两种蝇蛹寄生蜂外生殖器及其感器的扫描电镜观察

Observation on Genitalia and Their Sense Organs of Spalangia endius and Nasonia vitripennis by Scanning Electron Microscopy (Hymenoptea:Pteromalidae)

本文首次对蝇蛹俑小蜂雌、雄性外生殖器进行了扫描电镜观察。同时与丽蝇蛹集金小蜂外生殖器进行了比较研究。首次报道了两种小蜂的外生殖器感器。在蝇蛹小蜂产卵针上发现有数个类似钟形感器的结构。产卵器鞘上着生有毛形及刺形感器。两种小蜂之雌雄性腹部第九背板上均有一对感觉窝,窝内着生有大量的长短不一的感觉毛。

In this paper,the male and female genitalia and their sense receptors of Spa- langia endius were observed by SEM.The structure of genitalia of Nasonia vitripennis was also discussed.It is found that the ends of the ovipositors of the two wasps are like sawtooth.There are several structures like campani- form sensilla in the ovipositor of S.endius.Both of the male and female of the two wasps have sense pits on the 9th tergum with a number of sense hairs of various length.
