摘　　要：【目的】双条杉天牛(Senmanotusbifasciatus)是柏属(Cupressusspp.)类植物的重要钻蛀性害虫,其成虫触角和口器结构与其搜寻和取食寄主植物的特性密切相关。弄清口器和触角感受器类型及其分布位置,探究双条杉天牛成虫与寄主植物互作机理。【方法】利用扫描电子显微镜观测双条杉天牛成虫口器、触角及其感受器的类型、分布位置。【结果】双条杉天牛口器上分布感受器有6种,即刺形感受器、锥形感受器、芽孢感受器、板形感受器、栓锥形感受器和鳞形感受器。触角上分布感受器有6种,即刺形感受器、钟形感受器、Bobhm鬃毛、毛形感受器、锥形感受器和栓锥形感受器。雌雄成虫的口器、触角及其感受器类型和分布位置均无显著差异。【结论】明确口器和触角感受器的类型及其分布位置,且在雌雄成虫间无明显差异,为探索快速高效搜索双条杉天牛成虫定位寄主植物的机理提供基础数据。[Objective]As an important borer pest of Cupressus spp.,antennae and mouthparts of Senmanotus bifasciatus are closely related to its harmful characteristics.Understanding the types and distribution positions of mouthparts and antennal sensilla would provide scientific basis for the study of the interaction mechanism between S.bifasciatus adults and host plants.[Method]The types and distribution of mouthparts,antennae and their sensilla of S.bifasciatus adults were observed by the scanning electron microscope.[Result]There were six types of sensilla identified from mouthparts of adults,including sensilla chaetica(sc),sensilla basiconca(sb),sensilla gemmiformium(sg),sensilla plate(sp),sensilla styloconica(ss),and sensillum squamiformium(sq).Also,there were six types of sensilla on the antennae,including sensilla chaetica(sc),campaniform sensillum(cs),Bobhm’s mane(Bob),sensilla trichodea(st),sb:sensilla basiconca(sb),and sensilla styloconica(ss).There was no difference in the sensilla between males and females on both mouthparts and antennae.[Conclusion]The study clarified the types and distribution positions of mouthparts and antennal sensilla,and there was no significant difference between male and female,providing basic data for exploring the mechanism of seeking and locating host plants in S.bifasciatus adults.
