Brazil is one of the most extensive users of Biological Control (BC) (including both micro and macroorganisms) in the struggle to control agricultural pests. Nowadays, BC is seen not only as a measure supported by bioagents but also as an approach involving biofertilizers and biostimulants. This is part of a broader view that encompasses bioinputs, defined as agro-industrial products or processes developed from enzymes, extracts (from plants or microorganisms), microorganisms, macroorganisms (invertebrates), secondary metabolites, and semiochemicals (e.g., pheromones), all designated for BC. Sustainability is the worldwide need of the moment. Achieving this goal is a genuine concern of sustainable agriculture projects which is made possible by, among other measures, using biological products to control pests. As a leader in tropical agriculture, Brazil must increasingly use BC to meet the requirements of the international markets for agricultural products free from chemical residues. Entomological pest control involves both micro (fungi, bacteria, virus, nematodes, etc.) and macroorganisms (insects and mites). Although categorized as semiochemicals, pheromones are commonly included in BC, in this case, to monitor or control pests (e.g., the male confusion technique). In the current philosophy of Integrated Pest Management (IPM), aiming toward sustainability, BC should not be considered in isolation but as a component of IPM, i.e., as a method, similar to other control methods, to maintain pest populations below the economic injury level, which considers economic, ecological, and social criteria.(AU)
