Abstract

Field trial to estimate losses due to sorghum shoot bug, Peregrinus maidis (Ashmead), revealed that, all unprotected plots recorded significantly higher sorghum stripe virus disease incidence (51.26% increase), higher shoot bug population (92.02 percent population increase) and leaf sugary exudation (63.86% increase) over protected plots. Overall 11.16 and 21.11 percent losses in grain and fodder yields, respectively were recorded.
