Study of pest control using weak vibrations, and forest management
- Project Description
Since insects have the habit of avoiding vibrations traveling through solid media, vibrations can be used to control the behavior of insects. This study clarifies the characteristics of vibrations that control the behavior and senses of forest insect pests (mainly the beetle Monochamus alternatus), and aims to develop methods to use weak vibrations artificially generated in trees to prevent insect damage to forests. This technique may be used instead of chemical pesticides and will enable forest management that will have a minimal effect on the forest ecosystem.
