Two components of mating behavior, mating latency and duration of copulation, were investigated in Drosophila melanogaster males from three different ..nutritional.. strains, reared for more than 35 generations on banana, tomato and cornmeal-agar-yeast substrates. Males from different strains did not differ according to mating latency and duration of copulation. Also, the sizes of males from different strains did not contribute to these behavioral traits.
