Treatment: as the grubs of these beetles are known to feed on 

 the eggs of grasshoppers and are therefore beneficial, the adults 

 should be destroyed, by spraying 

 affected plants with poison or by 

 beating the insects into pans con- 

 taining water and kerosene, only 

 when necessary. 



54 Bumble flower beetle (Eu- 

 phoria ind a). Brownish mot- 

 tled beetles about f inch long 

 feeding in ears of green corn, 

 attacking peaches, etc. The young are white grubs, and may be 

 found in partially decayed vegetable matter, and the beetles may 

 frequently be seen in the spring flying and making a humming 



much like a bumblebee. This insect 

 is not usually very destructive. 

 Treatment : handpicking. 



55 Wireworms (Elateridae). 

 Cj'lindric, hard, yellowish brown 

 grubs attacking various plants, fre- 

 quently injuring planted seeds. The 

 parent insects are the brown snap- 

 ping beetles so commonly seen. 



Treatment: fall plowing. Trap- 

 ping beetles with poisoned baits. 



56 Stalk borer (Hydroecia 

 nit el a). Wilting potato vines 



may be caused by a brown, white striped active caterpillar, about 

 1 inch long boring 

 within the stems. The 

 parent is a brownish 

 moth with a conspicu- 

 ous yellow line near 

 the outer third of the 

 fore wings. This insect 

 attacks many thick 



stalked, herbaceous plants, and is a difficult one to control. 

 Treatment: burn the infested stalks before September.
