The susceptibility of five north Indian populations of Bemisia tabaci (Genn.) against a neonicotinoid insecticide, imidacloprid and a comparatively novel, diamide insecticide cyantraniliprole has been analysed in this study. It was found that the Sriganganagar and Bathinda populations were moderately resistant to imidacloprid with LC50 values 845.55 and 765.65 mg/ l, respectively; while, the LC50 value for cyantraniliprole was around 4.5 and 4.3 mg/ l for both the populations. The relative resistance ratio for imidacloprid was 14.53 and 13.16 for Sriganganagar and Bathinda populations, respectively, whereas, for cyantraniliprole, no resistance was observed. The pairwise comparisons of LC50s of various populations did not exhibit any cross-resistance. The results of the study demonstrate the possibility of using cyantraniliprole as an alternative for imidacloprid resistant B. tabaci populations in north India.
