Abstract

This study explores the spatial relationship between abundance of Russian wheat aphid, Diuraphis noxia (Mordvilko), and variation in edaphic and topographic factors within fields of wheat, Triticum aestivum L. Data from six wheat fields in Colorado, Wyoming, and Nebraska were analyzed by multiple regression. Data collected were numbers of Russian wheat aphids, aspect, relative elevation, slope, and percentages of clay and sand of soils at 25 geographically referenced sites in each field. Slope and percentage of sand explained 24.2% of the variation in Russian wheat aphid abundance within wheat fields in a model developed using stepwise regression.
