根据全国农技中心统一部署,2012年浙江省继续组织开展了褐飞虱、二化螟、灰飞虱等水稻害虫对常用药剂的抗性监测。监测结果表明,浙江省送样褐飞虱种群对吡虫啉仍维持在高水平抗性(252.0~1002.5倍),对噻嗪酮处于中等水平抗性(14.3~91.5倍),对噻虫嗪处于中等水平抗性(26.4~49.4倍),对烯啶虫胺、毒死蜱处于敏感阶段。与前两年相比,褐飞虱对吡蚜酮抗性上升速度很快,应引起各地高度重视。
According to the unified deployment of the national agricultural technology centers, in 2012, Zhejiang Province continued to organize the monitoring of the resistance of commonly used pesticides to rice pests including Nilaparvata lugens, Chilo suppressalis and Laodelphax striatellus. The results showed that the population of N. lugens in Zhejiang Province still maintained high levels of resistance to imidacloprid (252.0-1002.5 times), intermediate levels of buprofezin (14.3-91.5 times) and moderate levels of thiamethoxam Sex (26.4 ~ 49.4 times), nitenpyram, chlorpyrifos in a sensitive stage. Compared with the previous two years, the resistance of pymetrozine to Nilaparvata lugens (BSPH) increased rapidly and should be given high priority all over the country.
