摘要: 用TN1、N22、AsD7和Ptb33等4个抗虫性差异明显的水稻品种测定了褐飞虱和白背飞虱在它们上面的栖息率、落卵量、卵存活率、若虫存活和发育状况,以及后代种群数量表现.结果表明,Ptb33通过减少2种飞虱的栖息率、落卵量,降低卵和若虫存活率,延长若虫的发育时间,抑制后代的种群数量增长,表现出明显的抗性.N22对白背飞虱、AsD7对褐飞虱的后代种群建立与发展均表现明显的抑制作用.2种飞虱在TN1上,以及褐飞虱在N22上和白背飞虱在AsD7上,种群发展较快.这可能与这4个品种对各自所作用的飞虱在栖息率、落卵量、卵存活率、若虫存活和发育状况影响不大有关.文中讨论了2种飞虱种群数量变化与水稻品种更替的关系,指出了利用水稻品种抗性抑制稻飞虱种群增长的可能性.

Abstract: The effect of rice varieties with different insect resistance on dynamics of Nilaparvata lugens and Sogatella furcifera population was examined,based on the investigation of their inhabiting ratio,egg amount, survival rate of egg and nymph,nymph development,and the amount of their offspring population.Four rice varieties,TN1,N22,AsD7 and Ptb 33 were investigated.Ptb 33 had a significantly lower inhabiting ratio, egg amount,and survival ratio of eggs and nymphs of both parasitic populations,a prolonged development time from nymphs to adults,and an inhibited offspring population, indicating an evident resistance of this host variety.N22 and AsD7 inhibited the development of offspring S. furcifera and N. lugens, respectively.The parasitic populations of S. furcifera and N. lugens developed more rapidly on TN 1,compared with N.lugens population on N22 and S. furcifera on AsD7. The relationship between the quantitative dynamics of both population and rice variety replacement was discussed,and the possibility of using resistant rice varieties to control these two insect populations was also analyzed.
