Green Lacewing Adults Chrysoperla - Aphid Control



Green Lacewing Adults are ideal to be used on large crops where lacewing eggs and larvae are not easily released. Adults will fly and lay eggs near the aphid-infested plants.

TARGET PESTS: Aphids, Small Caterpillars, Whiteflies, Mites, Scale, Thrips, Psyllids, Mealybugs and other soft-bodied insects and their eggs.

DESCRIPTION: Green Lacewings are general predators that feed on a variety of insects. They are very effective on aphids.  During the larval stages, it is a predator. Adults are large green insects with large, almost transparent lace-like green wings. Larvae are small alligator-looking critters with conspicuous legs.  They move from plant to plant on leaves. Larvae pupate on upper leaf surfaces, plant stems, and twigs. Eggs are laid on hair-like filaments – up to 600 eggs per adult.


Light Infestation: 100 adults per 4,000 sq.ft.

Medium/High Infestation: 100 adults per 2,000 sq.ft.

Orchards: 100-1,000 adults per acre. depending on infestation.

LIFESPAN: Egg to adult:  about 30 days depending on the weather.  Adults live for 20-40 days and will lay 10-30 eggs/day and up to 600 eggs on hair-like filaments.  Lacewing eggs hatch in about 3-5 days after reaching a temperature of about 60 °F.  Larvae are predators for 2 weeks or longer if the nights are cool.  During 2-3 larval stages, one solitary Lacewing can kill 300-400 aphids, 11,000 spider mites, 3,700 scale crawlers, or 6,000 scale eggs. Cocoons yield adult Lacewings in about 5 days. The adult Lacewing will migrate toward pollen, insect honeydew, or nectar before laying eggs. Temperature and food availability will determine the timing of each stage and reproductivity.

STRATEGIC CONSIDERATIONS: Pesticides and even-wetting agents and spreader-stickers may adversely affect Lacewing survival.  Broad spectrum and systemic insecticides are toxic to Lacewings
