10 Second Trivia. Salt Marsh, Atlas and Indian Meal are all types of what? Vultures, moths, herbs or peat. These are all types of moths, insects that often fly by night.

10秒快速问答。盐沼,阿特拉斯和印度谷螟都是什么?是秃鹫,飞蛾,草本植物还是泥炭。这些都是蛾子的种类,通常在夜间飞行的昆虫。

Those are just three of the 160.000 species of moths and new research suggests they may play an important role in pollination. How do scientists know this? A few years ago in Norfolk, England, researchers swabbed more than 800 moths and then studied the pollen on them. It wasn't a direct study of pollination, the process that fertilizes plants and produces seeds, but instead a look at how pollen is transported.

这只是16万种蛾子中的三种,新的研究表明它们可能在授粉中扮演着重要的角色。科学家是怎么知道的呢?几年前,研究人员诺福克在英国采集了800多只蛾子,然后研究了它们身上的花粉。这并不是对授粉的直接研究(授粉是植物受精和产生种子的过程),只是研究了花粉是如何运输的。

That's an important early part of the pollination process. Scientists found that more than 45 percent of the moths they studied had visited dozens of different plant species during the night, including some that bees and butterflies didn't visit during the day.

这是授粉过程中重要的早期部分。科学家们发现,他们研究的飞蛾中,有超过45%的蛾子在夜间拜访过几十种不同的植物,其中一些是蜜蜂和蝴蝶在白天也没有拜访过的。

And researchers say this adds to the importance of conserving the insects because like bee populations, moth populations are decreasing worldwide.

研究人员说,这增加了保护昆虫的重要性,因为像蜜蜂,飞蛾的数量在全世界都在减少。

Scientists say to address that, people should reduce the use of pesticides when possible and make sure that moths have a food source and an undisturbed place to live. Their research was published in the "Journal Biology Letters".

科学家说,为了解决这个问题,人们应该尽可能减少使用杀虫剂,并确保飞蛾的食物来源、栖息地不受干扰。该研究发表在《生物学快报》杂志上。
