ABSTRACT
The pink stem borer, Sesamia inferens Walker (Lepidoptera: Noctuidae), is one of the most notorious pest insects of rice and maize crops in the world. Here, we generated a high-quality chromosome-level genome assembly of S. inferens, using a combination of Illumina, PacBio HiFi and Hi-C technologies. The total assembly size was 973.18 Mb with a contig N50 of 33.39 Mb, anchored to 31 chromosomes, revealing a karyotype of 30 + Z. The BUSCO analysis indicated a high completeness of 98.90% (n = 5286), including 5172 (97.8%) single-copy BUSCOs and 58 (1.1%) duplicated BUSCOs. The genome contains 58.59% (564.58 Mb) repeat elements and 26628 predicted protein-coding genes. The chromosome-level genome assembly of S. inferens provides in-depth knowledge and will be a helpful resource for the Lepidoptera and pest control research communities.
