| 摘 要： | 利用实验种群生命表和Morris-Watt模式综台评价了5个已推广的水稻品种对褐飞虱 Nilaparvata lugens Stal和白背飞虱Sogatetla furcifera Horvath的抗性及品种对稻飞虱各虫态的抗性作用大小。IR36、汕优6号、协优10号、秀水620和丙664对褐飞虱种群增长有明显的抑制作用；而品种秀水620、丙664和协优10号对白背飞虱呈中抗水平。同时发现，品种对稻飞虱各虫态抗性作用在成虫产卵期最明显，对褐飞虱表现为：成虫产卵期>卵孵化期>高龄(3-5龄)若虫期>低龄(1-2龄)若虫期；对白背飞虱则为：成虫产卵期>低龄若虫期>高龄若虫期>卵孵化期。

| Abstract: | The life table and Morris-Watt mathematical model were used as the methods of comprehensive evaluation to analysis the resistance levels of 5 rice varieties to brown planthopper (BPH) Nilaparvata lugens Stal and whitebacked planthopper (WBPH) Sogatella furcyera Horvath. The results showed that variety IR36, Shanyou 6, Xieyou 10, Xiushui 620 and Bing 664 had significantly inhibiting effects on the population growth of BPH, but variety Xiushui 620, Bing 664 and Xieyou 10 were moderately resistant to WBPH. The results also indicated that the ovipositional stage of adults of both BPH and WBPH was the key stage on which the resistant varieties had the most adverse influence. |
