GUANGZHOU, CHINA - JUNE 20: Chinese Phd student and researcher Zhang Dongjing displays a container of sterile adult male mosquitos that are ready to be released in a lab in the Mass Production Facility at the Sun Yat-Sen University-Michigan University Joint Center of Vector Control for Tropical Disease on June 20, 2016 in Guangzhou, China. Considered the world's largest mosquito factory, the laboratory raises millions of male mosquitos for research that could prove key to the race to prevent the spread of Zika virus. The lab's mosquitos are infected with a strain of Wolbachia pipientis, a common bacterium shown to inhibit Zika and related viruses including dengue fever.??Researchers release the infected mosquitos at nearby Shazai island to mate with wild females who then inherit the Wolbachia bacterium which prevents the proper fertilization of her eggs. The results so far are hopeful:?? After a year of research and field trials on the island, the lab claims there is 99% suppression of the population of Aedes albopictus or Asia tiger mosquito, the type known to carry Zika virus. Researchers believe if their method proves successful, it could be applied on a wider scale to eradicate virus-carrying mosquitos in Zika-affected areas around the world. ??The project is an international non-profit collaboration lead by Professor Xi Zhiyong, director of the Sun Yat-Sen University-Michigan University Joint Center of Vector Control for Tropical Disease with support from various levels of Chinas government and other organizations.??
