Adverse effects caused by synthetic pesticides have increased interest in plant-derived insecticidal compounds, particular essential oils, as a more compatible and ecofriendly alternative for pest control of economic importance. For this reason, the oil isolated from leaves shoots Drimys winteri (J.R. Forster & G. Forster)-also named canelo (CEO)-was investigated its chemical profile action against Acanthoscelides obtectus (Say)-one most important post-harvest pests dry beans world-and...
The objective of this study was to evaluate the repellent effect essential oil rue (Ruta chalepensis) against weevil Aegorhinus superciliosus, an important pest fruit crops in Chile.Rue obtained by steam distillation, and its components were identified GC-MS.Their on adult A. superciliosus insects evaluated using four-arm olfactometric bioassays.The extraction process had a yield 0.3% dry weight basis, chromatographic analysis showed presence nine compounds, which represented 89.3% total...
The weevil Aegorhinus superciliosus Guérin (Coleoptera: Curculionidae), which is endemic to Central-Southern Chile and Argentina, one of the major berry pests in most important pest La Araucanía Region (38°44′9″S, 72°35′25″W). Due poor effectiveness problems surrounding implementation traditional control methods using organophosphate carbamate insecticides, new strategies for controlling this are needed. In communication, we evaluated behavioral responses male female A. volatile compounds...
