How is a changing climate reshaping the way honey bee colonies grow, forage, and survive winter? Dr. Gloria DeGrandi-Hoffman returns to Beekeeping Today Podcast to discuss her new book, The Honey Bee and Climate Change, and what nearly four decades of honey bee research have taught her about the connections among climate, nutrition, Varroa, and colony survival.
Gloria explains how unusually warm fall and winter weather can keep bees flying later in the year, changing colony age structure while extending opportunities for Varroa mites to move among colonies. At the same time, heat and drought can alter flowering periods and reduce both the quantity and nutritional quality of pollen and nectar available to bees.
The conversation explores the annual nutritional cycle of the colony, the differences between summer and winter bees, and why fall pollen can be so important for successful overwintering. Gloria also discusses research into cold-storage overwintering as one possible response to increasingly unpredictable fall conditions.
Finally, Jeff, Becky, and Gloria look at what beekeepers can do now: improve access to diverse forage, monitor and control Varroa carefully, consider mite-resistant stock, and recognize that yesterday's reliable management calendar may not always fit tomorrow's conditions.
