Flower visits, nesting and nest defence behaviour of stingless bees (Apidae: Meliponini): suitability of the bee species for meliponiculture in the Argentinean Chaco region
TLDR
Four bionomical features are here described for the seven stingless bees that inhabit a new meliponine beekeeping area: the Argentinean Chaco region, and a key to identify the Meliponini fauna of this region is provided.
Floral resources foraged by Geotrigona argentina (Apidae, Meliponini) in the Argentine Dry Chaco forest
TLDR
Pots with large amounts of monofloral loads with pollen from only a few species suggests an organised foraging behaviour that includes the recruitment of foragers, such as that observed in other eusocial bees.
Stingless Bees in Argentina
This contribution compiles current knowledge of stingless bees in Argentina. There are 33 species in 18 genera distributed in three areas. The highest diversity is found in the northeast, in the
Variability of Food Stores of Tetragonisca fiebrigi (Schwarz) (Hymenoptera: Apidae: Meliponini) from the Argentine Chaco Based on Pollen Analysis
TLDR
The foraging behavior of Tetragonisca fiebrigi was governed by random factors such as local differences of flower availability but not by preferences for some plant families, supporting the hypothesis that the Dry Chaco melittophilous vegetation is dominated by plants providers of both pollen and nectar.
Small pollen grain volumes and sizes dominate the diet composition of three South American subtropical stingless bees
TLDR
Measurements and descriptions of pollen cytoplasmic shapes as well as a new classification of pollen volumes based from measurements of the five pollen size categories using non-acetolyzed grains are provided.
Broad Protein Spectrum in Stored Pollen of Three Stingless Bees from the Chaco Dry Forest in South America (Hymenoptera, Apidae, Meliponini) and Its Ecological Implications
TLDR
Protein content of pollen stored by three meliponine species was variable, andPollen showing the highest protein content belonged to highly nectariferous plants well represented in melip onine and Apis honey such as Prosopis, Maytenus, and Ziziphus.
Are Stingless Bees a Broadly Polylectic Group? An Empirical Study of the Adjustments Required for an Improved Assessment of Pollen Diet in Bees
TLDR
Simple values were proposed to assess pollen diet of generalist bees: the maximum number of foraging items per nest and the maximum percentage value of foraged versus available items (adjusted) belong to a wider range of values that can be recognized as degrees of polylecty, allowing for a more precise identification.
Stingless Bees as Potential Pollinators in Agroecosystems in Argentina: Inferences from Pot-Pollen Studies in Natural Environments
TLDR
A high diversity of native meliponine species from many genera in northern Argentina is suitable for numerous trials on a large number of crops, including strawberry crops in the temperate area of Argentina.
Pollen host selection by a broadly polylectic halictid bee in relation to resource availability
TLDR
Pollen analysis complemented with field observations on floral resource availability proved to be helpful tools to provide information on the foraging behaviour of a wild bee in its natural environment.
Pollen diet assessment and flower association in Melipona orbignyi and recommendations on management and conservation of stingless bees in the Chaco dry forest of South America
TLDR
The rational rearing of Melipona orbignyi would be a good practice to be implemented to promote pollination of threatened tree and shrub individuals isolated by forest fragmentation.
