毒死蜱对中国石龙子胚胎发育及孵出幼体表型的影响

摘要

采用中国石龙子作为动物模型，研究有机磷农药毒死蜱对其胚胎发育及幼体生长的影响．结果表明，1．2 mg／g的毒死蜱完全抑制石龙子胚胎的发育，0．12 mg／g处理组卵孵化成功率显著低于对照组．相对于对照组，0．12 m g／g处理组卵孵化期无显著影响，孵出幼体个体显著较小、运动能力较差，但饲养一个月的存活率和日生长速率无显著差异．%Taking Chinese skink (Plestiodon chinensis)as the animal model ,the effects of organophosphorus pesticide chlorpyrifos on embryonic development and hatchling phenotypes are studied . The results indicate that 1 .2 mg/g high concentration of chlorpyrifos seriously inhibits embryonic development ,and egg hatching success of 0 .12 mg/g treated group is significantly lower than that of the control group .The incubation period of 0 .12 mg/g treated group is not different from the control group .However ,the hatchlings from 0 .12 mg/g treated group are significantly smaller and performed worse than those from the control group .In the first month ,hatchling survival rate and grow th rate have no significant difference .
