Significant interspecific variations in mean duration of copulation and fertility were observed in four species of the Drosophila bipectinata species complex. However, D. bipectinata showed positive correlation between duration of copulation and fertility. Similarly, D. malerkotliana showed negative correlation between mating latency and duration of copulation. Likewise, D. pseudoananassae showed positive correlation between mating latency and fertility. These results suggest that D. pseudoananassae has distant relatedness from the other three species with respect to mating latency, duration of copulation and fertility which supports the previous findings.
在果蝇双栉角果蝇种组的四个物种中观察到交配平均持续时间和生育力存在显著的种间差异。然而，双栉角果蝇的交配持续时间和生育力之间呈正相关。同样，马勒科特利亚纳果蝇的交配潜伏期和交配持续时间之间呈负相关。同样，拟暗果蝇的交配潜伏期和生育力之间呈正相关。这些结果表明，就交配潜伏期、交配持续时间和生育力而言，拟暗果蝇与其他三个物种的亲缘关系较远，这支持了先前的研究结果。
