Zaprionus indianus (Gupta, 1970) (Diptera Drosophilidae), also known as African fig fly, isconsidered as the primary pest only to fig fruits along with secondary pest to other fruits. Its oc-currence has been reported from many countries but not previously reported from Bangladesh.With this note, we report here the first observation of Z. indianus from Bangladesh. Fly sampleswere collected by using yeast-banana traps. The species was identified by morphological char-acteristics and mitochondrial COI gene sequence.

Nisaetus bartelsi is a native hawk from Java which its genetic information is not commonly understood yet. As a part of the conservation effort to maintain genetic diversity of this endangered species, this research aimed to obtain COI gene sequences from five individuals of N. bartelsi to confirm its position in the phylogenetic tree. DNA isolation from 5 N. bartelsi blood sample was performed and its COI gene sequence was amplified, sequenced, and used to reconstruct phylogenetic tree using MEGA6 with several other members of Nisaetus, Aquila, and Saggitaridae family. Furthermore, the intraspecific distance between 5 N. bartelsi samples and interspecific distance with other species were calculated using MEGA6. The result suggested that all five individuals belonged to the species Javan hawk-eagle (N. bartelsi) and were closely related to the Blyth’s hawk-eagle (Nisaetus alboniger). The DNA barcoding of the Javan hawk-eagle conducted in this study is a stepping stone to conservation efforts for the Javan hawk-eagle.

Flies are considered serious pests which cause health problems of human and animal, transmitting many pathogenic microbes. Pest management programs depend on proper identification of pests. The present research work is an initiative to identify the medically and veterinary important flies based on mitochondrial COI gene sequences. Eleven species of the fly pests were identified. Among them, four fly species were the first record from Bangladesh. The phylogenetic analysis of retrieved sequences confirmed that the evolution of these species occurred from a common ancestor. Highest AT percentage (69.9%) was found in Haematobia irritans exigua and lowest GC percentage (30.4%) was found in Haematobia irritans exigua. The substitution rate of codon was found 1.88 in 1st position, 0.73 in 2nd position and 1.22 in 3rd position, respectively. Interspecific genetic divergence range of flies sequences was 5-20%. Haplotype network showed that Atylotus agrestis was mostly diverged from its common ancestors by 37 mutational steps. This research is the first molecular approach to identify the medically and veterinary important flies based on MT-COI gene sequences along with the establishment of first DNA barcode dataset for accurate identification in Bangladesh.
