| Outline of Final Research Achievements |
Platypus quercivorus is the vector beetle of the pathogenic fungi which cause Japanese oak wilt. The method to measure the direction of beetle flight immediately after their emergence was developed. Experiments with flight mill revealed that the flight capacity of the beetle is over 20km, and that the flight distance of males and females get longer in the presence of aggregation pheromone. It was also shown that the positive phototaxis of the beetle decrease after flight, suggesting that this taxis is not necessary for the beetle after certain flight. Laboratory studies using olfactometer revealed that the beetle is attracted to the volatile from fresh leaves and repel the volatile from dried leaves of their host tree, and that patterns of these responses change during their flight in a different way between males and females. It became clear that this beetle has a strong nature of a primary pest.
