Ascorbic acid, an essential dietary ingredient for development of Trichoplusia ni (Hübner), can be satisfactorily substituted with other ascorbic acid derivatives, such as sodium or calcium ascorbate. Light apparently affected ascorbic acid, probably through oxidation, which in turn affected larval development. In a greenhouse test under natural light conditions, only a diet containing α-toco-pherol produced insect development comparable to that of the control held in the dark.
