In addition to the traditional transmission route via the biting-and-defecating process, non-human host predation of triatomines is recognized as another significant avenue for Chagas disease transmission. In this paper, we develop an eco-epidemiological model to investigate the impact of predation on the disease's spread. Two critical thresholds, R (the basic reproduction number of triatomines) and R (the basic reproduction number of the Chagas parasite), are derived to delineate the model's dynamics.
