High-throughput sequencing is widely used for virus discovery, and many RNA viruses have been discovered and identified. A new negative-sense single-stranded RNA virus was identified in the brown citrus aphid and named Aphis citricidus bunyavirus. The genome consists of large (7037 nt), medium (3462 nt), and small (1163 nt) segments. Phylogenetic analysis and amino acid sequences identities of this virus with other bunyaviruses suggest that it is a new species belonging to the family Phenuiviridae. The small interfering RNA pathway could be involved against the infection of this virus in brown citrus aphid as supported by the viral derived small RNAs. The discovery of this virus illustrates the diversity of RNA viruses and contributes to the classification of bunyaviruses.
高通量测序被广泛用于病毒发现，许多RNA病毒已被发现和鉴定。在褐橘蚜中鉴定出一种新的负义单链RNA病毒，并将其命名为柑橘蚜本扬病毒。该病毒基因组由大片段（7037 nt）、中片段（3462 nt）和小片段（1163 nt）组成。系统发育分析以及该病毒与其他本扬病毒的氨基酸序列一致性表明，它是属于白蛉病毒科的一个新物种。病毒衍生的小RNA表明，小干扰RNA途径可能参与褐橘蚜对这种病毒感染的抵抗。该病毒的发现说明了RNA病毒种类的多样性，并有助于本扬病毒的分类。
