摘要： 本文提出了一种检测及评价土壤生态系统中遗传毒性的新方法。赤子爱胜蚓( Eisenia f oetida) 经人工土壤法染毒,暴露于不同剂量的两种新型杀虫剂———呲虫啉和抑食肼中,观察它们对蚯蚓精子形态的影响。实验结果表明,呲虫啉在浓度大于0. 5mg/ kg 干土时对蚯蚓精子畸变率有明显影响( P < 0. 01) ,并呈现剂量效应关系;而抑食肼在浓度高达100mg/ kg 干土时,与对照组相比才有显著差异( P < 0. 05) 。

Abstract: In this paper, a new method to assess the environmental safety of pesticide has been proposed in terms of sperm deformity of the earthworm ( Eisenia f oetida) . The result s showed that the main sperm morphological deformity appeared to be shape changes of the sperm heads. Significant induction of sperm deformity ( P< 0. 01) and dose2effect relationship displayed when the earthworms were exposed to imidacloprid at the concent rations of more than 0. 5mg/ kg dry soil. However , The sperm deformity f requency of RH - 5849 - exposed groups did not show significant difference ( P < 0. 05) f rom the negative cont rol until the dose reached 100 mg/kg dry soil. This study suggest s that the detection of sperm abnormality in earthworms could provide an early warning system of polluted environment .

Key words: Imidacloprid, RH - 5849, Eisenia foetida, Sperm deformity test
