Spatio‐temporal distribution of Anthonomus grandis grandis Boh. in tropical cotton fields
Pest Management Science, 2022AbstractBACKGROUNDKnowledge 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, 1959Part 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, 1968Abstract 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, 1971Abstract 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

Toxic sugars and longevity of Anthonomus grandis
Journal of Insect Physiology, 1972Abstract Toxic sugars ( d -arabinose, l -rhamnose, and l -sorbose) were fed to adults of the boll weevil, Anthonomus grandis. Based on longevity as a criterion, arabinose was the most toxic of the three sugars. When fed to newly emerged adults, sucrose protected against arabinose poisoning.

Discrimination of infested cotton squares by females of Anthonomus grandis
Journal of Pest Science, 2017The avoidance of infested squares of Gossypium hirsutum as oviposition substrate by females of Anthonomus grandis was studied following two approaches. First, the preference for oviposition in infested versus non-infested squares was studied in laboratory. Second, the distribution of ovipositions by A.

Typical pupae of the boll weevil, Anthonomus grandis grandis Boheman, from the southeastern United States were found to differ in certain respects from typical pupae of the thurberia weevil, A. grandis thurberiae Pierce, from Arizona. The differences are found in the relative length of a pair of tubercles on the rostrum, in the number of well-developed
