"This is scientific american sixty seconds science. I'm schafer's on every honeybee colony has its own unique. Sent like a fingerprint and bees. Use that sent to recognize their nest. Mates basically saying you smell like me. So i'm gonna let you into the colony but here's the mystery if you transfer a baby into a new hive not only does the colony accept it but that be will eventually smell like. It's adopted ness mates. Even though they're not genetically related this kind of got us thinking perhaps not actually the genetics of the be. It's actually the genetics of the microbes. That live within the be cassandra. Verner is a postdoctoral researcher. At the university of illinois she knew gut microbes could affect the senate and communication of other animals like hyenas so she and her co authors designed a series of experiments to test whether microbes also change the sent compounds coating the outside of honeybees known as q titular hydrocarbons. In one experiment they had different gut microbes to newly hatched sister bees. The bees develop distinct microbiomes and the also produced different killer. Hydrocarbons sense but on the other hand if they were treated with different inoculations they recognize each other as not in that's mates or intruders and they attacked each other. Usually in the form of fighting each other in other words. Bees from the same colony did not recognize each other when they had different got abs. Washington university biology professor and co author. Yehuda says the microbes are changing the bees physiologically and controlling their complicated social behaviors. But he adds. This relationship is mutually beneficial for the bacteria and the bees the bees the pain of these. They have to have some of these syria. So the idea is that you have a system where this relationship serves the biology of both syria and the host and gets to the point where it's obligatory being able to distinguish nest. Mates from invaders is absolutely critical. Bench says without that ability bees would be vulnerable to nest parasites into other bees looking to steal their most precious commodity. Honey and so the entrance fee must be paid not dollars but incense for scientific americans sixty seconds science. I'm sheila farce.
