Brazilians welcome genetically-modified mosquito to help fight dengue fever
The Brazilian government has authorized the two-year trial. The hope is that the male GM mosquitos will mate with wild females and produce offspring that will die before they can reproduce .
Other countries are taking note. Field testing with the GM mosquitoes will begin in Panama this month and the US Food and Drug Administration is expected to decide soon on a possible test release of GM mosquitoes to fight dengue in the Florida Keys.
