Adult over-wintered females do not begin to deposit eggs 

 immediately upon entering a cotton field as it is necessary for 

 them to feed on squares about a week before eggs mature. 

 After this period of feeding, however, the over-wintered fe- 

 male is as prolific, if not more so, than a female that has not 

 lived through winter.

In w^ell drained pine woods surroundings such as are shown above, the 

 poisoning operation need not be continued after June 10 or 12. Weevils 

 emerge from such surroundings earlier in the spring than in damp mossy 

 situations, and are generally not as numerous. 



Very small amounts of poisoned-syrup mixture are required to mop an 

 acre of cotton with a poor stand such as shown here. This would not be the 

 case if the poison were applied w^ith a pow^er sprayer or dusting machine, 

 which would put most of the poison on the ground instead of the cotton plants.
