When African and European Lineages Meet: The Genetic Landscape of Honey Bees in Argentina

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Using a 272‐SNP panel, we explored how Africanized (AHB) and European (EHB) honeybee populations interact across Argentina's diverse landscapes. A clear latitudinal pattern in Africanization, with an interesting inverse relationship between African (A) and European (C) ancestry.

Performance of two honey bee subspecies during harsh weather and Acacia gerrardii nectar-rich flow

open access: yesScientia Agricola
Both climatic factors and bee forage characteristics affect the population size and productivity of honey bee colonies. To our knowledge, no scientific investigation has as yet considered the potential effect of nectar-rich bee forage exposed to drastic ...

In Vitro and In Vivo Effect of Amitraz on Honey Bee Drone Sperm Quality

open access: yesActa Zoologica, Volume 106, Issue 4, Page 493-502, October 2025.
ABSTRACT Honey bee hive infestation by the ectoparasitic mite, Varroa destructor, has been a major cause of declining populations. Treating such infestations is important for sustainability. Knowledge about the sub‐lethal effects of commonly used acaricides on drone reproductive health, particularly sperm quality, is limited. The effect of in vitro and

Heritability of grooming behaviour in grey honey bees (Apis mellifera Carnica) [PDF]

open access: yesActa veterinaria, 2010
Grooming behaviour is considered an important defensive mechanism of honey bees against Varroa mites. The aim of this study was to reveal whether grooming behaviour is a useful criterion in breeding of Varroa-tolerant bees. To obtain a reliable evaluation the environmental influences were excluded.

Transcriptomic analysis of the mandibular gland genes associated with reproductive dominance in Apis mellifera capensis Esch. parasitic workers

open access: yesPhysiological Entomology, Volume 50, Issue 3, Page 233-244, September 2025.
Biosynthesis of the fatty acid components of the Apis mellifera mandibular gland pheromones takes place in a stepwise manner. Differential gene expression in the mandibular gland tissue of workers from two subspecies of African honey bees with differing reproductive potentials and at two age groups was investigated.

Winterization techniques for populations of Apis mellifera ligustica and Apis mellifera carnica in western Montana

open access: yes, 2020
Winterization techniques for populations of Apis mellifera ligustica and Apis mellifera carnica in western Montana Agroecology Abstract: The relationship between domestic honey bees (Apis mellifera ligustica and Apis mellifera carnica) and winter in a ...

Population-wide modelling reveals prospects of marker-assisted selection for parasitic mite resistance in honey bees

open access: yesScientific Reports
In 2019, a joint eight-variant model was published in which eight single nucleotide polymorphisms (SNPs) in seven Apis mellifera genes were associated with Varroa destructor drone brood resistance (DBR, i.e. mite non-reproduction in drone brood). As this

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 ...

Dynamics of the content of trace elements in royal jelly of different breeds (subspecies) of honey bees depending on the month of its collection

open access: yesБіологія тварин
Royal jelly is a unique product of worker bees, namely the secret of their pharyngeal and maxillary glands. It is the main source of nutrients and biologically active substances for larvae and queens.

No chronic effects on biochemical biomarkers, feeding and survival of carnolian honeybees (Apis mellifera carnica) after exposure to nanosized carbon black and titanium dioxide

open access: yesActa Biologica Slovenica, 2016
Honeybees (Apis mellifera) are important pollinators threatened by environmental pollution, plan protection products and other potential contaminants.
