摘　　要：华山松大小蠹、红脂大小蠹和云杉大小蠹是危害中国松属的重要大小蠹属害虫,给森林生态系统带来极大破坏。华山松大小蠹是先锋型害虫,可直接危害健康华山松。红脂大小蠹和云杉大小蠹为检疫性害虫,主要危害衰弱木,有些情况下也可侵染健康木。由于大小蠹危害隐蔽,一经发现便已造成林木死亡,给森防工作带来极大困难。通过概述三种大小蠹的生物学习性,分析了入侵机制、适生性和风险评估情况,并在此基础上对三种大小蠹的天敌昆虫进行了统计和预估分析,可为进一步开发和利用天敌昆虫提供参考依据。Dendroctonus armandi,D.valens and D.micans are special pests of P.armandii in China,take a great destruction to forest ecology.D.armandi is the pioneer pest of P.armandii,can be directly harm.D.valens and D.micans are quarantine pests,mainly harms weak trees,sometimes,can infect healthy woods.Because of the harm is hidden,it has caused death once found.The authors summarized the biological characteristics,adaptability and risk assessment of Dendroctonus,and based on the results,statistical and prediction analysized of the natural enemies of Dendroctonus,provided reference for further exploitation and utilization of natural enemy insects.
