Among the vectorial insect pests, the domestic house fly (Musca domestica L., Diptera: Muscidae) is a ubiquitous livestock pest with the ability to develop resistance and adapt to diverse climates. Successful management of the house fly in various locations requires information about its resistance development and life table features. The status of insect growth regulators resistance and life table features on the basis of age, stage, and two sexes of the house fly from five different geographical locations of Riyadh, Saudi Arabia: Dirab, Al-Masanie, Al-Washlah, Al-Uraija and Al-Muzahmiya were therefore investigated. The range of resistance levels were 3.77-8.03-fold for methoxyfenozide, 5.50-29.75 for pyriproxyfen, 0.59-2.91-fold for cyromazine, 9.33-28.67-fold for diflubenzuron, and 1.63-8.25-fold for triflumuron in five populations of house fly compared with the susceptible strain. Analysis of life history parameters-such as survival rate, larval duration, pupal duration, pre-female duration, pre-male duration, adult and total pre-oviposition periods, longevity of male, oviposition period, female ratio, and fecundity female-1-revealed significant variations among the field populations. Additionally, demographic features-including the generation time, the finite and intrinsic rates of increase, doubling time, and net reproductive rate-varied significantly among the field populations. These results will be helpful in planning the management of the house fly in geographically isolated dairies in Saudi Arabia.
在媒介昆虫中，家蝇（Musca domestica L.，双翅目：蝇科）是一种无处不在的家畜害虫，具有抗药性和适应不同气候的能力。要在不同地点成功管理家蝇，就需要了解其抗药性发展和生命表特征方面的信息。本研究调查了沙特阿拉伯利雅得五个不同地理位置（Dirab、Al-Masanie、Al-Washlah、Al-Uraija 和 Al-Muzahmiya）的家蝇基于年龄、阶段和两性的昆虫生长调节剂抗性和生命表特征的状况。家蝇对甲氧虫酰肼的抗性水平范围为 3.77-8.03 倍，对吡丙醚的抗性水平范围为 5.50-29.75 倍，对环丙虫酰胺的抗性水平范围为 0.59-2.91 倍，对除虫脲的抗性水平范围为 9.33-28.67 倍，对氟铃脲的抗性水平范围为 1.63-8.25 倍，与敏感品系相比，这五个家蝇种群均表现出不同程度的抗药性。对生命史参数（如存活率、幼虫期、蛹期、雌前期、雄前期、总预产卵期、雄成虫寿命、产卵期、雌雄性比和雌成虫 1 代产卵量）的分析表明，田间种群之间存在显著差异。此外，种群动态特征（包括世代时间、有限和内禀增长率、倍增时间和净生殖率）在田间种群之间也存在显著差异。这些结果将有助于规划沙特阿拉伯地理隔离奶牛场的家蝇管理。
