InSchedorhinotermes lamanianus, size and cellular differentiation of the labial gland exhibit a caste-specific polymorphism. The acini of workers are composed of three distinct types of secretory cells, one of which is absent in soldiers and alates. The labial gland of workers releases a chemical signal for intraspecific communication. During the communal exploitation of a food source, labial gland secretion makes workers aggregate at gnawing sites where this signal is deposited. A newly developed bioassay is demonstrated.
