摘 要 ：对燕山东部浅山区赤松毛虫世代内种群数量动态规律进行了调查,分析了各虫期死亡原因及死亡率的变异程度,并对影响种群世代内总死亡率高低的关键虫期和关键因子进行了分析,建立了赤松毛虫世代内种群数量动态模拟模型。对于进行世代内赤松毛虫种群数量动态预测,油松受害程度估测具有一定意义。

Abstract:In this paper,the population dynamics of Dendrolimus spectabilis was studied in east Yanshan mountainl reasons for death and mortality variability in each stage were analysed;the key-stage and key-factor which effect the mortality of generation were discovered.The models to simulate population dynamics within the generation were developed.
