  You can catch more flies with honey than withvinegar.

  比起用醋,你可能用蜂蜜会抓到更多的苍蝇。

  But if you want to kill them, you might try Truvia.

  但是如果你想置它们于死地,你可以试试Truvia。

  Because a new study shows that the activeingredient in this popular sweetener can act as aninsecticide.

  因为一项新的研究表明,这种流行的甜味剂中的有效成分可以用于杀虫。

  The study began as a sixth-grade science-fair project.

  这项研究最初是作为小学6年级的科学展项目。

  Eleven-year-old Simon Kaschock-Marenda noticed that his parents had stopped using sugar.

  11岁的西蒙卡西克马兰达注意到他的父母已经停止用糖。

  So he decided to see how different sweeteners affect the health of fruit flies.

  所以他决定研究不同甜味剂会对果蝇的健康产生多大影响。

  He and his dad, a card-carrying biologist, offered the flies food spiked with a variety of no-calsweeteners.

  他和他的生物学家父亲喂食果蝇各种无热量的甜味剂。

  Six days into the experiment all the Truvia-fed flies were dead, while those stuck with Sweet-n-low, Splenda or Equal lived five to seven weeks.

  经过6天的实验,Truvia 甜味剂造成果蝇全部死亡,而Sweet-n-low, Splenda 及Equal等甜味剂可以使得果蝇存活5-7周。

  Why Truvia makes flies drop like flies is still a mystery.

  为什么Truvia 甜味剂能使果蝇大量死亡,这仍然是一个迷。

  Back in the lab, the researchers confirmed that the bugs weren't starving: they all continuedto eat.

  回到实验室,研究人员证实这些苍蝇并不饥饿,却一直在吃。

  Most actually seemed to prefer Truvia to real sugar when offered a choice, findings published inthe journal PLOS One.

  在《公共科学图书馆综合》杂志发表的这项研究称比起真正的糖,果蝇实际上更喜欢Truvia 甜味剂。

  Next, the researchers will see if the sweetener kills other bugs, like cockroaches or ants.

  研究人员们接下来将继续研究这种甜味剂是否可以杀死像蟑螂,蚂蚁类的其他害虫。

  Until then, try tossing a little Truvia in your coffee, and on the counter.

  如果可以的话,到时候你只要在咖啡里或者柜子上放点甜味剂就可以了。
