The World's Largest Mosquito Factory

In Guangzhou, China, millions of mosquitoes are born at the  Sun Yat-Sen University-Michigan University Joint Center of Vector Control for Tropical Disease in the hopes of finding a way to fight Zika. The lab's mosquitos are infected with a strain of Wolbachia pipientis, a bacterium that inhibits Zika and and other viruses by preventing the fertilization of eggs. Researchers at the center release infected mosquitos on Shazai island to mate with wild females, stopping the next generation. The lab claims there is 99% suppression of the population of Aedes albopictus or Asia tiger mosquito, the type known to carry Zika virus, after the first year of tests. [27 photos total]
