ABSTRACT
There are hundreds of species of ornamental plants used in landscape projects and, recently, the presence of the aphid Takecallis taiwanus was identified infesting bamboo in hedges. This work was carried out to evaluate the efficiency of chlorpyrifos, malathion and fenitrothion for the control. The treatments were: chlorpyrifos at 10 mL/10 L water, malathion at 30 mL/10 L water and fenitrothion at 200 mL/10 L water. All tested formulations were efficient for the control of aphid T. taiwanus on B. gracilis until 21 days after application.
