Amblyseius montdorensis
Amblyseius montdorensis
Type
Predatory mite (generalist)
Target pests
- Thrips (larval suppression)
- Whitefly (eggs/young stages)
- Some suppression of other small soft-bodied pests
Best use
A preventative predator used in a very similar way to swirskii.
Particularly valuable where conditions are slightly cooler or less favourable for swirskii.
Key commercial distinction
- Amblyseius Swirskii is typically strongest in warm protected crops.
- Amblyseius montdorensis is often preferred in cooler conditions, early-season crops, or where light/temperature are lower.
Use in crops
- Ornamentals (early season)
- Soft fruit tunnels (cooler starts)
- Protected vegetables in spring
Notes
Montdorensis provides a strong baseline for thrips + whitefly suppression, often combined with Orius once flowering begins.

IPM positioning
Preventative predator for thrips and broad mite, particularly suited to warmer systems.
Best deployment strategy
- Use preventatively for thrips and broad mite, especially in warmer systems.
- Apply evenly; reinforce with top-ups during high pressure.
- Layer with Orius for improved thrips control once flowering begins.
Compatibility notes
- Works well with: Orius Laevigatus / Orius Majusculus for thrips.
- Works well with: parasitoids for whitefly where relevant.
Environmental preferences
- Generally suited to warmer greenhouse conditions.
- Stability of temperature and humidity improves establishment and persistence.
