Abstract
This study was conducted to determine diversity and distribution of true flies in Bohol and Mindanao, Philippines. Malaise traps were used to collect samples in different habitats. A total of 104 presumptive species of dipterans were identified based on the number of Molecular Operational Taxonomic Units (MOTUs) clustering at 3% threshold. The results showed that diversity of presumptive species of dipteral is higher in Bohol compared to Mindanao with species diversity indices, H’=3.70 and H’=3.26, respectively. The observed difference may be influenced by the heterogenous habitat between sampling sites and the longer periods of sampling. Further, DNA barcodes were then mapped using QGIS. The result showed that 87.5% of the presumptive species belonging to eight families of Diptera were found only in Magsaysay Park, Bohol. These include: Culicidae, Dolichopodidae, Empididae, Mycetophilidae, Sepsidae, Stratiomyidae, Tabanidae, and Tephritidae. This is possibly due to the unique characteristic of habitat in Magsaysay Park, Bohol, hence, a key site for conservation.
