26 BULLETIN 967, U. S. DEPARTMENT OF AGRICULTURE. 



The application of control measures for blister beetles must take 

 into account the relation of these insects to grasshoppers. As long 

 as the latter are present their eggs provide food for the young of the 

 beetles. The destruction of the grasshopper eggs leaves the blister- 

 beetle larva? without food, thus being doubly beneficial. Incorporat- 

 ing into the farm practice of a community the simple measures that 

 are known to hold grasshoppers in check will eliminate the danger 

 from blister beetles.
