Episyrphus balteatus can provide dual ecosystem services including pest control and pollination, which the larvae are excellent predators of aphid pest whereas adults are efficient pollinator. In this study, we assembled a high-quality genome of E. balteatus from northern China geographical population at the chromosome level by using Illumina, PacBio long reads, and Hi-C technologies. The 467.42 Mb genome was obtained from 723 contigs, with a contig N50 of 9.16 Mb and Scaffold N50 of 118.85 Mb, and 90.25% (431.75 Mb) of the assembly was anchored to 4 pseudo-autosomes and one pseudo-heterosome. In total, 14,848 protein-coding genes were annotated, and 95.14% of genes were fully represented in NR, GO, KEGG databases. Besides, we also obtained the mitochondrial genome of E. balteatus of 16, 837 bp in length with 37 typical mitochondrial genes. Overall, this high-quality genome is valuable for evolutionary and genetic studies of E. balteatus and other Syrphidae hoverfly species.
跳小蜂属的巴氏短翅跳小蜂可以提供双重生态系统服务，包括控制害虫和授粉，其幼虫是蚜虫害虫的优秀捕食者，而成虫则是有效的传粉者。在这项研究中，我们利用 Illumina、PacBio 长读长和 Hi-C 技术，从中国北方的地理种群中组装了巴氏短翅跳小蜂的高质量染色体水平基因组。该 467.42Mb 基因组由 723 个 contigs 组成，contig N50 为 9.16Mb，Scaffold N50 为 118.85Mb，组装的 90.25%（431.75Mb）锚定在 4 条假常染色体和 1 条假异染色体上。总共注释了 14848 个蛋白编码基因，其中 95.14%的基因在 NR、GO、KEGG 数据库中完全有代表。此外，我们还获得了巴氏短翅跳小蜂的线粒体基因组，长度为 16837bp，包含 37 个典型的线粒体基因。总的来说，这个高质量的基因组对巴氏短翅跳小蜂和其他食蚜蝇科昆虫的进化和遗传研究具有重要价值。
