The effect of six different kinds of grass on the excretion rate of the cercopid Aeneolamia reducta was studied in a screen house and a growth chamber. The main objective was to measure the excretion rate of adult A. reducta on B. decumbes c.v.Basilisk (suscepti­ble), B. dictyoneura cv. Llanero (tole­rant), B. jubata CIAT 16531 (antibio­tic), and B. brizantha cv. Marandú (antibiotic). Wax membrane sachets were used for collecting insect excreta. Female A. reducta produced signifi­cantly greater quantities of excreta when placed on cv. Basilisk (1.6 ml/ insect/day) and cv. Llanero (1.5 ml/ insect/day) and cv. Marandú (0.6 ml/ insect/day). Gas chromatography of lyophilized samples of excreta of insects showed low sugar content indi­cating that adults fed from the xylem
