摘　　要：采用浸叶法在室内测定了采自中国陕西省(陕)长安区、华阴县、三原县、兴平市和山西省(晋)太谷县5个地区的粘虫田间种群对6种常用杀虫剂的抗药性。结果表明:5个地区粘虫种群对甲氨基阿维菌素苯甲酸盐(以下简称甲维盐)均表现为敏感,抗性倍数(RR)为0.6~1.6;对氯虫苯甲酰胺和高效氯氰菊酯为敏感至低水平抗性,RR为0~6.2;对高效氯氟氰菊酯和毒死蜱为敏感至中等水平抗性,RR为0.1~32.8;对辛硫磷,除陕西省三原县种群表现为敏感外,其他4个种群均表现为中等至高水平抗性,RR为19.4~70.1。药剂毒力相关性分析表明,毒死蜱和甲维盐之间存在显著相关性,氯虫苯甲酰胺与甲维盐、毒死蜱及辛硫磷之间不存在明显的相关性。因此陕晋两省上述地区的粘虫防治推荐选用甲维盐、氯虫苯甲酰胺和高效氯氰菊酯,同时应注意将氯虫苯甲酰胺和甲维盐、毒死蜱等轮换使用,以延缓抗药性的产生和发展。Resistance of five field populations of Mythimna separata （Walker）, which collected respectively from Chang＇an district, Huayin county, Sanyuan county, Xingping city in Shaanxi province and Taigu county in Shanxi province of China, to six insecticides was evaluated by leaf dip method in laboratory. The results showed that the populations ofM. separata in those five areas were relatively sensitive to emamectin benzoate （resistance ratio 0.6-1.6 fold）. In terms of chlorantraniliprole and beta- cypermethrin, those five field populations ofM. separata showed susceptible to low level resistance （RR 0-6.2）. Compared with the relative susceptible strain ofM. separata, those five field populations showed susceptible to moderate resistance level to chlorpyrifos and lambda-cyhalothrin （RR O. 1-32.8）.Resistance to phoxim was moderate to high level in all the tested populations （RR 19.4-70.1） except for the Sanyuan population. Pair-wise correlation analysis among different insecticides indicated that chlorpyrifos has a positive and significant correlation with emamectin benzoate. However, chlorantraniliprole has no significant correlation with emamectin benzoate, chlorpyrifos or phoxim. Therefore, emamectin benzoate, chlorantraniliprole and beta-cypermethrin were recommended for the control of oriental armyworm. Meanwhile, to delay the generation and development of insecticide resistance in Shaanxi and Shanxi province, rotational application of insecticides between chlorantraniliprole and emamectin benzoate or chlorpyrifos is necessary.
