Introduction of Research Achievement “Pest control by blue semiconductor laser – Pest shooting technology using laser light without pesticides –”

A future where we can target pests with laser light and exterminate pests without using pesticides seems likely to be realized with Japanese technology. Researchers at Osaka University’s Institute of Laser Engineering have discovered that the chest and face are vital spots of the leaf-eating pest Spodoptera litula. After detecting and tracking flying pests as images, it is now possible to shoot them down by irradiating them with laser light. This technology will lead to improved agricultural production efficiency, and the research institute is proceeding with development with the aim of putting it into practical use by 2025 at the earliest.
