Extract

When a crop has been destroyed by the pale western cutworm, Agrotis orthogonia Morr., one to two weeks may elapse before plants of the second seeding emerge. During this time the larvae may be starved or, at least, subjected to a suboptimum food supply. Frequently the second seeding may be of a different crop from the one that was destroyed.

A previous investigation (Jacobson, 1952) showed that mortality of the starved larvae varied directly with temperature and inversely with size of larvae. Seamans and McMillan (1935) reported that, when the larvae were fed various foods, differences were found in the rate of development and survival.
