  朱砂叶螨(Tetranychus cinnabarinus)是棉花、蔬菜等经济作物上最重要的害螨之一.该螨的防治多年来一直以施用化学农药为主,导致其抗药性发展十分迅速.抗性监测数据表明,我国多个地区的朱砂叶螨已对甲氰菊酯等多种杀虫杀螨剂产生了不同程度的抗性.GSTs作为重要的解毒代谢酶,主要功能是催化一些内源性或外来有害物质的亲电子基团与还原型谷胱甘肽的巯基结合,增加其疏水性使其易于排出体外,从而达到解毒的目的.此前的研究发现,朱砂叶螨多个Mu家族的GST基因在甲氰菊酯抗性品系中的表达具有可诱导性,可能与该螨对甲氰菊脂的抗性有关.在此基础上,本研究以其中的TcGSTM7基因为主要对象,通过RNAi和原核表达的方法分析其在朱砂叶螨抵抗甲氰菊脂中的作用.
