| Predatory mites can be distinguished from pest species by observing the speed of their movement. When disturbed, predators generally move quicker than pest mites. Predator abundance is strongly affected by pesticide use. |

Zetzellia mali has some tolerance for organophosphate and carbamate (Sevin) insecticides, but is susceptible to endosulfan (thiodan).
Z. mali are bright yellow with orange markings and a somewhat pointed posterior. |

Amblyseius fallacis adults (right) are tear-shaped, translucent, and very fast moving.
Agistemus fleschneri (left) adults are oval with a somewhat pointed posterior. They turn reddish-yellow upon feeding on pest mites.
Typhlodromus pyri (not pictured) is very similar in appearance to A. fallacis, but is slower moving. They are present in the tree canopy from April through September. |
