The field study on effect of intercropping on population dynamics of major insect pests and vectors of potato revealed that all the treatments viz., T 2=Potato+recommended pesticide schedule of the area, T 3=Potato+Onion in alternative rows (1:1), and T 4=Potato+Garlic in alternative rows (1:1) were statistically superior and significant over control (T 1). Potato along with recommended pesticide schedule was the most effective treatment in reducing the population of cutworm, various defoliators, epilachna beetle, aphid, whitefly and other pests as well as damage caused by the pests.
