Wild populations of Triatoma infestans are highly connected to intra-peridomestic conspecific populations in the Bolivian Andes.

This geographical structure was fully confirmed by the topology of the neighbor-joining tree built from Cavalli Sforza’s genetic distances between wild and intra-peridomestic populations from the three localities, where the bootstrap values at the nodes grouping each locality were highly significant ( Figure 2 ).
