白蜡树卷叶绵蚜Prociphinus fraxini F.是白蜡虫寄主植物——白蜡树的严重害虫之一。叶片受害后卷曲皱缩,数量多时全株树叶大部受害,影响白螨虫种虫培育和白蜡生产。近年来此虫发生区有蔓延扩展趋势。为了防止其危害,为我们在1976年于峨眉进行片断观察的基础上,1979——1981年对其生物学特性和防治方法进行了系统研究,现将结果整理如下。 Prociphinus fraxini F. is one of the major pests of the ash plant, a white waxy plant. Curly folds after the damage leaves, the majority of the whole plant leaves most affected victims of white mite insects and white wax production. In recent years, the occurrence of this worm has spread the expansion trend. In order to prevent its harm, based on the observation of the fragments of Emei in 1976, we systematically studied its biological characteristics and prevention methods from 1979 to 1981. The results are summarized as follows.
