About Mites: the wider group

Order-level background for Trombidiformes, the group containing Tetranychus urticae. Species-specific details appear above.

Group overview

Trombidiformes includes ~26,000 described species of mites including velvet mites, chiggers, and spider mites. Spider mites (Tetranychidae) are among the most destructive agricultural pests worldwide.

Ecological role of the group

Velvet mites are important soil predators. Chigger larvae are parasitic on vertebrates and can cause intense itching (trombidiosis). Some mite species are used as biological control agents against pest mites in agriculture.

Economic and practical significance of the group

Spider mites cause billions of dollars in crop damage globally, affecting over 1,100 plant species. The two-spotted spider mite (Tetranychus urticae) has developed resistance to more pesticides than any other arthropod.

Recorded sources for this group: USDA, agricultural pest management research. Imported estimates may describe particular regions or reporting periods.
