金斑喙凤蝶雄虫触角感觉器的扫描电镜观察

Scanning Electron Microscopy Observations of Antennal Sensilla of the Male Teinopalpus aureus Mell

对金斑喙凤蝶 (Teinopalpus aureus Mell)雄虫触角进行扫描电镜观察发现 :其触角有 3种感觉器 ,即星形感器、毛形感器和鳞形感器。星形感器数量最多 ,几乎密布整个触角 ;鳞形感器数量以触角基部分布较多 ,同时也分布于鞭节各节 ;毛形感器 (A、 B型 )数量最少 ,稀疏分布于鞭节各节。

Antennal sensilla of the male Teinopalpus aureus Mell was observed with a scanning electron microscopy. The antennae of the male consists of two basal segments and 37~38 flagellar segments. The sensilla can be classified into three types by morphology.Three types of sensilla were found on the antennae include sensilla stellate,sensilla trichodea, and sensilla squamiformia. The sensilla stellate are distributed to the whole antennae. The sensilla trichodea which are subdivided into two subtypes(designated A and B) are rarely distributed to the each flagellar segment. The sensilla squamiformia are distributed to the scape and pedicel and the each flagellar segment.
