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.
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.
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%).
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.
从流行病学的角度来看，已知有超过 120 种的锥蝽（半翅目，锥蝽科）。2002 年 1 月至 2004 年 12 月，评估了来自米纳斯吉拉斯三角区和上帕拉纳伊巴的 16 个市的锥蝽中克氏锥虫的发生情况和阳性率。
主要按照国家卫生基金会的经典规范来捕获锥蝽。对锥蝽进行寄生虫学检查，采用卫生部描述的技术。在研究期间，共捕获了 990 只锥蝽标本，其中 771 只可进行检查。
共鉴定出 5 个物种：深色锥蝽、宽肩锥蝽、巨足锥蝽、斜纹锥蝽和林氏锥蝽。捕获的锥蝽中深色锥蝽占 71.5%，其次是巨足锥蝽（18%）、林氏锥蝽（9.3%）、宽肩锥蝽（0.8%）和斜纹锥蝽（0.4%）。在检查的锥蝽总数中，有 2.7%感染了克氏锥虫。巨足锥蝽的感染率最高（8.3%），其次是林氏锥蝽（2.9%）和深色锥蝽（1.4%）。
需要适应新的流行病学情况，更加重视昆虫学监测，因为二次物种的锥蝽具有适应的潜力，尤其是在已经控制了恰加斯病的地方。
