Improving Cry8Ka toxin activity towards the cotton boll weevil (
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.

Pest categorisation of Anthonomus grandis [PDF]
EFSA Journal, 2017 The European Commission requested EFSA to conduct a pest categorisation of Anthonomus grandis (Coleoptera: Curculionidae), an oligophagous pest weevil feeding on Malvaceae, including Gossypium spp., Hampea spp., Cienfuegosia spp.

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. Moreover, this preference was paralleled by the release of the acyclic homoterpenes (tetranorterpenes) (E)-4,8 ...

Nucleases as a barrier to gene silencing in the cotton boll weevil, Anthonomus grandis. [PDF]
PLoS ONE, 2017 RNA interference (RNAi) approaches have been applied as a biotechnological tool for controlling plant insect pests via selective gene down regulation. However, the inefficiency of RNAi mechanism in insects is associated with several barriers, including ...

Fertility Life Table, Thermal Requirements, and Ecological Zoning of Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae) in Brazil. [PDF]
Insects, 2023 The boll weevil, Anthonomus grandis grandis Boh., is the most important cotton pest in Central and South America. The biological characteristics and thermal requirements of boll weevils reared on an artificial diet were assessed at seven constant temperatures (18, 20, 22, 25, 28, 30, and 32 ± 1 °C) under laboratory conditions.

The Transcriptomic Response of the Boll Weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), following Exposure to the Organophosphate Insecticide Malathion. [PDF]
Insects, 2023 Insecticide tolerance and resistance have evolved countless times in insect systems. Molecular drivers of resistance include mutations in the insecticide target site and/or gene duplication, and increased gene expression of detoxification enzymes. The boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is a pest of commercial ...

Transcriptomic Survey of the Midgut of Anthonomus grandis (Coleoptera: Curculionidae) [PDF]
Journal of Insect Science, 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.
