Proportion of domestic T. infestans that fed on humans (HBI [human blood index]) according to the proportion of domestic bugs that fed on dogs or cats (a) (DCBI [dog-cat blood index]) and chickens (b) (CKBI [chicken blood index]). Each data point corresponds to a different house. The size of the circles is proportional to the frequency of reactive bugs. Avia Terai, Chaco, 2015–2016
