Seasonal Pollens and Nutrition Research with Dr. Gloria DeGrandi-Hoffman (S4, E14)

Today we talk with Dr. Gloria DeGrandi-Hoffman. Gloria is the Research Leader at the Carl Hayden Bee Research Center in Tucson, Arizona. Gloria and the researchers there are involved in several projects, but today we talked to her about just two that are both new and promising for beekeepers and their bees. Modeling honey bee nutrition requirements on a seasonal basis is an area that has not received much attention to date, as they have been for many other animals. It turns out that the pollens that bees collect satisfy those requirements on a seasonal basis. High energy in spring with large amounts of amines and fatty acids for brood rearing, less so in summer and more towards storage use in the fall for overwintering. This may affect pollen feeding, and pollen substitute formulas to optimize their diets at the right time. But there are both seasonal and regional differences in pollen quality, and what is being noted is that with climate change affecting the phenology of blooming dates, bees may not be able to get the food they need when they need it. Another project being studied is overwintering colonies in climate-controlled buildings. They are looking at how much food will a colony need to do this, what the population should be when they enter a building, and when should they come out of storage so that they are ready to build fast for early pollination work, or later for honey flows. In addition, they are researching the best time for a season's mite controls to be placed for optimum control and honey bee health. Along with this they looked at cost efficiencies relative to winter losses, feed costs, colony strength and labor and made some interesting finds relative to these costs.

Each page of the magazine is dedicated to the stories and photos of all pollinators and written by leading researchers, photographers and our very own, Kim Flottum. HiveAlive is the #1 feed supplement for honeybees worldwide. HiveAlive has been proven to give more bees, more honey, improved overwinter survival and improved intestinal wellbeing. It contains a unique blend of seaweed extracts, thyme and lemongrass. Whilst it is unusual for bees to be fed seaweed, the practice of adding seaweed to other animal feed is long established. Seaweeds are fed to animals for multiple benefits such as productivity, general health, gut health, immune function and nutrition. As well as providing multiple benefits for the bees, HiveAlive is super easy to use and also prevents syrup from fermenting. Simply add just 2 tsp of our concentrated formula per gallon of syrup. Due to demand from beekeepers, we have also created HiveAlive Fondant Patty. This gives all the benefits of HiveAlive in a ready to feed sugar fondant with added vitamins & amino acids. The patties are individually sealed meaning they won't dry out and are thin to allow easy placement close to the cluster. These patties are ideal for feeding colonies over winter and for emergency feeding of colonies. Ask for HiveAlive and our new HiveAlive Fondant Patty at your local beekeeping store or find it online at https://usa.hivealivebees.com/ .
