Genetically modified mosquitoes could soon be released into the wild in an attempt to combat malaria. Scientists at Imperial College London, who created the GM insects, say they could wipe out natural mosquito populations and save thousands of lives in malaria-stricken regions.
Led by Andrea Crisanti, the team added a gene that makes the testicles of the male mosquitoes fluorescent, allowing the scientists to distinguish and easily separate them from females. The plan is to breed, sterilise and release millions of these male insects so they mate with wild females but produce no offspring, eradicating insects in the target region within weeks. |
