A test of worker policing theory in an advanced eusocial wasp, Vespula rufa.
Mutual policing is an important mechanism for maintaining social harmony in group-living organisms. In some ants, bees, and wasps, workers police male eggs laid by other workers in order to maintain the reproductive primacy of the queen. Kin selection theory predicts that multiple mating by the queen is one factor that can selectively favor worker policing. This is because when the queen is mat...
متن کاملWorker policing in the German wasp Vespula germanica
In some ants, bees, and wasps, workers kill or ‘‘police’’ male eggs laid by other workers in order to maintain the reproductive primacy of the queen. Kin selection theory predicts that multiple mating by the queen is one factor that can selectively favor worker policing. This is because when the queen is mated to multiple males, workers are more closely related to the queen’s sons than to the s...
متن کاملTemporal Polyethism and Worker Specialization in the Wasp, Vespula germanica
Temporal polyethism is a common mechanism of worker specialization observed in social insect species with large colony sizes, Vespula wasp colonies consist of thousands of monomorphic workers, yet studies based on small cohorts of workers report that temporal polyethism is either weak or completely absent in different Vespula species. Concerned that the small sample size of these studies preclu...
متن کاملRegulation of worker activity in a primitively eusocial wasp, Ropalidia marginata.
Rnpalidia marginata, a tropical, primitively eusocial, polistine wasp, is unusual in that the queen (the sole egg-layer) is neither the most behaviorally dominant nor the most active individual in the colony. The queen by herself rarely ever initiates interactions toward her nest mates or unloads returning foragers. There are always a few workers in the colony who are more dominant and acth"e t...
متن کاملEvolution of worker policing.
Workers in insect societies are sometimes observed to kill male eggs of other workers, a phenomenon known as worker policing. We perform a mathematical analysis of the evolutionary dynamics of policing. We investigate the selective forces behind policing for both dominant and recessive mutations for different numbers of matings of the queen. The traditional, relatedness-based argument suggests ...
