摘要

Experiments were conducted to study rare male mating advantage in two karyotypically different strains of Drosophila ananassae: (a) ST/ST and (b) AL/AL (2L). Mating success of flies of two strains was scored by direct observation in Elens-Wattiaux mating chamber at five different ratios employing multiple-choice technique and two different experimental designs. The results indicate that there is significant one-sided rare male mating advantage in favour of AL males. The same data were analysed for a comparison between number of homogamic and heterogamic matings. With both experimental designs, the homogamic matings are significantly more frequent than heterogamic ones and isolation estimate remains low (0.55-0.62), which shows preferential mating between females and males with the same karyotype. These findings provide an evidence for one-sided rare male mating advantage in favour of AL males and sexual isolation between karyotypically different strains of D. ananassae.
