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.
Mode of action
Female adult parasitic wasp parasitizes the larva of the whitefly. Host feeding also takes place.
After 2-3 weeks, the first parasitized pupae can be seen in the crop. Parasitized pupae of Trialeurodes vaporariorum and Bemisia tabaci turn black and light brown in colour respectively. The adult parasitic wasp emerges from the pupa through a round hole.
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.
