| 中文摘要: |
| 组建并分析了辣椒上二斑叶螨实验种群生命表。在 23℃恒温条件下 ,种群的内禀增长力rm 为0.1510,周限增长率λ为1.1630/d ,净增殖率Ro为29.1497代 ,平均世代周期T为 22.3291d ,种群增长一倍需要的时间t为4.59d。在稳定种群年龄分布中 ,未成熟期占总量的88.9444% ,成熟期占11.0506%。 |
| 英文摘要: |
| The population life table of Tetranychus urticae Koch on chili plant was studied at the constant temperature 23℃ in laboratory. The results were as follow: The intrinsic increase rate (rm)=0.1510, the finite increase rate (λ)=1.1630/d, the net reproducitive rate (Ro)=29 149 7/ generation, the mean generation time (T)=22.3219 days and the doubling time (t)=4.59 days. In age distribution of constant population, the immature period was 88.944 4% and the mature period was 11.050 6%. |
