Queen Bee Pheromones Guide Daughters' Nest Choices
A study published in the Proceedings of the Royal Society B reveals that queen sweat bees use pheromones to communicate with their daughters regarding the benefits of staying in the nest. The research highlights how chemical signaling plays a crucial role in the evolution of social cooperation.
Why it matters
This research contributes to the broader understanding of how social hierarchies and cooperative behaviors are maintained through chemical communication in the animal kingdom.
Female sweat bees need to make a pivotal life decision: remain in the nest to help their mother raise more offspring or leave to establish nests of their own. New research from the Smithsonian Tropical Research Institute (STRI) found that queen pheromones help influence that choice, offering new insight into how cooperation evolved in insect societies. In a study published July 28 in the Proceedings of the Royal Society B , STRI and Princeton University postdoctoral fellow Callum Kingwell, STRI staff scientist Bill Wcislo and colleagues identified for the first time that via pheromones, sweat bee queens of the species Megalopta genalis communicate to their daughters that sticking by them is a worthwhile investment.
