| 摘 要： | 根据田间系统调查材料,分析了狼蛛等5种捕食天敌种群在早稻田的数量变动,并用逻辑斯谛方程模拟其变化过程.结果指出:狼蛛等5种捕食天敌总密度的数量变动,符合逻辑斯谛增长曲线,即水稻插植初期,这些天敌数量较少,随着禾苗生长,稻田天敌数量逐渐增多,到水稻生长中后期,其种群密度在一个平均密度的上、下波动.

| Abstract: | An investigation of five species predatory population dynamics in early rice field was conducted from 1983 to 1984.In the early stage of rice growing, the density of predators (Pardosa pseudoannulata, Verania discolor, Paederus fuscipes, Clubiona japonicola, Ophionea sp.) is low, but high in the middle and latter stages.A logistic simulation on this trend was made and the results fit the observed values. |
