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.

Isolation and characterization of polymorphic microsatellite loci in the boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae) [PDF]

Molecular Ecology Notes, 2004
The boll weevil (Anthonomus grandis Boheman) is a major insect pest of cotton in North America. Dispersal activity poses a threat to ongoing eradication efforts in the US, but little is known about the frequency of long-distance migration.

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

Efficacy and Degradation of Fipronil Applied to Cotton for Control of Anthonomus grandis grandis (Coleoptera: Curculionidae)

Journal of Economic Entomology, 1999
Fipronil was applied to cotton by ground sprayer at ultralow volume and conventional spray rates. Boll weevil mortality and residue analysis of fipronil and its metabolites at 0,1, 2, 3, and 6 d after application were used to evaluate treatments. An evaluation of the toxicity of fipronil and metabolites to boll weevils also was conducted.

Digestive Anatomy of the Adult Boll Weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae)

Annals of the Entomological Society of America, 1981
A study of boll weevil digestive anatomy revealed previously unknown aspects, e.g. particularly, a series of dentate plates at the pyloric valve region, and micropores over the intima of the rest of the hindgut. Topographic differences were found between the brush border of the anterior midgut and that of the posterior midgut, and a cluster of ...

Karyotypic analysis of the cotton boll weevil, Anthonomus grandis Boheman

Genetica, 2000
The diploid chromosome number of the cotton boll weevil, Anthonomus grandis Boheman, is 44. Both C- and N-banding techniques of mitotic cells demonstrated constitutive heterochromatin in the p arm of the eight largest chromosomes, the p arm of the X chromosome, and the centromeric region of autosomal groups A-D.
