| Outline of Final Research Achievements |
The purpose of this research is to reveal why the Epicephala moth feed on only one host species through its larval stage. I conducted two experiments, the laboratory experiments using cultivated plants and moth larvae and electrophysiological tests. It revealed that the survival rates of Epicephala larvae feeding on the seeds of non-host species decreased, and the female adults of Epicephala can detect their host species using some specific compounds emitted from host flowers. Although the cause of the Epicephala moths could not develop on non-host species under my laboratory experiments is not unknown, it may be thought that Epicephala larvae can digest only the seeds of host species or their growth rates cannot synchronize with the developing speeds of non-host seeds.
