Abstract

Two species of Drosophila that differ in their ecology and mating systems have been compared with respect to male contribution to the somatic tissues and developing oocytes of females. In the species Drosophila mojavensis females remate daily, exhibit a copulatory plug, and have been shown to obtain a contribution from the male ejaculate. In contrast, Drosophila melanogaster males do not contribute to females. Female Drosophila melanogaster do not remate as frequently as Drosophila mojavensis females nor is a copulatory plug formed.
