What is a boll weevil?

The boll weevil (Anthonomus grandis Boheman) is a cotton insect indigenous to Mexico that entered the United States into Texas in 1892. By the early 1920’s this insect had migrated through the cotton belt to Virginia, destroying the cotton crop. Since its arrival in the U.S. this insect has cost the cotton industry nearly $22 billion in damage and insecticide application costs.
