Product Details
Enermix (Encarsia formosa + Eretmocerus eremicus) — Parasitic Wasp Cards
Enermix contains a mix of two parasitic wasp species—Encarsia formosa and Eretmocerus eremicus—used for biological control of greenhouse and tobacco whiteflies. By combining two specialist parasitoids—Enermix covers both greenhouse and tobacco whiteflies, ensuring effective control even if you’re unsure of the species. These wasps parasitize whitefly larvae and also feed directly on them, providing layered suppression. Enermix is chemical-free, IPM-compatible, and safe for use in greenhouses, nurseries, interiorscapes, outdoor landscapes, and indoor crops including ornamentals, vegetables, fruiting plants, cannabis and more.
Key Features
Dual action — Combines parasitism and host feeding for layered suppression
Broad adaptability — Effective across a wide temperature range
Use For
Targets whitefly species including:Greenhouse whitefly (Trialeurodes vaporariorum)
Tobacco whitefly (Bemisia tabaci)
When to Use Enermix
Use preventively or at the first signs of whitefly presence. Effective across all growing environments.
Recommended for:
First sign of whitefly colonies — introduce Enermix early for fast suppression
Hotspots and hard-to-reach areas — leaf undersides and dense foliage where sprays cannot penetrate
Moderate to high whitefly pressure — apply higher rates and repeat introductions until colonies are suppressed
How It Works
Mode of Action — Adult females parasitize second to fourth stage whitefly larvae; host feeding also occurs
Behavior — Wasps actively search for whitefly larvae and deposit eggs inside them
Visual Effect:
Encarsia formosa turns T. vaporariorum pupae black
Eretmocerus eremicus turns B. tabaci pupae yellow or brownish
Adult wasps visible inside pupae shortly before emergence
Lifecycle of Encarsia formosa & Eretmocerus eremicus
Egg & Larval Stage — Eggs hatch inside whitefly larvae; larvae consume internal tissues and pupate within the host
Pupal Stage (included in Enermix) — Pupae visible inside parasitized whitefly pupae; development lasts ~10–14 days before adult emergence
Adult Stage — Adults are ~1 mm long; Encarsia formosa is black with a yellow abdomen; Eretmocerus eremicus is yellow; females parasitize multiple hosts daily; lifespan ~10–14 days under optimal conditions
Release Rates & Application
Pressure Level Definition Rate per 10 sq ft Repeat Interval Preventative Risk present; no visible colonies 1–2 cards Every 2–3 weeks Low Pressure Early colonies; minimal honeydew 2–4 cards Weekly Medium Pressure Multiple zones; visible honeydew 4–6 cards Weekly High Pressure Widespread colonies; heavy honeydew 6–10 cards Weekly or twice weekly in hotspots
Application Notes:
Open package carefully inside the greenhouse
Bend and tear off strips opposite the mounting hole
Do not touch pupae during handling
Suspend cards in the crop, ideally ~75 cm below the plant head
Avoid placing cards in direct sunlight
Repeat releases weekly until control is achieved
Best Working Conditions
Temperature —
Encarsia formosa: Optimal 68–77°F; less effective below 63°F
Eretmocerus eremicus: Active above 68°F and effective even above 86°FHumidity — Moderate to high RH supports emergence and activity
Compatibility Guidance
Allow residues from oils or soaps to dry before application
For pesticide/chemical compatibility details, check our Natural Enemies – Chemical Compatibility and Beneficial Insect & Pesticide Compatibility Table
Product Specifications
Pack Size — 3,000 or 15,000 pupae
Presentation — Cardboard strips (5 cards per strip), each card holds 60 parasitized whitefly pupae (30 E. formosa, 30 E. eremicus)
Developmental Stage — Pupae
Carrier — None
Storage & Handling
Store at 47–50°F in the dark
Use within 1–2 days of receipt
Do not refrigerate
Keep cards sealed until placement
What to Expect
Adults begin emerging within 1–3 days; parasitized whitefly pupae turn black, yellow, or brown depending on species. New adults emerge and continue parasitizing whiteflies. Reapply based on scouting observations to maintain control and prevent resurgence.
Recommended IPM Pairings
Swirski-Mite, Limonica, or Thripex— For complementary whitefly and thrips suppression
Isarid® Mycoinsecticide — Adds fungal mode of action for whiteflies and other soft-bodied pests
Dune™ — Improves plant resilience against sucking pests, reducing overall pest pressure
Horiver Yellow Sticky Traps — For monitoring adult whitefly movement
Essential Oil Knockdown (e.g., neem-based) — For pre-release reduction of heavy whitefly populations; apply after residues dry
FAQs
Does Enermix kill whiteflies immediately?
No—Enermix works through parasitism and host feeding. Adults emerge within 1–3 days, parasitize second to fourth stage whitefly larvae, and feed directly on them. Visible color changes in pupae occur within 10–14 days.
Does Enermix contain adults?
No—Enermix contains pupae. Adults emerge under optimal conditions (68–77°F for E. formosa, active above 68°F for E. eremicus) and begin parasitizing immediately.
How soon will I see results?
Emergence begins within 1–3 days of placement. Parasitism becomes visible within 10–14 days. Adults live for 10–14 days under optimal conditions, ensuring sustained activity.
Can I use Enermix with other beneficials?
Yes—Enermix integrates well into IPM programs. It can be combined with predatory mites for layered control. Always allow residues from oils or soaps to dry before release and check compatibility charts for chemical sprays.
Is Enermix safe for all plants & crops?
Yes—Enermix is safe for use on all crops, plants and growing environments.Questions about Enermix?
