| Abstract: | 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. |
