Five types of olfactory receptor neurons in the strawberry blossom weevil Anthonomus rubi: selective responses to inducible host-plant volatiles.
Plants release hundreds of volatiles that are important in the interaction with herbivorous animals, but which odorants are detected by which species? In this study, single receptor neurons on the antenna of the oligophagous strawberry blossom weevil Anthonomus rubi were screened for sensitivity to naturally produced plant compounds by the use of gas chromatography linked to electrophysiologica...
متن کاملImproving Cry8Ka toxin activity towards the cotton boll weevil (Anthonomus grandis)
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. Therefore, the use of biotechnological tools to produce insect-resistant transgenic plants represents an important strategy to reduce the dam...
متن کاملNucleases as a barrier to gene silencing in the cotton boll weevil, Anthonomus grandis
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 dsRNA delivery and uptake by the cell, dsRNA interaction with the cellular membrane receptor and dsRNA exposure to insect gut nucleases during f...
متن کاملGenetic Differentiation of Southeastern Boll Weevil and Thurberia Weevil Populations of Anthonomus grandis (Coleoptera: Curculionidae) Using Mitochondrial DNA
The southeastern boll weevil, the Mexican boll weevil, and the thurberia weevil are considered to be morphologically similar but behaviorally different variants of the same species, Anthonomus grandis Boheman. A polymerase chain reaction (PCR)-ampliÞed 9.2-kb section of the mitochondrial DNA was cleaved with restriction enzymes. RFLPs of weevils from three cotton growing locations in Texas and ...
متن کاملMolecular cloning of a cysteine proteinase cDNA from the cotton boll weevil Anthonomus grandis (Coleoptera: Curculionidae).
The cotton boll weevil (Anthonomus grandis) causes severe cotton crop losses in North and South America. This report describes the presence of cysteine proteinase activity in the cotton boll weevil. Cysteine proteinase inhibitors from different sources were assayed against total A. grandis proteinases but, unexpectedly, no inhibitor tested was particularly effective. In order to screen for acti...
