Thymus quinquecostatus Celak. of the Lamiaceae family has a long history of dual use of medicine and food with high economic value, and has been proved to have good antioxidative, antimicrobial, and antidiabetic activities. Essential oil (EO) extracted from the aerial part of T. quinquecostatus was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC/MS) and GC. Totally 45 compounds were identified accounting for 98.5 % of the EO. The major constituents of the EO were linalool (52.003 %), borneol (10.911 %) and anethole (5.325 %). Fumigant, contact and repellent activity of T. quinquecostatus essential oil (EO) against Tribolium castaneum (Coleoptera: Tenebrionidae), Lasioderma Serricorne (Coleoptera: Anobiidae), Liposcelis bostrychophila (Psocoptera: Liposcelididae) were evaluated in this work. T. quinquecostatus EO and three major constituents showed varying degrees of insecticidal and repellent activities to three stored-product insects. Anethole stated the best fumigant and contact activity than others did to all three insect species. EO and compounds showed general repellent activity against three target insects. This work suggests that the EO of T. quinquecostatus has promising potential to be developed into botanical pesticides and repellents controlling pest damage in warehouses and grain stores.

Thymus quinquecostus Celak 的杀虫和驱虫活性。精油和主要成分对抗三种贮藏昆虫

百里香 quinquecostus Celak。唇形科植物的药食两用历史悠久，具有较高的经济价值，已被证明具有良好的抗氧化、抗菌和抗糖尿病活性。从T. quinquecostus地上部分提取的精油 (EO)通过水蒸馏获得，并通过气相色谱-质谱 (GC/MS) 和 GC 进行分析。共鉴定出 45 种化合物，占 EO 的 98.5%。EO 的主要成分是芳樟醇 (52.003 %)、冰片 (10.911 %) 和茴香脑 (5.325 %)。T. quinquecostus精油 (EO) 对Tribolium castaneum (Coleoptera: Tenebrionidae), Lasioderma Serricorne 的熏蒸、接触和驱避活性（鞘翅目：Anobiidae），Liposcelis bostrychophila（Psocoptera：Liposcelididae）在这项工作中进行了评估。T. quinquecostus EO 和三种主要成分对三种贮藏昆虫表现出不同程度的杀虫和驱避活性。茴香脑对所有三种昆虫的熏蒸和接触活性均优于其他产品。EO和补偿ounds表现一般驱除活性对三名目标昆虫。这项工作表明，T. quinquecostus的 EO具有开发成植物杀虫剂和驱虫剂的潜力，可控制仓库和粮库中的害虫危害。
