The Asian corn borer (Ostrinia furnacalis), a major economic pest of crops such as corn, sugarcane, millet, and sorghum, is widely distributed from Asia to the western Pacific islands. Its broad distribution and polyphagous traits are largely due to its larval diapause, which allows survival during winter. To facilitate genetic studies on its adaptability, we generated a high-quality genome assembly for O. furnacalis using Illumina, PacBio, and Hi-C technologies. The assembled 481.9 Mb genome comprises 135 scaffolds with an N50 of 16.6 Mb, and 98.5% of the sequences were assigned to 31 chromosomes through Hi-C scaffolding. Gene prediction identified 16,272 genes, with 97.0% completeness based on BUSCO assessment. This chromosome-level genome assembly and gene annotation provide an invaluable resource for studying the genetic variation of O. furnacalis and offer new insights into its diapause mechanism and adaptability.
亚洲玉米螟（Ostrinia furnacalis）是玉米、甘蔗、粟和高粱等作物的主要经济害虫，广泛分布于从亚洲到西太平洋岛屿的地区。其广泛的分布和多食性特征很大程度上归因于其幼虫滞育，这使其能够在冬季存活。为了便于对其适应性进行遗传学研究，我们利用Illumina、PacBio和Hi-C技术为亚洲玉米螟生成了一个高质量的基因组组装。组装得到的481.9 Mb基因组由135个支架组成，N50为16.6 Mb，并且通过Hi-C支架构建，98.5%的序列被定位到31条染色体上。基因预测鉴定出16272个基因，基于BUSCO评估，完整性为97.0%。这种染色体水平的基因组组装和基因注释为研究亚洲玉米螟的遗传变异提供了宝贵资源，并为其滞育机制和适应性提供了新的见解。
