Sussex University says clever wasps make trading partners
Wasps are like city slickers: Clever creatures make trading partners to help them compete for the best deal
Wasps have trading partners and compete for the best deals like city slickers according to new research.
Scientists say their findings show for the first-time that supply and demand theory can be used to understand helping behaviour in social insects.
They found 'helper wasps' raise the offspring of dominant breeders in small social groups in return for belonging in the nest.
Researchers from Sussex University's School of Life Sciences looked at how the economic rule of supply and demand applies to populations of paper wasps.
During the study, which was carried out in Spain, the researchers marked 1,500 wasps and recorded social behaviour within 43 separate nests along a cactus hedge over three months.
By increasing the number of nest spots and nesting partners available around the hedge, the researchers discovered the helper wasps provide less help to their own 'bosses' - the dominant breeders - when alternative nesting options are available.
The dominant wasps then compete to give the helper wasps the 'best deal', by allowing them to work less hard, to ensure they stay in their particular nest.
Traditionally scientists thought that factors within social groups, such as number of helpers and genetic relatedness, are what predominantly influences helping behaviour.
But the new findings, published in the journal Nature Communications, show that market forces in the whole population, such as the supply of outside options, can be used to predict insect behaviour.
Dr Lena Grinsted, of Sussex University, said: 'It is remarkable to discover that simply changing the wasps' surrounding social environment has a clear effect on cooperative behaviour within groups.
'Our findings reveal intriguing parallels between wasp populations and our own business world: a bad deal is better than no deal, so when competition increases so does the risk that you have to accept a lower price for what you offer.
'Market forces can clearly affect trade agreements in nature, as they can in human markets: with a larger number of trading partners available, you can negotiate better trade deals.'
Wasps have trading partners and compete for the 'best trade deals': study
Wasps have trading partners and compete for the 'best trade deals'—according to scientists from the University of Sussex.
In the study, the team from the University's School of Life Sciences, looked at how the economic rule of 'supply and demand' applies to populations of paper wasps—in which 'helper wasps' raise the offspring of dominant breeders in small social groups in return for belonging in the nest.
During the study, which was carried out in southern Spain over a period of three months, the team marked and genotyped 1500 wasps and recorded social behaviour within 43 separate nests along a cactus hedge.
By increasing the number of nest spots and nesting partners available around the hedge, the scientists discovered the helper wasps provide less help to their own 'bosses' (the dominant breeders) when alternative nesting options are available.
