Microscopic mites (0.1-0.3 mm), body shape is worm-like or spindle-shaped.
All postembryonic stages have only 4 legs (the back two pairs are reduced).
Includes herbivorous representatives, including dangerous pests of forest and cultivated plants (pear mite, apple gall mite, plum shoot mite, grape mite and other mites).
Includes the smallest representative of the entire arachnid class in the world: the species Abacarus hystrix (one of the smallest species of the arthropod type in general), their length is from 0.125 to 0.250 mm.

Mites parasitize inside vegetative and generative organs, causing the formation of galls and weakening plants.
The nature of the damage is varied.
This may include a change in color and deformation of leaf blades, the formation of galls of various shapes, abnormal growth or branching of shoots, deformation of young shoots, fruits and flowers.
Some species of this family carry pathogens of viral diseases.

The key to success is compliance with agricultural technology:
1 Removal of weeds and fallen leaves, since some species overwinter on fallen leaves. 2 Mandatory burning of vines remaining after autumn pruning.
Modern chemical preparations allow you to effectively combat spider mites and gall mites on grapes.
Among the preparations are: Thiovit Jet, Actofit, BI-58
