摘　　要：为了有效控制褐飞虱的暴发危害,进行了抗性品种对褐飞虱自然诱发抗性试验研究,结果显示,在第三代以白背飞虱为优势种群时,抗性品种自然诱发对白背飞虱无明显抗性。在第四代以褐飞虱为优势种群时,不同抗性品种对褐飞虱自然诱发抗性差异显著,抗性品种对褐飞虱自然诱发抗性在降低低龄若虫量的同时抑制了低龄向高龄转化。In order to control the invasion of brown planthopper,which was the main insect pest in cultivated rice,the resistant cultuvated varieties were applied for natural inductive experiments.The results indicated that the cultivated rice had no obvious resistance to white backed planthopper as in the 3rd generation.However,when confronted brown planthopper as dominant species,prominent resistant differences were demostrated among different breeds.In addition,the natural inductive resistance of these varieties can suppress the transition from young to old stage of Brown planthopper along with an decreased number of immature inseets.
