Science – The next time you bite into a bright red, perfectly shaped strawberry, give a shout-out to the bees. A new study shows that pollination by the insects increases the quality and shelf life of strawberries, saving hundreds of millions of dollars in the process. Bees could be providing the same benefits for a variety of other fruits and vegetables as well.
It’s well known that pollination increases the yield of most crops. Seeds, nuts, fruit, and grain can be larger and more plentiful when insects or other animals transfer pollen between plants, in contrast to when plants pollinate themselves, a process called selfing. But quality turns out to be important, too. Teja Tscharntke, an agroecologist at the University of Göttingen in Germany, got the idea to study quality about a decade ago, while he was investigating pollination of coffee plants in Indonesia. He and his student Alexandra Klein noticed that not only was coffee yield higher with more bee species, but malformations such as unevenly shaped beans were also reduced.
