摘　　要：栎舞毒蛾Lymantria mathura Moore在我国东北天然次生林内周期性大发生,主要危害蒙古栎Quercus mongolica、黑桦Betula dahurica和枫桦B.costata。作者通过多年实地调查,观察了该虫的生物学特性,并对影响其种群动态的环境因子进行了系统分析,结果表明:冬春季的气温和降水量是影响其种群数量的关键因子,该虫对林木的危害程度取决于春季和初夏的气温和降水。Lymantria mathura Moore breaks out periodically in secondary natural forest in north eastern China, It mainly feeds many broad-leaved trees including Quercus mongolica, Butula dahurica and B. costata. Based on years of field investigations, the author systematically analyzed the factors influen- cing the population dynamics of L. mathura and concluded its development regulation. The results indi- cated that the temperature and rainfall in spring and winter were the critical factors influencing the pop- ulation fluctuations, while the temperature and rainfall in spring and early summer were the critical fac- tors influencing their damage degree on trees.
