The fitness parameter has been studied in Drosophila melanogaster, D. bipectinata,D. malerkotliana and D. ananassae. 7 day aged virgin flies were used for mating experiment, it revealed that, mating latency is more in D. malerkotliana and less in D. melanogaster. Mating time of D. melanogaster is more and it is less in D. ananassae D. bipectinata takes more time to remate and D. melanogaster takes less time to remate. Mating time, fecundity, productivity and viability of virgin is more than mated male in all the species except, D. melanogaster. Even though D. melanogaster has more percentage of viability it takes more time in mating. The mating time is less in D. ananassae whereas, fecundity, productivity and percentage of viability is more than other species.
