日本龟蜡蚧发育过程中形态和蜡腺变异特征的研究

日本龟蜡蚧ＧｅｒｏｐｌａｓｔｅｓｊａｐｏｎｉｃｕｓＧｒｅｅｎ是我国多种园木树林的大害虫。它的形态和泌蜡腺体在一生发育中主变异很大，由此引起生理的功能和蜡质成分及蜡壳形状等方面的变化，对形态分类、害虫检疫和防治有很大影响。本文研究了日本龟蜡蚧各龄期的形态和泌蜡系统的变异，对其显微结构进行详细描述和绘图，分析了蜡腺的分布形式和分泌功能及对蜡壳形成的影响。

A STUDY ON THE CHANGES OF THE MORPHOLOGY AND WAX CLANDS OF JAPANESE WAS SCALE

The Japanese wax scale,Ceroplastes japonicus Green has four and five instars for the felame and male respectively.The almost same characteristics are showed for both sex of nymphs in their first and secondinstars.But the great different are appeared in the morphological and wax glands.after the first two instars.The female develops into its 3rd instar,then adult stage.Meanwhile,the male becomes into prepupa,then pupa,finaly adult.This study is focused on the morphological and wax gland chenges of the insect over its life cycle.Five figures are presented in the paper.
