Abstract

The presence of Triatoma rubrovaria in Brazil has only been confirmed in the States of Parana and Rio Grande do Sul (RS), where it is found naturallyinfected with Trypanosoma cruzi. In the wild environment it occurs in rocky habitats and has an eclectic diet, feeding from cockroaches, reptiles andmammals. Data from the Chagas Disease Control Program obtained by the Fundacao Nacional de Saude, between 1975 and 1997. indicate a growing domiciliary and peridomiciliary invasion of T. rubrovaria in RS, where it has becomethe most frequently Triatominae species captured in this state since the control of Triatoma infestans. In order to monitor this process, we analyzedcollection data der derived from 22 years of control campaigns against T. infestans. Collection data for triatomines from domestic habitats show an inverse relationship, with high numbers of T. infestans and low numbers of T. rubrovaria during 1976-1987 compared to the following ten years, 1986-1997 when the number of T. infestans dropped drastically and that of T. rubrovaria increased. There are no consistent indications of intradomiciliary colonization by T. rubrovaria, since only low numbers of nymphs have been captured in the intradomiciliary ecotopes. Nevertheless, this species appears to have preadaptive characteristics for anthropic ecotopes. and should be kept under constant epidemiological surveillance.
