20 mite species of 10 genera of Phytoseiidae were found on the plants in urban environment, namely Amblyseius andersoni Chant, 1957; Amblyseius rademacheri Dosse, 1958; Neosiulus herbarius Wainstein, 1960; Neoseiulus reductus Wainstein, 1962; Euseius finlandicus, Oudemans, 1915; Kampimodromys aberrans Ouderman, 1930; Dubininellus echinus Wainstein et Arutunjan, 1970; Dubininellus juvenis Wainstein et Arutunjan, 1970; Typhlodromus cotoneastri Wainstein, 1961; Typhlodromus laurae Arutunjan, 1974; Typhloctonus aceri Collyer, 1957; Typhloctonus tiliarum Oudemans, 1930; Paraseiulus incognitus Wainstein et Arutunjan, 1967; Paraseiulus soleiger Ribaga, 1902; Amblydromella (s.str.) caudiglans Scheuten,1959; Amblydromella (s.str.) pirianykae Wainstein, 1972; Amblydromella (s.str.) rhenana Oudemans, 1905; Amblydromella clavata Wainstein, 1972; Amblydromella (Aphanoseius) verrucosa Wainstein, 1972; Galendromus longipilus Nesbitt, 1951. The peculiarities of their distribution in plant associations of Kyiv city, Uman city, Vasylkiv town, and Brovary town (Ukraine) were determined together with some spatial characteristics (population, area, urbanization degree, etc.). Common and rare species (that occurred only in one area of study) were ascertained; their biotopic relation with host plant species was estimated. Species composition of mites on the grass and tree-and-shrub plants in all the territories of associations was researched separately. Comparative characteristic of species composition of phytoseiidae mites on the plants that grew along the city streets and green plantations of the parks was made. We discovered definite patterns in mites distribution. Dominant species, subdominant, subdominant of first order, and minor members of species communities were revealed while analyzing the structure of predacious phytoseiidae mites. E. finlandicus species is dominant in all research territory: Kyiv (Di=51,63%), Uman (Di=60,32%), Vasylkiv (Di=15,65%), Brovary (Di=33,90%). K. aberrans (Di=15,52%) and finlandicus were the dominants in Vasylkiv town. K. aberrans (Di=2,35%) and T. aceri (Di=1,30%) were the subdominants in phytoseiidae mite communities. We also registered some predacious phytoseiidae mites - A. caudiglans and A. rhenana species which had the features of stenoecic species, while they considered to be the euryoecic species. Among euryoecic species there was a group of species with positive biotopic affinity to all the studied plants – A. rademacheri, N. reductus, N. herbarius, D. juvenis, T. сotoneastri, T. laura, A. pirianykae, A. clavata, G. longipilus, and species that had negative indexes to some plant species – A. andersoni, E. finlandicus, K. aberrans, D. echinus, T. aceri, T. tiliarum, P. incognitus, P. soleiger. |
