Maize (Zea Mays) or corn is one of the major cereal crops that is grown around the world. It ranks third in the production following Wheat and Rice. Of the various pests that attack Maize or corn in Europe, Africa and here in the United States, the Lepidopteran stalk borer is by far the most damaging. Here in the United States (Minesota, Iowa and Nebraska etc) Ostrinia nubilalis is one of the most destructive pests. It significantly affects growth and production.

This research focused on determining the possible effects of interaction of Beauveria bassiana, Trichogramma, Transgenic Bt sprays and Spinosad and their compatibility in an integrated pest management. The compared efficacy of these treatments for the economic control of Ostrinia nubilalis. To test the novel control tactics and integration of natural enemies in developing an economically effective and environmentally sound management program for the Ostrinia nubilalis.
