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.

Control of Boll Weevils in Cotton, 1991

Insecticide and Acaricide Tests, 1993
Abstract Insecticides were applied on 23, 27, 31, Aug and 6, 11 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 10.5 gal/acre at 60 psi through TX-6 hollowcone nozzles on a 19-inch spacing. Plots were 10,

Progress in Cotton Boll Weevil Control

Journal of Economic Entomology, 1926
The remarkable progress in control of the Mexican Cotton Boll Weevil, Anthonomus grandis , has been marked with, and is partly due to the thorough cooperation of all agencies concerned. The United States Department of Agriculture, Bureau of Entomology, and the state Experiment Stations have made their experimental results known with the aid of the ...

Control of Boll Weevil in Cotton, 1982

Insecticide and Acaricide Tests, 1983
Abstract A full-season study was conducted on the Plant Science Research Farm of the Mississippi Agricultural and Forestry Experiment Station, Mississippi State, MS, to determine the efficacy of various insecticides in controlling boll weevils in cotton. Plots were planted on May 22.

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 ...

Control of Boll Weevils on Cotton, 1980

Insecticide and Acaricide Tests, 1981
Abstract Treatments were applied on 8 x 65 ft plots, arranged in a randomized block design with 4 replications and 25 ft alleys. Nemacur 1.5 lb ai/acre was applied “in furrow” to control nematodes and thrips. Insecticide treatments were applied using a John Deere 6000 high clearance sprayer equipped with an auxiliary compressed air ...

Cotton pollen retention in boll weevils: A laboratory experiment

Palynology, 2009
Abstract Cotton pollen is thought to exist in the gut of boll weevils for at least 24 hours. Because finding whole or broken cotton pollen grains are valuable clues in determining when boll weevils were living in cotton, the retention of cotton pollen in the gut of the weevil was examined.
