红脂大小蠹天敌研究进展

Research Progress on Natural Enemies of Dendroctonus valens LeConte

红脂大小蠹是我国重要的林业外来入侵害虫,给我国林业生产和生态建设造成了严重损害。分析其天敌使用概况,可为红脂大小蠹乃至整个小蠹类害虫的生物防治提供参考。基于红脂大小蠹在我国发生危害的相关研究,对其天敌使用情况进行了梳理和汇总。概述了现阶段红脂大小蠹的危害和传播情况,详细统计了捕食性天敌和寄生性天敌种类,分析了我国历年来利用天敌进行生物防治取得的成果。可为进一步系统地研究红脂大小蠹天敌组成、优质天敌资源的筛选、天敌内部成员互作关系和生态对策等提供参考。

Dendroctonus valens LeConte is an important alien invasive forestry pest in China,having caused serious damage to forestry production and ecological construction.The analysis of the use of natural enemies could provide a reference for biological control of red turpentine beetles and even for all the bark beetles.Based on the research of RTB damage in China,the use of natural enemies is analyzed and summarized.The study summarized the damage and spread of RTB,recorded the predatory enemies and parasitic enemies in detail,and analyzed the current achievements of biological control by natural enemies in China.The study provided references for further systematic researches on the composition of natural enemies,selection of high-quality enemy resources,interaction relationship of internal members and ecological strategies.
