The sugarcane borer (Diatraea saccharalis), a widely distributed moth throughout the Americas, is a pest that affects economically important crops such as sugarcane, sorghum, wheat, maize and rice. Given its relevant impact on yield production, whole-genome information of the species is needed. Here, we report a first draft assembly of the D. saccharalis genome. The 453 Mbp assembled sequences contain 1,445 BUSCO gene orthologs and 1,161 predicted gene models identified based on homology to the domestic silk moth, Bombyx mori. The repeat content composes 41,18% of the genomic sequences which is in the range of other Lepidopteran species. Interestingly, functional annotation reveals that predicted proteins are involved in important cellular mechanisms such as metabolic pathways and protein synthesis. Finally, the data generated in this study expands our knowledge on the genomic characteristics of this devastating insect pest and provides an essential resource for future genetic studies of the species.
