| 中文摘要: |
| 褐飞虱Nilaparvata lugens Stal是危害水稻Oryza sativa L.的毁灭性害虫。种植抗虫水稻品种可以控制褐飞虱危害，技术手段绿色、经济且可持续。但是，褐飞虱致害性变异速度快且程度高，常导致抗虫水稻品种使用年限缩短。目前，针对褐飞虱致害性个体表型及分子标记、产生原因与机制、功能基因研究等已开展了大量研究。本文围绕褐飞虱致害性变异产生的遗传基础、分子标记、变异的主动机制和被动机制等方面进行综述，并对该领域未来方向进行展望。为更好地利用抗虫品种控制虫害，做好害虫的致害性监测及制定防治策略提供参考。 |
| 英文摘要: |
| The brown planthopper (BPH), Nilaparvata lugens Stal, is one of the most devastating pest of the most important food crop rice in the world. Using insect-resistant rice varieties to control brown planthopper infestation is green, economical and sustainable. However, due to the rapid and high degree of virulence mutation in BPH, the service life of insect-resistant rice varieties was shortened. At present, many scholars had carried out a large number of studies on the phenotypes and molecular markers, mechanisms, and functional genes of BPH virulence. In this paper, the genetic mechanisms, molecular markers, active and passive mechanisms of the virulence variation of BPH were reviewed, and the future direction of this research was also prospected. This review would be helpful for us to better control the pests by using the resistant varieties, to monitor virulence of pests and to develop control strategies. |
