Nature crisis: Moths have 'secret role' as crucial pollinators 飛蛾作為傳粉者 扮演著重要的 “秘密角色”

Play audio file

新的研究顯示,飛蛾在夜間作為多種花卉及植物的傳粉者起著至關(guān)重要的作用。飛蛾的運(yùn)輸網(wǎng)絡(luò)比蜜蜂等日間傳粉的昆蟲更大、更復(fù)雜。

Long seen as fluttering pests that make holes in your clothes, scientists now say we have badly misjudged the humble moth. While bees are widely recognised for their role as pollinators, we have overlooked the same job being done by moths during the hours of darkness.

長久以來,飛蛾被看作是撲棱著翅膀、在衣服上鉆洞的害蟲,但現(xiàn)在科學(xué)家們說,我們嚴(yán)重地錯判了這些不起眼的飛蛾。雖然蜜蜂傳播花粉的作用被人們普遍認(rèn)可,但我們卻忽視了飛蛾在黑夜中也做著相同的工作。

The study published in the journal Biology Letters found that pollen often sticks to the moth’s hairy body and is then transported to a wide range of plants and flowers during their nighttime travels.

這篇發(fā)表在《生物學(xué)快報》期刊上的研究發(fā)現(xiàn),花粉通常粘在蛾子毛茸茸的身體上,等到夜間活動時,隨即被運(yùn)送到各種各樣的植物和花朵上。

Not only are their distribution networks larger and more complex than daytime pollinators, the moths help pollinate species rarely visited by bees and butterflies.

飛蛾的運(yùn)輸網(wǎng)絡(luò)不僅比日間傳粉昆蟲的網(wǎng)絡(luò)更大、更復(fù)雜,而且還能幫助蜜蜂和蝴蝶很少光顧的物種進(jìn)行授粉。

The researchers from University College London are concerned because moth numbers are still in serious decline due to pesticides and changes in land use. The moth’s real problem is perception, they say. And the key to preserving their vital role isn't regulation, but recognition.

來自倫敦大學(xué)學(xué)院的研究人員擔(dān)心,由于殺蟲劑和土地利用的變化,飛蛾數(shù)量仍在急劇下降。他們說,飛蛾面臨的真正問題是人們對這個物種的看法。然而保護(hù)飛蛾這一重要角色的關(guān)鍵不是規(guī)章制度,而是人們對它們的理解與認(rèn)可。
