A field trial was carried out in Pichit to evaluate the efficacy of some insecticides on the suppression of thrips attacking pummelo. The specimens collected throughout the period of the experiment indicated that each species of thrips tended to select a specific feeding site on Tha Koi cultivar as Thrips sp. was found mainly on flowers whereas Scirtothrip dorsalis preferred to attack young leaves and juvenile shoots. The results demonstrated that monocrotophos, carbosulfan and permethrin were effective against S. dorsalis damaging young leaves and juvenile shoots. For controlling those attacking mainly flowers and reducing the scarred damage on fruits, four chemicals were recommended e.g. permethrin, cyhalothrin, carbosulfan and monocrotophos.
