 Army Worm and Moth. 



The larvae do not travel in armies unless very numerous, 

 and so often pass unnoticed. 



The first brood live as cut-worms, finally going into the 

 ground and undergoing the various stages, the moths ap- 

 pear about the last of June. In five to eight days, these 

 lay. 



The third brood emerges in the latter part of August. 



In Illinois the second brood does the greatest injury. 



They are always more numerous the year following a 

 dry year, but are never destructive and numerous in the 

 same locality for two succeeding years, because of disease 

 and parasites. 



Remedies. The tachina fly, the ichneumon fly, the 

 predaceous beetles, and the bobolink destroy many. Fair 

 results in a wheat field, infested by Army Worms, have been 

 obtained by dragging a long rope over the top of the 

 stalks, jarring the worms to the ground. This repeated 

 twice a day in small fields and where the worms are not too 

 thick would prove advantageous, but in larger fields it is a 

 question whether the results would equal the time and 

 labor expended.
