Bioactive Fraction of Geopropolis from Melipona scutellaris Decreases Neutrophils Migration in the Inflammatory Process: Involvement of Nitric Oxide Pathway. [PDF]

Evid Based Complement Alternat Med, 2013
The aim of this study was to evaluate the activity of the ethanolic extract of geopropolis (EEGP) from Melipona scutellaris and its fractions on the modulation of neutrophil migration in the inflammatory process, and the participation of nitric oxide (NO) pathway, as well as to check the chemical profile of the bioactive fraction.

Revisiting the hymenopteran diploid male vortex: a review of avoidance mechanisms and incidence

Entomologia Experimentalis et Applicata, Volume 170, Issue 12, Page 1010-1031, December 2022., 2022
The Hymenoptera (bees, ants, wasps, and sawflies) have haploid males and diploid females. According to the diploid male vortex (DMV) theory, inbreeding increases sterile diploid male production and extinction risk for many species. We reviewed DMV incidence and avoidance.

Comportamento de nidificação de Melipona scutellaris (Latreille, 1811)

Research, Society and Development, 2021
A ambiência é um dos fatores relevantes na criação racional de abelhas. A abelha uruçu (Melipona scutellaris) é uma espécie nativa do Brasil, conhecida por sua grande produção de mel em relação aos demais meliponíneos e fácil manejo. A enxameação, porém, pode desestabilizar a produção de mel.

The significance of building behavior in the evolution of animal architecture

Ecological Research, Volume 37, Issue 3, Page 316-324, May 2022., 2022
Animals make a diverse array of architectures including nests, bowers, and tools. The relationship between the architecture itself and the construction behavior that built it is not straightforward and overlooking behavior risks obtaining an incomplete or even misleading picture of how animal architecture evolves.

Apis mellifera and Melipona scutellaris exhibit differential sensitivity to thiamethoxam

Environmental Pollution, 2021
Apis mellifera is a pollinator insect model in pesticide risk assessment tests for bees. However, given the economic and ecological importance of stingless bees such as Melipona scutellaris in the Neotropical region, as well as the lack of studies on the effect of insecticides on these bees, toxicity tests for stingless bees should be carried out to ...

Does effective population size affect rates of molecular evolution: Mitochondrial data for host/parasite species pairs in bees suggests not

Ecology and Evolution, Volume 12, Issue 2, February 2022., 2022
This study investigates a critical hypothesis in the field of evolutionary biology – whether rates of molecular evolution are higher in organisms with much smaller effective population sizes. To examine this issue, we compared rates of mitochondrial genes evolution between Australian host and parasite bee species when their effective population sizes ...

Antioxidant Properties and Characterization of Heterotrigona itama Honey from Various Botanical Origins according to Their Polyphenol Compounds

Journal of Food Quality, Volume 2022, Issue 1, 2022., 2022
Stingless bee honey is a good source of antioxidants, which is attributed to the phenolic compounds. The type and concentration of phenolic compounds in honey can be affected by botanical origin. Therefore, in this study, Heterotrigona itama honey from three botanical origins (gelam, acacia, and starfruit) was evaluated for its antioxidant activity and

Toxidade de produtos comerciais a base de Azadirachta indica em Melipona scutellaris (Hymenoptera: Apidae)

Diversitas Journal, 2020
RESUMO: Inseticidas botânicos têm sido utilizados no controle alternativo de insetos-praga por apresentarem menor risco ao ambiente, mas também podem atuar toxicamente em organismos benéficos, especialmente as abelhas, como a Melipona scutellaris ...
