        Alarm over decline in flying insects 飛蟲數(shù)量銳減值得警惕

        文字稿

        德國63個自然保護區(qū)內(nèi)的飛行類昆蟲數(shù)量在過去27年中減少了四分之三以上。研究人員認為這一現(xiàn)象值得警惕,因為飛蟲是自然生態(tài)系統(tǒng)中的重要組成部分。它既是植物的授粉者,也是扮演食物鏈的關(guān)鍵角色。請聽報道。

        Since 1989, scientists have been monitoring flying insect populations in 63 nature reserves across Germany. The decline of some species, like butterflies, has long been suspected but this research included lesser studied insects, like wasps, flies and moths. The drop in numbers of more than three quarters over 27 years turned out to be more severe than previously thought.

        The insects play a vital role in pollination and as a food source for birds. No one factor alone could explain their disappearance, but researchers said modern agriculture creates a hostile environment - a desert for insects.

        While, anecdotally, in recent years, drivers have reported fewer insects being squashed on their windscreens - another signal with the decline in bugs across all landscapes, experts said.
