EFFECTIVENESS OF DIFFERENT PHEROMONE-TRAP DESIGNS FOR MANAGEMENT OF CUCURBIT FRUIT FLY, BACTROCERA CUCURBITAE (Coquillett)

Abstract

A field experiment was conducted at Sher-e-Bangla Agricultural University farm to find out the effectiveness of different pheromone-trap design for management of cucurbit fruit fly during January to July 2012. The treatments of the experiment were, T1 = Pheromone trap (Conventional ), T2 = Pheromone trap with adhesive, T3 = Pheromone trap with funnel, T4 = Pheromone trap with adhesive + Bait trap, T5 = Pheromone trap with funnel + Bait trap, T6 = Pheromone trap with adhesive + Bait trap + Polybag and T7 = Untreated (Control). The experiment was laid out in a Randomized Complete Block Design with three replications. Among the treatments the Pheromone trap with funnel +Bait trap(T5) showed the best performance in controlling cucurbit fruit fly. Consequently highest yield (38.44 t/ha),highest healthy fruit (35.23 t/ha) and lowest infested fruit(3.21 t/ha) were achieved from the treatment. Also the highest number of fruit fly was trapped in T5 at early,mid and late fruiting stage while lowest performance showed by T1.The performance of Pheromone trap with funnel(T3) was superior to other treatments but significantly lower than T5 treatment. The experiment revealed that pheromone trap with funnel could be effectively utilized in fruit fly management.
