Greenhouse Whitefly Control with Encarsia formosa - Whitefly Parasite
Preferred food: Greenhouse Whitefly (Trialeurodes vaporariorum) and limited control of sweet potato whitefly (Bemisia tabaci).
Life cycle and shipment: Shipped on 3 strips (5 cards on each strip) that contain parasitized whitefly scale and more than 1,000 Encarsia eggs. Encarsia do well in humidity of 50-70% and temperatures between 64º – 84º F. Adults will emerge from the pupae over a period of 1-2 weeks. They are active for about 10 days. Encarsia formosa will kill approximately 125 whitefly per week by using them for food or parasitizing them. The next generation of wasp develops inside the whitefly scale and emerges after 20 days.
Release Encarsia at the first sign of whitefly by hanging individual cards on plant foliage. Release rates vary depending upon crop, infestation and season of the year.
For greenhouse tomatoes and peppers, 1 strip per 4 plants weekly for 8-10 weeks; cucumbers, one per 2 plants weekly for 8-10 weeks; poinsettias, two per each plant weekly for 8-12 weeks. For each acre release 3,000 Encarsia weekly, for 8-10 weeks.
For prevention: Use 500-1,000/15,000 sq. ft. weekly.
For low infestations: (less than 1 adult whitefly per 50-100 plants) release 1,000-2,000 / 5,000-10,000 sq. ft. for a minimum of 3 weeks or until control is achieved.
For higher infestations: Use 3,000 / 3,500 sq. ft. for a minimum of 3 weeks or until control is achieved. Weekly Ship Programs also available
