Ethanol levels in Drosophila breeding sites in seepages of unfortified wine inside wineries have been found to be similar to those in many decaying fruits and vegetables. Fortified wine seepages inside wineries have ethanol levels on average three times as high as other breeding sites. However there was no evidence that this variation in ethanol levels was associated with differences in Adh frequencies in D. melanogaster at sites either within wineries or outside wineries. D. simulans was at lower frequencies at sites inside wineries compared to sites outside although this difference may not be related to ethanol levels. It is concluded that adaptation to natural levels of environmental ethanol by D. melanogaster does not necessarily modify Adh frequencies.
在酿酒厂内未强化葡萄酒渗漏处的果蝇繁殖地，乙醇水平已被发现与许多腐烂水果和蔬菜中的乙醇水平相似。酿酒厂内强化葡萄酒渗漏处的乙醇水平平均是其他繁殖地的三倍。然而，没有证据表明乙醇水平的这种变化与酿酒厂内外不同地点黑腹果蝇的乙醇脱氢酶（Adh）频率差异有关。与酿酒厂外的地点相比，拟果蝇在酿酒厂内地点的频率较低，尽管这种差异可能与乙醇水平无关。得出的结论是，黑腹果蝇对环境乙醇自然水平的适应不一定会改变乙醇脱氢酶频率。
