Technical Abstract: Diets containing sucrose or pure glucose as the carbohydrate sweetner rapidly lost water, hardened, and became difficult for the bees to eat. Reduction of the glucose level to 75% or less and replacement of sucrose with fructose yielded a soft, acceptable diet texture that lost little water and could be readily consumed by bees. A sugar combination of 50% fructose and 50% glucose appeared ideal for incorporation in bee diets. Feeding choice preference tests using 1-3 day old honey bees revealed that addition of pollen extract phagostimulant increased diet consumption over non-treated controls. Addition of as little as 1 to 5% pollen extract significantly enhanced feeding behavior in all diets tested. Phagostimulant enhancement of seven commercial honey bee substitute diets for dietary ingredients was analyzed for nutritional potential in longevity tests. The diets differed in the time lengths of bee survival, suggesting potential differences among the nutritional values of the diets. A complicating factor was the presence of heavy parasite loads of varroa mites on the bees.
