Investigations on “Bio-efficacy of newer insecticides and bio pesticides against thrips, Scirtothrips dorsalis Hood on Pomegranate” were conducted at pomegranate Research Block H-25 of ICAR-NRCP, Solapur on cv. ‘Bhagawa’ during Hasta Bahar seasons in 2016-17 and 2017-18. Statistically data was designed in RBD with eight treatment and three replications. Observations were recorded at three, seven and ten days after spraying. On the basis of number of thrips found per plant after all the five sprays the treatment of Chlorantriniliprole 8.8 % + Thiomethoxam 17.5 % SC (82.62%) was found to be the most effective in three, seven and ten days after spraying recorded 14.12, 14.60 and 18.70 thrips per plant respectively. The minimum effectiveness was noticed in Karanj oil + Neem oil mixture recoded 22.41, 21.98 and 26.87thrips per plant after three, seven and ten days after spraying respectively. The order of effectiveness of these treatments in descending order was Chlorantriniliprole 8.8 % + Thiomethoxam 17.5 % SC> Thiomethoxam 12.5% + Lambda-cyhalothrin 9.5% ZC > Lambda-cyhalothrin 4.6% + Chlorantriniliprole 9.3% ZC > Buprofezin 15% + Acephate 35% WP > Azadirachtin 300 PPM > Karanj oil > Karanj oil + Neem oil > Control. The chemical treatments were more effective than bio pesticides which was treated in this experiment.
