摘　　要：利用扫描电镜观察烟草甲Lasioderma serricorne(Fabricius)成虫触角感器的形态和分布。结果表明,烟草甲成虫触角由柄节、梗节和鞭节组成,其中鞭节由9个亚节组成;在触角上共观察到毛形感器、刺形感器、锥形感器Ⅰ、锥形感器Ⅱ、锥形感器Ⅲ、锥形感器Ⅳ、钟形感器、B hm氏鬃毛和球状感器9种感器类型,其中锥形感器Ⅳ、钟形感器、B hm氏鬃毛和球状感器为新发现的烟草甲触角感器。此外,还讨论感器结构与功能的关系。The appearance and distribution of sensilla on the antenna of Lasioderma serricorne（Fabricius）were observed with scanning electron microscope（SEM）.The results showed that the antenna of L.serricorne adults consisted of scape,pedicel and 9 sub-segment flagellum.Nine kinds of sensillum were found in the antenna,including sensillum trichodeum,sensillum chaeticum,sensillum basiconicum（Ⅰ,Ⅱ,Ⅲ,and Ⅳ）,sensillum scolopale,Bhm bristle,and sensillum orbiculate.Sensillum basiconicum Ⅳ,sensillum scolopale,sensilla Bohm bristle and sensillum orbiculate were first discovered in L. serricorne. In addition, the structure-function relationship of the sensillum was discussed.
