Document Summary

Recruitment of foragers to food sources: the dance language. Dance to communicate distance, direction and food quality to potential foragers. Pass nectar (pollen) samples to other bees. Bees from observation hive trained to visit feeding station. Dancers and recruits are marked and observed. Scout bee finds a food source, fills her honey stomach and/or pollen baskets. Scout bee returns to the hive memorizing landmarks on the way back. Scout bee performs a specialized communication behavior on the vertical comb: a repeated pattern of body movements called dances . Karl von frisch described and interpreted honey bee dances, the most complex system of communication in insects. Experimental approach to study the dance language. The round dance, the wagtail dance, and the sickle dance. Language used by scout bees to recruit other bees to food sources; taste odor and dance. Depend mainly of the distance of the food source. Message: food at <80 m; close to the hive.
