摘　　要：【目的】观察比较黑斑双叉叶蝉Chlorotettix nigromaculatus成虫雌、雄两性的触角及其感器的形态、数量和分布,为黑斑双叉叶蝉的行为生物学、化学生态学和电生理学的研究提供参考。【方法】利用扫描电镜技术,观察黑斑双叉叶蝉成虫的触角外部形态及其感器的类型、数量和分布及超微结构。【结果】黑斑双叉叶蝉雌雄成虫触角感器类型、数量和分布相似。该虫成虫触角呈刚毛状,包括柄节、梗节和鞭节3部分,其中柄节和梗节较粗短,其上布满众多鳞形突起;鞭节细长,由约60～64亚节组成,鞭节第1亚节上也布满鳞形突起。成虫的触角感器分为7种类型,包括蒲氏鬃毛(Bhm bristles, BB)、毛形感器(sensilla trichodea, ST)、锥形感器(sensilla basiconica, SB)、钟形感器(sensilla campaniformia, SCa)、刺形感器(sensilla chaetica, SCh)、腔锥形感器(sensilla coelocomica, SCo)、分叉感器(forficate sensilla, FS)。其中蒲氏鬃毛主要分布在柄节和梗节中下部,毛形感器STⅠ和STⅡ分布在柄节、梗节和鞭节,锥形感器主要分布在鞭节第1和2亚节端部,钟形感器SCaⅠ和SCaⅡ分布在柄节和鞭节第3和5节端部,腔锥形感器SCoⅠ和SCoⅡ分布在鞭节第1-5亚节,刺形感器SChⅠ和SChⅡ分布在梗节中上部和鞭节第4亚节端部,分叉感器分布在梗节基部。触角感器类型和基本结构在雌雄个体间无明显差异。【结论】黑斑双叉叶蝉的触角感器类型、分布和数量在雌雄个体间无差异。各种感器分布具有一定的规律性。首次发现在其柄节和梗节分布有蒲氏鬃毛,梗节上有刺形感器和分叉感器,鞭节第1-5亚节上分布有腔锥形感器。【Aim】This study aims to compare antennae and the types,number,and distribution of the antennal sensilla between male and female adults of the leafhopper Chlorotettix nigromaculatus,so as to lay a basis for studying the behavior biology,chemical ecology and electrophysiology of this pest.【Methods】The antennal morphology and the types,number,distribution and ultrastructure of antennal sensilla in C.nigromaculatus adults were observed under scanning electron microscope.【Results】The types,number,and distribution of the antennal sensilla are similar between male and female adults of C.nigromaculatus.The adult antenna of this leafhopper is bristle-like,and consists of scape,pedicel and flagellum.The scape and pedicel are short and wide,with numerous squamiformia denticles.The long and slender flagellum consists of 60-64 flagellomeres,and there are numerous squamiformia denticles on the 1st flagellomere.There are seven sensilla types on antennae,including B hm bristles(BB),sensilla trichodea(ST),sensilla basiconica(SB),sensilla campaniformia(SCa),sensilla chaetica(SCh),sensilla coelocomica(SCo)and forficate sensilla(FS).Among them,the B hm bristles are distributed on the basal scape and the lower-middle pedical,the sensilla trichodeaⅠandⅡexist on the scape,pedical and the 3rd flagellomere,the sensilla basiconica are on the tips of the 1st and 2nd flagellomeres,the sensilla campaniformiaⅠandⅡon the basal scape and the tips of the 3rd and 5th flagellomeres,the sensilla coelocomicaⅠandⅡon the 1st-5th flagellomeres,the sensilla trichodeaⅠandⅡon the middle-upper pedicel and the tip of the 4th flagellomere,and the forficate sensillum on the basal pedicel.No differences were observed in the shapes and basic structures of the antennal sensilla between the male and female individuals.【Conclusion】The types,distribution and number of the antennal sensilla between male and female adults of C.nigromaculatus are not significantly different.The distribution of various sensilla shows certain patterns.It
