The aim of this research was to test the efficacy of different insecticides, and dosage against Pseudoplusia includens in the soybean culture. The treatments were: (1) alphacypermethrin + teflubenzuron, (2) teflubenzuron, (3) diflubenzuron and (4) profenophos + lufenuron, in different doses. All the insecticides tested in this research presented high efficacy on the control of Pseudoplusia includens in the soybean culture. These insecticides and dosages were: (1) mixture of alphacypermethrin and teflubenzuron at dosages from 9.0 to 11.25 g a.i.ha-1, (2) teflubenzuron at dosage from 6 to 12 g a.i.ha-1, (3) diflubenzuron at dosage from 10 to 20 g a.i.ha-1 and (4) the mixture profenophos and lufenuron at dosage 75.0 and 7.5 g a.i.ha-1, respectively. All these insecticides after 15 days of application promote 100% dead caterpillars. None these insecticides decrease soybean yield.
