Sterilizing- activity of biotin was demonstrated with adults of the house fly, Musca domestica L. Diets containing as little as 0.25% biotin reduced egg hatch by about 50%, but continuous feeding on 2% biotin in food was necessary to effect complete sterility of females. Male flies were only slightly affected at a 2% dosage, and morphological changes in the testes were not apparent. Mortality increased with time but had not reached 50% in either sex at the end of a 15-day period. Females fed this medium for short intervals of 2-10 days were able to produce small numbers of viable eggs when returned to standard diet and mated with untreated males. Flies found normal food more palatable than biotin-treated medium. However, indications were that the sodium hydroxide solution used as the solvent for biotin was the principal cause of this response.
