The impact of Methyl parathion and Carbaryl was evaluated on an ecologically important soil Collembola, Cyphoderus sp. Enzyme characteristics demonstrate substrate optimum at 1 10(-2) mol/L temperature optimum at 30 degrees C with a pH requirement of 8.0. In vivo inhibition of whole body AChE reveals higher degree of inhibition by LD50 dose of Methyl parathion as compared to that of Carbaryl where maximum inhibition was noticed at the agricultural dose.
评估了甲基对硫磷和西维因对一种具有生态重要性的土壤弹尾虫——Cyphoderus sp.的影响。酶特性表明，底物最适浓度为1×10⁻²mol/L，最适温度为30℃，pH要求为8.0。体内对全身乙酰胆碱酯酶（AChE）的抑制作用显示，与西维因相比，甲基对硫磷的LD50剂量具有更高程度的抑制作用，西维因在农业剂量下观察到最大抑制作用。
