而甲基毒死蜱、毒死蜱、甲基嘧啶磷、马拉硫磷、op′-DDE、pp′-DDE、α-六六六等农药则对不同基质显示了相对较弱的基质依赖特点。

In addition , some pesticides , such as methyl-chlorpyrifos , chlorpyrifos , methyl-pirimiphos , malathion , op ' - DDE , etc. , show relative high stability in various matrixes .

并且发现，氯氰菊酯在水溶液中的水解速率远比马拉硫磷慢，但pH和温度对二者的水解效应相似，证明氯氰菊酯的水解机制与马拉硫磷相同，属于亲核反应。

AS the hydrolysis rate of cypermethrin was increased with the raising of pH and temperature as that of malathion , it proved that the hydrolysis mechanism of cypermethrin , the same as that of malathion , was nucleophilic reaction .

结果表明：在Pgm基因座上，马拉硫磷对具有不同基因型的中华稻蝗个体存在选择性致死作用，但是在Me基因座上未观察到类似选择性致死作用。

The selective lethal effects were observed among the genotypes at Pgm locus but not at Me locus .

根据AChE的敏感性及其对有机磷农药的线性响应程度，鲅鱼脑AChE适于作为监测马拉硫磷和甲基对硫磷酶传感器的指示酶。

Based on the sensitivity of AChE and its linear correlation to Ops , the AChE from S.niphonius is suitable to be used as the indicator enzyme of enzyme biosensor to monitor malathion and parathion-methyl .

研究褐飞虱对马拉硫磷的抗性与其体内酯酶活性关系的结果表明，羧酸酯酶抑制剂TPP对马拉硫磷的增效作用随着褐飞虱对马拉硫磷抗性水平的提高而增加。

The relation between malathion-resistance and esterases in brown planthopper was studied . The results indicated that , with the increase of resistance of brown planthopper to malathion , the synergized action ( TPP ) of carboxylesterase 's increased .

研究了固相微萃取（SPME）和二氧化锡气体传感器的联用技术对果蔬中有机磷农药残留乐果、氧乐果、甲胺磷、乙酰甲胺磷、马拉硫磷、敌百虫等的快速检测。

两个种群酶活性的差异与马拉硫磷半致死剂量（LD50）的差异很相近，这提示酯酶活性的提高在东亚飞蝗对马拉硫磷的抗性中起一定的作用。

The difference of LD_ ( 50 ) value for malathion between the two populations was consistent with the difference of esterase activities , suggesting that general esterases contributed to the malathion resistance of the two populations .
