Efficacy of Different Traps for Controlling Cucurbit Fruit Fly, Bactrocera Cucurbitae (COQ) on Host Bottle Gourd, Lagenaria Siceraria

The experiment was conducted in the experimental field of the Sher-e-Bangla Agricultural University, Dhaka during the period from October, 2017 to March, 2018 to evaluate efficacy of different traps for controlling cucurbit fruit fly, Bactrocera cucurbitae (coq) on host bottle gourd, lagenaria siceraria in Bangladesh, using variety �BARI-Lau 1�, Sher-e-Bangla Agricultural University, Bangladesh. Treatments for the management were T1 = Pheromone Trap, T2 = Bait trap with sweet gourd mashed, T3 = Vinegar with rotted fruit trap, T4 = Bait trap with banana mashed, T5 = Funnel pheromone Trap, T6 = Sticky board trap, T7 = Untreated control and laid out in a Randomized Complete Block Design (RCBD) with three replications. The highest adult captured in T5 (Funnel Pheromone trap) at different days interval, whereas the lowest (3.07) was captured in T6 (Sticky board trap) and no adult was caught in T7 (untreated control) treatment. Considering the all yield attributing characteristic, such as percent healthy and infested fruits by both weight and number, percent infestation over control, total yield, the treatment T5 showed the best performance for controlling of the B. cucurbitae among all the treatments. T1 showed the second highest performance, whereas, T6 showed the lowest performance. The lowest total fruit yield (57.32 t/ha) was obtained in T7, followed by T6 treatment during the cropping season of bottle gourd.
