Population Dynamics Of Empoasca Fabae (Hemiptera: Cicadellidae) In Central Iowa Alfalfa Fields, L. A. Weiser Erlandson, John J. Obrycki
Population Dynamics Of Empoasca Fabae (Hemiptera: Cicadellidae) In Central Iowa Alfalfa Fields, L. A. Weiser Erlandson, John J. Obrycki
Entomology Faculty Publications
Adults and nymphs of Empoasca fabae Harris (Hemiptera: Cicadellidae) and adults of predatory species in the families Coccinellidae, Anthocoridae, Nabidae, Chrysopidae, and Hemerobiidae were sampled in Iowa alfalfa fields from June to September in 1999 and 2000. The relationship between each predatory taxa and E. fabae was examined using regression analysis. In 2000, all predators were found to be positively correlated with the presence of E. fabae during all periods sampled and most likely contributed to mortality. Orius insidiosus (Say) (Hemiptera: Anthoridae) was the most numerous insect predatory species; population numbers ranged from 0 to 1 and 0.1 to 3.7 …
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
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
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 …
