“…In bees, the mandibular glands are sac-like structures found in front of the brain, differing in size and shape among the specimens considered (Cruz-Landim 1967, Graf 1970. The mandibular glands are found on each side of the head and open at the base of the mandible.…”

Summary Insect mandibular glands are always associated to the mandibles; they are part of the salivary glandular system. The mandibular glands are composed by a reservoir associated to the secretory cells, with each secretory cell connected to the reservoir by means of individual canaliculi. These glands play an important role in the production of pheromones, which are compounds involved in defense, communication, and reproduction of the colony. Mandibular glands of soldiers and major and minor workers of the ant Atta sexdens rubropilosa were processed for different histochemical tests, total protein content, and protein electrophoretic profile determination. The histochemical tests detected the presence of lipids, DNA/RNA, polysaccharides, and proteins at different regions of the gland. The protein electrophoretic profiles showed that the total protein content as well as the number of peptides of each caste follow a progressive order in relation to the size of the individual. Thus, we suggest that the production of secretion is directly linked to the task that the individual performs in the colony.

“…Em Cephalurgus anomalus essa característica também foi observada (Cunha et al 1990). Nos Bombini, primitivamente eussociais, a quantidade de glândulas tegumentares é muito grande e varia com as castas, sexos e tamanho das operárias, mostrando relação com a função de cada classe de indivíduo componente da colônia (Cruz-Landim 1967;Guerino & CruzLandim 2003b). Os resultados obtidos, ainda que prévios, indicam que em Melissoptila richardiae ocorrem glândulas tegumentares que, pelas características histológicas e comparações com a literatura, podem ser produtoras de feromônios.…”

ABSTRACT. Occurrence and morphology of tegumentary abdominal glands in Melissoptila richardiae (Bertoni & Scrottky) (Hymenoptera, Apidae, Eucerini). The occurrence and morphology of abdominal tegumentary glands were studied in Melissoptila richardiae. The results showed the existence of class III glandular cells that may appear as isolated units in tergites and sternites III and IV or forming clustered cells in both side of the tergites III and IV. In this late case the secretion is released in reservoirs derived from the tergite intersegmental membranes. The results suggest that this last gland products are lipidic and probably volatile.

“…The morphology of head glands that constitute individualized organs (salivary, mandibular and hypopharyngeal glands) is currently well known (Cruz-Landim, 1967;Costa-Leonardo & Cruz-Landim, 1977; and S. quadripunctata do not present fundamental differences regarding prior described conditions ( Fig. 2) of other Meliponini species.…”

“…Other workers later studied bee glands through a comparative morphological and distributive approach (Cruz-Landim, 1967, 1992, 1996Costa-Leonardo & Cruz-Landim, 1977). In certain species, the differences between sexes and castes regarding glandular presence or development were studied (Costa-Leonardo, 1978;CruzLandim et al, 1980a, b) and in others, even details on cell ultrastructure and secretion cycles are known (Cruz-Landim & Hadek, 1969;Cruz-Landim et al, 1998).…”

This article describes the location, anatomy, histology and ontogeny of adult Schwarziana quadripunctata exocrine glands. These glands appear either as individualized organs (salivary gland system and Dufour gland) or as epidermis differentiation (tegumentary glands). Variations in the occurrence and degree of development among colony components with regard to their degree of maturity are also described.Key words: exocrine glands, males, female castes, development. RESUMO Glândulas exócrinas de Schwarziana quadripunctata(Hymenoptera, Apinae, Meliponini)O presente artigo descreve a localização, a anatomia, a histologia e o desenvolvimento das glândulas exócrinas presentes em operárias, rainhas e machos de Schwarziana quadripunctata. As glândulas apresentam-se como órgãos individualizados (glândulas do sistema salivar e glândula de Dufour) ou como simples diferenciações da epiderme (glândulas tegumentares). As variações na ocorrência e no grau de desenvolvimento dos componentes da colônia, ou de seu grau de amadurecimento, também são apresentadas.Palavras-chave: glândulas exócrinas, machos, castas femininas, desenvolvimento.
