The genomes of two key bumblebee species with...

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…

Disentangling multiple interactions in the hive ecosystem

Abstract The widespread losses of honeybee colonies recorded over the past number of years in the northern hemisphere represent a major concern for the beekeeping industry and, more importantly, may have a severe impact on ecological services and biodiversity. There is now a general consensus about the multifactorial origin of colony losses, but the mechanistic…

Relating climatic factors to foraging behavior of bees...

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…

Dynamic of the Presence of Israeli Acute Paralysis...

Abstract The determinants of Colony Collapse Disorder (CCD), a particular case of collapse of honey bee colonies, are still unresolved. Viruses including the Israeli acute paralysis virus (IAPV) were associated with CCD. We found an apiary with colonies showing typical CCD characteristics that bore high loads of IAPV, recovered some colonies from collapse and tested…
