Omiodes indicata, a significant pest of legumes, impacts food security in tropical and subtropical regions of Asia, Africa, and the Americas Asia. However, the lack of high-quality genomes has limited our understanding of the ecology of O. indicata. In this study, we present a high-quality genome assembly of O. indicata generated using advanced sequencing technologies, including PacBio HiFi long reads, Illumina short-read, and Hi-C platforms. The final assembly spans 493.08 Mb, comprising 59 scaffolds (scaffold N50: 17.25 Mb) and 100 contigs (contig N50: 15.72 Mb), with 99.80% of the total assembly (492.12 Mb) successfully anchored to 31 chromosomes. BUSCO analysis (n = 1,367) indicates a high level of completeness, with 99.1% of genes detected: 96.6% as single-copy and 2.5% as duplicated. Repetitive elements constitute 38.13% (188.00 Mb) of the genome, and 14,713 protein-coding genes were predicted. The high-quality O. indicata genome represents a valuable resource for diverse molecular ecology studies and will contribute to the advancement of modern pest management strategies.
印度赭夜蛾是豆类作物的一种重要害虫，影响着亚洲、非洲和美洲亚洲热带和亚热带地区的粮食安全。然而，缺乏高质量的基因组限制了我们对印度赭夜蛾生态学的理解。在本研究中，我们展示了利用先进测序技术生成的高质量印度赭夜蛾基因组组装结果，这些技术包括PacBio HiFi长读长测序、Illumina短读长测序和Hi-C技术平台。最终组装的基因组跨度为493.08 Mb，由59个支架（支架N50：17.25 Mb）和100个重叠群（重叠群N50：15.72 Mb）组成，总组装的99.80%（492.12 Mb）成功锚定到31条染色体上。BUSCO分析（n = 1367）表明完整性水平很高，检测到99.1%的基因：96.6%为单拷贝基因，2.5%为重复基因。重复元件占基因组的38.13%（188.00 Mb），预测有14713个蛋白质编码基因。高质量的印度赭夜蛾基因组是各种分子生态学研究的宝贵资源，将有助于推进现代害虫管理策略。
