Genetic Component of Bee Odor in Kin Recognition
1 Department of Entomology, University of Kansas, Lawrence 66045
The primitively social sweat bee, Lasioglossum zephyrum, blocks the entry into its nest of most conspecifics from other colonies. Laboratory inbreeding of these bees produced lines which showed a positive linear relationship between the coefficient of relationship of bees tested and how often they permitted non-nestmates to pass them. The most probable mechanism is a genetically determined odor coupled with a learned component by which guard bees discriminate between odors of close kin and other bees. Revised on July 24, 1979
