| Outline of Final Research Achievements |
The American serpentine leafminer (Liriomyza trifolii) is one of the most serious herbivore with huge host range. Due to the existence of insecticide resistance, this leafminer is difficult to control. Therefore, elucidation of the molecular mechanism of plant response and resistance to the leafminers is important for understanding the factors that affect host determining of the leafminers, which may finally contribute the development of new methods to prevent damage. The larvae of leafminers have unique feeding manner, forming tunnels (mining-type feeding). On the other hand, the adults have piercing-type feeding manner. So far, we have studied the importance of JA plant defense system in plant resistance to leafminer feeding and its host plant suitability. In this project, we identified the plant metabolites, which control leafminer behaviors, and analyzed the function of this metabolites from the viewpoint of interaction between plants and herbivore.
