ULTRASTRUCTURE OF THE MANDIBULAR GLANDS OF PACHYCONDYLA-STRIATA ANTS (HYMENOPTERA, PONERINAE) .1. WORKERS

The mandibular glands of Pachycondyla striata workers consists of a proximal reservoir and secretory portion. The secretion is transported from the cytoplasm of the secretory cells to reservoir through individual canaliculi which is subdivided into two portions : an intracytoplasmatic and extracellular one. The reservoir consists of an epithelium made up of thin cells has a thick cuticle. The secretory cells showed a large amount of structures forming the citoskeleton always associated with myelin figures.
