Abstract

Age specific variations in mating, fecundity and reproductive performance occur in many organisms. Drosophila melanogaster represents a good model system for age-related studies and testing direct fitness benefits gained when females mate with specific male phenotypes. However, how male age related changes in male accessory glands and fitness traits are affected by rearing temperatures, has not been examined. Here we examined age-related mating of D. melanogaster in three age classes reared at three different temperatures. In all the rearing temperatures, young males with larger accessory glands containing a small number of large cells produced greater quantity of Acps than old males. Furthermore, young males transferred a greater quantity of Acps and sperms to mated females and as a result females that mated with young males produced significantly greater number of eggs and sperms than female mated with old males. This result was found to be similar in all the three temperatures in D. melanogaster. Together our data indicate that male age related changes in the accessory gland and sperm traits are independent of rearing temperatures
