Have you ever been stung by a bee, then another one shows up, soon thereās a couple more, and before you know it, youāre doing your best ninja impersonation!?
I believe most of us have had a moment like this. I mean, it doesnāt matter whether youāre on a picnic, trying to enjoy your garden, or youāre a beekeeper that got yourself in the situation, Iām sure we can all agree, itās no fun.
So, how do bees know who & when to attack? After some research, I found you a quick & easy answer, Alarm Pheromones, but what are they.
What are Alarm Pheromones?
Merriam-Webster defines pheromones as: a chemical substance that is usually produced by an animal and serves especially as a stimulus to other individuals of the same species for one or more behavioral responses.
The alarm pheromones in honeybees are mainly produced in workers by the Koschevnikov gland which is located near the sting shaft. These pheromones are especially important to the colony, since the guard bees at the entrance are constantly inspecting everything that comes near the entrance, making certain only the bees that belong there enter, and kicking anyone else out.
When danger is spotted, guard bees appear at the hive entrance, raising their abdomen and exposing the sting chamber to release the alarm pheromones; they do this, all while they fan their wings. This then raises the alarm to the rest of the colony, and more reinforcements will arrive to help with the intruder.
The alarm pheromone make-up is quite complex, over 40 compounds (including precursor, intermediate, and final biosynthetic products) have been identified from extracts of the worker sting apparatus, among which about 15 components stimulate one or more alarm behaviors.
Did you know?
+ Bananas mimic the attack pheromone
+ This is due to a chemical produced by both ripening fruit & honeybees called Isoamyl acetate
+ So, if youāre a beekeeper, itās probably best not to eat a banana before checking hives
here are a few tricks, so...
