摘要: The citrus red mite, Panonychus citri, a major pest distributed worldwide, has evolved severe resistance to various classes of chemical acaricides/insecticides including pyrethroids. It is well known that the pyrethroids mainly caused by point mutations voltage-gated sodium channel gene in wide range pests. However, increasing number evidences support might also be resulted from integrated mechanisms metabolic mechanisms. In this study, firstly, comparative analysis RNA-seq data showed multiple detoxification genes, GSTs PcGSTd1, were up-regulated fenpropathrin-resistant population compared with susceptible strain (SS). Quantitative real time-PCR results exposure fenpropathrin had an induction effect on transcription PcGSTd1 time-dependent manner. vitro inhibition and assay recombinant found not metabolized directly protein. its antioxidant role alleviating oxidative stress was demonstrated via reversely genetic experiment. Our provide list candidate genes which may contribute implicated evolution field P. citri. Furthermore, during process, plays detoxifying lipid peroxidation products induced fenpropathrin.
