Use for
Pests
Greenhouse whitefly (Trialeurodes vaporariorum); Tobacco whitefly (Bemisia tabaci).
How it works
Mode of action
Adult female parasitic wasps parasitize second to fourth stage larvae of the whitefly. Host feeding also takes place.
Visual effect
Trialeurodes vaporariorum pupae parasitized by Encarsia formosa turn black, Bemisia tabaci pupae become brownish. Whitefly pupae parasitized by Eretmocerus eremicus turn yellow, the adult parasitoid wasp can be seen clearly within the parasitized whitefly pupae shortly before it emerges.

Directions for use
Application
- Open package carefully inside the greenhouse
- Bend and tear off the strips opposite to the mounting hole
- Make sure not to touch the pupae during handling
- Suspend the cards in the crop, if possible approximately 75 cm under the plant head
- Avoid to hang cards at places exposed to direct sunlight
Dosage
The dosage of Enermix 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 Ercal. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
Environmental conditions
Encarsia formosa 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. For optimal performance of Eretmocerus eremicus 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.
Combined use
Enermix 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).
