摘　　要：为明确华北棉区棉铃虫Helicoverpa armigera田间种群对3种常用杀虫剂的抗性,于2014—2015年和2018—2019年分别采集河南、河北、山东和山西4个省的棉铃虫田间种群,采用浸叶法于室内测定棉铃虫对辛硫磷、三氟氯氰菊酯和甲维盐的抗性水平。结果表明,各监测点棉铃虫对辛硫磷处于中等水平抗性,在2014—2015年和2018—2019年的抗性倍数分别为13.0~58.5倍和21.1~55.3倍,棉铃虫对辛硫磷的抗性发展相对缓慢;各监测点棉铃虫种群对三氟氯氰菊酯已产生中等至高水平抗性,并呈现逐年上升的趋势,其中河北沧县、河南安阳、山西盐湖种群的抗性倍数由2014年的61.0倍、22.5倍和24.0倍上升至2019年的91.1倍、44.7倍和61.3倍,山东夏津种群的抗性最高,2019年抗性倍数达到216.3倍;棉铃虫种群对甲维盐表现为低至中等水平抗性,河北沧县、河南安阳、山西盐湖和山东夏津种群的抗性倍数分别为8.2~40.4倍、5.8~16.6倍、5.5~23.4倍和11.0~36.6倍。表明4个监测地区的棉铃虫田间种群对3种杀虫剂已经产生了不同程度的抗性,建议减少这3种杀虫剂的使用频次,并注意与其他杀虫剂交替轮换使用,以延缓棉铃虫抗药性的发展。To understand the resistance level of Helicoverpa armigera populations collected from different cotton regions of north China to three insecticides, phoxim, cyhalothrin, and emamectin benzoate,the field populations of H. armigera collected from Henan, Hebei, Shandong and Shanxi provinces were evaluated using leaf dipping methods in the laboratory in 2014—2015 and 2018—2019. The results showed that H. armigera populations from the four provinces had developed medium-level resistance to phoxim, with resistance ratios ranging from 13.0 to 58.5 folds in 2014—2015 and 21.1 to 55.3 folds in 2018—2019, respectively. It indicated that the resistance of H. armigera to phoxim developed slowly in recent years. The filed populations of H. armigera showed medium-to high-level resistance to cyhalothrin. The resistance ratios of populations from Cangxian of Hebei, Anyang of Henan and Yanhu of Shanxi increased from 61.0, 22.5 and 24.0 folds in 2014 to 91.1, 44.7 and 61.3 folds in 2019, respectively. The highest resistance to cyhalothrin was detected in the population from Xiajin of Shandong with a resistance ratio of 216.3 folds in 2019. H. armigera populations in the four provinces had developed low-to medium-level resistance to emamectin benzoate. The resistance ratios of populations from Cangxian of Hebei, Anyang of Henan and Yanhu of Shanxi and Xiajin of Shandong ranged between 8.2-40.4, 5.8-16.6, 5.5-23.4 and 11.0-36.6 folds, respectively. The results suggested that the four H. armigera populations had developed different levels of resistance to the three insecticides. Therefore, excessive use of phoxim, cyhalothrin and emamectin benzoate should be avoided. Insecticides should be used in rotation with other types of insecticides to delay the development of insecticide resistance in field populations of H. armigera.
