Honeybees are a subset of bees in the genus Apis, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests out of wax. In this book, the authors present current research in the study of the foraging behaviour, reproductive biology and diseases relating to honeybees. Topics discussed include research into diseases affecting honeybees; the status of bee health and colony losses in Argentina; situational choices among alternative visual stimuli in honeybees and paper wasps when foraging; regulation of the crop content for foragers upon departing the hive; sex differences of dopamine control systems associated with reproduction in honeybees; and the roundtrip-structure of the foraging honeybee (Apis mellifera).
