Amblyseius fallacis and Typhlodromus pyri , Phytoseiid predator mite species European red mites and twospotted spider mites. A. fallacis is a fast moving, yellow mite about the size of ERM, that moves back into trees in mid-summer. Where abundant, it can provide effective pest mite control.
Adults are lemon yellow.
Feeding pattern complements predation by Phytoseiid predators as they prefer different ERM stages. All spider species are predators, primarily on insects. Leafhoppers, leafminer larvae, and many other apple pests are probably preyed upon by spiders. The role of spiders in orchard pest regulation is not yet well understood.
