The Effects of Ethanol on Courtship and Mating Preference in Drosophila melanogaster

In this paper the author tested the effect of ethanol consumption on Drosphila's courtship patterns and fecundity rate. Virgin males are separated into two groups; one getting food with water and one made with ethanol. Food consumption was highly regulated for 4 days. After four days males were combined with virgin females. They observed a significantly shorter courtship period, but a significant higher fecundity rates for flies with ethanol exposures. Flies also prefered ethanol food significantly to water food.
