Phytophagous mites are dangerous pests, causing economic losses to the world's crops. Nanotechnology is a promising field for pests and disease management, and enhancement of agricultural productivity. The aim of the study was to evaluation of the effectiveness of copper nanoparticles (CuNP) against all stages of eriophyid mite, the citrus rust mite, Phyllocoptruta oleivora (Ashmead) (Acari: Eriophyidae) and tetranychid mite, the citrus brown mite Eutetranychus orientalis (Klein) (Acari: Tetranychidae), and Tenuipalpid mite, the false spider mite, Brevipalpus obovatus Donnadieu (Acari: Tenuipalpidae). This includes its impacts on predacious mites, Amblyseius swirskii Athias-Henriot and Euseius scutalis (Athias-Henriot) (Acari: Phytoseiidae), on orange trees under field conditions. Five different concentrations of copper nanoparticles (40, 80, 160, 240, and 320 ppm), as well as the control (well water) were examined. The obtained results indicated that the mortality rate of both phytophagous and predacious mites was associated with an increase in the concentrations of copper nanoparticles. Copper nanoparticles were significantly effective in killing P. oleivora, E. orientalis and B. obovatus with minimal effects on A. swirskii and E. scutalis. The mortality percentage was 15.24, 20.32, 46.32, 78.97 and 86.37% for P. oleivora, 6.87, 9.86, 28.91, 56.30 and 77.52% for E. orientalis and 8.38, 23.50, 48.83, 68.80 and 84.08% for B. obovatus while the mortality percentage was 0.00, 0.56, 5.83, 9.91 and 15.19% for A. swirskii and 0.44, 3.96, 6.93, 8.63 and 21.39% for E. scutalis one week after exposure to 40, 80, 160, 240 and 320 ppm of copper nanoparticles, respectively. Moreover, the results showed that copper nanoparticles caused a reduction in the percentage of eggs hatching. The percentages of larvae hatching from eggs were 96.29, 80.00, 64.13, 45.66 and 32.17% for P. oleivora, 97.38, 83.28, 69.41, 48.01 and 35.29 for E. orientalis and 96.60, 76.92, 56.38, 40.55 and 33.28% for B. obovatus one week after exposure to copper nanoparticles at 40, 80, 160, 240 and 320 ppm respectively, compared with the control (well water). According to the results, the use of copper nanoparticles significant effect on reducing the population of phytophagous mites associated with orange trees, with low detrimental effects on predatory mites.
植食性螨类是危险的害虫，给全球农作物造成经济损失。纳米技术在病虫害管理和提高农业生产力方面是一个有前景的领域。本研究的目的是评估铜纳米颗粒（CuNP）对柑橘锈螨（Phyllocoptruta oleivora (Ashmead)，蜱螨亚纲：瘿螨科）、柑橘全爪螨（柑橘褐螨，Eutetranychus orientalis (Klein)，蜱螨亚纲：叶螨科）以及侧多食跗线螨（茶黄螨，Brevipalpus obovatus Donnadieu，蜱螨亚纲：跗线螨科）各发育阶段的防治效果。这包括在田间条件下其对捕食螨（斯氏钝绥螨（Amblyseius swirskii Athias-Henriot）和卵形真绥螨（Euseius scutalis (Athias-Henriot)，蜱螨亚纲：植绥螨科））以及橙子树的影响。研究检测了5种不同浓度的铜纳米颗粒（40、80、160、240和320 ppm）以及对照（井水）。所得结果表明，植食性螨类和捕食螨类的死亡率均与铜纳米颗粒浓度的增加有关。铜纳米颗粒对杀灭柑橘锈螨、柑橘全爪螨和侧多食跗线螨具有显著效果，而对斯氏钝绥螨和卵形真绥螨的影响最小。在分别暴露于40、80、160、240和320 ppm铜纳米颗粒一周后，柑橘锈螨的死亡率分别为15.24%、20.32%、46.32%、78.97%和86.37%；柑橘全爪螨的死亡率分别为6.87%、9.86%、28.91%、56.30%和77.52%；侧多食跗线螨的死亡率分别为8.38%、23.50%、48.83%、68.80%和84.08%；而斯氏钝绥螨的死亡率分别为0.00%、0.56%、5.83%、9.91%和15.19%，卵形真绥螨的死亡率分别为0.44%、3.96%、6.93%、8.63%和21.39%。此外，结果表明铜纳米颗粒会降低卵的孵化率。与对照（井水）相比，在分别暴露于40、80、160、240和320 ppm铜纳米颗粒一周后，柑橘锈螨卵孵化出幼虫的比例分别为96.29%、80.00%、64.13%、45.66%和32.17%；柑橘全爪螨分别为97.38%、83.28%、69.41%、48.01%和35.29%；侧多食跗线螨分别为96.60%、76.92%、56.38%、40.55%和33.28%。根据结果，使用铜纳米颗粒对减少与橙子树相关的植食性螨类种群数量有显著效果，且对捕食螨类的有害影响较低。
