Storage and handling

Koppert B.V. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions.

- Storage temperature: 8-10°C/47-50°F

Mode of action
Female adult parasitic wasp of Diglyphus isaea kills leaf-miner larva in the mine and lays an egg on it. The egg develops into a parasitic wasp inside the mine (but outside the leaf miner), using the dead larva as food. Host-feeding also takes place.
Two weeks after introduction it is possible to see parasitization. The presence of Diglyphus isaea is recognized by short/stopped mines containing a dead larva. Pupae of Diglyphus isaea can be seen when holding leaves up to the light.
