Population density of Schizaphis graminum (Rondani) Was manipulated by use of insecticide to determine economic injury levels on grain sorghum. Based on previously published data and tests designed specifically to determine green bug number and plant damage required to cause significant grain losses, apparently a mean of ca. 1300- 1500 green bugs per plant at about the bloom stage of growth and mean leaf death in excess of 3 per plant were required to cause economic loss
