The development of Rhinocyllus conicus Froelich was evaluated on 52 artificial diets. Selected diet constituents were varied to determine their effects on weevil development. High mortality without initial feeding on diets with cholesterol suggested that phytosterol is essential as a phagostimulant. Only nine of the diets supported development of first instar larvae to the adult stage; sitosterol was present in each of the successful diets. The low yields of adult weevils indicate inadequacies in the diets.
