摘　　要：组建并分析了柏小爪螨实验种群生命表。在25℃恒温条件下,种群的内禀增长力rm为0.1274,周限增长率λ为1.1358/d,净增殖率Ro为12.8746代,平均世代周期T为20.0586 d,种群增长一倍需要的时间t为5.4407 d。The life table of Oligonychus perditus population was studied at the constant temperature 25℃ in laboratory, The results showed that the instrinsic increase rate （rm） was 0.1724, the finite increase rate （λ） was 1.1358/d, the mean generation cycle （T） was 20. 0586 days and the doubling time （t） was 5. 4407 days. In age distribution of constant population, the percentage of the immature period was 92. 2520 % and the mature period was 7. 7241%.
