Ervipar (Aphidius ervi) — Large Aphid Parasitoid Mummies
Ervipar contains the mummified aphid stage of Aphidius ervi, a powerful biological control agent for large aphid species. These mummies contain developing parasitoids that emerge as adults shortly after release. Once emerged, adult females seek out aphid colonies, lay eggs inside aphids, and stop feeding immediately. The developing parasitoid kills the aphid and continues the cycle. Ervipar is chemical-free and safe for use in any growing environment including greenhouses, nurseries, orchards, flower beds, interiorscapes, outdoor landscapes, indoor plants including houseplants and more.

High parasitism capacity — Each female can parasitize up to 300 aphids during her lifetime
Specialized targeting — Ideal for large-bodied aphid species such as potato aphid and glasshouse potato aphid

Use For
Targets large aphid species, including:

Potato aphid (Macrosiphum euphorbiae)
Glasshouse potato aphid (Aulacorthum solani)
Tobacco aphid (Myzus persicae var. nicotianae)

When to Use Ervipar
Use wherever large aphid species are present and fast, targeted biological control is needed.
Recommended for:
First sign of large aphid presence — introduce Ervipar as soon as potato or glasshouse aphids are detected
Hotspots and hard-to-reach areas — target growing tips, leaf folds, and protected zones sprays cannot penetrate
Low to high aphid pressure — apply higher rates and repeat introductions until colonies are suppressed

Choosing Between Aphipar, Aphipar-M, and Ervipar
Aphipar (A. colemani) — Best for small-bodied aphid species such as cotton aphid and green peach aphid in warm conditions
Aphipar-M (A. matricariae) — Best for varying aphid species such as tobacco and peach-potato aphids in cooler conditions
Ervipar (A. ervi) — Best for large-bodied aphid species such as potato aphid, glasshouse potato aphid, and tobacco aphid in moderate temperatures

How It Works
Mode of Action — Adults emerge from mummies and parasitize aphids by laying eggs inside them; the developing larva kills the aphid and forms a new mummy
Behavior — Parasitoids move actively through foliage, searching for aphid colonies
Visual Effect — Parasitized aphids turn tan or bronze and become mummies

Parasitism Timeline:
Adults begin emerging within 1–3 days of release
First new mummies appear in 10–14 days
Each female parasitizes up to 200 aphids during her lifetime
Adults live for ~10–14 days under optimal conditions

Application Notes:
Spread mummies on rockwool slabs or place in Diboxes
Keep material dry and undisturbed for several days
Avoid placing mummies directly on wet surfaces

Best Working Conditions
Temperature — Most effective between 68–77°F
Humidity — Moderate RH supports emergence and activity

Compatibility Guidance
Allow residues from oils or soaps to dry before application

Product Specifications
Pack Size — 500 mummies
Presentation — 100 mL bottle
Carrier — Buckwheat hulls
Appearance — Brown aphid mummies mixed with carrier

What to Expect
Adults emerge within 1–3 days; parasitized aphids turn into mummies in 10–14 days. New adults continue parasitizing aphids. Reapply based on scouting to maintain control and prevent resurgence.

Recommended IPM Pairings
Aphidend (Aphidoletes aphidimyza) — Rapid knockdown without mummy formation; complements Ervipar’s long-term parasitism
Aphipar or Aphipar-M — For smaller aphid species or mixed colonies
Isarid® Mycoinsecticide — Adds fungal mode of action for aphids and soft-bodied pests; fully compatible with parasitoids
Dune™ — Improves plant resilience against sucking pests, reducing overall aphid pressure
Horiver Yellow Sticky Traps — For monitoring winged aphids and secondary pests; essential for scouting
Essential Oil Knockdown (e.g., neem-based) — For pre-release reduction of heavy aphid populations; apply after residues dry
