Overview

Lacewings stay where you place the cards in your garden, and the larvae are voracious feeders on those pesky bugs. The larvae are voracious predators used to control a wide range of soft-bodied pest insects. Green Lacewings larvae eat aphids, mealybugs, spider mites, leafhopper nymphs, moth eggs, scale, thrips, and whiteflies. The best time to release is early morning or late afternoon. The cards can be stored at no lower than 50°F for up to 48 hours.

The eggs are on perforated hanging cards, hang the cards, from the hole in the card, near the underside of leaves in the target area.

Eggs: Green Lacewing eggs are oval and pale green. Just before the larvae hatch, eggs turn gray. The eggs are shipped in vials with food and a carrier such as rice hulls, bran or vermiculite. It is best to allow a few of the lacewing larvae to begin emerging from the eggs before releasing. As soon as a few emerge, release as soon as possible to avoid cannibalism. The best time to release is early morning or late afternoon. Eggs can be stored at no lower than 50°F for up to 48 hours. To minimize egg mortality, humidity should be approximately 75%. Warmer temperatures will speed up larval emergence, but the eggs should not be held at more than 80°F. For small areas, sprinkle the contents of the container(s) over the entire target area. For large areas you may need to mix eggs with additional inert ingredients such as vermiculite, bran, saw dust, etc. to help dispersal. You may also release eggs on every other row on alternating dates. 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. The adult lacewing lays her eggs on foliage where each egg is attached to the top of a hair-like filament. After a few days the eggs hatch and a tiny predatory larva emerges ready to eat some aphid pests. 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. Lifecycle 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. Each adult female may deposit more than 200 eggs. For best results, habitats should encourage the adults to remain and reproduce in the release area. Nectar, pollen, and honeydew stimulate their reproductive process. If these food sources are not available, adults may disperse. An artificial diet called Wheast is available to provide the adults with the necessary nutrition they need for reproduction. Wheast powder mixed with sugar and water is used at Beneficial Insectary to help mass-rear the lacewing. Studies by universities and the USDA have shown that spraying field crops with a Wheast/sugar/water mixture increases egg laying considerably. Green lacewing adults can survive the winter in protected places but have a difficult time surviving cold winters.

The Green lacewing larvae is the most beneficial stage with the lacewings. They feed on soft-bodied insects like aphids, but will also feed on caterpillars and some beetles. The biggest benefit of lacewing larvae is how aggressive they are. They will eat anything they can catch, and they are always hungry. They’re also cost effective, especially the eggs. They have the ability to quickly knock down moderate levels of aphid infestations, as well as help control many other pests.
