LONDON (Reuters) – 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.
“For the very first time, we have been able to inhibit the production of female offspring in the laboratory and this provides a new means to eliminate the disease,” said Andrea Crisanti, who led the research at Imperial’s department of life sciences.
Nikolai Windbichler, who co-led the work, said what was most promising about the results is that they are self-sustaining.
“Once modified mosquitoes are introduced, males will start to produce mainly sons, and their sons will do the same, so essentially the mosquitoes carry out the work for us,” he said.
