The investigations on the “Bio-efficacy of newer insecticides and biopesticides against fruit fly, Bactroceracucurbitae (Coquillett) on round gourdˮ were carried out at Horticultural farm of SKN college of agriculture, Jobner, Jaipur during Summer, 2016. Among the insecticides evaluated against fruit fly on round gourd, spinosad was found most effective. The next effective treatments were acephate + molasses followed by acephate and fipronil. The treatments of Neem Gold and NSE were found least effective. The maximum marketable yield of round gourd fruits was obtained in spinosad (105.14 q ha-1) followed by acephate + molasses (102.57 q ha-1) whereas; minimum (50.12 q ha-1) was in NSE. The maximum net profit of Rs. 90956 ha-1 was obtained in treatment of acephate + molasses, whereas, minimum net profit of Rs. 13176 ha-1 was in NSE. The highest benefit cost ratio was computed in acephate (59.41), while the minimum was in Neem gold (5.54).
