摘要： European corn borer Ostrinia nubilalis (H & uuml;bner) is the most important pest of maize around world, and an ideal model for the sympatric host races, evolutionary and speciation research. In this study, we assembled a chromosome-level genome of Z strain O. nubilalis by the integrated Illumina short reads, PacBio Revio long reads, and Hi-C sequencing data. The chromosome-level genome was 480.04 Mb in total length with a contig N50 length of 16.51 Mb, which 98.59% genome anchored into 31 chromosomes. For the annotation, 1,046,695 repeat sequences in length of 212.07 Mb, 1,550 non-coding RNAs (including 1,208 tRNAs, 179 rRNAs, 62 miRNAs, 81 snRNAs, and 20 snoRNAs), and 17,145 protein-coding genes were identified. And 100% genes were functional annotated by SwissProt, NR, eggNOG, Go, and KEGG database. This genome provides a valuable genomics resource to elucidate the host plant adaptation, thermal adaptation, diapause induction, Bacillus thuringiensis toxin resistance, sexual communication, sympatric host races, and speciation process of O. nubilalis.
