Degradation characteristics of parathion, parathion methyl and fenitrothion by a enzyme, extracted from the isolated strain YF11, was determined. 从降解菌YF11中提取了降解酶并测定了该降解酶对对硫磷、甲基对硫磷和杀螟松的降解特性。
Besides methyl parathion, MPH can also degrade fenitrothion, parathion, chlorpyrifos in degressive hydrolytic efficiency in turn. 甲基对硫磷水解酶(MPH)除了可以降解甲基对硫磷外,还可以降解杀螟松,乙基对硫磷,毒死蜱,但降解效率依次降低。
It suggested that resistance to fenitrothion was partially associated with multiple function oxidase ( MFO). 这表明了多功能氧化酶(MFO)活性增强,而似乎与水解酶的活性无关。
With the method of probit analysis, we estimated the realized heritability ( h2) of resistance to fenitrothion in the rice stem borer ( Chilo suppressalis Walker). 应用数量遗传学的方法分析了水稻二化螟(Chilosuppressalis)对杀螟硫磷抗药性的遗传力,并就遗传力和杀虫剂的杀死率对抗性发展速率的影响进行了预测。
Study on environmental estrogenic activity of fenitrothion in vitro and its mechanism 杀螟硫磷体外环境雌激素活性及机制研究
Fenitrothion residues in early season rice/ fish/ azolla ecosystem had little effect on the next paddy field. 早季稻-鱼-萍生态系中残留的杀螟硫磷对后季稻田几乎无影响。
Seven kinds of clay powder: attapulgite, halloysite, bentonite, diatomite, kaolin, talc and rice-hull ash were soaked in the protectant Solutions: malathion, fenitrothion and pirimiphos methyl. 七种粘土粉末:硅镁土、埃洛石粉、膨润土、硅藻土、高岭土,滑石粉和稻壳灰被三种储粮保护剂:马拉硫磷、杀螟松和虫螨磷溶液浸泡。
Conclusion Fenitrothion has environmental estrogenic activity which was mediated by ER. 结论杀螟硫磷具有环境雌激素活性,其拟雌激素作用由ER介导而产生。
