title: Mating activity and fitness of a few wild type strains of Drosophila ananassae.
abstract: Courtship time, duration of copulation and fertility were tested in six wild type strains of D. ananassae originating from different geographical localities. The results indicate that there is significant variation among the strains tested with respect to courtship time, duration of copulation and fertility. The strains showing a longer duration of copulation produce more progeny. These findings suggest that there is a positive correlation between duration of copulation and fertility in D. ananassae.
