The Galapagos Islands will release sterilized mosquitoes to fight dengue fever.

Ecuador will release 100,000 sterile Aedes aegypti mosquitoes into the Galapagos Islands. This will help reduce transmission of diseases such as dengue, Zika and Chikungunya. Researchers have been working on this solution for six years, which involves mass-growing Aedes aegypti in the lab and sterilizing them with radiation. The release of mosquitoes that are not able to fertilize females affects the population of the species, reducing it and therefore reducing the transmission of diseases.
