This work presents the biocidal (insecticidal, ixodicidal, nematicidal, and phytotoxic) effects and chemical compositions of three essential oils obtained from the industrial steam distillation (IEOs) of hyssop (Hyssopus officinalis L.), lavandin (Lavandula × intermedia or L. × hybrida var. Super), and cotton lavender (Santolina chamaecyparissus L.). Their chemical composition analyzed by gas chromatography coupled to mass spectrometry showed 1,8-cineole (53%) and β-pinene (16%) as the major components of H. officinalis, linalyl acetate (38%) and linalool (29%) of L. × intermedia; and 1,8-cineole (10%) and 8-methylene-3-oxatricyclo[5.2.0.0 ]nonane (8%) in S. chamaecyparissus. The biocidal tests showed that L. × intermedia IEO was the most active against the insect Spodoptera littoralis and toxic to the tick Hyalomma lusitanicum, IEO of H. officinalis was strongly active against S. littoralis, and finally, S. chamaecyparissus IEO was a strong antifeedant against the aphid Rhopalosiphum padi, toxic to H. lusitanicum and with moderate effects against Leptinotarsa decemlineata, S. littoralis, and Lolium perenne.
本研究展示了从牛膝草（Hyssopus officinalis L.）、杂薰衣草（Lavandula × intermedia或L. × hybrida var. Super）和棉薰衣草（Santolina chamaecyparissus L.）的工业水蒸气蒸馏所得三种精油的杀生物（杀虫、杀蜱、杀线虫和植物毒性）作用及化学成分。通过气相色谱 - 质谱联用分析其化学成分，结果表明，牛膝草精油的主要成分是1,8 - 桉叶素（53%）和β - 蒎烯（16%），杂薰衣草精油的主要成分是乙酸芳樟酯（38%）和芳樟醇（29%）；棉薰衣草精油的主要成分是1,8 - 桉叶素（10%）和8 - 亚甲基 - 3 - 氧杂三环[5.2.0.0]壬烷（8%）。杀生物测试表明，杂薰衣草精油对斜纹夜蛾的活性最强，对卢氏璃眼蜱有毒性；牛膝草精油对斜纹夜蛾有较强活性；最后，棉薰衣草精油对禾谷缢管蚜有很强的拒食作用，对卢氏璃眼蜱有毒性，对马铃薯甲虫、斜纹夜蛾和黑麦草有中等作用效果。
