Cotton Weevil
The boll weevil (''Anthonomus grandis'') is a species of beetle in the family Curculionidae. The boll weevil feeds on cotton buds and flowers. Thought to be native to Central Mexico, it migrated into the United States from Mexico in the late 19th century and had infested all U.S. cotton-growing areas by the 1920s, devastating the industry and the people working in the American South. During the late 20th century, it became a serious pest in South America as well. Since 1978, the Boll Weevil Eradication Program in the U.S. allowed full-scale cultivation to resume in many regions. Description The adult insect has a long snout, a grayish color, and is usually less than in length. Life cycle 1) Dorsal view of adult; 2) side view of adult; 3) egg; 4) side view of larva; 5) ventral view of pupa; 6) adult, with wings spread Adult weevils overwinter in well-drained areas in or near cotton fields, and farms after diapause.

While most of the world's cotton producing nations are members, two of the ten largest producers (The People's Republic of China and Turkmenistan) are not members of the ICAC. All of the top five cotton exporting nations are members. The International Cotton Advisory Committee (ICAC) along with private sector cotton organizations initiated the International Forum for Cotton Promotion (IFCP) in 2000.
