Ichneumonidae (Hymenoptera) parasitoids of Lepidoptera caterpillars feeding on Croton floribundus Spreng (Euphorbiaceae)

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 Förster (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
