Antennal Morphology and Sensilla Distribution of Scambus punctatus(Hymenoptera: Ichneunmonidae) with Scanning Electron Microscopy Observation
摘要
Abstract
[Objective] The objective of this study is to define the external morphological characteristics of antennae and sensilla of Scambus punctatus. [Method] Morphological characteristics of the antenna and type, morphology, amounts and distributions of antenna sensilla of S. punctatus were examined and photographed with scanning electron microscopy. The differences in sensilla between both sexes were also compared. [Result] The antenna of male and female adult S. punctatus was both fiagelliform, and composed of scape, pedicle and flagellum. The female adult flagellum had twenty-two segments and the male had twenty-five segments. Five types of antennal sensilla were identified in an antenna, trichodea, placodea, coeloconica, chaetica and Bohm bristles. Sensilla trichodea were most abundant. Sensilla trichodea ( Ⅰ, Ⅱ), sensilla placodea, sensilla coeloconica and sensilla chaetica were found verticulate in flagellum, while sensilla trichodea (Ⅲ) were found in middle and distal end of scapes and pedicles. Bohm bristles were found at the base of scapes and pedicles. There were nosexual differences in sensillum morphology and type. There were sexual differences in sensillum number and density. The male sensillum number and density was more than the female. [Conclusion] The antenna of male and female adult S. punctatus is both fiagelliform. Five types of antennal sensilla were found in an antenna. The length of the antenna differed very much, but the distributions of the sensillum were similar. There were sexual differences in the number of sensory organs and density between male and female adults.关键词
