不同水稻品种对白背飞虱取食和产卵选择性的影响

为进一步了解抗虫品种对白背飞虱的抗性机制,运用标准苗期群体鉴定法、蜜露测定法等方法,研究了8个不同抗性水平水稻品种对白背飞虱Sogatella furcifera（Horváth）取食和产卵选择性的影响。结果表明,水稻品种IR54751-2-34-10-6-2、MR1532、Rathu Heenati表现为高抗;IR54742-1-18-12-11-2、IR71604-4-1-4-10-8-5-3-1表现中抗;IR72表现为中感;BG367-7、TN1表现为高感。白背飞虱对MR1532、IR54751-2-34-10-6-2和Rathu Heenati上的取食趋性较弱,这几个品种对白背飞虱取食...

Summary:为进一步了解抗虫品种对白背飞虱的抗性机制,运用标准苗期群体鉴定法、蜜露测定法等方法,研究了8个不同抗性水平水稻品种对白背飞虱Sogatella furcifera（Horváth）取食和产卵选择性的影响。结果表明,水稻品种IR54751-2-34-10-6-2、MR1532、Rathu Heenati表现为高抗;IR54742-1-18-12-11-2、IR71604-4-1-4-10-8-5-3-1表现中抗;IR72表现为中感;BG367-7、TN1表现为高感。白背飞虱对MR1532、IR54751-2-34-10-6-2和Rathu Heenati上的取食趋性较弱,这几个品种对白背飞虱取食量的影响最大;MR1532、Rathu Heenati和IR54751-2-34-10-6-2上的卵量显著少于产在对照品种TNI的卵量,IR54742-1-18-12-11-2、IR71604-4-1-4-10-8-5-3-1、IR72上的卵量与产在对照品种TNI上的卵量差异不显著。白背飞虱在抗虫品种上并非完全不取食,只是抗性越强取食量越少;抗性表现为抗的品种对白背飞虱成虫产卵选择性有明显影响。

In order to further understand the resistance mechanisms of rice variety to white-backed planthopper, Sogatella furcifera （ Horv＆#225;th） （ WBPH） , population group detection and honeydew quantity detection methods were used to study the effects of eight rice varieties on feeding and oviposition preference of WBPH. The results showed that MR1532 , IR54751-2-34-10-6-2 and Rathu Heenati were resistant to WBPH, these resistant rice varieties affected the feeding of WBPH strongly. The egg number on MR1532, or on Rathu Heenati and IR54751-2-34-10-6-2 was significantly less than that on TN1. The egg number on IR54742-l-18-12-11-2 , or on IR71604-4-l-4-10-8-5-3-l and IR72 was not significant difference from that on TNI. WBPH did not never suck on resistant rice varieties, but the stronger the resistance of rice varieties are, the less feeding amount the WBPH takes. The resistant rice varieties significantly affect the oviposition pref
