Mites are microscopic arthropods belonging to the class Arachnida and the order Acari. There are many phytophagous species that feed on the cellular content of plants, such as Tetranychus urticae (red spider), Polyphagotarsonemus latus (bud mite) or Brevipalpus spp. Their small size, rapid reproduction and ability to adapt make them one of the most persistent pests in various crops. Adults usually have four pairs of legs and an oval body, and reproduce by laying eggs on the underside of leaves or in protected areas of the foliage. Under favorable conditions, such as high temperatures and low humidity, development from egg to adult can be completed in less than a week. Females can lay dozens of eggs in a few days, leading to explosive populations. Immature forms go through larval and nymphal stages before reaching maturity. Many species survive in a dormant state during the winter in plant remains or crop structures, reinfesting the plants in spring.
