| Outline of Final Research Achievements |
An entomophilic nematode Caenorhabditis japonica has a species-specific relationship with its carrier bug Parastrachia japonensis. We hypothesized that this relationship is based on a chemical communication via semiochemical and conducted several experiments to clarify the mechanism in detail.
Results obtained in preference tests showed that C. japonica uses semiochemical(s) contained in hexane extract of the host insect for host recognition, of which list has been narrowed by GC-MS analysis. Also, C. japonica was strongly attracted to benzaldehyde, which is known as one of the attractants for C. elegans. This suggests that C. japonica may equip and utilize a neural network similar to that of C. elegans.
