Effective against greenhouse whitefly and tobacco whitefly
What does EN-STRIP look like?
EN-STRIP contains pupae of the parasitoid Encarsia formosathat are glued on cardboard cards. Females have a dark brown to black head and thorax and a yellow abdomen. The males are completley black, but are rarely found. The parasitoid is about 0.6 mm in size. All developmental stages (except the adult stage) live within the host’s body (larvae or pupae of whitefly). Parasitized greenhouse whiteflies turn black halfway of the parasitoid development, while parasitized tobacco whiteflies turn brown.
How does EN-STRIP work?
The parasitoids emerge from the pupae that are glued on cardboard cards after several days at 20 °C. The parasitoids prefer third and fourth instar whitefly for oviposition. Smaller whitefly stages are preyed upon for host-feeding. This host-feeding is an important part of the control capabilities of this parasitoid. EN-STRIP is less effective when large amounts of honeydew are present or when plants are very hairy.
When can EN-STRIP be applied?
EN-STRIP is used in greenhouses and indoor plantings to control greenhouse whitefly (Trialeurodes vaporariorum) and tabocco whitefly (Bemisia tabaci). Consider multiple introductions. The product is sensitive to several chemical pesticides. Ask advice for deployment strategies.
