宁夏朱砂叶螨实验种群生命表的组建与分析

ESTABLISHMRENT AND ANALYSIS ON LIFE TABLE FOR EXPERIMENTVL POPULATION OF TETRANYCHUS CINNABARINUS IN NINGXIA

本文通过在２５°恒温条件下，以１５Ｌ９Ｄ和９Ｌ１５Ｄ两种不同光周期下饲养朱砂叶螨，分别组建其生命表。并用Ｍｏｒｒｉｓ模式和庞雄飞的组分分析公式，探讨光周期对朱砂叶螨种群动态的关系；并组建了在两种光周期下的种群生殖力表，以计算ｒｍ，入、Ｒｏ、Ｔ等指标。

This paper deals with the life table of Tetranychus cinnabarinus at constant temperature of 25℃ with two photoperiods of 15L9D and 9L15D, analysed the relationship between photoperiod and population dynamics of the mite with Moms mathematical model and elements model, the index of r_m(intrinic rate of natural increase),λ(finite rate of increase),Ro(net productive rate)and r_m T were obtained from the reproductive capacity life table.at two photoperiods had been established.
