Gene editing wipes out mosquitoes in the lab

• https://www.bbc.com

The team tested their technique on the mosquito Anopheles gambiae, which transmits malaria.

They altered part of a gene called doublesex, which determines whether an individual mosquito develops as a male or as a female.

This allowed the Imperial College London scientists to block reproduction in the female mosquitoes.

They want to see if the technology could one day be used to control mosquito populations in the wild.

Writing in the journal Nature Biotechnology, Prof Andrea Crisanti and colleagues report that caged populations of Anopheles gambiae collapsed within 7-11 generations.

Dr Crisanti said: "2016 marked the first time in over two decades that malaria cases did not fall year-on-year despite huge efforts and resources, suggesting we need more tools in the fight."
