对栗绛蚧的形态、生活史及生活习性进行了较详细的描述。该虫在河南信阳 1a发生 1代 ,以 2龄若虫越冬 ,翌年 3月上旬树液流动后开始取食 ,4月中旬虫体迅速膨大 ,为危害盛期。作者根据该虫的生物学特性提出了防治对策 ,采取化学防治可取得良好的防治效果 A detailed description of the morphology, life history and living habits of the Liriomyces javanica is given. The insects occurred in Xinyang 1a of Henan for one generation, crossed with the second instar nymphs, and began to feed after the sap flow in early March. In the middle of April, the parasites rapidly swelled to jeopardize the peak. According to the biological characteristics of the insect put forward control strategies, chemical control can be achieved good control effect
