“…This increased contact could lead to a higher uptake of nanoparticles and subsequent toxicity [22]. The results of this study are consistent with many previous studies on several species of mites such as T. urticae mite [23], tomato russet mite Aculops lycopersici and two-spotted mite T. urticae [24] date palm mite (O.afrasiaticus (McGregor)) [10].…”

“…Nanosilver has been extensively studied for its miticidal activity against various pests. It has shown promising results in controlling the moving stages and eggs of phytophagous mites, including O. afrasiaticus [10]. Additionally, nanosilver has demonstrated selectivity towards pests while minimizing harm to non-target predatory mites, making it a potential environmentally friendly solution for date palm pest management [11].…”

Date palm mite Oligonychus afrasiaticus (McGregor) (Acari: Tetranychidae) infestations pose a significant threat to date palm plantations, leading to reduced crop yield and economic losses. Nanoparticle-based strategies have emerged as a promising approach for controlling mite populations due to their unique physicochemical properties and environmentally friendly nature. In this study, we investigated the impact of three different nanoparticle types, namely silver, silica, and sulphur, on the mortality rate of date palm mites at different life stages (larvae, nymphs, and adults). The experiments were conducted at various concentrations and time intervals to assess the efficacy of the treatments. The results revealed significant variations in the effectiveness of the nanoparticle types, with nanosulphur demonstrating the highest mortality rate (45.576%) followed by silica (38.587%) and silver nanoparticles (34.957%). Furthermore, the results indicated that adult mites were more susceptible to nanoparticle-induced mortality compared to larvae and nymphs. The concentration-dependent response showed that higher nanoparticle concentrations led to greater mite mortality, with the highest concentration (500 ppm) resulting in an impressive mortality rate of 55.163%. Time-dependent studies demonstrated a progressive increase in mortality rates over 48 hours, reaching 46.017% at the endpoint. These findings provide valuable insights into the differential susceptibility of date palm mite life stages to nanoparticle treatments and underscore the importance of considering both nanoparticle type and concentration for effective control of date palm mites. This knowledge contributes to the development of targeted nanoparticle-based strategies for mitigating date palm mite infestations and preserving the productivity of date palm plantations. This study contributes valuable insights into the potential use of nanoparticle-based treatments for managing O. afrasiaticus infestations in date palm trees.

Bell Pepper plants are widely grown and utilized all over the world. A number of phytophagous mites are associated with this plant and the control over these pests has been a challenge to growers due to its development of resistance to synthetic chemicals and short reproduction cycle. The agriculture sector is currently embracing nanotechnology as a target-specific, relatively safe, and effective alternative to traditional pest management tools. The main goal of undertaking the current study was to evaluate the effectiveness of different doses (200, 400, 600, 1000, 1250 and 1500 ppm) of zinc oxide nanoparticles (ZnONPs) at all growth stages of the mites; Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae) and the two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae). Simultaneous impacts on predatory mites, Neoseiulus cucumeris (Oudemans) and Euseius scutalis (Athias-Henriot) (Acari: Phytoseiidae) was also observed. All trails were carried out under field and laboratory conditions. The obtained results have shown that an increase in zinc oxide nanoparticle concentrations was related to a higher mortality rate of both phytophagous mites. While negligible impact on N. cucumeris and E. scutalis was observed. zinc oxide nanoparticles demonstrated great efficacy in eliminating P. latus and T. urticae. The percentages of deaths were 25.59, 42.36, 56.43, 72.02, 85.47 and 97.07% for P. latus and 22.61, 39.79, 52.66, 69.35, 82.22 and 95.24% for T. urticae, while the mortality percentage was 1.78, 3.60, 4.44, 15.30, 16.67 and 19.59% for N. cucumeris and 3.68, 5.33, 7.21, 17.92 and 20.26% for E. scutalis three days after exposure to 200, 400, 600, 1000, 1250 and 1500 ppm of zinc oxide nanoparticles, respectively. Additionally, the findings showed that the use of zinc oxide nanoparticles reduced the percentage of egg hatching. The percentages of eggs that hatch into larvae were 79.33, 69.51, 62.66, 46.54, 43.62 and 39.08% for P. latus and 83.17, 71.60, 67.26, 48.94, 46.95 and 38.26 for T. urticae three days after exposure to 200, 400, 600, 1000, 1250 and 1500 ppm of zinc oxide nanoparticles respectively, compared with the control (well water). Lethal concentration; LC50 (µg/ml) at confidence level 95 (CL95) was found to be 556.4 and 611.8 for P. latus and T. urticae and 2304.6 and 2259.7 for N. cucumeris and E. scutalis. Similarly, LC95 (µg/ml) was found to be 1325.9 and 1404.9 for P. latus and T. urticae and 33671.2 and 3773.8 for N. cucumeris and E. scutalis. The investigation proved that zinc oxide nanoparticles are a useful tool for controlling P. latus and T. urticae.
