Description
Summary:The biting midges <i>Culicoides</i> Latreille, 1809 (Diptera: Ceratopogonidae) is highly relevant to epidemiology and public health, as it includes species that are potential vectors of human and animal arboviruses. The aim of this study was to investigate the presence of RNA viruses in species of the genus <i>Culicoides</i> collected in the Carajás mining complex in the state of Pará. The biting midges were collected in the municipalities of Canaã dos Carajás, Curionópolis and Marabá and morphologically identified. A total of 1139 specimens of seven <i>Culicoides</i> species were grouped into eight pools and subjected to metagenomic analysis. Eight new insect-specific viruses (ISVs) were characterized and assigned to the order <i>Tolivirales</i>, the families <i>Chuviridae</i>, <i>Nodaviridae</i>, <i>Iflaviridae</i>, <i>Mesoniviridae</i>, and <i>Flaviviridae,</i> and the taxon <i>Negevirus</i>. All viruses identified were assigned to clades, families and taxa never reported in <i>Culicoides</i> in Brazil. This study demonstrated that biting midges harbor a significant diversity of RNA viruses, many of which are still unknown, highlighting the importance of studies aiming at virome of these insects.
