Porto Alegre, 30 April 1991 Working with stingless bees I am interested in their swarming behavior and especially in COHESION OF BEES IN A SWARM. How do bees get to a distant target as a whole group? From Apis it is said that the Nasanov gland substances are involved. Anybody who can suggest some papers or personal experiences?
