Fedyay I. Taxonomy, ecology and bionomy of terrestrial hemipterans (Hemiptera, Heteroptera) of metropolis urban coenoses

Thesis paper is devoted to the study of one of the dominant and peculiar components of the entomofauna of Ukraine, representatives of the suborder of hemipterans (Heteroptera) within the urban coenoses of the metropolis. Over the last 30 years, information on the species composition and ecological characteristics of many species of true bugs in natural ecosystems is extremely fragmentary. Transformed urban ecosystems remain unexplored, which led to the relevance of this study. The scientific novelty of the work is that for the first time the species composition of the order Heteroptera of Kharkiv was established – 180 species of hemipterans of 120 genera and 17 families, of which Xylocoris (Proxylocoris) galactinus (Fieber, 1836) (Anthocoridae) was indicated for the first time for mainland Ukraine; for the Forest-Steppe – Catoplatus nigriceps Horváth, 1905 (Tingidae), Stenodema (Stenodema) holsata (Fabricius, 1787) (Miridae); for the Left Bank of Ukraine – Carpocoris (Carpocoris) purpureipennis (De Geer, 1773) (Pentatomidae) and Trigonotylus ruficornis (Geoffroy, 1785) (Miridae). Four species of the family Lygaeidae – Nysius ericae (Schilling, 1829), Perithrechus geniculatus (Hahn, 1832), Perithrechus gracilicornis Puton, 1877, Taphropeltus contractus (Herrich-Schäffer, 1835) and five species of the family Miridae – Amblytylus nasutus (Kirschbaum, 1856), Deraeocoris lutescens (Schilling, 1837), Globiceps (Kelidocoris) flavomaculatus (Fabricius, 1794), Notostira elongata (Geoffroy, 1785) and Pilophorus perplexus Douglas et Scott, 1875 were new to the Kharkiv region. For the first time, the qualitative and quantitative characteristics of hemipterans families depending on the peculiarities of the urbocenosis were analyzed. For the first time for megapolises the ecological structure was studied and the zoogeographical analysis of heteropterofauna was carried out. The life cycles of background species of true bugs in the conditions of Kharkiv have been specified. A detailed analysis of the spatial (tier) distribution of Heteroptera in Kharkiv was performed. For the first time, the bioindication capabilities of hemipterans in the city were assessed.
