An experiment was conducted to observe the bio-efficacy of neonicotinoids against Amrasca biguttula biguttula (Ishida), Aphis gossypii Glover of okra (Abelmoschus esculentus L. Moench)" during kharif season of 2014 at the Entomological experimental field, college of agriculture JNKVV Jabalpur (M.P.). Overall lowest mean of jassid recorded in the plot treated with thiamethoxam 25% WG @ 50 g a.i./ha ( 21.88 jassid / 30 leaves) followed by thiamethoxam 25% WG @ 25 g a.i./ha (36.41 jassid / 30 leaves). However, treatment thiamethoxam 25% WG @ 50 g a.i./ha and thiamethoxam 25% WG @ 25 g a.i./the ha were observed significantly less (6.50 aphid / 30 leaves) and (13.80 aphid / 30 leaves) aphid population respectively as compared the rest of treatment. On the basis of the above result thiamethoxam 25% WG @ 50 g a.i./ha and thiamethoxam 25% WG @ 25 g a.i./ha were most effective treatment against jassid and aphid, imidacloprid 17.8% SL @ 21.36 g a.i./ha and emamectin benzoate 5% SG @ 12 g a.i./ ha were found moderately effective than other treatments in respect of less damaged okra.
