Abstract: Indian meal moth Plodia interpunctella H黚ner (Lepidoptera:Pyralidae) is considered as an important insect pest infesting stored grains and other products in China.The major sex pheromone component of P.interpunctella,Z9,E12-14:OAc (TDA),has already been identified.Though the efficiency of male capture by using the bait with this component alone is quite good,the pheromone system is far from fully understood.The identification with capillary chromatographic analysis and GC-MS methods showed that there were four main components,i.e.,Z9,E12-14:OAc(A),Z9,E12-14:OH(B),Z9,E12-14:Ald(C),and Z9-14:OAc(D),in the sex pheromone gland of female P.interpunctella,and the ratio of these four components was A:B:C:D=100:22:12:9.Wind tunnel experimental results suggested that the response of male P.interpunctella to a blend (A:B:C:D=8:2:1:0.8) was not significantly different from that to female sex pheromone gland extracts.
