Moscamed releases GM anti-dengue mosquitoes
The Moscamed Commission has launched genetically modified sterile male mosquitoes, developed by UK pest control company Oxitec, genetically modified sterile male mosquitoes for the control of dengue mosquitoes (Aedes aegypti) in urban areas of Brazil. Mosquitoes are being released in the town of Jacobina, Bahia state. The 48,000 population city registered 72 cases of dengue fever in the first three months of this year. "The most recent" trials of the Oxitec mosquitoes showed mosquito levels to have fallen by 96% within six months, a reduction maintained for "many months" even through the annual peak mosquito levels. The Commission opened a facility for raising such male mosquitoes last year (Agrow No 644, p 6).
