Cigarrinha (Dalbulus maidis) na cultura do milho

Abstract

The objective of this work was to review the literature on the corn leafhopper, its damage to corn plants and the main control methods used for this pest. Corn is a crop of great importance for world agribusiness, and its grains are used in the production of various products. During its development cycle, the crop is subject to attack by various pests and diseases. In recent years, mainly due to the break in the seasonality of corn cultivation, the corn leafhopper has become a pest that causes great concern to producers. It is a sucking insect and with its feeding it causes direct damage to corn plants, however, it is the indirect damage, with the transmission of pathogens, that this pest has greater relevance. The leafhopper transmits the pathogens that cause diseases such as red and pale stunt, as well as the stripe virus, which drastically affect the productivity of the crop. Based on the works reviewed, it was verified that the control of the corn leafhopper must be carried out through the integrated management of pests, concomitantly using different control methods, mainly the chemical method (seed treatment and spraying), genetic and biological, in order to obtain a good control of this pest and minimize the damage caused to the producer.
