Worker 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 کاملCognitive Plasticity in Foraging Vespula germanica Wasps
Vespula germanica (F.) (Hymenoptera: Vespidae) is a highly invasive social wasp that exhibits a rich behavioral repertoire in which learning and memory play a fundamental role in foraging. The learning abilities of these wasps were analyzed while relocating a food source and whether V. germanica foragers are capable of discriminating between different orientation patterns and generalizing their...
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 کاملSocial Learning in Vespula Germanica Wasps: Do They Use Collective Foraging Strategies?
Vespula germanica is a social wasp that has become established outside its native range in many regions of the world, becoming a major pest in the invaded areas. In the present work we analyze social communication processes used by V. germanica when exploiting un-depleted food sources. For this purpose, we investigated the arrival pattern of wasps at a protein bait and evaluated whether a forag...
متن کاملChemical Attractants for Trapping Yellow jackets Vespula germanica and Vespula pensylvanica (Hymenoptera: Vespidae)
Worker yellowjackets (Hymenoptera: Vespidae) were captured in traps baited with combinations of an aqueous solution of acetic acid and polyethylene caps loaded with either butyl butyrate, heptyl butyrate, or isobutanol. Vespula germanica (F.) were captured in large numbers in traps baited with acetic acid and isobutanol or acetic acid and butyl butyrate. Vespula pensylvanica (Saussure) were cap...
