二斑叶螨Tetranychus urticae Koch（阿卡里：叶螨科Tetranychidae）和烟粉虱Bemisia tabaci Germ.粉虱科（Aleyrodidae）是温室蔬菜和蔬菜上的两种重要害虫。目前的防治方法是重复施用化学药剂，造成环境污染和害虫种群的抗药性。荆芥和牛至Origanum vulgare L.（唇形科）对荨麻疹的成虫和/或成虫以及B的成虫进行毒性试验。烟粉虱在每个容量为4升的干燥器中，精油的施用量为2、4、6和8微升，对应于0.5、1、1.5和2微升/升空气。所有三种植物的精油蒸气在2 μ l/l空气剂量和暴露120 h时对两种害虫的死亡率最高。一般而言，随着精油剂量和接触时间的增加，观察到的死亡率较高。荨麻疹比B更耐受。在任何时候，任何剂量的精油都能杀死烟粉虱。这些数据可能表明，所有三种植物的精油都有潜力用于治疗荨麻疹和B。温室条件下的烟粉虱(c)2005 Elsevier B.

Tetranychus urticae Koch (Acari: Tetranychidae) and Bemisia tabaci Germ. (Homoptera: Aleyrodidae) are two economically important pests of greenhouse vegetables and ornamentals. The management is commonly done based on repetitive applications of chemicals, resulting in environmental pollution and resistance in pest population.In the present study, essential oil vapours from Micromeria fruticosa L., Nepeta racemosa L. and Origanum vulgare L. (Lamiaceae) were tested for toxicities against the nymphs and/or adults of T urticae and the adults of B. tabaci. Amounts of the essential oils applied were 2, 4, 6 and 8 mu l in each of the desiccators with 4 1 capacity, corresponding to 0.5, 1, 1.5 and 2 mu l/l air. The essential oil vapours of all three plant species caused the highest mortality in 2 mu l/l air doses and at 120 h of exposure in both of two pests' species. In general, higher mortality was observed as the doses of essential oils and exposure period increased. T urticae was more tolerant than B. tabaci at all doses of essential oils in all times. The data may suggest that essential oils of all three plants have potential to be used for management of T urticae and B. tabaci pests in greenhouse conditions. (c) 2005 Elsevier B.V.
