SPECIES COMPOSITION OF BLOOD-SUCKING MOSQUITOES (DIPTERA, CULICIDAE) ARE CARRIERS OF VECTOR-BORNE DISEASES IN THE NIZHNEVARTOVSK DISTRICT OF THE KHANTY-MANSI AUTONOMOUS OKRUG

Abstract

The article summarizes the literature data and materials of our own research on the species composition of blood-sucking mosquitoes in the territory of the Nizhnevartovsk district of the Khanty-Mansi Autonomous Okrug and establishes the main species - vectors of various infectious and invasive diseases of humans and animals. Over the last few years, there has been a tendency for an increase in the incidence of tularaemia among the population of Khanty-Mansi Autonomous Okrug, which is carried by various species of blood-sucking mosquitoes. Due to swampy and waterlogged territory of the study area, this terrain is favorable for the development of mosquitoes and the spread of the pathogen, in particular tularaemia. Own collections were made on the island Sherm, Nizhnevartovsk district, in two open biotopes - a wet meadow and the bank of a stream. The studies resulted in an annotated list including 34 species of blood-sucking mosquitoes, of which 16 were found during own collections. The dominant species were Ae. (Och) communis (ID = 29%) and Ae. (Och) punctor (ID = 20%). A new species, Ae. (Och) subdiversus, not previously found in the area, was found.  Most of the species found so far in the study area are potential vectors of various vector-borne human and animal diseases, such as tularemia, West Nile fever, dirophylyariasis, Omsk hemorrhagic fever, etc. Ae. (Och) communis, Ae. (Och) flavescens, Ae. (Och) cyprius, Ae. (Och) punctor, Ae. (Och) dorsalis, Ae. (Och) excrucians, Ae. vexans vexans are involved in the spread of tularemia pathogen.
