What Are GMO Mosquitoes and What Is Their Purpose?

A. Krosofsky,  GREENMATTERS,  2021.

Scientists have made GMO corn, strawberries, even many types of farm animals. Now, it seems, they have managed to genetically modify mosquitoes as well. But what is the purpose of GMO mosquitoes, and why would scientists go out of their way to create something that is already a problem for a huge portion of the planet’s population? As it turns out, GMO mosquitoes are a way to fight fire with fire. By creating and releasing their own genetically modified mosquitoes into existing populations, a few clever scientists have managed to curb the spread of dangerous mosquito-borne diseases like the Zika virus. According to the CDC, GMO mosquitoes are modified from the Aedes aegypti mosquito species. Aedes aegypti mosquitoes are commonly found in many parts of the U.S., including Florida and Texas. They are well known for spreading and carrying viruses like Zika, dengue, and chikungunya, but the GMO versions of these insects are designed to stop the spread of those diseases right at the source: the carriers themselves.
