Contains a review of the work done on this insect and a statement of the methods of 

 control recommended and the changes made in these recommendations as the investiga- 

 tions proceeded. Attention is called to the fact that spraying has been generally aban- 

 doned as a remedy and that hand picking is meeting with little favor.

 the futile use of Paris green as a remedy is presented. Emphasis is given to the necessity 

 of fall destruction of the cotton stalks in order to combat the pest.
