Abstract: Tea green leafhopper, Empoasca onukii Matsuda, is one of the most widely distributed, ubiquitous, and destructive insect pests at tea plantations. This article reviews the research progress on the pest over the past decade in China. It encompasses the publications involving the dominant species identification, genetic relationships among populations, as well as the taxology, biological characteristics, and correlations with tea cultivars, climatic conditions, habitat management, and insecticide application of the insect. The remaining information gap and tasks on the studies of the pest and control are discussed with respect to the green development and the implementation of the policy on the “Regulations on the Control of Crop Pathogens and Pests.”
