HESSIAN ELY ( Phytophaga destructor Say) 
T. H. Parks (June 24): The Hessian fly is on the increase 
after two years of comparative absence. A field of early- 
sown wheat near Columbus was found today to be seriously in- 
fested, with many broken straws. The annual wheat insect 
survey has not yet commenced but it is apparent that this in- 
sect has increased greatly since last year. 
J. H. Bigger (June 15): The Hessian fly is very abundant 
in western Illinois. Much wheat was going down in some coun- 
ties, May 21.

M. K. Swenk (June 22): The Hessian fly 'is "moderately abund- 
ant in southeastern Nebraska, though there has been no com- 
mercial damage as yet. 
H. R. Bryson (June 22): Dr. R. H. Painter reports a light 
infestation on spring wheat at" Manhattan extending west to 
Salina with a heavier infestation near Lindsborg and Lyons. 
Some fields were found in a recent trip to western Kansas 
near Hays, Colby, and Dresden, in which 100 per cent of the 
plants were infested. 
L. Haseman ( June 22) : The spring brood of larvae has caused 
comparatively little damage to wheat over most of the State, 
but the fields are generally infested, and with favorable con- 
ditions we may have a heavy outbreak this fall. 
M. M. Reeher (June 1): Some fields of spring wheat in lash-^ 
ington and Yamhill Counties show rather heavy infestations. 
Hot dry weather has prevented the emergence of the second gen- 
eration of flies to date. 
ENGLISH GRAIN APHID ( Macro si-phum granarium Kby. ) 
J. J. Davis (June 24): The wheat aphid (M. granarium ) was 
abundant and apparently destructive to wheat heads at Lyons, 
June 8. They were later reported abundant on wheat heads at 
Marion, June 20, and Rensselaer, June 22.
