Brazil has opened the world’s largest mosquito factory to combat Dengue fever. That’s not a typo…it’s a mosquito factory, able to produce up to 190 million mosquitoes per week. The 1,300-square-meter factory breeds Aedes aegypti mosquitoes that are infected with Wolbachia bacteria, which prevents the Dengue virus from developing in their bodies and stops transmission to humans. When these mosquitoes reproduce, the bacteria is passed to their offspring.
The mosquitoes are raised in trays of temperature-controlled water, then moved to cages where males are fed sugary solutions on cotton balls and females are fed animal blood in bags that mimic human skin texture. They spend four weeks reproducing before being released. Brazil experienced its worst dengue outbreak in history in 2024, accounting for more than 80 percent of all reported infections worldwide. The factory can produce enough mosquitoes to serve a population of 100 million people for a year.
