Mite species belongs to Tetraychychidae (3); Tenupalpidae (2), Stigmaeidae (1), Tydeiidae (2), (Acari: Prostigmata); Phytoseiidae (10) (Acari: Mesostigmata) and Acaridae (1) (Astigmata) were identified on woody ornamental plants and shrubs in Erzurum (Eastern part of Turkey). The samples were collected from Erzurum (Centrum, Pasinler, Köprüköy, Horasan, Aziziye-Ilıca, Aşkale, Tortum, Uzundere and Çat districts) with a weekly interval between April to October during 2015 and 2016. Five species were phytophagous mites (belong to Tenuipalpidae and Tetranychidae), while the others are considered as predators or feed on microorganisms, neutral in their habitats. Nineteen mite species representing in three orders: Amblyseius andersoni (Chant), Kampimodromus aberrans (Oudemans), Euseius finlandicus (Oudemans), Typlodromus cotoneastri (Wainstein), Neoseiulus astutus (Beglyarov), Phytoseius finitimus Ribaga, Typhlodromus (Anthoseius) kerkirae Swirski and Ragusa, Typhlodromus (Anthoseius) recki (Wainstein), Paraseiulus soleiger (Ribaga), Neoseiulella tiliarum (Oudemans), Zetzellia mali (Ewing), Tydeus kochi Oudemans, Tydeus californicus (Banks), Tetranychus urticae Koch, Bryobia rubrioculus (Scheuten), Bryobia praetiosa Koch, Cenopalpus pulcher (Canestini & Fanzago) Brevipalpus californicus (Banks), Tyrophagus putrescentiae. These results showed that Erzurum has rich biodiversity especially concerning predatory mite fauna. T. urticae (Schrank), was the most abundant and common phytophagous species (53.11%) while some other species were represented only one specimen (Neoseiulus astutus (Beglyarov) (Phytoseiidae). Most preferred hosts plants were Philadelphus coronarius L. (Hydrangeaceae) (8), Malus coronaria L. (Rosaceae) (7) and Rosa canina L. (Rosaceae) (6) while Syringa vulgaris L. (Oleaceae), Salix sp. (Salicaceae) and Rosa pisiformis (Christ) (Rosaceae) were populated by only (2) and (1) mite species respectively.
