有关农业部门在南方水稻主产省设置28个监测点,监测褐飞虱对吡虫啉、噻嗪酮、吡蚜酮抗药性,监测二化螟对氯虫苯甲酰胺、氟苯虫酰胺、三唑磷抗药性。结果显示,褐飞虱对吡虫啉、噻嗪酮都已产生高水平抗性,与2013年相比褐飞虱对噻嗪酮抗性倍数大幅提升,抗性倍数都在100倍以上;对吡蚜酮处于中等至高水平抗性,据南京农业大学、广西区农科院植保所反映,与前几年相比,褐飞虱对吡蚜酮抗性水平上升很快,室内毒力测定0.2%的吡蚜酮死亡率不到20%。
The relevant agricultural departments set up 28 monitoring points in major rice-producing provinces in southern China to monitor the resistance of Nilaparvata lugens to imidacloprid, buprofezin and pymetrozine, and to monitor the resistance of chilo suppressalis to chlorantraniliprole, flubendiamide, triazophos Medicinal properties. The results showed that N. lugens had a high level of resistance to imidacloprid and buprofezin, compared with that of 2013, the resistance rate of BPH to buprofezin was significantly increased, with the resistance multiple more than 100 times; the pymetrozine was moderate to high Horizontal resistance, according to Nanjing Agricultural University, Guangxi Academy of Agricultural Sciences Plant Protection Institute reflects, compared with previous years, Nilaparvata lugens on pymetrozine resistance levels rose rapidly indoor toxicity determination of 0.2% pymetrozine mortality was not To 20%.
