Abstract
The cultivars "Reno" barley, "Arkwin" oats, "Balbo" rye, and "Ponca" wheat, which served for culturing Schizaphis graminum (Rond.) (biotype C) prior to testing did not predispose the greenbugs to different preferences for cultivar food-plants. However, bugs reared on "RS 671" sorghum, showed a definite preference for sorghum compared with bugs cultured on oats, rye and wheat. Overall, rye was least preferred and barley most preferred. The culture host cultivar did not influence the number of days to reproduction or nymphs produced per day, but the host on which the bug was living had a decided influence on these factors. Non-preference for resistant "KS 30" sorghum vs. susceptible "RS 671" sorghum was not influenced by the host cultivar on which the bug was cultured but decreased with a decrease in temperature
