Abstract:Resistance monitoring plays an important role in directing the scientific application of insecticides and evaluating the effect of resistancemanagement in paddy fields. The ricestem dipping and topical methods are popularly used for resistance monitoring in the brown and whitebacked brown planthopper. However, the riceseedling dipping method has been developed as a more suitable method for the small brown planthopper. These three resistance monitoring methods are discussed in order to provide a standard technique for monitoring the pesticide resistance of rice planthoppers.
