Fig 13. A–P. Dispersal of D. simulans males confronted with odorants of conspecifics and D. melanogaster.

Males tested were non-virgin (A–D and I–L) and virgin (E–H and M–P). White columns indicate percentages of flies that remained in the flask. Black columns stand for percentages of flies found in the Y-tubes connected to vials with conspecific (or D. simulans) odors. Hatched columns show percentages of flies in the Y-tubes connected to empty vials. For further details see Fig 11.
