Strategies for controlling Chagas disease are based on spraying infested houses with pyrethroid insecticides. However, the intense use of these insecticides has promoted resistance of Triatoma infestans and, in Argentina, Bolivia and Southern Brazil, low levels of resistance have been reported. Due to the persistence of T. infestans in the state of Rio Grande do Sul (RS), we evaluated the occurrence of deltamethrin resistance in four strains from different municipalities in comparison to two susceptible strains from Brazil and one resistant strain from Bolivia. The results indicated the absence of resistance in T. infestansfrom RS.
控制恰加斯病的策略基于用拟除虫菊酯杀虫剂喷洒受感染的房屋。然而，这些杀虫剂的大量使用促进了三带喙库蚊的抗药性，在阿根廷、玻利维亚和巴西南部，已经报道了低水平的抗药性。由于三带喙库蚊在南里奥格兰德州（RS）的持续存在，我们评估了来自 RS 不同城市的四个品系与来自巴西的两个敏感品系和来自玻利维亚的一个抗性品系相比，对溴氰菊酯的抗性情况。结果表明，来自 RS 的三带喙库蚊没有抗药性。
