A replacement ingredient for hard-to-obtain and expensive dried cereal leaves was needed for preparing a low-cost black cutworm, Agrotis ipsilon (Hufnagel), diet. An alfalfa-based rabbit food, commercially prepared and readily available, was substituted for the cereal leaves. The effects of the replacement ingredient on A. ipsilon pupation, emergence, mating, and fecundity were examined for two black cutworm generations. Only pupal development was affected by the alfalfa-based diet. However, these pupal effects were variable between the two generations and no significant differences in pupal weight within the two generations were observed. The replacement ingredient exerted no significant influences on the other life stages examined. This modified diet has been successfully used for rearing black cutworm for 20 generations. Many noctuid species are reared on various ground-leaf products; thus the alternative diet may prove beneficial and economical.
