A method to predict damage by Agrotis ipsilon (Hufnagel) in field corn, Zea mays L., was developed. It encompasses the cutting potential at given points in larval development and the influence of the corn growth stage on damage potential. Last instars cut more plants and lived ca. 3 times longer than any other. Therefore, a procedure to estimate the age of last instars based on body length (mm) was developed to improve control decisions. A head capsule measuring gauge was devised as an aid for determining the instar structure (% of the larvae in each instar) of black cutworm field populations.
