We sampled seven Ostrinia furnacalis (Guenée) populations across 23 degrees of latitude in China to elucidate the genetic basis of diapause variation and evolutionary mechanisms driving parallel clinal responses. Using pooled whole-genome sequencing (Pool-seq) data, population genomic analyses revealed hundreds of single nucleotide polymorphisms (SNP) whose allele frequencies covaried with mean diapause phenotypes along the cline. Archived on Dryad are the custom R scripts used in the population genomic analyses as well as the mapping of O. furnacalis scaffolds to Bombyx mori reference chromosomes (for visualizing population genetic statistics across chromosomes).
