摘　　要：组建了垫囊绿绵蜡蚧ChloropuicinariapsidiiMask.实验种群生命表.分析结果表明:垫囊绿绵蜡蚧实验种群的内禀增长率(rm)为0.196,相应的周限增长率(λ)为1.22,世代平均历期(T)为20.84d,净增长率(R0)为59.51.垫囊绿绵蜡蚧实验种群趋势指数(I)为59.98,在排除外界作用因子的条件下,该虫下代种群数量将为当代的59.98倍.The life table of experimental population of Chloropuicinaria psidii Mask. was constructed. The analysis results showed that the intrinsic rate increase (r_m) was 0.196, and the finite rate of increase (λ) was 1.22, while mean period of a generation (T) was 20.84 days, and net reproductive rate (R_0) was 59.51. The index of experimental population trend (I) was 59.98. It was expressed that the next population of C. psidii would increase 59.98 times without any interference in the environment.
