| Outline of Final Research Achievements |
Recently, the market for both exotic and interior insects especially rhinoceros and stag beetles as pets is growing fast in Japan. Large-scale trading of pet insects in Japan may cause significant problems, such as genetic disturbance (hybridization) to some native taxa and decreasing in their populations, as they may become invasive.
Under these situations, we tried to estimate ESU (Evolutionarily Significant Unit) based on the molecular analysis for Japanese native taxa, and found that most insular populations should be considered as ESU. Further, we applied both molecular and morphological analyses to the ecological risk assessment and management of pet insects including interior alien species by identifying the place of their detailed origin, and by identifying their larvae and female adults which are not easily distinguished from one another.
