sian fly, and attack the wheat. Besides, the wheat, for best 

 results as to soil conditions and rotation, should have been 

 seeded at the close of the preceding winter to clover or grass. 

 Also, the insect can feed and breed in the grasses surrounding 

 the field. 



Instead of following the Bureau's plan in this and other 

 cases by trying to control the insect by producing conditions 

 as unfavorable for multiplication as possible by the destruc- 

 tion of food plants, it will be found infinitely better to fight 

 the insects by the use of a trap patch, same as described for 

 the Hessian fly, and, if necessary, by attacking the hibernated 

 adults as they ovjposit on' the young wheat in the spring with 

 a multiple torch. Such use of heat is the only contact in- 

 secticide cheap enough to be used on a grain or forage crop. 



Upon the issuance of my Circulars No. 155 and 156, Hon. 

 Gilbert N. Haugen, Chairman of the House Committee on 

 Agriculture, had been asked to guard the interests of the pub-i 

 lie by having the Department of Agriculture define its position 

 in regard to the points at issue. If the Department of Agricul-j 

 ture mad any reply of any kind, I have not heard of it.
