Martins et al. (2015). Fig. 1 - intramandibular glands.

Martins et al. (2015) studied the occurrence of intramandibular glands in queens and soldiers, mediums, and minor workers using histological, histochemical, ultrastructural, and morphometric analyses. Individuals were obtained from three colonies of A. laevigata from Teixeiras (20 39’ S 42 51’ W), Minas Gerais, Brazil, and maintained in the Leafcutting Ants Laboratory at the Federal University of Vicosa. Class-3 gland cells and an epidermal gland with a reservoir were found in all the castes. The queens and soldiers showed a higher number of class-3 gland cells, distributed within the mandible as well as a greater gland size in comparison to the workers. There were also differences between castes in some chemical constituents.
