INSECT PEST SURVEY BULLETIN 
Vol. 18 July 1, 1938 No. 5 
THE MORE IMPORTANT RECORDS FOR JUNE 
The development of grasshoppers has "been uneven, and all stages are 
present, from the egg to the adult. Adults are mating in the southern part 
of the infested territory. Despite the effect of cool, rainy weather, 
which killed many young nymphs, the number surviving and individuals that 
hatched later makft tjp great populations over the entire infested territory. 
The rains may prove beneficial by producing succulent wild vegetation, 
affording food for the hoppers and preventing them from severely injuring 
cultivated crops. 
The Mormon cricket is occurring in great abundance and is extending 
its depredations farther eastward than before, injuring crops in Nebraska; 
however, inclement weather has delayed development of the pest and the 
actual damage to crops, especially in the Rocky Mountain region, has bocn 
less extensive than in 1937 • 
Owing to the prolonged cool, rainy weather, cutworm damage continued 
later in the season than usual. 
The armyworm outbreak in the Mississippi and Ohio Valleys has largely 
subsided; however, rnoths are abundant farther north, around the Great Lakes, 
A disease evidently played an important part in the control. 
Although weather conditions have been unfavorable to chinch bug 
development , isolated areas of infestation, from moderate to severe, are 
found throughout the chinch bug belt. 
The hessian fly has multiplied greatly and, although damage to the 
wheat crop is moderate, the population in many localities may be sufficient 
to menace the crop to be planted this fall. 
The corn ear worm is occurring in usual abundance in sweet corn 
and tomato over most of the South. Farther north, in Illinois and New 
Hew York, infestation is occurring a little early.
