华山松大小蠹天敌昆虫的研究进展

Research advances of natural enemy of Dendroctonus armandi

华山松大小蠹(Dendroctonus armandi Tsai and Li)是中国特有种,是为害华山松的先锋型害虫,给秦巴山区森林生态造成了极大的破坏。由于其为害具有隐蔽性,发现时已造成华山松死亡。研究概述了现阶段华山松大小蠹的发生规律、入侵机制和风险评估情况,并基于此对华山松大小蠹及大小蠹属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 armandiis an endemic species and a pioneer pest of Pinus armandii in China,take a great destruction to Qinba mountainous forest ecology.Because of the harm is hidden,it has caused death once found.The occurrence regularity,instrusion mechanisms and risk assessment of P.armandii was summarized,and based on the results,the natural enemies of Dendroctonus armandi and Dendroctonus were analyzed statistically and forecastly,which could provide reference for further exploitation and utilization of natural enemy insects.
