美国白蛾Hyphantriacunea (Drury)在秦皇岛市 1年发生 2～ 3代 ,其幼虫为害百余种植物的叶片 ,以蛹在枯枝落叶下、建筑物缝隙、树皮裂缝、土石块下等处越冬 ,具有食性杂、繁殖力强、适生范围广、传播速度快、危害严重等特点。通过 10a的防治试验 ,总结出了一套综合防治措施 ,如人工、生物及化学等防治方法 。
Hyphantria cunea has 2 or 3 generations a year in Qinhuangdao. Its larvae damage leaves of plants about 100 species. It overwinters in adult stage under dead branches and fallen leaves, crevices in the building, bark crevices et al.Its characteristics are high reproductive capacity,wide adaption,quickly propagating, seriously damaging et al.
