The data recorded during the surveys revealed that the maximum population of thrips were recorded at Degaon (17.2/10 cm twig) during first survey and during second survey at Laxmitakali (19.1/ 10 cm twig) Lowest population noticed at Laxmitakali (4.5/10 cm twig) and Bondale (4.0/10 cm twig) during first and second survey respectively. The maximum population of Aphids were recorded from Tisangi (17.1 aphids/10 cm twig) during first survey and during second survey at Bhalvani (14.6 aphids /10 cm twig). The lowest population of aphid seen at Maololi (5.1/10 cm twig) during first survey and during the second survey at Laxmitakali (4.5/10 cm twig).Studies on bio-efficacy of newer insecticides against aphids revealed that the treatment with thiamethoxam 12.60 + lambda cyhalothrin 9.50 ZC was found most superior in reducing the population of aphids followed by flonicamide 50 WG and Cyantraniliprole 10.26 OD. In case of thrips, treatment with Cyantraniliprole10 OD followed by Spinosad 45SC and flonicamide 50 WG were the most effective. The per cent fruit infestation (on number and weight basis) revealed that the treatment of spinosad 45 SC was found effective in reducing the fruit damage.
