Evidence of selection on phenotypic plasticity and cost of plasticity in response to host-feeding sources in the major Chagas disease vector Triatoma infestans

[Display omitted] •We conducted experiments on adaptive phenotypic plasticity in Triatoma infestans.•Wings exhibited differences in phenotypic plasticity related to host-feeding source.•Selection on plasticity was detected only in females fed on guinea pigs.•Costs of plasticity were detected for tra...
