Vertical transmission of honey bee viruses in a Belgian queen breeding program [PDF]

, 2015
Background: The Member States of European Union are encouraged to improve the general conditions for the production and marketing of apicultural products. In Belgium, programmes on the restocking of honey bee hives have run for many years.

Effects of Queen Rearing Technology of Apis cerana by Cutting Comb on Reproductive Capacity and Productive Performance

Agriculture
The queen, as the reproductive core of a honeybee colony, has declining reproductive capacity with age, making it necessary to rear new queens to replace older ones.

Efficient Methods for Rearing Strong Bee Queens

Scientific Papers Animal Science and Biotechnologies, 2023
The aim was to choose the most efficient method to rear genetically strong queens: by overcrowding swarm or by orphaning the bees. The experiment was conducted in a private apiary in Teleorman County, between April and September 2015.

Honey bee retinue workers respond similarly to queens despite seasonal differences in Queen Mandibular Pheromone (QMP) signaling.

PLoS ONE, 2023
Honey bee colonies maintain viable queens in part through communication with Queen Mandibular Pheromone (QMP), a mixture that signals the queen's presence and reproductive quality to workers.

Effects of developmental exposure to pesticides in wax and pollen on honey bee (Apis mellifera) queen reproductive phenotypes

Scientific Reports, 2021
Stressful conditions during development can have sub-lethal consequences on organisms aside from mortality. Using previously reported in-hive residues from commercial colonies, we examined how multi-pesticide exposure can influence honey bee (Apis ...
