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 Paranaense forest, with 22 species, followed by the Yungas in the northwest, with ten species.

The American naturalist, 2016
The differentiation of workers into morphological subcastes (e.g., soldiers) represents an important evolutionary transition and is thought to improve division of labor in social insects. Soldiers occur in many ant and termite species, where they make up a small proportion of the workforce. A common assumption of worker caste evolution is that soldiers

Chemical Ecology of Stingless Bees
Journal of Chemical Ecology, 2017Stingless bees (Hymenoptera, Apidae: Meliponini) represent a highly diverse group of social bees confined to the world's tropics and subtropics. They show a striking diversity of structural and behavioral adaptations and are important pollinators of tropical plants.

To date, there has been relatively little formal research conducted on Australian stingless bees. However, the wealth of knowledge held by stingless bee enthusiasts is invaluable. Further scientific studies are needed to support these beekeepers and to help improve techniques in colony propagation, queen rearing, drone rearing, and, possibly ...

The stingless bees in Guatemala include at least 33 species that belong to 17 genera and are widely distributed in the country, at different altitudinal ranges and forest types. They forage on flowers of a wide diversity, potentially contributing to their pollination.

Insectes Sociaux, 2016
Bees are well known for being industrious pollinators. Some species, however, have taken to invading the nests of other colonies to steal food, nest material or the nest site itself. Despite the potential mortality costs due to fighting with an aggressive opponent, the prospects of a large bounty can be worth the risk.

Stingless Bees as Alternative Pollinators of Canola
Journal of Economic Entomology, 2015Alternative pollinators can ensure pollination services if the availability of the managed or most common pollinator is compromised. In this study, the behavior and pollination efficiency of Apis mellifera L. and two species of stingless bees, Plebeia emerina Friese and Tetragonisca fiebrigi Schwarz, were evaluated and compared in flowers of Brassica ...

The tropics and subtropics are home to thousands of different types of bees. One bee group that frequently calls an observer’s attention are the stingless bees or Meliponini. In the Neotropics, for example, about half of all bees that one is likely to see on flowers belongs to this group (Chap. 9).

Stingless bees and their adaptations to extreme environments
Journal of Comparative Physiology A, 2019Nearly half of all terrestrial tropical ecosystems around the globe comprise dry forests, characterised through elevated temperatures all year round, and short rainy seasons at irregular intervals. The consequent water deficit over several consecutive months limits the availability of floral resources to often very brief and unpredictable periods ...
