Structure of species complexes of predatory phytoseiid mites (Phytoseiidae) and their distribution were studied in plant associations of Uman’ town (Cherkasy Region, Ukraine). Twelve species of seven genera of phytoseiid mites were revealed. It was observed centripetal reduction of the species diversity in the phytoseiid complexes from the outlying districts to the center of the town.

20 species of 10 genera of mites of this family Phytoseiidae were found while studying a species composition on the plants of urban environment Amblyseius andersoni Chant, 1957; Amblyseius rademacheri Dosse, 1958 Nesbitt, 1951. The peculiarities of their spreading in plant associations of Kyiv city, Uman city, Vasylkiv town, Brovary town (Ukraine) which differed from each other by various characteristics (population, area, urbanization degree, etc.) were determined. Total 68 species of plants were examined in the territory of Kyiv city where there were 40 species of trees and shrubs (including 2 types of conifers) and 28 species of herbaceous plants; 16 species of 10 genera of predacious phytoseiid mites were found. 14 species of 8 genera of mites were registered on 25 plant species in the territory of Brovary town (16 species of tree-and-shrub and 9 species of herbaceous plants) in the result of processing of collected materials. 10 species of 7 genera were identified while studying the current state of species diversity of predacious mites of Phytoseiidae family on 26 species of trees and shrubs of green urban plantations within Vasylkiv town. 12 species of 7 genera of Phytoseiidae mites were identified in the result of study of urban plantations in Uman city. Common species at studied areas were the following seven species: A. andersoni, A. rademacheri, E. finlandicus, K. aberrans, T. laurae, T. aceri, T. tiliarum. During the researches the domination index (Di). It was found that spreading of mites was different. Dominant species, subdominant species, subdominant of first order and minor members of species complexes were revealed while analysed the species structure of predacious phytoseiidae mites. E. finlandicus was the dominant in all research plots: Kyiv (Di = 51.63 %), Uman (Di = 60.32 %), Vasylkiv (Di = 15.65 %), Brovary (Di = 33.90 %). K. aberrans (Di = 15.52 %) and E. finlandicus was determined as dominant species n Vasylkiv town. K. aberrans (Di = 2.35 %) and T. aceri (Di = 1.30 %) had the status of subdominant species in research areas.We also have been studied the mite species diversity on the grass and shrubs. We studied the mites on the 93 species of plants where 55 were trees and shrubs (58.9 %) and 38 species were the herbaceous plants (41.1 %).Key words: phytoseiid mites; Phytoseiidae; Kyiv city; Uman city; Vasylkiv town; Brovary town; Ukraine Особливості структури комплексів фітосеїдних кліщів в рослинних асоціаціях міст С.Л.

