Field experiment was conducted during autumn of 1989 of find out the effect of silicon on leafhoppers and to determine the relationship between green leafhoppers and their predators. A significant reduction of green leafhopper population was observed with higher silicon doses. Population abundance of green leafhoppers showed negative correlations with their predators namely damselflies, spiders and lady bird beetles. Path coefficient analysis reveals that abundance of spiders had the maximum negative direct effect on green leafhopper abundance followed by the lady bird beetles.
