Resumo

This work aimed to evaluate the insecticidal potential of Cymbopogon citratus essential oil at the concentrations of 0.1; 0.5; 1.0; 1.5; and 2.0% v/v as an alternative to conventional products on adult individuals of D. maidis, as well as the use of two controls: one positive, composed of the chemical insecticide Perito 070 SG (acephate) at 1 kg∙ha-1, and two negative controls, Tween 80® 0.5% v/v and distilled water. The bioassays were performed in triplicate, with three replicates of ten individuals per replicate, totaling 30 individuals per treatment. Maize plants were grown in bottles with a capacity of 2 L and 10 adult individuals were transferred. The treatments were sprayed, and the plants were covered with voile fabric. It was observed that at the concentrations of 0.1%; 0.5% and 1.0% there was no significant difference relative to the negative control, whereas at the concentrations of 1.5% and 2.0% v/v there was a significant difference from the negative controls, with mortality similar to the positive control, being a potential biopesticide in the control of D. maidis and a potential candidate as a bioherbicide in the control of volunteer corn plants because it caused toxicity on corn plants from concentrations of 1.0% v/v.
