Gut microbiota of Brazilian Melipona stingless bees: Dominant members and their localization in different gut regions. [PDF]

PLoS ONE
The gut microbiome of eusocial corbiculate bees, which include honeybees, bumblebees, and stingless bees, consists of anciently associated, host-specific bacteria that play crucial role in nutrition, pathogen defense and host fitness.

A molecular marker distinguishes the subspecies Melipona quadrifasciata quadrifasciata and Melipona quadrifasciata anthidioides (Hymenoptera: Apidae, Meliponinae) [PDF]

Genetics and Molecular Biology, 2000
The stingless bee species Melipona quadrifasciata includes two subspecies, Melipona quadrifasciata anthidioids and Melipona quadrifasciata quadrifasciata. The morphological difference between the two subspecies is the presence of three to five continuous

Insights into miRNAs of the Stingless Bee <i>Melipona quadrifasciata</i>. [PDF]

Noncoding RNA
MicroRNAs (miRNAs) are key post-transcriptional regulators involved in a wide range of biological processes in insects, yet little is known about their roles in stingless bees. Here, we present the first characterization of miRNAs in Melipona quadrifasciata using small RNAs (sRNAs) deep sequencing.

Geopropolis from <i>Melipona orbignyi</i> and <i>Melipona quadrifasciata anthidioides</i> Enhances Oxidative Stress Resistance and Lifespan in <i>Caenorhabditis elegans</i>. [PDF]

Pharmaceuticals (Basel)
Background: Oxidative stress arises from an imbalance in redox homeostasis, leading to the accumulation of reactive oxygen species. This condition is associated with premature aging, as well as the progression of several chronic noncommunicable diseases.

Nutritional Composition, Volatile Profiles, and Biological Evaluation of Honeys from Melipona interrupta and Melipona seminigra from Amazonas State, Brazil [PDF]

Plants
Honey is a natural product produced by bees from the nectar of plants and has been widely used as a sweetener for centuries. In addition to its traditional use, it is also employed for other purposes due to its biological and nutraceutical properties ...

Tragedy of the commons in Melipona bees revisited [PDF]

Biology Letters, 2022
Melipona stingless bees display a paradoxical overproduction of queens, which are later eliminated by nest-mate workers. Mechanistically, it was suggested that the monoterpenoid geraniol deposited into newly provisioned cells by adult bees would cause larvae to develop into queens in Melipona beecheii ...

Tragedy of the commons in Melipona bees [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004
In human society selfish use of common resources can lead to disaster, a situation known as the 'tragedy of the commons' (TOC). Although a TOC is usually prevented by coercion, theory predicts that close kinship ties can also favour reduced exploitation. We test this prediction using data on a TOC occurring in Melipona bee societies.

Management practices and honey characteristics of Melipona eburnea in the Peruvian Amazon [PDF]

Ciência Rural, 2020
: Meliponiculture and associated honey production are activities with a great potential for general use and commercialization in the Peruvian Amazon. Lack of management techniques and limited knowledge of honey quality are two factors which may hinder ...
