Population dynamics and feeding behavior of Triatoma brasiliensis and Triatoma pseudomaculata, main vectors of Chagas disease in Northeastern Brazil
Population dynamics and feeding behavior of Triatoma brasiliensis and Triatoma pseudomaculata, main vectors of Chagas disease in Northeastern Brazil
Biological parameters of Triatoma brasiliensis and T. pseudomaculata
that could influence the epidemiological importance of these insects as
vectors of Trypanosoma cruzi were compared. The parameters studied were
incubation period, interval between hatching or moulting and first
feeding, number of blood meals, development time, mortality, net
reproductive rate, instantaneous daily reproductive rate, time-lapse
before starting feeding, duration of feeding, blood ingestion capacity,
occurrence of defecation and blood ingestion velocity. Most aspects of
feeding were similar for the two species, although T. pseudomaculata
had a longer life cycle than T. brasiliensis producing one and two
generations per year, respectively. The two species had similar
instantaneous daily rates of population growth
