摘　　要：研究表明库尔勒香梨上发生的蚧壳虫优势种 ,并非习惯上称呼的梨圆蚧Quadraspidiotuspernicio sus (Comstock) ,而是橄榄片盾蚧Parlatoriaoleae (Colv e)。橄榄片盾蚧 1年发生 2代 ,以受精雌成虫在枝干上越冬 ,产卵繁殖后代 ,严重危害寄主枝条、果实及叶片。防治的关键时期是Parlatoria oleae (Colvee) is the major pest of the Kurle fragrant pear in Xinjiang, where it appears to be a local dominant species of Diaspididae. This pest heavily attacks the branches, leaves and fruits of its host. It has 2 generations per year and overwinters as impregnated female adults. The middle ten days of May in Kurle is the crucial period for controlling the pest.
