中红侧沟茧蜂触角超微结构
Antenna Ultrastructure of Microplitis mediator
摘要
Abstract
[Objective] The objective of this study is to investigate the types, distribution, morphology and internal structure of antennal sensilla of M. mediator. [Method] Scanning electron microscope (SEM) and transmission electron microscope (TEM) were used for the observation. [Result] The results of SEM show that antennae of M. mediator were made up of scape, pedicel and flagellum, which comprises 16 flagellomeres. Both the antennae of male and female contain six kinds of antennal sensilla, namely, sensillum trichodium, sensillum chaeticum, sensillum placodeum, sensillum basiconicum I, sensillum basiconicum II and sensillum coeloconicum. There was no significant difference in length, distribution and amount of each kind of sensillum between male and female M. mediator. The results of TEM show that there were porous thick cuticular wall and dendrites in lumen in sensillum trichodium and sensillum coeloconicum, aporous thick cuticular wall and dendrites in lumen in sensillum chaeticum and sensillum basiconicum I , porous thin cuticular wall and dendrites in lumen in sensillum placodeum and aporous thick cuticular wall and no dendrites in lumen in sensillum basiconicum II. [ Conclusion ] In this work, the internal and external ultrastructure of M. mediator antennal sensilla is obtained, and the results could provide a theoretical basis for olfactory perception behavior of parasitoids.关键词
