Scientists have found a way of genetically modifying mosquitoes to produce sperm that only creates males, offering a potential fresh approach to fighting and eventually eradicating malaria.

Researchers from Imperial College London tested a genetic method that distorts the sex ratio of Anopheles gambiae mosquitoes, the main transmitters of the malaria parasite, so that the female mosquitoes that bite and pass the disease to humans are no longer produced.

In a study published in the journal Nature Communications, the team reported that in the first laboratory tests, the technique created a fully fertile mosquito strain that produced 95 percent male offspring.
