“…In fact a causative explanation can only be found in carefully designed risk assessment studies at colony level. Also, other factors such as nutrientquality of pollen available to honey bee colonies could play a role in our findings Höcherl et al, 2012 This study demonstrates that beekeepers who treated the varroa mite in summer and winter experienced lower risks of winter loss. A varroa treatment strategy with formic acid in summer and oxalic acid in winter was by far the most commonly used product combination in the strategies used by the beekeepers in our dataset.…”

Generalised linear mixed effects models (GLMMs) were used to investigate the effects of several factors on the risk of colony loss, including different treatments for Varroa destructor, allowing for random effects of beekeeper and region.Both winter and summer treatments were considered, and the most common combinations of treatment and timing were used to define treatment factor levels. Overall and within country colony loss rates are presented. Significant factors in the model were found to be:percentage of young queens in the colonies before winter, extent of queen problems in summer, treatment of the varroa mite, and access by foraging honey bees to oilseed rape and maize. Spatial variation at the beekeeper level is shown across geographical regions using random effects from the fitted models, both before and after allowing for the effect of the significant terms in the model. This spatial variation is considerable.

“…In our study, brood production did not differ between colonies fed PS or pollen possibly because it occurred in the winter when brood rearing rates are low. In a study comparing PS with pollen in summer, brood rearing was lower in those fed PS (Hocherl et al 2012).…”

Honey bee colonies provided with natural forage have lower pathogen loads and higher overwinter survival than those fed protein supplements

-Malnutrition is a major cause of colony losses. In managed hives, bees are fed protein supplements (PS) during pollen shortages. If bees were provided with natural forage instead of PS, would they have lower pathogen levels and higher queen and colony survival? We addressed this question by either providing colonies with forage (Brassica rapa -rapini) or feeding them PS from November to February. Soluble protein concentrations in the PS were lower than the rapini pollen as were levels of most amino acids. Nurse bees digested less of the protein in PS than the pollen. Hemolymph protein titers in nurse bees and colony growth did not differ between those fed PS or foraging on rapini. However, colonies fed PS had higher levels of black queen cell virus and Nosema and greater queen losses, indicating that natural forage might improve overwintering survival.pollen nutrition / digestion / amino acids / Nosema / viruses

“…More recent cage experiments showed a weak upregulation of antimicrobial effectors at the protein level in infected bees fed with a diet of polyfloral pollen and honeydew honey (Höcherl et al 2012). Again, either pollen could have facilitated an immune system upregulation in P. larvae -infected individuals or specific antibacterial components may be released by the partial digestion of pollen (Rinderer et al 1974).…”

Pharmacophagy and pharmacophory: mechanisms of self-medication and disease prevention in the honeybee colony (Apis mellifera)

-Apitherapy promises cures for diseases in human folk medicine, but the effects of honeybee produced and foraged compounds on bee health are less known. Yet, hive products should chiefly facilitate medication and sanitation of the honeybees themselves rather than other organisms. We here review the impact of both self-produced gland secretions and foraged hive products (pharmacognosy) on colony health. Although foraged plant-derived compounds vary highly in antibiotic activity depending on the floral and regional origins, secondary plant metabolites in honey, pollen and propolis are important for the antibiotic activity against pathogens and parasites. However, specific bee health-enhancing activities of bee products should clearly be distinguished from the effects of an intact nutrition ensuring the basic immune competence of bees. Further unravelling the interactions among groups of active substances or individual compounds used in concert with specific behavioural adaptations will deepen our understanding of the natural potential of honeybees to maintain colony health.honey / propolis / pollen / bee bread / royal jelly / antimicrobial activity / self-medication / host-parasite interaction
