Bioassays of Rosmarinus officinalis L. essential oil and blends of its major constituents were conducted using host-specific strains of the two-spotted spider mite, Tetranychus urticae Koch, on bean and tomato plants. Two constituents tested individually against a bean host strain and five constituents tested individually against a tomato host strain accounted for most of the toxicity of the natural oil. Other constituents were relatively inactive when tested individually. Toxicity of blends of selected constituents indicated a synergistic effect among the active and inactive constituents, with the presence of all constituents necessary to equal the toxicity of the natural oil.
利用二斑叶螨（Tetranychus urticae Koch）的寄主特异性菌株，在豆类和番茄植株上对迷迭香叶（Rosmarinus officinalis L.）精油及其主要成分混合物进行了生物测定。分别针对豆类寄主菌株测试的两种成分以及分别针对番茄寄主菌株测试的五种成分，构成了天然精油的大部分毒性。其他成分单独测试时相对无活性。所选成分混合物的毒性表明，活性成分和非活性成分之间存在协同效应，所有成分都存在才能达到与天然精油相同的毒性。
