Abstract

In screening experiments** to determine resistance of several commercial as well as introduced soybean germplasms, it was observed that European corn borer (Ostrinia nubilalis - Hbn), which is a major pest of sweet and field corn, was also infesting soybeans towards the end of the growing season in 1974. Generally the soybeans which were planted late (later than first week of June) were damaged. The larvae were found to bore into the stem, creating tunnels which consequently rendered the stem very brittle.
