Neonicotinoids in bees: a review on concentrations, side-effects and risk assessment
The proposed risk assessment scheme for systemic compounds was shown to be applicable to assess the risk for side-effects of neonicotinoids as it considers the effect on different life stages and different levels of biological organization (organism versus colony).
A restatement of the natural science evidence base concerning neonicotinoid insecticides and insect pollinators
This paper describes a project that set out to summarize the natural science evidence base relevant to neonicotinoid insecticides and insect pollinators in as policy-neutral terms as possible.
A Diverse Range of Novel RNA Viruses in Geographically Distinct Honey Bee Populations
It is shown that viral diversity in honey bee colonies is greater than previously thought, which encourages additional studies of the bee virome on a global scale and which may ultimately improve disease management.
Pyrrolizidine alkaloids in honey: comparison of analytical methods
Two analytical methods are used to determine PA content in honey and both showed good consistency in terms of PA-positive samples and quantification results, but the results showed significantly different quantifying results.
A restatement of recent advances in the natural science evidence base concerning neonicotinoid insecticides and insect pollinators
A summary is provided of recent advances in the natural science evidence base concerning the effects of neonicotinoid insecticides on insect pollinators in a format (a ‘restatement') intended to be
Single and interactive effects of Varroa destructor, Nosema spp., and imidacloprid on honey bee colonies (Apis mellifera)
Colonies as a superorganism may well be able to compensate at the colony level for sublethal negative effects of stressors on their individuals, and no effects of chronic sublethal exposure to imidacloprid on colony size or survival were found in this study.
How honey bees of successive age classes are distributed over a one storey, ten frames hive
There was a significant mortality of young bees in the first week after emergence in this study, which may be partly due to the study set up but is also a natural phenomenon.
Ammonium and nitrate nutrition inPlantago lanceolata andPlantago major L. ssp.major
P. lanceolata andP. major were grown in culture solutions with nitrate or ammonium as the nitrogen source. Dry matter accumulation in the shoot was faster with nitrate than with ammonium, whilst that
Winter Survival of Individual Honey Bees and Honey Bee Colonies Depends on Level of Varroa destructor Infestation
This study shows the correlation between long lifespan of winter Bees and colony loss in spring and shows that colonies treated earlier in the season had reduced V. destructor infestation during the development of winter bees resulting in longer bee lifespan and higher colony survival after winter.
