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 ...

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

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.

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

Genetics and Molecular Research, 2009 We describe a case of a spontaneously established mixed colony of two species of stingless bees. The host colony of Scaptotrigona depilis, an aggressive bee that forms large colonies, was invaded by workers of Nannotrigona testaceicornis, a smaller bee that forms small colonies.

Systematics, phylogeny and biogeography of the Meliponinae (Hymenoptera, Apidae): a mini-review [PDF]
Apidologie, 1992 Dans cet article de synthese sont discutees les principales propositions concernant la systematique, la phylogenese et la biogeographie des Meliponinae, ainsi que la polarite et l'importance de quelques caracteres morphologiques. Bien que tout un ensemble de synapomorphies (par ex les corbicules, le rastellum, l'articulation du basitarse posterieur ...
