荔枝粗胫翠尺蛾触角感器的扫描电镜观察

利用扫描电镜对荔枝粗胫翠尺蛾雌雄虫触角上的感器进行观察和研究。结果表明,荔枝粗胫翠尺蛾雌虫触角丝状,雄虫触角羽状,分布有锥形感器、腔锥形感器、刺形感器、毛形感器、芽孢形感器、耳形感器、指形感器等7种感器,其中毛形感器数量最多,芽孢形感器雄虫特有。 The ultra-structure of the sensilla on the antenna of adult Thalassodes immissaria Walker was observed with a scanning electron microscope. The results indicated that the antenna of female moth was filliform and that of male moth was plumose. Seven types of sensilla were found, sensilla basiconica, sensilla coeloconica, sensilla chaetica, sensilla triehodea, sensiila sporangium, sensiIla auricillica and sensilla finger. A large proportion of sensilla was trichodea. Sensilla sporangium was male specific.
