| Abstract | Data from the Chagas Disease Control Program indicate a growing domiciliary and peridomiciliary invasion of
Triatoma rubrovaria in the State of Rio Grande do Sul, where it has become the most frequent triatomine species
captured there since the control of T. infestans. Bionomic characteristics that could influence the vectorial capacity
of T. rubrovaria as vector of Trypanosoma cruzi were evaluated: patterns of (i) feeding, (ii) defecation, and (iii)
resistance to starvation, using insects fed on mice. Fifty three percent of the females showed a defecation pattern
conducive to chagasic transmission, defecating either on or near the bite site. The averages of the resistance to
starvation varied from 48.1 to 179 days, for the first and fifth nymphal stages, respectively. Our study shows that with
respect to the patterns of feeding, defecation and resistance to fasting, T. rubrovaria presented similar rates to the
ones observed for other effective vector species, such as T. infestans. Thus, based on our studies we conclude that
T. rubrovaria has biological characteristics that can positively influence its capacity to become infected and transmit T. cruzi, and also to keep residual populations after chemical control interventions. | pt_BR |
