Feeding patterns of Triatoma infestans (Hemiptera: Reduviidae) in relation to transmission of American trypanosomiasis in Argentina
Agar double diffusion tests were used to analyze the origin of blood meals from 720 Triatoma infestans bugs collected from bedrooms and peridomestic structures of 9 households near Guanaco Muerto in the Province of Cordoba, Argentina. The intestinal contents of 332 (46.1%) of the bugs reacted to 1 o...

The higher rates of infection with Trypanosoma cruzi were found in bugs from bedrooms (63.6%). Peridomestically collected bugs from storerooms, chicken houses and goat pens showed significantly lower rates of infection (25, 2.4 an 1.4%, respectively). In bugs collected from bedrooms, a high correlation occurred between identified feedings from dogs and the rate of infection with T. cruzi. Dogs were considered the most important host, both as a reservoir source of T. cruzi and in the maintenance of domicilliary T, infestans in the study area.
