白斑新灰蝶触角感器的扫描电镜观察

An observation on antennal sensilla of Neolycaena tengstroemi by scanning electron microscopy

【目的】了解白斑新灰蝶触角感器的种类、数量及分布情况.【方法】利用扫描电镜对白斑新灰蝶雌、雄成虫的触角及触角感器进行观察研究.【结果】白斑新灰蝶星形感受器数量最多,有14 409个、毛形感受器次之,约为5 741个、刺形感受器、锥形感受器、耳形感受器数量居中,分别为256、125和560个.腔锥形感受器、腔形感受器、和鳞形感受器数量较少,分别为54、20和84个.【结论】白斑新灰蝶雌雄成虫触角上共8种感器,多集中于触角腹面.雌性感器数量多于雄性,感器类型和分布在雌雄间无明显差异.

【Objective】To understand the types,quantity and distribution of antennae sensilla on Neolycaena tengstroemi.【Method】Antennae and sensilla of male and female adults are observed with scanning electron-microscopy.【Result】N.tengstroemi has the most of sensilla stellate,the amount reaches 14409,then with 5 741 of sensillum trichodeum.The amount of sensillum chaeticum,sensillum basiconicum and sensilla auricillica are 256,125 and 560,respectively.Sensillum coeloconicum,sensillum cavity and sensilla squamiformia are 54,20 and 84.【Conclusion】The antennae of both male and female N.tengstroemi is found to contain eight kinds of antennal sensilla,which distribut in the ventral of the antennae.The females have more sensilla than that of male.There is no significant difference between male and female in type and distribution of the sensilla.
