Abstract Mango (Mangifera indica L.) is a major fruit crop throughout the tropical and sub-tropical regions of the world including Bangladesh. The Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) is a major pest of mango causing both quantitative and qualitative losses as well as export barriers. We compared the efficacy and economic benefits of several prophylactic and remedial tactics against B. dorsalis during the 2017 mango cropping season in pursuit of the development of a mango IPM program to produce fruit fly-free and residue-free mango fruits. Several non-chemical approaches, such as bagging fruits with double-layer brown paper bags, cloth bags, polythene bags, and installing methyl eugenol kairomone traps and protein hydrolysate bait lures, were evaluated and compared with conventional Profenofos + cypermethrin (Shobicron 425 EC) management. Among the treatments, bagging mangos with double-layer brown paper bags at forty-two days before harvest showed the best performance. Fruit infestation was reduced to zero, marketable yields were significantly higher than with conventional pesticide management, and the marginal benefit cost ratio of bagging mangos with double-layer brown paper bags was nearly twice as high as any other treatment. The strong economic return from bagging fruits with double-layer brown paper bags results from high fruit quality and being able to use the bags for two growing seasons. The positive results from this study indicate that double-layer brown paper bagging is effective at controlling the oriental fruit fly in mango and should be integrated into a full IPM package for mango production.

孟加拉国针对芒果果蝇（Bactrocera dorsalis Hendel）的生物理性管理方法比较

摘要 芒果（Mangifera indica L.）是世界热带和亚热带地区包括孟加拉国在内的主要水果作物。东方果蝇 Bactrocera dorsalis (Hendel)（双翅目：实蝇科）是芒果的主要害虫，造成数量和质量损失以及出口障碍。我们在 2017 年芒果种植季节比较了几种针对 B. dorsalis 的预防和补救策略的功效和经济效益，以寻求开发芒果 IPM 计划以生产无果蝇和无残留的芒果果实。几种非化学方法，例如用双层牛皮纸袋、布袋、聚乙烯袋装袋水果，并安装甲基丁香酚kairomone陷阱和蛋白质水解物诱饵诱饵，进行了评估并与传统的 Profenofos + 氯氰菊酯 (Shobicron 425 EC) 管理进行了比较。各处理中以收获前42天双层牛皮纸袋装袋芒果表现最佳。果实侵染减少到零，适销对路产量显着高于常规农药管理，双层牛皮纸袋装袋芒果的边际效益成本比几乎是任何其他处理的两倍。使用双层牛皮纸袋装袋水果可带来强劲的经济回报，原因在于水果质量高，并且能够在两个生长季节使用这些袋子。
