Differential metabolism of neonicotinoids by Myzus persicae CYP6CY3 stably expressed in Drosophila S2 cells

抄録

The peach-potato aphid, Myzus persicae, is a serious crop pest that has developed imidacloprid resistance, mainly through overexpression of CYP6CY3. Here, we established a metabolic assay using Drosophila S2 cells that stably expressed CYP6CY3. We found that CYP6CY3 showed metabolic activity against imidacloprid, as well as acetamiprid, clothianidin, and thiacloprid, but had no activity against dinotefuran. Our study suggested that stable gene expression in Drosophila S2 cells is useful for examining which insecticide is metabolized by P450 monooxygenases.
