Kansas J. W. McColloch (Sq3tember 25): A preliminary survey of the Hessian- 
fly condition in the northern part of Kansas Ijas just been completed. 
There was very little infestation by the fly in this area last soring, 
and the Survey which has just been completed shows that the adults are 
just emerging. A few eggs were found on volunteer ^heat in most of the 
territory covered. Conditions have been very favorable for volunteer 
wheat, and as a result there is lots of it in the State. Farmers are 
also planting early this year, and in many cases are not making ary 
effort t« destroy volunteer wheat. In other ^ords, conditions are very 
favorable for a strong comeback on the part of the Hessicn fly, anil* 
is going to be: interesting to follow the situation through. The most 
striking part of the ' survey this year was that the fly was present in 
the so-called reservoirs or hold-over spots which Prof. Dean described 
in his article in the Journal of Sconomic Entomology three or four 
years ago.
