Trichogramma spp. is a genus of minute egg parasitoids frequently used in agricultural pest management that can feed on the eggs of various lepidopteran pests. Currently, there is a scarcity of high-quality genomic resources for this category of tiny parasitoids, which impedes our comprehension of the population evolution and parasitic ecology of this collective. In this case, a chromosome-level genome of Trichogramma chilonis was produced by integrating PacBio HiFi, Illumina, and Hi-C data. The genome size totals 202.48 Mb, with a scaffold N50 length of 40.00 Mb. A total of 98.59% (199.63 Mb) of contigs were effectively mapped onto five chromosomes. The BUSCO assessment revealed that the genome assembly achieved 98.1% (n = 1,367) completeness, with 95% representing single-copy BUSCOs and 3.1% duplicated BUSCOs. Also, the genome comprises 24.16% (48.91 Mb) repeat elements and 12,163 predicted protein-coding genes. The high-quality genome of T. chilonis presented in this study offers an invaluable asset for elucidating its evolutionary path and ecological interactions.
赤眼蜂属是一类微小的卵寄生蜂，常用于农业害虫管理，能够取食多种鳞翅目害虫的卵。目前，这类微小寄生蜂缺乏高质量的基因组资源，这阻碍了我们对其种群进化和寄生生态学的理解。在此情况下，通过整合PacBio HiFi、Illumina和Hi-C数据，构建了稻螟赤眼蜂的染色体水平基因组。基因组大小总计202.48 Mb，支架N50长度为40.00 Mb。共有98.59%（199.63 Mb）的重叠群有效地定位到了五条染色体上。BUSCO评估显示，基因组组装的完整性达到98.1%（n = 1,367），其中95%为单拷贝BUSCO，3.1%为重复BUSCO。此外，基因组包含24.16%（48.91 Mb）的重复元件和12,163个预测的蛋白质编码基因。本研究中展示的稻螟赤眼蜂高质量基因组为阐明其进化路径和生态相互作用提供了宝贵资源。
