3 种蚜虫的平均刺探次数均大于在早小洋菊 上的平均刺探次数.聚类分析结果显示, 2个主栽品种之间抗性存在差异.早小洋菊顶叶平均可 溶性糖和可溶性蛋白含量分别为2.71 mg/g和25.36 mg/g, 均高于晚小洋菊;

早小洋菊顶叶总酚含量 为0.24 mg/g, 显著低于晚小洋菊;

早、 晚小洋菊总黄酮含量分别为3.46 mg/g和3.37 mg/g.早小洋 菊顶叶可溶性糖、 可溶性蛋白含量基本上与每种菊蚜的E

The results showed that the durations of E1 and E2 waves in M. sanborni on the cultivar Wanxiaoyangju (4.31 min and 3.47 min, re- spectively) were shorter than those on the cultivar Zaoxiaoyangju (4.63 min and 3.75 min);

the dura- tions of E1 and E2 waves in A. gossypii and M. persicae were 4.32, 4.72 min and 4.92, 4.64 min, respec- tively. The average numbers of probes of the three aphids on Wanxiaoyangju were higher than those on 基金项目: 浙江省自然科学基金项目 (LY17C140002) , 浙江省大学生科技创新项目 (2017R409055) * 通信作者(Author for correspondence) , E-mail: han-insect@263.net 收稿日期: 2018-02-18
