摘　　要：用分代隔离的方法,研究土耳其斯坦叶螨(Tetranychus turkestani Ugrov et Nikolski)6个世代的种群特定年龄生命表。通过对其种群生命表的IPC指数分析得出:捕食性天敌和气候因子是影响土耳其斯坦叶螨种群数量消长的主要因素。天敌捕食和气候因子作用可分别使土耳其斯坦叶螨种群趋势指数降低17.9862倍和2.2793倍。The age- specific life table of Strawberry Spider Mite of its natural population was studied in col-ton plant. Using some methods such as observation of two continuous generations etc, data of six generations were obtained. The analysis showed that the main factors causing the fluctuation of natural population were natural enemies and weather condition, the predaccous role of natural enemies and weather condition made the Index of population trend (Ⅰ) of Strawberry Spider Mite reduce 17. 9862 and 2. 2793 respectively.
