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

Journal 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.

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.

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 ...

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.

Pathogen and Hemocyte Dynamics in Three Apiaries Across a Bee Season

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Honey bees are dying due to a disease complex consisting of viruses, parasites, chemicals, nutritional deficiencies, and management problems. In the present study, pathogens and hemocytes were analyzed in honey bee hemolymph samples using third‐generation sequencing and flow cytometry in three apiaries over a honey bee season. Using nanopore sequencing,

Parasit-Wirtsbeziehungen zwischen Varroa destructor Anderson und Trueman und Apis mellifera L.

, 2005
Life of Varroa destructor, Anderson and Trueman, an ectoparasitic mite of honeybees, is divided into a reproductive phase in the bee brood and a phoretic phase during which the mite is attached to the adult bee.
