Abstract: The present study was conducted to assess the Study of the Integrated Pest Management practices against bitter gourd fruit fly in District Jaunpur (U.P.) India. The demonstration was conducted at farmers fields in two village viz. Alhadiya and Meerganj of the district Jaunpur (U.P.) during Kharif season 2016 and 2017. Technological gap between recommended practice and actual farmers practice was observed that respondents were small holding (0.5 to 1.25 ha). Out of 100 farmers10 were selected randomly for field experiments. The treatment was growing of maize as border crop + Installation of cue-lure with Novaluron (4:1) + Spraying of NSKE 5% + Spraying of Flubendiamid 39.35 EC @ 0.3 ml/ lit of water. Overall technology gap of 41.60% was recorded whereas 43.29% gap in overall IPM practices observed. The marketable yield were recorded significantly higher in IPM plot 21.36 tone and 22.24 tone ha^-1 as compared to farmer practice 14.03tone and 14.92tone ha^-1 during kharif 2016 and 2017.The loss of yield due to fruit fly were higher in control plot. The population of fruit fly was recorded lower in IPM plot (1.83 and 1.78 larvae/plant) than control plot (5.12 and 4.92 larvae/plant). Benefit cost ratio of 7.96 and 8.18 was calculated in IPM bitter gourd in Kharif 2016 and 2017 season respectively in comparison to control plot.
