Four treatment modules were evaluated against mango hopper Idioscopus clypealis infesting mango crop for four consecutive years. The results revealed that the treatment module consisting imidacloprid (0.005%) followed by NSKE 5% endosulfan (0.07%) was found most effective in reducing hopper population(1.55 per panicle) with maximum fruit yield 219.10 Kg/tree followed by the treatment module consisting the use of thiamethoxam (0.008%) azadirachtin (1500 ppm) ethofenprox (10%) (3.55 hoppers per panicle) with fruit yield 175.20 Kg/tree.
