The hypothesis that adaptation to local environments can increase mating success was tested using ten replicate lines of Drosophila melanogaster adapted either to 16 degrees C or to 25 degrees C. Competitive mating trials at both temperatures were performed with males taken from a pair of lines, one adapted to each temperature. There was no average increase in mating success for males adapted to the local environment. Although one pair of lines showed the expected pattern, another pair showed the reverse pattern. More data are needed on this hypothesis, preferably with lines that have more strongly adapted to local environments.
假设适应当地环境可以提高交配成功率，使用经过 16°C 或 25°C 适应的十个重复的黑腹果蝇（Drosophila melanogaster）品系进行了测试。在这两个温度下，使用从一对适应于每种温度的品系中取出的雄性进行了竞争性交配试验。适应于当地环境的雄性的交配成功率没有平均提高。尽管一对品系表现出预期的模式，但另一对品系则表现出相反的模式。需要更多关于这个假说的数据，最好是使用对当地环境适应更强的品系。
