摘要: 利用网罩法测定了假眼小绿叶蝉不同虫口密度对茶鲜叶产量及受害指数的影响。在此基础上,建立了不同虫口密度与茶鲜叶经济损失率线性回归方程。根据目前茶叶的生产情况,制定了绿茶和乌龙茶不同茶区、茶季、茶鲜叶价格水平下假眼小绿叶蝉相应的防治指标。

Abstract: Effect of different densities of Empoasca vitis on the yield loss rate and the damage indexes of fresh tea leaves were evaluated with the net method. Based on the results, the linear correlation equation was obtained for analysis on pest densities and economic loss rate of fresh tea leaves. The economic threshold of the pest for oolong tea and green tea at different areas, tea seasons and fresh tea prices was put forward

Key words: Empoasca vitis Gothe, Economic Threshold, Tea
