Observed and expected heterozygosity at diagnostic pgfar SNP loci assayed by PCR-RFLP from Ostrinia nubilalis adults collected by light traps at indicated locations. Site IDs correspond to those on the map in Figure 1. BENY colony adults are included as a control for monomorphic E-race. NA = not applicable.

¹Significant at 0.05 level.
