Factor of the resistance to omethoate, dicofol, amitraz and pyridaben on -Tetranychus cinnabarinus- were 152.83, 55.59, 62.61, and 15.67 folds, respectively.

The relative specific activity of carboxylesterase were 2.06, 2.52, and 2.41, respectively. These results showed that increasing of the carboxylesterase activity is a one of biochemistry mechanisms of development of resistance to omethoate, dicofol, amitraz, pyridaben in -T. cinnabarinus.- In addition, the larger activity of the enzyme, the higher resistance folds on the spider mite.展开更多
