MANAGEMENT PRACTICES FOR FRUIT FLY AND FRUIT WEEVIL OF MANGO AT BANDARBAN, RANGAMATI AND KHAGRACHARI DISTRICTS

Abstract

The present study was conducted at the farmer’s orchard in Bandarban, Rangamati and Khagrachari districts, during the period from January to July, 2016 to develop management options against mango fruit fly and fruit weevil. The treatments of the experiment were T1 = application of Ripcord 10EC 4 times, T2 = application of Ripcord 10EC 5 times, T3 = application of Ripcord 10EC 4 times + pheromone trap, T4= 5 times application of Ripcord 10EC + pheromone trap, T5= 4 times application of Ripcord 10EC + pheromone trap + bait trap, T6 = 5 times application of Ripcord 10EC + pheromone trap + bait trap and T7 = untreated control. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The lowest percent of fruit infestation (6.88%, 6.99% and 5.72% at Bandarban, Rangamati and Khagrachari, respectively) was observed in T4 as against the highest percent fruit infestation (83.68%, 88.58% and 86.12% at Bandarban, Rangamati and Khagrachari, respectively) was found in T7. Treatment T4 gave maximum protection of fruit infestation (91.77%, 92.10% and 93.36% at Bandarban, Rangamati and Khagrachari, respectively) over control and produced higher amount of healthy mango fruits/tree. Treatment T6 consisting spraying Ripcord 10EC @ 1.0 ml/L water 5 times + pheromone trap + bait trap and T5 spraying Ripcord 10EC @ 1.0 ml/L water 4 times + pheromone trap + bait trap also showed the similar performance for the management of mango insect pests. Among seven treatments T4 comprising spraying of Ripcord 10EC @ 1.0 ml/L of water 5 times + pheromone trap was the most effective management practice and may used for the management of mango fruit fly and fruit weevil.
