摘要

Nadezhdiella cantori (Coleoptera: Cerambycidae) is a wood-boring pest native to Southeast Asia that attacks citrus trees, with larvae boring into trunks and branches and often causing tree mortality. Nevertheless, the absence of a high-quality genome has hindered ecological research and the development of effective pest management for N. cantori. In this study, we report the assembly of a chromosome-level genome for N. cantori, generated by integrating PacBio, Illumina, and Hi-C sequencing data. The assembled genome is 737.74 Mb in size, comprising 30 scaffolds and 943 contigs, with scaffold and contig N50 values of 87.91 Mb and 1.33 Mb, respectively. In total, 97.88% (722.07 Mb) of the genome was assigned to 10 chromosomes. BUSCO analysis using the insecta_odb10 dataset (n = 1,367) revealed the genome assembly completeness of 99.3%, including 98.1% single-copy and 1.2% duplicated BUSCOs. We identified repetitive elements constituting 61.20% (451.48 Mb) of the genome and predicted 14,883 protein-coding genes. This genome serves as a valuable resource for N. cantori’s adaptations and developing wood-boring pest control.
