Is it wrong to release modified mosquitoes into the wild? Supporters say genetically altered insects could eradicate deadly diseases, but opponents are warning of dangerous consequences.
Synthetic biology may offer the knock-out blow. This branch of genetic engineering allows scientists to edit the mosquito’s DNA and introduce a “self-limiting” gene. This artificial DNA sequence kills the biting females whilst leaving the modified males to spread the auto-destruct gene through the wild population.
Authorities have approved the scheme in Florida but environmental groups are furious, calling it a “Jurassic Park experiment” that will unleash a “mutant bug” into the ecosystem. Many argue that the modified mosquito may have unforeseen consequences, and an online petition against the plan already has 240,000 signatures.
