ABSTRACT
Pheromones are chemicals produced as liquids by specialised cells or glands and transmitted into the environment as
liquids or gases. In contrary to hormones, which are excreted in organism and have effect exclusively on organism
that produced them, pheromones are excreted outside organism and effect on different individuals of the same species.
Pheromones mediate nearly all aspects of honeybee colony life including social defence, brood care, mating, orientation,
foraging and reproduction.
Pheromone investigation has high economic importance. With use of pheromones it is possible to manipulate with
pest insects on crops or to direct honeybees during pollination on target plants.
