The western flower thrips (Frankliniella occidentalis) is a polyphagous herbivore that causes serious damages on many agricultural plants, and also transmits several plant viruses. However, no pesticide provides complete control of this species, and insecticide resistance has emerged around the world. We previously indicate that the JA-regulated plant defense restricts thrips performance and preference. In this project, we indicated that engineering of plant defense system could perform successful control of thrips behavior. In addition, several plant defense compounds, up regulated by thrips feeding can also affect thrips behavior. We developed the transgenic plants which overproduce some plant defense compounds under non-feeding condition clearly decrease the plant damage by thrips. Our results indicated that plant defense system could be good target for thrips control and thrips damage could be preventable by varying the plant defense conditions.
