Noctuids 



cotton-fields and in the growing corn that the greatest damage 

 is inflicted. There appears to be no way of applying remedies 

 in a wholesale manner to the crops so as to prevent the depreda- 

 tions of this insect. The only resort is for the grower to go 

 carefully over the fields, and where he detects the presence of the 

 insects in their early stages, to pick them off and destroy them. 

 In the case of corn the presence of the worm is shown by the 

 premature drying of the silk, and in the case of cotton by the 

 fallen flower-buds, which lie withering on the ground.
