The black queen cell virus (BQCV) is a common agent that causes covert infection in hives and has a global distribution. In this study, TaqMan probe and EvaGreen (EG) dye-based real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) assays based on the amplification of coding senquences for the BQCV structural protein (SP) and the non-structural protein (NSP) were developed and validated for the detection of BQCV in adult bee and larvae/pupae. Additionally, the performances of commonly used EG and TaqMan chemicals for real-time qRT-PCR analyses were compared.

While the gut microbiota of honey bee queens, workers, and larvae has been extensively studied, less is known about the composition of gut microbiota in the winter worker bees. This study investigates the dynamics of the gut microbiota in overwintering adult worker bees, focusing on two commercial bee strains: Bolton™ bees and Mann Lake™ bees.

The bacterium is responsible for the devastating honey bee () disease American Foulbrood. Research into bacteriophages that infect is growing rapidly due to increasing antibiotic resistance and restrictions on antibiotic use in beehives in some countries. In this study, we present the sequenced and annotated genomes of 26 novel phages recently isolated in New Zealand, which brings the total number of sequenced and annotated phages to 96.

Background: The Kashmir bee virus (KBV) infects many species of Hymenoptera, including bees, wasps, and other pollinators, potentially contributing to honeybee population declines. KBV can cause death of bees. KBV can infect through both vertical transmission (from queen to larvae and vice versa) and horizontal transmission (via food contamination).

The composition of the gut microbiota in animals can be influenced by a variety of intrinsic and extrinsic factors in the host, such as diet, physiological state, and genetics. This study aimed to compare the structural composition of the gut microbiota of Apis mellifera bees from two distinct Brazilian biomes, the Atlantic Forest and the Caatinga, using high throughput 16 S rRNA sequencing. We identified a core microbiota composed of seven genera present in all samples: Lactobacillus, Commensalibacter, Rhizobiaceae, Snodgrassella, Gilliamella, Orbaceae and Bifidobacterium.
