| 摘 要： | 组建了室内自然温湿条件下暗黑齿爪鳃金龟的生命期望表和生殖力表。室温下测得该虫的内禀增长率（rm）为0．0106,周限增长率（λ）为1．0107,净增殖率（R_0）为2．2277。模拟了该虫世代种群存活率曲线为Weibull分布曲线I型:Sp（t）＝exP－（t／2．7082）~(4.6827],种群自然增长过程符合二次三项式,logy＝a＋bx＋cx~2。经验曲线方程：logy＝0．6689＋0．3264。－0．0243x~2。

| Abstract: | This paper deal with the life expectation table and reproduction capacity table of Holotrichia parallela Motschulsky at natural temperature, humidity in laboratary. The results show that rm to be 0.0106, λ to be 1.0107, R, to be 2.2277. It to generation population survival rate diagratn of curve is Weibull distribution "I": S_p(t) = exp - (t/2. 7082)~(4.6827); increase law of natural population accord with experience curve equation: log Y = - 0. 6689 + 0 .3264x - 0 .0243x2. |
