摘　　要：组建了云南松毛虫越冬代自然种群平均生命表,并对其进行了关键阶段的分析,结果表明:种群消长趋势指数(I)大于1,种群呈上升趋势;成虫期的变动趋势与总K值相一致,说明成虫期是影响越冬代种群消长的关键阶段.The average life table of the natural population of the hibernating generation of Dendrolimus houi was constructed,and the key stage was analysed.The results showed that when the index of natural population fluctuation trend was more than one,the population was increasing.The fluctuant trend of imaginal period was the same as the one of total K value,namely,the imaginal period was the key stage which affected the population fluctuation trend of hibernating generation.
