CEREAL AND EORAG-E-CRO? INSECTS 
WHEAT 
HESSIAN ELY ( Phytophaga destructor Say) 
Ohio, T. H. Parks (July IS): The annual wheat insect survey by the Ohio 
entomologists just "before harvest showed the average infestation of the 
straws to he I5.5H percent, as compared with 8.1 percent in 1933- Thirty- 
four wheat counties Wore visited and 10 to 12 fields were inspected in 
each county. County infestations ranged from 2 to U6 percent. Nine- 
teen counties showed marked increases, 1 showed decreases, and in 8 
the percentage of infestation remained ah out the same as in 1933* ^- iC 
insect has increased most in the northwestern quarter of the State. 
Considerable lodging of straw occurred in Wood, Seneca, Sandusky-, and 
Huron Counties. The most heavily infested fields were in Wood County, 
where three fields each average 70 percent infestation. All of them 
were sowed 2 or 3 days before the safe-sowing dates. In many fields 
sowed after the safe-sowing dates the infestation averaged between 30 
and 50 percent. No serious damage was caused by the fall brood, the 
great increase being due entirely to the spring brood. 
BLACK GRAIN-STEM SAWFLY ( Trachelus tabidus Eab.) 
Pennsylvania. E. J. Udinc (July): An outbreak occurred in the counties 
of Indiana, Armstrong, Butler, northern Westmoreland, Allegheny, 
Mercer, Lawrence, and Beaver. 
Ohio. J. S. Houser (July~3l) : This sawfly was found in Ohio for the first 
time this year. The infestation centers in Mahoning, Columbiana, 
Carroll, Harrison, and southern Trumbull Counties, and light infesta- 
tions occur in northern Trumbull, Portage, Stark, cistern Wayne, Tuscar- 
awas, Belmont, and northern Monroe Counties. The most severely in- 
fested field of wheat had 68 percent and several other fields in the 
area of greatest abundance had 50 percent or more of the stems infested. 
One field of rye averaged l6 -percent infestation. The crop loss is 
great. (Dot. C. C. Hill) 
CORN 
CHINCH BUG ( Blissu s leucopteras Say) 
Ohio. T. H. Parks (July 18): The chinch bug battle over, we find that 
50 of the S>S counties required aid in controlling the insect with 
barriers. This was the worst infestation for many years, although 
very few fields of com were destroyed, good growing weather having
