The initial infestation of aphids begins at 55 DAS (Days after sowing) on sole crop while 85 DAS on intercrops. Highest infestation is obtained at 95 DAS on all rows of sole crop (mustard). Intensity of aphid was greatest on mustard-chickpea followed by mustardwheat, mustard-coriander and the lowest on mustard-fennel with greater yield.
