Abstract: The present invention relates to starch foam microparticles having a porous structure, and which typically have a diameter of less than or equal to about 50 microns. The present invention also relates to novel uses for the starch foam microparticles in beekeeping and in the pharmaceutical, plastics and fragrance industries.

Abstract: The invention is directed to water-dispersible, substantially homogeneous artificial diets and diet formulations which provide honey bees with a fully nutritious, complex mixture of proteins, carbohydrates, fats, minerals, and vitamins in an easily digestible form. The diets of the invention support growth and development of honey bees, sustain brood rearing, and maintain hive vigor, and thus make possible the continuous rearing of bees using an artificial diet. The invention diets are useful for many purposes, and are particularly advantageous for providing nutrition sources for bees that are moved during commercial crop pollination or for other migratory beekeeping uses.
