Whole-genome assembly and annotation of the acorn weevil, Curculio nanulus (Coleoptera: Curculionidae).

ABSTRACT: The acorn weevil Curculio nanulus (Coleoptera: Curculionidae) is a seed predator that lays its eggs inside developing acorns and hickory nuts in the western United States. The female weevil uses her elongated rostrum to excavate a hole into the seed, creating a protected site for oviposition. Natural history traits among Curculio species-such as host specificity and variation in larval diapause-suggest a dynamic evolutionary relationship with their host plants. These traits are best studied through a comparative genomic framework, but such analyses cannot currently be undertaken due to the lack of whole-genome assemblies for Curculio species. To address this gap, we generated a whole-genome assembly for C. nanulus using PacBio HiFi sequencing. The resulting assembly is ∼1.5 Gbp in length,
