在大多数国家，控制恰加斯病的传播仍然以国内使用杀虫剂为基础。因此，我们评估了室内喷洒氟氯菊酯对控制墨西哥尤卡坦半岛唯一的恰加斯病媒介Triatoma dimidiata的效果，并在长达9个月的时间里，每15天监测一次潜在的再次侵害。我们发现，在施用杀虫剂4个月后，成虫再次侵入房屋，可能来自森林/围生区。这表明，需要考虑到森林/室内成虫可能扩散到住所的情况，以及为有效控制病媒而采取的连续性行动。
In most countries, Chagas disease transmission control remains based on domestic insecticide application. We thus evaluated the efficacy of intra-domicile cyfluthrin spraying for the control of Triatoma dimidiata, the only Chagas disease vector in the Yucatan peninsula, Mexico, and monitored potential re-infestation every 15 days for up to 9 months. We found that there was a re-infestation of houses by adult bugs starting 4 months after insecticide application, possibly from sylvatic/peridomicile areas. This points out the need to take into account the potential dispersal of sylvatic/peridomestic adult bugs into the domiciles as well as continuity action for an effective vector control.
