2008年全国农业技术推广服务中心组织辽宁、河北、山东、山西、陕西、河南、江苏、安徽、湖北、江西、新疆、海南、广西、福建、浙江、云南等省(自治区)65个抗药性监测点对褐飞虱、二化螟、棉铃虫、棉蚜的抗药性进行了监测。根据目前抗性划分的一般标准,即抗性比低于5倍的为相对敏感,5～10倍为低抗,10～40倍为中抗,40～160倍为高抗,>160倍为极高水平抗性,测定了吡虫啉等12种农药。现就抗
In 2008, the National Agricultural Technology Extension Service Center organized 65 drug resistance surveillance programs in Liaoning, Hebei, Shandong, Shanxi, Henan, Jiangsu, Anhui, Hubei, Jiangxi, Xinjiang, Hainan, Guangxi, Fujian, Zhejiang and Yunnan provinces Point on the brown planthopper, Chilo suppressalis, cotton bollworm, cotton aphid resistance were monitored. According to the current general criteria for resistance partitioning, resistance is less than 5 times less sensitive, 5 to 10 times less resistant, 10 to 40 times more resistant, 40 to 160 times more resistant,> 160 times more Very high level of resistance, determination of imidacloprid and other 12 kinds of pesticides. Now on the anti
