Reproduction of Varroa destructor in sealed worker bee brood cells of Apis mellifera carnica and Apis mellifera syriaca in Jordan [PDF]

, 2008
The reproduction of the honey bee mite, Varroa destructor in sealed worker bee brood cells represents an important factor for the population development of this parasite in honey bee colonies.

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

Physiological 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.

Gene flow in admixed populations and implications for the conservation of the Western honeybee, Apis mellifera [PDF]

, 2018
Anthropogenic activity, especially modern apiculture, has considerable impact on the natural distribution of the Western honeybee, Apismellifera, leading to the spread, replacement and fragmentation of many subspecies.

Solid + liquid equilibria and molecular structure studies of binary mixtures for nitrate ester's stabilizers: Measurement and modeling [PDF]

, 2018
Solid-liquid equilibria (SLE) data for two binary organic mixtures of N-(2-methoxyethyl)-p-nitroaniline+Nethyl- 4-nitroaniline (S1) and N-(2-ethanol)-p-nitroaniline+N-ethyl-4-nitroaniline (S2) have been measured using differential scanning calorimeter ...

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.

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

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 ...

Relationships between resistance characteristics of honey bees (Apis mellifera) against Varroa mites (Varroa destructor) [PDF]

Journal of Central European Agriculture, 2018
Ectoparasitic mite, Varroa destructor, today is one of the main reasons for colony losses worldwide. This study deals with relationships between measurements of resistance characteristics and measurements of bee infestation.

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 ...
