Use for
Pests
Greenhouse whitefly (Trialeurodes vaporariorum); Tobacco whitefly (Bemisia tabaci).
How it works
Mode of action
Adult female parasitic wasps parasitize the third and fourth larval stage of the whitefly. Additionally, host feeding also occurs.
Visual effect
Parasitized Trialeurodes vaporariorum pupae turn black, Bemisia tabaci pupae become brownish. Adult wasps leave the pupae via a round hole.

Directions for use
Application
- Open package carefully inside the greenhouse

Dosage
The dosage of En-Strip 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 until control is achieved. At increasing temperatures it may be better to switch to the use of Enermix or Ercal. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
Environmental conditions
The parasitic wasp is most effective at temperatures between 20°C and 25°C (68 and 77°F). At a 24 hours average temperature below 17°C/63°F the control of whiteflies may be insufficient.
Combined use
En-Strip 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).
