| Outline of Final Research Achievements |
This study aims to examine that individual recognition is performed among colony mates in pre-emergence colonies of a polygynous wasp, Ropalidia fasciata. First, area of each 3 part in individuals' head was not significantly different between dominant and subordinate individuals. Next, dominant and subordinate individuals were individually introduced into alien colonies in field. However, aggressive responses of individuals from recipient colonies were not significantly different between dominant and subordinate individuals. These results suggest that individual recognition is not performed by non-nestmate individuals in pre-emergence colonies of R. fasciata.

| Academic Significance and Societal Importance of the Research Achievements |
社会性カリバチのコロニー内の優位個体と劣位個体の識別については、従来の研究ではアシナガバチ属（Polistes）においてのみ、行われてきた。本研究は、チビアシナガバチ属（Ropalidia）の一種を材料にして初めて実施した。また、コロニー内の個体識別に関する研究は、視覚による情報、もしくは嗅覚による情報のいずれかが、扱われることが多かった。本研究は、どちらによる情報からも、優位個体と劣位個体が識別される可能性があったかを検討した画期的な成果と言える。
