摘　　要：用胃毒触杀联合毒力法监测了山东省7个韭菜种植区的韭蛆种群对毒死蜱、辛硫磷、高效氯氰菊酯、高效氯氟氰菊酯、吡虫啉和噻虫嗪6种常用杀虫剂的抗性水平。结果表明:山东省各地区韭蛆种群对毒死蜱和辛硫磷的抗性已较为普遍,其中莘县种群对毒死蜱的抗性超过30倍;对高效氯氰菊酯的抗性为中等水平;泰安种群对供试的两种菊酯类药剂均产生了低水平抗性;而对吡虫啉和噻虫嗪,7个供试种群处于敏感或敏感性下降状态。The levels of resistance to six commonly used insecticides, chlorpyrifos, phoxim, beta-cypermethrin, larnbda-cyhalothrin, imidacloprid and thiamethoxam were determined in seven populations of Bradysia odoriphaga collected from Shandong Province by stomach-contact combination toxicity method. The results showed that the resistance of B. odoriphaga populations to chlorpyrifos and phoxim was very common in Shandong Province. The resistance ratio of Shenxian population was more than 30-fold to chlorpyrifos, while moderate resistance to betacypermethrin. Tai＇an population had low level resistance to beta-cypermethrin and lambda-cyhalothrin. However, all tested populations were relatively sensitive to imidacloprid and thiamethoxam.
