<b><i>Eocanthecona furcellata</i></b> genome data

<i>Eocanthecona furcellata</i> (Wolff.) (Hemiptera: Pentatomidae: Asopinae), a predatory stinkbug, preys on diverse notorious insect pests, positioning it as a critical biocontrol agent in agricultural and forestry ecosystems with substantial regional application and promotion potential. We present a chromosome-level genome assembly of <i>E. furcellata</i> using PacBio HiFi long-read sequencing and Hi-C scaffolding technologies. The final genome spans 1.13 Gb, with a contig N50 of 2.35 Mb and a scaffold N50 of 135.69 Mb, achieving 97.7% BUSCO completeness. Hi-C data resolved the assembly into 7 pseudochromosomes, representing the full karyotype. Repeat elements constitute 50.68% of the genome (approximately 520.07 Mb). We annotated 15,802 protein-coding genes, of which 90.72% were functionally assigned. This high-quality genome provides a foundational resource for advancing research on predatory bug biology, including genetic adaptations for digestion, molecular mechanisms of prey detection, and biocontrol optimization through functional genomics.

<i>Eocanthecona furcellata</i>（Wolff.）（半翅目（Hemiptera）：蝽科（Pentatomidae）：益蝽亚科（Asopinae），斑翅益蝽）是一种捕食性蝽类，可捕食多种重大农业害虫，是农林生态系统中关键的生防天敌，具备可观的区域应用与推广潜力。本研究利用PacBio HiFi长读长测序技术与Hi-C支架挂载技术，构建了斑翅益蝽的染色体级基因组组装。最终组装的基因组大小为1.13 Gb，重叠群N50为2.35 Mb，支架N50为135.69 Mb，BUSCO完整度达97.7%。Hi-C数据将组装序列锚定为7条假染色体，覆盖其完整核型。基因组中重复序列占比为50.68%（约520.07 Mb）。本研究共注释得到15802个蛋白质编码基因，其中90.72%获得了功能注释。该高质量基因组为捕食性蝽类的生物学研究提供了基础资源，涵盖消化相关遗传适应性、猎物识别分子机制，以及通过功能基因组学开展生防优化等研究方向。
