Phylogenetic patterns. a. Phylogenetic relationships between different populations of Acanthoscelides obtectus (
), A. obvelatus (â–½), A. argillaceus (
) and Zabrotes subfasciatus (
) for the mitochondrial COI gene. An identical topology is supported by 28S rRNA (not shown); b. Phylogenetic relationships between different populations of Acanthoscelides obtectus (), A. obvelatus (▽), A. argillaceus () and Zabrotes subfasciatus () for the cytb gene. Underlined individuals correspond to Z. subfasciatus populations from the Mexican Altiplano – some carry two cytb haplotypes. Stars (*) indicate Z. subfasciatus haplotypes identical to haplotypes from Acanthoscelides. "Z. subfasciatus CLNY" corresponds to an individual of the laboratory colony affected by HGT.
