1. Regulation of membrane phospholipids during the adult life of worker honey bee.

Two female castes that are genetically identical are found in honey bees: workers and queens. Adult female honey bees differ in their morphology and behaviors, but the most intriguing difference between the castes is the difference in their longevity. Queens live for years while workers live...

2. Warmer winters are associated with lower levels of the cryoprotectant glycerol, a slower decrease in vitellogenin expression and reduced virus infections in winter honeybees.

Within the context of climate change, winter temperatures at high latitudes are predicted to rise faster than summer temperatures. This phenomenon is expected to negatively affect the diapause performance and survival of insects, since they largely rely on low temperatures to lower their metabolism ...

3. Environmental exposures associated with honey bee health.

Bee health is declining on a global scale, yet the exact causes and their interactions responsible for the decline remain unknown. To more objectively study bee health, recently biomarkers have been proposed as an essential tool, because they can be rapidly quantified and standardized, serving as a ...

4. Reproductive plasticity and oogenesis in the queen honey bee (Apis mellifera).

In the honey bee (Apis mellifera), queen and worker castes originate from identical genetic templates but develop into different phenotypes. Queens lay up to 2000 eggs daily whereas workers are sterile in the queen's presence. Periodically queens stop laying: during swarming, when resources are...

18. Pollen and landscape diversity as well as wax moth depredation determine reproductive success of bumblebees in agricultural landscapes.

Bumblebees are important pollinators in agricultural landscapes that are facing global declines. Main pressures include food scarcity mainly due to the reduction of semi-natural habitats (SNH) and parasite-induced vulnerability. Even though intensive agricultural landscapes are poor habitats for...
