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

A new species of Scaptotrigona from Belize (Hymenoptera: Apidae)

, 2022
A new species of the stingless bee genus Scaptotrigona Moure (Meliponini: Meliponina) is described and figured from a series of workers and drones from Belize.  Scaptotrigona (Astegotrigona) ascheri Engel, new species, may be distinguished from it ...

Population Divergence of Melipona scutellaris (Hymenoptera: Meliponina) in Two Restricted Areas in Bahia, Brazil

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 ...

Spatial patterns in the brood combs of Nannotrigona testaceicornis (Hymenoptera: Meliponinae): male clusters

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 ...

Flight activity of Melipona asilvai Moure (Hymenoptera: Apidae)

Brazilian Journal of Biology
Many 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.

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

Data from: Nesting ecology of stingless bees (Hymenoptera, Meliponina) in urban areas: the importance of afforestation

, 2013
Studies on nesting ecology have proven to be extremely important for conservation of stingless bees. This kind of study is scarce in urban landscapes. Our study aimed to analyze the abundance, density, diversity, spatial distribution and nesting habits ...
