A review on the association of bacteria with stingless bees [PDF]

open access: yes, 2020
Most cultivable microbes associated with stingless bees are bacteria. Studies about bacteria related to stingless bee colonies were only limited to bacterial isolation and identification, while a few studies consider their potential applications ...

Comparative toxicity of fipronil, malathion, and thiamethoxam on the stingless bee Tetragonisca fiebrigi (Schwarz, 1938)

open access: yesActa Scientiarum: Biological Sciences, 2022
Stingless bees are important pollinators for various plant crops. We investigated the susceptibility of Tetragonisca fiebrigi to sublethal concentrations of insecticides fipronil, malathion, and thiamethoxam (administered through contact and ingestion ...

Honeybees directly outcompete other flower visitors through interference competition on shared resource

open access: yesEcological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

The diversity of honey bee and entrance characteristics of stingless bees nests at a meliponiculture in Batu Gadang, West Sumatra [PDF]

open access: yesBIO Web of Conferences
Honey bees, consist of true honey bee bees and stingless bees, are common in Indonesia. This study aimed to do the inventory on honey bee species as well as to study the entrance characteristics of stingless bee nests that exist at the meliponiculture in

Antioxidant Activities of Pentacyclic Triterpenes From Melipona beecheii Propolis and Their Semisynthetic Derivatives

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
M. beecheii propolis contains eleven identified PTs, including germanicone and glutinol, reported for the first time in this material. Antioxidant assays reveal Fe(III)‐reducing activity at an effective concentrations lower than DPPH radical‐scavenging activity.

Morphological and Ecological Traits Explain Variation in Desiccation Tolerance Among Bees

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We assessed the desiccation tolerance in 22 bee species from the Greek island of Lesbos. Larger bees lost water more slowly and survived longer, while survival declined with increasing water loss rate and water content at mortality. Morphological and ecological traits shaped physiological responses, highlighting trait‐based mechanisms underlying ...

Co‐Flowering Plant Species in a Glasshouse Boost Both Strawberry Production and Bee Health

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
Integrating co‐flowering plants into glasshouse strawberry systems creates a “win‐win” synergy where floral diversification enhances stingless bee vitality and crop visitation. This approach increased A‐grade fruit from 25% to 70%, demonstrating that strategic biodiversity integration optimises both pollinator health and sustainable agricultural ...

Amylosucrase as a Versatile Biocatalyst for Next‐Generation Functional Ingredients: Starch Modification and Glycoside Synthesis

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Amylosucrase (ASase, E.C. 2.4.1.4) is a transglucosidase that catalyzes α‐glucan synthesis and transglycosylation reactions using sucrose as the sole substrate. Unlike Leloir glycosyltransferases requiring expensive nucleotide sugars, ASases utilize readily available sucrose as a cost‐effective glucose donor, offering economic advantages for ...

Structural Colour in Bees (Hymenoptera: Anthophila) Is Linked to Climate and Latitude

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms—pigments or microscopic structures—has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables ...

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

open access: yesInsect Conservation and Diversity, Volume 19, Issue 5, Page 1061-1071, September 2026.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial
