| 摘 要： | 在室内自然条件下,用山楂叶螨幼若螨为饲料饲养芬兰钝绥螨,组建了生殖力表,进而测定了其种群生物学参数;芬兰钝绥螨的种群内禀增长力γ_m=0.1299;净生殖率R_o=19.9645;周限增长率λ=1.1387;平均世代周期T=23.0396,该种群对干扰反应时间T=-7.6982ln(1-M)。

| Abstract: | This paper constructs the reproductive table of Euseius finlandicus reared with larvae and nymphae of Tetranychus viennensis under the natural condition of the laboratory.The major parameters of the population are gained as follows: the intrinsic increase capacity (γ_m)=0.1299/day, the net reproductive rate (R_0)=19.9645/generation, the finite rate (γ)=1.1387/day, the mean generation time(T)=23.0396 days. |
