Nine phytoseiid species were tested to evaluate their potential as predators of Eutetranychus orientalis (Klein). Typhlodromus athiasae Porath and Swirski, Amblyseius barkeri (Hughes) and A. olivi Nasr and Abou-Awad had a shorter developmental period than T. transvaalensis (Nesbitt). T. athiasae and A. barkeri showed the highest oviposition rates. A. olivi showed a low rate of oviposition although T. transvaalensis has not able to lay any eggs. Immatures survival of T. talbii Athias-Henriot, T. balanites El-Badry, Amblyseius badryi Yousef and El-Borolossy, A. cabonus (Schicha) and A. lindquisti Schuster and Pritchard were very low on E. orientalis and all failed to develop to adulthood.
