Spermiogenesis in boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae)

International Journal of Insect Morphology and Embryology, 1975
Abstract Spermiogenesis of Anthonomus grandis Boheman, the cotton boll weevil, was studied by transmission electron microscopy. The basic morphologic features investigated and illustrated were: acrosome, nucleus, fibrous masses, microtubules, and mitochondrial derivatives.

Chemosterilant and insecticidal activity of mixed aflatoxins against Anthonomus grandis (Coleoptera)

Journal of Invertebrate Pathology, 1978
Abstract A mixture of the four major aflatoxins at 0.06 ppm in food supplied to adult boll weevils, Anthonomus grandis , was an effective chemosterilant.

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

Discrimination of infested cotton squares by females of Anthonomus grandis

Journal of Pest Science, 2017
The 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.

Observations on the Pupae of Anthonomus grandis grandis Boheman and A. grandis thurberiae Pierce (Coleoptera: Curculionidae)

Annals of the Entomological Society of America, 1968
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

Metabolism of busulfan in the boll weevil (Anthonomus grandis Boheman)

Pesticide Biochemistry and Physiology, 1971
Abstract 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.

Acephate toxicity, metabolism, and anticholinesterase activity in Heliothis virescens (F.) and Anthonomus grandis grandis (Boheman)

Pesticide Biochemistry and Physiology, 1984
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.

Taxonomy of the Subspecies of Anthonomus grandis (Coleoptera: Curculionidae)

Annals of the Entomological Society of America, 1966
In 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 ...

The ecological basis of boll weevil (Anthonomus grandis Boheman) management

Agriculture, Ecosystems & Environment, 1983
Abstract The boll weevil (Anthonomus grandis Boheman), generally considered to be native to Mexico or Central America, spread into the southern United States of America in the late 1800s and seriously threatened the cotton industry. As there were no effective alternatives, pest control specialists studied the insect's ecology and advocated cultural ...
