Identification of genes involved in insectiside resistance in the brown planthopper, Nilaparvata lugens

The brown planthopper, Nilaparvata lugens (Stal, 1854) is a important pest of rice in Asia. Several strains of N. lugens developed resistance to many insecticides including imidacloprid, leading to serious damages in paddy fields. The goals of this project are to identify genes responsible for the resistances by genome-wide gene analysis and clarify the mechanisms. We also aim to isolate DNA markers which are usable for the development of molecular diagnosis methods which enables simple, rapid and precise monitoring of the development of resistance. This study will facilitate establishing a better management system to prevent or largely delay the development of insecticide resistance in N. lugens.
