This survey aimed to assess the presence of triatomine vectors of Chagas disease within the rural communities of São João do Piauí, Northeast Brazil. Intradomiciliary and peridomiciliary collection strategies were implemented wherein 279 specimens of Triatoma brasiliensis macromelasoma, both nymph and adult were found in 15 (50%) of the studied homes. Of the intradomiciliary insects, 73 (67.6%) were identified as nymph instars (1st instar [N1]= 6, N2= 14, N3= 28, N4= 7 and N5= 18). In the studied communities, a continuous interaction between triatomine bugs and humans could be shown. It is therefore urgent that suitable strategies for the control of the triatomine vector are implemented in this area.
本次调查旨在评估巴西东北部皮奥伊州圣若昂多皮奥伊农村社区内恰加斯病锥蝽传播媒介的存在情况。实施了室内和室外采集策略，在15处（50%）被研究的房屋中发现了279只巴西大斑锥蝽标本，包括若虫和成虫。在室内昆虫中，73只（67.6%）被鉴定为若虫龄期（1龄[N1]=6只，2龄=14只，3龄=28只，4龄=7只，5龄=18只）。在被研究的社区中，可以证明锥蝽与人类之间存在持续的相互作用。因此，迫切需要在该地区实施合适的锥蝽传播媒介控制策略。
