通过分析江苏省南通市通州区2005年~2010年褐飞虱田间系统调查资料,总结出了近年来沿江稻区褐稻虱迁入期提前、峰次多,以及短翅成虫始见早、后期补充迁入量大的发生特点,进而分析得出水稻生长后期褐飞虱暴发的主要原因是前期繁殖虫源量大、暖秋气候及生育期延长、害虫产生抗药性等。据此提出了强化测报、治前控后、综合防治的控制对策。
Based on the investigation of the brown planthopper field data from 2005 to 2010 in Tongzhou District, Nantong City, Jiangsu Province, the results showed that in recent years, the migration of brown planthopper in the Yangtze River rice area in advance, the second highest frequency, and the short- The main reason for the outbreak of brown planthopper in the later stage of rice growth is the large amount of insect source, the warm autumn climate and growth period, the resistance of pests and so on. Based on this, we put forward some countermeasures for comprehensive prevention and control after strengthening forecasting and pre-treatment control.
