 

 parent on the better soils. The latter part of September he reports 

 a yield on his place of 16 bushels an acre, the normal being 30, 

 and adds that 99 per cent or more of the fields were infested. 

 He is of the opinion that the reduced yield was due as much to 

 winter injury as to fly and estimates the average yield for the 

 locality the past season at 10 bushels an acre. 



Mr F. C. Walker, of South Byron, reported the yield the latter 

 part of September at 8 to 10 bushels an acre, the normal being 25 

 to 30, and adds that 99 per cent of the fields were infested. In 

 his judgment, only half a crop was secured and he states that the 

 dry season of last year resulted in an abundant shelling and a 

 large amount of volunteer wheat, in which latter the Hessian fly 

 probably bred abundantly last fall. 



An examination by the writer of a number of fields in Byron 

 the latter part of June showed an extremely poor stand of wheat. 

 Many had been plowed prior to our visit, while the grain in others 

 would average only from 10 to 50 per cent of what it should, and 

 of this more or less was liable to lodge or fail to produce a full 

 crop. The large field belonging to Mr F. C. Walker was apparently 

 looking well, yet an examination resulted in finding many infested 

 stalks which will either fail to produce full heads or else are very 

 likely to lodge. The wheat field of Mr C. N. Green was one of 

 the best examined and yet there was a probability of a reduction 

 of from 25 to 40 per cent in the crop. 



Livingston county. John McNaughton, of Caledonia, placed the 

 loss the latter part of June at from 10 to 20 bushels an acre, all 

 varieties in his section being affected. No subsequent report or 

 additional data have been received from this county. 



Monroe county. Observations from the train and near Church- 

 ville and at Cold Water showed several very poor fields, most of 

 the injury being due to winter killing though some may have re- 

 sulted from attack by Hessian fly. 



Niagara county. Mr Ralph Darrison, of Lockport, stated that 

 he had talked with several farmers and none reported trouble with 

 the Hessian fly.
