Abstract: Provided is a method for feeding invertebrates, comprising ? Providing a pollen substitute or supplement composition for invertebrates, in particular for honey bees and bumble bees out of yeast selected from the group consisting of S. cerevisiae, Xanthophyllomyces sp., S. japonicus or Yarrowia lipolytica, ? Administering the composition to invertebrates, wherein the composition is essentially free of ergosterol or zymosterol or combinations thereof.

Abstract: A method for feeding invertebrates comprising: ?providing a composition comprising a microbial organism or parts, extracts, oils or refinements thereof; and ?administering the composition to invertebrates wherein the microbial organism is selected from the group consisting of Saccharomyces cerevisiae, Xanthophyllomyces sp., S. japonicus or Yarrowia Hpolytica; and wherein the microbial organism has been genetically modified to produce an invertebrate nutrient selected from the group consisting of 24-methylene cholesterol, isofucosterol, cholesterol or desmosterol.

Abstract: Provided are methods for feeding invertebrates comprising: # providing a non-pollen composition comprising a nutritionally effective amount of proanthocyanidins; and # administering the non-pollen composition to invertebrates.

Abstract: Provided is a method for feeding invertebrates or aquaculture organisms comprising: #providing a non-pollen composition comprising a nutritionally effective amount of isofucosterol, fucosterol or a mixture thereof; and #administering the non-pollen composition to invertebrates.
