    The present studies on the “Evaluation of different traps and lures for management of fruit fly on pumpkin crop ” were conducted in the Department of Entomology, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya, during 2020-21. Significant variation in occurrence of the fruitfly was recorded during the period of investigation. Trapping of fruit fly was started from 9 SMW and continued up to 25 SMW by using sex attractant, cuelure and methyl eugenol . Incidence of B. zonata and B.dorsalis, was high (48.75 fruit flies/trap/week) and (38.41 fruit flies/trap/week) respectively on 21 SMW caught by methyl eugenol and the incidence of B. cucurbiteae and B.tau, was high (33.41fruit flies/trap/week) and (18.00 fruit flies/trap/week) respectively on 20 SMW caught through cue lure. Correlation between mean population of B. zonata, B.dorsalis showed highly significant positive correlation with minimum temperature and maximum temperature, while the relative humidity showed significantly with negative correlation and rainfall showed non significantly negative correlation respectively and B. cucurbiteae , B. tau population showed non-significantly positive correlation with minimum temperature and significantly positive correlation with maximum temperature however it was significantly negative correlated with relative humidity and non-significantly negative correlated with rainfall respectively in Zaid season of 2020. In the study of efficacy of methyl eugenol and cue lure found that highly capturable and effective sandard dose was Methyl eugenol+ malathion (1.5 ml +2ml) caught 69.39 fruitflies (Bactrocera dorsalis + Bactrocera zonata) and cuelure+ malathion (2ml+2ml) standard dose caught 19.92 fruitflies (Bactrocera cucurbiteae + Bactrocera tau).In the study of life cycle of fruitfly pre-oviposition period, oviposition period, fecundity number of egg/female/life, incubation period (hour), larval period, pupal period, male longevity, female longevity was recarded 13 ±2 days,18.5 ±5 days, 227.5 ±27.5, 1.25 ±0.25 hours , 12.5 ±0.5 days, 9 ±1 days, 18.5 ±1.5 days and 24.5 ±3.5 days respectively. In the study of yield estimation trapping with cuelure+ malathion (2ml+2ml) standard dose given highest yield (236 q/ha) and cast benefit ratio (1:65.0). The minimum yield produced in control (144 q/ha).
