摘　　要：草地贪夜蛾Spodoptera frugiperda是一种世界性重大农业害虫,在全球多个国家普遍发生,其幼虫可为害玉米、水稻等多种农作物。该虫于2019年初入侵我国,对我国农业生产构成了严重的威胁,防控形势严峻。为寻求一种草地贪夜蛾的绿色防控方法,本文对草地贪夜蛾潜在RNA干扰(RNA interference,RNAi)靶标致死基因、RNAi传统双链RNA(double-stranded RNA,dsRNA)递送技术的瓶颈以及纳米载体介导的RNAi技术应用进行概括,并对纳米载体介导的RNAi技术应用前景进行展望。The fall armyworm Spodoptera frugiperda is a major agricultural pest in many countries,which leads to the loss of many crops, such as corn and rice. Spodoptera frugiperda invaded China in early 2019 and has posed a serious threat to agricultural production, and the situation for its prevention and control is grim. In order to find an environment-friendly prevention and control measure for S. frugiperda, the potential RNA interference(RNAi) target lethal genes of S. frugiperda, the bottleneck of traditional double-stranded RNA delivery method were summarized, and the application of nanocarriermediated RNAi technology and the prospect of its application were forecasted in this review.
