Diglyphus isaea

Diglyphus isaea is a specialist. It is the gold standard for:

• Leafminers: It targets the larval stage inside the leaf "mines."
• Secondary Benefit: Adult wasps perform "host-feeding," where they puncture leafminer larvae to consume their body fluids, killing the pest even if they don't lay an egg.

To ensure these high-performance wasps remain active, maintain these conditions:

• Temperature: Performs best between 20°C – 26°C. Activity decreases significantly below 15°C.
• Lighting: Being diurnal, they require good light levels to navigate and find hosts.
• Habitat: Best used in environments where leaf damage is already visible, as the wasps find their prey by detecting the "mines" in the leaves.

Choosing Diglyphus isaea is the strategic choice for leafminer management for several reasons:

• Surgical Precision: Generalist predators like Lacewings or Mites cannot reach pests protected inside the leaf tissue. Diglyphus is the only "surgical" option that penetrates the leaf mine to eliminate the pest at the source.
• Aroid Aesthetics: For plants like Monstera, Alocasia, or Philodendron, leafminer damage is permanent and ruins the plant’s value. Diglyphus stops the expansion of white trails immediately upon parasitism.
• Rapid Population Growth: In warm indoor environments, Diglyphus can build up a population faster than the leafminers can reproduce, quickly bringing an outbreak under control.

1. Release Point: Release the wasps directly at the "hot spots" where leafminer trails are most visible.
2. Application: Gently open the bottle and let the wasps fly toward the plants. You can walk through the area, lightly tapping the bottle to distribute them evenly.
3. Timing: Release in the early morning or late afternoon. Avoid releasing during the heat of the day or when exhaust fans are at maximum speed.
4. Dose per 6" Plant: For a curative measure on plants with active mines, we recommend 1–2 wasps per 6" plant.

Format: Shipped as adult wasps ready to hunt and parasitize immediately.

Packaging: Specialized tubes designed to keep the wasps calm and viable during transit.

Storage: These are highly active insects. Release immediately upon arrival. If storage is unavoidable, keep at 8°C – 10°C for no more than 1 hour.

No. Diglyphus isaea is a "micro-wasp." They are biologically programmed to only seek out leafminer larvae and have no interest in humans or animals. They do not have a defensive sting.

The most immediate sign is that the leafminer "mines" stop growing. If you look closely at a mine under a hand lens, you may see the paralyzed leafminer larva. Eventually, the Diglyphus pupates inside the mine, appearing as a small dark object.

We recommend removing yellow sticky traps for 48 hours during the initial release, as the wasps are attracted to the color. Once they have settled into the canopy, you can replace the traps, but hang them at least 12–18 inches above the plants.

If leafminers are present, Diglyphus will reproduce. A new generation of wasps emerges every 10–14 days. If the food source (leafminers) is completely eliminated, the wasps will eventually die off or move on.

Diglyphus is a highly specialized, lab-reared predator. Because they provide a unique "surgical" service that generalists cannot (killing pests inside the leaf), they are a premium tool for saving the aesthetic value of rare plants.

Absolutely. Since Diglyphus works inside the leaf and Lacewings/Mites work on the leaf surface, they occupy different niches. Combining them provides a "Total Canopy Defense" against multiple pest types.
