The experiment was conducted during Kh-2014 and Kh-2015 to study the relative susceptibility of different BPH populations against different insecticides viz. Imidacloprid , Dinotefuron 20SG, Acetamiprid 20SP, Acephate 75SP and Buprofezin 25SC. Among all the treatments, mortality of BPH glasshouse population 3 and 7 DAE of insecticides were found to be maximum in Dinotefuron 20SG during both the years, whereas mortality of different field populations of target locations varied greatly. Among all the populations checked for their susceptibility, Dhamatari population was found to be least susceptible to recommended doses of insecticides. | Relative susceptibility of different BPH Nilaparvata lugens Stal. populations of Chhattisgarh against different insecticides
