The concentrations of sugars were investigated in the Apis mellifera carnica drone brood in successive development stages. These stages are from the newly hatched larvae to the freshly emerged imago.

Recently, alongside novel compounds to defeat the pest, lithium chloride has been found to be effective.

Varroa destructor sucks the blood from both the adults and the developing brood, weakening and shortening the life span of bees.

A population of European honey bees surviving Varroa destructor mite infestation in Sweden for over 10 years without treatment.

Bees, these extraordinary creatures that have inhabited the Planet for over 100 million years, are the common thread that tells the story of various ecological challenges.

Pollen might be contaminated by multiple pesticides representing a risk for long-term contamination of honeybees when collected. Standardized methodology to assess the effects of pesticide mixtures under field conditions is lacking.

Here we quantified the duration and magnitude of neonicotinoid exposure in Canada’s corn-growing regions and used these data to design realistic experiments to investigate the effect of such insecticides on honey bees.

Microplastics were recently found in honey samples collected in Ecuador as well as in honey bees collected from Denmark and China.

These strategies consisted of online questionnaires and face-to-face interviews with beekeepers to record bee health issues. We found that use of both recruitment strategies was necessary because they reached different volunteer profiles and different locations

Citizen science is a powerful tool for connecting members of the public with research and for obtaining large amounts of data.
