The present study aimed at screening fifteen genotypes of cotton (Gossypium hirsutum L.) for population dynamics of thrips, Thrips tabaci Lindemann. This study was carried out at the Cotton Research Station, Faisalabad, Pakistan during the two cropping seasons 2016 and 2017. The experiment was conducted under Randomized Complete Block Design (RCBD) with three replications. The results showed that FH-142 proved to be least attractive cultivar with 0.67 T. tabaci/leaf in September and October-2016 while in 2017 T. tabaci population observed was 1.33/leaf in May, 1.67/leaf in September and 2.67 /leaf in October. The maximum population of T. tabaci was recorded on FH-451 (15.50/leaf) followed by FH-455 (14.67/leaf during 2017. On cumulative basis, highest peak of T. tabaci population was observed on FH-455 (12.92/leaf). In conclusion, advanced genotypes of transgenic cotton was proved to resist the population buildup of T. tabaci throughout the period of study.
