Seasonal Abundance Of The European Corn Borer Ostrinia Nubilalis (Hbn.) Within The North Central United States, R. E. Hill, H. C. Chiang, A. J. Keaster, W. B. Showers, G. L. Reed

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Annual changes in corn borer populations in the North Central States were measured as a phase of a Regional Project, NC-20, entitled "Factors Influencing Corn Borer Populations" in Minnesota, Iowa, Kansas, Nebraska, Missouri and Ohio over a period of years. Standardized procedures were followed to estimate the seasonal abundance of the European corn borer, Ostrinia nubilalis (Hbn.), under cropping procedures in different locations within the North Central States. The primary purpose of the present bulletin is to present results for the 1965 to 1969 period and to compare these results with the previous 10 years and thus attempt to analyze …


European Corn Borer, Ostrinia Nubilalis (Hbn.) Populations In Field Corn, Zea Mays (L.) In The North Central United States, R. E. Hill, A. N. Sparks, C. C. Burkhardt, H. C. Chiang, M. L. Fairchild, W. D. Guthrie Aug 1967

European Corn Borer, Ostrinia Nubilalis (Hbn.) Populations In Field Corn, Zea Mays (L.) In The North Central United States, R. E. Hill, A. N. Sparks, C. C. Burkhardt, H. C. Chiang, M. L. Fairchild, W. D. Guthrie

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

A long-range study of the annual changes in corn borer populations in the North Central States was started in Minnesota, Iowa, Kansas and Nebraska in 1955 and in Missouri and Ohio in 1956. This investigation was a phase of a broader Regional Project, NC-20, entitled "Factors Influencing Corn Borer Populations" and was undertaken to measure by standardized procedures the seasonal changes in abundance of the European corn borer, Ostrinia nubilalis (Hbn.), under cropping procedures in different locations within, the North Central States. Much valuable information has been accumulated on the abundance and effects of various physical and biotic factors on …