This article deals with the results of study of species content and basic peculiarities of beaked mites-Phytoseiidae in plant associations of one of the regional centers of Ukraine. The species composition and distribution of mites-Phytoseiidae (Parasitiformes, Phytoseiidae) in plantations of Brovary town of Kyiv region were determined. Fourteen species of 8 genera of phytoseiid mites were found. Index of their existing and relative biotope connection of each registered species to vegetation types and plant species were computed. The study was conducted according to the results of material treatment on the territory of the mentioned city from 25 species of plants (16 species of hardy-shrub and 9 of herbaceous vegetations). The studies of distribution of plant-living mites-Phytoseiidae were conducted separately for hardy-shrub and herbaceous plants). The collection of faunistic material was executed during the vegetation of periods of 2011 and 2013. Within the city the collection of the material was conducted with hardy-shrub plants and herbaceous type of vegetation along the streets, in parks and squares of Brovary city of Kyiv region, district center, one of the satellite-cities of Kiev, the capital of Ukraine. The study of species complexes characteristics of mites was conducted with usage of data calculated on the basis of frequency index (Is), degree of relative habitat confinedness (F) (Pesenko, 1982) and domination index Paliy-Kovnatski (Di) (Shitikov, 2003). Only on one species of plant (F=1) 6 species of mites-Phytoseiidae were found – T.сotoneastri on blue spruce, T. laurae – on common spruce, T. aceri – on ash-leaved maple, P. incognitus – on dog-rose, P. soleiger – on mulberry-tree, A. caudiglans – on sea-buckthorn. These species can be related to stenoecic. The mentioned species are stenotopic only in relation to the sample of plants from the plant associations of Brovary, as in other regions these species of mites can populate the other species of plants. The rest 8 species, being registered on two or more types of plants, are related to euryoecic. Among them there is a group of 6 species with “positive tendencies to population of plants”, owning the indicators of habitat confinedness 0<F<1: A. andersoni (0,92–0,96), A. rademacheri (0,85–0,96), N. herbarius (0,92–0,96), T. tiliarum (0,66–0,77), A. pirianykae (0,73–0,99), A. clavata (0,82–0,98). The rest species, E. finlandicus и K. aberrans, have the expanded range of indicators in relation to habitat confinedness (-0,71<F<0,55 и -0,16<F<0,88), that specifies on their ability to populate the big quality of species. E. finlandicus has the negative indicator of relative habitat confinedness in relation to the plants of herbaceous morphotype that serves confirmation of the ecological peculiarity of the species detected earlier. The data of relative habitat confinedness of mites to certain species of plants shows availability of stenoecic (T.сotoneastri, T. laurae, T. aceri, P. incognitus, P. soleiger, A. caudiglans) and euryoecic species (A. andersoni, A. rademacheri, N. herbarius, E. finlandicus, K. aberrans, T. tiliarum, A. pirianykae, A. clavata).

We founded that E. finlandicus and K. aberrans formed the nucleus of Phytoseiidae community on the plants of urbanized environment in the result of study of 93 plant species (55 species of tree-and-shrub (58.9%) and 38 species of herbaceous plants (41.1%). Our research was carried out in plantations along the main and secondary municipal highways, near residential area and industrial buildings, on private plots of the private building area, in city parks and squares of Kyiv, Uman, Brovary, and Vasylkiv (Ukraine). The peculiarities of their distribution among urban plant associations, which differ from each other by different characteristics (population, area, degree of urbanization) were determined. Both species - E. finlandicus and K. aberrans have a rather extended range of indicators of relative biotope contiguity (-0.91<Fij<0.43 and -0.93Fij<0.96) that indicated their property to inhabit large number of plants. The indicator of K. aberrans occurrence, which was the highest in the city with the smallest degree of urbanization (Vasylkiv), decreased in the city with the maximum possible degree of urbanization (Kyiv). This indicator of E. finlandicus on the contrary increased along the gradient from a smaller city to the metropolitan city. K. aberrans inhabit a large number of plant species (33 species), while preferred plants from Rosacea family. E. finlandicus dominated by number of urban plant species it inhabited (75 species, 79.78%), absolute number of individuals in collected samples of predatory mites (504), occurrences index (Is = 74.49%), and by index of Palii-Kovnatsi (Di = 51.42%). The dominance of E. finlandicus species was registered in both groups of plants. The distribution of Phytoseiidae’s was primarily connected with the possibility of their movement along the surface of the substrate. Speed of mites moving was not the same in different species and depended on their morphology and plant morphology. Both species lived and laid eggs on the underside of the leaf. K. aberrans was more commonly found near the central vein of the leaf, while E. finlandicus was observed more evenly on the leaf plate, which can be explained by it higher vagility. K. aberrans could inhabit high number on fruit varieties of plants with pubescence leaves. Morphological features of plant leaves did not affect the spread of E. finlandicus species, therefore, they could be considered more "universal". However, it reached a higher quantity on the plants with a smooth surface of a leaf plate. Certain temperature, illumination regime, air and soil humidity caused the differences in mites spreading at various habitats.
