Improving Cry8Ka toxin activity towards the cotton boll weevil (Anthonomus grandis) [PDF]

BMC Biotechnology, 2011
Background The cotton boll weevil (Anthonomus grandis) is a serious insect-pest in the Americas, particularly in Brazil. The use of chemical or biological insect control is not effective against the cotton boll weevil because of its endophytic life style.

Influence of two acyclic homoterpenes (Tetranorterpenes) on the foraging behavior of anthonomus grandis Boh [PDF]

Journal of Chemical Ecology, 2016
Previous studies have shown that the boll weevil, Anthonomus grandis, is attracted to constitutive and conspecific herbivore-induced cotton volatiles, preferring the blend emitted by cotton at the reproductive over the vegetative stage.

A New qPCR Assay for the Rapid Diagnosis of Anthonomus grandis Subspecies. [PDF]

Insects, 2023
Rapid and accurate identification of Anthonomus grandis subspecies is crucial for effective management and eradication. Current diagnostic methods have limitations in terms of time to diagnosis (up to seven days) and can yield ambiguous results.

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

Transcriptomic survey of the midgut of Anthonomus grandis (Coleoptera: Curculionidae). [PDF]

J Insect Sci, 2014
Anthonomus grandis Boheman is a key pest in cotton crops in the New World. Its larval stage develops within the flower bud using it as food and as protection against its predators. This behavior limits the effectiveness of its control using conventional insecticide applications and biocontrol techniques.

From flower buds to bolls: how cotton reproductive structures shape boll weevil development, reproduction and survival. [PDF]

Pest Manag Sci
Female boll weevils feeding on flower buds promote reproduction regardless of their immature diet, whereas boll feeding increases lipid reserves and lifespan, revealing a nutrition‐driven trade‐off that sustains survival and reproduction in tropical boll weevil populations.
