| 摘 要： | 针对我国2005年水稻褐飞虱暴发成灾,从药剂使用角度分析了我国褐飞虱成灾的原因。外来虫源大量迁入、种植制度和水肥管理对褐飞虱有利、农药的诱导作用是3大主要因子。农药诱导褐飞虱猖獗主要包括对非靶标生物的杀伤、施药技术不尽合理、药剂品种使用不当、耐药性或抗药性增加等因子。 |
| 关 键 词： | 水稻褐飞虱 抗药性 害虫再猖獗 |

| Abstract: | The factors affecting the outbreak of the brown planthopper(BHP),Nilapavata lugens Stl,were reviewed.The mixture of migratory BHPs from abroad and local population resulted in the failure of chemical control.The insecticide-induced resurgence played an important role in the failure of chemical control in 2005,which had several possible mechanisms,including physiological enhancement of pest fecundity,reduction in herbivore-herbivore competition,increase in pest resistance to insecticides,alteration of host plant nutrition,killing of natural predators and parasites of the pest and irrational spraying techniques. |
| Keywords: | Nilapavata lugens Stal insecticide resistance pest resurgence |
