“…In the wild environment P. geniculatus inhabits, preferentially, armadillo burrows (Dasypus spp.) 26,27 , but it has been found in the domiciliary environment in different states of Brazil 18,[54][55] .Punctual distributions of P. diasi in DF were also observed. This species is distributed in areas of cerrado in central Brazil 18,56 and has been found in the domiciliary environment without description of wild ecotopes 26 .…”

This retrospective analysis considered the number of adults and nymphs of each species collected and infected in both intradomicile and peridomicile. Results: A total of 754 triatomines were collected in 252 reported domiciles. Panstrongylus megistus was the most frequent species (65%), followed by T. pseudomaculata (14%). Of the 309 examined insects, only 3 (1%) specimens of P. megistus were infected with flagellates morphologically similar to Trypanosoma cruzi. The spatial occurrence indicated a higher diversity of triatomines and frequency of T. sordida in rural areas. Moreover, there was a predominance of P. megistus in urban areas. The number of records of P. megistus in the rainy season was two times higher than that during the dry season. The largest number of triatomines was collected in November. Conclusions: The presence of P. megistus specimens infected with trypanosomes in domiciles, shows the potential risk of human infection in DF. Thus, it is essential to continue entomological surveillance, intensifying it in the rainy season and in regions of greater occurrence. Keywords: Chagas disease control. Entomological surveillance. Synanthropic triatomines. Federal District. Brazil. triatomines. Furthermore, the invasion and/or colonization of infected triatomines from wild ecotopes may represent the risk of vectorial transmission with the installation of peridomiciliary and domiciliary cycles of T. cruzi 6,7 . In this context, the objective of this paper is to analyze the spatial and temporal occurrence of triatomine species collected in DF, as well as their indices of natural infection with trypanosomes to direct actions of entomological surveillance of Chagas disease coordinated by SES-DF. RESUMO 72 METHODS RESULTS Maeda MH et al -Occurrence of triatomines in DF Study areaThe Federal District of Brazil is geographically located between the parallels 15º30' and 16º03' south latitude, and between meridians 47°25' and 48°12' west longitude, in Central Brazil, one of the highest areas of the region, the Central Plateau. According to 2010 Census results, the population comprises 2,563,963 people in an area of 5,787,784km 2 divided into 30 administrative regions 8 . The area is filled with plateaus over 1,000m in altitude. The average annual rainfall is around 1,600mm, and the average annual temperature ranges between 18°C and 20°C with two distinct seasons, the dry season from May to September and the rainy season from October to April, the latter season with the highest temperature records 9 . Triatomine collection and natural infectionThe insects were collected in intradomiciliary and peridomiciliary environments by residents and then taken to the PITs. Each PIT receives a kit with materials for insect storage, a notepad to keep notes containing the address and location of collection, and tweezers for the handling of specimens.After notification, the SES-DF public health agents did active searches in these houses and their annexes. The materials used for triatomine collection were metal tweezers and fl...

“…Some, such as P. megistus, are important vectors of Chagas disease due to their close association with humans. Others, such as P. chinai, P. geniculatus, P. herreri and P. rufotuberculatus are considered secondary vectors because of their increasing ability to invade and colonise domestic habitats (Lent and Wygodzinsky, 1979;Calderón et al, 1985;Noireau et al, 1994;Valente, 1999;Carcavallo et al, 1999;Wolff and Castillo, 2000;Abad-Franch et al, 2001).…”
