Assessment of synthetic chemicals for disruption of Rhynchophorus ferrugineus attraction

2012

The red palm weevil (RPW), Rhynchophorus ferrugineus, Olivier (Coleoptera: Curculionidae), is currently one of the most severe pests of Canary palms in urban areas of Mediterranean countries and Date palms in cultivated areas of the Middle East. RPW aggregation pheromone can be implemented for both monitoring and mass trapping, however risks of RPW "spillover" onto palms is of great concern. Aiming to discover repellent semiochemicals for safer RPW population management, we conducted electroantennographic (EAG) screenings of 17 commercially available synthetic compounds. These compounds represent three groups of plant volatiles (isoprenoids, phenyl propanoid derivatives and fatty acid deriv…
