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.

Taxonomic identification of flies having medical and veterinary importance is often complicated due to the lookalike morphological characters. Molecular identification of five Indian muscid flies (Musca domestica, Musca sorbens, Musca crassirostris, Stomoxys calcitransand Haematobia irritans) has been attempted on the basis of mitochondrial COII gene.Sequences of 500-520 bp were analysed and found to be A+T rich. Rate of transitions was higher than transversions. The average haplotype diversity was 0.833 and nucleotide diversity was 0.02547 within the different species, which were calculated with the DnaSP Version 5.0. The genetic distances calculated by K2P model, showed the interspecific distances range more than 8.2%, while the intraspecific distance range had not exceed 0.8%. The 1000 bootstrapped Neighbour-joining tree and Maximum likelihood tree were constructed to establish the phylogenetic relationship between the different muscid species.

The data obtained from this study would be worthy for medical and veterinary entomologists for precise identification of imperative muscid species.

“…Both species have proven to be highly invasive and have often been classified as subspecies . It is hard to discriminate between them morphologically, whereas at the molecular level, ribosomal genes are conserved, and mitochondrial genes have a relatively low divergence of 1.8–1.9% . The estimated cost of HF and BF to cattle production worldwide is more than US $3.6 billion per annum .…”

BACKGROUND: Haematobia spp., horn flies (HF) and buffalo flies (BF), are economically important ectoparasites of dairy and beef cattle. Control of these flies relies mainly on treating cattle with chemical insecticides. However, the development of resistance to commonly used compounds is compromising the effectiveness of these treatments and alternative methods of control are required. Wolbachia are maternally transmitted endosymbiotic bacteria of arthropods that cause various reproductive distortions and fitness effects, making them a potential candidate for use in the biological control of pests. The first step towards this is the establishment and adaptation of xenobiotic infections of Wolbachia in target host cell lines.RESULTS: Here, we report the successful establishment of a continuous HF cell line (HIE-18) from embryonic cells and its stable transinfection with Wolbachia strains wAlbB native to mosquitoes, and wMel and wMelPop native to Drosophila melanogaster. HIE-18 cells were typically round and diploid with ten chromosomes (2n = 10) or tetraploid with 20 chromosomes (4n = 20), with a doubling time of 67.2 h. Wolbachia density decreased significantly in HIE-18 cells in the first 48 h of infection, possibly due to overexpression of antimicrobial peptides through the Imd immune signalling pathway. However, density recovered after this time and HIE-18 cell lines stably infected with the three strains of Wolbachia have now each been subcultured more than 50 times as persistently infected lines.CONCLUSION: The amenability of HF cells to infection with different strains of Wolbachia and the establishment of stable sustaining infections suggest the potential for use of Wolbachia in novel approaches for the control of Haematobia spp. Further, the availability of the HIE-18 cell line will provide an important resource for the study of genetics, host-parasite interactions and chemical resistance in Haematobia populations.
