Pollen Harvest by Stingless Bee Foragers (Hymenoptera, Apidae, Meliponinae)

Grana, 1994
Abstract Data on pollen load capacity and flower constancy are discussed for nine stingless bee species. The foragers present high levels of flower constancy and often visit only one flower type (on average 97% of bee foragers), rarely a few flower types (on average 3% of bee foragers), during the same foraging trip.

Meliponinae and Apis mellifera honey in southern Brazil: Physicochemical characterization and determination of pesticides

Food Chemistry, 2021
This study evaluated the physicochemical parameters and the occurrence of pesticides in multi-flower honey produced by six species of Meliponinae and Apis mellifera and collected in different seasons, floral species and sites in southern Brazil. Meliponinae honey were found to exhibit higher moisture, free acidity and sucrose concentration and lower ...

Nestmate recognition of the stingless beeTrigona (Tetragonula) minangkabau (Apidae: Meliponinae)

Journal of Ethology, 1993
Nestmate recognition was studied in the Southeast Asian stingless beeTrigona (Tetragonula) minangkabau, a species in which worker oviposition has not been observed in queenright or queenless colonies. When conspecific non-nestmate foragers from queenright and queenless colonies were introduced to the observed colony, they were all rejected by guards ...

Stingless Bees (Meliponinae)

1988
Bombinae and Meliponinae are the only reasonably close relatives of honeybees. Since Meliponinae have many biological characteristics in common with Apinae (storage of honey, production and use of wax, perennial colonies of sometimes considerable size, division of labor), and since workers of some of the (bigger) species at first glance greatly ...

Características físico-químicas de samburá de Melipona grandis (Apidae: Meliponina) [PDF]

Scientia Naturalis
Samburá is the pollen collected from flowers by stingless bees (ASF) and stored in pots of cerumen inside the colony, where it is naturally fermented by enzymes from bees and associated microorganisms.

Geographic variation inTetragonisca angustula(Hymenoptera, Apidae, Meliponinae)

Journal of Apicultural Research, 2005
SUMMARYTetragonisca angustula is a small stingless bee occurring throughout Brazil as two subspecies. Tetragonisca angustula fiebrigi has a ferruginous coloured thoracic region (mesepisternum) and is found in south-western Brazil. In most parts of Latin America T. a. angustula, which has a black mesepisternum, is the common subspecies. A sample of T. a.

Ultrastructure of the ileum epithelium ofMelipona quadrifasciata anthidioides(hymenoptera, apidae, meliponinae)

Journal of Morphology, 1994
AbstractStudy of the epithelial morphology of a stingless bee ileum from the pyloric valve to the last portion of high absorptive cells shows that although the bee ileum is an anatomically undifferentiated tube, four types of epithelial cells along the tube (in addition to the valve cells) indicate physiological differentiation.

Foraging by Stingless Bees of the Genus,Scaptotrigona(Apidae, Meliponinae)

Journal of Apicultural Research, 1990
SummaryThe paper presents data on pollen and nectar foraging by Scaptotrigona bipunctata, S.depilis and S.postica in a disturbed community (the campus of Sao Paulo University, on the outskirts of Sao Paulo city), during a one-year period. Despite high local floral diversity, these bees exploited around 10 plant species and concentrated their pollen and
