This review contains the characteristics of groups and species of mites used or recommended in the control of plant pest and of weeds. For the control of stored product pests pyemotids, cheyletids and Hypoaspis are discussed. Phytoseiids and Hemisarcoptes malus are described as agents of biological control of pest of orchards, parks and greenhouses. Eriophyoid mites as the most promising group for the control of weeds are also characterized.
Frankliniella occidentalis is the most important pest in greenhouse crops. Successful control of this pest is very difficult. In laboratory and greenhouses studies predator mites Amblyseius swirskii and Amblyseius cucumeris showed a high efficacy used together in control of western flower thrips (83% mortality). Predators used separately were less efficacious against the pest (about 63% mortality). The studies showed neutral interaction of A. swirskii and A. cucumeris populations in control of western flower thrips.
