Extract

Larvae of the pale western cutworm, Agrotis orthogonia Morr., may be starved in the field by planned control (Seamans and Rock, 1945) or elimination of their food supply as a result of their own depredation. Starvation may occur at any time during the feeding period. Some effects of starvation on mortality, particularly in the early instars, have been reported (Jacobson, 1952). Larvae that were fed only two hours each day had an additional instar, developed more slowly, and were smaller (McGinnis and Kasting, 1959). Starvation during the fourth instar when the larvae were fed on various foods resulted in smaller pupae, and the size and fecundity of females were directly associated with pupal size (Jacobson and Blakeley, 1958).
