Carpenter ants give one another slobbering kisses to change meals and vital proteins of their saliva.


Analysis has proven that carpenter ants give slobbering kisses to one another to change meals and vital proteins of their saliva.

  • Carpenter ants share meals and vital proteins after they kiss.
  • This ensures that every ant has what it wants to meet its function within the colony.
  • For instance, nurse ants that care for his or her younger have extra anti-aging proteins of their stomachs.


A brand new examine reveals that carpenter ants salivate and induce colony-wide metabolism by drooling “kisses” of one another.

Throughout a kiss, ants share each meals and vital proteins, based on scientists from the College of Friborg.

This change ensures that every ant has every thing it wants to meet its function within the colony, be it a gatherer, nurse, or queen.

The workforce hopes the findings will assist make clear how different creatures, together with people, distribute metabolic duties between completely different tissues or completely different cells of their physique.

What are carpenter ants?

Carpenter ants get their title from the development of their nest, through which they dig up wooden and kind easy tunnels in it.

Carpenter ants don’t eat wooden; they solely make tunnels and gnaw via wooden to create nests.

The mature western black carpenter ant colony numbers between 10 and 20,000 employees, and enormous colonies quantity over 50,000.

In the course of the examine, the researchers tried to know why ants change fluids via “kissing”.

“Particular person ants have two stomachs – one for digesting their very own meals and the opposite, which comes first, a ‘social abdomen’ for storing fluids that they share with different ants of their colony,” defined Adria Leboeuf, senior writer of the examine.

“These liquid exchanges permit the ants to share meals and different vital proteins that the ants make themselves.”

The researchers analyzed the proteins produced by the ants discovered within the social stomachs of particular person ants earlier than evaluating how the proteins modified with the ant’s function within the colony.

In addition they assessed whether or not the proteins modified relying on whether or not the ants had been a part of a brand new colony or extra established.

“To assist us perceive why ants share these fluids, we investigated whether or not the proteins they change are associated to the function of people within the colony or to the life cycle of the colony,” defined lead writer Sanja Hakala.

Their evaluation revealed completely different proteins relying on the function of the ant within the colony and the age of the colony.

The researchers analyzed the proteins produced by the ants found in the social stomachs of individual ants before comparing how the proteins changed with the ant's role in the colony.

The researchers analyzed the proteins produced by the ants discovered within the social stomachs of particular person ants earlier than evaluating how the proteins modified with the ant’s function within the colony.

For instance, ants in additional mature colonies had extra proteins related to the expansion and metamorphosis of their younger.

In the meantime, the nurse ants that cared for the younger had been discovered to have extra anti-aging proteins of their stomachs.

Total, this means that colony members might pool their life-extending proteins in nurses to supply take care of the subsequent era.

Ms Hakala mentioned, “These outcomes point out that some members of the colony can carry out metabolic work for the good thing about others.”

Whereas the researchers emphasize that extra work is required to know the function of every protein, they hope the findings will assist make clear how different creatures, together with people, distribute metabolic duties between completely different tissues or completely different cells of their physique.

Ms LeBeuf added: “It’s tough to measure how metabolic work is distributed between cells.

“That is the place the ants go issues on in such a means that we are able to simply entry what they’re sharing.

“A greater understanding of how ants share metabolic labor can assist us be taught extra about how different creatures, reminiscent of people, distribute metabolic duties between completely different tissues or completely different cells of their physique.”

HOW DO ANTS USE MATHEMATICALLY TO BUILD LIVE BRIDGES?

Some species of ants construct “dwelling bridges” from their our bodies to bridge small gaps.

In 2015, researchers on the New Jersey Institute of Know-how confirmed that as much as 20 p.c of the colony might be blocked by bridges alongside the route at any time.

That is when a person ant can run a “bridging” algorithm.

An ant can inform what number of instances it has been chased by earlier ants and use that to estimate the width of the bridge.

When this quantity reaches a sure quantity, the ant – judging that too many members of the colony can now occupy the bridges – can be part of the march.
