The cross-resistance to etofenprox in Nilaparvata lugens with a high adaptability to resistant rice variety IR56

Abstract

The application of resistant rice varieties and insecticides represents two crucial strategies for managing the brown planthopper (BPH), Nilaparvata lugens (Stål). Insects often employ similar detoxification mechanisms to metabolize plant secondary metabolites and insecticides, which poses a potential risk that BPH population adapted to resistant rice may also obtain resistance to some insecticides.
