The effect of insecticides for the control of Dichelops melacanthus on maize were evaluated in regard to desiccation management (MD), seed treatment (TS) and foliage spray (PF) up to 10 days after plant emergence (DAE). The trials were carried out on the Zeca Silva farm in Chapadão do Sul, state of Minas Gerais, Brazil, from 10/29/2004 to 3/ 6/2005, using a randomized block design, with 10 treatments and 4 replicates. The treatments were: monocrotophos 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. The percentage of plants attacked by D. melacanthus was evaluated up to the 25th DAE. The use of insecticides in MD and PF did not provide reduction of attacked plants by D. melacanthus, while imidacloprid (TS) was more efficient, resulting in the least percentage (4%) of plants attacked.
