Abstract

Corn earwonn (Heliothis zea-Boddie) is a very destructive pest of soybeans (Glycine max [L.] Merrill). It feeds both on foliage as well as developing pods. Each larva is capable of damaging 6 to 8.2 pods or 7. 1 seeds between 4th and 6th (both inclusive) instars (Boldt et al., 1975; Smith and Bass, 1972).
