摘　　要：[目的]研究微生物对农药的降解效果。[方法]用双耐2号、亚热1号菌种降解10%吡虫啉和40%三唑磷,检测残留量,比较降解力。[结果]接种双耐2号和亚热1号后,发满菌丝1d吡虫啉在双耐2号、亚热1号中的残留量分别为4.00、9.60mg/kg,三唑磷在双耐2号、亚热1号中的残留量分别为19.43、19.06mg/kg,均与对照差异极显著。菌丝发满15d后,吡虫啉被双耐2号全部降解,在亚热1号菌种袋中含量为0.30mg/kg,明显低于三唑磷的18.50mg/kg。发满菌丝25d后吡虫啉被双耐2号、亚热1号完全降解,三唑磷在两种农药的残留量分别为3.41、3.09mg/kg,显著低于对照。2菌种对吡虫啉的降解力高于对三唑磷的降解力;双耐2号的降解力稍高于亚热1号。[结论]亚热1号和双耐2号菌种对吡虫啉和三唑磷有一定的降解力。Objective The research aimed to study the degradation effect of microorganism on pesticides.Method Shuangya 2 and Yare 1 strains were used to degrade 10 % midacloprid and 40 % triazophos to determine the residual amounts and compare the degradation abilities.Result After inoculating Shuangya 2 and Yare 1,the residual amounts of midacloprid in Shuangya 2 and Yare 1 were 4.00 and 9.60 mg/kg respectively after 1 d of full mycelium and that of triazophos were 19.43 and 19.06 mg/kg,which both had extremely significant differences with CK.Midacloprid was degraded by Shuangnai 2 entirely after 15 d of full mycelium and the content in the strain bag of Yare 1 was 0.30 mg/kg,being obviously lower than that of triazophos（18.50 mg/kg）.After 25 d of full mycelium,midacloprid was degraded by Shuangnai 2 and Yare 1 entirely and the residual amounts of triazophos in two pesticides were 3.41 and 3.09 mg/kg respectively being significantly lower than that of CK.The degradation abilities of 2 strains to midacloprid were higher than that to triazophos.The degradation ability of Shuangnai 2 was slightly higher than that of Yare 1.Conclusion Yare 1 and Shuangnai 2 had certain degradation abilities to midacloprid and triazophos.
