Aphidius ervi

Type

Parasitoid wasp

Target pests

• Aphids

Best use

Often stronger on larger aphid species in soft fruit systems.

Notes

Key tool in raspberry and tunnel crops.

IPM positioning

Curative parasitoid targeting larger aphid species. Often complementary to A. colemani.

Best deployment strategy

• Use where larger aphid species are present or expected.
• Combine with A. colemani for mixed aphid complexes.
• Maintain continuity with repeat introductions during flushes of soft growth.
• Avoid broad-spectrum insecticide residues.

Compatibility notes

• Works well with: Aphidius colemani for mixed aphid complexes; predators (ladybirds/lacewings) as clean-up.
• Avoid: broad-spectrum insecticides and disruptive residues.

Environmental preferences

• Generally suited to moderate conditions and can perform well in cooler crops compared with some other aphid parasitoids.
• Stable climate supports consistent parasitism rates.
