In order to find out the species of predatory mites and the dominant species of predatory mites in rubber trees in Hainan. We investigated the species by a five-point sampling method from 2015 to 2016, and evaluated the dominant species through dominance and frequency. The results showed that there were three families of predatory mites which were Phytoseiidae, Ascidae and Bdellidae, and Phytoseiidae as the most abundant species, constituting 85.05% of the total samples, followed by Ascidae, 14.71%, and Bdellidae the least abundant species, 0.24%. A comprehensive analysis of 13 species of predatory mites belonging to 4 genera in the family of Phytoseiidae was conducted through dominance and frequency. The results showed that the dominant species of the predatory mites in rubber trees in southern Hainan included Chanteius contiguus, Euseius vulgaris and Amblyseius hainanensis, with C. contiguus as the dominant species in rubber trees in southern Hainan, while Euseius ovalis as the dominant species in rubber trees in northern Hainan. The species and quantity of the dominant species in rubber trees in southern and northern Hainan differed greatly. This study would provide a theoretical basis for the further utilization of predatory mites in the biological control of Eotetranychus sexmaculatus and Eutetranychus orientalis in rubber trees.
