提起蚊子的天敌,我们第一时间想到的是蚊香,但是现在科学家有了更好的办法:以蚊攻蚊,让带有基因缺陷的转基因蚊子去对付它的自然同伴,最后让蚊虫家族自行灭绝。这种转基因雄性蚊虫在交配后就会迅速死亡,还将把致命基因缺陷传给后代。饱受寨卡病毒和登革热困扰的巴西将成为第一个“放蚊子”的国家,在获得卫生机构许可后,一千万只转基因雄性蚊虫将被释放到拥有36万人口的皮拉西卡巴。 The mosquito genocide is beginning. Millions of genetically modified versions of the useless vampire insects are being prepared for release in Brazil. If all goes according to plan, the mosquitoes will have a huge sex party and begin to kill off all of their natural counterparts. 蚊虫大灭绝就要开始了。巴西正准备释放数百万转基因版本的无用吸血昆虫。如果一切按照计划来进行,那么这些蚊虫将举行巨大的性派对并开始杀死它们所有的自然同伴。 The world’s “first and biggest factory” for genetically modified mosquitos is in Piracicaba, Brazil. Its owner, Oxitec, is manufacturing male mosquitos that die quickly after they mate and pass on a genetic defect that causes any offspring to kick the bucket as well. In a country that has been hit hard by the Zika virus and dengue, this could be a game-changing, life-saving effort. |
