Abstract: A field experiment was conducted at Anand Agricultural University, Anand during 2018 to assess the bio-efficacy of various insecticides against hopper Amritodus atkinsoni Lethierry infesting mango. Of the eight evaluated insecticides thiamethoxam 12.6% + lambda-cyhalothrin 9.5% ZC, thiamethoxam 25 WG and acephate 50% + imidacloprid 1.8% SP were found the most effective in reducing the incidence of A. atkinsoni. However, buprofezin 15% + acephate 35% WP, acetamiprid 20 SP and buprofezin 25 SC were found mediocre in their effectiveness. Maximum (145.44 q/ha) mango fruit yield was recorded from the trees treated with thiamethoxam + lambda-cyhalothrin which was at par with thiamethoxam (142.24 q/ha) and acephate + imidacloprid (137.45 q/ha). The highest (1: 14.84) NICBR was obtained with the treatment of thiamethoxam + lambda-cyhalothrin followed by thiamethoxam (1: 14.23), acephate + imidacloprid (1: 13.32) and buprofezin + acephate (1: 10.30).
