Field experiments on Bio-efficacy of insecticides against foliar thrips (Scirtothrips dorsalis, Caliothrips indicus and Frankliniella schultzei) in summer groundnut was carried out at Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh during consecutive three year i.e., 2017-18, 2018- 19 and 2019-2020. All the treatments were significantly superior over untreated check. Results of the experiment indicated that the lowest leaf damage percentage was observed in the treatment of spinosad 45 SC 0.0135%, it was statistically at par with difenthiuron 50 WP 0.05% and imidacloprid 17.8 SL 0.0072% after seven and fifteen days of first spray and second spray of the all the season. The treatments of thiamethoxam 25 WG 0.0125%, profenophos 40 + cypermethrin 4 EC 0.044 % and profenophos 50 EC 0.05% as mediocre, whereas buprofezin 25 EC 0.025% and nuvaluron 10 EC 0.01% found the least effective.
