Preferred Scientific Name; Chrysoperla rufilabris. Taxonomic Tree; Domain: Eukaryota; Kingdom: Metazoa; Phylum: Arthropoda; Subphylum: Uniramia; Class. Green lacewings, Chrysoperla rufilabris are used as one of the most aggressive predators for controlling aphids, whiteflies, scale insects and mealy bugs. Despite its beautiful, poetic name, the green lacewing (Chrysoperla rufilabris) is deadly to almost any soft-bodied insect pest and its eggs. In its adult stage.

Relative Effectiveness These lacewing larvae are considered generalist beneficials but are chrysoperla rufilabris known as aphid predators. The larvae are sometimes called aphid lions, and have been reported to eat between and aphids each, although they may have difficulty finding prey in crops with hairy or sticky leaves.

Chrysoperla rufilabris

Natural populations of Chrysoperla have been recorded as important aphid predators in potatoes, but mass releases of chrysoperla rufilabris have yet to be evaluated against aphids in commercial potato production.

In small scale experiments outside the United States, lacewings achieved various levels of control of aphids on pepper, potato, tomato, and eggplant, and have been used against Colorado potato beetle on potato and eggplant.

On corn, peas, cabbage, and apples, some degree of aphid control chrysoperla rufilabris obtained but only with large numbers of lacewings.

Mass releases of C.

Several strains of C. Matching of the proper strain to specific pest management situations is desirable. Populations tolerant of pyrethroids, organophosphates, and carbaryl have chrysoperla rufilabris selected in the laboratory.

Green Lacewing — Chrysoperla rufilabris

Conservation Because young larvae are susceptible to dessication, they may need a source of moisture. Adult lacewings need nectar or honeydew as food before chrysoperla rufilabris laying and they also feed on pollen. Therefore, plantings should include flowering plants, and a low level of aphids should be tolerated.

Artificial foods and honeydew substitutes are available commercially and have been used to enhance the number and activity of adult lacewings.

These products may provide sufficient nutrients to promote egg laying, but they cannot counter the dispersal behavior of newly emerged adult lacewings. For general information about conservation of natural enemies, see Conservation in the Tutorial section on this site, Feature Article on conservation in Volume II, No.

Larvae are likely to remain near the release site if aphids or other prey are available. Newly emerging adults, however, will disperse in search of food, often over great distances, before chrysoperla rufilabris eggs.

Depending on climatic conditions, the adult will live chrysoperla rufilabris four to six weeks. Each adult female may deposit more than 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 chrysoperla rufilabris. An artificial diet called Wheast is available to provide the adults with the necessary nutrition they need for reproduction.
