5P335L – Lacewings Chrysoperla rufilabris

Green lacewing (scientifically known as Chrysoperla rufilabris) is widely used in various situations to control many different pests. Many species of adult lacewings do not kill pest insects, they actually subsist on foods such as nectar, pollen and honeydew. It’s their predacious offspring that get the job done. If you’re looking for effective aphid control, green lacewing larva should help do the trick.

Lacewing larvae are tiny when emerging from the egg, but grow to 3/8 of an inch long. They’re known as aphid lions since they voraciously attack aphids by seizing them with large, sucking jaws and inject a paralyzing venom. The hollow jaws then draw out the body fluids of the pest, killing it. Of all available commercial predators, this lacewing is the most voracious and has the greatest versatility for aphid control in field crops, orchards, and greenhouses.Each green lacewing larva will devour 200 or more pests or pest eggs a week during their two to three week developmental period. After this stage, the larvae pupate by spinning a cocoon with silken thread. Approximately five days later adult lacewings emerge to mate and repeat the life cycle. Depending on climatic conditions, the adult will live about four to six weeks.

Larvae: Lacewing larvae are sold in bottles of 1,000. Containers have a limited supply of food, so the larvae must be used as soon as possible. Lacewing larvae are safe to humans and animals, but vigorously attack their prey. They are ideal for aphid control as each lacewing larva can devour 200 or more pests or pest eggs during the two- to three-week larval stage.

At 80° F, the green Lacewing eggs will hatch in about 4 days. They hatch with a voracious appetite. In fact, they are so hungry, they often resort to cannibalism if there is no other food source available. Lacewing larvae will attack almost any soft-bodied insect. They feed upon small worms, insect eggs, mites, immature whiteflies, etc. However, the larvae are best known for attacking aphids and each is capable of killing 30 to 50 aphids per day. Many aphids are eaten but many more are killed by being punctured by the Lacewing larvae. Each larvae will feed for about 3 weeks, then will roll up into a little white pupae and emerge as an adult in about 1 week ready to mate and lay about 100 more eggs. The adult Lacewing does not feed on aphids. The complete Lacewing life cycle takes 4 – 6 weeks.

   To prevent a high percentage of the Lacewing population from being in the pupal, adult or egg stage at the same time, it is recommended that two or three releases, two weeks apart, be made. Lacewing larvae are good general predators and will also feed on whitefly larvae and other plant pests. Release instructions are included with your order.
