Hyperparasitoids use the immature offspring of other parasitoids for their development, which may reduce the efficiency of biological control. The aim of this study was to evaluate the hyperparasitoidism by Brachymeria koehleri Blanchard (Hymenoptera: Chalcididae) in Lespesia melloi Gil-Santana, Nunez & Nihei (Diptera: Tachinidae) pupae parasitizing Thagona tibialis Walker (Lepidoptera: Lymantriidae) caterpillars in Brazil. Fifty pupae of various ages of T. tibialis were collected after the caterpillars had defoliated a Terminalia catappa L. (Combretaceae) plant on the campus of the Federal University of Vicosa (Vicosa, Minas Gerais, Brazil). Each pupae was held individually under controlled conditions until the emergence of either the lepidopteran or the parasitoid. Thirteen T. tibialis pupae yielded L. melloi puparia, which resulted in the emergence of 8 L. melloi individuals, 1 B. koehleri female, and 4 unviable pupae. This is the first report of hyperparasitism by B. koehleri of L. melloi pupae parasitizing T. tibialis caterpillars in Brazil. Hiperparasitoides usam a prole de outros parasitoides para seu desenvolvimento, o que pode reducir a eficiencia do controle biologico. O objetivo deste estudo foi avaliar o hiperparasitoidismo por Brachymeria koehleri Blanchard (Hymenoptera: Chalcididae) em pupas de Lespesia melloi Gil-Santana, Nunez & Nihei (Diptera: Tachinidae) parasitando lagartas de Thagona tibialis Walker (Lepidoptera: Lymantriidae) no Brasil. Cinquenta pupas de varias idades de T. tibialis foram coletadas apos suas lagartas terem desfolhado uma planta de Terminalia catappa L. (Combretaceae) no campus da Universidade Federal de Vicosa (Vicosa, Minas Gerais, Brasil). Estas pupas foram individualizadas e mantidas em condicoes controladas ate a emergencia de lepidopteros ou parasitoides. Treze pupas de T. tibialis apresentaram puparios, resultando na emergencia de oito individuos de L. melloi , uma femea de B. koehleri e quatro pupas foram inviaveis. Este e o primeiro relato de hiperparasitoidismo por B. koehleri em pupas de L. melloi parasitando lagartas de T. tibialis no Brasil. View this article in BioOne
