Adult female parasitic wasps parasitize the second and third larval stage of the whitefly. Additionally, host feeding also occurs.
Parasitized whitefly pupae turn yellow, the adult parasitic wasp can be seen clearly within the parasitized whitefly pupae shortly before it emerges.

| Presentation | Cardboard strips with 5 cards each, wrapped in plastic, in a cardboard box, each card holds 60 parasitized whitefly pupae. |

The dosage of Ercal depends on climate, crop and whitefly density and should always be adjusted to the particular situation. Start introduction preventively soon after planting of the crop. Introduction rates typically range from 1-10 per m2/release. Releases should be repeated at least 3 times at weekly intervals or until control is achieved. Depending on the specific situation, it may be better to switch to the use of En-strip or Enermix. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
For optimal efficacy the 24 hour average greenhouse temperature needs to be at least 20°C/68°F. Eretmocerus eremicus is still active at temperatures above 30°C/86°F.
Ercal is best to be used in combination with generalist predatory mites (Amblyseius andersoni, Amblyseius swirskii, Neoseiulus cucumeris or Amblydromalus limonicus) or, in tomato, with predatory mirid bugs (Macrolophus pygmaeus or Nesidiocoris tenuis).
Apply as soon as possible after receipt. If necessary, the product can be stored for 1-2 days.
8-10°C/47-50°F.
In the dark.
