Biological Pest Control in Maize Crop in Brazil: A Review

The areas of maize production harbor a high number of insect species, some of which are considered pests that cause damage to the crop. The methods of pest control have been a cause of concern for the society since the use of chemicals and the environmental problems arising from this practice indicate the need to search for alternatives to control. In this sense, it is necessary to seek an agricultural production system that contemplates environmental sustainability and promotes biodiversity in the Agrosystem, among which the use of biological agents is highlighted. The objective of this research was to update through a bibliographic review the advances in the literature on biological control of maize crop pests. For the development of this article, we used the method of approach the analytical and as procedural method the monographic, through bibliographic research, using specialized doctrines, appropriate to the object of the study and legislations. Because of the observed aspects, it is possible to conclude that the group of natural enemies that act as biological control agents is formed by parasitoids, predators and entomopathogenic microorganisms. The rationalization of the use of chemicals should be associated with the use of biodefensives in integrated pest management. Advances in the legislation of biological products in Brazil are fundamental to give speed to the registration of new alternatives of biological control, aimed at the safety of the environment, human health and that are generated without the exploratory use of biodiversity.
