In-depth proteomic analysis of Varroa destructor: Detection of DWV-complex, ABPV,...

Abstract We investigated pathogens in the parasitic honeybee mite Varroa destructor using nanoLC-MS/MS (TripleTOF) and 2D-E-MS/MS proteomics approaches supplemented with affinity-chromatography to concentrate trace target proteins. Peptides were detected from the currently uncharacterized Varroa destructor Macula-like virus (VdMLV), the deformed wing virus (DWV)-complex and the acute bee paralysis virus (ABPV). Peptide alignments revealed detection of complete structural DWV-complex block…

The genomes of two key bumblebee species with primitive eusocial...

Abstract Background The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will…

Relating climatic factors to foraging behavior of bees during blooming...

Abstract The present study was conducted at Mekelle Agricultural Research Center with the objective of determining the foraging behavior of local honeybees in relation to climatic factors. This was done during the blooming time of Guzotia abyssinica (LF). The data were collected during five observations at time intervals of: 8:30-3:30 AM, 10:30-11:30AM, 12:30-13:30PM, 14:30-15:30 PM…

Presence of Nosema ceranae associated with honeybee queen introductions

Abstract Microsporidiosis caused by Nosema species is one of the factors threatening the health of the honeybee (Apis mellifera), which is an essential element in agriculture mainly due to its pollination function. The dispersion of this pathogen may be influenced by many factors, including various aspects of beekeeping management such as introduction of queens with…
