白蜡树卷叶绵蚜(Prociphilus fraxini Fabricius)是白蜡树(Fraxinus chinensis Roxb.)的重要害虫,白蜡树叶被害后卷曲皱缩,发生数量多时全株树叶大部受害,影响白蜡虫种虫的培育和白蜡生产。近年来,此虫为害区有蔓延扩展趋势。为了防治其为害,我们在1976年片断观察的基础上又在1979—1981年在四川峨眉县定点进行了系统的生物学观
Prociphilus fraxini Fabricius, an important pest of Fraxinus chinensis Roxb., Leaves curled and shrunken when the leaves of the ash tree were damaged. Most of the leaves of the plant suffered the most damage when they occurred, affecting the growth of white wax insect and white wax production . In recent years, the insect-affected areas have spread the expansion trend. In order to prevent and control its damage, we conducted a systematic biological view in 1979 and 1981 in Emei County, Sichuan Province, on the basis of fragment observations
