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.

摘要

采用刀切法和威尔科克森（盖汉）统计方法，在实验室研究了毒死蜱对朱砂叶螨种群动态的LC35亚致死效应。结果表明，在30℃±1℃、（70±15）%相对湿度和16L∶8D光周期条件下，毒死蜱处理组与对照组朱砂叶螨雌成螨寿命、F1孵化率和性别比无显著差异，但毒死蜱处理组的总产卵量（42.37±2.270）和内禀增长率（0.3279±0.0033）显著低于对照组（分别为52.50±2.433和0.3717±0.0043）。
