摘要： Long-distance migratory insects carry microorganisms that can potentially play a crucial role in the life cycles of their hosts. Here, we used Illumina and Sanger sequencing to determine the complete genome sequence of a novel circular Rep-encoding single-stranded (ss) DNA virus from an important migratory pest, Agrotis ipsilon (Hufnagel). The full genome of this new virus is about 2, 242 nt in length and shares 55-75% genome-wide pairwise sequence identity with members of the family Genomoviridae but 91% nucleotide sequence identity with finch-associated genomovirus 3 isolate S30P_D, which is tentatively abbreviated "FaGmV-3". Viral infection rates in A. ipsilon from Yantai, Langfang and Xinxiang were 4.5% (n = 88), 11.8% (n = 85) and 0% (n = 35), respectively. Phylogenetic analysis based on the deduced amino acid sequence of Rep indicated that the Agrotis ipsilon-associated virus is closely related to members of the genus Gemykibivirus, and we propose it to be a new member of this genus. Hence, it is tentatively named "Agrotis ipsilon-associated genomovirus" (AiGmV).
