Impact of yellow sticky trap against brinjal white fly (Bemesia tabaci) with recommended dose of fertilizer and seed, soil and micronutrient treatment was investigated through Front Line Demonstration in Malda of West Bengal during kharif season of 2019-20 and 2020-21. The demonstration yield were 292.44q/ha and 305.54q/ha which were 18.34% and 30.26% higher to control (248.33q/ha and 236.43q/ha) during respective years. The mean little leaf and stunted growth were10.13% and 8.9%in demonstration and 64.73% and 58.49% in control. Net return and benefit-cost ratio from demonstration were Rs. 2,55,329/-ha and 2.75 during 2019-20and Rs. 2,73,020/-ha and 2.84 during 2020-21 and Rs. 1,72,421/-ha and 1.50 in 2019-20and Rs. 1,52,943/-ha and 1.26 in 2020-21 in control. The extension and technology gaps were 44.11q/ha and 57.56q/ha in 2019-20and 69.11q/ha and44.46q/ha in 2020-21.Reduction of technology index from 16.45% (2019-20) to 12.70% (2020-21) exhibited feasibility and acceptability of installation of yellow sticky traps against whitefly in brinjal in these areas.
