Abstract

This article focuses on the sequencing, assembly, and annotation of the genome of the Diaprepes root weevil (DRW), *Diaprepes abbreviatus*, an invasive agricultural pest in the southern United States and the Caribbean. The 1.69 Gb genome assembly revealed a high proportion of repetitive sequences and identified 20,235 genes, including a notably large expansion of glycoside hydrolase (GH) gene families involved in plant cell wall degradation, which may relate to the weevil’s polyphagy and invasiveness. Analysis of sex chromosome-linked contigs suggests a possible sex chromosome turnover event in DRW. The genome resource aims to facilitate the development of improved control strategies and to advance understanding of the genetic basis of specialized plant feeding and invasiveness in beetles.
