| 摘 要： | 本文报道冬虫夏草的三种寄主昆虫白马蝠蛾(Hepialus baimaensis)、 人支蝠蛾(H.Renzhiensis)和中支蚯蛾(H.Zhongzhiensis)触角感觉器种类、形态和分布的扫描电镜观察结果。三种蝠蛾触角表面均缺少网状覆盖物。计有七种感觉器，名称为毛形感器、刺形感器、锥形感器、腔锥感器、Bohm氏鬃毛、鳞形感器和钟形感器。毛形感器分A和B型，数量最多。鞭节上每节具有2-3只刺形感器和l-5只锥形感器。腔锥感器分为长栓和短栓两种形态类型，腔周围都无缘栓。 Bohm氏鬃毛主要分布于基节，数量较多。钟形感器仅在雄蛾触角上见到。各类感觉器在种间无明显差异。

| Abstract: | ntennal sensilla of the ghost moths Hepialus baimaensis, H. renzhiensis andH. zhongzhiensis. were observed with a scanning electron microscope. The antennaeof these three species each consists of two hasal segments and 21--27 flagellar segments. The sensilla can be classified into types according to their morphology. Sixtypes of sensilla found on the antennae of both sexes include sensilla trichodea, sensilla chaetica, sensilla basiconica, sensilla coeloconica, Bohm's bristles, and sensillasquamiformia. Moreover, sensilla campaniformia occur occasionally on male's only.The sensilla trichodea are further subdivided into two subtypes (designated A andB). Each flagellar segment possesses 2--3 sensilla sub-chaetica and 1--5 sensillabasiconica. There are two subtypes of sensilla coeloconica including center pegs oflong and short pattern, the sensilla lack inward slantwise fringe pegs mainly distributed on the flagellar segments. Bohm's tristles ate distributed to the scape and pedicel segment. The general pattern of numbers and distribution of these sensilla issimilar in all three species. The sensilla campaniformia have marked sexual dimorphism. |
