Dose of cue-lure for suppression of melon fly population in pumpkin 

Abstract

Patel Fruit fly Trap (PFT) having Nuwood block (50 x 50 x 08 mm) impregnated with different doses (0.05, 0.10, 0.15, 0.20 and 0.25 ml) of Cue-lure were tested in pumpkin field to decide the optimum dose to suppress population of melon fly, Bactrocera cucurbitae in cucurbit crops. The dose of 0.25 ml Cue-lure remained active for 32 weeks while, the remaining doses attracted male flies up to 30 weeks. The cost of different treatments was computed to be ₹ 12.92, 14.42, 15.92, 17.42 and 18.92 per treatment for 0.05, 0.10, 0.15, 0.20 and 0.25 ml of Cue-lure, respectively. It can be suggested that in long duration cucurbit crops (little gourd, parvar) and other cucurbits (gourd, melons and pumpkin) PFT (10/ha.) impregnated with 0.25 and 0.15 ml of Cue-lure, respectively are suitable for effective and eco-friendly suppression of melon fly, B. cucurbitae population.
