Population fluctuation of thrips studies on chilli during kharif 2022-23 and 2023-24, at Student’s Instructional Farm (SIF) of the Department of Agronomy, C. S. Azad University of Agriculture and Technology, Kanpur Uttar Pradesh. The experimental result revealed that treatment Imidacloprid 17.8 SL @ 0.2 ml/l with 84.69 percent reduction over control (PROC) proved best among all treatments in 3^rd days after 1^st and 2nd spray and also with minimum population at 7^th and 10^th days after spray. The second best treatment was Acetamiprid 20 SP @ 3 g/l) and followed by Spinosad 45 SC 0.2 ml/l, Thiamethoxam 25 WG @ 0.1 ml/l. After these treatments Neem Oil 1500 ppm, Beauveria bassiana 2x10⁹ spore/ml @ 5 ml/l and Metarhizium anisopliae 2x10⁹ spore/ml @ 5 ml/l were effective in relation to reduce the population of thrips. In this experiment we observed that the Imidacloprid proved best to manage the thrips population on chilli crop.
