中红侧沟茧蜂触角感受器的扫描电镜观察

利用扫描电镜对中红侧沟茧蜂Microplitis mediator的触角感受器进行了观察，发现了6个类型的感器，分别为毛形感器、板形感器、刺形感器、钟形感器、锥形感器、腔锥形感器。其中，毛形感器具有2种形态，锥形感器具有4种形态。钟形感器仅分布于雌蜂的触角上，锥形感器Ⅲ和Ⅳ仅分布于雄蜂的触角上。结合感受器的形态、分布和已报道的触角电位反应数据，对各感受器的功能进行了推测。

Antennal sensilla of Microplitis mediator observed with scanning electron microscope

The antennal sensory sensilla of the parasitoid, Microplitis mediator (Haliday) (Hymenoptera: Braconidae) were observed with scanning electron microscopy. Six distinct types of sense receptors were observed, including sensilla trichodea, sensilla placodea, sensilla basiconica, sensilla chaetica, sensilla coeleoconica, and sensilla campaniformia. Two forms of sensilla trichodea and four forms of sensilla basiconica were found. Sensilla campaniformia were only found on female antennae, while sensilla basiconicaⅢ and Ⅳ only on male antennae. Their functions were discussed in reference to their morphology, distribution, and the electroantennogram responses of the parasitoid previously reported.
