Ecology and distribution ofof Euseius finlandicus (Parasitiformes, Phytoseiidae) in garden phytocenoses of Transcarpathian region

Abstract

The article describes the ecology and distribution of the species Eu. finlandicus Oudemans, 1915 (Parasitiformes, Phytoseiidae) in the garden phytocenoses of Transcarpathian region. In Ukraine, such studies were conducted for the Forest-Steppe zone. The mites were collected during the period of 2012–2014. In total, nine settlements of Transcarpathian region were studied. On the researched territory Eu. finlandicus inhabits at least 26 species of plants. For the first time, the status of the species Eu. finlandicus is determined in acaro-complexes of the family Phytoseiidae in garden phytocenoses of Transcarpathian region. The indices of occurrence and dominance for this species are calculated. Species of plants on which Eu. finlandicus is present in garden phytocenoses of Transcarpathian region are described. Results of the study suggest that Eu. finlandicus is a common species in garden phytocenoses of Transcarpathian region. The results can become the theoretical basis for development of schemes aimed at enhancing the protective function of useful mites in phytocenoses of the Uzhgorod district.
