Species‐specific insecticide resistance to imidacloprid and fipronil in the rice planthoppers <i>Nilaparvata lugens</i> and <i>Sogatella furcifera</i> in East and South‐east Asia

Abstract

Species-specific changes in insecticide susceptibility were found in Asian rice planthoppers (i.e. BPH for imidacloprid and WBPH for fipronil). Insecticide resistance in BPH against imidacloprid occurred in East Asia and Indochina, but not in the Philippines. In contrast, insecticide resistance in WBPH against fipronil occurred widely in East and South-east Asia.
