Essential oils isolated from Cymbopogon citratus (DC) Stapf. and Eucalyptus citriodora Hook grown in Colombia were analysed by gas chromatography-mass spectrometry (GC-MS) and tested for repellent activity and contact toxicity against Tribolium castaneum (Herbst.) (Coleoptera: Tenebrionidae).
The main components of C. citratus oil were geranial (34.4%), neral (28.4%) and geraniol (11.5%), whereas those of E. citriodora were citronellal (40%), isopulegol (14.6%) and citronellol (13%). The mean repellent doses after 4 h exposure were 0.021 and 0.084 mL L(-1) for C. citratus and E. citriodora oils respectively-values lower than that observed for the commercial product IR3535 (0.686 mL L(-1)).
These studies showed the composition and repellent activity of essential oils of C. citratus and E. citriodora, suggesting that these are potential candidates as insect repellents.
从哥伦比亚种植的香茅（Cymbopogon citratus（DC）Stapf.）和柠檬桉（Eucalyptus citriodora Hook）中分离出的精油，通过气相色谱-质谱联用（GC-MS）进行了分析，并测试了它们对赤拟谷盗（Tribolium castaneum（Herbst.））（鞘翅目：拟步甲科）的驱避活性和接触毒性。
香茅油的主要成分是香叶醛（34.4%）、橙花醛（28.4%）和香叶醇（11.5%），而柠檬桉油的主要成分是柠檬醛（40%）、异松油醇（14.6%）和香茅醇（13%）。暴露 4 小时后的平均驱避剂量分别为 0.021 和 0.084 mL L（-1），低于商业产品 IR3535（0.686 mL L（-1））的观察值。
这些研究表明香茅和柠檬桉精油的组成和驱避活性，表明它们是潜在的驱虫剂候选物。
