The dynamics of predation by the green lacewing Chrysoperla externa Hagen (Neuroptera: Chrysopidae) on Enneothrips flavens Moulton (Thysanoptera: Thripidae) was investigated by placing embryonated eggs and first-instar larvae of C. externa on potted peanut plants (Arachis hypogaea L.; Fabales: Fabaceae) in a greenhouse. The plants that received either embryonated eggs or larvae of C. externa showed significant reductions in the mean numbers of thrips, about 9 days after the release of the predator on the plants. The potential of C. externa as a biological control agent for thrips is discussed.
