| 摘 要： | 对华北地区经济树种蚧虫的种类区系、发生和分布规律及为害特点进行了系统研究。据调查，现已知华北经济树种蚧虫共有９科１２２种。随纬度增高、立地条件恶化、植物群落简单、人为活动频繁、管理水平粗放，蚧虫种类增多，为害严重。一般情况下，观赏树木受害普遍，温室植物受害严重，果树及平原地区林木部分受害，山地森林受害轻微。

| Abstract: | The species, fauna, occurrence and distribution of scale insects(Coccoidea) attact- ing economic trees in North China are studied. There are 122 species of scale insectbe-longing to 9 families,on the economic trees in North China.The scale insect species is more frequently and its damage to the host more seriously where the host isin higher latitude, in poorer site,in simpler plant community, with more frequent human activities and at more ex-tensive management level. In general,ornamental trees are damaged extensively, green-house plants are damaged seriously,fruit trees and forest trees in plain are damaged to lesser extent,and the forest trees in mountain are damaged only slightly. |
