Geographic origin of Acanthoscelides obtectus (), A. obvelatus (▽), A. argillaceus (
) and Zabrotes subfasciatus (
) individuals sampled. (a) Pacific coast populations; only one cytb gene is present in Z. subfasciatus populations (SJB, ELA). (b) Altiplano populations; two cytb genes are present in the same individual in some Z. subfasciatus (OCM, YAU, TLA); (c) population of origin of the Z. subfasciatus laboratory colony.
