| ［目的］ 明确螺旋粉虱对不同甜椒品种的产卵偏好性及其与甜椒体内化学物质含量的关系。［方法］ 采用非自由选择法测定了螺旋粉虱对不同甜椒品种的产卵偏好性，并测定不同甜椒品种体内单宁酸、总黄酮、可溶性糖、可溶性蛋白等化学物质含量，分析其与螺旋粉虱产卵选择的相关性。［结果］ 螺旋粉虱对‘古风7号’的选择性最强，产卵量显著高于‘特大型牟一号’、‘吉星’、‘京椒’、‘特大甜椒八号’等8个品种（α=0.05水平），而与‘国禧205’、‘郑椒甜宝’、‘古风5号’等7个品种差异不显著。不同甜椒品种间的单宁酸含量、总黄酮含量、可溶性糖含量、可溶性蛋白含量存在显著差异。相关分析表明，螺旋粉虱对甜椒品种的选择性与单宁酸、总黄酮不相关，与可溶性蛋白呈负相关，与可溶性糖含量呈正相关。［结论］ 螺旋粉虱对不同甜椒品种的偏好性存在显著差异，这种差异与甜椒体内一些化学物质含量不同有关。 |

| ［Objective］ To understand the oviposition preference of Aleurodicus dispersus Russell and its relationship with the plant compounds extracted from different varieties of Capsicum annuum.［Method］ The oviposition preference of A. dispersus to different varieties of the sweet pepper, C. annuum, was studied by no free choice method. And the plant compounds extracted were detected. ［Result］ The most favorite pimientos variety was ‘Gufeng 7’. There was significant difference between ‘Gufeng 7’ and 8 other sweet pepper varieties, including ‘Tedaxingmouyihao’, ‘Jixing’,‘Jingjiao’ and ‘Tedatianjiaoba’. There was no significant difference between ‘Gufeng 7’ and the other 7 varieties, including ‘Guoxi205’ and ‘Zhengjiaotianbao’. The study showed that there was significant difference in the content of soluble sugars, proteins, tannin, flavone among different pimientoe varieties. ［Conclusion］ Correlation analysis indicated that the oviposition of A.dispersus was positively correlated with the content of soluble sugar in leaves, but it was not correlated with the content of soluble protein, tannin and flavone in leaves. |
