| 摘 要： | 组建并分析了苹果叶螨实验种群的特定年龄生命表和生殖力表。在23℃恒温条件下,种群趋势指数Ⅰ=6.4074/代,内禀增长力r_m=0.1296/d,周限增长率λ=1.1384/d,世代平均周期T=14.3547d。在稳定种群年龄分布中,未成熟期占总量的93.4789％,成熟期占6.5203％。

| Abstract: | This paper deals with the age-specific llfe table and fecundity table of Panonychus ulmi at the constant temperature of 23℃. The results were as follows. The innate increase capacity (γ_m)=0. 1296/d, the population tread index (I)=6. 4074/generation, the finite increase rate (λ)=1. 1384/d. the mean generation time (T)=14. 3547 d. In age distribution of constant population, the immature period was 93. 4789% and the mature period was 6. 5203％. |
