The Cotton Boll Weevil (Anthonomus grandis Boh.) 
No pest of recent years has wrought greater damage than this in- 
vader from Mexico. It is now distributed throughout the greater 
part of the cotton-growing regions. 
Both the squares and the bolls are attacked, their substance eaten 
out, and their contents so damaged that they die or fail to produce 
fiber. The injury is wrought both by the adults in their feeding and 
egg-laying punctures, and by the grubs which hatch from the eggs 
laid within the bolls or squares. 
The adult boll weevil is a small snout beetle, one fourth of an inch 
long. It is brownish in color through most of its existence, but lighter 
when newly emerged and darker after it has been out for two or three 
weeks. The grub, found only within the squares or bolls, is whitish, 
heavy bodied, and has a dark head. It has no feet.
