Mosquitoes created to help curb the spread of malaria

Scientists have created mosquitoes that produce 95% male offspring, with the aim of helping to control malaria.

The team at Imperial College London created genetically modified mosquitoes which only breed males, eradicating the malaria-carrying females.

Flooding cages of normal mosquitoes with the new strain caused a shortage of females and a population crash, the researchers said.

BBC London's Katharine Carpenter spoke to Dr Nikolai Windbichle and Prof Andrea Crisanti, both from Imperial College London, and Annemarie Meyer, from Malaria No More UK.
