Bienen werden anstelle von Honig mit Zuckerlösung ernährt

#Bienen produzieren den #Honig nicht zum Spaß. Sie brauchen die lebenswichtigen #Nährstoffe des #Honigs, die vor allem im Winter ihr Überleben sichern und sie im Sommer gegen #Milbenbefall schützen. In konventionellen Honigbetrieben ernähren #Imker:innen die Tiere jedoch mit einer billigen #Zuckerlösung . Dadurch sind sie sie anfälliger für #Krankheiten und damit einen frühen Tod.
In weiteren Studien müsse der Einfluss der verschiedenen Aktivierungsmuster auf die #Gesundheit geklärt werden. Offensichtlich sei aber schon jetzt, dass Honig bestimmte #Nährstoffkomponenten enthalte, die den #Ersatz-Zuckern fehlten.

NatureDiet-dependent gene expression in honey bees: honey vs. sucrose or high fructose corn syrup - Scientific ReportsSevere declines in honey bee populations have made it imperative to understand key factors impacting honey bee health. Of major concern is nutrition, as malnutrition in honey bees is associated with immune system impairment and increased pesticide susceptibility. Beekeepers often feed high fructose corn syrup (HFCS) or sucrose after harvesting honey or during periods of nectar dearth. We report that, relative to honey, chronic feeding of either of these two alternative carbohydrate sources elicited hundreds of differences in gene expression in the fat body, a peripheral nutrient-sensing tissue analogous to vertebrate liver and adipose tissues. These expression differences included genes involved in protein metabolism and oxidation-reduction, including some involved in tyrosine and phenylalanine metabolism. Differences between HFCS and sucrose diets were much more subtle and included a few genes involved in carbohydrate and lipid metabolism. Our results suggest that bees receive nutritional components from honey that are not provided by alternative food sources widely used in apiculture.
