东北地区落叶松毛虫研究进展

落叶松毛虫是我国东北地区重要的森林害虫之一,取食松针,对针叶树的生长发育为害巨大,从而严重影响该地区的木材生产和林产品产量与质量的提高.暴发时甚至会使针叶林成片的死亡,破坏针叶林的结构组成和生态功能,造成巨大的经济和生态损失.多年来我国学者对东北地区落叶松毛虫进行了大量的调查研究,并取得了丰硕的成果.根据前人的研究成果,从落叶松毛虫的形态特征、生物学特性、发生与环境条件的关系及综合防治措施等方面阐述了我国东北地区落叶松毛虫的研究进展,为该地区落叶松毛虫的可持续控制和针叶林的科学经营提供理论依据.

Research Progress of Dendrolimus superansis in Northeast of China

Dendrolimus superansis a mostly common forest pest in Northeast of China, with coniferous for food, has great harm to the growth of conifers, and seriously affect timber production and improving the yield and quality of forest products in this region, even making coniferous forests died into pieces when it outbreaks, destroy composition and ecological functions of coniferous forests, causing enormous economic and ecological losses. In recent years, many investigations about Dendrolimus superansis have been conducted, and lots of achievements have been achieved. According to the results of previous research, this paper overviewed the progress of Dendrolimus superansis in Northeast from the respects of morphological characteristics, biological characters, the relationship between outbreak and environment, comprehensive prevention measures, and provided a theoretical basis for sustainable control of Dendrolimus superansis and scientific operations of coniferous forests in this region.
