Abstract:
A field experiment was conducted at Sher-e-Bangla Agriculture University farm to find out
effect of different traps on incidence and management of cucurbit fruit fly, Bactrocera
cucurbitae during November 2012 to April 2013. The treatments of the experiment were T1
= Pheromone Trap (Plastic pot), T2 = GME pheromone water Trap, T3 = Sticky Trap, T4 =
Bait Trap, T5 = Funnel pheromone Trap, T6 = Light Trap, T7 = Bait Trap+ Pheromone
Trap (Plastic pot) and T8 = Untreated control. The experiment was laid out in
Randomized Complete Block Design (RCBD) with three replications. Results
showed that, T7 (Bait trap + pheromone trap (plastic pot)) was the most effective
treatment for early (1.88), mid (3.00), late (1.92) fruiting stages and total (6.80) cropping
period in terms of adult trapped/plot and no adult was caught in T8 (Control plot), T3
(Sticky trap) and T6 (Light trap). Bait trap in combination with Pheromone trap
(plastic pot) (T7) gave the best result for total number of healthy fruits/plot (6.33),
highest per cent increase of yield by number (111.11%), weight of healthy fruits/plot
(8.61kg) and per cent increase of yield by weight (438.9%). Funnel pheromone trap
(T5) also showed similar result and intermediate result was found in T1 (Pheromone
trap (plastic pot)), T4 (Bait trap) and T2 (GME water pheromone trap). The lowest
number of healthy fruits/plot (3.00/plot) and healthy fruit weight (1.64 kg/plot) was
obtained from control plot. T3 (Sticky trap) and T6 (Light trap) had no effect on capturing
adult fruit fly and gave the similar yield to control. Pheromone trap (plastic pot) in
combination with Bait trap may be used for the management of fruit fly attacking
cucurbitaceous vegetables.
