摘　　要：[目的]明确香蕉假茎象甲雌雄成虫触角感受器的超微结构、类型和分布。[方法]利用环境扫描电镜观察香蕉假茎象甲触角感受器的外部形态、类型及分布情况。[结果]该虫触角上感器类型多样,数量众多,雌雄成虫触角上均有5类12种感受器,包括6种毛形感受器、3种刺形感受器、1种锥形感受器、1种芽孢感受器和1种瓶形感受器。该虫触角上感器分布集中,以鞭节中上部最多,柄节腹面次之,梗节最少。[结论]触角感受器的类型在雌雄个体之间无明显差异,感受器的分布却存在性二型现象。[ Objective ] Ultra-structure, types and distribution of antenna sensillas of male and female Odoiporus longicollis were observed. [ Method ] The external form, types and distribution of antennae sensillas of O. longicoUis were observed by using environmental scanning electron microscope. [ Result ] The results showed that there were 5 types 12 kinds of sensillas on the antennae of both males and females,including 6 kinds of sensilla trichodeas,3 kinds of sensilla chaeticas, 1 kind of sensilla basiconcas, sensilla gemmiformium and sensilla doleiform. The order of sensilla distribution on antenna was upper part of flagellum 〉 segmental renter of scape 〉 pedicellus. [ Conclusion ] There is no obvious difference of antenna sensilla among males and females.
