grown, hght greenish in color, its back marked with nine fine, reddish 

 lines, somewhat interrupted at each segment. It works within the 

 stalk, but makes three or four holes to the surface, here and there, 

 through which it pushes out excrement. 



The adult moth expands three quarters of an inch. Hibernation 



may take place as adult, as larva in the stalks, or as pupa in the ground. 



The means of control include rotation of crops, prompt destruction 



of the remnants of infested stalks, and fall plowing 



and cultivation.
