Land Use and Season Interactively Affect Honeybee (Apis mellifera) Body Size and Fat Stores

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Habitat fragmentation and loss due to anthropogenic activities have impacted the foraging success of many animals, including pollinators. In this study, we found that summer honeybees in urban and mixed habitats were smaller and had greater wing wear but had larger fat stores compared to those in agricultural areas, where fat stores dropped during the ...

Genetic and Transcriptomic Basis of Enhanced Nectar and Resin Foraging in Honey Bees

open access: yesAgriculture
The collection of honey and propolis is crucial for the nutrition and health of honey bee colonies. In this study, Apis mellifera with high productivity for both honey and propolis (MJ) was developed through long-term selective breeding using Apis ...

Differences in the suitability of published honey bee (Apis mellifera) reference genes between the African subspecies Apis mellifera scutellata and European derived Apis mellifera

open access: yesMolecular Ecology, Volume 34, Issue 15, August 2025.
Abstract Quantitative real‐time polymerase chain reaction (qPCR) is a method widely used to determine changes and differences in gene expression. As target gene expression is most often quantified relative to the expression of reference genes, the validation of suitable reference genes is of critical importance.

Grooming behavior in relation to varroa (Varroa destructor) infestation level of Carniolan honey bee colonies (Apis mellifera carnica) [PDF]

open access: yesJournal of Central European Agriculture, 2018
Grooming behavior is one of the traits that enables Apis cerana resistance to ectoparasitic mite Varroa destructor. The study examines the proportion of damaged mites on 52 colonies (5 genotypes) of A. m. carnica in Croatia.

INVESTIGATION OF THE ANTIMICROBIAL EFFECT OF HONEYBEE VENOMS (APITOXIN) FROM APIS MELLIFERA CAUCASICA AND APIS MELLIFERA CARNICA

open access: yesUludağ Arıcılık Dergisi
The discovery of new therapeutic agents is crucial in the fight against antimicrobial resistance. The antimicrobial potential of apitoxin from Apis mellifera caucasica and A. m. carnica (Hymenoptera: Apidae) was tested in vitro against Gram-positive (Staphylococcus aureus ATCC-25923, Enterococcus faecalis ATCC-29212), Gram-negative (Escherichia coli ...

Floral diversity enhances winter survival of honeybee colonies across climatic regions

open access: yesJournal of Applied Ecology, Volume 62, Issue 6, Page 1487-1497, June 2025.
Our study highlights the critical role of including floral resource diversity and weather conditions in a comprehensive framework for studying honeybee hibernation. It suggests that increasing plant diversity around apiaries and implementing agricultural practices that enhance floral resources can significantly improve winter survival, with honeybee ...

Towards a Stable Host–Parasite Relationship Between Honey Bees and Varroa Mites Through Innovative Beekeeping

open access: yesEnvironmental Microbiology, Volume 27, Issue 5, May 2025.
An innovative Varroa treatment increases Varroa pressure and Deformed Wing Virus (DWV‐B) load in summer. The increased mite and virus levels are reduced with effective summer treatment so that finally there is no difference between both groups in terms of DWV‐B and mite load shortly before overwintering.

Correlation of Total Polyphenol and Flavonoid Content With Antioxidant Activity of Caucasian Bee Honey

open access: yesFood Science &Nutrition, Volume 13, Issue 1, January 2025.
This study includes the correlation between the phenolic contents and antioxidant activities of 54 Caucasian bee honey samples obtained from the Artvin and Ardahan regions, the most important gene centers of the Caucasian bee in Türkiye. The difference in the phenolic content and antioxidant activities of Caucasian bee honey is due to its geographical ...
