Each box contains cardboard strips with 5 cards each, wrapped in plastic, with parasitized whitefly pupae.
10 cardboard strips, hatching 3,000 parasitic wasps
50 cardboard strips, hatching 15,000 parasitic wasps
In case more points of introduction are required, half dose cards with 30 wasps per card are available
Use En-Strip for biological control of greenhouse whiteflies (Trialeurodes vaporariorum) and tobacco whiteflies (Bemisia tabaci) in the third and fourth larval stage. Use En-Strip preventively and at the first sign of pest presence.
Female adult parasitic wasps parasitize the third and fourth larval stage of the whitefly. Additionally, host feeding also occurs.
Optimal working conditions for En-Strip require a minimum 24 hour average greenhouse temperature of at least 17°C/63°F. At lower temperatures it is recommended to use the cards with half the amount of pupae.
Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Failure to do so can have a negative impact on their quality. In case you do need to store En-Strip, please follow the instructions below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer and/or under different conditions than recommended.
The information given below is merely indicative. Tailored advice can be provided if information is available on the local factors that need to be taken into account, such as the crop, the climate conditions and the level of infestation. For the correct approach, please consult a Koppert specialist or a recognized distributor of Koppert products.
