A new article focusing on the WIN network has been published in the scientific journal of IRD (Sciences au Sud). This article came after the presentation of the first results of the commissioned reviews during the WIN International workshop held in Rio de Janeiro from December 5 to 7, 2016.

[Abstract] After dengue fever and chikungunya, the Zika epidemic has put arboviruses back in the headlines, showing the importance of fighting their carrier mosquitoes (primarily Aedes Albopictus and Aedes Aegypti) more effectively. Meeting in Rio de Janeiro in December, at a workshop involving over 30 nationalities, experts from the WIN network warned that these two carrier insects are showing a growing number of resistances to the world’s most used insecticide families: pyrethroids and organophosphates. Map data from the University of Oxford, a member of the network, show the regions where resistance is most frequent to be Latin America, the Caribbean and Southeast Asia. The researchers are concerned that these areas are those with very high numbers of mosquitoes, and those with an upsurge of arbovirus epidemics, such as dengue fever in Thailand or Zika in Brazil. Arbovirus vectors are also active in other high-risk areas where there is a severe lack of resistance data. The researchers emphasise that in Africa, despite being heavily present, arbovirus vectors often come second in entomological studies which focus on the malaria-carrying Anopheles mosquitoes.
