The essential oil (EO) of Thymus serpyllum and thymol were evaluated for their insecticidal activity against the housefly (Musca domestica) larvae and pupae. Contact toxicity and fumigation bioassays were used. Chemical composition analysis of T. serpyllum EO by gas chromatographic mass spectrometry (GC-MS) revealed that thymol (41.6%), p-cymene (21.9%), and γ-terpinene (19.2%) were the major components. For larval assays, the LC₅₀ value of T. serpyllum EO was 0.4 μl/cm² for contact toxicity and 20.9 μl/l for fumigation toxicity. For thymol, the contact toxicity LC₅₀ value was 0.035 μl/cm² and the fumigation LC₅₀ value was 2.0 μl/l. For the pupal assay, T. serpyllum EO had a percentage inhibition rate (PIR) value of 100% for both contact toxicity (1.0 μl/cm²) and fumigation toxicity assay (25 μl/l), whereas thymol had a PIR of 100% for contact toxicity (0.1 μl/cm²) and fumigation assay (5 μl/l). This study shows that T. serpyllum EO and thymol are toxic to housefly larvae and pupae and have the potential for use in the population control of this species.

评估了百里香和百里酚的精油 (EO)对家蝇 ( Muscadomestica ) 幼虫和蛹的杀虫活性。使用接触毒性和熏蒸生物测定。T 的化学成分分析。通过气相色谱质谱法 (GC-MS) 分析serpyllum EO 显示百里酚 (41.6%)、对伞花烃 (21.9%) 和 γ-萜品烯 (19.2%) 是主要成分。对于幼虫分析，T的 LC ₅₀值。serpyllum EO的接触毒性为 0.4 μl/cm ²，熏蒸毒性为 20.9 μl/l。对于百里酚，接触毒性 LC ₅₀值为 0.035 μl/cm ²熏蒸LC ₅₀值为2.0 μl/l。对于蛹化验，T。serpyllum EO 的接触毒性 (1.0 μl/cm ² ) 和熏蒸毒性测定 (25 μl/l) 的抑制百分比 (PIR) 值为 100% ，而百里酚的接触毒性 (0.1 μl) 的 PIR 为 100% /cm ² ) 和熏蒸试验 (5 μl/l)。这项研究表明，T . serpyllum EO 和百里酚对家蝇幼虫和蛹有毒，有可能用于控制该物种的种群。
