Product Overview

Koppert En-Strip Small (202) is a unique product that's specially designed to help control whiteflies. The Encarsia formosa, a type of parasitic wasp, specifically targets the third and fourth larval stage of glasshouse whitefly (Trialeurodes vaporariorum) and tobacco whitefly (Bemisia tabaci), and even sweetpotato and silverleaf whitefly to some extent. Host feeding takes place when adult female wasp parasites the larva of the whitefly. You will see visible results after 2-3 weeks by the appearance of first parasitized pupae of glasshouse and tobacco whitefly which will turn black and light brown in color. 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 En-Strip is available in two sizes:

The small pack comes with 3000 Encarsia formosa pupae (parasitic wasps) on 50 cards.
The large pack comes with 15,000 Encarsia formosa pupae (parasitic wasps) on 250 cards.

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

Environmental conditions

The 24 hour average temperature in the greenhouse should be at least 63F (17C). At lower temperatures it is recommended to use the cards with half the amount of 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: maximum 1-2 days
Storage temperature: 47-50F (8-10C)
In the dark

Remarks

The black (empty) pupae remain on the card after hatching
Intensive deleafing (in tomatoes) hinders the population build up of whitefly parasites

Appearance

Female adults: Black head, black thorax, yellow abdomen
Other stages: develop inside host

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.
