中文摘要：
利用“T”形室观察了茶假眼小绿叶蝉Empoasca vitis Gothe对4种茶香精和3种寄主植物的趋性反应。结果表明，假眼小绿叶蝉对不同茶香精粉和寄主植物的趋性反应不同。叶蝉对绿茶和乌龙茶A香精有明显的趋向反应，而对乌龙茶B香精即铁观音茶香精则有明显的忌避反应，对红茶香精则无反应。假眼小绿叶蝉对茶梢和青菜的趋性反应无显著差异，而对茶梢和大豆的趋性反应有差异，表现出更喜好趋向茶梢。
英文摘要： The orientation response of false-eye leafhoppers, Empoasca vitis Gothe to four tea essences and three host plants was tested in a T-shaped chamber. Leafhoppers were highly attracted to both green tea essence and Oolong tea essence ‘A’ but were repelled by Oolong tea essence ‘B’, commonly, known as Tieguanyin. Black tea essence neither attracted nor repelled hoppers. Soybean seedlings were less attractive to E. vitis than tea but Chinese cabbage was as attractive as tea.
