HESSIAN FLY (Phy t cvphaga destructor Say) 
W, P. Flint: Examinations made during the past week in 
southern and central Illinois failed to show any emergence 
of the fly up to April 10. 
L. Haseman (April 23): Some interest is developing in the 
possible damage from the spring brood of the Hessian fly* 
Generally speaking, however, the fly situation except in 
restricted 'local it ies is less threatening in Missouri than 
a year ago. 
M« H. Swenk (April 21); Regarding the Hessian fly in Nebraska, 
there is little to add to my rather full statement dated 
March 12, except that a subsequent personal survey of the 
area of heavy infestation in Furnas County reveals the fact 
that the heavy midsummer brood of 1923 that developed in the 
volunteer wheat still largely persists there in the puparium 
stage, and these puparia, together with those of the main 
fall brood in the early seeded winter wheat, will undoubtedly 
form a heavy spring brood of flies. Flies were already be- 
ginning to emerge in small numbers during the third week in 
Apr il . 
J. W, McColloch (April l6): A trip through western Kansas 
last week indicated that, following the abnormally high 
rainfall of last fall, the Hessian fly is far above the 
average in abundance in the region in northwestern Kansas 
extending from Smith, Osborne, and Russell Counties westward 
to Thomas and Rawlins Counties-. Another center of serious 
infestation seems to be located in the counties surrounding 
Riley County, at the time of this survey from 5 to 75 P er 
cent of the grain was infested. 
CHUTCH BUG- (315-ssus leuc orterus Say) 
~. r . P. Flint: The weather of April has been favorable to this 
insect. On April l6 some bugs were observed flying in the 
central Illinois counties. There has been no general movement 
out of winter quarters up to the present time, April 19- 
L. Haseman (April 23): In central Missouri scattering flights 
of chinch bugs were observed between the 10th and 15th of 
April. The chinch bug situation looks threatening in spite 
of severe winter, and farmers are preparing for another chinch 
bug combat*
