摘要： The plant bug, Adelphocoris fasciaticollis, has begun to resurge and become a key pest for cotton and alfalfa in northern China, along with the widespread cultivation of Bt cotton. To control this plant bug without pesticides, we attempted to develop a new approach by utilizing sex pheromone. The sex pheromone components from the whole-body extracts were analysed by GC-MS and gas chromatography-electroantennogram detector analysis (GC-EAD). (E)-4-Oxo-2-hexenal and hexyl butyrate, identified as the major components in the extracts of female bugs, elicited strong EAD responses. Field tests indicated that either (E)-4-oxo-2-hexenal or hexyl butyrate attracted few A.fasciaticollis males and was significantly less active than virgin females and the binary blend. Their ratio was optimized to be 1:11. Our results could expand acknowledge of the pheromone of mirids and provide novel approaches to monitor and control this plant bug without pesticides.
