Brazil tests GM mosquitoes to fight dengue – SciDev.NetPosted: April 10, 2012
“From samples collected in the field, 85 per cent of the eggs were transgenic, which means that the males released are overriding the wild population. This [should result] in the decrease of Aedes mosquitoes, and in the decrease of dengue transmission,” he told SciDev.Net.
Malavasi is also the president of Moscamed — the Brazilian firm that produced the mosquitoes. The mosquitoes, which carry a gene which causes their offspring to die before reaching adulthood, were originally developed by the British firm Oxitec.
They have already been tested in Malaysia and the Cayman Islands, but this is believed to be the largest experiment in the wild to date.
“We developed technology to efficiently create the transgenic insects here [in Brazil], so we won’t need to buy them from England in the future, reducing costs,” Malavasi said.
