Male mosquitoes don’t bite; they feed on flower nectar. Basically, male mosquitoes are harmless to humans. But female mosquitoes use blood to grow their eggs.
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。
nectar[ˈnektər]: n. 花蜜;甘露;神酒;任何美味的饮料
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%.
