Callosobruchus maculatus is one of the most competitive stored grain pests, which causes a great loss to agricultural economy. However, due to an inadequacy of high-quality reference genome, the molecular mechanisms for olfactory and hypoxic adaptations to stored environments are unknown and require to be revealed urgently, which will contribute to the detection and prevention of the invasive pests C. maculatus. Here, we presented a high-quality chromosome-level genome of C. maculatus based on Illumina, Nanopore and Hi-C sequencing data. The total size was 1.2 Gb, and 65.17% (797.47 Mb) of it was identified to be repeat sequences. Among assembled chromosomes, chromosome 10 was considered the X chromosome according to the evidence of reads coverage and homologous genes among species. The current version of high-quality genome provides preferable data resources for the adaptive evolution research of C. maculatus.
斑豆象是一种极具竞争力的仓储害虫，对农业经济造成了巨大损失。然而，由于高质量参考基因组的不足，其对仓储环境的嗅觉和低氧适应的分子机制尚不清楚，急需揭示，这将有助于检测和预防入侵害虫斑豆象。在这里，我们基于 Illumina、Nanopore 和 Hi-C 测序数据呈现了一个高质量的斑豆象染色体水平基因组。总大小为 1.2Gb，其中 65.17%（797.47Mb）被鉴定为重复序列。在组装的染色体中，根据读段覆盖和种间同源基因的证据，第 10 号染色体被认为是 X 染色体。目前高质量基因组的版本为斑豆象的适应性进化研究提供了更好的数据资源。
