Abstract
Diabrotica undecimpunctata ssp. howardi, the southern corn rootworm or eastern 12-spotted cucumber beetle, is a generalist insect herbivore that causes damage and yield loss to several crops in North America including maize. Unresolved phylogenetic relationships within and among D. undecimpunctata subspecies are impacting current quarantine policies. We report the chromosome-level haploid genome a…
