| Outline of Final Research Achievements |
Species-specific mating preference plays important role for the generation and maintenance of biodiversity. However, what kind of change in neural circuits causes the evolution of the preference is largely unknown. To solve this question, I searched the difference of neural circuit causing the species difference of pheromone and song preference in Drosophila. As a result, I found several differences in the neural circuits, which might be involved in the species difference of these preferences. These findings may provide clues to understand how the mating preference to conspecific individuals has been acquired during evolutionary process.
