Sterile mosquitoes are being released to collapse wild populations

The Aedes aegypti mosquito is often called the cockroach of the insect world because it follows human civilization wherever the climate allows. This invasive species, originally from Africa, is responsible for spreading debilitating diseases like dengue, Zika, and chikungunya to nearly 40 percent of the global population. To fight back, researchers at Google's Debug program and the World Mosquito Program are releasing millions of mosquitoes into the wild, but with a genetic catch that prevents them from ever having offspring.
