| Outline of Final Research Achievements |
Through the survey with citizens, it turned to be clear that the distribution range of an alien grasshopper, Atractomorpha sinensis has been expanding from Kobe and Osaka area to adjacent regions.
By comparing DNA sequences of specimens introduced to Osaka with those of China, Taiwan and South west islands of Japan（native）and Hawaii (introduced), one of the origin of the introduced population in Osaka is presumed to be originated in China. No hybrid of this species and native congener, A. lata, however, a reproductive interference may occur throgh the gurding behaviour of males on the female.
