ABSTRACT
Parasitoids of the family Ichneumonidae (Hymenoptera) were obtained during an inventory of Lepidoptera larvae caught feeding in the wild on Croton floribundus (Euphorbiaceae). The Lepidoptera larvae were collected from host plants along trails inside three preserved forest areas in the Brazilian state of São Paulo. Fifteen different species of Ichneumonidae belonging to five subfamilies (Banchinae, Campopleginae, Cremastinae, Mesochorinae and Metopiinae) were obtained. Seven species of Ichneumonidae were reared from leaf rollers: Meniscomorpha sp. (Banchinae) and Leurus caeruliventris (Cresson) (Metopiinae) from Dichomeris sp. (Gelechiidae); Mesochorus sp.1 (Mesochorinae) [as a parasitoid of Hypomicrogaster sp. (Braconidae, Microgastrinae)], Campoplex sp. (Campopleginae) and Leurus sp. from Olethreutinae sp. (Tortricidae); Sphelodon annulicornis Morley (Banchinae) and Eutanygaster brevipennis Cameron (Cremastinae) were also reared from two unidentified species of Gelechiidae. The other eight species were reared from the larvae of exposed feeders: Diradops sp. (Banchinae) from Miselia albipuncta Hampson (Noctuidae), Casinaria sp. (Campopleginae) from Hymenomima conia Prout (Geometridae), Charops sp. (Campopleginae) from Bagisara paulensis Schaus (Noctuidae) and Oxydia vesulia (Cramer) (Geometridae), two species of Hyposoter Fõrster (Campopleginae) from Semaeopus sp. (Geometridae) and H. conia, two species of Microcharops Roman (Campopleginae) from B. paulensis and an unidentified species of Limacodidae and Mesochorus sp. 2 [reared from what was probably Aleiodes sp. (Braconidae, Rogadinae)] from an unidentified species of Noctuidae.
Parasitóides da família Ichneumonidae (Hymenoptera) foram obtidos durante um inventário de larvas de Lepidoptera sobre Croton floribundus (Euphorbiaceae). As larvas de Lepidoptera foram coletadas sobre as plantas que ocorrem nas bordas de caminhos em três áreas preservadas de mata do Estado de São Paulo, Brasil. Quinze espécies pertencentes a cinco subfamílias (Banchinae, Campopleginae, Cremastinae, Mesochorinae and Metopiinae) foram registradas. Sete espécies de Ichneumonidae foram obtidas de larvas que elaboram abrigos: Meniscomorpha sp. (Banchinae) e Leurus caeruliventris (Cresson) (Metopiinae) parasitóides de Dichomeris sp. (Gelechiidae); Mesochorus sp.1 (Mesochorinae) [parasitóide de Hypomicrogaster sp. (Braconidae, Microgastrinae)], Campoplex sp. (Campopleginae) e Leurus sp. sobre Olethreutinae sp. (Tortricidae); Sphelodon annulicornis Morley (Banchinae) e Eutanygaster brevipennis Cameron (Cremastinae) parasitóides de duas espécies não identificadas de Gelechiidae. As outras oito espécies foram obtidas de larvas encontradas em situações expostas: Diradops sp. (Banchinae) sobre Miselia albipuncta Hampson (Noctuidae), Casinaria sp. (Campopleginae) sobre Hymenomima conia Prout (Geometridae), Charops sp. (Campopleginae) parasitóide de Bagisara paulensis Schaus (Noctuidae) e Oxydia vesulia (Cramer) (Geometridae), duas espécies de Hyposoter Fõrster (Campopleginae) sobre Semaeopus sp. (Geometridae) e H. conia, duas espécies de Microcharops Roman (Campopleginae) sobre Bagisara paulensis e Limacodidae sp., e Mesochorus sp. 2 [provavelmente parasitóide de Aleiodes sp. (Braconidae, Rogadinae)] sobre espécie não identificada de Noctuidae.
