This study was conducted to determine the susceptibility and resistance of some house fly strains of Musca domestica L. to the insect growth regulator insecticides triflumuron and pyriproxyfen in some locations in Riyadh city. Field-collected strains of M. domestica L. from five sites in Riyadh city that represented five slaughterhouse sites where flies spread significantly were tested against triflumuron and pyriproxyfen. Triflumuron LC50 values for the five collected strains ranged from 2.6 to 5.5 ppm, and the resistance factors (RFs) ranged from 13-fold to 27-fold that of the susceptible laboratory strain. Pyriproxyfen LC50 values for the field strains ranged from 0.9 to 1.8 ppm with RFs of 3-fold to 5-fold. These results indicate that pyriproxyfen is an effective insecticide to control house flies and should be used in rotation with other insecticides in the control programs applied by Riyadh municipality.
本研究旨在确定利雅得市五个地点采集的家蝇（Musca domestica L.）品系对昆虫生长调节剂杀虫剂三氟脲和吡丙醚的敏感性和抗药性。从利雅得市五个屠宰场（苍蝇传播严重的五个地点）采集的家蝇田间品系，对三氟脲和吡丙醚进行了测试。五个采集品系的三氟脲 LC50 值范围为 2.6 至 5.5 ppm，抗药性因子（RF）范围为敏感实验室品系的 13 至 27 倍。田间菌株的吡丙醚 LC50 值范围为 0.9 至 1.8 ppm，RF 值为 3 至 5 倍。这些结果表明，吡丙醚是一种有效的控制家蝇的杀虫剂，应与利雅得市实施的控制计划中的其他杀虫剂轮换使用。
