TI  - Female remating in Drosophila ananassae: evidence for sperm displacement and greater productivity after remating
Y1  - 2001/03//
N2  - ABSTRACT—In Drosophila ananassae, female remating with respect to productivity and sperm displace-ment
was studied by employing different mutant strains and a wild type strain. In all the experiments, the
continuous confinement technique was used. The comparison of productivity between once-mated (control)
and remated females reveals that the productivity of remated females is significantly higher than that of
once-mated ones in all the crosses. The P2´ values (the proportion of second male progeny produced after
remating) were calculated to test sperm displacement in each cross of remated females. In all the crosses,
high P2´ values (0.91–0.94) were found which indicate sperm precedence of second male to mate suggest-ing
the existence of sperm displacement in D. ananassae. Furthermore, female productivity is increased
after remating in D. ananassae.
