Abstract

The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University of Bangladesh during the period from October, 2019 to March, 2020 to evaluate the ecofriendly management of cucurbit fruit fly (Bactrocera  cucurbitae) in bitter gourd. Seven treatments such as; Pheromone trap, Vinegar trap, Sweet gourd bait trap, Banana bait trap, Neem seed extract, Datura seed extract and Untreated control were used in the field. The experiment was laid out following Randomized Complete Block Design with three replications. The highest yield increase (183.27%), fruit length (38.30%) & girth (97.86%), number of fruits per plant (156.67%) was achieved by Sex pheromone trap. The highest yield (23.03 ton/ha) was also achieved by Sex pheromone trap followed by 22.16 ton ha-1 in Sweet gourd bait trap. Sex pheromone trap also showed similar performance in terms of weight of single fruit, length of fruit, girth of fruit and yield. It also reduced the fruit infestation. Considering the results of the present study, it can be concluded that the Sex pheromone trap may be used for the management of cucurbit fruit fly in bitter gourd.
