Because of the damages caused by Dalbulus maidis (Delong & Wolcott, 1923) on crop corn, had been evaluated the effect of insecticides applied on the desiccation management (MD), seed treatment (TS) and foliage spray (PF) to the 10 days after the emergency (DAE), on D. maidis. The assays had been developed in Fundação Chapadão in Chapadão of Sul (MS) city, from 29/10/04 to 27/02/05, with experimental design of randomized blocks, with ten treatments and four replicates. The used treatments had been: monocrotophós and cypermethrin (MD), thiodicarb + imidacloprid, thiametoxan, clothianidim, imidacloprid and acetamiprid (TS), cypermethrin + thiametoxan and endossulfan + NaCl (PF), in the recommended dosages, and one control without insecticide. It was carried counting of the number of D. maidis, calculating the insecticides efficiency to 14, 20, 28 and 40 DAE. For D. maidis, the use of the insecticides in TS and PF had been efficient in the 14 DAE, being imidacloprid (TS) and cypermethrin + thiametoxan (PF) had presented, respectively, 72 and 61% of efficiency to the 40 DAE, demonstrating residual effect.
