| Enemy odors help flies protect their offspring Posted: 16 Dec 2015 12:16 PM PST In nature, up to 80 percent of Drosophila melanogaster larvae are parasitized by Leptopilina wasps.

Researchers have now identified that chemical odorant compounds produced by the wasps (including their sex pheromone) trigger avoidance behavior in these flies. |
