| Abstract | The importance of Rhodnius nasutus in the transmission of Chagas disease in northeastern Brazil was investigated regarding feeding and defecation patterns of this triatomine under laboratory conditions. An average of 30 samples were studied for each instar, from fourth-instar nymphs onward. On average, 86.4% started feeding after less than 10 minutes. In terms of the duration of feeding, 53.3% of fourth instar nymphs, 81.9% of fifth-instar nymphs, 21.9% of males, and 36.7% of females fed for more than 15 minutes. In all groups, there were insects that defecated and urinated during feeding; adult males defecated the most and fourth instar nymphs defecated the least. The results demonstrate that R. nasutus may be considered an efficient T. cruzi vector because it avidly searches for a food source, has a lengthy feeding time with low probability of interruption during feeding, and achieves a high percentage of engorgement. | pt_BR |
