Phytoseiulus persimilis

Type

Predatory mite

Target pests

• Spider Mites

Best use

Curative specialist predator for rapid spider mite knockdown.

Notes

Performs best with sufficient humidity and early release.

IPM positioning

Highly curative specialist predator for spider mite; requires active infestation.

Best deployment strategy

• Use curatively at first sign of spider mite (do not wait for heavy webbing).
• Place onto infested plants and surrounding buffer zones to prevent spread.
• Follow with supportive predators (Amblyseius spp.) for longer-term stability if needed.

Compatibility notes

• Works well with: supportive predatory mites (Amblyseius Swirskii, Amblyseius Cucumeris) where longer-term stability is needed.
• Note: as a specialist, performance drops quickly once spider mite prey is exhausted (may require follow-up strategy).

Environmental preferences

• Performs strongly in moderate to warm, humid conditions.
• Hot/dry conditions can reduce performance; maintaining suitable humidity improves control.
