Engineered males might mean fewer female Aedes aegypti mosquitoes to spread Dengue fever.

Scientists in Brazil say an experiment to reduce populations of the dengue-carrying Aedes aegypti mosquito, by releasing millions of genetically modified (GM) insects into the wild, is working.
More than ten million modified male mosquitoes were released in the city of Juazeiro, a city of 288,000 people, over a period of time starting a year ago.
The results were released at a workshop in Rio last week (28–29 March), where the project’s co-ordinator, Aldo Malavasi, said they were “very positive”.
