| Outline of Final Research Achievements |
In this study, we focused on the fighting behavior exhibited by insects, including crickets, in order to clarify how autonomous individual behavior of crickets creates order in the behavior of the entire group through local interactions among individuals. In cricket fights, when a winner is determined, the winning individual maintains its aggressiveness, while the loser attenuates its aggressiveness (called the losing effect). We constructed a system that intervenes in the fighting behavior of crickets using a small robot. By using the developed system we were able to change the behavior of crickets with the losing effect.
We also examined the mechanism of recovery from the losing effect, and found that visual stimuli, in addition to contact with other individuals, play an important role in the recovery from the losing effect.

本研究では，コオロギが個体間の局所的な相互作用を通じて，自律的な個体の行動がどのように集団全体の振る舞いに秩序を創発するかを明らかにするため，小型移動ロボットにて闘争行動に介入できるシステムを構築した．そして，そのシステムにて対象個体の闘争性を変化させることができることを確認した．従って，構築したシステムにより，対象個体の闘争性を変化させ，個体間の秩序形成の促進および阻害が可能となり，より深い秩序形成メカニズムの理解に繋がっていく．また，このような外部からの介入手法が有効であることは，今後，コオロギ同士の闘争行動解明を含む様々な生物の行動解析において，有用な知見となりえると考えられる.
