Abstract
Abstract The southern chinch bug, Blissus insularis Barber, is the most damaging insect pest of St. Augustinegrass, Stenotaphrum secundatum (Walt.) Kuntze. Historically, host plant resistance has been important for control of southern chinch bugs in St. Augustinegrass. In this study we screened 36 St. Augustinegrass varieties for resistance to southern chinch bugs. Four varieties were shown to have significant resistance using 2 different testing methods. Morphological data for these 4 varieties also were measured.
