Abstract
Mating propensity and fertility were studied in five laboratory strains of Drosophila ananassae which were established from single females collected from different geographical localities. The results show statistically significant variation among different isofemale lines with respect to mating propensity and fertility. The strains showing greater sexual activity produce more progeny. Thus, there is a positive correlation between mating activity and fertility in D. ananassae. The comparison of mating frequencies of strains and their hybrids reveals the existence of heterosis and reciprocal effects. The data suggest that the males are more subject to intrasexual selection.
