Triatomine surveillance in rural areas, artificial ecotypes, and natural ecotopes of the cities of Caturama, Ibipitanga, Macaúbas, and Seabra in the south-central region of the Brazilian state of Bahia was carried out between 2008 and 2013. Natural infection by Trypanosoma cruzi was evaluated in the specimens collected to monitor vectors of Chagas disease. A total of 1,357 specimens were collected, and four species were identified: Triatoma sordida (83%), Triatoma lenti (16.4%), Triatoma pseudomaculata (0.5%), and Panstrongylus geniculatus (0.1%). Triatoma sordida was found in four cities, only 0.7% in intradomiciliary environments. Triatoma lenti was found only in Macaúbas; 8.5% were found in intradomiciliary environments, 88.3% in peridomiciliary environments, and 3.1% in sylvatic environments. Natural infection by T. cruzi was 0.5% for T. sordida and 3.1% T. lenti. All of these cases were found in peridomiciliary environments of Macaúbas. As the results show, triatomines were found in intradomiciliary environments in three cities that were surveyed in the south-central region of the state of Bahia. Thus, an epidemiologic survey should be performed to avoid the risk of transmission to the population.
2008年至2013年期间，在巴西巴伊亚州中南部地区的卡图拉马、伊比皮坦加、马考巴斯和塞阿布拉等城市的农村地区、人工生态型和自然生态环境中开展了锥蝽监测。对采集的标本进行了克氏锥虫自然感染情况评估，以监测恰加斯病的传播媒介。共采集了1357个标本，鉴定出4个物种：污色锥蝽（83%）、伦氏锥蝽（16.4%）、拟黄斑锥蝽（0.5%）和膝形长红猎蝽（0.1%）。污色锥蝽在4个城市均有发现，仅0.7%存在于室内环境。伦氏锥蝽仅在马考巴斯被发现；8.5%存在于室内环境，88.3%存在于室外环境，3.1%存在于野生环境。污色锥蝽的克氏锥虫自然感染率为0.5%，伦氏锥蝽为3.1%。所有这些感染病例均在马考巴斯的室外环境中发现。结果显示，在巴伊亚州中南部地区接受调查的3个城市的室内环境中发现了锥蝽。因此，应开展流行病学调查以避免向人群传播的风险。
