Abstract

The results revealed that the incidence of aphid infestation was significantly higher in sole cropping systems as compared to intercropping systems. The diversified cropping systems T1, T2, T3 and T4 were observed to show minimum aphid infestation in the range of 0.15 -0.77, 0.14 -0.80, 0.13 -0.80 and 0.15 - 0.76 mean aphid colonies/plant, respectively, as compared to sole cropping systems T5, T6, T7 and T8 with mean aphid infestation in the range of 1.40 -4.96, 2.83 -5.30 and 1.73 to 5.53 mean aphid colonies/plant, respectively throughout the growing season. The diversified cropping systems were also observed to inhabit more number of Coccinellid beetles as compared to sole cropping systems.
