The move is aimed at reducing the local mosquito population, which could pass the Zika virus to humans, said Xi Zhi-yong, who heads the study.
Xi is a microbiology professor at Sun Yat-sen University in Guangzhou, Guangdong province.
Millions of laboratory-produced Aedes aegypti mosquitoes infected with the Wolbachia bacteria will be released at two or three trial sites in Guangdong.
Last year, the team lowered the mosquito population by 90 percent during a trial using the same method and helped to contain a local outbreak of dengue fever. Both dengue and Zika are viruses spread by the Aedes aegypti mosquito.
Xi said the researchers only release male mosquitoes, which don’t bite. The eggs produced by females mating with Wolbachia-infected males are infertile, which leads to reduced mosquito populations.
The Zika virus, which has been linked to severe birth defects in thousands of babies in Brazil, is spreading rapidly in the Americas.
The US has reported a sexually transmitted Zika case, but the World Health Organization has said more investigations are needed to verify this.
No Zika cases have been reported in China to date. On Thursday, the National Health and Family Planning Commission ordered the mass extermination of mosquitoes.
Xi said the team is working on ways to produce more Wolbachia-infected mosquitoes and is considering drones to help release them in March.
The WHO has recommended studies of genetically engineered mosquitoes and those infected with bacteria to help with reduction efforts.
Xi said the genes of Wolbachia-infected mosquitoes are intact and the mosquitoes are safer for the ecological environment and other species, including humans.
But he said more field studies are needed to evaluate this method before it is used in other parts of China to control and prevent the Zika virus.
Guo Yuhong, a researcher at the Chinese Center for Disease Control and Prevention’s Infectious Disease Institute, said Aedes aegypti mosquitoes can be found widely in South China and some northern areas of the country.
But she remains cautious about the Wolbachia-infected mosquitoes and feels that more investigations are required.
“They work in theory, but we are not sure about the potential impact that extinction of Aedes aegypti mosquitoes would have on the ecosystem,” she said.8.03KRelated ArticlesUS confirms first sexually transmitted Zika caseZika curbs to include mosquito mass exterminationHonduras declares national emergency over Zika virusMainland Chile confirms first 3 cases of Zika virusWHO declares Zika virus extraordinary emergencyTagsmosquitoe Zika healthPhotoWang Ou graces fashion magazineHsu Chi and Huang Bo pose for CosmopolitanAdorable little monks go viral onlineFormer Olympic champion poses with familyActress Yao Chen releases reunion photosZhang Liang poses for mens uno magazineArtFilmCelebrityFashionFoodTravelMonkey on stampsArt exhibitions in 2016 worth seeingTalented artist makes tiny pencil lead sculpturesChina eases restrictions art imports, exportsPeking Opera finds a colorful new canvasLao Shu: I am true to my everyday anxietiesLao Shus art speaks a new languageArtworks of monkey figures exhibited in BeijingAwards celebrate emerging Asian artists take on issuesWoodprint pictures making a comebackSwiss collector to display Chinese artChinese embroidery exhibition returns to the LouvreMonkey King cartoons through the yearsSequel breaks nine records on opening weekendInsider: China to surpass US to be top film market in two yearsHollywood blockbusters dubbed in Mandarin drawing more viewersChinas Spring Festival Gala video shown at Times SquareThe Assassin tops nomination at 10th Asian Film AwardsStephen Chow gives away nothing-as usualMan from Macau III rolling the diceHigh expectations for Crouching Tiger sequelCrouching Tiger Hidden Dragon II holds world premiere in BeijingUS Route 66 part of new Chinese films scenerySpring Festival Gala to feature Sa DingdingFormer Olympic champion poses with familyChinas Yao honored with Crystal Award in DavosWang Ou graces fashion magazineHsu Chi and Huang Bo pose for CosmopolitanActress Yao Chen releases reunion photosZhang Liang poses for mens uno magazineSharing their wealth: Chinese celebrities and charityActress Li Xiaolu releases bridal fashion shotsSun Li poses for LOfficiel Hommes magazineZhang Ziyi reveals daughters baby name on WeiboGuo Pei Spring/Summer 2016 show at Paris Fashion WeekVancouver student wins Miss Chinese Intl 2016Chanel Haute Couture Spring/Summer 2016 collectionDonatella Versace Haute Couture Fall/Winter 2016/17Wang Ou graces fashion magazineActress Liu Yifei poses in ParisDesigners target worlds richest womenFashion briefs Buying into a new ideaGuo Pei Spring/Summer 2016 show at Paris Fashion WeekGiorgio Armani Prive Haute Couture Spring/Summer 2016 collectionDior Haute Couture Spring/Summer 2016 collectionLiu Yifei attends fashion show in ParisVivienne Westwood Spring/Summer collection posters releasedIn pics: 1985 edition of A Bite of ChinaTastes of the seaTraditional food Kasai ready for Tibetan New YearEat beatFair-trade afternoon teaFine Danish dining in Chinas capitalFad or future?
