This study was conducted to determine beneficial mite species of Hevsel Gardens in Diyarbakir province in 2018-2019. These historical gardens, which have been cultivated continuously for thousands of years, are listed on UNESCO World Heritage List. Survey studies were carried out periodically every 15 days from April to November with the random sampling method. In the study, samples were taken from 66 plants species consisting of fruit trees, vegetables, and weeds. As a result of the study, 15 predator mite species from families Tydeidae, Cheyletidae, Stigmaeidae, Triophtyidae, Raphignathidae, Iolinidae, and Phytoseiidae were identified on 33 plants species. Among these families, 7 from Phytoseiidae, 3 from Iolinidae, and one species from other families were determined. Phytoseius finitimus (Ribaga, 1904) (Mesostigmata: Phytoseiidae) was the dominant species with 37.5%. The highest number of mite species were found on Rubus sp. with 7 species. In the study, more beneficial mites were found in regions where agricultural activity is less. Predator mites were mostly found on fruit trees, and less frequently on vegetables and fragrant plants. Poplar and mulberry trees have a high population in Hevsel Gardens. Although many samples were taken from these two plants during the surveys, only P. finitimus was found. With this two-year study, it has been revealed that Hevsel Gardens, which are important for the world, are rich in beneficial mites. Important predator species used in the world for biological control against harmful mites and insects have been identified. With study, beneficial species that create new records for the region were determined.
