Blood Temperature and Feeding Behavior in Triatoma infestans (Heteroptera: Reduviidae)
Lazzari, Claudio Ricardo; Nunez, Josue Antonio
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.
