The mandibular glands of hymenopterans in general are paired structures located on eachside of the head. These glands possess an excretory duct located at the internal surface of the mandiblearticulation, through which these glands release the secretion they produce. The mandibular glands ofthe minima, media and soldier worker of the ant Atta sexdens rubropilosa were analyzed by themethods of ultrastructural cytochemistry to verify the composition of the produced secretions. Theresults evidenced the presence of proteins, carbohydrates and lipids in the different portions of themandibular glands. The cytochemistry also showed that the lipids present in the mandibular gland ofthe individuals of three worker castes would have at least two different sources: the smoothendoplasmic reticulum as well as the mitochondria present in the secretory cells cytoplasm. Thepresent study showed that the mandibular glands of the individuals of the three worker castes of A. s.rubropilosa mainly the soldiers and media workers, who are individuals that perform tasks outside thenests and are thus more exposed to predation and/or infection and also the minima workers, who takecare of the fungal culture, produce compounds that could play roles in alarm and/or defense. |
