Research notes: Evaluation of soybean germplasm for resistance to corn earworm -- I
Corn earworm (Heliothis zea Boddie) is one of the most destructive pests of soybeans (Glycine max [L.] Merr.) and its infestation sometimes can cause complete crop loss (Turnipseed, 1973). This pest feeds on both the foliage and developing seeds in the pods. Soybeans become primary host as corn and cotton become more mature and consequently less attractive for oviposition (Freeman et al., 1967).
