Abstract
The effect of cholesterol deficiency on survival and reproduction of the adult house fly ( Musca domestica L.) was investigated. The preparation and composition of the synthetic diet used in these studies are reported. Although a cholesterol deficiency had no appreciable effect on adult survival or total egg production, it caused nearly an 80% reduction in egg hatch. Only about half the eggs that hatched from the flies fed the steroldeficient diet produced adults when reared on a larval medium containing sufficient sterols to support growth. Of the various cholesterol concentrations tested, 0.1% gave the highest cumulative hatch (92%) and a total viable egg production about 30% greater than that found for the control diet (sucrose: defatted dry milk solids 1:1).
