Habitat marking: males attracted to residual odors of two Drosophila species

Abstract

We have found that males of the sibling species D. melanogaster and D. simulans are preferentially attracted to sites marked by the residual odors of conspecific females, especially if non-virgin. In natural populations, this could enhance sexual selection among males, and cause some isolation at the microhabitat level. © 1984 Birkhäuser Verlag Basel.
