One of the most damaging pests of agricultural crops across the globe is the two-spotted spider mite, Tetranychus urticae Koch. A wide variety of arthropods and plant pathogens can be controlled by essential oils, which are secondary metabolites produced by plants. It is possible to enhance the stability as well as the anti-pest efficiency of plant essential oils by encapsulation. Water distillation was used to extract the essential oils from Eucalyptus globulus and Ferula assafoetida. The chitosan nanoparticles were used to load both essential oils into nanoformulations. Studies were conducted on T. urticae life table characteristics under experimental circumstances to determine the sublethal impacts of essential oils and their nanoformulations. Intrinsic growth rate (r) for population exposed to E. globulus, F. assafoetida essential oils, their nanoformulations and the control were 0.1, 0.069, 0.051, 0.018 and 0.21 per day, respectively. F. assafoetida and E. globulus nanoformulations resulted the lowest fecundity compared to the other treatments. According the result of the lethal and sublethal effects of purified essential oils and nanoformulations of F. assafoetida and E. globulus, they would be recommended for controlling the two-spotted spider mites, T. urticae.
全球农业作物最具破坏性的害虫之一是二斑叶螨，Tetranychus urticae Koch。植物次生代谢产物精油可以控制多种节肢动物和植物病原体。通过包封可以提高植物精油的稳定性和抗虫效率。用水蒸馏法从蓝桉和阿魏中提取精油。壳聚糖纳米粒子被用于将这两种精油载入纳米制剂中。在实验条件下研究了二斑叶螨生活史特征，以确定精油及其纳米制剂的亚致死作用。暴露于蓝桉、阿魏精油、其纳米制剂和对照中的种群的内禀增长率（r）分别为 0.1、0.069、0.051、0.018 和 0.21 天/天。与其他处理相比，阿魏和蓝桉纳米制剂的繁殖力最低。根据纯化精油和蓝桉、阿魏纳米制剂的致死和亚致死作用的结果，建议将它们用于防治二斑叶螨，Tetranychus urticae。
