Recycling decreases mosquito densities in Uruguay
A TDR-sponsored study in Uruguay has been published showing recycling significantly reduces the densities of mosquitoes and cuts in half the routine control costs. The research was conducted to identify measures to prevent outbreaks of dengue, which is transmitted by the Aedes aegypti mosquito.
Female mosquitoes lay their eggs in water tanks and other containers around the home, such as discarded flower pots and tyres. Once they become embryos, they can survive dry periods for up to a year, so it’s important to prevent this stage.
Uruguay was free of dengue until 1997, and since then its incidence has been increasing. It is surrounded by the endemic countries of Argentina and Brazil.
The study was the scale-up, second phase in Salto, Uruguay, and included strong community involvement to educate and promote recycling, which increased acceptance
The study authors cite the value of an interdisciplinary approach with the ministry of health and other government entities. They suggest this could be a model for other countries, particularly those affected by climate change that results in warmer temperatures which allows the aedes Aedes aegypti to thrive.
