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

Molecular 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.

Environment or genetic isolation? An atypical intestinal microbiota in the Maltese honey bee Apis mellifera spp. ruttneri

Frontiers in Microbiology, 2023
IntroductionApis mellifera evolved mainly in African, Asian, and European continents over thousands of years, leading to the selection of a considerable number of honey bees subspecies that have adapted to various environments such as hot semi-desert ...

Integrative Genomics Reveals the Genetics and Evolution of the Honey Bee’s Social Immune System [PDF]

, 2019
Social organisms combat pathogens through individual innate immune responses or through social immunity—behaviors among individuals that limit pathogen transmission within groups.

In vivo continuous three-dimensional magnetic resonance microscopy: a study of metamorphosis in Carniolan worker honey bees (Apis mellifera carnica)

Journal of Experimental Biology, 2020
Three-dimensional (3D) magnetic resonance microscopy (MRM) is a modality of magnetic resonance imaging (MRI) optimized for the best resolution. Metamorphosis of the Carniolan worker honey bee (Apis mellifera carnica) was studied in vivo under controlled ...

Floral diversity enhances winter survival of honeybee colonies across climatic regions

Journal 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 ...

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

Scientific 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

Detection of novel probiotic bacterium Lactobacillus spp. in the workers of Indian honeybee, Apis cerana indica [PDF]

, 2012
Many insects are known to have microorganisms in the gut which can play an important role in their nutrition. In the present study, we report the presence of probiotic bacterium Lactobacillus spp. in the gut of the honeybee sub species Apis cerana indica

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

Environmental 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.
