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.

The Arizona Cotton Boll Weevil Problem

Journal of Economic Entomology, 1926
The Arizona boll weevil is a variety of the well known boll weevil of the South. It is, however, specially adapted physiologically to thrive in arid regions. The natural host plant of the Arizona boll weevil is Thurberia or wild cotton. It has invaded cultivated cotton, however, and is now a serious menace.

Thermotropism of the Mexican Cotton Boll Weevil

Journal of Economic Entomology, 1929
A new apparatus for determining the thermotropic reaction of insects is described. The Mexican Cotton Boll Weevil (Anthonomus grandis Boh.) showed definite orientation in response to 26°F. at the chilled and 130°F. at the heated end of the apparatus, respectively.

Cotton, Cotton Bollworm, Tobacco Budworm and Cotton Boll Weevil Control, 1986

Insecticide and Acaricide Tests, 1987
Abstract Cotton was planted 16 May at the University of Georgia Experiment Station at Midville, GA, in Dothan loamy sand soil. The experiment was a randomized complete block design with 6 row plots × 100 ft long × 38 inch row width × 15 ft alleys with 4 replicates. Plants were treated with a high cycle sprayer using 3 hollow cone nozzles

Cotton Bollworm, Tobacco Budworm and Cotton Boll Weevil Control, 1976

Insecticide and Acaricide Tests, 1977
Abstract Lockett 4789-A was planted on May 24'76 at the South Central Research Station, Chickasha, Oklahoma at 20 lb per acre. Eight-row plots, 200 ft long, replicated in a complete randomized block design were used. Spray applications were made with a John Deere Hi-Cycle 600 sprayer traveling at a speed of 4.5 mph at 40 psi. Insecticide
