测试的结果在图2中显示。暴露在毒死蜱对蚯蚓的繁殖有显著的影响。 暴露四周后,处于所有不同的控制处理,蚓茧数目有差异,仅毒死蜱剂量为5mg / kg (P<0.05)除外。然而,八周后,暴露在5mg / kg毒死蜱的蚓茧产量比处理组(P<0.05)显著降低。相比于暴露在毒死蜱四周,暴露达八周的蚓茧产量下降。
蚓茧的生存能力的结果在图3中显示。暴露四周后,相比于对照组,暴露于杀虫剂的蚓茧的存活率显著6较低,仅毒死蜱剂量为5mg / kg (P<0.05)除外。只因蚓茧产量非常低,故并未对暴露在毒死蜱达八周的蚓茧的生存能力作评估。

原文如下:
Results of the reproduction test were presented in Fig.2. Chlorpyrifos exposure had a significant effect on reproduction in earthworms. After four weeks of exposure, number of cocoons differed from the control in all treatment except for 5 mg/kg chlorpyrifos (P<0.05). However, after 8 weeks, cocoon production was significantly lower at 5mg/kg chlorpyrifos than the controls (P<0.05). Cocoon production in earthworm exposed to chlorpyrifos for 8weeks was lower than that for 4 weeks.
The results of the viability of cocoons are presented in Fig.3. After four weeks of exposure, viability of cocoons from earthworms exposed to pesticides was significantly lower than the controls except for 5 mg/kg chlorpyrifos (P<0.05). Cocoon viability in earthworm exposed to chlorpyrifos for 8 weeks was not evaluated due to very low cocoon production.来自:求助得到的回答
