The nine tested tea cultivars were categorized into three groups by cluster analysis according to the number of probes per insect, waveform durations, or duration per probe including various waveforms on different tea cultivars. Waveforms S, E and F correlated to the main feeding activity of the leafhoppers and may provide valuable information on predicting the resistance levels of the tea plants to the leaThopper. The resistance level of the nine tea cultivars to the leafhopper was ranked based on the durations of waveform S, E and F, as well as the duration every probe including various waveforms.

以该叶蝉在不同品种茶树上的平均刺探次数和各波形平均持续时间为指标，或者以其在不同品种茶树上含有各波形的单次刺探平均持续时间为指标，分别进行聚类分析，均将9个品种分为3个不同的组。S、E和F波对应着假眼小绿叶蝉在茶树上的主要取食活动，可能与茶树抗假眼小绿叶蝉的取食密切相关。
