中文摘要：

落叶松毛虫是我国东北林区的主要森林害虫之一，影响林木的生长发育和林产品质量提高，影响森林的结构组成和生态功能，严重爆发时甚至会改变森林的演替方向，造成巨大的经济和生态损失。多年来我国学者一直重视对落叶松毛虫的调查研究，并取得了丰硕的成果。本文从落叶松毛虫的发生与环境条件的关系、生物学特性、防治措施、预测预报以及国内的研究展望等几方面阐述我国大兴安岭地区落叶松毛虫的研究进展情况，为落叶松毛虫可持续控制和森林可持续经营提供理论支持。

英文摘要：

Dendrolimus superans is a mostly common forest pest in Northeastern China. It has severely impacts on the stand growth and the quality of forests. It also can alter the forest structure and function.
