Identification of Volatile Compounds Involved in Host Location by Anthonomus grandis (Coleoptera: Curculionidae) [PDF]

open access: yesFrontiers in Ecology and Evolution, 2018
Phytophagous insects rely on plant volatiles to locate suitable hosts upon which to feed or oviposit. The boll weevil, Anthonomus grandis, is the main pest on cotton crops in the Neotropical region and is attracted to host plant volatiles, especially ...

Influence of Two Acyclic Homoterpenes (Tetranorterpenes) on the Foraging Behavior of Anthonomus grandis Boh [PDF]

open access: yesJournal 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]

open access: yesPLoS 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 ...

Karyotypic analysis of the cotton boll weevil, Anthonomus grandis Boheman

open access: yesGenetica, 2000
The diploid chromosome number of the cotton boll weevil, Anthonomus grandis Boheman, is 44. Both C- and N-banding techniques of mitotic cells demonstrated constitutive heterochromatin in the p arm of the eight largest chromosomes, the p arm of the X chromosome, and the centromeric region of autosomal groups A-D.

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

open access: yesBMC 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.

Transcriptomic Survey of the Midgut of Anthonomus grandis (Coleoptera: Curculionidae) [PDF]

open access: yesJournal 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.

A New qPCR Assay for the Rapid Diagnosis of Anthonomus grandis Subspecies

open access: yesInsects, 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.
