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

Ecological 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 ...

Within-bloom shift in abundance of a wild pollinator mediates pollen deposition rates to blueberry

Basic and Applied Ecology, 2023
Intra-seasonal variation in abiotic and biotic conditions can have profound consequences for pollinator community compositions and foraging movement, with flow-on effects upon pollination services.

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

Chemistry &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.

Fungivorous mites enhance the survivorship and development of stingless bees even when exposed to pesticides

Scientific Reports, 2022
Stingless bees are the largest group of eusocial bees in the world. They play an essential role as crop pollinators and have been considered for inclusion in pesticide risk assessments (RAs). Beyond the mutualism involving stingless bee larvae and fungi,

Morphological and Ecological Traits Explain Variation in Desiccation Tolerance Among Bees

Ecology 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

Journal 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 ...

Managed honey bee colony losses in Canada, China, Europe, Israel and Turkey, for the winters of 2008-9 and 1009-10 [PDF]

, 2012
In 2008 the COLOSS network was formed by honey bee experts from Europe and the USA. The primary objectives set by this scientific network were to explain and to prevent large scale losses of honey bee (Apis mellifera) colonies.

Nesting stingless bees in urban areas: a reevaluation after eight years

Sociobiology, 2016
Studies of nesting ecology have proven to be extremely important for stingless bee conservation. These studies have rarely been conducted in urban landscapes, and even fewer have compared species diversity and abundances over time.

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

Comprehensive 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 ...

Anti-inflammatory, antimicrobial and antioxidant activity of propolis and geopropolis produced by stingless bees

Stingless bees live in colonies ranging from hundreds to many thousands of individuals, but studies are scarce regarding resin, like the propolis of Apis mellifera.
