Distribution of Ticks from of the Genus Dermacentor (Acari, Ixodidae) in Ukraine. Akimov I. A., Nebogatkin I. V. -The northern border of present range of the tick species Dermacentor marginatus is determined on the territory of Ukraine in Volyn, Rivne, Khmelnytsky, Zhytomyr, Kyiv, Cherkasy, Poltava and Sumy oblasts. D. reticulatus species was revealed to be adapted for living in urbanized areas as parasitizing domestic and stray animals, small mammals. It also inhabits shores of artificial reservoirs and occurs in the steppe zone, except for arid areas. D. reticulatus preimaginal stages are found for the first time on birds (Anas platyrhynchos, Sturnus vulgaris, Turdus merula, T. viscivorus).K e y w o r d s: ticks, Acari, Ixodidae, Dermacentor, D. marginatus, D. reticulatus, urbanized areas, Ukraine.Ðàñïðîñòðàíåíèå èêñîäîâûõ êëåùåé ðîäà Dermacentor (Acari, Ixodidae) â Óêðàèíå.

Ixodid Ticks (Acari, Ixodidae) in Urban Landscapes. A review. Akimov, I. A., Nebogatkin, I. V. -Th is study presents the results of content analysis of published works on ixodid ticks in urban conditions in order to determine the species diversity, the vectors of research interests at various stages. Information about ticks in the cities up to the 1980s is incidental, to the point of exclusive, aft er this point there is targeted research in urban landscapes. Th ere are 106 or 15 % of hard ticks of the world fauna registered in the urban territory, 26 species or 3.7 % being the most abundant. Of the urban hard tick species, 23 (88.5 %) can attack humans, and 12 species are the most adapted to the urban landscape: Ixodes ricinus, I. persulcatus, Dermacentor reticulatus, D. marginatus, I. pavlovskyi, I. scapularis (dammini), Amblyomma cajennense, Haemaphysalis longicornis, I. hexagonus, Hyalomma marginatum, Am. americanum, and Rhipicephalus sanguineus. It was determined that the most likely causes of the growing number of publications on ixodids urban landscapes are: global accelerating urbanization, the development of recreational areas, the development of green tourism, the growth of the prestige of outdoor recreation, the creation of new, especially of the landscape parks and a tendency to preserve the native landscape in the cities, a signifi cant increase in the density of populations of common species of hard ticks adapted to living in urban environment. Th e vectors of further work in urban landscapes will be directed to exact planning of monitoring studies of ixodids and associated tick-borne infections.K e y w o r d s : ticks, city, tick-borne infection, urban landscapes.
