Transgenerational genomic analyses reveal allelic oscillation and purifying selection in a gut parasite Nosema ceranae

open access: yesFrontiers in Microbiology, 2022
Standing genetic variation is the predominant source acted on by selection. Organisms with high genetic diversity generally show faster responses toward environmental change.

Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

open access: yes, 2015
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

Neural Correlates of Social Behavior in Mushroom Body Extrinsic Neurons of the Honeybee Apis mellifera [PDF]

open access: yes, 2020
The social behavior of honeybees (Apis mellifera) has been extensively investigated, but little is known about its neuronal correlates. We developed a method that allowed us to record extracellularly from mushroom body extrinsic neurons (MB ENs) in a ...

Therapeutic Properties of Bioactive Compounds from Different Honeybee Products

open access: yesFrontiers in Pharmacology, 2017
Honeybees produce honey, royal jelly, propolis, bee venom, bee pollen, and beeswax, which potentially benefit to humans due to the bioactives in them. Clinical standardization of these products is hindered by chemical variability depending on honeybee ...

Learning and memory in the honeybee [PDF]

open access: yesThe Journal of Neuroscience, 1995
Insects are favorable subjects for neuroethological studies. Their nervous systems are relatively small and contain many individually identifiable cells. The CNS is highly compartmentalized with clear separations between multisensory higher order neuropiles in the brain and neuropiles serving sensory-motor routines in the ventral cord (Huber, 1974 ...

Neonicotinoids in the agroecosystem: In-field long-term assessment on honeybee colony strength and microbiome.

open access: yesScience of the Total Environment, 2020
Bees can be severely affected by various plant protection products (PPP). Among these, neonicotinoid insecticides are of concern as they have been shown to be responsible for extensive honeybee colonies death when released into the environment.

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.

Recombination and its impact on the genome of the haplodiploid parasitoid wasp Nasonia [PDF]

open access: yes, 2013
Homologous meiotic recombination occurs in most sexually reproducing organisms, yet its evolutionary advantages are elusive. Previous research explored recombination in the honeybee, a eusocial hymenopteran with an exceptionally high genome-wide ...

Dynamics of the Honeybee (Apis mellifera) Gut Microbiota Throughout the Overwintering Period in Canada

open access: yesMicroorganisms, 2020
Microbial symbionts inhabiting the honeybee gut (i.e., gut microbiota) are essential for food digestion, immunity, and gut protection of their host. The taxonomic composition of the gut microbiota is dynamic throughout the honeybee life cycle and the ...
