Ficus benjamina L. (Moraceae) is an exotic ornamental plant in Brazil. The aim of this study was to identify a defoliator and its parasitoid on F. benjamina plants in Vicosa, Minas Gerais, Brazil and to determine the number of pupae and the emergence of lepidopteran and a dipteran. Four Halysidota sp. (Lepidoptera: Arctiidae) groups, with 158, 144, 137 and 129 last-instar caterpillars aggregated on the trunks of 4 F. benjamina trees. These caterpillars were collected, held in plastic containers with ficus leaves until development and emergence were completed. Adults of 1 undescribed lepidopteran species ( Halysidota ) and 1 dipteran species [ Belvosia (Tachinidae)] emerged from the Halysidota pupae. An average of 118 viable Halysidota pupae per group were formed, and an average of 62.5 Belvosia individuals emerged from these host pupae per Halysidota group. From a grand total of 472 Halysidota pupae only one adult emerged. Halysidota sp. damaged F. benjamina plants in Vicosa, Minas Gerais, Brazil, but this defoliator was parasitized by Belvosia sp. The findings reported here indicate that Belvosia sp. appears to have the potential to reduce populations of Halysidota sp. and possibly protect F. benjamina in ornamental plantings. Ficus benjamina L. (Moraceae) e uma especie ornamental exotica cultivada no Brasil. O objetivo foi identificar um desfolhador e seu parasitoide em plantas de F. benjamina em Vicosa, Minas Gerais, Brasil e determinar o numero de pupas e a taxa de emergencia dos Lepidoptera e dos Diptera. Quatro grupos de Halysidota sp. (Lepidoptera: Arctiidae), com 158, 144, 137 e 129 lagartas de ultimos estadios agregadas sobre os troncos de 4 arvores de F. benjamina foram coletados. Uma especie nao-descrita de Lepidoptera ( Halysidota ) e outra de Diptera [ Belvosia (Tachinidae)] foram obtidas. Os numeros de pupas foram, em media, de 118 por grupo. A taxa de emergencia do Diptera foi de 62,5 individuos por grupo de lagartas. Halysidota sp. danificou plantas de F. benjamina em Vicosa, Minas Gerais, Brasil, mas foi parasitada por Belvosia sp. Isso mostra a importância desse Tachinidae para reduzir populacoes deste desfolhador de F. benjamina , a qual e cultivada como ornamental. View this article in BioOne
