The results of a research conducted from 1980 to 2016 of leaf mites of stone fruit trees (Prunus spp.) in Serbia are presented. The species complex of 9 spider mite species and 16 phytoseiid species was recognized on 10 Prunus species. A total of 17 mite species were found on cherry plum (Prunus cerasifera Ehrh.) and blackthorn (Prunus spinosa L.), 16 species were found on sweet cherry (Prunus avium L.), and 13 species were found on plum (Prunus domestica L.). The highest coefficient of constancy among the spider mites was found for Bryobia rubrioculus (Scheuten) (27.9%), and among the phytoseiids for Euseius finlandicus (Oudemans) (58.7%). Very significant positive values of the association index were found for the pairs: Typhlodromus (Typhlodromus) pyri Scheuten–Bryobia angustisetis Jakobashvili, Neoseiulella aceri (Collyer)–Panonychus ulmi (Koch), N. aceri–Bryobia sp., Phytoseius corniger Wainstein–T.(T.) pyri, N. aceri–P. echinus, P. macropilis –Paraseiulus soleiger (Ribaga). Significant positive values were noted for the the pairs P. corniger–Bryobia sp., P. echinus–Bryobia sp., and K. aberrans–P. echinus. Very significant negative index values were detected for the pairs E. finlandicus–K. aberrans and E. finlandicus–P. macropilis, and a significant negative index of association for the pair A. andersoni–A. viennensis.
