First Detection of Nosema ceranae, a Microsporidian Protozoa of European Honey­bees (Apis mellifera) In Iran [PDF]

Iranian Journal of Parasitology, 2011
Background: Nosemosis of European honey bee (Apis mellifera) is present in bee colonies world­wide. Until recently, Nosema apis had been regarded as the causative agent of the disease, that causes heavy economic losses in apicultures.

Ecological comparison of native (Apis mellifera mellifera) and hybrid (Buckfast) honeybee drones in southwestern Sweden indicates local adaptation.

PLoS ONE
Honeybee drones' only known task is to mate with a virgin queen. Apart from their mating behaviour, their ecology has been little studied, especially in comparison to honeybee females.

The foraging behaviour of honey bees, Apis mellifera: a review.

, 2018
Foraging behaviour is one of the distinctive behaviours of honey bees, Apis mellifera. This behaviour is the link between the honey bee colony and the ambient environment.

Pathogen spillover from Apis mellifera to a stingless bee

Proceedings of the Royal Society B, 2019
Pathogen spillover from managed bees is increasingly considered as a possible cause of pollinator decline. Though spillover has been frequently documented, evidence of the pathogen's virulence in the new host or mechanism of transmission is rare ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

In Search of Apis mellifera pomonella in Kazakhstan

Life, 2023
Apis mellifera pomonella is one of two subspecies that represent the eastern limits of honey bee (Apis mellifera) distribution, and it is important to understand its biogeography and evolution. Despite this, A. m. pomonella was not investigated after its discovery 20 years ago.

Multiomics Reveal Associations Between CpG Methylation, Histone Modifications and Transcription in a Species That has Lost DNMT3, the Colorado Potato Beetle

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Despite lacking DNMT3, EM‐seq revealed CpG methylation in the Colorado potato beetle. CUT&Tag analysis showed an association of H3K36me3 and H3K27ac with transcription, with H3K36me3 mirroring CpG methylation, demonstrating epigenetic flexibility.

Occurrence of deformed wing virus variants in the stingless bee Melipona subnitida and honey bee Apis mellifera populations in Brazil.

Journal of General Virology, 2019
The global spread of the parasitic Varroa mite has introduced a new bee to the bee horizontal transmission route for several RNA viruses that bypasses existing barriers in honey bees.
