| Abstract: | It is known that there is a genetic basis to the labelling of individuals for kin recognition in the honey bee, Apis mellifera. This study shows that individual workers reared in total isolation are able to discriminate between their full sisters and maternal half sisters. When individuals were reared with a half sister, recognition of their own patritype persisted, together with a comparable awareness of the patritype of their half sisters. Workers, when reared in mixed patritype groups of 10, showed no tendency to discriminate between full and half sisters, i.e. they appeared to learn both nestmate patritypes equally well. However, the labelling phenotypes of individuals reared together became more uniform, possibly through the transfer of substances during trophallaxis and mutual grooming. Workers exposed to 10 patritypes from their full sister patriline were more likely to accept an unfamiliar full sister than workers exposed to only five. Finally, workers reared in the hive appeared to retain an ability to discriminate their own patritype; i.e., even though the hive consisted of two worker patritypes, they discriminated between unfamiliar full and half sisters that had been reared under the same controlled conditions in an incubator. |
