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.

Effects of insecticides and defoliants applied alone and in combination for control of overwintering boll weevil(Anthonomus grandis; Coleoptera: Curculionidae)—laboratory and field studies [PDF]
Pest Management Science, 2004 In laboratory, greenhouse and field tests, we determined the effects of combining full rates of the defoliants tribufos and thidiazuron and the herbicide thifensulfuron-methyl with half rates of the insecticides lambda-cyhalothrin or azinphos-methyl, and

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

Abstract The toxicity (72 hr) of acephate and methamidophos to fourth-instar larvae of the tobacco budworm, Heliothis virescens (F.), was nearly equivalent. In contrast, toxicity (72 hr) of methamidophos to adult boll weevils, Anthonomus grandis grandis (Boheman), was substantially greater than that of acephate.

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.

Metabolism of busulfan in the boll weevil (Anthonomus grandis Boheman)
Pesticide Biochemistry and Physiology, 1971Abstract One-day-old male boll weevils, Anthonomus grandis Boheman, that had been forcefed 3 H, and 14 C-labeled busulfan were held for 24 and 72 hr, respectively. The resulting metabolites from the feces and extracts of the weevils were analyzed by thin-layer chromatography, gas-liquid chromatography, and mass spectroscopy.

Taxonomy of the Subspecies of Anthonomus grandis (Coleoptera: Curculionidae)
Annals of the Entomological Society of America, 1966In the years since the thurberia weevil, Anthonomus grandis thurberiae Pierce, was described, attempts to separate it from the boll weevil, A. g. grandis Boheman, by using the characters noted by Pierce have met with indifferent success. In an intensive study of specimens clearly representative of the 2 named subspecies of grandis , 3 characters were ...

Proteolytic processing of the vitellogenin precursor in the boll weevil, Anthonomus grandis
Archives of Insect Biochemistry and Physiology, 1993AbstractThe soluble proteins of the eggs of the coleopteran insect Anthonomus grandis Boheman, the cotton boll weevil, consist almost entirely of two vitellin types with Mrs of 160,000 and 47,000. We sequenced their N‐terminal ends and one internal cyanogen bromide fragment of the large vitellin and compared these sequences with the deduced amino acid ...

Devido ao seu alto poder de destruição o bicudo-do-algodoeiro (Anthonomus grandis grandis (Coleoptera: Curculionidae)) é considerado uma das principais pragas na cotonicultura brasileira. O principal método de controle contra o bicudo é o uso de inseticidas convencionais.
