Chromosome-level genome assembly of Cyamophila willieti (Hemiptera: Psyllidae)

Cyamophila willieti (Hemiptera: Psyllidae) is a significant pest that adversely affects the growth of Styphnolobium japonicum and its variant, Styphnolobium japonicum f. pendula. Despite its impact, research on this species remains limited. In this study, we successfully assembled a chromosome-level genome for Cyamophila willieti using a comprehensive approach that integrated Illumina sequencing, PacBio sequencing, and Hi-C technology. The genome size was determined to be 361.61 Mb, with a scaffold N50 length of 28.90 Mb. Additionally, the genome was mapped to 13 chromosomes (N = 12 A + X), and a total of 15,841 genes were predicted, with 90.38% of them functionally annotated. In summary, the high-quality genome of Cyamophila willieti provides valuable data to support further research, including pest management strategies.
