摘要
2005年褐飞虱Nilaparvata lugens(Stal)在吴江市稻区后期特大发生。在总结其发生特点的基础上,分析特大发生的原因,主要与后期成虫迁入量大、气候及苗情适宜、褐飞虱对吡虫啉产生高水平的抗药性、残留基数高以及用药质量差等因素有关,最后提出了积极开展综合防治、加强监测以及科学使用农药等治理措施。
The outbreak of later brown plant hopper appeared badly in rice fields in Wujiang city in 2005. The causes were analyzed based on the summation of the occurrence characteristic of brown plant hopper. Results showed that the outbreaks were correlated with some factors such as large amounts of immigrant adults and survival insects, suitable climate and seedlings, high resistant level of brown plant hopper to Imidacloprid, unsuccessful spray and so on. Finally the control strategies were put forward： actively developing the integrated control measures, strengthening pest monitoring, and applying pesticides scientifically.
