Core Viewpoint - The prediction indicates that the tea leafhopper (Empoasca onukii) is expected to reach a severe outbreak level in Qingyuan, Guangdong by 2025, based on data from the national tea pest monitoring system [3][4]. Group 1: Pest Monitoring and Impact - The tea leafhopper is known to have over 10 generations in Guangdong each year, with peak damage occurring in the summer and autumn seasons [7][10]. - During the first peak in 2025, tea gardens in Qingyuan will need to focus on preventing the risk of pest outbreaks [8]. Group 2: Pest Control Strategies - **Ecological Regulation**: Implementing timely and batch harvesting, light pruning after spring tea, and controlling weed growth can help manage pest populations [15][16]. - **Physical and Chemical Control**: Hanging pest-friendly color boards can significantly reduce the number of leafhoppers during the first peak, and using insect traps can help capture adults and nymphs [17][18]. - **Scientific Pesticide Use**: When the pest population exceeds six individuals per leaf, specific pesticides such as tea saponin and pyrethroids can be used, ensuring adherence to safety intervals and minimizing application frequency [19][20][21]. Group 3: Technical Support - The pest control strategies are supported by various agricultural research institutions in Guangdong, including the Guangdong Modern Agricultural Industry Technology System and the Guangdong Academy of Agricultural Sciences [22][23].
