Abstract

The biting midges 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 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 species were grouped into eight pools and subjected to metagenomic analysis. Eight new insect-specific viruses (ISVs) were characterized and assigned to the order , the families , , , , and and the taxon . All viruses identified were assigned to clades, families and taxa never reported in 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.

摘要

蠓科（双翅目：蠓科）昆虫与流行病学和公共卫生高度相关，因为其中包括一些物种，它们是人类和动物虫媒病毒的潜在传播媒介。本研究的目的是调查在帕拉州卡拉雅斯矿区采集的蠓属物种中RNA病毒的存在情况。在卡纳安杜斯卡拉雅斯、库里奥诺波利斯和马拉巴等市采集了蠓，并进行了形态学鉴定。总共1139只属于7个物种的标本被分成8组，进行宏基因组分析。鉴定并表征了8种新的昆虫特异性病毒（ISV），它们被归类到目、科、科、科、科、科和分类单元。所有鉴定出的病毒都被归类到巴西从未在蠓科中报道过的进化枝、科和分类单元。这项研究表明，蠓携带大量RNA病毒，其中许多仍然未知，突出了针对这些昆虫病毒组的研究的重要性。
