Boll Weevil, Anthonomus grandisHost: Cotton.
Habitat: Adult weevils feed on and lay eggs in developing cotton bolls. Feeding punctures appear as small uncapped holes, while egg-laying punctures are covered with a small wart-like growth. Both types of punctures will cause squares and small bolls to drop. The white, legless larva feeds and pupates within the square or boll.
Life Cycle: Adult weevils spend the winter in ground trash near old cotton fields. Each female can lay up to 200 eggs (laying each egg in a separate cotton square or boll). The entire life cycle of egg to adult can be completed in 3 weeks or less. There are multiple (5 or more) generations per year.
Description: The adult weevils have a snout and are about one-fourth inch long. They vary from reddish-brown to gray to almost black in color. A distinguishing feature is the presence of two spurs on the front femur of each leg.
Control: Please contact your local county extension office for current information.
