GRACIOLI-VITTI, Luciana F.; ABDALLA, Fábio C.; MORAES, Regina L. M. Silva de  y  JONES, Graeme R.. The chemical composition of the mandibular gland secretion of Melipona bicolor Lepeletier, 1836 (Hymenoptera, Apidae, Meliponini): a comparative study among castes and sexes. J. Braz. Chem. Soc. [online]. 2004, vol.15, n.5, pp. 777-781. ISSN 1678-4790.

The mandibular gland secretions of newly emerged, nurse and forager workers, virgin and physogastric queens and males of Melipona bicolor were analyzed by gas chromatography-mass spectrometry. The secretion is composed of a blend of hydrocarbons, alcohols, esters, and acids. The secretion is caste-sex specific and also differs with the tasks performed by the workers and the physiological reproductive condition of the queens.
