Abstract

The blood intake of Triatoma infestans (Klug 1834) and its relationship with the temperature (T) of the food source has been analyzed. The experimental device allows to change independently T of the feeder surface and of the blood contained. Rostral reflex and bite are evoked by the T of the feeder surface. Blood T influences the number of feeding insects. On the other hand, crop filling is independent of blood T, and is not an all-or-none process.
