Control of Boll Weevils in Cotton, 1990
Insecticide and Acaricide Tests, 1993Abstract Insecticides were applied on 24, 30, Aug and 3, 7, 12 Sep on ‘DPL 90’ cotton in Lonoke County, AR using a John Deere Hi-Cycle 6000 sprayer equipped with a CO2 powered system for spraying small plots. The sprayer was calibrated to deliver 10 gal/acre at 50 psi through TX-8 hollowcone nozzles on a 19-inch spacing. Plots were 9, 38-

The boll weevil‐cotton plant complex
Toxicological & Environmental Chemistry Reviews, 1973Abstract 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, 1926This 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, 1985The 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 ...
