The boll weevil‐cotton plant complex

Toxicological & Environmental Chemistry Reviews, 1973
Abstract The boll weevil, Anthonomus grandis Boheman was introduced from Mexico into the United States about 1892. More than three‐fourths of all insect losses to cotton in this country have been attributed to this insect, and it is generally agreed that cotton cannot be profitably grown in areas where it occurs without adequate control measures.

Cotton Boll Growth in Relation to Boll Weevil Injury

Journal of Economic Entomology, 1926
This paper gives evidence that as the cotton bolls grow older they are less suceptible to boll weevil, Anthonomus grandis , injury, and the immunity at given ages varies with the variety. Dixie Triumph, Webber 49 and Humco Cleveland were the varieties studied, the first mentioned is the most susceptible and the last the most resistant.

The Boll Weevil Versus “King Cotton”

The Journal of Economic History, 1985
The boll weevil's impact on southern agriculture poses a dilemma. Micro-level evidence suggests the weevil triggered a transition out of cotton, but macro-level indicators fail to register much long-term impact. Econometric simulation of boll weevil impact—taking into account the low demand elasticity for southern cotton, differences between states in ...
