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, 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 ...

The ecological basis of boll weevil (Anthonomus grandis Boheman) management
Agriculture, Ecosystems & Environment, 1983Abstract 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 ...

Abstract The neogregarine, Mattesia grandis McLaughlin, infects larvae and adults of the boll weevil, Anthonomus grandis Boheman, when the spores are ingested; larvae, pupae, and adults are susceptible. Sporogony and production of free spores usually occurred 7 days after infection. Development of the pathogen was retarded in adults when little or no
