摘要
在23±0.5℃条件下,用苹果树叶饲养李始叶螨Eotetranychus pruni (Oudemans)组建和分析了该螨实验种群生命表和生殖力表,得到有关种群特性的一些重要指标:——种群趋势指数,内禀增长力,周限增长率,净生殖率,世代平均周期等。
This paper constructs and analyses the experimental population life-table and reproductive table of Eotetranychus pruni(Oudemans) reared on the apple leaves at 23±0.5℃. Main population parameters of this species are gained as follows: intrinsic rate of increase, 0.1570; net reproductive rate, 14.6097; mean generation time, 17.0843 days; doubling time, 4.4150 days; finite rate, 1.1700; trend index of population, 15.1785.
