Abstract

<p>It is an undeniable fact that herbivore attack is a major problem in agriculture.　As a result, a number of insecticides have been developed to support agricultural production.　In recent years, however, the emergence of the herbivores that developed highly insecticide resistance has become a global problem.　In particular, thrips have developed a high level of insecticide resistance in various parts of the world, and they have been rampant both in Japan and overseas.　In some areas, this is a serious situation leading to abandonment of cultivation.　Thysanoptera have a wide host range, causing damage to many crops and vegetables as well as flowers.　In addition, since these pest species are also vectors of plant viruses, they cause viral diseases such as tomato spotted wilt virus, chrysanthemum stem necrosis virus on crops, causing multiple damages. Moreover, since thrips are only about 1〜2 millimeters long, it is not easy to prevent them from invading large gardening facilities, such as plant factories, and once they do, the damage is devastating.　Because thrips can increase their population with females alone for parthenogenesis without males, invasion by only one female is a significant risk.　Thus, the development of new control measures against thrips has long been required, but a fundamental solution has yet to be reached.　Therefore, we have developed a repellent for the purpose of controlling thrips’ behavior based on the interaction between thrips and plants, rather than killing them, and are advancing research and development with the aim of developing innovative behavior control technology.</p>
