Chemical Composition and Biological Activity of Propolis from Brazilian Meliponinae
Zeitschrift für Naturforschung C, 2000 Abstract Twenty-one propolis samples produced by 12 different Meliponinae species were analyzed by GC-MS. Several chemical types of stingless bees’ propolis could be grouped, according to the prevailing type of compounds like: “gallic acid”, “diterpenic” and “triterpenic” types.

Genetic breeding on the bee Melipona scutellaris (Apidae, Meliponinae) [PDF]
Acta Amazonica, 2006 A selection of queens of Melipona scutellaris through the most productive colonies were carried out during eight months in an orange honeyflow. Each of the colonies was evaluated by its production, that is, the gross weight production ( pollen, brood, geopropolis and wax of each hive).

Virgin queens in stingless bee (Apidae, Meliponinae) colonies: a review [PDF]
Apidologie, 1995 Les reines vierges dans les colonies d'abeilles sans dard (Apidae, Meliponinae): mise au point. Il existe plusieurs strategies pour maintenir les reines chez les especes d'abeilles sans dard. Elles incluent toutes une protection des reines vierges, au moins durant certaines periodes du cycle de la colonie. Chez les Meliponini, ou les reines emergent et

Genetic variability of behaviorin Melipona quadrifasciata(Hymenoptera: Meliponinae)
Brazilian Journal of Genetics, 1997 Observation colonies containing only young workers from 10 matrix colonies were set up to investigate the genetic aspects involved in task division in Melipona quadrifasciata. Wide variation among origins was observed for all behaviors analyzed, but these differences were significant only for brood cell construction and propolis ...

Note on glands present in meliponinae (Hymenoptera, Apidae) bees legs [PDF]
Revista Brasileira de Zoologia, 1998 The present paper reports the presence of glandular structures in legs of some stingless bee species. The glands appear as: the epidermis transformation in a glandular epithelium as in basitarsus, an epithelial sac inside the segment as in the femur of queens or in the last tarsomere, as round glandular cells, scattered or forming groupments.

Ginandromorfia em Melipona mondury Smith (Hymenoptera, Apidae, Meliponinae)
SITIENTIBUS série Ciências Biológicas, 2006 Pela primeira vez é descrita a ocorrência de um ginandromorfo de Melipona mondury, coletado juntamente com machos e fêmeas normais. O espécime possui assimetria bilateral, apresentando a metade direita da cabeça com caracteres de macho e a metade esquerda com caracteres de fêmea; o mesossoma apresenta caracteres de macho verificados principalmente pelo

Investigating Eusociality in Bees while Trusting the Uncertainty
Sociobiology, 2014 Phylogenetic hypotheses and estimates of divergence times have already been used to investigate the evolution of social behavior in all lineages of bees. The interpretation of the number of origins of eusocial behavior and the timing these events depends
