Amblyseius swirskii

Type

Predatory mite (generalist)

Target pests

• Thrips (larvae suppression)
• Whitefly (egg/young stages)
• Broad Mite (suppression)

Best conditions

• Performs well in warm protected crops
• Works best preventatively or early in infestations

Use in crops

• Peppers
• Chillies
• Cucumbers
• Ornamentals Hub crops

Notes

Swirskii is a foundational preventative predator in many commercial greenhouse IPM programmes. Often introduced early and supported with top-ups as pest pressure changes.

Related principles

• Biological Control Top Ups
• Avoid Broad Spectrum Sprays

IPM positioning

Preventative multi-pest predator for thrips, whitefly and broad mite; strong establishment species.

Best deployment strategy

• Introduce early as a preventative predator where thrips/whitefly/broad mite risk is expected.
• Aim for even distribution and continuity (top-ups during rapid growth or high pressure).
• Combine with parasitoids (e.g. for whitefly) for layered control.

Compatibility notes

• Works well with: Encarsia Formosa / Eretmocerus Eremicus (parasitoids) for layered whitefly control.
• Works well with: Orius Laevigatus / Orius Majusculus for thrips programmes.

Environmental preferences

• Strong performer in warmer conditions; establishment improves with warmth.
• Can struggle if conditions are consistently cool.
• Performs best with stable climate and availability of prey/alternative food.
