What's important is that these male mosquitoes contain a self-limiting gene that gets passed onto female mates.

重要的是，这些雄蚊有一种自限基因，交配时能够传播到雌蚊体内。

When the females give birth, their offspring will die before adulthood thanks to the gene.

雌蚊产卵时，她们的后代将会因为携带这种基因而夭折。

Mosquitoes only start biting people once they're adults, so given enough time, the danger of blood-sucking female mosquitoes could be eradicated.

蚊子只会在成年之后叮咬人类，只要时间足够，来自吸血雌蚊的危险就可以根除。

This means it would be possible to stem the spread of malaria through mosquito bites.

这就意味着人类有可能通过阻断蚊虫叮咬控制疟疾传播。

英国公司Oxitec负责培育这些雄蚊，该公司称之为“友好蚊”，不过，雌蚊们可能不这么想。
