HESSIAN FLY (Phytor-haga destruct or Say) 
C. C. Hill: Surveys of the principal wheats-growing 
regions of the States of Hew York, Pennsylvania, Maryland, 
Delaware, and Virginia show a very low infestation from 
the Hessian ..fly throughout these regions. For a number 
of years the prevailing practice in these sections has 
"been to sow wheat after the fly-free date, and there is 
every evidence that the present light infestation of the 
fly is due to this policy. Although the fly is universally 
present in small numbers, yet even the early sown fields 
showed very light infestation. 
Thomas J. Headlee (Letter dated January 16,1926): This 
insect is not sufficiently abundant in this State to 
threaten injury. 
W» J. Schoene: We have no- recent reports on the Hessian fly. 
W, B. Cartwright: All available records show no infestation 
of the Hessian fly to wheat sown after the recommended 
dates. ■ In most of the localities represented by the survey 
it appears that the wheat could have been drilled a few 
days earlier than the safe seeding dates. However, in 
locations from which egg' deposition records supplemented 
the other fly records, infestation by fly eggs occurred 
on the sowings just prior to these dates, whereas later 
records showed no resultant larval infestation. The 
inference is that the young larvae ?;ere killed by the freezes 
and hostile weather conditions of October. 
Infested volunteer wheat in stubble and fallow -fields 
has formed a basis at least for a minor spring brood of 
flies, but no damage is foreseen. In the fall wheat sowings 
the fly is at a low mark but unfortunately the adverse 
season for seeding wheat and the possible winter kill to the 
delayed sowings in the northern section have overshadowed 
the success against the Hessian fly. To date there has been 
no evidence of winter kill oST wheat plants or retardation 
of growth. 
K % Garman: I have had no complaints of the Hessian fly 
recently and from all indications it has been rather 
scarce in this State.

R. H. Pettit : The Hessian fly seems to be present in small 
numbers exaept that in three localities it seems to be 
fairly plentiful. Albion, Kalamazoo, and Battle Creek 
showed moderate numbers here and there this last fall. 
During the spring we examined into the situation in quite 
a few counties and encountered them only in the districts 
named. 
C. L« Fluke: The Hessian fly has now become quite generally 
distributed over Wisconsin, but is very seldom a severe 
pest. During the fall of 1923, conditions were ideal for
