The Origin of the Northern Palaearctic Fauna of Bloodsucking Insects, by the Example of Fleas (Siphonaptera), Mosquitoes (Diptera: Culicidae), and Blackflies (Diptera: Simuliidae)

摘要

AbstractThe territory of Fennoscandia and northwestern European Russia was released from the glacier cover in the Upper Pleistocene and has been recolonized by bloodsucking insects during the last 11 thousand years. The sources of formation of the Northern Palaearctic fauna of such groups of bloodsucking insects as fleas (Siphonaptera), mosquitoes (Culicidae), and blackflies (Simuliidae) were different in the postglacial period. One of the sources was the fauna of the ancient Mediterranean and southern Europe, while others were the faunas of northeastern China and Primorye. In turn, the two latter sources are closely related to the ancient faunal centers of the East Asian Subregion of the Palaearctic and also of the Indomalayan Region. Besides, some species and genera have spread from the West American Subregion of the Nearctic through Beringia.]]>
