摘要: 印度谷螟是我国危害性较严重的仓储害虫之一,食性很广,几乎危害每一种植物性仓储物.印度谷螟雌虫性信息素主要成份顺9,反12-十四碳二烯醇醋酸酯(TDA)早已被鉴定,并利用TDA单一组份诱捕印度谷螟雄蛾也较为有效,但该虫的完整信息素系统尚不清楚.本研究采用单个雌蛾性信息素腺体抽提技术,利用毛细管气相色谱GC保留时间定性方法和气质联用GC-MS分析鉴定技术,从印度谷螟雌虫腺体提取物中鉴定了顺9,反12-十四碳二烯醇醋酸酯(A),顺9,反12-十四碳二烯醇(B),顺9,反12-十四碳二烯醛(C)和顺9-十四碳醋酸醋(D)4种主要信息素成份,其比例为A:B:C:D=100:22:12:9.风洞试验结果表明,以该4种主要成分按A:B:C:D=8:2:1:0.8比例配制成的诱芯,其引诱雄蛾的活性接近于雌蛾腺体提取物.

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.

Key words: Indian meal moth, Sex pheromone, (Z,E)-9,12-tetradecadienyl acetate, Behavioral response
