摘　　要：触角是昆虫重要的感觉器官,其感觉功能主要是通过其上的各类感器来实现的。本文以染翅蝎蛉Sinopanorpa tincta(Nav偄s)和中华蚊蝎蛉Bittacus sinensis Walker为代表,采用扫描电子显微镜观察了蝎蛉科Panorpidae和蚊蝎蛉科Bittacidae触角感器的类型及其超微结构,并简要讨论了各种感器的功能。结果显示:染翅蝎蛉触角上共发现7种感器,分别为短刺形感器、Bhm氏鬃毛、毛形感器、短毛形感器、锥形感器、刺形感器、和微毛形感器。中华蚊蝎蛉触角上也发现7种感器,分别为Bhm氏鬃毛、芽形感器、毛形感器、刺形感器、畸形毛感器、腔锥感器和钟形感器。蚊蝎蛉触角与蝎蛉的最大区别是着生有大量的腔锥感器,初步推测众多的腔锥感器可能与蚊蝎蛉对湿度的高度敏感有关。The ultramorphology of the antennal sensilla was investigated in the scorpionfly Sinopanorpa tincta （Navás） and the hangingfly Bittacus sinensis Walker using scanning electron microscopy.Seven types of sensilla were found on the antennae of S.tincta：short sensilla chaetica,Bhm＇s bristles,sensilla trichodea,short sensilla trichodea,sensilla basiconica,sensilla chaetica,and sensilla microtrichia.On the antennae of B.sinensis seven types of sensilla were observed：Bhm＇s bristles,bud-shaped sensilla,sensilla trichodea,sensilla chaetica,anomalous sensilla trichodea,sensilla coeloconica,and sensilla campaniformia.The antennae of B.sinensis differ from those of S.tincta mainly in having numerous sensilla coeloconica,which may be related to its high sensitivity to the environmental humidity in the hangingfly.The functions of the various antennal sensilla are briefly discussed.
