THE BOLLWORM OR CORN EARWORM. 15 



INEFFECTIVE METHODS OF CONTROL. 



The burning of lights for the attraction of moths in fields is not 

 imconimon in certain sections and the idea of trapping the moths 

 by various devices is advocated often. Both of these methods have 

 been tested thoroughly and found of little or no value. In the first 

 place most of the moths caught are males, or females which have de- 

 posited their full quota of eggs, and in the second place a great many 

 beneficial insects which prey upon the bollworm in different stages 

 are destroyed. The placing of poisoned sweets in pans in the cotton 

 field also has been found to be a useless practice.
