Molecular characterization and evolution of a chemosensory receptor gene family in three notorious rice planthoppers, Nilaparvata lugens, Sogatella furcifera and Laodelphax striatellus, based on genome and transcriptome analyses

Conserved odorant co‐receptor (Orco) genes are closely related to insect olfaction. Knockdown Orco rice planthoppers lose much of their olfactory ability and fail to seek out rice plants. BACKGROUND The white‐backed planthopper (WBPH) Sogatella furcifera, the brown planthopper (BPH) Nilaparvata luge...
