HESSIAN ELY ( Phytophaga destructor Say) 
Ohio. T. H. Parks (Anril 2H) : The hessian fly infestation is very low and 
no visible damage is expected in any part of the State. 
Indiana. W. B. Noble (April 19): Spring emergence of the hessian fly is late. 
A dissection of overwintered puparia from volunteer wheat at Lafayette 
showed 35 percent to contain white to pink pupae. Very few eggs present 
on young wheat. (April 23): A dissection by H. R. Painter showed 63 per- 
cent of puparia from volunteer wheat near Lafayette to contain white to 
red. pupae. About 3 percent showed emergence of adults. 
Illinois. C. Benton (April 15) : White to red pupae present in volunteer 
wheat in Christian County, central Illinois. 
Missouri. L. Haseman (April 27): Except for a few areas, the hessian fly isnot 
particularly alarming this spring. The worst center, according to our 
observations, is on the east side of the State, particularly in the 
northeast part, where some heavily infested fields have been found. 
Kansas. H. R. 3ryson (April 22): Wheat fields in the western part of the 
State are practically free of infestation. In one field near Junction 
City adults were laying eggs. 
CHINCH BUG ( Blissus leucopteru s Say) 
Ohio. T. H. Parks (April 2'-0*. A survey made in eight counties from April 20 
to 23 showed chinch bugs abundant in clumps of volunteer timothy in many 
localities. The heaviest infestation was found in Wyandot County, north- 
central Ohio, though this may not be the center of the infestation. 
Counts revealed from none to 206 overwintering bugs per square foot of timo- 
thy clump, depending on the locations visited. The average number per 
square foot for '43 examinations is 25 bugs. This is 12 times as many as 
were found in a similar survey during the spring of 193&. Dry weather 
will undoubtedly bring trouble. 
Indiana. J. J. Davis (April 26): Chinch bug abundance is anticipated along 
the western border of the State from Lake County to Greene County and 
extending into the interior for at least two tiers of counties. 
Illinois. C. Benton (Anril 17): The weather has been cold, except during the 
past few days, when maximums have reached 76~88 n F. Observations near 
Taylorville , Christian County, in central Illinois, on these days showed 
the bugs to be restless and numbers moving around among the bunch-grass 
clumps, but most of thorn still rather inactively hiding in the clumps. 
There may have been some migration on these days, notwithstanding the 
rather stiff wind prevailing, although casual observations in small 
grains have shown no bugs yet.
