摘要

The bumblebee Bombus patagiatus Nylander, 1848 and Bombus lantschouensis Vogt, 1908 (Hymenoptera: Apidae) are ecologically important bumble bee species native to East Asia, with considerable value for agricultural pollination and domestication. Despite their ecological and economic relevance, the lack of high-quality genomic resources has hindered in-depth investigations into their genetic architecture and evolutionary adaptations. Here, we present chromosome-level genome assemblies for both species, generated using a combination of PacBio HiFi long-read sequencing, Illumina short-read resequencing, and Hi-C scaffolding. The assembled genomes span 240.28 Mb (B. patagiatus) and 241.30 Mb (B. lantschouensis), with 94.38% and 94.00% of sequences anchored to 18 chromosomes, respectively. Genome annotation identified 17,351 and 16,023 protein-coding genes in B. patagiatus and B. lantschouensis, along with comprehensive repetitive element characterization. Both assemblies exhibit exceptional completeness, with BUSCO scores exceeding 99%, confirming their high quality and reliability. These genomic resources provide a critical foundation for future research on bumble bee evolution, population genetics, and the molecular basis of domestication traits.
