Abstract

<p>Herbivore attack is one of the most important factors to decrease the agricultural production.　Many types of insecticide were developed and utilized to control the insect pests in the world.　Insecticides have been supporting the world agriculture.　However recently, it has become a big problem that many herbivores with insecticide resistance were appeared.　Especially, thrips developed highly resistance to many types of insecticide, and can cause serious problems in many crops, vegetables, fruits and flower plants.　This tiny and polyphagous pest insect is an also vector of tospoviruses, Therefore, both the feeding damage and the tospovirus disease caused by thrips are serious problems.　We have demonstrated that jasmonate （JA） dependent plant induced defense system restricts both thrips performance and preference.　JA treatment to the plants increases the thrips avoidance and controls the thrips behavior.　We also introduce our approach to use the JA analog, prohydrojasmon for thrips control.</p>
