Product Details
Aphidend (Aphidoletes aphidimyza) — Gall Midge Pupae
Aphidend contains the pupal stage of Aphidoletes aphidimyza, a predatory gall midge used for biological control of aphids. Once adults emerge, females seek out aphid colonies and lay eggs directly within them. The emerging larvae paralyze and consume aphids entirely, leaving only the skin behind. Aphidend is chemical-free, IPM-compatible, and safe for use in greenhouses, nurseries, interiorscapes, outdoor landscapes, and indoor crops including ornamentals, vegetables, fruiting plants, and cannabis.Key Features
Rapid knockdown — Larvae feed aggressively on all aphid stages, reducing populations quickly
Broad-spectrum targeting — Effective against multiple aphid species in greenhouse and field cropsUse For
Targets a wide range of aphid species, including:Green peach aphid (Myzus persicae)
Cotton aphid (Aphis gossypii)
Potato aphid (Macrosiphum euphorbiae)
Foxglove aphid (Aulacorthum solani)
Tobacco aphid (Myzus persicae var. nicotianae)
Other greenhouse and field aphidsWhen to Use Aphidend
Use as soon as aphid colonies appear. Effective across all growing environments and especially valuable in dense foliage and humid conditions where aphids reproduce rapidly.
Recommended for:
First sign of aphid colonies — introduce Aphidend early for fast suppression
Hotspots and hard-to-reach areas — growing tips, leaf folds, and protected zones sprays cannot penetrate
Moderate to high aphid pressure — apply higher rates and repeat introductions until colonies are suppressedHow It Works
Mode of Action — Adults emerge from pupae and deposit eggs directly into aphid colonies; larvae hatch, paralyze, and consume aphids
Behavior — Adults are nocturnal and locate aphid colonies by scent and honeydew; larvae feed aggressively on all aphid stages
Visual Effect — Aphids are consumed entirely—only the skin remainsFeeding Rates:
Larvae consume 4–65 aphids per day depending on prey density and environmental conditions
Feeding begins immediately after hatching and continues for 3–7 days before pupation
Larvae may kill more aphids than they consume when populations are highLifecycle of Aphidoletes aphidimyza
Egg Stage — Shiny orange-red eggs laid directly in aphid colonies; hatch in 2–3 days under optimal conditions
Larval Stage (predatory) — Orange-brown, legless larvae up to 3 mm long; feed aggressively for 3–7 days
Pupal Stage (included in Aphidend) — Black pupae mixed with wood fiber carrier; hatch into adults under warm, humid conditions
Adult Stage — Small black midges with long legs; active at night; females lay eggs in aphid coloniesRelease Rates & Application
Pressure Level Definition Rate per 10 sq ft Repeat Interval Preventative Risk present; no visible colonies 1–2 pupae Every 2–3 weeks Low Pressure Early colonies; minimal honeydew 5–10 pupae Weekly Medium Pressure Multiple zones; visible honeydew 10–20 pupae Weekly High Pressure Widespread colonies; heavy honeydew 20–40 pupae Weekly or twice weekly in hotspots Application Notes:
Open the bottle directly in the greenhouse
Place bottle on soil, rockwool slabs, or hang between plants using a Biotag
Do not scatter contents—pupae must remain in the bottle to maintain humidity
Adults hatch and leave the bottle to spread naturally
One 500 mL bottle covers ~3,000 sq ft and introduces at least 3 midges per sq ft
Use peel-off label to mark release points
Repeat weekly until control is achievedBest Working Conditions
Temperature — Most effective between 68–86°F
Night Temperature — Must remain above 61°F for optimal oviposition
Humidity — High RH (>70%) supports emergence and egg-layingCompatibility Guidance
Allow residues from oils or soaps to dry before application

Pack Size — 1,000 or 10,000 pupae
Presentation — 100 mL or 500 mL bottle
Carrier — Wood fiber
Appearance — Black pupae mixed with carrier; larvae are orange-brown and leglessStorage & Handling
Store at 50–59°F in the dark
Use within 1–2 days of receipt
Keep containers closed until release; acclimate briefly before distribution
Store horizontallyWhat to Expect
Adults begin emerging within 24–48 hours; larvae start feeding immediately after hatching. Aphid populations are actively suppressed as larvae consume colonies. Results build quickly in hotspots and continue as larvae move through affected areas. Reapply based on scouting observations to maintain control and prevent resurgence.Recommended IPM Pairings
Aphipar, Aphipar-M, or Ervipar — For layered suppression and mummy formation
Isarid® Mycoinsecticide — Adds fungal mode of action for aphids and other soft-bodied pests
Dune™ — Improves plant resilience against sucking pests
Essential Oil Knockdown (e.g., neem-based) — For pre-release reduction of heavy aphid populations; apply after residues dryFAQs
Does Aphidend kill aphids immediately?
No—Aphidend works through larval feeding. Adults emerge within 24–48 hours, lay eggs in aphid colonies, and larvae begin feeding immediately after hatching. Aphids are paralyzed and consumed entirely, leaving only the skin behind.
Does Aphidend contain adults?
No—Aphidend contains pupae. Adults hatch under warm, humid conditions and begin laying eggs in aphid colonies.
How soon will I see results?
Feeding begins within 24–48 hours of hatching. Larvae consume 4–65 aphids per day depending on prey density and environmental conditions. Visible reduction in aphid populations occurs rapidly in hotspots.
Can I scatter the pupae over the crop?
No—pupae must remain in the bottle to maintain humidity. Scattering reduces emergence and effectiveness.
Can Aphidend be used with parasitoids?
Yes—Aphidend complements Aphipar, Aphipar-M, and Ervipar for layered aphid control. Always allow residues from oils or soaps to dry before release and check compatibility charts for chemical sprays.Questions about Aphidend?
