The purpose of this investigation was to determine the feasibility of using a combination control program for both broods of European corn borer larvae and the two injurious stages of the corn rootworms in Eastern Nebraska.
This research program consisted of two approaches. Each approach was designed to test the effectiveness of a combination program for controlling both the European corn borer and corn rootworm at specific stages in their life cycles.Early-season experiments were directed at first-brood corn borer and corn rootworm larvae while the late-season experiment was directed toward control of second-brood corn borers and adult corn rootworms.The experiments were composed of field plots located at specific locations in Eastern Nebraska during 1967 and 1968. Analyses were performed on the data and Duncan’s Multiple range test was used for determining significances.
