Damaged bolls drop or develop abnormally after egg lay or feeding damage. Feeding signs may be recognized by a small hole in the square that turns dark with time. The cotton scout can recognize boll weevil feeding by the yellow to orange fecal material present on the square. Scouting Check for damaged squares during whole plant inspection at each sample site. Scouts should pay particular attention to areas next to overwintered sites where boll weevil damage occurs first.
