Several functions of the secretions of particular exocrine organs are documented (communication, defense, self-protection, digestion etc.), but that of other such glands is still poorly understood. The structure of the exocrine glands of Prorhinotermes simplex (Hagen, 1858) was investigated using histological techniques. The development of the frontal, mandibular, labial, sternal, posterior sternal and tergal glands is described in larvae of the first and second instar, pseudergates, presoldiers, soldiers, pharate imagoes and imagoes. The exocrine glands of Prorhinotermes simplex are not functional during the first instar, except the labial glands, which may function from the time of hatching. Mandibular, labial and sternal glands start to differentiate during the second instar and acquire their definite structure and full function in the following instars.
