Suitability of the Citrus Brown Mite,Eutetranychus orientalis (Acari, Tetranychidae) as prey for nine species of phytoseiid mites

  • F. Momen
  • M. El-Borolossy


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