Biological control of pests is one of the key components of integrated pest management (IPM) systems, contributing to environmental sustainability and biosafety. Among the major advantages of biological control are the presence of indigenous natural enemies and the ability to suppress pest populations that have developed resistance to chemical pesticides. Biological control is considered a low-cost and environmentally friendly management approach with minimal risks to the ecosystem. Predatory mites play a crucial role in biological control programs. They are mainly used in vegetable and ornamental cropping systems, particularly in greenhouses, for the suppression of phytophagous mites, thrips, and whiteflies. Families such as Phytoseiidae, Laelapidae, and Tydeidae are among the most important groups utilized in biological control. Within these, species of Phytoseiidae—with approximately 20 commercially available species worldwide—represent the most significant group of natural enemies of pest mites. Predatory mites such as Amblyseius swirskii, Phytoseiulus persimilis, Neoseiulus cucumeris, and Neoseiulus californicus are among the most effective and widely used biocontrol agents, collectively accounting for nearly two-thirds of the global arthropod biocontrol market. These biological agents have been described as highly effective in controlling various pests and in reducing pesticide use in the production of ornamental, horticultural, and agricultural crops.
