Abstract: Ectropis grisescens is a major pest in tea gardens，with wide distribution，rapid reproduction，and severe damage. To promote the green and sustainable development of the tea industry，following the principle of“ prevention first，integrated control”，it has become a trend to establish an integrated pest management（IPM）system centered on ecological regulation. This paper systematically reviews and discusses the latest research advances in four areas of Ectropis grisescens control：agricultural control，chemical control，physical control，and biological control. In terms of agricultural control，it focuses on preventive measures centered on optimizing the tea garden ecosystem and healthy cultivation. In chemical control，it summarizes the screening，application，and resistance management strategies of new，high⁃efficiency，and low⁃risk pesticides. In physical control，it emphasizes the use of Ectropis grisescens’s phototaxis to different wavelengths to develop composite⁃band LED light traps and optimize light intensity and deployment for precise and efficient ecological control. In biological control，it focuses on the optimization and field application of sex pheromone trapping technology，and comprehensively reviews the research and utilization of natural enemy insects，entomopathogenic microorganisms，and botanical pesticides. Based on this，the paper discusses the advantages and disadvantages of each technology，integrated application models，and challenges faced. It also looks forward to future research directions such as in⁃depth analysis of resistance mechanisms，development of intelligent monitoring and early warning technologies，and large⁃scale breeding of efficient natural enemies，to provide a systematic theoretical basis and practical reference for the scientific control of Ectropis grisescens and the green development of China’s tea industry.
