Drosophila is an excellent organism to test Ayurvedic medicines. The objective of our study was to explore the potential of Emblica officinalis drug on longevity, sexual behavior, and reproductive fitness of Drosophila melanogaster using adult feeding method. Increase in the lifespan, fecundity, fertility, ovarioles number, and developmental time was observed in both parents and F1 generation, but not in the F2 generation in experimental culture (control + E. officinalis). According to the Duncan's multiple range test and ANOVA, there is a significant difference between two cultures. It was also noticed that E. officinalis influence some fitness characters in Drosophila along with sexual behavior.
