Pheromones

Pheromones are chemicals that humans, animals and insects use to communicate. Pheromones are analogous to an excreted/secreted hormone.  Read more on pheromones on the Wikipedia page.

Pheromones are involved in almost every aspect of the honeybee colony life: development and reproduction (including queen mating and swarming), foraging, defense, orientation, and in general the whole integration of colony activities, from foundation to decline.
