Chromosome-level genome assembly of Chouioia cunea Yang, the parasitic wasp of the fall webworm

<em>Chouioia cunea</em> Yang 1989 is a parasitic wasp of many lepidopteran insects during their pupal stage, and has been successfully used to control pests such as the fall webworm<em> Hyphantria cunea</em>. The total assembly length is 171.99 Mb, containing 6 chromosomes with a GC content of 36.89% and the scaffold/contig N50 length of 31.70/26.52Mb. A total of 12,258 protein-coding genes (PCGs), 10,547 3’-UTRs, and 10,671 5’-UTRs were annotated. The results revealed that a total of 26.06 Mb repeat sequences had been identified, accounting for 15.15% of the <em>C. cunea</em> genome. 431 noncoding RNAs (ncRNAs) were predicted, including 84 micro-RNAs (miRNAs), 97 ribosomal RNAs (rRNAs), 29 small nuclear RNAs (snRNAs), 16 small nucleolar RNAs (snoRNAs), and 205 transfer RNAs (tRNAs). In <em>C. cunea</em>, 11,691 (95.40%) genes were clustered into 9,204 gene families, of which 328 gene families were expanded, 360 gene families were contracted, and 54 (37 expansions and 17 contractions) gene families experienced rapid evolution.
