[excerpt] One of the most interesting entomological developments in re- cent years has been the introduction of semi-synthetic diets for feed- ing lepidopterous larvae. Vanderzant and Reiser (1956a, 1956b) reared pink bollworms (Pectinophora gossypiella) on such a medium. The medium was subsequently modified by Ignoffo (1963), who experimented with mass-rearing of the cabbage looper (Trichoplusia ni), and by oth- ers. The method showing the most spectacular results is that of David and Gardiner (19651, which, since its publication, has been proven suitable for a number of species with diverse feeding habits. Although not a universal pabulum for larvae, the David-Gardiner formula de- serves to be better known in America as it solves two of the problems encountered in rearing many larvae; viz., it provides (1) a readily available food which may be (2) sterilized to eliminate disease.
