| Outline of Final Research Achievements |
In order to elucidate caste-specific gene expression, RNAseq-based comparative transcriptome was performed in Ponerine ant Diacamma sp. and a Yellow jacket, Vespula shidai. In Diacamma, patterns of social interaction and its consequence on behavioral variation was clarified by auto-tracking system. The draft genome of Diacamma sp. is being annotated and trascriptomic data is being analyzed.

| Academic Significance and Societal Importance of the Research Achievements |
社会性昆虫では，個体間の対立が行動，発生，遺伝子発現などさまざまなレベルで見られる．本研究では，個体間相互作用のパターンを画像による自動認識（トラッキング）を用いて，詳細にデータ化することに成功した．また，ゲノムレベルでの対立構造を解明する上での基本情報となるカースト特異的遺伝子について，トゲオオハリアリおよびシダクロスズメバチにおいて解析をすすめ，カースト分化を左右しうる候補遺伝子を得た．これらの成果は，社会行動や集団での行動パターン・意思決定が生み出される進化的・遺伝的メカニズムの解明の端緒となると考えられ，利他行動・利己的行動を引き起こす遺伝子の広範な種間比較において重要な成果である．
