“…Meliponinae is genera of Hymenoptera, known as stingless bees, which is highly social organisms that occur in tropical and subtropical areas throughout the world, including Brazil. Propolis produced by stingless bees, is a mixture containing plant resin source, wax and clay or soil particles (Massaro et al, 2014, Carneiro, et al, 2016. A study demonstrated that Corymbia torelliana is the resin source for the elaboration of geopropolis from Australian Tetragonula carbonaria, as was evidenced by the great similarity in their methylated flavanone profiles by HPLC analyses of their respective extracts (Massaro et al, 2014).…”

The search for functional foods, which possess bioactive substances, is a new trend for the obtention of alternative and more effective treatments of many diseases with fewer side effects. Geopropolis, elaborated by stingless bees, is a mixture of plant resin sources, wax and soil. In the geopropolis from Scaptotrigona affinis postica (Latreille, 1807), (Hymenoptera, Apidae, Meliponini) was not observed the presence of soil. In a previous study, the extract of geopropolis provided by the beekeeper, from S. postica of Barra do Corda, Maranhão State, exhibited potent antiviral activity against herpes simplex virus. In this study, the propolis extract was prepared experimentally and characterized by RP-HPLC-DAD-ESI-MS/MS. The objective of this study was to evaluate the antiviral activity of an experimentally prepared geopropolis extract from S. postica against Rubella Virus infected Statens Serum Institute Rabbit Cornea (SIRC) cells. Rubella virus infection of susceptible women during the first trimester of pregnancy, often results in a combination of birth defects in newborns. There is not an effective treatment for rubella virus infection. Different protocols were carried out to evaluate, the antiviral effect of geopropolis extract on the viral replication of infectious RV. Cell viability and cell proliferation assays indicated that this geopropolis was not toxic to cultured SIRC cells. In the viral binding assay, antiviral assay, real-time PCR, and transmission electron microscopy, was observed that different concentrations of geopropolis (17, 34 and 68 µg/mL) was able to inhibit the binding of virions to the cell receptor and the production of infectious RV particles in post treated and pre treated infected SIRC cells. The antiviral activity could to be attributed to the high contents of the apigenin derivatives, vicenin-2 and schaftoside. As far as we know, this is the first report about the antiviral activity of geopropolis from Scaptotrigona postica against a Togaviridae virus.

Stingless bees (Hymenoptera, Apidae: Meliponini) represent a highly diverse group of social bees confined to the world's tropics and subtropics. They show a striking diversity of structural and behavioral adaptations and are important pollinators of tropical plants. Despite their diversity and functional importance, their ecology, and especially chemical ecology, has received relatively little attention, particularly compared to their relative the honeybee, Apis mellifera. Here, I review various aspects of the chemical ecology of stingless bees, from communication over resource allocation to defense. I list examples in which functions of specific compounds (or compound groups) have been demonstrated by behavioral experiments, and show that many aspects (e.g., queen-worker interactions, host-parasite interactions, neuronal processing etc.) remain little studied. This review further reveals that the vast majority of studies on the chemical ecology of stingless bees have been conducted in the New World, whereas studies on Old World stingless bees are still comparatively rare. Given the diversity of species, behaviors and, apparently, chemical compounds used, I suggest that stingless bees provide an ideal subject for studying how functional context and the need for species specificity may interact to shape pheromone diversification in social insects.
