“…Triatoma sordida usually occupies places where Triatoma infestans has been eliminated due to the residual effects of the insecticides adopted by the control programs. This species, as well as Panstrongylus megistus, has been captured in both wild and urban ecotopes, frequently constituting domestic colonies 15,22,23 . In other studies, however, this species presented low rates of positivity for Trypanosoma cruzi, probably because it prefers to feed on the blood of birds 1,24 .…”

INTRODUCTION: from an epidemiological point of view, more than 120 species of triatomine (Hemiptera, Reduviidae) are known. The occurrence and positivity for Trypanosoma cruzi in triatomines in 16 municipalities of the Triângulo Mineiro and Alto Paranaíba were evaluated from January 2002 to December 2004. METHODS: the triatomines were captured basically according to the classic norms of the National Health Foundation. The parasitological exams of the triatomines were conducted according to the technique described by the Ministry of Health. During the study period, 990 specimens of triatomines were captured and of these, 771 could be examined. RESULTS: five species were identified: Triatoma sordida, Panstrongylus diasi, Panstrongylus megistus, Panstrongylus geniculatus and Rhodnius neglectus. Triatoma sordida represented 71.5% of all the triatomines captured, followed by Panstrongylus megistus (18%), Rhodnius neglectus (9.3%), Panstrongylus diasi (0.8%) and Panstrongylus geniculatus (0.4%). Of the total number of triatomines examined, 2.7% were positive for Trypanosoma cruzi. Panstrongylus megistus was the species that presented the highest rates of infection by Trypanosoma cruzi (8.3%), followed by Rhodnius neglectus (2.9%) and Triatoma sordida (1.4%). CONCLUSIONS: there is a need to adapt to new circumstances in epidemiology, with greater emphasis on entomological surveillance, since the potential for adaptation of secondary species of triatomines exists, especially where Chagas' disease is already under control.

“…In 1996, the Programa de Controle da Doença de Chagas (PCDCh -Chagas Disease Control Program) of the Fundação Nacional de Saúde/Ministério da Saúde (FNS/MSBrazilian Health Ministry National Health Foundation) collected 290576 triatomines in Brazil, the majority (69.2%) collected in the northeastern region of the country 13 . In recent years, northeastern Brazil has been affected by several actions impacting the environment, including native vegetation deforestation, mangrove destruction, desertification and the concentration of coastal estates that, together with certain economic activities such as cattle raising, citrus fruit cultivation, subsistence agriculture and livestock raising, destroy the environment in areas close to where low-income populations live 14 . The State of Sergipe has been on constant alert since the first reports of Chagas disease in the northeastern region in 1913, followed by serological surveys conducted in schoolchildren aged between 7 and 14 years in the 1970s and 1990s as well as the Health Ministry's publication of the Consenso Brasileiro em Doença de Chagas 15 , which aimed to guide control activities and classified the state as a highrisk area.…”

Introduction:The present study identified the triatomines collected in intra and peri-domestic environments, observed the occurrence of Trypanosoma cruzi infection in triatomines and correlated this information with housing conditions and the fauna associated with the rural areas of the City of Itabaianinha, located in the State of Sergipe, Brazil. Methods: Quarterly visits were conducted between March 2009 and March 2010, and the homes to be visited for the active search of insects were determined by random selection. In each housing unit, the insects were collected by a manual search with a metal clip and flashlight to inspect openings and cavities, with a collection time of one hour/home/individual. The Pirisa® dislodge chemical was used to force the insects to leave their ecotopes. Analysis of the intestinal contents of triatomines was performed in the laboratory to establish the presence of Trypanosomatidae. Results: Of the 103 dwellings surveyed, 17.5% were infested with Panstrongylus megistus. The village of Mutuca exhibited the highest infestation rate (38.1%). All the villages with relevant infestation rates were situated in the northern area of the city. The highest percentage of vector infection was found in the village of Água Boa (56.5%). The rural dwellings were found to be primarily brick or wooden house with or without roughcast or plastered walls, and the outbuilding most frequently associated with triatomines was the chicken run. Conclusions: These results emphasise the need for broader vector control and surveillance and for educational campaigns in the context of the Chagas Disease Control Program.
