LONDON: Scientists have succeeded in wiping out a population of caged mosquitoes in laboratory experiments using a type of genetic engineering known as a gene drive, which spread a modification blocking female reproduction.
The researchers, whose work was published on Monday in the journal Nature Biotechnology, managed to eliminate the population in less than 11 generations, suggesting the technique could in future be used to control the spread of malaria, a parasitic disease carried by Anopheles managed mosquitoes.
“It will still be at least five to 10 years before we consider testing any mosquitoes with gene drive in the wild, but now we have some encouraging proof that we’re on the right path,” said Andrea Crisanti, a professor at Imperial College London who co-led the work.
The technique used in this study was designed to target the specific mosquito species Anopheles gambiae that is responsible for malaria transmission in sub-Saharan Africa.
The disease infected around 216 million people worldwide in 2016 and killed 445,000 of them.
