摘　　要：采用体内染毒的方法,研究了克百威和乙霉威对家蝇幼虫体内乙酰胆碱酯酶(AChE)活性的影响,对以AChE活性抑制率作为生物学标记物来检测环境中农药残留的可行性进行了初步探讨.结果表明,同一时间内,对AChE活性的抑制率随着农药浓度的升高而增加;农药处理后,随着时间的延长,对AChE活性的抑制率逐渐降低.AChE活性抑制率可以作为生物学标记物.The influence of carbofuran and dirthofencarb on internal acctylcholinesterase (AChE) activity in housefly larvae were studied adopting internal toxic pollution technique; and the possibility of using AChE activity as a biomarker to monitor the pesticide residue in environment was explored prelimilarily. The inhibition rate of AChE activity increased with increase of the concentration of pesticide at the same time. The inhibition rate of AChE activity decreased gradually with the time after pesticide treatment. The AChE activity might be used as an biomarker.
