Impact of the vector control program was evaluated eight years after implantation of epidemiological surveillance for Chagas disease in Berilo, a municipality in the Jequitinhonha Valley of the Brazilian State of Minas Gerais. In all 5,242 domiciliary units (96% of the total) were inspected and 10 found to be infested by the triatomine bug Triatoma pseudomaculata. Triatomines were found associated with bats inside one house and in the peridomiciles of the other nine. None of the 111 Triatoma pseudomaculata captured was infected with Trypanosoma cruzi. Noireau et al traps were installed in (n=8) and around (n=100) the infested house but no Trypanpsoma cruzi-infected triatomines were found. None bat, opossums (Didelphis albiventris) and rat captured in the peridomicile were infected with Trypanosoma cruzi although 24% of the inhabitants of the house infested by Triatoma pseudomaculata were seropositive for the parasite, based on ELISA, IHA and IIF.
在巴西米纳斯吉拉斯州热基蒂尼奥尼亚河谷的贝里洛市实施恰加斯病流行病学监测八年后，对病媒控制项目的影响进行了评估。共检查了5242个家庭住所（占总数的96%），发现10处有伪黄斑锥蝽这种锥蝽科昆虫出没。在一所房屋内以及其他九所房屋的住宅周边发现锥蝽与蝙蝠有关。捕获的111只伪黄斑锥蝽均未感染克氏锥虫。在受感染房屋内安装了8个诺罗陷阱，在其周边安装了100个，但未发现感染克氏锥虫的锥蝽。在住宅周边捕获的蝙蝠、负鼠（白腹袋鼬）和老鼠均未感染克氏锥虫，不过，基于酶联免疫吸附测定、间接血凝试验和间接免疫荧光法，受伪黄斑锥蝽感染房屋的居民中有24%对该寄生虫血清呈阳性。
