毒死蜱对赤子爱胜蚓的生长和繁殖的影响
如在本研究中，慢性毒性试验结果表明，毒死蜱对蚯蚓生长和繁殖有负面影响，但在很大程度上，这视乎于农药浓度和暴露周期。农药的浓度增加（表3），蚯蚓生长减慢。 经六周和八周的暴露期后，各控制处理组的生长各异，仅毒死蜱剂量为5mg / kg的除外。在八周的毒死蜱暴露期当中，蚯蚓的平均体重增加，一般都比控制处理组的为少。

原文如下：
Impacts of chlorpyrifos on growth and reproduction of E. fetida
As in the present study, results of chronic toxicity tests demonstrated that chlorpyrifos have adverse impact on growth and reproduction in earthworms, but this is largely dependent on pesticide concentration and exposure period. Earthworm growth decreased with increased concentrations of pesticide (Table 3). After 6 and 8 weeks of exposure, growth differed from the control in all treatments except for 5 mg/kg chlorpyrifos. The average weight gain of earthworms exposed to chlorpyrifos was generally lower than the controls during the eight-week exposure period.来自：求助得到的回答
