Field experiments were conducted under a shade net house at Hi-Tech Horticulture Farm, Rajasthan Agricultural Research Institute, Durgapura, Jaipur (SKN Agriculture University, Jobner, Jaipur, Rajasthan) to investigate the effectiveness of eleven bio-rationale and newer insecticide molecules against thrips, Scirtothrips dorsalis Hood during summer 2014 and 2015 on capsicum (Capsicum annum L). The results revealed that during 2014 and 2015 all the treatments proved significantly superior in reducing the upward leaf curling in comparison to the control at 7, 11 and 13 weeks after transplanting (WAT). The minimum leaf curling (5.84%) was recorded in the treatment of fipronil 5 SC @ 0.005%, which was significantly superior followed by imidacloprid 17.8 SL @ 0.0058 % (7.50 %) and acephate 75 SP @ 0.075 % at 7 WAT. At 11 WAT, minimum leaf curling (3.33%) was recorded in the treatment of fipronil 5 SC @ 0.005%, which was significantly superior. The minimum leaf curling (4.17%) was recorded in the treatment of fipronil 5 SC @ 0.005% and imidacloprid 17.8 SL @ 0.0058%, which was significantly superior followed by acephate 75 SP @ 0.075% (5.84%) at 13 WAT. The overall effect indicated that the minimum leaf curling (4.44%) was recorded in the treatment of fipronil 5 SC @ 0.005% followed by imidacloprid 17.8 SL @ 0.0058 (5.83%) and acephate 75 SP @ 0.075% (7.23%). The study revealed that fipronil 5 SC @ 1 ml/l or imidacloprid @ 17.8 SL 0.33 ml/l or acephate 75 SP @ 1 g/l could be suggested to the farmers for the management of thrips on capsicum under shade net house conditions during summer for off-season production.
