Introduction

  • 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

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: 8-10°C/47-50°F
  • In the dark

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

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

Encarsia formosa
Female adults: black head, black thorax, yellow abdomen
Male adults: hardly appear
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 or black in colour dependent of the combination parasite/host. 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 or recognized distributor will be able to advise you further.
