Inside the world's largest mosquito factory

According to Business Insider, the laboratory at the Center for Vector Control, jointly established by Sun Yat-sen University, China and the University of Michigan, USA, covers 3,500 square meters, including 4 workshops specializing in mosquito breeding.

This factory is full of mosquitoes.

The researchers' goal is to stop the next generation of Zika virus.

The lab raises millions of male mosquitoes for research.

In the lab, mosquitoes were injected with a strain of Wolbachia pipientis, a common bacteria that can block Zika virus and viruses that cause similar diseases like dengue fever.

After infecting the male mosquitoes, the researchers released them onto nearby islands to mate with wild females. The bacteria were passed on to the females, rendering their eggs unfertilizable.

Each factory produces 5 million mosquitoes a week.
