The house fly, L., is a pest of great medical and agricultural importance, serving as a vector for various diseases and undermining the quality of agricultural products. Traditionally, synthetic insecticides have been the primary means of control; however, their efficacy has declined over time, and they are now less preferred due to their safety and environmental concerns. This study evaluated the insecticidal and repellent properties of essential oils from , and against . All EOs exhibited insecticidal activity: eucalyptus achieved 100% fumigant mortality at 34 µL L air and showed the lowest LC (18.1 µL L air), while fennel and sage required 50 µL L air. In contrast, fennel showed the highest contact toxicity (100% mortality at 150 µL L). Repellency exceeded 87% for all EOs, with sage being the most repellent at the lowest concentration tested (94% at 5 µL L). These results highlight the potential use of essential oils and their constituents as environmentally friendly alternatives for the control of . However, further field validation and studies on individual components and their synergistic combinations are needed to understand their efficacy and fully optimize their use.
家蝇，双翅目蝇科，是一种具有重大医学和农业意义的害虫，它作为多种疾病的传播媒介，会降低农产品质量。传统上，合成杀虫剂一直是主要的防治手段；然而，随着时间的推移，它们的功效有所下降，并且由于安全和环境问题，现在不太受青睐。本研究评估了来自桉属、茴香属和鼠尾草属植物的精油对家蝇的杀虫和驱避特性。所有精油均表现出杀虫活性：桉属植物精油在34 μL/L空气中达到100%熏蒸死亡率，且表现出最低的致死浓度（18.1 μL/L空气），而茴香属和鼠尾草属植物精油则需要50 μL/L空气。相比之下，茴香属植物精油表现出最高的接触毒性（在150 μL/L时死亡率为100%）。所有精油的驱避率均超过87%，鼠尾草属植物精油在测试的最低浓度（5 μL/L时为94%）下是最具驱避性的。这些结果突出了精油及其成分作为控制家蝇的环境友好型替代品的潜在用途。然而，需要进一步的田间验证以及对单个成分及其协同组合的研究，以了解它们的功效并充分优化其使用。
