Some 42 million trees and 40% of total fruit production in Serbia make plum (Prunus domestica) the leading fruit grown in the country and Serbia the second top plum-producing country in Europe. Considering that this species is mass produced, as well as that two wild plums, cherry plum (Prunus cerasifera) and blackthorn (Prunus spinosa), are widespread on orchard margins throughout Serbia’s fruit-growing regions, in fences on roadsides and in shelterbelts, it can be assumed that cultivated and wild plum trees constitute the most significant pool of epiphyllic mites that are common on most fruit species. This study presents the data on spider mites (Tetranychidae) and predatory mites (Phytoseiidae) complexes hosted by plum, cherry plum and blackthorn fruit trees, which were collected in various regions in Serbia.

ACKNOWLEDGEMENTS
This research was partly funded by the Ministry of Education, Science and Technological Development of the Republic of Serbia [grant numbers TR31043 and TR20036].
A total of 62 samples were collected from 44 localities in Serbia between 1980 and 2014 (most samples were taken between 1991 and 2005). Mite identification was based on family keys for Phytoseiidae (Chant, 1959; Karg, 1993) and Tetranychidae (Prichard and Baker, 1955; Mitrofanov et al., 1987; Baker and Tuttle, 1994).
Materials and Methods
Species frequency was determined by the coefficient of constancy (C, %):C = Na/n × 100where Na = the number of samples where species A occurs, and n = total number of samples. The species were classified as accidental (C < 25%), accessory (C = 25-50%); constant (C = 50-75%) or euconstant (C = 75-100%) (Dajoz, 1977).Interspecific association was determined by the Jaccard index (Cj):Cj = a/(a + b + c)Where a = the number of samples where both species occur, b = the number of samples where only species A occurs, and c = the number of samples where only species B occurs. The significance of Cj values was tested by chi-square test: χ2 = N 3 (c – P)2/a × b (N –a)(N – b), where N = total number of samples, and P = a × b/N. Species A and B are significantly (*) associated if χ2 > 3.84; they are very significantly (**) associated if χ2 > 6.64 (Ludwig and Reynolds, 1988).
