Biogeography from a food matrix: a temporal distribution map of Apis mellifera mitochondrial DNA lineages across Italy, obtained from honey samples [PDF]

Scientific Reports
The genetic integrity of European Apis mellifera subspecies has been increasingly threatened. Mitochondrial DNA (mtDNA) analysis is widely used to investigate honey bee lineage distribution. Honey represents a valuable source of environmental DNA (eDNA),

Interception of an Apis dorsata swarm with Tropilaelaps mercedesae and Kuzinia morsei mites on a cargo vessel inbound to the United States [PDF]

Frontiers in Insect Science
In 2025, a swarm of giant honey bees, Apis dorsata dorsata, was detected on board a cargo vessel prior to arrival at the port of Elizabeth, New Jersey, USA.

Human-mediated introgression and Varroa destructor shaped the genetic structure of honey bee populations in the Azores [PDF]

Scientific Reports
The evolutionary trajectory of island populations can be rapidly altered by human-mediated migration, a process further exacerbated when immigrants introduce invasive parasites, creating new selective pressures.

Introgression of lineage c honey bees into black honey bee populations: a genome-wide estimation using single nucleotide polymorphisms (SNPS)

, 2012
The black honey bee, Apis mellifera mellifera L., is probably the honey bee subspecies more threatened by introgression from foreign subspecies, specially lineage C A. m. carnica and A. m. ligustica. In fact, in some areas of its distributional range, intensive beekeeping with foreign subspecies has driven A. m.

Chemical Markers and Bioactivity of Algerian Royal Jelly: Influence of Bee Subspecies, Geography, and Lyophilization [PDF]

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Algerian royal jelly from native honey bees shows chemical diversity influenced by geography and subspecies. Lyophilization preserves key compounds, including 10‐HDA and phenolics. Biological assays reveal modest antioxidant activity and selective cytotoxicity against Reh leukemia cells, while anti‐inflammatory effects are limited.

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

Ecology and Evolution
ABSTRACT Argentina has a complex and diverse landscape of honeybee ( Apis mellifera sp.) populations shaped by historic introductions and hybridization between Africanized (AHB) and European (EHB) lineages.

Nosemosis in Russian Apis mellifera L. Populations: Distribution and Association with Hybridization [PDF]

Insects
One of the common causes of mass death in bee colonies is the infectious disease nosemosis, which is caused by two types of microsporidia, Nosema apis and Nosema ceranae.

Evolutionary Origin and Genetic Diversity of the Pannonian Ecotype of Apis mellifera carnica Colonies in Hungary Based on Mitochondrial DNA and Microsatellite Markers [PDF]

Biology
Honey bees are crucial to both the ecosystem and the economy. However, they are subject to different influences that can lead to a loss of genetic diversity.

Selection on overdominant genes maintains heterozygosity along multiple chromosomes in a clonal lineage of honey bee. [PDF]

Evolution; international journal of organic evolution, 2014
Correlations between fitness and genome-wide heterozygosity (heterozygosity-fitness correlations, HFCs) have been reported across a wide range of taxa. The genetic basis of these correlations is controversial: do they arise from genome-wide inbreeding ("general effects") or the "local effects" of overdominant loci acting in linkage disequilibrium with ...
