| 摘 要： | 采用Jackknife统计推断技术和生存分析Wilcoxon (Gehan)技术，对寄主为桑树的朱砂叶螨种群水平上的亚致死效应进行了研究.结果表明, 在30 ℃±1 ℃、RH (70±15)%、16L∶8D条件下,朱砂叶螨卵受毒死蜱亚致死剂量LC35处理后，雌成螨寿命、子代卵孵化率、性比与对照组无显著差异，而处理组每雌总产卵量(42.37±2.270)显著低于对照组(52.50±2433)；处理组内禀增长率(0.3279±0.0033)显著低于对照组(0.3717±0.0043)

| Abstract: | By using Jackknife technique and Wilcoxon (Gehan) statistic method, the LC35 sublethal effect of chlorpyrifos on the population dynamics of Tetranychus cinnabarinus was studied in laboratory. The results showed that under the conditions of 30 degrees C +/- 1degrees C, (70 +/- 15) % RH and a photoperiod of 16L: 8D, there were no significant differences in the longevity of female adult, F1 hatchability, and sex ratio of T. cinnabarinus between chlorpyrifos treatment and the control, but the total oviposition (42.37 +/- 2.270) and the intrinsic rate of increase (0.3279 +/- 0.0033) in chlorpyrifos treatment were significantly lower than those (52.50 +/- 2.433 and 0.3717 +/- 0.0043, respectively) in the control. |
