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.

Introduction
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.
Remarks
Eretmocerus eremicus is less susceptible to pesticides than Encarsia formosa.
Intensive deleafing (in tomatoes) hinders the population build up of whitefly parasites.
Appearance
Female adults: lemon-yellow
Male adults: brownish-yellow, thick antennae
