Abstract:
The experiment was carried out in the central farm of Sher-e-Bangla
Agricultural University, Sher- e-Bangla Nagar, Dhaka to find out biorational
management of cucurbit fruit fly on sweet gourd by using some new generation
insecticides during rabi season from November, 2019 to April, 2020. There
were five treatments viz, T
1
=Fytomax 3 EC @ 1 ml/L of water, T
2
= Pheromone
trap (Cuelure) + Success 2.5 SC @ 650 ml/ha, T
3
= Bait trap + Success 2.5 SC
@ 650 ml/ha, T
4
= Ripcord 10 EC @ 1 ml/L of water (Farmers’ practice), T
5
=
Untreated control. All treatments were applied at 7 days interval. The experiment
was laid out in Randomized Complete Block Design (RCBD) with three
replications. Among the treatments, Pheromone trap (Cuelure) + Success 2.5
SC @ 650 ml/ha showed the best performance in controlling cucurbit fruit fly.
The highest yield (37.44 t/ha), the healthy fruits (34.21 t/ha) and lowest
infested fruit (3.23 t/ha) were obtained from the treatments T
2
followed by
treatments T
1.
The lowest percent fruit yield (18.37 t/ha) healthy fruit (12.04),
and highest infested fruit (6.33 t/ha) were obtained from T
5
(untreated control).
The use of Pheromone trap (Cuelure) + Success 2.5 SC could be effectively
utilized in the cucurbit fruit fly management.
