| description | Predatory mites are biological control agents used in many countries against various vegetable pests, particularly spider mites. Despite the significant presence of predatory mites in the Tibetan plateau, there is limited research on their potential against spider mites in the area. This study investigated the fitness parameters and performance against TSSM of four predatory, including <i>Amblyseius swirskii</i> (Athias-Henriot) and three species from the genus <i>Neoseiulus</i> (<i>Neoseiulus californicus</i> (McGregor), <i>Neoseiulus barkeri</i> (Hughes), and <i>Neoseiulus cucumeris</i> (Oudemans)), originally collected from fields in the Tibetan Plateau. Compared to the other three predatory species, <i>A. swirskii</i> exhibited the highest fecundity (11.60 ± 0.34) and the highest pre-adult survival rate (83.33 ± 3.33%). Since their juvenile survival rate (SR) was extremely low (13.33% ± 5.77%), most <i>N. barkeri</i> nymphs died before emergence. Compared to the other three predatory mites, <i>A. swirskii</i> showed the highest predation capacity against adult TSSMs at 15 d post-release (14.28 ± 2.24). Based on the results, <i>A. swirskii</i> was the most effective, and <i>N. barkeri</i> was the least effective in controlling two-spotted mites in the Tibetan Plateau among the four species tested in this study. Collectively, these findings imply notable advantages in employing <i>A. swirskii</i> for controlling two-spotted mites in the Tibetan Plateau. This study informs the development of a feasible biological control method based on suitable predatory mite species to manage TSSMs in the Tibetan Plateau. |
