桉树枝瘿姬小蜂成虫感器超微结构

应用扫描电镜对桉树枝瘿姬小蜂Leptocybe invasa Fisher & LaSalle成虫触角、复眼、口器、足以及腹部末端感器的超微结构和分布进行观察。结果表明,在触角上共有8种感器,分别为Bhm氏鬃毛Ⅰ、Bhm氏鬃毛Ⅱ、刺形感器、毛形感器Ⅰ、毛形感器Ⅱ、板形感器Ⅰ、板形感器Ⅱ和钟形感器;口器上有2种感器,分别为毛形感器Ⅳ和刺形感器;在足上有4种感器,分别为毛形感器Ⅰ、毛形感器Ⅲ、刺形感器和锥形感器;在腹部末端也有3种感器,分别为毛形感器Ⅰ、刺形感器和腔形感器。同时还探讨了触角上各种感器的功能。

Ultrastructure of sensilla of Leptocybe invasa

The morphology and distribution of sensilla on the antenna,compound eye,mouthparts,legs and terminal abdomen of Leptocybe invasa Fisher LaSalle were observed by means of a scanning electron microscope. Eight types of sensilla,namely Bhm bristles Ⅰ,Bhm bristles Ⅱ,chaeticum sensilla,trichodea sensilla Ⅰ,trichodea sensilla Ⅱ,placoid sensilla Ⅰ,placoid sensilla Ⅱ and campaniform sensilla,were found on the surface of antenna. Two types of sensilla,namely trichodea sensilla Ⅳ and chaeticum sensilla,were found on the surface of mouthparts. Four types of sensilla,namely trichodea sensilla Ⅰ,trichodea sensilla Ⅲ, chaeticum sensilla and basiconca sensilla were found on legs. Three types of sensilla,namely trichodea sensilla Ⅰ,chaeticum sensilla and coeloconica sensilla were found on the terminal abdomen. The biological function of the various kinds of sensilla found on the antenna is discussed.
