Aphelinus abdominalis – Broad-Spectrum Parasitic Wasp for Aphid Control
Aphelinus abdominalis – Broad-Spectrum Parasitic Wasp for Aphid Control
A dual-action wasp that parasitizes and eats aphids other parasitoids struggle with
Some large aphids, like potato and foxglove aphid, shrug off the usual parasitoids, and that is where Aphelinus abdominalis comes in. It works two ways at once: females lay eggs inside aphids and also feed directly on others, so you get parasitism plus immediate host-feeding mortality from one wasp. It thrives in warm conditions and lives longer than most Aphidius species, which makes it a strong choice for recurring, hard-to-shift aphid problems.
Live insects ship on Tuesdays only and arrive Wednesday. Orders must be placed 7 days in advance. Anything ordered by 3pm EST Tuesday ships the following Tuesday by UPS overnight shipping.
- Large aphids resist many standard parasitoids
- Parasitism alone can be slow to show
- Most parasitoids are short-lived
- Sprays leave residue and harvest timing
- Broad products harm other beneficials
- Reactive only
- Built for the large, stubborn species others miss
- Also host-feeds for an immediate cut in numbers
- Lives longer than most Aphidius species
- No residue, no re-entry interval
- Selective wasp spares your other biocontrol
- Ideal for recurring, chronic aphid pressure
Two ways to kill aphids Parasitizes + host-feeds
Females both lay eggs inside aphids and feed directly on others, so you get parasitism plus immediate host-feeding mortality, giving higher overall kill than parasitism alone.
Made for the tough species
Aphelinus targets large aphids like potato and foxglove or glasshouse aphid, the species that are less responsive to other parasitoids.
Longer-lived adults
It lives longer than most Aphidius wasps, so each release keeps working the colony for an extended stretch, which suits chronic problems.
Distinctive mummies
Parasitized aphids swell into gray or brown mummies as the larva develops, giving you a clear visual sign the wasps are established.
Thrives in warm rooms
It performs best in warm conditions, making it well matched to indoor grow rooms and greenhouses running recurring aphid pressure.
Self-perpetuating
Adults chew out of the mummies and continue the cycle, so repeated releases build an on-site defense over time.
Release the mummies right at infested plants, since the adults do not travel far.
Spread the material on slabs or in release boxes; keep it dry for a few days.
Typical rate 0.25-4 per m²; repeat several times.
Holds up better than Aphidius wasps in hot conditions.
How Aphelinus clears stubborn aphids
Release near the colonies
Set out the container among the plants near large-aphid clusters, out of direct light and drip.
Wasps parasitize and feed
Females lay eggs inside some aphids and feed directly on others, killing pests two ways at once.
Aphids become mummies
Parasitized aphids swell into gray or brown mummies as the wasp develops inside.
Wasps keep working
Long-lived adults emerge and continue the cycle, so a release presses a chronic colony for an extended period.
