Bees Rank Pollen by Taste

Walk through Time Times Square , - you’re bumbled bombarded with advertising. And it turns out, a bumblebee , might have a similar feeling, buzzing through a field of flowers. So these flowers , are these build balls of billboards, they’re advertising are good. It’s a good, this delicious nectar to the worldreward, and bees are very picky shoppers. Anne Leonard, a pollination biologist at the University of Nevada, Reno.

She describes the a flower field as a sort of pollination marketplace. And one way , bees choose where to visit.

? Bees are nectar experts. They are really good at assessing even really small differences , in like sugar concentration of nectar. They also scope out the shape and size of flowers and their color and scent. And now Leonard and her colleagues have discovered that bumblebees are pollen aficionados, too.

They found out that out by lacing batches of cherry pollen with either table sugar or bitter quinine. And they to display the pollen to bees. , we got really into it , - we set up a started 3-D printing flowers in our lab. And for the answer, anther - the male flower part, which presents the pollen - pipe cleaners. So we’ve we bought out Michael’s craft store’s store supplies of these pipe cleaners and used them in our experiments.

It Turns out that bees will would return again and again to the same colored color flower that dispenses dispensed sweet pollen, and spent spend more time collecting there. But when confronted with the bitter pollen? They sought a different color colored flower for the their very next stop. All of which suggest suggests that, in addition to savor in savoring nectar, bees taste pollen too - and judge flowers by it. The results are in the journal Biology Letters.

The finding means that plants have to find a happy medium. : So can you make your pollen attractive enough , that the bees will collect it, but distasteful stuff enough that they won’t collect too much of it. ? And that balancing act, of carefully collaborative calibrated chemistry is - it’s just one of the many transactions that plays out in a the buzzing pollination marketmarketplace. Well, Where the objective object is to make a sweet profit.
