Identification and Appearance

Western predatory mite - Typhlodromus occidentalis

Pear shaped. First they are white. Later they take the color of their prey, usually red or brown. Used as primary biocontrol agent of pest mites on many crops. Its benefit to commercial apple, plum, peach, and cherry orchard farming is especially well known.

About Mesostigs: the wider group

Order-level background for Mesostigmata, the group containing Typhlodromus occidentalis. Species-specific details appear above.

Group overview

Mesostigmata includes ~11,500 described species of predatory and parasitic mites. Many species are voracious predators of other mites, springtails, and small insects in soil and leaf litter.

Ecological role of the group

Mesostigmatid mites are key regulators of soil arthropod communities. Some species are phoretic - they hitch rides on beetles and other insects to disperse to new habitats. Parasitic species include the varroa mite, the most devastating parasite of honey bees.

Economic and practical significance of the group

Predatory mesostigmatid mites are commercially produced for biological pest control. Phytoseiulus persimilis is one of the most widely sold biocontrol agents, used against spider mites in greenhouses worldwide - the market is worth hundreds of millions annually.

Recorded sources for this group: Biological control industry, bee health research. Imported estimates may describe particular regions or reporting periods.
