为全面了 解杏树林 害虫的 为害与 发生 规 律， 给 防 治提 供依 据， 采用 标 准地 方法 对 不同类型的 杏扁林进 行了系 统调查。 结果表明 ， 杏树林 害虫群 落共有６ 目２５ 科５５ 种， 优势 种集中于蚧虫 、蚜虫、卷 叶蛾等 类群及天 幕毛虫、 舞毒 蛾等 。树 木 年龄 可 影响 害 虫 群落 的 组 成、优势种数 量及危害 程度 。管 理水 平 对 害虫 发 生 有明 显 影响 ， 一 般 管理 水 平高 者， 害 虫 种类 少、危害较轻 。杏树林 害虫的 年发生规 律 是发 生周 期 短、优 势 种高 峰期 出 现早 、为 害期 集 中、群落凋落 迅速。 In order to fully understand the damage and occurrence rules of apricot groves and pests, the basis for prevention and treatment was provided, and different types of almond trees were systematically investigated by standard method. The results showed that Apricot grove community consisted of 6 orders, 25 families and 55 species. The dominant species were concentrated in scale insects such as scale insects, aphids, leaf roller moths and celestial caterpillars and gypsy moths. Tree age can affect the composition of pest communities, the number of dominant species and the degree of harm. Management level has a significant impact on the occurrence of pests, the general management level, fewer pests, less harmful. Apricot grove annual occurrence law is the occurrence of short cycle, the dominant species appear early peak, the concentration of harmful period, rapid community litter.
