Identification of pheromone synergists in american palm weevil, Rhynchophorus palmarum, and attraction of related dynamis borassi Inra
Rochat, D.; Nagnan-le Meillour, P.; Esteban-Duran, J.R.; Malosse, C.; Perthuis, B.; Morin, J.P.; Descoins, C..
Thirteen host-plant kairomone blends, including 28 compounds, were tested and showed moderate to high synergy with rhynchophorol. The blends plus rhynchophorol also attracted the related Dynamis borassi. Ethanol–ethyl acetate blends in various ratios showed moderate synergy. Two blends, including "characteristic coconut" odor molecules, were as efficient as sugarcane in synergizing rhynchophorol and field luring American Palm weevils (APWs). Preliminary olfactometer tests of natural host-plant volatiles demonstrated the role of fermentation in primary APW attraction. The synergists were chosen from a comparative study of the odors emitted by four plant materials attractive to the APW: sugarcane, coconut, Jacaratia digitata tree and Elaeis guineensis (Oil...
