Abstract

By analyzing the mating activity of newly isolated yellow and sepia mutants of Drosophila willistoni no difference in behavior between sepia and wild-type flies were observed, whereas yellow males were less successful than wild-type males when competing for females. These results are in agreement with those reported for other Drosophila species. D. willistoni was different in the 'females-competing' crosses because wild-type males mated more frequently with wild-type females whereas yellow males mated successfully with both phenotypes. These results indicate the complexity of the courtship behavior in D. willistoni and provide data for comparative and evolutionary research into the genus.

摘要

通过分析新分离出的威氏果蝇黄色和乌黑色突变体的交配行为，未观察到乌黑色突变体与野生型果蝇在行为上有差异，而在争夺雌性果蝇时，黄色雄性果蝇不如野生型雄性果蝇成功。这些结果与其他果蝇物种的报道一致。在“雌性竞争”杂交中，威氏果蝇有所不同，因为野生型雄性果蝇与野生型雌性果蝇交配更频繁，而黄色雄性果蝇与两种表型的雌性果蝇都能成功交配。这些结果表明了威氏果蝇求偶行为的复杂性，并为该属的比较研究和进化研究提供了数据。
