A chromosomal-level genome assembly of Corcyra cephalonica Stainton (Lepidoptera: Pyralidae)

The family Pyralidae is a large and important group within the superfamily Pyraloidea, consisting of more than 5,900 described species. The rice moth Corcyra cephalonica is a noteworthy pest affecting stored grains and products. However, the absence of high-quality genomes hinders our comprehension of the ecology of C. cephalonica. Herein, we propose a chromosome-level genome of C. cephalonica achieved through integrating Nanopore, Illumina, and Hi-C reads. The genome of 453.37 Mb in size consists of 98 scaffolds and 154 contigs, with a scaffold N50 size of 16.67 Mb. The majority of contigs (99.36%, 450.45 Mb) were effectively anchored to 29 chromosomes. The BUSCO analysis of the assembly revealed a completeness of 99.0% (n = 1,367), identifying 98.6% single-copy BUSCO genes and 0.4% duplicated BUSCO genes. Furthermore, the genome contains 48.74% (220.96 Mb) repeat elements and encompasses 14,135 predicted protein-coding genes. This study offers a valuable genomic foundation for advancing our comprehension of the biology of C. cephalonica.
