- Abstract: The social behavior of ants is controlled by means of the dynamic interactions between the environment and the individuals, mainly through the pheromones. Among the exocrine gland is the hypopharyngeal gland (HG), located laterally over the pharyngeal plate. Few works concerning the HG in ants, and these have focused mainly on the relationship between glandular development and the division of labor. Therefore, the present work aimed to describe and compare the HG in the different castes of the leaf-cutting ant Atta sexdens rubropilosa. The ants collected in the field were dissected in fixative solution in order to extract the HG, which was then submitted to routine procedures for histological, histochemical, and electron microscopy. The HG of different castes showed similar morphology varying only in relation to the secretory cell number. The secretory intracellular reservoir presented positive reaction to Xylidine Ponceau and P.A.S, indicating the presence of protein and polysaccharides in the secretion. These structures were stained by phalloidin-FITC and analyzed under confocal microscopy. 3D reconstructions were performed to understand the HG morphological organization. Therefore, we suggest that the function of this gland would be the production of digestive enzymes and/or some sort of mucus, which, together with the secretions produced by the salivary glands of the thorax, would be related to the production of saliva
