A tool for integrated pest management is the use of essential oils (EOs) and plant extracts. In this study, EOs from Tagetes lucida , Lepechinia betonicifolia , Lippia alba , Cananga odorata , and Rosmarinus officinalis , species grown in Colombia, were analyzed by gas chromatography-mass spectrometry. These oils as well as several of their constituents were tested for repellent activity against Tribolium castaneum , using the area preference method. The main components (>10%) found in EOs were methylchavicol, limonene/α-pinene, carvone/limonene, benzyl acetate/linalool/benzyl benzoate, and α-pinene, for T. lucida, L. betonicifolia, L. alba, C. odorata, and R. officinalis, respectively. All EOs were repellent, followed a dose-response relationship, and had bioactivity similar to or better than that of commercial compound IR3535. EOs from C. odorata and L. alba were the most active. Compounds from EOs, such benzyl benzoate, β-myrcene, and carvone, showed good repellent properties. In short, EOs from plants cultivated in Colombia are sources of repellents against T. castaneum.
综合虫害管理的一个工具是使用精油（EOs）和植物提取物。在这项研究中，分析了在哥伦比亚种植的 Tagetes lucida、Lepechinia betonicifolia、Lippia alba、Cananga odorata 和 Rosmarinus officinalis 的精油，通过气相色谱-质谱法进行分析。这些油以及它们的一些成分，使用区域偏好法，被测试了对赤拟谷盗的驱避活性。在 T. lucida、L. betonicifolia、L. alba、C. odorata 和 R. officinalis 的精油中，发现的主要成分（>10%）分别为甲基丁香酚、柠檬烯/α-蒎烯、香芹酮/柠檬烯、乙酸苄酯/芳樟醇/苯甲酸苄酯和α-蒎烯。所有精油都具有驱避作用，遵循剂量反应关系，并且生物活性与商业化合物 IR3535 相似或更好。C. odorata 和 L. alba 的精油最具活性。精油中的化合物，如苯甲酸苄酯、β-月桂烯和香芹酮，表现出良好的驱避特性。总之，在哥伦比亚种植的植物的精油是赤拟谷盗的驱避剂来源。
