Africa Doesn’t Need Genetically Modified Mosquitoes


Some scientists have proposed genetically modified (GM) mosquitoes as a solution to controlling malaria, a scourge that has been around for centuries and is spread by mosquitoes.

I am skeptical that this is the answer.

Through CRISPR technology, a gene that prevents procreation is inserted in the lab and is passed on to mosquitoes in the wild. In essence, it rapidly transmits a sterilizing mutation through other members of the mosquito’s species, eventually wiping out the insects.

Creating GM mosquitoes is a contentious topic. Supporters of the technology consider it a huge step forward in the war against mosquitoes and by extension, vector-borne diseases like malaria, dengue, yellow fever and Zika. Critics of the idea, however, say it is dangerous to manipulate the DNA of any animal, and…
