What is a boll weevil?
The boll weevil is the primary insect enemy of cotton. An adult is ¼ to ½ inch long, appearing tan to dark brown or gray in color, has a hard humpback-shaped shell and the characteristic snout accounting for about ¼ of its length. This pest has plagued U.S. cotton producers since 1892. It can complete an entire lifecycle in three weeks, lay 200 eggs per female–each in a separate cotton square or boll, ensuring the destruction of each–and spread rapidly, covering 40 to 160 miles per year.
