Evaluation of different management tactics against chilli thrips Scirtothrips dorsalis was carried at Agricultural Research Institute, Tarnab during 2016. Experiment was carried out in Randomized Complete Block Design (RCBD) with three replications. Six control measures i.e Solvigo 108SC, Confidor 200SC, Chrysoperla carneaParthenium hysterophorus 7%, Combination-1 (P. hysterophorus 7% extract + C. carnea) and Combinaion-2 (P. hysterophorus 7% extract + Pest Oil@500 ml ha-1) including control were applied twice at 30 days interval. Results revealed that all the tested control measures were found to be superior than control however in both the spray application Solvigo was found to be the most effective in reducing nymphal and adult thrips infestation with (1.79, 2.83) nymphal and (0.49, 0.85) adult population, followed by Confidor after first and Second spray respectively. C. carnea alone did not give significant control of thrips as compared to the plot where C. carnea were applied in combination with botanicals. Highest yield was obtained from the plots treated with Solvigo while the lowest yield was recorded from Control (untreated plots). It was concluded that Solvigo and Confidor were found to be better in managing chilli thrips infestation and can be incorporated in IPM programs against chilli thrips.
