Trabala vishnou (Lefèbvre, 1827) (Lepidoptera: Lasiocampidae) is a destructive leaf-eating pest that causes severe damage to forest ecosystems, leading to substantial economic losses. Herein, we sequenced and assembled a high-quality chromosome-level genome of T. vishnou using a combination of Illumina reads, PacBio HiFi reads, and High throughput Chromosome Conformation Capture (Hi-C) technologies. The genome size is 561.86 Mb and spans 25 chromosomes, exhibiting a high level of contiguity (scaffold/contig N50 = 21.75 Mb/20.67 Mb). Benchmarking Universal Single-Copy Orthologs (BUSCO) analysis a 99.5% completeness score for this genome assembly. Repeat elements constitute 62.66% of the genome. A total of 1,630 non-coding RNAs and 12,895 protein-coding genes have been identified within the genome. The first chromosome-level genome of T. vishnou serves as a valuable reference for elucidating the evolution of functional traits in Lasiocampidae family and will facilitate the development of strategies for controlling defoliating pests.
维氏裳夜蛾（Lefèbvre，1827年）（鳞翅目：枯叶蛾科）是一种具有破坏性的食叶害虫，会对森林生态系统造成严重破坏，导致重大经济损失。在此，我们结合Illumina reads、PacBio HiFi reads和高通量染色体构象捕获（Hi-C）技术，对维氏裳夜蛾进行了高质量染色体水平的基因组测序和组装。基因组大小为561.86 Mb，跨越25条染色体，具有高度的连续性（支架/重叠群N50 = 21.75 Mb/20.67 Mb）。基准通用单拷贝直系同源基因（BUSCO）分析表明该基因组组装的完整性得分为99.5%。重复元件占基因组的62.66%。基因组中总共鉴定出1630个非编码RNA和12895个蛋白质编码基因。维氏裳夜蛾的首个染色体水平基因组为阐明枯叶蛾科功能性状的进化提供了有价值的参考，并将有助于制定控制食叶害虫的策略。
