Target : Greenhouse whitefly (Trialeurodes vaporariorum) and sweet potato whitefly (Bemisia tabaci) in the third larval stage.


  • open package carefully inside the greenhouse
  • bend strips and tear off. Start tearing opposite hang-up hole
  • suspend the cards in the crop, if possible approximately 75 cm under plant head
  • not in direct sunlight
  • do not touch the pupae

Environmental conditions

  • Eretmocerus eremicus performs best at a 24 hour average greenhouse temperature greater than 20°C/68°F. However introductions can start at lower temperatures.
  • At higher temperatures (above 30°C/86°F) Eretmocerus eremicus stays active.

Storage and handling

  • storage after receipt: 1-2 days
  • storage temperature: 8-10°C/47-50°F
  • in the dark


  • Eretmocerus eremicus is less susceptible to pesticides than Encarsia formosa.
  • Intensive deleafing (in tomatoes) hinders the population build up of whitefly parasites.


  • Female adults: lemon-yellow
  • Male adults: brownish-yellow, thick antennae
  • Other stages: develop inside host

Mode of action:  Female adult parasitic wasp parasitizes the larva of the whitefly. Host feeding also takes place.

Visual effect:  After about 2 weeks, the first parasitized pupae can be seen in the crop. The parasitized whitefly pupa turns yellow in colour and is independent of species. The adult parasitic wasp emerges from the pupa through a round hole.Important.

The introduction rates of this product should be adjusted to the mode of action of the product and the results that can be expected in the crop where the product is applied. Your local Koppert consultant will be able to advise you further.
