Chromosome-level genome assembly of the pine shoot beetle Tomicus yunnanensis

The pine shoot beetle, Tomicus yunnanensis (Curculionidae: Scolytinae), is a significant trunk-boring pest of Pinus yunnanensis forests, causing extensive ecological degradation through direct feeding and its role as a vector for destructive pathogenic fungi. The scarcity of a high-quality reference genome has hindered in-depth studies of its biology, particularly the mechanisms underlying its pathogen transmission and host adaptation. Here, we report a chromosome-level genome assembly of T. yunnanensis. Using a combination of PacBio long-read sequencing, Illumina short-read sequencing, and Hi-C chromatin interaction mapping, we generated a final genome assembly of 379.3 Mb, which was anchored into 14 linkage pseudo-chromosomes, with scaffold N50 value of 21.6 Mb. A total of 12, 941 protein coding genes were predicted and annotated. BUSCO completeness assessment indicated that the completeness of the assembly and annotation reached 96.4% and 95.3%, respectively. This high-quality genome provides a critical resource for future research on the pest's biology, ecological adaptation, management and will ultimately support the development of targeted strategies to control its damage and disrupt its role in pathogen dissemination.
