Genome-Wide Differential DNA Methylation in Reproductive, Morphological, and Visual System Differences Between Queen Bee and Worker Bee (Apis mellifera) [PDF]
Frontiers in Genetics, 2020 There are many differences in external morphology and internal physiology between the Apis mellifera queen bee and worker bee, some of which are relevant to beekeeping production.

Water provisioning increases caged worker bee lifespan and caged worker bees are living half as long as observed 50 years ago [PDF]
Scientific Reports, 2022 The high loss rates of honey bee colonies drive research for solutions aimed to mitigate these losses. While honey bee colonies are superorganisms, experiments that measure the response to stressors often use caged individuals to allow for inference in a

Caste-dependent sleep of worker honey bees [PDF]
Journal of Experimental Biology, 2008 SUMMARYSleep is a dynamic phenomenon that changes throughout an organism's lifetime, relating to possible age- or task-associated changes in health,learning ability, vigilance and fitness. Sleep has been identified experimentally in many animals, including honey bees (Apis mellifera).

Senescence in the worker honey bee Apis Mellifera [PDF]
Journal of Insect Physiology, 2007 Honey bees are social insects that exhibit striking caste-specific differences in longevity. Queen honey bees live on average 1-2 years, whereas workers live 2-6 weeks in the summer and about 20 weeks in the winter. It is not clear whether queen-worker differences in longevity are due to intrinsic physiological differences in the rate of senescence, to

Evolutionary trends in Bombella apis CRISPR-Cas systems [PDF]
mSystemsBacteria and archaea employ a rudimentary immune system, CRISPR-Cas, to protect against foreign genetic elements such as bacteriophage. CRISPR-Cas systems are found in Bombella apis. B.

Starving honey bee (Apis mellifera) larvae signal pheromonally to worker bees [PDF]
Scientific Reports, 2016 AbstractCooperative brood care is diagnostic of animal societies. This is particularly true for the advanced social insects and the honey bee is the best understood of the insect societies. A brood pheromone signaling the presence of larvae in a bee colony has been characterised and well studied, but here we explored whether honey bee larvae actively ...

Mechanistic exploration of royal jelly production in caged honey bees (Apis mellifera) [PDF]
Scientific ReportsThis study investigates the impact of bee pollen nutrition on the royal jelly production of honey bees (Apis mellifera). Results demonstrate that pollen diet significantly impacts hypopharyngeal gland (HPG) development and the expression of genes ...

Methylation and worker reproduction in the bumble-bee (Bombus terrestris) [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2014 Insects are at the dawn of an epigenetics era. Numerous social insect species have been found to possess a functioning methylation system, previously not thought to exist in insects. Methylation, an epigenetic tag, may be vital for the sociality and division of labour for which social insects are renowned.

Morphological Comparisons of Adult Worker Bees Developed in Chinese and Italian Honey Bee Combs [PDF]
InsectsThe size of comb cells is a key factor influencing the body size of honey bee workers. Comb cells and the body size of Chinese honey bee workers are smaller than those of Italian honey bee workers.
