Abstract: Green lacewings Chrysoperla species are an exceptional addition to any integrated pest management program, thus purpose of this paper is to assess mass-production and field applications for augmentative biological control of insect pests. Lacewing larvae are voracious eaters of eggs and immature stages of many soft bodied insect pests including several species of aphids, spider mites, thrips, whiteflies, leafhoppers, some beetle larvae, eggs and caterpillars of pest moths, and mealybugs. This tiny magnificence is wonderful and cost effective additions to any pest control program as each green lacewing larva can devour 200 or more pests or pest eggs in a week during their two to three weeks developmental period. Growers wanted to establish green lacewings should applicate at the beginning of plant season or while have a limited pest’s infestation and choose appropriate numbers of eggs for field, garden or greenhouse releases. When there have a moderate to severe pest infestation, deliver an appropriate number of eggs or larvae weekly or biweekly preferably every 7-10 days for at least 3 times to ensure a continual supply of predators. For best results, habitats should be encouraged for adults to remain and reproduce in the released area by providing nectar, pollen and honeydew nutrition to stimulate their reproductive process.
