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

trap with banana mashed at 5 days interval; T

= Using bait trap with sweet gourd mashed
at 5 days interval; T

days interval; T

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.
