EVALUATION OF DIFFERENT ECO-FRIENDLY MANAGEMENT PRACTICES AGAINST FRUIT FLY OF BOTTLE GOURD

Abstract

The study was conducted in the experimental field of Sher-e-Bangla Agricultural University , Dhaka during the period from October, 2021 to April, 2022 to find out the evaluation of different eco-friendly management practices against fruit fly of bottle gourd . The experiment was laid out in a Randomized Complete Block Design replicated with three replications. In this study, treatments T 1 ii = Using pheromone trap; T 2 = Using bait trap with banana mashed at 5 days interval; T 3 = Using bait trap with sweet gourd mashed at 5 days interval; T 4 = Using pheromone trap + Using bait trap with banana mashed at 5 days interval; T 5 = Using pheromone trap + Using bait trap with sweet gourd mashed at 5 days interval; and T 6 = Untreated control where nothing were applied. T 5 showed the best performance in terms of number of fruit fly (4.09 adult) captured, percent reduction of fruit infestation by number over control at early (84.50%), mid (77.68%) and late (76.57%) fruiting stages; percent reduction of fruit infestation by weight over control at early (75.43%), mid (72.05%) and late (64.17%) fruiting stages; fruit length (54.87cm), fruit girth (24.37cm), single fruit weight (2.59kg) and yield (71.37t/ha) . The overall study revealed that, the most significant performance was achieved from T 5 treatment (Using pheromone trap + Using bait trap with sweet gourd mashed at 5 days interval) which contributed to highest control of cucurbit fruit fly as well as the maximum increase of healthy fruit length, girth and the yield.
