Spatio‐temporal distribution of Anthonomus grandis grandis Boh. in tropical cotton fields

Pest Management Science, 2022
AbstractBACKGROUNDKnowledge of the spatio‐temporal distribution of pests is important for the development of accurate management approaches. The boll weevil, Anthonomus grandis grandis Boh., is a deleterious cotton, Gossypium hirsutum L., pest in the western hemisphere. The spread of boll weevils across cotton fields remains poorly understood.

Diapause in Anthonomus grandis Boh.

Journal of Economic Entomology, 1959
Part of the boll weevil, Anthonomus grandis Boh., population enters diapause during late summer and early fall in Louisiana. Winter is passed in this condition. Diapause in this insect is characterized by cessation of gametogenesis and atrophy of gonads, increase in fat content, decrease in water content, and decrease in respiratory rate.

Physicochemical characteristics of glycogen from Anthonomus grandis Boheman

Comparative Biochemistry and Physiology, 1968
Abstract Glycogen was extracted from the boll weevil, Anthonomus grandis Boheman, with 5% trichloroacetic acid (TCA) and with cold chlorofomr-glycine buffer (cold water extraction). Glucose was the only sugar detected in acid hydrolyzates.

Absorption and metabolism of galactose and galactitol in Anthonomus grandis

Journal of Insect Physiology, 1971
Abstract Galactitol is a significant metabolite of galactose in fasted adults of Anthonomus grandis ; this is the first time that galactitol has been found to be a metabolite of galactose in an insect in vivo . Galactitol is not metabolized, and galactose, at best, is poorly metabolized by the boll weevil to trehalose and glycogen. Because sizeable
