Miglyphus - 500ct. Bottle

Miglyphus (Diglyphus isaea) — Targeted Leaf Miner Control
Miglyphus bottles contain active life stages of Diglyphus isaea, a specialist parasitoid for controlling leaf miner larvae. Miglyphus flies to locates leaf miner larvae and combines two strategies for control: adults pierce and feed on the larva’s fluids for nutrition (host feeding), while females lay eggs beside the killed larva so developing wasps can consume the host remains (parasitism). Miglyphus 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.

Immediate Action
Adult females kill larvae and feed for rapid control
Combines host feeding with parasitism for layered impact
Targets leaf miner hotspots for efficient population reduction

Miglyphus Targets
Leaf miner larvae (Liriomyza spp. and related species)

When to Use Miglyphus
Use wherever leaf miners are expected or present. Effective across all growing environments.
Recommended for:
• Preventative coverage to stop leaf miners before larvae establish inside leaves
• Early-stage pest presence
• Hotspots or wide-spread issues requiring sustained biological control
• Plants with dense foliage or layered canopy structures where pests hide deep in leaf tissue
• Growers seeking long-term prevention & control

How It Works
Mode of Action: Adult females pierce and kill leaf miner larvae and lay eggs adjacent to the host
Behavior: Larvae develop into parasitic wasps inside the leaf, feeding on host remains
Visual Effect: Tunnels shorten and contain dead larvae; pest pressure declines as parasitoids establish
Application Method: Release wasps between crop leaves in the morning or evening, focusing on hotspots

Feeding & Parasitism Rates
Adults kill multiple larvae daily through host feeding
Each female lays 50–100 eggs during its lifespan
Host feeding and parasitism combined deliver rapid population control

Lifecycle of Diglyphus isaea
Egg Stage
Laid beside killed leaf miner larvae
Hatch in 2–3 days under optimal conditions
Larval Stage
Develop inside the leaf, feeding on host remains
Pupal Stage
Occurs within the leaf; adult emerges after ~10 days
Adult Stage
Lifespan ~10–14 days
Actively hunts and parasitizes larvae

Release Rates & Placement

Application Notes:
Release between crop leaves in shaded conditions
Focus on areas with visible tunneling or known hotspots
Repeat releases at least 3 times or until control is achieved

Best Working Conditions

FAQs

Can I store this for later?
Long-term storage, i.e. more than 48 hours, is not recommended. Apply promptly after receipt. Our products are shipped fresh for immediate use to ensure maximum performance. If needed, keep in a cool, dark, dry place for up to 1–2 days; longer holding reduces effectiveness and quality.

What pests does Miglyphus target?
Leaf miners, especially Liriomyza spp., through host feeding and parasitism

How do I know it’s working?
Look for shortened tunnels containing dead larvae and reduced leaf miner activity

Can I use Miglyphus in low temperatures?
Miglyphus is less effective below 68°F; adjust release timing or use additional IPM strategies for cooler conditions.

Why choose beneficial predators?
Beneficial predators provide a sustainable, long-term approach to pest control:

• No resistance issues: Pests cannot develop resistance to natural predators, eliminating the constant cycle of switching chemical products.
• Easy to scale: As plants grow, predator introductions can be increased without overhauling the program, ensuring consistent results and minimal disruptions.
• Cleaner and safer: Replacing chemical sprays reduces pesticide runoff, protects pollinators, and promotes a more natural growing system.
• Superior quality: At Natural Enemies, we are the insectary. Products are held to the highest standards, ensuring vigorous, effective predators that perform reliably in real-world growing conditions.
