abstract
The studies were conducted to screen Indian bean, Lablab purpureus var. typicus (L.) sweet varieties for resistance against major sucking insect pests viz., aphid, Aphis craccivora (Koch); leafhopper, Empoasca fabae (Harris) and whitefly, Bemisia tabaci (Genn.) during kharif, 2019. The experiment was laid out in randomized block design with eight varieties each replicated thrice. The observations on the population of major sucking insect pests were recorded soon after appearance on all the varieties at weekly interval. Out of eight varieties of Indian bean screened for relative resistance against sucking insect pests, none was found free from the infestation of pests. The varieties Pusa Early Prolific and Arka Jay were categorized as highly resistant to leafhopper and whitefly whereas, Arka Jay and Pusa Early Prolific to aphid. The varieties Pariry, Bauni, G. Local and Diana were categorized as moderately resistant and J. K. SPL and K. Bhusan were categorized as least resistant to aphid, leafhopper and whitefly. The total phenols had significant negative and free amino acid had significant positive effect on the population of sucking insect pests on Indian bean.
