Since there is an urgent need to control <em>O. mangiferus</em>, searching for native phytoseiids that can prey on <em>O. mangiferus</em> may provide promising results in the biological control of this mite pest. In this study, biological and life table parameters of the predatory mites <em>Cydnoseius negevi</em>, <em>Neoseiulus barkeri</em>, <em>Paraseiulus talbii</em>, and <em>Typhlodromus athiasae</em> were determined when fed on <em>O. mangiferus</em> under laboratory conditions. <em>Cydnoseius negevi</em>, <em>N. barkeri</em>, and <em>T. athiasae</em> were successfully fed and developed on <em>O. mangiferus</em>, while <em>P. talbii</em> failed to develop on <em>O. mangiferus</em>. The pre-adult duration did not differ significantly among the three phytoseiids. The longest female longevity was 40.28 days for <em>N. barkeri</em>, while the shortest was 26.04 days for <em>C. negevi</em>. The lowest daily fecundity was observed in <em>N. barkeri</em> females, whereas the highest was oviposited by <em>C. negevi</em> and <em>T. athiasae</em>. Statistically, <em>Typhlodromus athiasae</em> had the maximum intrinsic rate of increase (<em>r</em>) and finite rate of increase (<em>λ</em>), followed by <em>N. barkeri</em> and <em>C. negevi</em>. The shortest mean generation time (<em>T</em>) and the lowest net reproductive rate (<em>R</em>₀) were reported for <em>C. negevi</em>. In conclusion, <em>C. negevi</em>, <em>N. barkeri</em>, and <em>T. athiasae</em> successfully fed, developed and sustained oviposition on <em>O. mangiferus</em>. Therefore, they could be considered as important biological control agents of <em>O. mangiferus.</em> https://www.persianacarology.org/article_238534_632a808c71819f9d7ee5577a7d18d790.pdf
