Preliminary characterization of mitochondrial genome of Melipona scutellaris, a Brazilian stingless bee. [PDF]

Biomed Res Int, 2014
Bees are manufacturers of relevant economical products and have a pollinator role fundamental to ecosystems. Traditionally, studies focused on the genusMeliponahave been mostly based on behavioral, and social organization and ecological aspects. Only recently the evolutionary history of this genus has been assessed using molecular markers, including ...

Characterization of antennal sensilla, larvae morphology and olfactory genes of Melipona scutellaris stingless bee. [PDF]

PLoS One, 2017
There is growing evidence in the literature suggesting that caste differentiation in the stingless bee, Melipona scutellaris, and other bees in the genus Melipona, is triggered by environmental signals, particularly a primer pheromone.

Insights into the Melipona scutellaris (Hymenoptera, Apidae, Meliponini) fat body transcriptome. [PDF]

Genet Mol Biol, 2013
The insect fat body is a multifunctional organ analogous to the vertebrate liver. The fat body is involved in the metabolism of juvenile hormone, regulation of environmental stress, production of immunity regulator-like proteins in cells and protein ...

10-hydroxy-2E-decenoic acid (10HDA) does not promote caste differentiation in Melipona scutellaris stingless bees. [PDF]

Sci Rep, 2021
In bees from genus Melipona, differential feeding is not enough to fully explain female polyphenism. In these bees, there is a hypothesis that in addition to the environmental component (food), a genetic component is also involved in caste ...

Antiproliferative Constituents of Geopropolis from the Bee Melipona scutellaris. [PDF]

Planta Med, 2016
Fractionation of geopropolis from Melipona scutellaris, guided by antiproliferative activity against two colon cancer cell lines (COLO205 and KM12), led to the isolation of two new cinnamic acid esters, mammea-type coumarins 5,7-dihydroxy-6-(3-methyl-2-butenyl)-8-(4-cinnamoyl-3-methyl-1-oxobutyl)-4-propyl-coumarin (1) and 5,7-dihydroxy-6-(4-cinnamoyl-3-

Differentially displayed expressed sequence tags in Melipona scutellaris (Hymenoptera, Apidae, Meliponini) development [PDF]

Anais da Academia Brasileira de Ciências, 2006
We have compared gene expression, using the Differential Display Reverse Transcriptase - Polymerase Chain Reaction (DDRT-PCR) technique, by means of mRNA profile in Melipona scutellaris during ontogenetic postembryonic development, in adult worker, and ...

Antimicrobial and antiproliferative activities of stingless bee Melipona scutellaris geopropolis. [PDF]

BMC Complement Altern Med, 2013
Abstract Background Geopropolis is a type of propolis containing resin, wax, and soil, collected by threatened stingless bee species native to tropical countries and used in folk medicine. However, studies concerning the biological activity and chemical composition of geopropolis are scarce.

Epigenetic modifications and their relation to caste and sex determination and adult division of labor in the stingless bee Melipona scutellaris. [PDF]

Genet Mol Biol, 2017
Stingless bees of the genus Melipona, have long been considered an enigmatic case among social insects for their mode of caste determination, where in addition to larval food type and quantity, the genotype also has a saying, as proposed over 50 years ...

Melipona scutellaris Geopropolis: Chemical Composition and Bioactivity

Microorganisms, 2023
Geopropolis has been used in traditional medicine for centuries. In this study, the botanical origin, physicochemical profile, and biological activities of geopropolis from Melipona scutellaris harvested during rainy and dry seasons were investigated ...

Retroelement expansions underlie genome evolution in stingless bees. [PDF]

BMC Genomics
Stingless bees serve as crucial pollinators and are increasingly recognized as models for investigating behavioral and genomic evolution in insects. In the genus Melipona, a major difference in heterochromatin organization defines two groups: Group I ...
