| 摘 要： | 通过林间定期查迹调查、人工饲养和林间定株解剖等方法，对皱鞘双条杉天牛自然种群数量动态规律的研究，组建了自然种群生命表，并采用排除控制指数法（EIPC）对其进行了关键因子和阶段的分析，结果表明：幼虫期是种群消长的关键阶段。为综合治理皱鞘双条杉天牛提供一定的科学依据。

| Abstract: | The average natural population life table of The magnitude of Semanotus sinoauster Gressitt has been made based on the investigation in the forest stand regularly with breeding and anatomy of Semanotus sinoauster Gressitt at appointed trees. The average natural population life table was made. The key factor and stage were analysed by Exclusion Index of Population Control, EIPC. The results showed that the larvae is key stage. And so provide scientific basis for the integrated control on Semanotus sinoauster Gressitt. |

| Keywords: | Semanotus sinoauster Gressitt natural population life table mortality factor |
