A survey on fruit flies in Myanmar was conducted by the Japan International Cooperation Agency (JICA) in collaboration with the national governments of Myanmar and Japan in 2014. The objective of this survey was to acquire information on the Bactrocera fruit fly species present in Myanmar for possible phytosanitary concerns when mangoes are exported to other countries. In the survey, more than seventy thousand Bactrocera fruit fly specimens were collected from four major mango production areas, namely the Yangon, Bago and Mandalay regions and Shan State by fruit sampling and adult fly trapping. The subsequent identification revealed that B. correcta and B. dorsalis were distributed in mango orchards in all four areas. In addition to these, three other species, B. carambolae, B. zonata and B. cucurbitae, were found present while the detected numbers were substantially smaller than the two previously mentioned. While these three species have the potential to infest and damage mango fruits as well, a significantly lower number of flies were caught in each trap per day (FTD) from these three species than the two aforementioned species. In addition, B. zonata and B. cucurbitae were not found in the sampled fruits. Based on this analysis, it was concluded that B. correcta and B. dorsalis are two major species present in mango production areas of Myanmar, and can be of phytosanitary concern to trade partners in the export of mangoes, and other species could be found in commercial mangoes for which further detailed study is necessary.
