HESSIAN ELY ( Phytophaga destructor Say) 
W. B. Noble through. C' M. Packard (May 2): Very light 
oviposition occurred from April 17 to 21. The main emergence 
apparently had not yet arrived on April 30. 
C. M. Packard (May 2): The spring infestation is expected 
to be generally light in the East Central States owing to 
small numbers of overwintering puparia and April weather 
conditions which were rather unfavorable to fly activity. 
J. H. Bigger through W. P. Flint (May 18); The Hessian 
fly is very abundant. From 32 to 45 per cent of tillers in 
certain fields were infested with eggs on April 22 in Greene 
County. 
H. E. Jaques (May 25): • The Hessian fly is moderately 
abundant in the southern half of the State. and there are 
reports of great abundance in Woodbury and Tama 'Counties. 
L. Haseman (May 23): The Hessian fly situation seems to 
be not at all serious anywhere in the State. 
M. H. Swenk (April 15 - May 15): The western limits of 
the present infestation seem to be Gothenburg, Dawson County, 
in the Platte River Valley, and a little west of McCook, 
Redwillow County, in the Republican River Valley, in 
general, the winter wheat came through in good condition, 
and the abandonment this spring was very small. It is 
still too early to' tell how heavy an infestation the 
spring brood of the fly will be able to build up this year. 
H. R. Bryson (May 23): Dr.' E. G. Kelly reports on May 1 
that the. Hessian' fly, is plentiful in wheat 'grown in the 
northern tier of counties in the western half of the State. 
These comprise several excellent corn-growing counties. 
C. Benton through C. M.- Packard (May 2): Light egg 
laying occurred throughout April, the main wave, from April 
18 to 21, but not heavy. Small to mature larvae were present 
April 28; in the most heavily infested fields about 20 per 
cent of the stems are infested, two larvae to a stem. 
Oregon Agricultural College, Insect Pest Report (March): 
Eirst emergence of the spring brood of the Hessian fly 
occurred March 19.
