Extracts of 12 Asteraceae were tested on Spodoptera frugiperda (Lepidoptera: Noctuidae) and on their parasitoids Telenomus remus (Hymenoptera: Scelionidae) and Trichogramma pretiosurn (Hymenoptera: Trichogrammatidae). The plants Lychnophora ericoides and Trichogonia villosa were toxic for 97.7 +/- 0.15% of one-day-old eggs of S. frugiperda and Lepidaploa lilacina for 72.0 +/- 2.50% for two-day-old eggs of this insect. Extracts of Vernonia holosenicea, Lychnophora ramosissima and Chromolaena chaseae had higher impact on S. frugiperda, while those of Eremanthus elaeagnus and L ericoides were more selective to T pretiosurn and T remus. Asteraceae extracts present potential for integrated pest management programs of S. frugiperda. (C) 2009 Elsevier B.V. All rights reserved.
