Honeybees gain viral protection from eating polypore extracts

Paul Stamets of Washington State University and colleagues tested whether diet supplementation of a sugar solution or extracts of the fungi Fomes fomentarius and Ganoderma resinaceum helped fend of viral infections such as honey bee deformed wing virus and Lake Sinai virus. In their field trials, colonies fed Ganoderma resinaceum extract exhibited a 79-fold reduction in Deformed wing Virus and a 45,000-fold reduction in Lake Sinai Virus compared to control colonies. These findings indicate honey bees may gain health benefits from fungi and their antimicrobial compounds and the researches suggested apiaries apply the extracts to
