Koppert Ercal (Eretmocerus eremicus)

Koppert Ercal is an exceptional product that's specially designed to help control whiteflies. The Eretmocerus eremicus, a type of parasitic wasp, specifically targets the second and third larval stage of tobacco whitefly (Bemisia tabaci) and glasshouse whitefly (Trialeurodes vaporariorum). Host feeding takes place when adult female wasp parasites the larva of the whitefly. You will see visible results after 2 weeks by the appearance of first parasitized pupae which will turn yellow in color and is independent of species. It's very easy to use; simply suspend the cards at approximately 75 cm under plant head or on plants that you want to protect from whiteflies. It is not recommended to be placed in areas with direct sunlight.

Koppert Ercal is available in two sizes:

  • The small box contains 3,000 Parasitic Wasps pupae on 50 cards, 60 wasps per card.
  • The large box contains 15,000 Parasitic Wasps pupae on 250 cards, 60 wasps per card.



  • 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 68F (20C). However introductions can start at lower temperatures.

At higher temperatures (above 86F/30C) Eretmocerus eremicus stays active.

Storage and handling

Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Storing them for a period can have a negative impact on their quality and is only possible under the conditions described below. 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 after receipt: 1-2 days
  • Storage temperature: 47-50F (8-10C)
  • 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
