雄蚊不会咬人,它们以花蜜为食。基本上,雄蚊对人类是无害的。但雌蚊靠吸血来育卵。

Oxitec created a male mosquito with a special gene that prevents female offspring from surviving to adulthood. The new males grow up, mate with more females and over time the number of Aedes Aegypti declines.
Oxitec公司造出一种拥有特别基因的雄蚊,可以防止雌性后代存活到成年。新的雄蚊会长大,和更多雌蚊交配,随着时间过去,埃及伊蚊的数量就会减少。
In Brazil, which suffered a Zika outbreak in 2017 and 2016, the company claims its “friendly” mosquitoes reduced the population of Aedes Aegypti by 89% to 96%.
巴西在2017年至2016年曾暴发寨卡病毒,该公司声称它们的“友好”蚊子将巴西的埃及伊蚊的数量减少了89%到96%。
Is there opposition to these genetically modified mosquitoes?
这种转基因蚊子有没有遭到过反对?
Yes.
有的。
Oxitec has been trying to make Florida the first US test site for its “friendly” mosquitoes for nearly a decade.
近十年来,Oxitec公司一直试图让佛罗里达州成为美国首个测试“友好”蚊子的试验区。
The company came close in 2016, but local officials in Monroe County (the Florida Keys) ultimately voted no. Oxitec pulled its request and decided to try again with what it described as an upgraded version of the mosquito. That’s what the EPA approved May 1.
