Drosophila melanogaster Laboratory Rearing for Wolbachia -Based Control Programs, a Component of Dengue Control.

Background: Drosophila melanogaster flies are smooth, low upkeep and safe model organisms, they can be effortlessly used in different fields of life sciences like genomics, biotechnology, genetics, disease model, and Wolbachia -based approaches to fight vectors and the pathogens they transmit.
Methods: Fruit fly specimens were collected in 25 districts (14 provinces) of Iran and their morphological recognition was proven by molecular analysis based on sequence homology of mitochondrial COI barcode region. Essential information and specific requirements w ere provided for laboratory rearing of D. melanogaster .
Results: Drosophila melanogaster colonies were found in 23 out of 25 districts. Also, five related species coincident with D. melanogaster were reported in this study including D. ananassae/D. parapallidosa , D. hydei, D. repleta , Zaprionus indianus (Diptera: Drosophilidae), and Megaselia scalaris (Diptera: Phoridae). The Iranian D. melanogaster molecular signature and their rearing techniques have been described here. The complete life cycle, from (egg to adult), takes approximately 8 days at 25 °C. Some biological points have been presented with highlighting capturing, rearing, culturing, and embryo collection along with primitive recognition and segregation between females and males have been presented. A recipe for culture media and the quantity of various ingredients have been provided.
Conclusion: This is the first report on the D. repleta and D. ananassae/D. parapallidosa species for the country. Results of this study provide efficient and effective rearing procedures which are requirement for both small-scale for facilitating entomological research and large-scale use in justifiable vector control management such as disease model or Dengue control.
