Abstract

The "South American Research Network for the Surveillance and Control of Insecticide-Resistance in Arthropod Vectors" (WINSA), established in 2024 by the IRD and FIOCRUZ with support from the US-CDC VecNet initiative and WHO-TDR, aims to coordinate research on insecticide resistance in arthropod vectors in South America, provide a platform for regional collaboration, and develop effective mitigation strategies. WINSA brings together leading technical experts representing research institutions from 14 countries and territories located in South America, the USA, and France to promote collaboration and information exchange, identify research gaps and priorities, enhance technical capacity in insecticide resistance monitoring, and support national and regional programs on vector resistance issues. This network seeks to contribute to the reduction and elimination of vector-borne diseases in South America.

This represents data across all insecticides (pyrethoids, carbamates, and organophosphates) and all types of adult bioassays (CDC bottle assays and WHO filter paper tube test). The green dots indicate susceptibility (≥98% mortality), the yellow dots indicate possible resistance (mortality >90% and <98%), and the red dots indicate resistance (<90%), according to WHO guidelines [22].
