The research groups of Telecommunications University, Forest Research and Management Organization Forest Research Institute, Tohoku Special Steel, Miyagi Prefectural Agricultural and Horticultural Research Institute, Ryukyu University, Kanagawa Prefectural Agricultural Technology Center, and Hyogo Prefectural Agriculture, Forestry and Fisheries Technology Center are pests. We have developed a new technology to exterminate pests by vibration and obtained a patent.The vibration generator is scheduled to be commercialized by 2023.
According to the Forest Research and Maintenance Organization, whiteflies such as whitefly and greenhouse whitefly are pests of vegetables such as tomatoes, which produce excrement that causes soot disease in which photosynthesis is inhibited, and plants that cause fatal damage to tomatoes. It carries the viral disease tomato yellowfly.It used to be exterminated with pesticides, but it has become more resistant to various pesticides.
Therefore, the research group focused on the fact that many insects are sensitive to vibration, and in the summer of 2018, at a tomato cultivation facility in Miyagi prefecture, using a vibration generator using a material that expands and contracts due to local changes, an experiment to exterminate greenhouse whiteflies was conducted. did.As a result, it was found that the number of parasitizing greenhouse whitefly larvae was smaller than that of tomatoes that were not given to the leaves of tomatoes that were vibrated.
Vibration-based extermination experiments on greenhouse whiteflies and Bemisia tabaci were also conducted in Kanagawa, Hyogo, and Okinawa prefectures, all of which were confirmed to be effective and led to the acquisition of patents.Tohoku Steel is promoting the commercialization of vibration generators.
