中文摘要：三线钩蛾Pseudalbara parvula (Leech)是胡桃科和壳斗科树木的食叶害虫，核桃树受害很普遍。该虫1年发生2代，以蛹越冬。越冬代和第1代成虫于4月下旬和7月下旬开始羽化。文章报道其分布、寄主、生物学特性和天敌情况及防治方法。
英文摘要：Pseudalbara parvula (Leech), a defoliatior in some species of Juglandaceae and Fagaceae, caused defoliation on Juglans regia Li. It had two generations a year and overwintered as pupa. The adults of the first and overwintering generation emerged in late July and late April respectively. The paper reported its distribution, host, bionomics, natural enemies, and control methods.
