Suppression of male courtship by a Drosophila pheromone receptor

Tetsuya Miyamoto & Hubert Amrein

In male Drosophila, chemosensory cues control many aspects of social behavior. We found that males with a mutated Gustatory receptor 32a gene (Gr32a) show high courtship toward males and mated females, indicating that GR32a functions as a pheromone receptor for a male inhibitory pheromone.
