Intra- and interspecific preadult competition studies were made among the three abundant and sympatric species namely Drosophila malerkotliana, Drosophila bipectinata and Drosophila nasuta nasuta. Rate of development and viability were used as fitness components in both pure cultures (intraspecific competition) and in mixed cultures (interspecific competition) at different densities. Considering the rate of development and viability together, D. malerkotliana, D. bipectinata and D. n. nasuta behave differently in intra- and interspecific preadult competition. During interspecific competition irrespective of densities, D. malerkotliana shadows the other two competitors both in rate of development and viability. On the other hand D. n. nasuta is a weak competitor. Thus, based on preadult competition the sequence can be depicted as D. malerkotliana > D. bipectinata > D. n. nasuta.
