摘　　要：昆虫不育技术是一种通过释放不育昆虫来控制田间害虫种群的生物防治新策略。为将昆虫不育技术应用于防治全球入侵害虫草地贪夜蛾Spodoptera frugiperda,该文对昆虫不育技术的作用机理和防治现状进行了综述,并对国内外利用该技术成功防治害虫的作用原理、作用方式和对多种害虫防治的成功案例进行了归纳;同时,对防治靶标基因doublesex的功能性作用进行总结。本综述基于CRISPR/Cas9基因编辑系统调控靶标基因,整理并展望通过释放携带显性致死基因的昆虫种群实现虫口密度控制的研究现状,为促进昆虫不育技术防治害虫提供理论基础。Sterile insect technology(SIT)is a novel strategy for biological control in the field by releasing sterile insects to reduce pest populations.To apply insect infertility technology to the prevention and control of the globally invasive pest Spodoptera frugiperda,this review provides a detailed explanation of the mechanism and status of insect infertility technology.It summarized the global use of SIT in pest control,including its principles,modes of action,and successful cases against various insects.In addition,this review provides a detailed analysis of the functional role of an important target gene for SIT,doublesex.Furthermore,it explores the potential of pest control through the release of insects carrying lethal genes based on CRISPR/Cas9 gene editing system,providing a theoretical basis for promoting the utilization of SIT for pest control.
