Abstract

The high socioeconomic value of corn (Zea mays L.) and the need to increase productivity have driven the growth of cultivable areas, which has generated major challenges in the phytosanitary control of crops. The corn smut complex, transmitted by the corn rootworm (Dalbulus maidis) is responsible for significant losses in productivity and management techniques capable of reducing the severity of the damage caused by the insect are still scarce. Also, in view of the attempt of containment and the use of pesticides in large scale that have generated concern by the numerous risks and adverse effects. With this, this work aimed to evaluate the potential of the essential oil (EO) of noni (Morinda citrifolia) as an alternative control of the corn leafhopper and evaluate its phytotoxic effect. For this, the plants and leafhoppers were submitted to the EO by contact, being the toxicity on the leafhopper observed through the mortality of the insects. The Noni EO demonstrated insecticidal potential, selectivity on non-target organisms and was not toxic to plants.
