The pheromones are essential chemicals produced in the exocrine glands for insect communication. The mandibular glands of eusocial bees produce pheromones with different functions according to the species, castes or takes developed by an individual of the same specie. On the cuticular surface of the bees there are surface pheromones to identify the individuals, castes or species, the understanding of the pheromone chemical composition and function mechanisms can contribute for the knowledge of the bases of the eusociability and of the cellular and chemical bases of the bee behavior. This study focus on the mandibular gland development and chemical composition in Melipona quadrifascita, comparing the results with the surface pheromones of bees with the same classes and stages.
