Abstract: Three pre adult fitness parameters namely fecundity, rate of development and egg to adult -viability were analysed in three geographic strains of Drosophila nasula nasula at constant (20°C & 25°C) and at ambient temperatures. In most of the cases, the fitness of My (Mysore) strain was found to be significantly higher than rest of the two Among the remaining wild types viz., Sy-l and Sy-ll (Seychelles Islands, Africa), the latter was found to have Significantly higher fitness than the former in most of the instances. Thus the results show that there are intraspecific variations with respect to their fitness parameters.
