摘要
在23±O.5℃温度条件下,室内饲养山楂叶螨Tetranychus viennensis(Zacher),组建其生殖力表,以测定该种群生物学参数,其结果如下:种群内禀增长力r_m为O.1240,净生殖率Ro为20.8156,平均世代周期T为24.4865。该种群的干扰反应时间可用公式:T=-8.06451n(1-M)计算(M表示种群受干扰后的死亡率)。
The fecundity table of Tetranychus viennensis was established at 23±0.5℃. The major parameters of the population were. the intrinsic increase capacity (r_m)=0.1240, the net reproductive rate(R_o) =20.8156/generation,the mean generation time(T)=24.4865 days. Survival rate curve given in this paper resembles Deevey Type III in shape. In addition, the theoretical formula to calculate responsive time of disturbance was presented here: t=-8.0645 In(1-M), where M is the death rate of population.
