Abstract

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.

 

Este estudo teve como objetivo investigar a dinâmica de predação de Chrysoperla externa Hagen (Neuroptera: Chrysopidae) sobre Enneothrips flavens Moulton (Thysanoptera: Thripidae), por meio da liberação de ovos embrionados e larvas de primeiro instar de C. externa em plantas de amendoim cultivadas em casa de vegetação. As plantas que receberam ovos embrionados e larvas de primeiro instar de C. externa apresentaram redução significativa no número médio de tripes nove dias após a liberação do predador. O potencial de C. externa como agente controlador foi discutido no contexto de controle biológico de tripes.
