Preferred food: sweet potato whitefly and silverleaf whitefly in greenhouse and outdoor crops. Wasps usually hatch within 1-2 days. Leave the cards in place for at least 10 days to allow all eggs to hatch. Eretmocerus can be stored at 40° F for 2-3 days if you do not release them immediately upon arrival. Application and Release rates: Release rates vary depending upon crop, infestation and season of the year. For prevention, use 1 parasite for 10 sq ft. For low infestations (less than 1 adult whitefly per 50-100 plants) release 1 parasite/sq ft weekly for a minimum of 5 weeks. For higher infestations, use 5 parasites/sq ft for a minimum of 5 weeks. Eggs are shipped on cards that can be hung directly on the plants. Release immediately upon receipt. Suspend the cards below plant tops. Cards can be put on stakes or hung from the edge of a pot. Do not touch the eggs or pupae. Do not hang them in direct sunlight. Place as close to whitefly populations as possible. Leave the cards in place for at least 10 days to allow all eggs to hatch. Look for parasitized whitefly pupae, easily distinguishable from unparasitized pupae. Overnight Shipping Required.
