In Britain, scientists at Oxford University and the biotech firm Oxitec have genetically modified (GM) the males of Aedes aegypti - a mosquito species that carries both the Zika virus and dengue fever. These GM males carry a gene that stops their offspring developing properly. This second generation of mosquitoes then die before they can reproduce and become carriers of disease themselves.
About three million of these modified mosquitoes were released on to a site on the Cayman Islands between 2009 and 2010. Oxitec reported a 96% reduction in mosquitoes compared with nearby areas. A trial currently taking place on a site in Brazil has reduced the numbers by 92%.
Whoa! That's heavy duty specicide!
