摘　　要：为了明确河北省不同地区棉蚜种群对主要杀虫剂的抗性水平及其发展趋势,采用浸渍法,于2014—2020年分别测定了河北省保定、沧州和邯郸地区棉蚜种群对6种杀虫剂的敏感性。结果表明:与国内历史敏感基线相比较,河北省棉蚜对高效氯氰菊酯、丁硫克百威、吡虫啉和氟啶虫胺腈的抗性均达到高抗至极高抗水平,抗性最高分别达到242、13353、1367和205倍;对氧乐果和噻虫嗪的抗性也达到中等至高水平抗性。应用Pearson相关性分析评估各药剂的logLC50值的相关性,发现保定种群对吡虫啉和氟啶虫胺腈(r=0.77,p=0.041)、噻虫嗪和氟啶虫胺腈(r=0.98,p<0.001)的抗性呈显著正相关;沧州种群对高效氯氰菊酯和丁硫克百威(r=0.81,p=0.027)、高效氯氰菊酯和噻虫嗪(r=0.90,p=0.006)、丁硫克百威和噻虫嗪(r=0.91,p=0.005)的抗性呈显著正相关;邯郸种群对高效氯氰菊酯和噻虫嗪(r=0.83,p=0.022)、高效氯氰菊酯和氟啶虫胺腈(r=0.97,p<0.001)、丁硫克百威和氟啶虫胺腈(r=0.77,p=0.045)的抗性呈显著正相关。本研究结果表明,河北省棉蚜种群对6种杀虫剂的抗性显著,且可能存在严重的交互抗性。To clarify the resistance level and development trend of different Aphis gossypii populations to main insecticides in Hebei Province,the susceptibility of A.gossypii from Baoding,Cangzhou and Handan to 6 insecticides was determined by dipping method during 2014-2020 in China.Comparing with the historical sensitivity baselines in China,the resistance of A.gossypii in Hebei Province toβ-cypermethrin,carbosulfan,imidacloprid and sulfoxaflor had all reached high or extremely high levels,with the highest resistance ratios of 242,13353,1367 and 205-fold,respectively.The resistance to omethoate and thiamethoxam were also reached medium or high resistance levels.Paired comparisons of the logLC50 values of insecticides tested for all the A.gossypii populations in Hebei Province showed that the resistance of Baoding population to imidacloprid and sulfoxaflor(r=0.77,p=0.041),thiamethoxam and sulfoxaflor(r=0.98,p<0.001)was significant positively correlated.The resistance of Cangzhou population toβ-cypermethrin and carbosulfan(r=0.81,p=0.027),β-cypermethrin and thiamethoxam(r=0.90,p=0.006),carbosulfan and thiamethoxam(r=0.91,p=0.005)was also significantly positive.Handan population also had a significant positive correlation betweenβ-cypermethrin and thiamethoxam(r=0.83,p=0.022),β-cypermethrin and sulfoxaflor(r=0.97,p<0.001),carbosulfan and sulfoxaflor(r=0.77,p=0.045).These results showed that A.gossypii population in Hebei Province had significant resistance to 6 insecticides and may have severe cross resistance.
