南美斑潜蝇触角感器的扫描电镜观察

摘要

利用扫描电镜对南美斑潜蝇触角形态和感器进行了观察.结果表明,南美斑潜蝇触角为具芒状,由柄节、梗节、鞭节三部分组成,鞭节上着生触角芒.触角感器有五种,分别为刺形感器、毛形感器、锥形感器、钟形感器和腔锥形感器,所有的触角感器都分布在鞭节上.雌雄成虫在触角形态、感器种类与分布上没有显著性差异.%The morphological characters of antenna and sensillum of the male and female of Liriomyza huidobrensis (Blanchard) were observed with a scanning electron microscope (SEM).The results showed that the aristate antenna consisted of the scape,pedicel and flagellum.There was an arista on the flagellum.Both female and male antennae of the species had the same 5 types of sensilla.They were identified as chaetic sensillum,trichoid sensillum,basiconic sensillum,campaniform sensillum and coeloconic sensillum.All of the sensilla were on the flagellum.No difference was found in the morphological characters of antennae and the type and distribution of the sensilla between the male and female adults.
