| 摘 要： | 通过分析历史资料、调查研究及田间试验，归纳了安徽省庐江县稻飞虱群落演变规律，分析了2006年褐飞虱发生特点、大发生成因，并提出相应的防治对策。1964年以来稻飞虱群落演变规律可分为4个阶段，其间相对于白背飞虱，褐飞虱种群数量分别为高、低、平、高水平，总态势近于“U”字形。当前褐飞虱发生特点主要有迁入虫源早、迁入量大，种群增量大，危害时间长，危害世代多，危害面积广。回升和暴发可能的原因包括水稻品种、作物布局和栽培措施改变，秋季气温升高，褐飞虱对吡虫啉产生抗药性，害虫天敌下降，以及农民防治组织缺乏。防治对策强调改进虫情测报、适时早治、适当多治、选用正确药剂、改进施药方法，并建立健全基层防治组织。

| Abstract: | From 1964 to 2006, the rice brown planthopper Nilaparvata lugens (Stl) population level formed a U shaped curve in Lujiang County, Anhui Province. The current pest status was characterized by earlier immigration and damaging generations, higher population levels, longer damage duration, more damaging generations and larger damaging areas. The possible causes of rebound and outbreaks may be related to great changes in varieties, cropping systems and cultivation practices, higher temperature in falls, pest resistance to imidacloprid, decrease in natural enemy and lack of control organizations. A control strategy is presented, emphasizing improved cultural and chemical measures, and establishment of community wide control organizations. |
