Both casein and yeast hydrolysate contain feeding stimulants for the adult female house fly. Guanosine monophosphate is the major active component in yeast hydrolysate. Several amino acids, including leucine, methionine, lysine, and isoleucine, are also effective feeding stimulants and are presumed to be the active components in the casein hydrolysate. Solution in phosphate buffer is necessary in all instances to obtain maximum activity with the stimulants.
