Singapore is intensifying its battle against dengue fever by breeding millions of male mosquitoes for release into the wild. The initiative, overseen by the National Environment Agency, employs the sterile insect technique: sterilized males mate with wild females, producing no offspring and thereby reducing the population of Aedes mosquitoes that transmit the virus. This approach offers a sustainable alternative to chemical insecticides and is part of Singapore’s broader strategy to control mosquito‑borne diseases.
