| 摘 要： | 通过对马铃薯瓢虫自然种群的田间系统调查和室内实验种群的饲养观察,组建了以作用因子组配的马铃薯瓢虫自然种群生命表,结果表明：马铃薯瓢虫世代种群趋势指数（I）为37.28,世代总成活率为16%。控制指数大小比较结果表明,捕食和雨水冲刷是威胁种群生存的最重要阻碍因子。

| Abstract: | The natural population life table of Henosepilachna vigintioctomaculata（Mots.） based on factor groups was built with systematic survey of the field population and observation to laboratory one,The results showed that the index of population trend in generation（I） of H.vigintioctomaculata was 37.28,the total survival rate is 16% from generation to generation.Predation and rainfall were the most important factors impeding population survival. |
