Snake gourd, Trichosanthes anguina L., is a yearly climber in the family cucurbitaceae has huge health benefits against blood pressure, heart disease, rheumatism and psoriasis. Fruit flies (Tephritidae: Diptera) are one of the most interesting group of insects also called it as ‘peacock flies’ due to their habit of vibrating their wings and rank among the world most serious pest in cucurbit ecosystem. It infests nearly 70 host plants; among these snake gourd, bitter gourd, muskmelon and snap melon are the most preferred host. Apart from insecticide spray, traps are important tool for the monitoring and mass trapping of fruit flies. Vegetable growers find difficulties in purchasing the commercial traps because of its cost and local availability. Hence, in order to provide the better management of fruit flies the present investigation was focused on developing cost effective cum easily available traps with maximum trapping efficiency. The experiment was conducted in farmer’s field at Kumaravadi village, Tiruchirappalli during January to March 2020. Totally seven numbers of traps were designed and taken for evaluation along with standard bottle trap as check. To assess the dynamics of Z. cucurbitae and B. dorsalis both the lures viz., cue lure and methyl eugenol were placed in trap designs and the population of trapping was recorded periodically. The finding indicated that the bottle trap half cut model was identified as the good design in fruit fly trapping with the mean catches and trapping efficiency of 16.39 fruit flies/trap/week and 19.67-24.10 followed by vertical cylindrical trap (13.94 fruit flies, 17.05-19.88%), horizontal cylindrical trap (11.83 fruit flies, 15.08-16.27%), cylindrical bucket trap (9.89 fruit flies, 12.70-13.39%) and standard bottle trap (8.22 fruit flies, 10.24-11.48%) in cue lure material. Likewise, in methyl eugenol attractant, bottle trap half cut model trapped more fruit flies (15.28 numbers) followed by vertical cylindrical trap (12.83 numbers), horizontal cylindrical trap (10.61 numbers), cylindrical bucket trap (8.50 numbers) and standard bottle trap (6.67 numbers) with the trapping efficiency of 21.54-28.03%, 18.85-21.97%, 16.15-16.67%, 12.12-13.46% and 9.09-10.68%, respectively. The minimum numbers of fruit fly catches were observed in bottle trap two opening model with the trapping efficiency of 7.83-9.51% and 6.82-8.46%, coconut shell trap (5.42-7.87% and 3.79-6.54%) and bulb trap (3.01-6.23% and 1.52-4.62%). The hierarchy of varied designs on trapping efficiency is in the order of bottle trap half cut model > vertical cylindrical trap > horizontal cylindrical trap > cylindrical bucket trap > bottle trap two opening model > coconut shell trap > bulb trap. The trapped fruit flies in designed traps were significantly had a positive correlation with minimum and maximum temperature, wind speed, rainfall and negative with relative humidity.
