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 ...

Sociobiology, 2014 Melipona scutellaris Latreille has great economic and ecological importance, especially because it is a pollinator of native plant species. Despite the importance of this species, there is little information about the conservation status of their ...

Flight activity of Melipona asilvai Moure (Hymenoptera: Apidae)
Brazilian Journal of BiologyMany stingless bee species are specific to their areas of occurrence. Even when adapted to their local climate and flora conditions, they are subject to modifications in the environment, directly influencing flight activity.

Genetics and Molecular Research, 2009 Genetic models of sex and caste determination in eusocial stingless bees suggest specific patterns of male, worker and gyne cell distribution in the brood comb. Conflict between queen and laying workers over male parentage and center-periphery gradients of conditions, such as food and temperature, could also contribute to non-random spatial ...

EFFECTS OF BIOPESTICIDES IN Tetragonisca angustula LATREILLE (HYMENOPTERA: MELIPONINAE) POLLINATORS
Arquivos de Ciências Veterinárias e Zoologia da UNIPAR, 2020 Stingless bees Tetragonisca angustula (Latreille) (Hymenoptera: Meliponinae) are pollinators of native and cultivated plants, are therefore in contact with areas contaminated by pesticides. These native bees were evaluated for changes in gene expression of esterase isoenzymes and peptides after contamination by contact with insecticides growth ...

Responses to climatic factors by foragers of Plebeia pugnax Moure (in litt.) (Apidae, Meliponinae) [PDF]
Revista Brasileira de Biologia, 2001 Flight activity of Plebeia pugnax Moure (in litt.) was studied in six colonies coming from Cunha, SP, from July to October 1994. Twice a week, from 8:00 a.m. to 6:00 p.m., for 5 minutes every half-hour, all the bees entering and leaving the hives were counted. Six hundred counts were made and the materials that foragers carried were recorded. Data were

Genetic analysis of Melipona quadrifasciata Lep. (Hymenoptera: Apidae, Meliponinae) with RAPD markers [PDF]
Brazilian Journal of Biology, 2002 Melipona quadrifasciata ("mandaçaia") can be subdivided into two subspecies: M. q. anthidioides and M. q. quadrifasciata. In the present study we used RAPD markers to estimate intercolonial genetic variation among 69 colonies of Melipona quadrifasciata. Ten workers per colony were analyzed. The intercolony genetic distances based on RAPD markers ranged

Diversity and nesting characteristics of stingless bees in an urban green area, the Botanical Garden of Rio de Janeiro [PDF]
RodriguésiaGreen urban areas act as refuges for the nests of stingless bees, during reproduction, in response to niche constraints. This study investigated the characteristics of natural colonization by stingless bees in the arboretum of the Botanical Garden of Rio
