Abstract

Courtship time, duration of copulation and fertility were tested in six wild type strains of <i>D</i>. <i>ananassae </i>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 fe rtility in <i>D. ananassae.</i>
