The objective of the experiment was the evaluation of effectiveness of the insecticides on the control of <em>D.</em><em> melacanthus</em> in corn by adding of sulfur or not, in different control times. In order to evaluate the effect of the insecticide by adding or not sulfur on the control of <em>D.</em> <em>melacanthus</em>, 17 treatments with 4 different insecticides (with and without sulfur, in two different control times plus control) were used to get the results. The experimental design used was the randomized blocks, with four repetitions. The evaluation of effectiveness on stink bugs control was gotten by visual evaluation of the symptoms at 6, 13 and 20 days after emergence (DAE). Analysis of variance by F test (Anova) was done and the averages compared through Scott-knott test (p≤0,05). The pulverization of insecticides was more effective when it was done 4 (DAE), reducing the symptoms and injuries occasioned by the stink bug <em>D.</em> <em>melacanthus</em> and the mortality of damaged plants. The insecticide bifentrina+carbosulfano showed the higher effectiveness on stink bug control. To conclude, the use of sulfur associated to insecticides did not present a significant effect.</p> ER -
