Malaria-Resistant Mosquitoes (GMOs)




Malaria-Resistant Mosquitoes


Each year, one million deaths are caused by malaria, and another 300 million people are infected—so it stands to reason that scientists should develop ways to end the fight against this disease. With the inspiration of fighting fire with fire, scientists have come up with malaria fighting mosquitoes. These types of mosquitoes have been genetically modified to develop resistance against the plasmodium parasite—making it near impossible to infect the host mosquito. But past experiences have shown that plasmodium parasites are able to quickly evolve and develop an immunity to anything that threatens to destroy them. So would it be better if scientists just killed all mosquitoes?
Funny you should mention that: a team of scientists have banded together to create a type of mosquito that are supposed to pass on a “sudden death” gene to their offspring, which will cause those baby mosquitoes to die of old age before they reach sexual maturity. However, the devastating ecological effect must be taken into consideration: if mosquitoes were eradicated, organisms like bats, which depend on mosquitoes for food would quickly face extinction as well.
