A Field study was conducted to devise a scheme for the integrated management of potato-peach aphid, Myzus persicae (sulzer). Different treatments including, Imidacloprid 25 % WP, Tracer 240 EC, Acetamaprid 20 SP, Potato berseem mixed cropping with or without yellow sticky plastic sheet and Potato + Yellow traps were evaluated for their effectiveness. Among all the treatments mixed cropping of potato and berseem together with or without yellow sticky plastic sheet traps was found most effective in reducing the population density of M. persicae i.e. 1.92 aphid per potato leaf and culminated in enhancing the number of associated natural enemies of M. persicae per potato comprising ladybird beetle (9.06), syrphid fly (4.18), green lacewing (8.80), parasitoid mummies (8.18). Also highest yield (12.42 tones per ha) was recorded from the same treatments. Imidacloprid 25% WP, Acetamaprid 20 SP and Tracer 240 EC were ranked next to potato berseem mixed cropping (with or without yellow traps) in reducing the population density of M. persicae to 2.01, 2.01 and 2.07 aphid per potato leaf, respectively. Imidacloprid 25% WP, Acetamaprid 20 SP and Tracer 240 EC had almost similar effect on the number of natural enemies and on the yield of potato crop.
