provides evidence for sperm precedence of the second male to mate, suggest-
ing the existence of sperm displacement in
D. ananassae (Singh and Singh,
2001).

ACKNOWLEDGMENTS

Financial support from the UGC, New Delhi, in the form of a research
project to B.N.S. and a project fellowship to S.R.S. is gratefully acknowledged.
