World of insects is very amazing. Sometimes it seems that their societies are very much organised like our own and that they do same things. They just do it in different way than how we, humans do it. Most recent studies have shown that they are not that allowing themselves to fully depend on current availability of food in nature. Rather, they force flowers to blossom! They have few tricks up their “sleaves” too. These studies explain how bumblebees force flowers to blossom.
Previous work has shown that various kinds of stress can induce plants to flower, but the role of bee-inflicted damage in accelerating flower production was unexpected.
According to a report in Science:
The researchers at ETH Zürich chanced upon the discovery when they noticed curious bite marks on leaves while studying how bees respond to plant odors. They had added bumble bees to a research greenhouse and observed them cutting holes in the shape of half-moons. What was going on? At first, the researchers thought the insects might be feeding on fluid from the leaves, but the bees didn’t stay long enough to get much. Nor did they appear to be taking any part of the leaves back to their colonies.
Bumblebees Force Flowers To Blossom
These studies were conducted outside as well as inside the laboratory. Bumblebees make these bites on leaves when there is not enough of pollen in nature. Observers have found thst bumblebees make tinny bites on leaves in shspe of half-moons.
Less there is pollen in nature, more often bumbleebees do it! And without doubt it has its effect! Tomato plant who had this damage on it’s leaves blossoms up to 30 days earlier! On the other hand, mustard plants will blossom up to 14 days earlier. We knew before that bumblebees are tomato pollinators but we did not know they force tomato to blossom too!
Considering climate change and lack of food due to ever-changing weather conditions i hope thst this technique by which bumblebees force flower to blossom will provide enough food for them. Wish you best little guys, honeybees have use from it too!
