Abstract: The present investigation was on the role of Dietary restriction in the lifespan of different species of Drosophila. Drosophila melanogaster, Drosophila nasuta nasuta and Drosophila nasuta albomicans were included in the study. Different combinations of diet were supplemented along with the standard wheat cream agar media in variable doses. Drosophila will be maintained at room temperature 22 ± 1°C with a relative humidity of 70%. Further following assessments were carried out. In this study, dietary restrictions (essential amino acids, proteins and carbohydrates) were evaluated for Lifespan in Drosophila species. As there is a decrease in longevity of control flies, one can assume that the additional dietary nutrients have an impact on extending lifespan. In addition to this irrespective of diet and concentrations the females have shown increased lifespan than males. The present investigation claims that protein plays essential role than carbohydrates or amino acid in determining the lifespan of Drosophila species. Further detailed study needed on the molecular impacts of Dietary restriction in Drosophila.
