Guruprasad GS All the selected populations differed in their susceptibility to sulfoxaflor. In general, Gangavati and Scientist, ARS, Gangavati, Sindhanur BPH population recorded higher LC50 values of 29.95 and 27.75 ppm respectively, followed UAS, Raichur, Karnataka, India by Ballari (26.16 ppm), Manvi (25.03 ppm) and Devadurga (22.68 ppm). Lowest LC50 value was observed in population collected from Kembhavi (21.56 ppm) during 2014-15. The similar trend was Vijaykumar Ghante noticed during 2015-16 season. The comparison studies were made with dinotefuran 20 SG and Scientist, MARS, UAS, buprofezin 25 SC insecticides for a population collected from Gangavati. Raichur, Karnataka, India Keywords: Nilaparvata lugens, Insecticide resistance, baseline susceptibility and sulfoxaflor Introduction The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is continuing to be a serious pest of rice in Asia. In 1927 it was first time reported as sporadic pest on rice crop of Guntur district in Andhra Pradesh, India [1].
