刺桐姬小蜂成虫感器超微结构的研究

应用环境扫描电镜(ESEM)对刺桐姬小蜂Quadrastichus erythrinae Kim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7种感器,分别为毛形感器、刺形感器、多孔板状感器、剑状感器、耳状感器、乳状感器和带状感器;口器上则有2种感器,分别为刺形感器、锥形感器;在足上有3种感器,分别为毛形感器、刺形感器、锥形感器;在腹部末端也有4种感器,分别为毛形感器、刺形感器、锥形感器和腔形感器.并对雌虫和雄虫感器的差别进行了描述和讨论.

Ultrastructural Studies on Sensilla of Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae) Adult

The morphology and distribution of sensilla on antenna, compound eye, mouthparts, legs and terminal abdomen of Quadrastichus erythrinae Kim adult were observed by means of environment scanning electron microscope. It was found that seven types of sensilla, trichodea sensilla, chaeticum sensilla, multiporous plate sensilla, swordlike sensiUa, auriform sensilla, mammilliformia sensilla and zonated sensilla were on the surface of antennae;two types of chaeticum sensilla and basiconca sensilla were on the surface of mouthparts; three types of trichodea sensilla, chaeticum sensilla and basiconca sensilla were on legs;four types of trichodea sensilla, chaeticum sensilla, basiconca sensilla and coeloconica sensilla were on the terminal abdomen. The difference of the sensilla types and distribution between sexes were described and discussed.
