Noctuidse 
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.
