《环境昆虫学报》

昆虫作为真核生物界种类最多的类群，在长期的演化过程中，演化出了独特的生长发育方式。其中完全变态昆虫的一生包括卵、幼虫、蛹和成虫4个阶段。昆虫阶段性生长发育的激素和基因调控机理一直是昆虫学研究的重点和热点。近年来随着分子生物学理论和技术的不断发展，完全变态昆虫阶段性主控基因逐渐被鉴定出来。作为重大迁飞性农业害虫，草地贪夜蛾Spodoptera frugiperda自从2018年年底入侵我国以来，对我们国家的粮食安全产生了巨大的威胁。作为典型的完全变态昆虫，草地贪夜蛾幼虫需要从自然界摄取大量食物以便积蓄用于后期生殖和迁飞等生命活动。正是由于幼虫的暴食性，草地贪夜蛾对农业生产造成了巨大的危害。因此，本文综述完全变态昆虫阶段性发育主控基因的研究及其在草地贪夜蛾的研究进展，为基于生长发育调控的草地贪夜蛾高效绿色防控提供一定的理论依据。

英文摘要:

As the most species-rich group in the eukaryote, insects have evolved unique growth and development patterns during their long-term evolutionary process. Among these, holometabolous insects exhibit a life cycle comprising four distinct stages: egg, larva, pupa, and adult. The hormonal and genetic regulatory mechanisms underlying the staged growth and development of insects have long been a key focus and hot topic in entomological research. In recent years, with the continuous advancement of molecular biology theories and technologies, stage-specific master regulatory genes in holometabolous insects have been gradually identified. As a major migratory agricultural pest, the fall armyworm, Spodoptera frugiperda, has posed a significant threat to China's food security since its invasion of the country at the end of 2018. Being a typical holometabolous insect, fall armyworm larvae need to consume large quantities of food from nature to accumulate energy for subsequent life activities such as reproduction and migration. It is precisely this voracious feeding behavior of the larvae that has caused substantial damage to agricultural production. Therefore, this review summarizes the research progress on the stage-specific master genes in holometabolous insects, with a focus on S. frugiperda, aiming to provide a theoretical basis for the development of efficient and environment-friendly pest control strategies based on the regulation of insect growth and development.
