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.

A Classification Model of Cotton Boll-Weevil Population

Latin American Computing Conference / Conferencia Latinoamericana En Informatica, 2022
Integrated pest management (IPM) seeks to minimize the environmental impact of pesticide application. IPM is based on two important aspects —prevention and monitoring of diseases and insect pests— which today are being assisted by sensing and artificial ...

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 plants overexpressing the Bacillus thuringiensis Cry23Aa and Cry37Aa binary-like toxins exhibit high resistance to the cotton boll weevil (Anthonomus grandis).

Plant Science
The cotton boll weevil (CBW, Anthonomus grandis) stands as one of the most significant threats to cotton crops (Gossypium hirsutum). Despite substantial efforts, the development of a commercially viable transgenic cotton event for effective open-field ...

Dispersal of boll weevil toward and within the cotton plant and implications for insecticide exposure.

Pest Management Science, 2020
BACKGROUND Immature stages of boll weevil complete development endophytically leaving only the adult stage accessible for chemical control. We tested the hypothesis that boll weevil colonization of the cotton plants significantly affects their exposure ...

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 ...
