Green Lacewing
Preferred food:
aphids, mealybugs, spider mites, leafhopper nymphs, caterpillar eggs, scales,
thrips, and whiteflies.
(Chrysopa carneca) For greenhouse, garden or orchard. The larva feeds on many
soft bodied insects including aphids, red spider mites, thrips, mealybugs, moth
eggs, leafhoppers, and others. Very small and gray-brown in color. The larva
feeds for two or three weeks when it then pupates.
The adult emerges one week later to feed on nectar, pollen, or honeydew. If
there is food for the adults then the life cycle will be repeated. If there is
not, then new larva releases will need to be made every three weeks.
1,000 per 500 sq. ft. 5,000 per acre.
The adults eat only honey, pollen, and nectar, which they need to reproduce.
Repeated releases may be necessary if the infestation has not been arrested 5-7
days after the larvae have emerged.
